Fooling Around With Her Sister's Boyfriend free porn video

I guess I was a bit of a late bloomer; I didn't have my first orgasm until I was eighteen years old. I had never been particularly interested in boys and sex and all that. My family wasn't well off, and if I was going to get into a decent university (unlike my sister Valerie who was still living at home and going to community college), I would have to get really good grades. I had tried masturbating before. Everyone said there was nothing wrong with it, that it's totally natural, etc etc. It just didn't do much for me.

So I was caught totally off guard when one night, as I was absently touching myself between my legs, I started to get seriously turned on. Nothing like that had ever happened to me before. It was kind of my habit to play with my pussy before I went to sleep; it was relaxing and felt nice. All of a sudden, my petting started feeling really good. I couldn't stop; I didn't want to stop. I could tell that my cunt had gotten really juicy. My clitoris seemed to have swollen until it was the size of a marble. I rubbed and rubbed until waves of pleasure washed all over me like surf at the seashore. So that was orgasm! It was the best feeling ever. I knew then that I had struck gold.

From then on I masturbated almost every day. Sometimes I would give myself two or three orgasms before I went to sleep. I thought about sex a lot. I was very curious. Mom had, of course, explained the mechanics of reproduction and the female body to me when I had first started getting my period. She was a nurse, and had given me a very thorough clinical explanation of sexuality. That was fine, as far as it went; I didn't want to end up pregnant; but I wanted to know about the good stuff.

I wasn't very interested in the boys at school, and frankly they didn't seem very interested in me either. I was kind of a freak. Sometimes I felt like a giraffe dressed up in girls clothing; I was taller than most of the guys in my senior class, and my butt and hips stayed distressingly wide no matter how much I worked out. As if to spite me, my top half was, well I wouldn't say flat, but I had nothing like the bust that my older sister proudly sported. To top things off, I wore glasses, I had broken my nose in a bike accident when I was ten and it was still crooked, and was I always studying, and got 'A's in all my classes. I wasn't exactly a boy magnet.

My friend Jenny lived up the block. We were the same age, and we had been best friends since junior high. Jenny was half Caucasian and half Vietnamese, and still had the body of a little girl. She was short and had curly black hair, and a flatter chest than me. From behind, you might have thought you were looking at a twelve year old boy. Puberty seemed to have passed her over. We had never really talked much about sex, but one evening she called over to our house. "Andrea, come over here! I found something I've just got to show you!"

Jenny had found a stack of old pornographic magazines in a box in her attic, and we looked through one of them that evening while her mom and dad were out. I had giggled and said "Ew gross!" the way I thought she expected me to, but secretly I had been incredibly turned on. I liked looking at the pictures of naked women exposing themselves so shamelessly; I loved their big tits and round asses, even though I thought they should have hairier pussies. There was a spread of two girls doing it to each other, which I had never thought of before, but I realized that I found the notion quite intriguing. Best of all, there had been pictures of a man and a woman actually doing it; having sex. I had never seen a naked man before, and there it was in all its glory, hard dick and all, sliding that big thing into that lucky models pussy-hole. By the time I went home, I was super turned on, all sensitive and juicy, and I couldn't wait to run up to my bedroom and play with my clitty. Maybe I could get Jenny to loan me one of the magazines. Or maybe, just maybe, Jenny would want to act out some of the pictures we had seen.

I hadn't expected anyone to be home at our house. Mom worked nights at the hospital, and Valerie was supposed to be out on a date. Valerie was 21 and she had a steady boyfriend, but she was a "good girl" and had told me before that sex was painful and gross, and that she was going to stay a virgin until she got married. Me, I had no intention of waiting that long. I didn't think that sex was gross at all.

There was a car parked in our driveway that I didn't recognize, but all the lights were off. I quietly let myself in and locked the door after me. I was about to head upstairs to my bedroom when a noise in the living room stopped me in my tracks.

Hardly daring to breathe, I tiptoed up the hallway and peeked in. There on the sofa was my goody-two shoes sister and her boyfriend, Mark.

Mark was 24, tall and slim, with thick rimmed glasses and unruly hair. I had seen him before, and I thought he was really hot. I didn't think he had ever noticed me before; he probably thought I was just a k**.

Mark and Val were on the couch, making out. They were kissing deeply, and Valerie's shirt was open, her bra unsnapped, and her big boobs were totally exposed. Mark was playing with her tits as they kissed, and she seemed to be encouraging him. Her nipples were erect, stiff and red and the size of gumdrops. I had always wished that I could have boobs like hers. From where I was standing in the dark hall, I could see the bulge in the front of Marks pants where his penis was straining to get out.

'I wish I was Valerie right now' I thought to myself. I was rubbing myself through my own pants 'I would be all over that action!'

As I watched, Valerie's skirt seemed to ride up all by itself. I saw her white panties, stretched tight over her pussy. Her legs seemed to spread as Marks' hand found its way down there, petting her through her underwear. I was creaming in my pants.

Suddenly Valerie stopped him. "That's enough!" she said in a voice that left no room for argument. I couldn't believe it! Neither could Mark. He begged, reasoned, and pleaded, but her mind was made up. No more fooling around.

"Besides, my little sister could get home any minute. You don't want her to catch us here like this do you?" My heart thumped in my chest.

"Could you at least give me a handjob?" Mark asked "I'm so turned on, I'm about to come in my pants."

"No way!" Valerie made a face. She relented a little. "I understand that guys have… needs. If you really need to, you can jerk off in the bathroom."

'Jerk off in the bathroom?!' I couldn't believe what a prude my big sister was! And what a waste! What was this totally hot guy doing dating her? He could have any girl he wanted. If only I was the older sister…

It was a split-second decision. Quiet as a mouse, I slipped into the hall bathroom and sat down on the toilet seat.

Mark walked in a couple of heartbeats later. He flipped on the light and closed the door. Then he saw me.

"Andrea!" he hissed "What are you doing here? What did you see?"

"Ssh!" I whispered "We don't have much time. I heard what Val said, and I felt bad for you. I'll give you a handjob."

"What? You're too young!"

"Am not! I'm eighteen." I said, eyeing the bulge in his pants lustfully. "Take it out, I'll show you."

Mark really wasn't in any condition to argue. He unsnapped his jeans, dropping them around his ankles. His hard prick eagerly sprang out of his boxer shorts.

I was a little surprised at how big it was. All that was supposed to fit up inside your pussy? Still, it looked really nice. I wrapped my hand around it. My fingers barely reached around its girth. It was scalding hot in my hand. He was rock hard and quivering. The mushroom shaped head was bright purple, and oozing clear liquid from his pee-hole. Tentatively I stroked him. I was surprised at how silky soft he was, despite being so hard. It felt really good to touch him. His balls were drawn up tight. 'How weird' I thought 'To have so much stuff hanging out between your legs!'

"Hurry up!" he whispered "I don't want Valerie to get suspicious."

It didn't take long. I loved stroking his cock. It made me feel incredible; powerful and sexy. I mashed my thighs together as I jerked him off, squishing my swollen cunt-lips together. I squeezed his penis hard and moved my hand as fast as I could. Suddenly it happened. He half moaned, half growled, and his entire body went rigid as he squirted glob after glob of pearly white juice out of the end of his penis.

"Don't stop" he whispered as I milked his softening prick. More and more leaked out. Of course I knew that sperm came out of a guys penis, but I had never imagined that it would be so much, or so forceful. How cool! It had gone everywhere; onto the wall, onto the toilet, on the floor, on my hand. I tasted a little. Not bad, a little salty.

"Mark, are you done yet?" Valerie was just outside the bathroom.

He kissed me softly on my head. "I'm just cleaning up. I'll be out in a sec!"

"Hurry up!" my sister said from out in the hall "I've got to go to the bathroom."

Mark and I hurriedly mopped up his semen with toilet paper and flushed the evidence down the toilet. He kissed me again, on the forehead. Then I hid behind the shower curtain.

I heard Valerie sit down and pee. I expected her to flush and leave, so that I could make my escape up to my bedroom. Instead, Christy stayed sitting on the commode. I heard little squishing noises, heard her breath change and become more rapid, and I knew that she was masturbating. I never would have imagined that she did it; she was such a good girl. Well, I had just given her boyfriend a handjob. I suppressed a giggle.

2.

I gave myself three or four orgasms that night, and more over the next couple days as I replayed the memories of sexy Mark and his big dick. I was hungry for more.

"Are you going out with Mark tonight?"

"Yeah" Valerie answered absently "We're going to see a movie. Why?"

"Could you get him to drive me over to my friends' house? Her mom said she'd drive me back home? Please?"

We both had our licenses, but Mom had taken the car to work. It took a little begging and wheedling, but Christy agreed to ask Mark for me. Mark didn't seem to mind much.

"Where does your friend live?" he asked as we drove down the block. The car was humming with sexual tension. I was wearing my pink party dress, which was a couple years old and a little small on me. It rode halfway up my thigh. I wasn't wearing any panties.

"Right there" I replied, pointing back at Jenny's house. "Keep on driving."

"Listen" Mark said "About the other night…"

"Did I do a good job?" I asked.

"Yeah" he said "Yes you did, but…"

I could see the bulge that had formed in the crotch of his jeans. I could tell he was at least as horny as I was. "I want to do it again" I said "I want you to teach me all about sex."

"We shouldn't. I'm too old for you. It wouldn't be right. I'm dating your sister." he added almost as an afterthought. "We can't have sex, Andrea."

"But we could do the other stuff" I persisted. I was a little disappointed; I was really looking forward to losing my cherry to him. But I wasn't going to give up that easily. "Like you could teach me how to give a blowjob."

He pulled up into a driveway, and used a remote controller to open the garage door, which closed after us. We were alone in the dark.

"This is my place." He said "Don't worry, my roommate isn't home. We don't have much time though. Valerie thinks I'm just dropping you off."

"Kiss me." I said. He hesitated. "I'm not in love with you or anything. Just kiss me, please."

We kissed for a while, and I thought it was really nice. I liked having his lips pressed against mine, his tongue in my mouth. I was starting to get super turned on. But he was right; we really didn't have much time. I would have to figure out a way for us to have some private time together. Meanwhile I wanted to use our time to the best advantage.

I broke off the kiss. "Would you like me to suck your dick?"

His penis could have answered for him: it was practically bursting the zipper of his jeans. "Only if you want to." he said.

Oh boy did I ever! Some of the girls at school talked about blowjobs like they were something gross; something that girls had to do in exchange for dinner and a movie. Not me. I thought it was super-sexy, and I couldn't wait to get my mouth on his thing.

He unzipped his jeans, letting his penis out. It was just as big as I remembered, if not bigger. (Looking back, I realize that he was about average size, maybe a little bigger. At the time though, his tool seemed the size of my forearm.) I didn't know how I was going to get that thing in my mouth, never mind my pussy.

"Just start by licking it" he said "Like a popsicle."

I lowered my head to his lap, stuck out my tongue, and licked the length of his shaft. He groaned as my tongue reached the sensitive purple head. I tasted the clear liquid that was oozing out of the end. It was sweet and sticky. I was hooked.

So was he, apparently. We took it kind of slow, with him stroking while I licked and (very gently) played with his testicles. As we got into it, and we both got more and more excited, I took the end of his penis in my mouth. I could only get about half of it in, and it filled up my entire mouth. It felt incredible. It was a little bit scary, having that huge living thrusting thing in my mouth like that. I was afraid I might choke, or accidentally bite him. Mostly though, it was just fun and sexy.

I felt his hand on my inner thigh, snaking up under my dress. As I kept sucking, I wriggled around to give him better access. His exploring fingers found my vagina. I reached down and helped him find my clit, which was screaming at me, and felt like it was about to explode.

Mark rubbing me was even better than me touching myself. He kept his fingers nice and slippery from my oozing vagina, and diddled my button until I thought I had died and gone to heaven. If this was what sex was about, I was all over it!

Mark's thrusting in my mouth was becoming more insistent as he fingered me. I concentrated (as best I could while his fingers drove me crazy) on sucking him as hard as I could.

"I'm going to come!" I knew what that meant. I wanted to make him do it into my mouth. His fingers momentarily stopped working their magic as his whole body went rigid and his ass lifted up off the drivers' seat. Suddenly, he was squirting hot, salty, sticky boy-come into my mouth. I swallowed and kept sucking. It wasn't nearly as much stuff as the other day, but it still felt like a lot. I swallowed all of it. I liked that he was really inside me now.

His fingers started up again as his shrinking wet dick plopped out of my tired mouth. My own body shook as his rubbing sent me over into orgasm. It didn't stop, it just kept going and going like a wild roller-coaster ride. I thought I was going to pass out as I ground my sticky pussy onto his hand.

At last it was over. I licked his finger off, and we put our clothes back together. I felt like I was floating. We kissed again, like friends this time.

He drove me back to Jenny's house, which was just three houses down from ours. On the way, he told me that he'd never done that before.

"What?" I asked "Gotten a blowjob or played with a girl's pussy?"

"Neither one." he said "Your sister is the only girl I've ever seriously dated, and… well you know."

I was amazed. Mark was 24, worked for a computer firm, and was gorgeous. "Have fun at the movies" I said as he dropped me off in front of Jenny's place "Who knows, maybe you'll get lucky tonight."

3.

I had dinner with Jenny and her mom and dad. It was hard not to tell her what I had just done. She was my best friend. But it was my secret. I thought about how bad my sister would feel if she ever found out, and I resolved never to tell.

After dinner, while her parents watched a movie downstairs, Jenny and I hung out in her room. She got a magazine out from under her bed. We leafed through it, giggling at the pictures and softly reading the stories aloud. I was thinking about the things I had just done with Mark, and getting excited all over again.

Finally I had to ask her. "Jenny, do you ever, you know, masturbate?"

She burst out laughing. "Yes! All the time! I was afraid you would think I was weird!" We both laughed and laughed with relief.

"Do you want to do it?" I asked when we had stopped laughing. "Now?"

"Together?"

I nodded.

"Ok."

We silently stripped out of our clothes and lay down, completely naked on her bed. We held hands as we started rubbing.

"How often do you do it?" she asked me.

"Basically every day." I answered "Sometimes more than once."

"Me too." she replied.

We started out lying side by side, but after a little while, we moved so that we were sitting on the bed facing each other. That way we could watch. Jenny's body was fascinating; all the same parts were there, but it was the differences that were interesting. She was a tiny little thing. Her boobs were smaller than mine, and her brown nipples stood straight out. She only had a thin triangle of black pubic hair, but her pussy lips were puffy and more prominent than mine. I could see her inner lips peeking out, glistening with moisture. I had never really looked at another girl naked before. I thought it was cool. I liked watching her play with herself. It turned me on.

"Oh Andrea" she half whispered "I'm going to come."

"Me too" I replied.

She spread her legs even further apart, and slipped one finger up into her hole as her other finger stayed busy on her clit. I copied her actions, feeling her eyes on my splayed vagina. We came at almost the same time. It was incredible.

"That was so much fun!"

"I'm glad we did that."

"I'm glad you're my friend."

After that, we got dressed, and I went home. Valerie wasn't home yet. I went to bed and masturbated one more time. My pussy was tender and sore, but satisfied. What a day it had been!

4.

That Saturday, Val and Mark were going to see a movie in the afternoon. Valerie asked if I wanted to come along

"s*s" I said, feeling guilty "I don't have to come. I don't want to screw up your date."

"It doesn't matter." Valerie said "We're just going to see a movie."

I don't even remember what the movie was about. I think it was a comedy. I sat next to Mark, and he sat next to Val. Hardly anyone else was in the theatre. Mark and Valerie held hands. I played with Marks penis through his pants. It felt naughty and exciting and super fun. He was so hard! I didn't want to make him come in his jeans. I was just priming him for later. When Val got up to go to the bathroom, I stuck my hand down his pants, and gave his hot erection a squeeze. He took the opportunity to reach between my legs, petting my pussy through my pants.

"Try and play with her pussy!" I whispered in his ear. "I bet she lets you."

When Valerie sat back down, Mark casually let his hand fall onto her lap. She didn't seem to mind. As I surreptitiously watched, his hand slipped under her skirt. She still didn't object. I softly stroked his penis through the denim as he played with Val's pussy under her panties.

After the movie, Valerie said she had homework to do. My bet was that she was going to go masturbate. I asked Mark if he would drop me off at my friends' house. He said sure.

"Did you make her come?" I asked as soon as we were alone.

"I don't know." he said "I don't think so."

"I want to taste your finger" I giggled "Is that weird?"

"I don't mind." he said, extending his finger for me. I sucked on it, pretending it was his dick. I thought I could still taste my sisters' pussy juice on it. I felt so horny I thought I was going to go crazy.
"Where are we going?" I asked.

"I don't know. We've got all afternoon, but we can't go back to my house. My roommate is there."

"What about the park?"

"It's a nice Saturday. Everybody will be there. But I do know a place we can go there. It's kind of a long walk."

We pulled into the state park. Mark was right; the parking lot was almost full. He took me along a hiking trail, deep into the woods. Abruptly, we left the trail, and made off into the forest.

This seemed private enough to me, although the ground was going to be a little scratchy. Mark pointed up ahead though. A finger of rock rose out of the ground, catching the sunlight. It was big as a house, and seemed unclimbable. I didn't know what he was planning until he pointed out a place where the rock jutted out. Behind that was a hidden gully that led straight to the top.

The top was like a stone table, smooth and bare and warm and sunny. "I found this place when I was a k**." Mark said "I don't think anybody else knows about it. I've never shown anyone before."

I was glad that Mark had shown me his secret place. It was really nice there. For a few minutes, we just sat together, enjoying it.

Mark lay down on his back, and I lay down on top of him. We kissed for a while. Then I sat up. "Take off your clothes" I said "I want to see you all the way naked."

"I want to see you too." He said as he stood up and started stripping. His body was beautiful. I loved seeing him naked. I could see all his muscles. He had the cutest tight butt. His penis hung thick and halfway hard between his legs. "Your turn." he said.

I felt suddenly self-conscious, but I stood up and started taking off my clothes. I hoped he wouldn't be too disappointed in my body.

"You're beautiful" he said, and from the sound of his voice and the look in his eyes, I could tell he meant it. I glowed.

"Did you like playing with Valerie while I played with you?" I asked "I thought it was really sexy."

His dick swelled at the memory.

"What did her pussy feel like?"

"Like yours, but more hair." He grinned.

"I think hairy pussies are nice." I said "I wish I had big boobs like Valerie's. Why do you think she's so weird about sex?"

He frowned "I think one of the first guys she went out with tried to **** her. She doesn't like to talk about it."

I thought about that. It kind of made sense. She had never said anything about it to me, but she was always warning me about guys, and she seemed so anti-sex, even though she had this hot boyfriend. Who I wanted to fuck, I thought guiltily.

"If Valerie ever has sex with you, will you still want to do things with me?" I asked.

"Yes" he answered "I sure will."

"Do you want to do things with me now?"

"Yeah I do."

"Do you want to fuck me?"

He looked at me. His dick was getting hard again. "We can't do that."

"You won't get me pregnant. I have a condom in my jacket pocket."

"I don't want to hurt you."

I pouted a little.

"Andrea" he said "I'm dating your sister. I'm in love with Valerie. I can't fuck you."

I guessed that was a line he couldn't cross. I didn't really understand the distinction, but I could hardly force him to fuck me. I figured I should be happy with what I had got.

"I'd like to eat your pussy." he said "If you'll let me."

Of course I'd let him! As soon as his mouth was between my legs, I was in heaven. His tongue was all over me, dancing around my pussy, tantalizing my clit.

"Put a finger inside me!" I begged. I was still turned on from the action in the theatre, and I knew I wouldn't last very long.

Gently, he complied. His finger felt huge invading the hole where only my small index finger had been before. For a second I was glad that he wasn't going to fuck me. I didn't know if he would be able to fit his penis in without ripping me in half! His finger was big enough! I gasped as he invaded me. It didn't hurt though, and as my little pussy got used to it, it felt really good, especially when he started moving it in and out.

He kept his tongue on my clit as he finger fucked my pussy, and I had an orgasm like I had never had before! I moaned and writhed and kicked my legs, but he held me tight against his face until I was all done.

I kissed him all over his face, tasting my tangy juice on his lips and chin. "Thank you thank you thank you!" I told him "Now it's your turn."

He let me explore all over his body. I kissed every inch of him, from his toes to his ears, avoiding for now the succulent treat between his legs. I sucked playfully on his nipples, which weren't that much smaller than my own. I kissed his hard tummy, sticking my tongue into his bellybutton, which made him giggle. I kissed his tight butt, and even kissed down into the dark musky crease between his cheeks.

At long last, I kissed my way up his ball sac, and finally put my mouth on his delicious cock. I could tell he was really turned on, and I wanted him to feel as good as he had made me feel.

He lay on his side as I curled up at his knees and sucked him. I still couldn't get the whole thing in my mouth, but I got as much as I could in, and stroked the rest with one hand. He started slowly humping my mouth. I knew he was being gentle and making sure not to hurt me, which I thought was sweet. He played with my hair while I sucked him.

I let my free fingers explore between his muscular butt cheeks. He didn't stop me, so I guessed he didn't mind. I thought his ass was so sexy. Touching him there, in that private place, made me just melt. I heard him groan, and his whole body quivered when I found the ring that I knew must be his butt hole. Ever so softly, not wanting to hurt him, hoping he didn't think it was gross, I tickled his butt. He seemed to respond by humping my mouth more urgently. His cock seemed to swell in my mouth. Throwing caution to the wind, I pressed my finger against his hole. He seemed to open right up, letting my finger in to the second knuckle. It felt incredibly sexy to be up inside him like that. As gently as I could, I started fucking his butt with my index finger, the way he had done my pussy before.

He erupted in my mouth, filling me with spurt after spurt of his semen. I hungrily swallowed it all. I kept sucking until his penis got too sensitive, and I had to let it out of my mouth. My finger popped out of his butt, and we cuddled in the sun, naked together.

I hoped he didn't think it was weird that I had played with his butt. He didn't say anything about it. After a while, we started to get turned on again. I could feel the end of his penis tickling my tummy. We kissed and touched for a little while, until he was rock hard again, and I was just melting. Mark rolled over onto his back, and I climbed on top of him, facing his toes, and we "69ed".


I just couldn't get enough of his dick. I licked and kissed it, mostly using my hand to stroke him so I could watch as he got more and more excited. I wanted to see him come again.

Meanwhile he was busy between my thighs. His kisses and licks down there were coming close to pushing me over the edge. My butt felt naked and exposed. I hoped that he would play with it the way I had done his.

I felt his breath between my butt cheeks, and then I felt his tongue exploring back there. I took a huge breath and started jerking his cock wildly. The sensation of his tongue near my anus was incredible. He slipped his finger into my ready pussy and tentatively licked my asshole. In seconds, I was coming again, wiggling my butt, trying to get more of Mark's tongue and finger inside me. He came too, splashing his white come onto my face and his tummy. There wasn't a lot this time, but it was thick and gooey. I licked up the droplets on his stomach, and he licked himself off my face. After a while, we got dressed again, and walked back to his car. He dropped me at the end of our block, and I walked home. I couldn't wait to get together with him again.

5.

Jenny had found something else in the box of dirty magazines. At the bottom of the stack, she had found a large manila envelope. In it were all the love letters her parents had sent while they were in college. Some of them were really explicit.

"Dear Jack" Jenny read aloud as she lay on her bed. I was leafing through an old Penthouse Magazine. We had told her parents that we were studying together. It was actually kind of true.

"'Last weekend was too wonderful for words'" Jenny read on. "'I get wet and have to touch myself just thinking about it. Five weeks seems like an eternity. I wish we went to the same school, or lived in the same town. I can't wait to see you again, to sleep next to you, to be in your arms, to have your hot cock inside me again.'"

Jenny looked over at me. "Oh my god" she said "I can't believe my mother wrote that. About my Dad!"

I thought it was hot. She read on "The next time I come over, I want to have you every way possible. After I suck you and you lick my pussy, I am going to climb on top of you and fuck you until you come inside me. Then, when you are ready again, I am going to make your dick nice and slippery, and I'll bend over and spread my cheeks wide and you can fuck me in the asshole."

"Can you believe this?" It was a little hard to picture: Jenny's dad was a big guy, and her mom was a tiny little thing, smaller even than Jenny herself. "She wanted my Dad to have anal sex with her. Do you think that's weird?"

I dodged the question. "Jenny, I need to masturbate. Is that ok?"

"Of course" she said "I'm horny too. Let's do it."

We quickly wriggled out of our pants and underwear, leaving our tops on. We lay on our stomach on her bed, silently reading more of her Mom's sexy letters to each other. I thought they were better than looking at pictures. Her Mom and Dad had had a really hot sex life. We played with ourselves as we read, getting more and more turned on.

Suddenly Jenny stopped reading and raised herself up on her elbows. "Andrea can I tell you a secret?"

"Of course" I said

"Promise you won't laugh at me or think I'm weird"

"Of course I won't. I'm your friend. What is it?"

Jenny leaned over and rummaged around under her bed. She had a really tiny little butt. I had an urge to caress her, but of course I didn't.

She came up with a big pink dildo. It was made of clear material with sparkles in it, and it was realistically shaped like a penis. It was even bigger than Mark's dick.

"Oh Jenny!"

"Sometimes when I masturbate, I use this" she said "Is that gross?"

"No!" I said "I think it's really sexy." I was tempted to tell her my secret, but I couldn't. "Maybe you could let me borrow it sometimes?"

"Sure" she grinned shyly "Any time you want. I used to use my hairbrush, but this is much better."

She pulled her shirt off and lay back on the bed, legs spread. She started rubbing the dildo up and down her slit. She turned a knob, and it hummed as she worked. She pressed the end of it against her entrance, and her pussy seemed to open up like a time-lapse picture of a rose blooming. I couldn't believe that thing fit inside her little body, but it slipped right up into her pussy.

"Oh Andrea" she moaned as she fucked herself "It feels so good! I can't believe you're watching me do this."

I couldn't believe it either. I was so turned on. I couldn't help myself; I knelt next to her and put my hand on the end of the dildo protruding from her pussy. She relinquished control, moving her hands up to her erect nipples.

I relished fucking her. I slid the dildo deep inside her and then pulled it almost all the way out. Her labia seemed to cling to it like a baby nursing a bottle. The pink toy glistened with her wetness. I pushed it back up inside her and she moaned. I fucked her harder and faster, until my arm started to ache. Her clit peeked out near the top of her vagina, pink and swollen and cute as a button. Not knowing what she would think, I lowered my mouth to her crotch. Still fucking her, I stuck out my tongue and touched her clit with the tip of my tongue. I heard her sharply inhale. I pressed on, licking her clit and fucking her pussy. She tasted tangy and nice. Her body twisted and shook, but I didn't stop. I kept my tongue pressed against her little clit and the dildo deep in her pussy until her body finally relaxed.

"Andrea" Jenny gasped when she found her voice again "That was beautiful! May I?"

I lay back and let Jenny crawl between my legs. Her tongue and fingers on my sex felt great. Like Mark, but different: gentler and more tentative. I was so turned on I was sure I was leaving a huge puddle on Jenny's sheets. She pressed the pink toy against my hungry cunt, and I opened up for her. I was a little afraid that it was going to hurt, but it didn't, not at all. I just felt really full. The buzzing and friction inside my pussy was incredible. I felt a finger brush against my super-sensitive asshole. An accident? I moaned aloud and gave myself over to the pleasure.

When it was over, we rested for a while, just holding hands.

"I liked that." said Jenny. I could still see my come drying on her face.

"Me too" I said

"Does this make us lesbians?"

"I don't think so" I said, thinking of Mark.

"Me either" she said "but I'd like to do that again, if you don't mind."

"I'd like that too." I was thinking about that dildo of hers, and all the things that we could do together.

6.

I snuck out the back door when I heard Mark drop off Valerie at our front door. I knew I was taking a risk, but I was pretty sure I could get away with it. Val probably wouldn't check up on me, and if she did look into my room, I had arranged the pillows so it looked like I was sleeping under the covers. Mom wouldn't be home until 6 a.m. That should leave plenty of time.

I met him at the end of the block. Nobody saw his car pause at the stop sign while I got in.

"Did you have a good date?" I asked

"It was pretty fun. She gave me a handjob. And she let me play with her pussy again."

I felt a little jealous, but not very. He was her boyfriend after all. And I was glad my sister was loosening up. "Did she make you come?"

"Yeah." He laughed "She was kind of grossed out by it."

"Did you save some for me?" I hoped I didn't sound plaintive.

"Oh yeah, don't worry Andrea" he said, and kissed me, "There's plenty left for you."

"Are you going to fuck me tonight?" I asked, only half teasing.

"I can't" he answered. "You know that."

I still didn't understand the distinction he made in his head between getting blowjobs and eating out his girlfriends' sister and actually having sex with her. It didn't matter. I was looking forward to the action anyway.

"You know" I said, trying to sound casual "I heard at school that some people like to do it in the butt."

"Do girls actually like that?" he asked.

"Some of them do" I said, looking up into his eyes "I think."

"Do you want that?" he asked "With me?"

"Yeah" I said "But we should get some lube. You need lots of lube. That's what I heard."

We pulled into a d**gstore, and he came back red faced with a small bag in his hand. There was a little bottle in the bag, full of clear liquid. The label said 'AstroGlide'. I couldn't believe we were actually going to do this.

We went over to his apartment. His roommate was out. We climbed up onto his bed and kissed and made out for a while.

"I want you to fuck Valerie" I said "I want you to show her that sex can be nice."

"Right now" he said "All I want to think about is you."

We kissed and touched for a long time, taking our time undressing each other. I liked it when he played with my nipples. Just having him kiss them made them super sensitive, and sent jolts down to my little clit.

"I want to do everything with you" I said.

"Someday Andrea" he answered "Some day."

"Tonight" I said "I want you to be in my ass."

"Are you sure you want it?" he asked.

"Oh Yeah"

"Are you sure it will fit?"

"I'm sure" I said, trying to sound confident.

"Ok" he said. "Just tell me if it hurts too much."

I climbed on top of him, and we did the 69. I used my mouth to play with his dick, bringing him to rigid excitement. He concentrated on my ass, licking and touching my hole until I thought I would go crazy with anticipation. My little pussy was drooling all over his face. I felt his fingertip invading me back there. It felt good.

"Please, Mark I want your dick."

I crawled off him, and got down on my hands and knees, displayed lewdly like one of the models from Jenny's dirty magazines. Mark got the little bottle out, and as I watched, he spread lubricant all over his cock. I wanted him so badly.

He squirted a bunch of lube onto my asshole. It felt cold, and made me giggle.

"Are you ready?"

"God yes" I answered, wiggling my behind in what I hoped was a sexy way "Please put your penis in my butt"

He knelt behind me, and as I watched, guided his erection between my butt cheeks. When the head of his penis bumped against my anus, a jolt of sexual electricity shot through me. I moaned and closed my eyes, pressing back against him.

At first I didn't think it was going to go in at all. It was like pushing against a brick wall. Suddenly, I felt something let go, and he slipped in.

It hurt. I was scared that I couldn't take it, that my ass would be split open. I felt this huge pressure stretching my butt. I couldn't help but make a little whimper.

"Are you ok?"

"Yeah" I whispered "How much of it is in me?"

"Just the head" he said "Do you want me to take it out?"

"No" I said "Just don't move for a second."

I don't know how long we stayed like that, with the head of his penis buried in my poor little asshole. He patiently stroked my hair as I knelt there, trying to get used to the sensation. I really wanted it; I really didn't want him to have to take it out.

"Try putting a little more in"

He pushed forward, and I felt his dick sliding up my asshole. I realized that it didn't hurt anymore. I just felt incredibly full.

"Try a little more."

He pushed forward a little more, and I pressed back against him. It felt really good. Just a little scary still, like I was right on the brink between pleasure and pain. I didn't want to stop.

It took a long time, but finally I felt his soft pubes against my butt, and he whispered in my ear that he was all the way inside.

"Now fuck me" I commanded him. He started slowly sliding his thing in and out of my ass. The pain had all gone away, and now it was all sweet sweet pleasure. I can't even describe the sensation. Every time he pushed inside me, it seemed like his dick bumped into the back of my clit. I was delirious.

My finger found my clit. It was hard to keep my finger on my button with him thrusting into me, but it didn't matter. Orgasm was washing over me like a tide. It was beautiful. I felt his finger slip inside my cunt as he fucked my ass harder and harder.

"Please come in me Mark" I begged "Please come in my asshole!"

I ground myself back on him as his cock spasmed in my ass. His finger in my pussy sent shockwaves through my body. I loved feeling him come inside me.

We extricated his soft cock from my ass. I felt tender and happy and a little sleepy. We showered together, and then Mark drove me home, with plenty of time before Mom came home.

7.

"Are you fucking my boyfriend?"

I was sitting at my desk, half studying, have daydreaming. My ass was still a little tender from the other night. I was wondering if I could get Jenny to fuck me there with her vibrator. Would that be too weird for her?"

Valerie was standing in my doorway. "Are you sleeping with Mark, Andrea?"

My heart stopped. I had never wanted to hurt Val. "No" I said "But we do… things together."

"What kind of things?"

"We've been fooling around… We have oral sex sometimes, and we've had anal sex." I admitted.
"He did that to you?"

"I asked him to. He wouldn't fuck me. Val, he loves you. It was stupid and we were horny, but he really does love you. Please, be angry at me, not him."

"Dre, you should have told me."

"I'm so sorry."

"It's partly my fault. I should have let him… do things. I just never felt ready."

"I'm really sorry. I don't want to steal your boyfriend. I won't touch him again."

"I need to think about this" Valerie said "I still love you. You're still my sister."

I felt terrible all day. My horny selfish pussy had ruined everything. I couldn't concentrate on school or anything. Jenny asked me what was the matter, but I couldn't even tell her.

Valerie tapped on my door that night. We talked for a long time. She told me about the guy who ****d her, the way her hurt her, and the nightmares afterward. She told me about meeting Mark and falling in love with him even though she was still afraid. We both had a good long cry together. Then she told me.

"I want to have sex with him." Val said "But I'm still afraid to. Will you help me?"

"Of course I will s*s."

"Mark's coming over tonight. Will you be there with me? Will you teach me?"

If Mark was surprised to see both of us when he came over to pick Val up, he didn't show it. He said 'Hi' to me and asked if Valerie was ready to go.

"I thought" said Valerie "that maybe we could just stay in tonight."

"Um, that sounds ok." Mark said, glancing at me.

"All three of us." Valerie said, nodding.

Wordlessly, we made our way to Valerie's room. I found myself lying on the bed with Mark and Val while they kissed. Then Mark kissed me. It felt weird, knowing that Valerie was watching.

"I want to see you naked" Valerie breathed. Mark stripped, and Val and I admired his tight, slender body. His dick was still soft. I think he was unsure what was going to happen. So was I for that matter.

"Show me" Valerie said to me "show me what you do to him."

Self consciously, I started to go down on him. I felt Mark's big dick hardening in my mouth.

"Take off your clothes" Valerie said "I want you to teach me."

I stood up and we stripped together. Valerie has a beautiful body. She has long, shiny black hair like mine, but that is pretty much the only feature we share. We have the same color blue eyes, but hers don't need correction. She is tall for a girl, but not as exceptionally tall as I am. She is curvy in all the right places. I have already mentioned her lovely bust; the rest of her body was just as perfect. Her waist was slender, her tummy nearly flat, her hips were gently curved. She had a full bush of dark pubic hair, shyly disguising her petite labia. I felt awkward and unattractive standing naked next to her.

"Go on" Valerie said "Suck him."

Mark looked from Valerie back to me, and layed down on the bed. His cock was hard and wet and looked delicious. I wasn't sure just what was going on here, but Val nodded encouragingly, so I got back on the bed with Mark and went back to work on his erection. I really got into sucking his dick. I couldn't stop my fingers from straying between my legs where my pussy was hot and slick from the excitement of the situation.

"God" Valerie said "You really like doing that, don't you?"

"Yeah" I said, a little guiltily "I think its fun."

"Don't stop then" she said sitting down on the bed next to Mark "Touch my… vagina the way you did the other day" she said to him.

I sucked gently on the head of Marks penis and stroked him as I watched him touching my sister. Valerie spread her legs and held Marks hand against her pussy. She closed her eyes and rubbed his hand up and down her furry slit.

I was getting really excited, and I could tell Mark was too. I didn't know what was going to happen next, but I was going to have to have an orgasm soon or I would go crazy.

"Mark" Valerie said, sitting up and moving his hand away "I want you to do it to me. I want to have your penis in my vagina. Andrea, will you help me?"

I ran back to my room for the condoms I kept in my underwear drawer. When I came back, Mark and Val were kissing, and she was tentatively stroking his hard cock.

I tore open a package and handed it to Mark. He unrolled the latex down the length of his dick. Valerie lay down on her back on the bed. I sat down and held her hand. She was trembling.

Mark knelt on the bed, his condom-covered penis pointing straight up. "Are you sure you want this Valerie?"

"Yes. I love you Mark." she said spreading her legs. I could see her pussy, and it looked dry and closed up tight like a clam.

"Why don't you lick her a little bit first?" I suggested.

"No" Valerie broke in "Just do it to me."

As I held her hand and stroked her hair, Mark climbed between Valerie's thighs, guiding his cock toward her pussy. She closed her eyes and winced.

"Don't worry" he said "I won't hurt you."

He was rubbing his penis softly up and down her sex. Valerie was holding her breath.

I saw him press gently forward, nosing the tip of his cock into her. Val's eyes flew open. "Stop! No. I'm sorry, I can't. I can't do it."

Mark climbed off and kissed her, grasping her other hand. "It's ok Valerie. It's ok."

"Do Andrea instead" Valerie said "It'll be like doing it to me."

"Are you sure?" I asked.

She nodded "I want this. I want it for me and for you."

I climbed on top of Valerie. Her body felt nice under me, soft and warm. My pussy was drooling; I was so ready for this.

I felt Mark position himself behind me, guiding his cock into my hot, ready entrance.

"I love you Val" he said

"Fuck her Mark" Valerie urged "Do it to her!"

Mark thrust forward, sliding his girth up inside me. It felt heavenly. It was miles better than the dildo. I wiggled around, trying to get more of him inside me. My breasts were pressed up against Valerie's, and that felt nice. "Yes, Fuck me!" I gasped.

Mark started fucking me, sliding his beautiful cock in and out of my hungry pussy. "Oh Valerie" he moaned "She feels so good!"

Underneath me, I could feel Valerie's hand moving, masturbating as her boyfriend fucked me. "Come inside her" she almost snarled "Come in her fucking little cunt!"

"Yeah" I encouraged him "Fuck me hard and come inside me!"

Valerie and I started kissing deeply, sharing tongues in a very unsisterly way. Mark was fucking my cunt hard and fast, and I could feel my orgasm washing over me. I pinched and twisted Valerie's hard nipples as I came, Mark's rampant cock emptying itself into the latex condom deep inside me.

We disentangled ourselves, and Mark threw away the used condom. Valerie's fingers were still busy on her clit. Her pussy was open and drooling. We watched together as she brought herself off.

"Valerie" Mark said, rummaging through his pants pockets "Will you marry me?" He had come up with a small box, and opening it revealed a ring.

"Yes, Oh yes!" Valerie said, tears running down her cheeks "I'd be happy to marry you Mark. I love you so much!"

They embraced and kissed, forgetting me for a minute. I felt a little embarrassed to be there with them at that moment, naked and sticky and still a little horny.

"Maybe" Valerie said, breaking off the kiss "Andrea could teach me about anal sex next."
