Riley’s New Professor Pt3 free porn video

When they woke in the morning they made love one more time, this time tenderly, like lovers are supposed to. They revelled in the luxury of the crisp white sheets, in ordering room service for breakfast, and in just having time together alone.

He noticed how she winced when he touched her backside, and, now his lust had somewhat subsided, almost felt guilty for what he had done to her - especially when he saw her bottom, streaked with red welts, turning to bruises, as she climbed into the bath to soak out her soreness.

He knew that occasionally, at the peak of his lust, he was capable of doing things that he wouldn't dream of in his normal state, and he recognised how much his hormonal, primitive physicality could compromise his reason at these times. He regretted this, mainly because of the implicit risk, but he wouldn't stoop to a base emotion like guilt.

That was the day of his conference lecture, and he was greeted like an old friend by his coterie of academics. Riley had to hang back, but clearly a couple of the other professors noticed her, and she saw one whisper in his ear, looking at her.

She sat at the front of the hall, looking up at him as he spoke at the lectern above her, so proud to belong to him. She enjoyed being uncomfortable on the hard seats as it kept reminding her of their secret.

Afterwards there was a drinks party before they headed home, and she overheard part of a conversation that might have involved her.

"It's your turn to host again this month, old chap, isn't it. I do so enjoy coming to yours, you lay on such a good show.'

'Is your new little friend going to make an appearance? I must say she's not your usual type, I hope you've seen her birth certificate!" The small group of men laughed, but Riley noticed that her man looked distinctly unimpressed, and changed the subject onto their wine.

"Hi."

Riley jumped, and turned to see possibly the most beautiful young man she had ever seen smiling at her and offering her a drink.

"He was, like, amazing today, wasn't he. You are so lucky to actually work with him."

Riley blushed, and mumbled something incoherent.

He was about 21 she guessed, 6 feet tall, lean and tanned, with sparkling blue eyes and a surfer dude vibe. He looked like he should be one of those guys in swim shorts welcoming shoppers at Hollisters.

"I'm coming up to like meet him in a couple weeks, for an interview. Could I, like, get your number, so we could meet up before for a coffee or something?"

"I guess..." She looked nervously over to her man, but he was engrossed in conversation.

"I'm Zac by the way," he said, holding out a strong hand.

"Riley," she said more confidently, taking it, rather won over by his openness and natural smile.

On the train home he had some marking to do, so she tried to get her head into a book. Incidentally Riley had gotten a genuine, well earned, A for her last assignment; somehow she had found more interest in it with his inspiration. Her mind naturally drifted over the events of the last couple days, thinking about how exciting and perfect it all had been.

She leaned over and whispered to him,
"I loved everything that you did to me this weekend. I want you to teach me more and more."

He sort of grunted, but squeezed her thigh before getting back to work.

She suddenly had a thought.
"What were those men talking about? Something about you hosting a meeting?"

He paused what he was doing, and put his pen down.

"That really doesn't concern you, Riley. You shouldn't ask about that." He said looking serious.

"Why not?"

"You're not ready."

Riley looked sulky and used her best puppy eyes.

"You can tell me, I'm a big girl now."

He sat pondering.

"Maybe if there was a way that you could just watch; I'll think about it."

She gave him a hug and a big kiss, and snuggled back down to her book.

After the success of their weekend away he realised that it was about time he had a better space available than his office. He stole the keys to a long forgotten lab in the oldest part of the university buildings, and spent a day at the weekend fixing it up. He smuggled in a few key pieces of equipment, including a mattress, a wooden horse, some bars, and his collection of whips, paddles, sex toys, ropes and restraints, and screwed in some rings and loops at key points.

He had bought most of this stuff for Emily's predecessor but had never got around to making a dedicated space, and looking around he was pretty pleased with his work.

He brought Riley down blindfolded, laid her naked over the horse and tied her wrists and ankles. He ran a small metal spiked wheel from her ankle over her calf, and up the back of her thigh, then repeated with the other leg. She shivered at the intensity of the tingling it produced. He used it on her back, leaving faint tracks that took a few seconds to fade. He then left off her completely; just long enough for her to wonder where he had gone, then without any warning smacked her bottom hard, pulled her hair back, and took off her blindfold.

"Do you like our new playground?"

"Oh Sir, I love it!"

He placed a large vibrator against her slit and held it there, she writhing and moaning as it forced her towards a climax. Sensing that she was about to cum he pulled it away, leaving her groaning, and smacked her hard.

"Please..."

He started it on her pussy again, but as she was about to peak again frustrated her, following up with another smack.

"Please, Sir..."

Again he did it; then again, she now writhing against the straps, desperate to find a way to find release.

"Please Sir..."

"Please Sir what?"

"Please let me cum, I need it so bad."

SMACK

"Badly" he corrected her, "but good girl, I like to hear you begging."

"Oh please...God yes...don't stop...like that...oh Sir, you're so good to me...fuck... Fuck!!!"

She shuddered as her orgasm hit her hard, straining the restraints as her passion pulled against them.

He licked her from the base of her spine to her neck, enjoying the saltiness of her sweat, then kissed her neck as she struggled to turn her head far enough around to kiss him. He relented, and allowed their lips to hungrily meet. He moved in front of her and used his cock on her face, drawing patterns with his precum all over it, before letting her suck his balls, then his cock.

He suddenly, though, was overwhelmed by the need to be properly inside her body, and her tight pussy was all that was going to satisfy him. He moved back behind her and fucked it deeply, watching her pussy lips stretched in and out, his hands gripping her ass as he went over the edge and filled her to overflowing with his cum.

After they both came down he took her on a tour of the room.

"You're really into this stuff, aren't you?" she said.

"I guess?" He shrugged and for the first time ever he looked like a little boy to her.

"Then it's a good job you found me then."

She never ceased to surprise him, but hearing this so sweet and innocent looking girl taking so much so easily in her stride was incredible.



Riley was flying. She felt like she was literally flying.

She was suspended from her arms and legs above the dance floor of a nightclub, with a vibrator held in her pussy by her panties.

She was wearing by far the sexiest ensemble of lingerie she had ever worn; black silk stockings, ludicrously high heels, black lace panties, black corset pushing her small breasts upwards, all set off with a black silk choker necklace, and a mask completely obscuring her face. She was hanging at an angle, in a pose reminiscent of a ski jumper in full flight, her ankles resting against the wall, and straps around her upper arms holding her at 45 degrees.

This was her Prof's idea of allowing her to attend his party, but keeping her safe. Literally out of reach seemed a bit excessive to Riley, but she had no real idea of what the evening might involve.

He had dressed her himself before driving her to the club blindfolded in the back of his car. She had been taken in, tied and the sex toy placed in her without having any idea of where she was, or who was handling her, and her eyes were only uncovered when fully in position high on the wall.

The vibrator was a work of art. It had been a computing post grad's spare time project, and was rabbit style, with a dildo section and an additional prod that sat on her clit. This one however had a chip inserted, connected to a smart watch that measured the wearer's heart rate and temperature and it was programmed to move through cycles of intensity of vibration based on the user's physical state. It could be programmed to bring an orgasm as quickly as possible, or to torment by cutting out after detecting a period of building arousal. The regular user could personalise it for themselves by a calibration process. Each time they had an orgasm they pressed a button, which would allow the software to learn their individual "arousal signature".

It was currently set to a program which was a random cycle of stimulation.

Two men and two girls came in; one of the girls blew a kiss at Riley, and the younger guy said "hey sweetness, you gonna taste some of this later?" as he lewdly grabbed his crotch. They all laughed but then ignored her; the guys dragging a large table into the centre of the floor, the girls taking off all of their clothes, except for stockings and high heels.

The women were both in their mid to late 20s. One had a massive snake tattooed on her back, a full sleeve tattoo, and large breasts with pierced nipples. She had long black hair. The other had fewer tattoos, and very short blonde hair, but looked like a body builder, with powerful thighs, and tightly defined arm and stomach muscles. Her breasts were smaller, but still impressive.

They lay side by side on the table and the older of the two guys skilfully tied them with a complicated arrangement of ropes and knots. One ankle was tied to the other girl's nearest ankle and this rope went through a loop in the ceiling to hoist their inside legs almost to the vertical. The outer legs were folded up against themselves, so the heel of each foot rested on the girl's bottom; held in place by ropes wrapped around thigh and shin. Another rope held their legs wide open, running from the knee to the corner of the table. Each girls' inner forearm was tied to the other girl's, but their outer wrists were tied to the table corner.

Riley couldn’t help staring at their lewdly displayed cunts, noticing that they both had much more prominent lips than hers, and that one girl clearly had some sort of piercing down there as well. She was trying to ignore the insistent vibration in her panties, and most definitely didn’t want to be turned on while looking at girls, but her body was already responding to the stimulation, whether she wanted it to or not.

Music suddenly blared through the speakers, and the room began to fill. About 20 men came in, of various ages. Riley recognised a couple of them from the conference. They were all smartly dressed and Riley guessed that they had come here after a dinner elsewhere. She looked hard to try and see her professor, but couldn't pick him out of the crowd. Each man was accompanied by a young woman, each wearing a tiny cocktail dress. Riley was surprised to see that Emily was one of them, but more so when she recognised another girl, Amber, from her course.

Riley would have said that Amber was the prettiest girl in her year. She was tall and slim, almost too slim, but still with pert little breasts that sat high on her chest. Her outstanding features though, that made everything else irrelevant, were her enormous brown eyes, that beamed with openness and innocence, and seduced anyone who saw her.

She seemed to come from a good background, and Riley imagined her as one of those girls who had a c***dhood sweetheart at home, and who wouldn't dream of being unfaithful to him. What was she doing here?

They all gathered around the central tableau, the men talking appreciatively amongst themselves, and just casually stroking the displayed flesh. A few noticed Riley hanging from the wall behind them and ogled her with delight.

After a few minutes the music stopped and the lights dropped, to be replaced with spotlights fixed on the table. Riley gasped as three men entered the room. They were all naked apart from masks, and leather thongs tied around their biceps and thighs. One had some kind of strap around his cock and balls. It wasn't this that had made Riley gasp though; the man in the middle was a giant. He had to be 6'7" tall, but massively built. There was no sign of any fat on him, just muscle on hard muscle. His cock, though, was what drew every eye in the room, it already looked 9 or 10 inches long, ever though it was still hanging by his thigh, barely aroused. He was carrying a vicious looking whip, and, although his face was partly masked, it was cruel and cold.

His entry coincided with Riley's vibrator suddenly hitting a phase of high intensity, and she found herself cumming for the first time; just a baby cum, but a warning of future events.

The crowd parted as the three men moved to the centre table. The two "normal" men (neither of whom, however, would have looked out of place as underwear models) went between the girl's legs, and the giant went to their heads. He made the girls perform fellatio on the handle of his whip, whilst the other men put their mouths to the two spread cunts.

His cock grew as both girls used their mouths on it, one on the shaft and balls and the other on the head, growing to true massiveness as they got it wet. The other guys used their fingers in combination with their tongues as the girls started to writhe in pleasure.

The giant reached forward taking a breast in each hand, first mauling it, then slapping it. Then he worked on one breast at a time, gathering it up in one hand, and slapping it with the other.

The guys began to fuck the girls. By this time most of the men in the room clearly had erections in their pants, and a couple unselfconsciously had their dicks out, being stroked by their female companions. They gathered around closer, holding a girl's ankle, or teasing a thigh, but keeping well out of the way of the three male performers. The girls' breasts flew up and down their chests as they were pounded. One guy held his slut by the throat as he fucked her, rubbing her clit at the same time; forcing her first cum. The other kept working his woman's breasts, roughly squeezing and slapping them as he ground his pubic bone against her clit.

The giant trailed the length of his whip over the women’s bodies, then, moving to the side, whipped them across their torsos, leaving vivid red welts across their tits and bellies. They screamed, still impaled on relentlessly fucking cocks, and he thrashed them maybe 10 times, before letting the whip drop and pacing around the table inspecting his work.

He face fucked one, then the other, ramming his massive tool into their throats, while the two other men increased their pace, both girls crying out in passion.

The ropes holding them to the table and each other, were released. One of the guys got under the blonde, and she sat on his dick, the other stood behind her and pushed his cock into her ass, slapping it noisily.

The giant fucked the girl with the black hair and tattoos, her pussy lips stretched lewdly around his huge thickness as he rammed it in and out of her. She couldn't take his whole length, and she winced whenever he went too deep.

The two girls kissed each other, then beckoned for more cocks to fill their mouths. Men from the audience moved in, offering their cocks to be sucked and stroked. One of the girls from the audience moved in and sucked on the blonde's nipples, whilst another man lifted her dress, pulled down her panties and fucked her from behind.

Riley was being driven crazy by the view and the vibrator had made her cum over and over again. Her pussy was so wet she feared it might be dripping on the floor below, as she felt herself heading for yet another climax.

The guys swopped around so both girls were being analised on all fours, with monster cock now touring the room looking for girls game enough to try to fit him in their mouths. Emily was the one of the few who did, although most of the girls looked at it hungrily.

Riley was still searching for her professor in the room. She couldn't see him anywhere. Where was he?

For the finale of their scene, the darker girl was spread on her back with the giant fucking her missionary style, while the blonde girl rode his back like a horse, rubbing her breasts on his back. The two other guys squatted on the table over her, fucking the blonde in the ass and mouth.

The three guys then stood back wanking as the girls were re-tied again. They had ropes around their necks like collars, fastening their faces side by side. Their legs dangled off the side of the table, their backs uncomfortably arched as their ankles were tied underneath the table. They each had their breasts tightly bound, the gradual change in colour looking excruciatingly painful.

All the men in the room started gathering around, all with their cocks out, queuing up to cum on the girls’ faces. Some gained extra inspiration from fondling their hard breasts, or fingering their pussies, or slapping their thighs, but one by one, and sometimes two by two, they started unloading thick globs, powerful squirts, or, in some cases, puny dribbles into the two waiting mouths. One let each load drool out of her mouth, but the other let it pool in there until it was full, before blowing bubbles with it, then swallowing the lot.

When just the three male performers were left erect, the girls were untied and one of them, whilst she toyed with the whip, asked the room,

"Do we have any newcomers in the house to be initiated on the altar of sex?"

To her horror, Riley felt herself being lowered to the floor and dragged to the table by the two girls. She was held down and tied on her back, all limbs spreadeagled.

But instead of being stripped or bound further, her vibrator was removed from her sodden hole, and a strap on dildo was fitted, its base plate fitting neatly over her clit, giving her little body an impressive cock.

She couldn't see clearly what was happening around her, but suddenly a terrified Amber appeared in front of her, still in her baby blue cocktail dress, being dragged by the two girls with her arms twisted behind her. They ripped her panties off, and lifted her up over Riley's recumbent form, positioning her over Riley's erect member.

Amber was pleading for them to stop but they inexorably forced her down on Riley's plastic cock, it stretching her wide as it gradually filled her cunt. As it pushed down, the base of the dildo ground onto Riley's clit and, in her hyper-aroused state, she couldn't help responding to the pressure. The girls manually raised Amber up and down on Riley's cock by her arms (still holding them up her back), bringing involuntary moans from her lips, until finally she got the message and started helping them out and they were able to loosen their grip a little. Her pussy betrayed her by coating the black plastic with a glistening sheen of juice.

The three men climbed on the table and started alternately ramming their cocks into Amber's mouth, whilst jerking off hard. They managed to synchronise their cums so three gigantic loads splattered her face almost simultaneously, covering her face and dripping down all over her dress. Amber's writhings to get away ironically only multiplied the stimulations pulsing through her own and Riley's pussies. Each man put their cock into Riley's mouth, forcing her to clean it dry. The raven haired girl licked the cum from Amber's face, and, holding it in her mouth, moved above Riley and let it drip down over her face, before wiping it around and into her mouth.

The spotlights went off, and in a few minutes the lights had gone up, background music started playing, and the bar had opened. The guests chatted convivially amongst themselves. If it wasn't for the preponderance of young girls in too short dresses the casual observer might have thought it a wedding reception or a Bar Mitzvah.

Riley and Amber had been released and taken through to the ladies' toilets. As soon as they were left, Amber collapsed, sobbing, on the floor, as Riley hugged and comforted her. They washed their faces, but Amber's dress was ruined with cum stains, and Riley was naked apart from the ripped stockings and corset.

They decided to make a run for it, and they sprinted for the front door. Bursting through they found themselves in an alley. It was dark, cold, and drizzling with rain. They had no idea of the time, but it sounded like it was well past club closing time as they could just hear a few late night revellers heading home nearby. They crept down the alley to the more brightly lit street nearby.

After a few minutes hiding behind some bins, Riley saw the most welcome sight ever. Zac, whom she had met at the conference, was swaying up the road towards them. She remembered that his interview had been that day, and, with a moment of guilt, that she had stood him up on his coffee invitation. From the look of him his interview hadn't too gone well either.

Riley hissed his name, and in his drunken state he managed to stagger over, his jaw dropping as he took in the mess they presented.

Zac took his coat off and d****d it around Riley; Amber's dress would have to suffice. The sense of emergency seemed to cut through his drunkenness like a shot of adrenaline.

He hailed a taxi, to take them back to Riley's hall of residence. Riley kept on holding the taller girl to her chest, stroking her hair, trying to comfort her, as Amber continued to cry.

When they got back to Riley's room both girls showered while Zac made coffee for them all. The girls sat on Riley's bed, wrapped in dressing gowns and towels, and Zac in a giant bean bag on the floor.

"So what the fuck happened to you two tonight?" Zac asked.

The girls looked at each other wondering whether to tell the truth.

"We were at a party, and things got a bit out of hand." Riley said.

"Uh, what do mean, out of hand?"

"It's okay, nothing, really."

"It didn't look like nothing. Were you guys like. . . assaulted?"

Amber started crying again.

"Should I call the police?" Zac said.

"No! . . . No, that's not necessary." Riley said, "You should go now, we're okay, thank you for everything you did."

He looked really dubious but allowed himself to be escorted out. Riley stretched up to kiss him on the cheek.

"You were amazing tonight, I don't know what we would have done without you."

"If I can do anything..." He looked down at her, his boyish face in an unaccustomed frown.

She kissed him again, this time briefly on the lips.

"You need to go, but we need to meet up, text me in the morning."

Riley sat back down on the bed next to Amber, putting an arm around her.

Amber's hair was still wet from the shower, slick on her slim brown neck and Riley momentarily wondered what it would be like to kiss her there, remembering what it had felt like when their bare flesh was rubbing together. She pushed the thought out of her mind.

"What on earth were you doing there tonight?" she asked.

"I didn't know it would be like that. I got myself into some money problems and I didn't want my parents to know."

Riley dreaded what might come next.

"A girl I know works in a lap dancing club in town, and earns a pile of money. I couldn't possibly do that, but she said I could just go to this party with some old man. She didn't say anything about anything dirty happening at the party, she just said I had to dress pretty and smile at everything the guy said."

Riley didn't say anything, but held Amber tight, absent-mindedly kissing the top of her head. Thankfully it didn't seem to have occurred to Amber to ask Riley the same question.

Riley felt angry and confused. Where was her man? How had he allowed those things to happen? What had she got herself






First thing the next morning Riley stormed into the Professor's office.

"Where were you last night?" she yelled at him, throwing punches at his chest with her small hands.

He held her wrists, restraining her easily.

"I was called away to the hospital. . . my wife. . ."

Riley froze.

"They thought she was having a miscarriage."

Riley didn't know what to say.

"Is she...?"

"She's okay, and the baby's okay. Why what happened?"

Riley collapsed into the chair.

"It doesn't matter. Nothing happened."

"It doesn't look like nothing."

"Amber got hurt."

"Amber? Who's Amber?"

"Fucking Amber from my fucking course!"

"Oh. . . that Amber. . . Is she okay?"

"I don't know..." Riley began to cry.

"I don't know whether I can do this anymore." she said.

He knelt in front of her and took her in his arms, kissing her tenderly.

"I need you, Riley. You can't leave me, not now, you're my muse."

"You bastard, don't. . ."

He kissed again more urgently, tasting the tears on her lips.

She didn't respond, but then couldn't help submitting as she felt his passion for her. But then she pushed him back.

"But what about those girls? Some of them were from Uni."

He shrugged, "They needed cash. They knew what the situation was."

Riley looked dubious.

"I don't think Amber did."

"Then she's a silly bitch, what did she think she was going there for? If I had been there then I could have sorted it if someone was getting out of line."

"So, are you some kind of pimp?"

"Of course not, I resent that. Girls have occasionally come to me with money problems, and sometimes I've pointed them towards something that might help them out, but it's been their choice."

"So what sort of things have you 'pointed them towards'?"

"Oh, just being a hostess really, like Amber last night."

Riley suspected this wasn't completely true after Amber's story about the girl at the lap dancing club, but thought she might keep that to herself for now, although she did want to know how much further he might have gone.

A horrific thought hit him.

"She's not going to the Police is she?"

"No, I think that she was too ashamed, and didn't think they would believe her."

"Nothing like that has ever happened before. I'll sort it out with her somehow."

"So. . ." he said, with a twinkle in his eyes, "what did you think of the show?"

She punched him again, but with less intent this time.

"You bastard."

"You know it and that's why you love me. So?"

"It was really hot, the guys there were just, like, wow!"

He started teasing her by kissing her neck.

"What did they do that turned you on?"

"They fucked one of the girls in all her holes at once."

"Mmmmm, that does sound sexy." He dropped his head and found her nipple through her t-shirt. "Would you like that one day?"

She laughed and pushed him away, "You are a complete bastard, you know. I need to go, I have a lecture."

"That reminds me, I have something I've been meaning to give you."

He went to his desk and got out a small box, wrapped in shiny black paper, with a red ribbon and bow.

"Open this in the morning, and follow the instructions." he said. "It's time to start your training."

Riley frowned at him, but popped the box in her bag, and left, indulging him with a little kiss on the cheek as she went.

She didn't actually have a lecture, but had arranged to meet Zac at one of the campus coffee shops. As she walked she wondered how she had let the Prof get around her so easily, but felt a little buzz that she had lied to him for the first time and had a secret assignation.

In future years she often wondered whether indeed this had been the turning point; if she hadn't let him off the hook so easily on that day, if she hadn't met with Zac, would everything had worked out differently? Was that the last day she could have walked away? When she was feeling less good about herself she beat herself up for not having had the determination to challenge him more, forgetting how young she had been, and how much in love.

Zac gave her a hug and a peck on the cheek as they met, and he bought their coffees. Neither of them brought up the night before, although he did ask whether Amber was okay. They chatted about their work. Zac confirmed that he hadn't got the PhD place, but he was going to be around the campus doing a research assistant internship. He was curious about the Prof. but Riley avoided the subject.

Riley noticed Emily working alone on her laptop in a quiet corner of the coffee shop, wearing her Thai Boxing Society sweatshirt, and black Lycra leggings showing off her long slim legs, but they barely acknowledged each other. Riley again noticed how beautiful Zac was, but appraised him only in a detached, objective way, as she would another girl. In a strange way he reminded her of her younger brother. They seemed to get on really well, he was easy to talk to and they had a lot in common.

Chapter 2 Anal Training

It wasn't until the next morning that she remembered the Prof's present. She unwrapped it and opened the box to find a tube of lube and what looked at first like a small dildo. She puzzled over its shape. It gradually thickened from a point at one end, reaching maximum circumference about three quarters along, before quickly tapering again, but this end was topped by a larger rectangular flat base.

The instructions said "Wear this all day. When you're wearing this (and only when you're wearing this), you must wear a skirt."

She knew she had seen something like it before, but wasn't sure what it was for.

Riley reached for her laptop and pulled up a website for a sex shop. She quickly found what she was looking for.

She was curious, and wanted to try it out right away.

She went to the bathroom, where there was a full length mirror she could use. She took off her panties and kneeled, sticking her ass out towards the mirror. She looked at her tiny pink puckered asshole and rubbed some lube into it before starting to push the tip of her toy against it. At first it resisted, and just kept slipping away to one side or another. She gave herself a good talking to, reminding herself that it must open wider than that every day, and concentrated on relaxing her muscles. This time, as she pushed, her anus gradually opened around it, and she kept pushing until it passed the middle, at which point it slowly pulled itself in to the base.

Riley admired it inside her, and twisted it so the base aligned with her bum crack. She explored the feeling - it was intriguing; she felt full, but in a new way. She stuck her ass way up, and, still watching herself in the mirror, played with her pussy and clit, as with the other hand she turned and pulled the butt plug, feeling the resistance as her sphincter held onto it.

She knew that her lover wanted to fuck her in there, and, having now seen other girls take it, she wanted it too; to become a complete woman. It excited her to realise that she had another virginity to offer her man. She put on her shortest skirt and went off to her lecture.

He had always ignored her in lectures, but today Riley saw a glint in his eye as he took in her skirt. She made a point of sitting in the front row and parting her legs under the desk. He wouldn't be able to see anything, but he would have noticed the gap between her knees. It felt so weird to have something in her bottom, the base being agitated by the seat so she was continually aware of it.

At the end of the lecture he asked her to stay behind. As everyone filed out he said,

"I take it that you have started your homework."

Riley smiled coyly and nodded.

"Show me." he said.

"I can't! Someone's gonna walk in!"

"I know, come and look out the window."

One of the windows was towards the corner of the room, not quite in view of the door, so they would have at most a second or two if anyone came into the lecture theatre.

Riley leaned her forearms on the windowsill and watched the hundreds of students walking past, just a few metres away, as they moved between lectures. He lifted her skirt up and pulled her panties down to the top of her thighs. He found her butt plug, and toyed with it, like Riley had earlier, testing how her sphincter resisted him pulling it out.

He did though; pulling it out to the point where the tip was still just inside, before squeezing it back in, dilating it to the maximum as it past the mid point, then it contracting tightly as it pulled the rest in.

"You do realise that that is just the smallest size?" he said.

Riley nodded.

"I think you are going to need quite a bit of work before you are able to take me in there. It would really hurt at the moment... but maybe you'd like that?"

Riley shook her head as he continued to move it, each time taking it out to just before the mid point, then watching in fascination as her ass slowly pulled it back in. She tried to look more relaxed as she noticed someone looking at her curiously from outside.

"I want you to be wearing that tonight. Meet me at my office, we need to play some more."

There was a crash behind them as the next group of students came piling into the room, chatting loudly. He instantly dropped her skirt and turned from her.

"Come in, settle down as quickly as you can, we have a lot to do today."

Riley snuck out, feeling every eye in the room on her; aware that her panties were still below her bottom, and praying that the plug wouldn't fall out.

That evening he played properly with pulling it in and out, licking her empty hole as it popped out, and substituting his finger. He thoroughly lubricated her ass hole, enabling the plug to move in and out more rapidly, and got her to the point where sometimes, if he pulled it out quickly enough, it would stay gaped for a split second before closing up again.

They left it in her while they fucked. He reached around at the last minute to discard the plug and replace it with his index finger. He was able to push it all the way in, way more than she'd ever been able to take before. She came so hard from feeling him possessing her so deeply, and he from the sensation of being squeezed so tightly- his finger and cock alike.

A couple days later a parcel arrived at her halls. Thankfully she recognised the shape of the box, so didn't open it in front of anyone. Her new plug was about 50% larger than her first, and she relished sucking it, before lubricating it properly and putting it in her ass. She had learnt by now how to put it in, but, as it entered her, she could feel the extra size challenging her poor tight asshole to the limit.

She took it out again, and assessed it. She estimated that it was still a bit slimmer than the Prof's cock, and nothing like as long, but she knew that she wanted it to still be a challenge when he first put it in there, so thought that this may be her last size before she offered herself to him.

Riley thought that she had better make a good job of getting used to this one first - and quickly, as her hunger to take him was growing. She wore it all that day.

They had booked a motel room for their next meet up. He was disappointed when she turned up in jeans, but when they were naked on the bed, with her licking and teasing his cock with her mouth, she looked up at him and said,

"I'm ready for it, I want you to fuck me in the ass tonight. I can't wait any longer, I don't care if it hurts."

His cock showed its approval by growing harder as spoke, throbbing impatiently.

They took it slowly, holding themselves back from the main event. She continued her blowjob, but he turned her around so that he could lick her pussy at the same time, and although focussing there, every so often he reached further to explore her ass a little with his tongue.

He fucked her missionary style, bringing her to successive orgasms; holding her tightly as she cried out, and kissing tenderly as she subsided.

He flipped her over and inserted his index finger in her asshole. It looked tiny, but he noticed how much more easily it slipped in. He lubricated his fingers, and this time squeezed two fingers in there.

She smiled back at him happily, lifting her ass further, and biting her lip at the new sensations inside her, his fingers feeling real and moving around so much more than the plugs had. She brought her fingers to her clit, out of a mixture of lust and a wish for a distracting sensation.

Then it was time. She rubbed some lube over his cock, which only succeeded in making it look even more swollen and angry, and he positioned its fat head at her entrance. He started pushing gently but got nowhere, Riley had tensed up despite her good intentions. She took a deep breath and concentrated on relaxing as he pushed harder. His glans was gradually swallowed up, and once it had passed her sphincter progress became easier.

It was still incredibly tight though, he had felt nothing like it before and she felt much more stretched than she had by the plugs. She worried for a moment that he would split her, but then it started sinking in further with his insistent pressure until she had taken maybe half of it. She kept working her clit as he began to move it back and forward. The sensations were new, but she could feel the pleasure alongside the pain, especially as she added the feelings from her clit.

He looked down admiring the smallness of her butt, making his cock look even more massive in her. He gradually increased the pace, aware of the need to be gentle, but unable to control his passion. Bit by bit more disappeared into her, although there was no way he was going to get all of his cock in her.

Riley focussed on the feelings coming from her ass; it felt different to him being in her pussy, but it was certainly giving her lots of sensory stimulation, which, paired with her hand on her pussy, made for a sexual high. The biggest turn on though was the knowledge that she was taking her man in her most private place, somewhere she wouldn't dreamt of letting anyone go just a few weeks before. It was special, a something more that she could give, a virginity more exclusive and rare, as much as it was lewd and pornographic.

As he raised the pace she pushed her ass back to meet his strokes. She put two fingers in her pussy, feeling his cock's motion through its walls. She came hard, feeling so full, so fucked, so loving.

She felt, or imagined she felt, the splatter of his cum into her bowels, spraying her insides, as he moaned in ecstasy, holding her ass against him. They collapsed together, holding each other tight. Her ass felt bereft; stretched and empty now, but she looked forward to the soreness that she guessed would follow, as a reminder of her achievement.


Chapter 3 The Prof. Exerts His Control

The next time something was different. He was reserved, preoccupied, almost sulky, and he wanted to meet in his special room.

He tied her face down on the wooden horse, and spanked her thoroughly, before fucking her hard. He was rough with her breasts, reaching around and digging his fingers into them as her fucked her from behind. He took her ass again, but without care, making her squeal, and screw her face up in pain. He made it gape with his fingers, before dribbling his spit into it, rubbing it in, then ramming his dick back in.

She was left sore, weak, and shaky, like she'd been through the wringer and hung out to dry, and although he was gentle and loving with her after he came, she wasn't sure whether she had done something wrong.

A few days later she unexpectedly got a text from him at midnight.

"Come outside, I have something for you."

She pulled some clothes on and went downstairs. He was waiting outside in his black Range Rover. He gestured for her to get in the back, where she was concealed by privacy glass, and he drove off towards town.

"I have a present for you to play with tonight. Put on the blindfold." he said, and she complied.

After around 10 minutes driving, they parked and he led her out of the car, into the cold, and then into a warm building. She thought she recognised the smell of stale perfume, alcohol and sweat, and she could hear the bass beat of some muffled music.

He tied a gag in her mouth, apologising, "I'm sorry for this, but you'll understand why you mustn't speak in a few minutes. I suspect that you will want to use your mouth though, so hopefully it won't have to stay."

He led her into another room, where the music was blaring, and when he removed the blindfold it took a few moments for her eyes to become accustomed to the light. She couldn't believe what she saw.

She was back in the nightclub where the party had been. In the centre of the room, where the table had been, was a single figure illuminated by spotlights, his hands tied above his head by a rope from the ceiling. His lean body was completely naked, except that his head was hooded. His torso had red marks around his rib cage.

Emily was standing in the shadows grinning at Riley's shocked face. She was wearing gym kit; tight Lycra shorts and a skin tight vest top, showing off her bare midriff.

Riley's shock doubled when she realised who the man was, it was Zac.

The music provided an effective aural mask, and the Prof, taking Riley by the arm, said in her ear,

"I heard that you had found yourself a little boyfriend and thought that we should all get better acquainted.'

'Perhaps I haven't explained this properly to you, but you need to understand that you can't see anyone else whilst we are together.'

'As you didn't know I won't punish you, but it won't happen again. You can even play with him if you want, but it looks like Emily has got there first."

With that Emily stepped in and put a powerful roundhouse kick just under his ribs, using the full power of her long legs. He yelped and groaned, and sank a little on the ropes.

"Emily has been looking for some extra Thai boxing training. So much more motivating than a punchbag don't you think?"

Riley pleaded with him with her eyes.

"Oh, you want her to stop?"

Riley nodded desperately.

"Ok. Well I promised you a present, so here's the deal.'

"I love you, so I will give you one more time with him. To stop me feeling too jealous Emily will look after me as you do him. If you can make him cum before I cum then we will let him go and never bother him again. If you can't then Emily can have him all night, which will probably mean he will leave here without any balls the way she kicks.'

He looked at Zac appraisingly.

'To be honest if I'm not man enough to last longer than that k**, then I should let her kick me in the balls. Although from the look of him he's not exactly feeling horny. You might have quite a challenge. This could be interesting.'

'Can I trust you if I take the gag out?" She nodded, and he removed it.

"Don't make me do this, please. He's not my boyfriend, I haven't done anything with him!"

"Hmmm, but he's here now, and all tied up. We can't waste that. You need to show me you know how to have some fun, and will do as you're told." he said stroking her face lovingly.

Riley felt frozen, but found herself nodding.

"Good girl, I knew you wouldn't let me down."

Emily strutted over to the Prof, and started rubbing his cock though his pants.

"Looks like you better get started. For obvious reasons you're not allowed to speak to him." he said.

Riley walked over to Zac and evaluated the challenge in front of her. He looked beaten, physical and mentally. He was supporting his weight solidly enough, but it was obvious that he was just waiting for the next blow, with no way of knowing when it was coming. His cock was shrunken, and his large balls were doing their best to withdraw back into his body.

Scared for him, she kneeled in front of him, and stroked the back of his thighs, which were covered in short wiry blond hairs. He tensed and tried to twist away. She persevered, moving her hands to his smooth, muscular butt, and suckling his limp cock into her mouth.

He stopped trying to get away, but probably more out of fear for his dick than anything.

She tried everything she could think of; taking it all in her mouth, and reaching her tongue out to lick his balls; trying to use suction to stretch it; giving his balls a tongue bath, licking and teasing the head of his cock, but nothing was working. She even tried slipping a finger around his anus, but he twisted away.

She paused to puzzle over how to let him know that her intentions were friendly.

She took her t-shirt and bra off, and hugged him, just hugged him like a friend, feeling the Prof and Emily's eyes potentially boring into the the back of her head to check she didn't speak to him. She felt him initially tense, but then relax slightly, and she then began to rub her breasts over his chest and back. She held him from behind, one arm around his chest, her nipples teasing his back, the other hand on his cock. At last she felt some response, his cock showing some signs of life.

She moved back in front of him again, on her knees, and took him in her mouth. At last! As she worked her mouth up and down it started swelling, until she could start using her hand on the shaft as well as her mouth on his head. She teased his balls with her fingers.

The tension in his thighs and ass returned, but not from fear this time, but arousal. She said a silent prayer to Zac - "Just let go!"

She held his butt cheeks in both hands as she sucked the best she knew, working it in deep, and keeping suction as she moved out, then plunging back down again, using her tongue on the underside, playing with his balls all the time.

She worked him frantically, desperate for him to cum.
Suddenly she felt her pants being ripped down, her ass lifted and a cock being forced into her non-too-turned-on pussy.

She looked back to see the Professor fucking her, a lewd smile on his face, as Emily cuddled him from behind.

"Same rules." he mouthed at her, and increased his pace, her pussy responding despite herself. Emily slid on her back between his legs and licked his balls as they slapped on Riley's clit, then moved in further to lick his shaft at the point it was disappearing into her. Her tongue kept stroking Riley's pussy, either deliberately or not, and the sensations were impossible to ignore.

"I can't hold out much longer." he teased, but keeping long slow strokes to give Emily's tongue full access.

In desperation Riley took her mouth off Zac, instead using both hands vigorously on his shaft, jerking him as hard as she was able. Just as she was about to give up, he suddenly grunted and cum started spurting from his cock; big heavy globs of thick white cum. The first shot flew way over Riley's head, and splattered down her back, the second hit her square in the face, the third in her chest, and the rest she managed to keep away from her.

Emily moved rapidly around, and took Zac's cock in her mouth, catching the last drops, then licked it off Riley's face as she continued to be pounded from behind. With her lips still covered in cum Emily forced a bruising kiss onto Riley's mouth, pushing her tongue over her teeth.

She then moved back to minister to the Prof. who came into Riley almost the moment Emily grasped his balls.

He fell back from her, his still hard cock slapping back on his tummy. He hugged her around the neck, and whispered in her ear,

"That was awesome, babe, you did so well. I knew I could rely on you. Let's get out of here, Em will tidy up."

In the car back he seemed buoyant. He promised that he had just been messing with her, that they wouldn't have hurt Zac, and that he'd probably be home by now.

Riley wasn't so happy. Yet again he'd made her do exactly what he had wanted. This time she hadn't enjoyed it. He had demonstrated that she was more under his power than she had known, and less able to walk away. What did he have next in mind for her?

When his car arrived back at her hall, she didn't get out but sat quietly.

"Sir. . ." she started hesitantly, "I didn't really like what happened tonight, it scared me."

He looked at her thoughtfully, admiring her bravery.

"You weren't really supposed to enjoy it, it was to teach you a lesson. But I was proud of how well you dealt with it."

"I do love you, you're different to any of the girls I've had in training before, which makes you precious to me. I would never do anything to you that I thought you couldn't handle, but if you are to fulfil your potential then I do need to push you - to keep you at the edge of your comfort zone, and sometimes to push you over the edge, and you've already demonstrated how well you can handle that."

He thought back to the incredibly sweet and naive girl he had first met, such a short time ago, what enormous steps she had taken, and how she had taken everything he could throw at her in her stride (until possibly tonight).

"You have so much potential, there is still so much I can teach you. If you give yourself up to someone completely the rewards are immeasurable.'

"You can walk away anytime you want, but while you're with me you have to play by my rules, do everything I say without question. I suspect that if you were to walk away you would feel a big hole in your life, that maybe you would never manage to fill again."

Riley sat in silence, pondering.

She turned him and kissed him.

"Sir, I still want to be yours. I love you too, and want you to teach me everything you know."

He laughed, "Now that would take a while."

They kissed again, she thought about asking him to stay the night, as she wanted to be held, but decided against it and went up to her room.

She saw Zac in passing in the morning, he looked fine.

"Hey Zac, everything okay?"

"You bet, babe, I met this girl last night; she started out a bit weird and kinky, it was like, oh my god, what have I got myself into, but then we went back to hers and it was, like, awesome, it was the best ever."

Riley smiled, so Emily had looked after him after all.
