Cassia III free porn video

Cassia III By: Ryker Several months later, the changes to my body were progressing. When I looked in the mirror I saw more female than male, and my emotions were a mess. No one looking at me would ever think I was a man without looking between my legs, especially with the "all natural" D-cup breasts hanging from my chest. Now it was confirmed my balls and cock have shrunk, just a little bit. I cried myself to sleep the first few nights after I realized it, and Cassia even comforted me a few times. The biggest shock, however, was when my Adam's apple all but disappeared and my voice became higher and more girlish. I didn't even know that was possible, but Cassia reminded me that her treatment was a radical form of gene therapy that altered my body on a cellular level. She explained the process in more detail, but I didn't really understand much of it. Our relationship progressed during these weeks, as well. It's amazing how things you thought repulsive could become an accepted part of your life with enough repetition and some helpful drugs and mind-fucking from a psychotic mad scientist. Most of the time I didn't have to wear the penis gag anymore, and for some unfathomable reason I was genuinely thankful to Cassia for that. Of course when I talked back to her or begged her too often to let me cum, it went right back in for a few days. Depending on her mood, she'd often reprimand me too, which usually meant my ass or ball or breasts were left in throbbing pain for a few hours. And since my gag needed to stay locked in until I learned my lesson, it meant I couldn't suck her cock at night, so she took it out on my ass. The last time Cassia rewarded me for good behavior, she offered to remove my corset as well. It felt soo good to finally be rid of that infernal device and breathe fully again. I thanked her profusely when she took it off me and even begged her to let me show my appreciation by showering her with kisses and sucking her cock right on the spot. It took me a few days to get back to taking full breaths again, and I made sure to be on my best behavior since, so it would stay off. I still wear my skimpy maid uniform and my other bondage devices during the day. Cassia explained that I probably do not need most of them anymore, but keeping me in my collar and cuffs and chastity belt while the vibrator constantly stimulated me was such a turn on for her. Thankfully, I was allowed to cum more often as well. If I was on very good behavior, it could be as often as every two or three weeks. But the slightest misstep, or if Cassia was in a foul mood for whatever reason, meant I could still earn a brutal ass-raping occasionally. She even lightened my housekeeping duties so I could spend more time with her in her study. We talked sometimes, mostly about my treatments and progress, but a few times she would ask my opinions about various things. Most of the time I spent under her desk sucking her off when she was working on a problem or dancing and playing with myself for her. She hired a stripper to give me dance lessons and made me perform for her, sauntering round the room or giving her lap dances. Of course the lap dances invariably led to us making out and then me giving her a blowjob or her fucking me. I came to realize that after a long day at her desk or in her lab, Cassia preferred to rest in the evening and have me pamper her and worship her body. So, she was often resentful and brutal on my ass when she decided I needed to be fucked at night instead. Speaking of being pampered, Cassia spent most days working on her research, but occasionally she took a day off to rest. She spent most of the day lounging around the house reading or bathing in the sun by the pool. I was relieved of my house chores for the day, and dressed in sexy, revealing lingerie, so I could spend the day at her feet rubbing her legs and licking her ass or her balls and cock. After resting for a while she would usually hit her personal gym, where she had several exercise machines. There was also a floor mat with some bags and wooden dolls for her to keep fit and practice her devastating fighting skills. I would attend her and wipe down her equipment. Afterwards, she almost always made me give her a tongue bath and blowjob. Then I would bathe her, massaging her body and rubbing her skin with sweet smelling ointments and lotions for hours. These days were completely about her, and if I showed even the smallest sign of thinking about myself, my punishment for ruining her day of rest would be severe. On the plus side, if the day went well, I would often be rewarded and allowed to cum the next day. So, of course, I tried extra hard to shower her with affection and not ask her to let me cum on those days. That was a task that was becoming harder and harder for some reason. Cassia suspected my sex drive and sensitivity in my erogenous areas were increasing due to the treatment, and naturally the vibrator was aggravated the situation. I actually craved getting fucked once in a while so I could feel the stimulation on my prostate! My orgasms were much more intense than I ever had as a man, adding to the temptation. Sometimes, she would unlock my cock cage and stroke my penis while fucking me to test my limits. I was rarely able to resist begging her to let me cum in these situations. Unfortunately, I was rarely allowed to finish, "because she needed to keep me reasonably aroused at all times for her research." Nothing personal, of course. Although, one time she accidentally brought me too close to the edge, and I came in her hand. Obviously it was my fault, and she was livid. She spanked my ass harshly and gagged me for the rest of the day after I licked up the mess. That night when I went to her bedroom, she raped my ass twice and then decided, "Since you think you need to cum so desperately, I think this time I will oblige you." She pumped up my vibrator to level five, stroked my overly stimulated cock, and teased my hypersensitive nipples until I came several times and was begging her to stop. Even after she stopped teasing me, she left the vibrator turned up until it died. Cassia brought home another guy one night, which went much like the previous time. They made out and fucked while I watched, and then I was forced to lick up the mess. Thankfully, this guy refused to fuck me even with some encouragement from Cassia. So she fucked me instead while he watched. Cassia also brought home a woman one time. I enjoyed that much more. Cassia fucked her first, and then after she asked the woman if she wanted to fuck me using a strap-on. The girl seemed attracted to this idea, so it took little coaxing to get her going in my ass. Afterwards I was ordered to thank her for fucking me by licking her pussy and ass and giving her a few more orgasms while Cassia played with her body. Cassia also started taking me out with her. She warned me that her research was very important to her and that if I did anything to jeopardize it or expose her, she would make sure I spent the rest of my life as a wall hanging in Mistress Donna's dungeon. I believed her completely. Most of the times she would just bring me along when running errands and leave me in the car, but sometimes I was allowed to walk with her depending on where we were going. Once she brought me to some kind of research facility after hours and hooked me up to a machine that took some readings. When I asked what it was, the answer was way over my head. Then one night she dressed me in a very tight-fitting black dress, tied my arms behind my back, and strapped me up in my corset again. The position forced me to arch my back and stick my breasts way out in front of me. I fought hard to resist the urge to protest, my mind whirling trying to figure out what I had done to deserve this. When she saw my face she must have known what I was thinking, because she assured me I was being a good little sissy, but we were going out to a new, special place to have a little fun. Cassia dressed in very sexy, skimpy white dress. We rolled up to a warehouse building in a seedy part of the city, and she wrapped an overcoat on me as we walked down an alley and into a side door. Inside was a large open floor club with a dance floor and DJ set up in the center of the place. Along the back wall was a bar and sitting area and a door leading farther back into the building. On the far side of the room, a small stage was set up where a man was spanking two women that were tied up in front of him. On the near wall were several bondage devices with people chained to them. Most of the people were dressed in leather with many in bondage similar to me. I'd heard of these BDSM clubs before, but had never seen one in person. Cassia removed my coat and led me towards the back by the leash on my collar. We passed several people grinding against each other on the dance floor and people locked to various devices, including a woman chained to a bed smiling seductively to everyone who came close. Cassia stopped near the dance floor and watched people dancing while pulling my dress down to expose my breasts and running her hands over me. She reached down and turned my vibrator up to level three, saying she wanted me to feel more aroused while we were having fun here. She ordered a drink when a serving girl came around, and sipped it as she played with me. After a while she announced she had to use the restroom, so she locked my gag in me and wrapped my leash around a nearby railing. Several people stared at me and a few groped me as they passed. I thought about causing a scene a few times in hopes that I could finally be rescued from my captivity, but when I finally worked up the nerve, I thought of the poor sissy at Mistress Donna's dungeon strapped to that horrible torture device and chickened out at the last moment. Two guys summoned the courage to come over and play with me, running their hands over me and fondling my breasts. When one of them found my penis, they started laughing at me, but didn't stop playing with me. I hoped Cassia would chase them away when she returned, but she started chatting with them instead. They remarked how sexy I was and that they'd never seen a dickgirl as good-looking as me. One of them took more than a passing interest in Cassia, too. She teased the guys about reserving a private room later and said goodbye as she unlocked my leash and led me back towards the sitting area. I tried begging her with my eyes against going into a room with the two men, but if she noticed she didn't let it show. She sat down on a couch and ordered another drink while I knelt in front of her, and she buried my head in her crotch. I stayed there as she ran her fingers through my hair and enjoyed her drink. A good-looking blonde woman sat down on the couch nearby, and after a few minutes Cassia waved her over. She and Cassia made out for a while, and then Cassia unlocked my gag and instructed me to lick her pussy and make her orgasm as they continued to kiss and touch each other. It became apparent to me that we had a small audience watching us. When I got the woman to cum, they applauded and moved on. "Thank you, miss, for letting me lick your lovely pussy," I said, dutifully. Cassia and the woman talked girl talk for a little while longer as Cassia encouraged the woman to play with my body. I thought again about making a scene and calling for help now that my gag was unlocked in a public place, but I froze up and realized I would never try anything with Cassia so close to me no matter what. Somehow, she had me terrified of her greatest wrath beyond reason. When they said their goodbyes, Cassia brought me over to the dance floor and started to dance around me, rubbing her body up against mine. She encouraged me to sway my body to the music, but I didn't feel very graceful in the corset with my arms tied tightly behind me. When my cock started to buzz, I began to panic, but Cassia whispered into my ear, "Shh. It's OK, sweetheart. Your chastity can be used to give you pleasure, too," and she leveled me with a playful grin. She whirled behind me rubbing against me and playing with my shoulders and sensitive breasts. It felt so good, I couldn't suppress a sigh of pleasure. Between her hands running over my nipples and the stimulation in my ass and on my balls, I was soon moaning shamefully. Other dancers were watching us, clearly amused at the scene before them. Cassia whispered to me, "Oh, you love this! Try not to cum yet, sweetheart." But despite being locked in my cage and the discomfort it caused, I was getting close to orgasm. When she saw me gasp for breath, Cassia cupped and massaged my breasts while flicking my nipples with her fingers and nibbling on my ear. It was too much. My cock hurt inside its cage, but I still felt the stream of cum flowing from me as I moaned aloud. The audience around us cheered and clapped loudly as I orgasmed. When I was finished, Cassia informed me we couldn't leave the floor dirty with my cum, so I was forced to lick it up. I tried to apologize for cumming without permission, but Cassia put her finger to my lips and hurried me to the back corner of the large room. She pushed me up against the wall, fucking me from behind. She was so turned on it didn't last long until she exploded in my ass, and then she rushed us out of the club, barely remembering to grab our coats. On the way home, she still had that wild look in her eye and fondled me roughly me as she raced through the streets at dangerous speeds. When we got home, Cassia was all over me, tearing off my corset, for which I thanked her earnestly, and roughly kissing me and fondling me. Then she brought me down to her crotch, and I sucked her for a while before she turned me on my back, spreading my legs. She fondled my balls for a bit and then took me in my ass hard and long, but not as cruelly as during my ass-raping sessions. My arms ached under me, but I knew better than to complain. She started to thrust into me deeper and faster as she played with my tits and balls until she came deep inside me. Spent, she fell over me, kissing me softly and said, "That was great, sweetheart! Thank you for the fantastic fuck." "I am so honored that I was able to please you with my mouth and asshole, Miss Cassia. Thank you so much for fucking me and using me for your pleas ..." She silenced me by planting a big kiss on my mouth and gently twisting my nipple. She whispered in my ear between kisses, "You were wonderful tonight, sissy. I'd let you cum, but sadly you already did, and shamefully in front of all those people." I knew a reply was expected of me, so I said what I knew she wanted to hear, "I'm so sorry I came before you gave me permission, Miss Cassia. Please punish me to teach me proper respect for you." The last words were difficult because I knew she often obliged them. She giggled and said, "Don't worry, sissy. It made for a great show, and you made up for it, tonight. I won't punish you this time." I started to thank her again for her mercy, but she pressed her lips onto mine and kissed me passionately while continuing to caress my body. Gradually her kisses stopped and she fell asleep on top of me. ---- The next time we went to the BDSM club, Cassia strapped me into my corset, but kept my hands tied in front of me. Once we were inside, Cassia went straight for the dance floor. We danced for a little while with me mostly swaying to the music and Cassia whirling around me and groping me as she passed. When she was bored of that, she led me off the floor and ordered a drink. It didn't even come yet when Cassia walked off toward the back of the room dragging me along by my leash. She walked straight up to this large black man and bumped him on the shoulder. He turned and smiled at her. "Hey, gorgeous! You found us!" "Next time you move this place you should tell me," she teased, and gave him a kiss on the cheek. He looked at me. "Is this a new sissy? She's really cute! Amazing, actually." Cassia introduced me as her "new lover" and turned to me. "This is Dr. Morgan. You will respect him as you respect me." Then another man came up to us, and Dr. Morgan introduced him as his friend, Jeremy. With a nod from Cassia they moved up to me and sandwiched me between them while running their hands all over me. "You three have fun. I'll be right back," Cassia said with a playful smile. I wanted to tell her not to leave me with these two men, but I knew better than to say anything. Stuck between them, I had nowhere to go. Dr. Morgan was behind me and playing with my breasts while Jeremy was in front of me, kissing me and running his hands up my leg. When he moved to my inner thigh and started stroking upward, I started to panic. Jeremy wasn't here when I was introduced to Dr. Morgan, and some guys might not respond well to find out they are kissing a guy. "Please, wait. I don..." Suddenly my head was reeling as Dr. Morgan slapped me across the face. Whenever Cassia slapped me, it stung sorely. When Dr. Morgan slapped me my vision blurred, and I went dizzy. Only the two men's bodies kept me from falling to my knees. He whispered in my ear, "Shh, sissy. I know Cassia very well, and I know you should not speak without permission. Are you going to be a good girl for me, or should I slap you again?" I tried to respond but only ended up nodding absently as I tried to clear my head. The two men continued groping me and when Jeremy reached my crotch I held my breath. "Whoa, she's a dude!" he said, and Dr. Morgan smiled knowingly at him. The discovery didn't stop Jeremy from continuing to play with me and kiss me. I was actually sort of thankful for that. It could have gone worse. When Cassia got back, she asked, "Do you want to have some fun?" Though she said it generally in our direction, somehow I got the impression I was not expected to offer an opinion. Dr. Morgan said, "Sure, doll. Lead the way. This should be fun. Your sissy is rather fresh, huh?" Cassia gave me a hard look and stroked my face where Dr. Morgan slapped me, but said nothing. She just started walking towards the door on the back wall. Dr. Morgan followed her taking up my leash, while Jeremy was behind me pinching and poking my ass as we walked through the door. We entered a long hallway with several doors on each side. At the far end of the hallway I could see the building open up to a large room that looked similar to Mistress Donna's dungeon with plenty of toys for the fetish freaks to play on. We entered one of the doors along the hallway and into a small, brightly-lit room with a large bed in the middle and two chairs off to the side. Large mirrors were on each wall and the ceiling. Cassia went for one of the chairs while Dr. Morgan got on the bed, dragging me with him on my hands and knees. When he pulled me close to his crotch, I tried to back up... right into Jeremy, who had followed us onto the bed. Here I was between these two large men, and I had a bad feeling I knew what was going to happen here. Then I felt Jeremy's cock sliding between my ass cheeks as he grabbed my hips and slapped me playfully. Dr. Morgan unzipped his pants, and out popped a huge monster of a cock. It was almost as big as Mistress Donna's dildo! "Lick it, sissy bitch," he instructed me. When I hesitated, and said, "Please," he grabbed me by the back of my head and mashed my face into his crotch. His cock and balls rubbed against my face and chin as he repeated, "I said lick it, slut." I heard Cassia giggle as I stuck out my tongue and licked his balls. It didn't taste the same as Cassia's. She was more sweet, while Dr. Morgan was salty and sweaty. "Tease his asshole," Dr. Morgan said as he backed up a bit to rub the tip of his cock against my lips. Jeremy removed my vibrator and did the same. When Jeremy penetrated me, I gasped and was rocked forward right onto Dr. Morgan's cock. I had been fucked by a guy and had to lick his cum, but I had never sucked a man's cock before. Well, technically, Cassia said her cock was a man's before it was hers, but somehow this was different. Not only that, but Dr. Morgan's cock was enormous, and it strained my mouth to accept him. Tears of shame and pain began to well in my eyes. I could feel that Jeremy was rather big, too, and it hurt as he slid in and out of me. Soon both men were rocking me back and forth fucking me from both ends as my breasts swung beneath me. I was sucking Dr. Morgan off the way Cassia taught me for no other reason than to end this situation more quickly, but he took it as enthusiasm. He started playing with my breasts and making me moan. Jeremy got into it too, squeezing and slapping my ass. Then my cock started to buzz, exciting me even more. What was Cassia planning now? I thought. She moved up to me and unlocked the top of my cock cage letting me loose while still keeping the base in place to stimulate me. She stroked my dick a few times to get me going. "Looks like she really enjoys getting fucked, boys!" she exclaimed. "Keep riding her!" I wanted to protest that it was Dr. Morgan's hands and the chastity belt that was rousing me, not being speared by two large cocks. But I just kept sucking Dr. Morgan, and soon he tensed and spit his load into me. He had a lot of cum, and it kept spilling into me, choking me, and running out of my mouth. I tried to hang my head, but he kept his cock inside my mouth as he continued to play with my breasts. I was getting close to orgasm when Jeremy started to buck me faster and slap my ass harder. We came at about the same time, him filling my ass with cum as my cum spilt onto the bed. When we were done, tears streamed down my face, and the two men rolled off the bed. I stayed in position, dutifully, as I knew I should from past experience. Cassia laughed and said, "Wow! Look at that. She came just from being fucked while sucking a big black cock! She didn't even need to stroke her little dick!" The two men laughed along with her, and one of them slapped me hard on the ass. I whimpered and cried, wanting desperately to explain that it wasn't the cocks that made me cum. I knew better, though. Cassia said goodbye to the two men and then crawled onto the bed with me. "That was so hot, sweetheart. You were wonderful!" she told me. "We still have some time on the room, and that made me excited. Clean yourself up and come suck my cock," she told me. I wiped my face clean and then crawled over to her and started sucking. She was so turned on, it didn't take long for her to ejaculate down my throat. When we were finished she locked me back up, and we left the room. On the way out I looked into one of the dim, adjacent rooms and noticed a crowd cheering me. On the wall was a window into the room we exited. It was a one-way mirror, and they all saw me getting fucked and sucking a man's giant cock, and it looked like I was loving it. My face turned red from pure embarrassment. I was sullen the whole ride home, but it didn't seem to deter Cassia. She stroked my breasts and caressed my thighs eagerly smiling the whole time. When we got home, she bent me over the couch and fucked me before kissing me passionately and telling me," Good job, tonight, sweetheart. I'd let you cum, but you already did that tonight." I was still feeling shamed from the other night when Cassia brought home another guy to fuck her - and me. I got used to most of the things she put me through - like I had a choice anyway - but I just couldn't get used to sucking a man's cock or having them fuck me. When I tried to plead with her about it the following day, she was firm, and I became upset. It turned into an argument, and I lost my head and called her a "crazy bitch." I knew it was a serious mistake as soon as I said it, and it caught us both by surprise. We just looked at each other, stunned, for a few seconds before she simply turned away and started walking out of the room. I tried to follow her pleading. "I'm so sorry, Miss Cassia! I didn't mean it! Please forgi..." She didn't even turn around. Her foot came lashing out behind her and struck me under my right lung driving the air out of me and dropping me to my knees. She was gone by the time I looked up and could drag myself to my feet. Later that day, when I went down to wait on her for dinner, I found my penis gag waiting for me instead. I knew I had to lock it on even if it would prevent me from pleading for her forgiveness when she cooled down. I didn't see her the rest of the night, and that meant no dinner for me either. When I went up to her room the door was closed and locked, so I slept downstairs. In the morning, she came for me and told me we were going out again today. I tried to see if there was any edge or malice to her tone, but her face was unreadable, and her words were calm and relaxed. She locked my hands behind my back and blindfolded me as we left. I wasn't sure where we were going, but it seemed like we entered the city. She got me out of the car and led me through a door before removing my blindfold. Then I saw the entryway for Mistress Donna's dungeon. I tried to plead with her through my gag and stepped back, but she pulled me close and warned me, "Do not embarrass me in front of Mistress Donna or you will stay here for a long, long time. Got it, sissy?" I nodded. "Good. You were very disrespectful to me yesterday, so this will be just a little lesson to help you remember." I was heavy with anticipation as we waited for Mistress Donna. It wasn't long before we were led into the back hallway. I cringed when I saw her. She looked me over with the eyes of a wolf. "This one is very pretty, Cassia! Was this really a man, or are you working on another woman?" Cassia laughed and pulled up my skirt to reveal my chastity belt. "Oh, you remember my little sissy, don't you?" she replied. The shock on Mistress Donna's face was plainly evident. She looked closer at me, and I saw her face turn to wonder. "Truly, you are a genius, Cassia!" It was several seconds before her face turned from wonder to disgust after recognizing me. "He's been misbehaving?" Mistress Donna asked. "Do I get to keep him now?" "Just for a little bit," Cassia said. "She had a little outburst and needs a little lesson. That's all." "Shame," Mistress Donna said. Then she stalked over to me and pinched my nipple, whispering, "Sooner or later, she will get bored of you, worm, and I'll get to keep you." A strong shiver crawled up my spine, and I had to fight every urge in my body not to plead Cassia to take me away right then. The two women chuckled at my reaction. Cassia handed Mistress Donna a small bag of my "things" before warning me to obey her, and said she would be back for me soon. I could only hope soon really was soon. Mistress Donna came over to me and removed a chain with two clamps from her leather outfit and attached the clamps to my nipples. I whimpered when they caught my flesh, and Mistress Donna smiled cruelly at me. She led me to the end of the hall before the stairs leading down into her dungeon. She removed some heavy weights from the wall and attached them to the chain clamped to my nipples. The pain from the weights was so terrible I bent over until they rested on the ground. Mistress Donna told me, "Meet my staff at the bottom of the stairs, maggot. And hurry up." Then she walked down the stairs, leaving me to manage them with those massive weights hanging from my nipples. I had to take the stairs one by one, sliding the weights to the next step each time. I knew I was taking way too long when I reached the bottom, and a woman dressed as a dominatrix was waiting for me. She unclamped the weights and led me to a small, nearby room without a word. She was trying to appear disgusted like Mistress Donna did so effortlessly, but she couldn't stop peaking glances at me as we walked. There was a wooden table in the middle of the room with bolts on top of it and a fucking machine with a rather large dildo at one end. I was forced up on top of the table, and the girl unclamped my nipples. The pain was almost as bad as when they went on. Then she went through the task of piercing my nipples and locking them down to the bolts on the table. She inserted the dildo into my ass and turned on the machine. As the dildo slid back and forth inside me, it forced me to rock along with it a bit, tugging on my newly pierced nipples painfully . I couldn't help from whining through my gag. The woman watched me for a bit in amusement before leaving me there. I didn't know how long I was there, sobbing from the dildo fucking me and the pain in my breasts, before Mistress Donna came in with two large male slaves. "Are we having fun, yet?" she asked. She removed the fucking machine, the nipple clamps, and my gag and said, "We are going to play a little game." The two men moved to either end of me, and I knew I was going to be fucked from both ends again. Mistress Donna went on, "Let's see who can last the longest before cumming. This slave will fuck you while you suck the other one's cock. If you can get them to cum before you do, you will not be punished - much. My slaves know what happens to them when they fail me, so they will try very hard to make you cum. You will learn soon enough." The man behind me started fucking me as the other inserted his cock in my mouth. Thanks to Cassia, I was an expert cocksucker, so the man in front of me didn't stand a chance. He started to cum before long, and I heard him sob as he did. I shuddered to think what Mistress Donna had in store for him, but I was glad it wasn't me who came first. The man's cock in my ass was rubbing my prostate and stimulating me, but he seemed to be getting more excited than me, and it gave me hope. But then I felt the pleasurable buzzing in my chastity belt and Mistress Donna smiled maliciously at me. Even with the pain in my ass and nipples, I started to moan. I couldn't help it, and soon I was cumming on the table under me. The man behind breathed a sigh of relief, and Mistress Donna walked up to me. She slapped my face hard several times and then cupped my chin in her hand, saying, "That was pathetic, bitch. You will have to learn how to pleasure a cock with your ass if you ever want to get out of here alive." Then she left the room with the two men. I didn't have to wait long before another woman came in with a whip. She made me stand off to the side of the table and clamped my new nipple rings to chains hanging from the ceiling. She pulled on the chains lifting my breasts until I was forced onto my toes to avoid excruciating pain in my nipples. Then she proceeded to whip me until I was crying and begging for mercy. I tried to double over in pain and almost lost my footing at least once, but the chains motivated me back onto my toes in short order. After the whipping, I was left there, straining to remain on my toes until Mistress Donna appeared in the doorway. At this point I wasn't sure if I was glad to see someone, even Mistress Donna, or if I'd rather be left in torment. She stalked around me, pinching me and slapping my welts painfully. Then she told me that because I showed disrespect for Cassia, I would remain with her until I learned how to properly please her and speak to her. She continued to play with me while coaching me how to speak in respectful responses. After she was done, she informed me one of her attendants would be by to feed me. A short time later a woman came in with a male slave holding a bowl of food that I found out later was dog food. I was so hungry and tired I probably would have eaten it anyway. She released me from the ceiling and told me to kneel before the man with the bowl of food, but I wasn't allowed to take the food. Instead she told the man to spread some of it on his cock, and I was forced to lick it off. When I finished the small bowl, which hardly sated me, I was once again chained to the ceiling, but fortunately this time I wasn't forced to my toes and even had a little bit of slack on the chains. The woman and the slave left the room, and she called, "Good night, slave." Wait. Good night? Like this? I wanted to call after her to beg her to tell me if she intended to leave me like this the whole night, but I was too tired, too humiliated, and I knew better. The night was extremely unbearable. I had to stand there all night long. I dozed off a few times and was jerked back awake from the pain in my nipples each time. I got very little sleep, and what I got was restless dozing. In the morning, I was released for breakfast, which was dog food licked off a slave's cock again, and then I was put straight into my "lessons." I was coached how to speak properly to a mistress and always show respect. At one point Mistress Donna told me, "Mistress Cassia is too lenient with you, letting you speak too often. From now on, you are to remain silent at all times unless spoken to. If you wish to make a request, you will get on your knees and bend over to kiss the floor and wait to be acknowledged. But you may only make a request this way when you do not have any other task assigned. Do you understand?" "Yes, Mistress Donna," I replied sincerely. Unsurprisingly, Mistress Donna and her dominatrices were much more strict than Cassia. I had to ask permission for everything in this way. I even had to ask permission to eat or use the toilet, and often forced to hold it for long periods. If I leaked, I was punished of course. I was punished often. Other lessons included how to read body language and behaviors to anticipate a woman's needs. Much of the time I was being fucked while sucking a cock and learning how please a cock with my asshole. I was taught to squeeze and massage the cock with my anus while sliding along the shaft and grinding my ass against the man's crotch. At night I was once again tied into a standing position, making it almost impossible to get any sleep. I was so sleep deprived, hungry, and well punished that I was delirious and lost all track of time. I wasn't even sure how many days I was there, but the lessons were continually beaten into me. By the fourth (or fifth?) day I was able to make the slave fucking my ass cum before I did and was spared a brutal whipping. The whippings ended after a few days to let my wounds heal, but Mistress Donna found other ways to torment me, which usually meant using a device to twist my body into an unnatural position. I was silently pleading incoherently for mercy when I heard footsteps approaching me one day, hoping that it would be anybody but Mistress Donna. When I saw that it was Cassia, I had to fight every urge in my body to grovel at her feet and beg her to take me away from there. Of course, I couldn't anyway, since I was tethered to the ceiling as usual when I wasn't being forced to suck a cock or getting fucked. One of Mistress Donna's dominatrices appeared behind Cassia, and I was instantly nervous about what this could mean. She stalked over to me and shoved my gag into my mouth, then released my nipple rings from the chains and proceeded to dress me in my familiar clothes and bondage devices. When I was given back to Cassia, I tried to plead for forgiveness with my eyes, but her expression was unreadable. The drive home was silent, and I was fast asleep from lack of rest during my stay of suffering. We started nearing the house when she pinched my nipple to wake me. When I was back to my senses, she asked me, "Are you prepared to be my obedient sissy lover again?" Her tone wasn't harsh, and she seemed to be asking me genuinely. I nodded vigorously. "I hope so. I missed you the last few days, and you were doing quite well before your little outburst. I hope I can trust you to get back to that standing." I nodded again, hoping she believed me. Once we were inside, she unlocked the cuffs binding my arms behind me, and as soon as I was free I dropped to my knees and threw my arms around her, giving her the tightest hug I could. After the time I spent in Mistress Donna's hell, I desperately needed Cassia to accept me back. She was so surprised by my action or she probably would have stopped me, thinking I was going to try something against her, but I had her in my tight embrace before she could react. After a few moments she recovered from her shock and reached down to put her arms around my shoulders and head, gently running her fingers through my hair. We held each other like this for a long time, and I felt her warmth against me, her the comforting, protecting arms holding me. She gently eased me back, and smiled warmly at me, "I'm glad to have you back. I really am, but it will take a few days before I can trust you again. Until then, I need you to be a very good girl for me. Do you think you can do that, sissy?" I nodded at her earnestly and mumbled a garbled "I promise" though my gag. "OK, sweetheart. Go get cleaned up, and then you may rest on our bed and wait for me. You don't have to resume your duties until you can rest up a while." I nodded, and she helped me to my feet before giving me a kiss on my forehead and sending me off. I walked away hoping Miss Cassia meant what she said about trusting me again. After washing up as she instructed me, I went to our bed and waited for my Miss Cassia, but I drifted to sleep before she came. I slept long and soundly. ~~~~ I walked into the room to find her unconscious on the bed. The poor thing must have been through a frightful ordeal, but she did bring it on herself, I thought. I moved up behind her and stroked her shoulder, but she was completely unresponsive and breathing the deep rhythmic cadence of REM sleep. I was looking forward to fucking her, but perhaps I can just enjoy her soft, tender body while she rests. The faint signs of whip marks still adorned her body as I stroked her skin, and I shuddered to think what she must have endured at Donna's. Fortunately, they didn't seem to penetrate her skin too much or damage her dermis or any subcutaneous tissue. She wouldn't scar with proper treatment, but still I didn't want to think of what Donna did to her there. It was necessary, I told myself. "I'm sorry I can't let you out just yet, sweetheart. I'm afraid I might hear those awful words from you again." No response. Her deep breathing went completely uninterrupted. I check her pulse. Normal. Restful. I reached to her ass to turn off her vibrator, but it was dead. The sight of seeing her prone before me so helpless and peaceful, turned me on. Maybe just a quick fuck. But when I pulled her vibrator free, I saw her anus was bruised and swollen red. My erection drained out of me. I retrieved some semiocclusive ointment from the bathroom and rubbed it into her anus and her skin. Through it all, she never moved an inch. So, I held her until I drifted off to a fitful sleep. ~~~~ It must have been late into the next afternoon when I awoke, because I was called for dinner soon after rising and getting ready. That night, I was allowed back into Miss Cassia's bedroom, but she said she still didn't trust me enough to unlock my gag yet. So, she fucked my still tender asshole instead, but fortunately it wasn't a harsh ass-raping. It was almost like making love. I tried using my new "ass fucking" skills on her, but she must have misunderstood what I was trying do to and reprimanded me to stay still even if it hurts. After my visit to Mistress Donna's dungeon, I wasn't going to push my luck an inch, so I just lied there and let Miss Cassia fuck me however she wanted. ---- The next few days Miss Cassia rarely spoke to me, but she was pleasant with me when she did. Once, I caught her looking at me with a sorrowful expression. I wondered what that meant and was afraid to find out. I was still locked in my gag with no relief except when eating, so there was no chance to find out anyway. The small rings remained in my pierced nipples, too. She seemed to be consumed by her work most of the time except when she took a quick break to fuck me briskly or eat. Was she avoiding me or just really busy? When I heard the doorbell ring, I wondered who was here. Miss Cassia must have known, because she instructed me to answer it. I opened the door to find Dr. Morgan standing on the stoop. He grinned at me widely when he saw me. "Well, hello there, sissy bitch! How you doin'?" I froze wondering what he was doing here and hoping he wasn't here for me. After a few seconds, I remembered myself and curtseyed to him. Then I lead him into a waiting room. He came up behind me groping my tits and grinding his crotch against the small of my back. He whispered into my ear "Did you miss me, sissy?" I didn't answer, and he just kept groping me. Miss Cassia came in soon after and laughed when she saw the scene. "You really like her, don't you, John?" she asked him. He just chuckled and let go of me. "Thank you for entertaining our guest, sweetheart," she called to me as she led Dr. Morgan to her study. They were there a while, and thankfully he left while I was busy upstairs tending to the guestrooms. He came by every few days, working long hours with Miss Cassia in her study. One day he came while she was out, so he played with me for a while until she arrived. He started groping me and kissing me on the neck. I was still wearing my gag; Miss Cassia didn't have much time for me except to fuck me during a break or at night. "It's a shame you have that gag locked on so tight, slut. I still remember the excellent blowjob you gave me last time," he told me. "You really should treat Cassia with more respect so that your lips will remain free to wrap around my cock." Yeah, that's why I should show her respect, I thought. Then he slapped me hard on my ass. The force of the blow nearly sent me reeling, and I yelped in pain and shock, but Dr. Morgan reached around me and grabbed my right breast, squeezing tightly and holding me up. He spanked me again and again on my ass and thighs harder than Miss Cassia or even Mistress Donna had ever hit me. By the fifth slap, I was sobbing and begging for mercy through my gag. "That's what I love about you little white chicks: your skin turns such a lovely, rosy red when I smack it," he said to me as he ran his hand over my ass. He continued to spank me several more times, rubbing my skin between slaps, until the only thing keeping me on my feet was his hand gripping my breast painfully. He looked me in the eye with another look of disappointment, and said, "I guess I'll just have to settle for slamming your ass." He chuckled, but it left me on the verge of panic. I recalled how Mistress Donna's dildo felt in me, and Dr. Morgan was nearly as big. The pain from my ass whipping combined with the thought of him fucking me had me swooning. Dr. Morgan took that as a compliment and lifted me up and carried me over to a sofa. He sat down and placed me in his lap facing him. When my ass cheeks touch his skin I winced with pain. "Take my cock out, sissy," he told me. I did. "Yeah, now stroke it." As I was giving him a handjob, I heard the side door open and was relieved to see Miss Cassia had gotten home, but I was not to be saved. "You two look like you are having fun," she said to us both. Then she walked up to Dr. Morgan and stroked the side of his face. "I be waiting," she said before walking away. "Ohh, and I was hopin' she was going to take your gag out," Dr. Morgan said to me when she was gone. "I bet you were hopin' the same thing weren't you?" I nodded. "Yeah," he continued, "you can't wait until you get to taste my cock again, can you, sissy bitch?" I shook my head in agreement, because I knew it was expected of me. "Well, I guess I'll just have to fuck you after all," he said looking into my eyes. I tried to keep the fear off my face, but I knew I was unsuccessful. "But, I'll tell ya what, sissy. If you promise to be a good girl for me, I'll let you drool over my cock before I stick it in your ass. Would you like that?" I nodded insistently, and squeaked a, "mpphhh," at him. He grabbed the back of my neck and pulled my face down onto the tip of his cock and held me there while I worked up enough drool to slobber onto him and continued stroking him. Then he shifted me forward onto his giant pole. As he entered my ass, I groaned in pain, and he pulled me down onto him fully and held me there. When I was able to get a hold of myself, I started gyrating on him and using my anus to massage his cock the way Mistress Donna taught me. I figured the sooner this was over, the sooner the pain would end. He obviously enjoyed it and was soon moaning in pleasure as he fondled my body, paying particular attention to my breasts. When I thought he was about to cum, he stood up, taking me with him, and laid me down onto the sofa and continued fucking me. He was so strong and so turned on that he slammed into me roughly. And he was so big that his thrusts were just as bad as any ass-raping session Miss Cassia put me through. I was soon screaming in pain and tried to push him back in desperation, but he held my hands over my head and continued to fuck me hard while mauling my breasts with his other hand. When he started to groan heavier, he pulled out of me and started cumming all over me. Just like in the club, he had more cum coming out of him than I had ever seen before in one place, and I was soon covered from my face to my belly in Morgan cum. "Wow, slut! That was incredible. You really know how to drive a cock wild!" He slapped me on my thigh causing me to cry out again and zipped up his pants. Then he leaned over me, getting close to my face. "Now, I want you to promise me that you will treat your mistress with respect. She deserves a lot better than you, and you aughtta thank her every day for givin' you any attention at all. So, the next time I come here, if you are still wearing that gag and can't suck my cock, I'm going to be very personally offended. You got me, bitch?" I nodded fearfully. Finally, he went off to find Miss Cassia. I just lied there sobbing and fighting away the lingering pain. --- Two days later, Miss Cassia called me into her study while working. I curtseyed to her, but she left me standing there for a while before looking up from her screen. "Have you been a good little sissy?" she asked me, her expression maddeningly unreadable. I nodded. "You seemed to be trying hard the last few days, and Dr. Morgan told me you treated him well. If you think you can behave yourself, maybe I can let you out to suck my cock?" She said it like a question as if wanting me to decide, but I knew she already had her mind made up. I nodded my head anyway. "Well, come here and show me." I went over to her, and she unlocked my gag, pushing me under her desk. "Thank you for trusting me, Miss Cassia. I'm so very sorry I was naughty." (Mistress Donna's words.) "I promise I'll never talk back to you again, and I'll only show you the utmost respect that you deserve. Please let me suck your cock and worship you with my asshole for my penance." She pushed my head onto her cock, and for the first time in over a week I sucked her until she was cumming in my throat. "Mmmmm," she said after her orgasm faded. "Ohhh, I missed that." When she let me up, I started into my usual post cocksucking gratitude, "Thank you, Miss Cassia, for allowing me to worship your cock with my mouth. To show my highest gratitude," I went on, "I would love to dance for you and please you with my ass the way Mistress Donna showed me." Of course I really didn't want to do this, but I knew if she found out about my new skills from Mistress Donna instead of me, I would be disciplined for holding out on her. Miss Cassia raised an eyebrow in interest and simply replied, "Okayyy." I danced for her a little bit before crawling onto her lap and grinding my crotch against hers and kissing her and rubbing her body with mine. She was hard again in no time. Then I slid her cock into my ass and rode her while massaging her cock with my anus, just like I did with Dr. Morgan. She was writhing and moaning in pleasure under me as I bounced up and down on her, showering her with kisses. She was getting close to orgasm again when she pushed me back over her desk, bending my back in a painful position. Now she was getting aggressive with her kisses and hands while pumping her cock in and out of me. "Don't stop," she told me, breathing hard over the words, and I knew she meant for me to keep flexing and grinding my anus on her cock. Finally, she pushed all the way into me and screamed loudly while filling me with another stream of cum. "Ohhhh myyy!" she exclaimed when she was done. "That was incredible! You learned that in twelve days? Amazing!" She sat back, drained, and smiling at me. Twelve days!? She left me there for twelve days as a "little lesson?" "Thank you Miss Cassia for letting me..." I hid my shock and began my obligatory appreciation. But she interrupted me and told me, "Shhh, baby. Get up here." She pulled me up onto her lap and began playing with my body, massaging my breasts and torso and kissing my neck. Then she unlocked my chastity belt and stroked my cock until I came. It felt so good to be able to cum without knowing a lashing was coming behind it. Miss Cassia brought my face to hers and kissed me passionately and then told me sincerely, "Thank you, sweetheart, for attending me so well today. I hope this means I can start trusting you again." I nodded eagerly and said, "Oh yes, Miss Cassia. I promise I learned my lesson and will live only to serve you in any way that I can from now on." "We'll see, sweetheart. But you took up too much of my time already, so run along and get back to your duties, so I can work," she said as she replaced my chastity belt. "Yes, Miss Cassia" I looked at my gag a second, dreading the thought of putting it back in before reaching for it, but Miss Cassia stopped me. "Let's see if we can leave that out for now." "Oh yes, Miss Cassia. Thank you. Thank you so much, Miss Cassia." I kneeled before and kissed her hand before scurrying out of the room. After I left, I considered my situation. It seemed I was back in her good graces, which was better than anything, and my tender asshole might get a chance to recover, but I wondered what kind of hole I had dug for myself. She would be looking for me to screw up now, and I showed her I could please her with my ass well as I ever could with my mouth. She'd likely be fucking me a lot more now and that made me cringe just a little. I was more than used to it by now, but that didn't mean I always liked it. Predictably, after dinner when I went up to her room, she had me suck her off for a little bit before turning me over and making me ride her to orgasm. Then she settled into bed to read from her notes while I licked her ass for the rest of the night until we both fell asleep. ---- True to his word, the next time Dr. Morgan came by, I sucked his cock. He was immediately pleased when he saw me without my gag and came up to me, playing with my tits roughly. I had to hide my grimace of pain as he manhandled me. "I see you have been a good girl for Miss Cassia. I like that, sissy. Do you want to be a good girl for me, too?" he asked me. "Yes, Dr. Morgan," I replied. "Good. And what would you like to do to show me?" "Please, sir, may I suck your big cock?" He laughed, "You know my cock is more than just 'big.' Say it like you mean it, slut." He squeezed my breast and smacked my ass, causing me to cry out. "Please, sir, I would thoroughly love to suck your fantastic, enormous cock," I forced myself to say (more of Mistress Donna's words). It seemed to please him. He breathed, "Yeahhh..." into my ear as he renewed his manipulations of my body. Then he gave me another smack and pulled me over to a chair. He sat in the chair, plopping me down to my knees on the floor. My ass was smarting from just the two slaps he gave me, but I held back my tears and reached up to free his big, black monster from his pants. I began stroking him and kissed and licked the tip until he was semi- hard. When I opened my lips to take him in, he grabbed me by the hair and eased me onto his cock until my lips stretched painfully to accept him. He fucked my face while I struggled to suck him off and caressed his balls. He kept me at it for a while, slowing down when he got excited, until he decided he was ready to cum. He jacked my face on his cock until I was deepthroating him violently and gagging helplessly. Finally he pulled out of me and unleashed his cum all over my face until I was swimming in it. It covered my face completely and spilled over my breasts and lap. "Thank you for allowing me to suck your awesome cock and covering me in your delicious cum, sir," I choked out, dutifully, as his cum dribbled out of my mouth. He just laughed at me as he got up and said, "Cassia turned you into a fine cocksucker, bitch. You will thank her for that when you see her." His tone made it clear it I was expected to follow through with his demand. "Yes, sir," I responded meekly. He left me there, crying quietly, covered in his cum, my throat burning from deepthroating him so intensely. ---- The next few days I noticed Miss Cassia seemed rather stressed, and she was often worn out at the end of the day. Thanks to my sessions with Mistress Donna, I also noticed she seemed to carry some tension in her upper back. One night she even passed on having me serve her in bed and went to sleep early. I knew it might be been a good opportunity for me to impress her by anticipating her needs. If she appreciates my attentiveness, it could lead to some benefit for me, I thought, and maybe I could even finally get this damn vibrator out of my ass for good. It was still a risk though. Taking any initiative with that volatile woman could always mean trouble, especially when she was agitated. When she left her study to use the toilet, I made up my mind and planted myself on the floor the way Mistress Donna instructed me. Miss Cassia open the door and paused a few seconds before asking me, "What are you doing, sissy?" "I noticed you seem stressed, Miss Cassia. Please allow me to tend to you and help you relieve your tension." I replied. She paused again before saying, "I would like that, sweetheart. Follow me." She led me to her study and sat in her chair, giving me room to crawl under her desk, saying, "I'm afraid I don't have time for a break now, but you may suck my cock while I continue my work." I nodded, and offered, "Yes, Miss Cassia. But if you like, I can rub the tension from your back and shoulders first. I noticed your muscles seem stiff." She nodded, and I got to work rubbing out her shoulders and upper back as she started typing at her keyboard. After a while she stopped working and just enjoyed the massage. When most of her knots were worked out, she stopped me and said, "Thank you, sweetheart. That was nice. Now come here. I need to talk to you." I wondered what this could be about with a little concern as I walked around her chair and knelt before her. "I talked to Mistress Donna, today," she began. Oh no, what now? I thought. Miss Cassia continued, "She seemed very impressed with your conduct while staying there, though she would never admit it. I am proud of you. And I've noticed you have been trying very hard these past few days to be devoted to my needs, and I appreciate that. I really do. But we have decided that you will be visiting her regularly." Instantly, fear and pain and shock spread through me like wildfire. When Miss Cassia noticed and paused, I couldn't help but plead with her as tears began to well in my eyes. "Oh please, Miss Cassia, please, do I have to? All she wants to do is hurt me so badly, and she's so cruel. I've been a good girl for you. Honest! Please don't send me back. I'll be better. I'll do anything! I promise. Please... Please." By the time I was done the tears were streaming down my face. "Yes, you have to," she replied firmly, but then her expression warmed, and she cupped my face in her hands and wiped away my tears. "And, yes, you have been behaving well. These sessions will only be for training, not punishment. I will tell Mistress Donna that you are not to be harmed any more than the lesson requires for as long as you serve me well." She could see I was gathering the courage to say something else; I just wanted to beg her more that I didn't need to go back, but I didn't have the words. She smiled warmly at me and said, "It won't be so bad, sissy. I promise. But now you have already taken up too much of my time. I need to get back to work, so you may tend to my cock now. If you do a good job, I'll have a very special surprise for you tonight." I sullenly crawled under her desk, and she slid her chair up to me. I began by tenderly licking her balls and cock. Then I took her into my mouth, slowly sliding her in and out of me as my lips softly caressed her shaft. It went on for quite a while this time, and I was getting fatigued when I noticed her typing and clicking became faster. When she finished, she reached down and gently guided me deeper into her with a nudge on the back of my head. I started massaging her cock with my tongue and stroking her shaft and balls with my hands the way she had taught me. Soon she pulled me all the way onto her and exploded into my throat. "Oh, that was wonderful, sweetheart. Thank you." "Thank you, Miss Cassia, for letting me pleasure you by sucking your beautiful cock," I recited one of my mandatory expressions of gratitude. "You're welcome, sweetheart. Let me work now." I curtseyed to her and left the room wondering what "special surprise" she had waiting for me. Part of me dreaded the thought. I entered her bedroom that evening with more than a little unease, but she invited me in warmly and started caressing me, partially easing my fears. She kissed me and touched me for a while, inviting me to respond the same way. After a little while, she gently pushed me down to her crotch, and I sucked her cock again until she came in my mouth. Then she softly pushed me down onto my back and locked my hands to the bedpost, and I started to wonder where this was going. She kissed me passionately and rubbed her hands all over my body. Then she unlocked my chastity belt and started playing with my cock. I was hard in no time, but Miss Cassia urged me not to cum until she was ready for me. Then she did something I never expected. She sat on top of my groin and guided me into her. I moaned in wordless passion. After so long, it felt soo good to feel the warm, soft embrace of her ass as she rode up and down on my cock while playing with my breasts. It was so intense I was writhing under her and gasping in pure ecstasy. I tried to hold off as long as I could, but finally I had to plead with her to give me permission to cum. She made me hold me off for a little while longer relaxing her movements on top of me. When I simply couldn't hold out any longer, I begged her, "Please, I can't... I can't hold it... any longer... I'm ... sorry. Please, please... let me cum!" She lifted off me and finished me with her hand until my cum shot onto my belly. I desperately wanted to cum inside her, but I didn't complain. It still felt absolutely amazing. She wiped up my cum with her fingers and fed it to me until my middle was clean. Then she moved up beside me, holding me and softly playing with my body. I thanked her profusely for giving me the great honor of allowing me into her, and admitted it was by far the best orgasm I ever had. "That was twice for you in as many days. I'm afraid you are going to have to wait a while before I can let you cum again," she told me. Part of me was obviously depressed from hearing that, but after the intense pleasure I just experienced and the contentment I was feeling from it now, I simply whispered an honest, "Yes, Miss Cassia," and let her play with me however she wanted. --- To be continued...
