Taking Control Part 3 |

Homework

That Friday at lectures, Ava told Lorenzo she wouldn’t be coming round that weekend. She was staying in to do some reading and research. He’d looked at her knowingly and smiled, kissing her hand.

Back at home in her own small apartment, Ava’s thoughts were still in wild confusion. It was one day on from the powerful spanking session that had been so surprising and yet incredibly erotic and freeing. Stripping out of her shorts and camisole, she padded over to the fulllength mirror to look at her naked rear. Twisting her lithe body round, she was shocked at the sight that confronted her. Livid streaks and deep purple bruising combined with deep red lines, spread all over her battered behind. She carefully massaged in the special bruise liniment she’d bought over what was a clear livid handprint on her right buttock, blushing when she remembered the curious look from the pharmacist over her explanation.

She bent forward, peering down with trepidation between her legs, opening her smooth pussy up gently with the tip of a long manicured finger. Her vulva was still puffy and delicate to the touch where he’d caught her several times with his palm during the brutal spanking she’d endured. She prodded herself either side. It felt like soft veal which had been smacked roughly with a tenderiser. She mused that she looked like a vertical version of her friend Shania’s botoxed lips, their current colour not dissimilar either. Her delicate labia, normally tightly and tidily tucked inside her , protruded slightly, still swollen. 

Just 24 hours ago she had experienced exquisite pain, as well a ual high she’d thought almost impossible. The question was, what would happen next between her and Lorenzo? And what did she really want from this relationship? She decided she really had to fully understand what might be in store for them both in the future. In the kitchen she poured herself a glass of red wine, came back in the lounge and, given the hiding she had endured, found a soft chair that was just comfortable enough to sit in. From her bag she took out the book he had given her, determined to study what life was really all about as slave and master. She began to read, taking time to go over the many things about this ‘BDSM’ term that perplexed her and, as yet, made little sense within the confines of the previous safe world she’d known.

“BDSM covers a wide range of activities that, to most people, sound complex and pretty far outside the ordinary but, in reality, are not anything like as extraordinary as you might first think.”

“There is considerable interest in the types of ual activity called BDSM. You only have to look at the success of novels and movies such as’ The of O’ and ‘Fifty Shades of Grey’, together with films such as ‘Nine and a Half Weeks’, not to mention Marlon Brando’s ‘butter’ scene in ‘Last Tango in Paris’, to recognise we like the idea of BDSM.”

“Recent research shows 65% of women and 53% of men have fantasies about being dominated ually. When you ask them if they want things the other way round, 47% of women and 60% of men say they want to dominate someone else ually.”

Well, that was a good start. So, liking BDSM didn’t automatically make her a pervert. But what about people who actually did it? She turned quickly to the chapter on the science of BDSM.

 “When researchers ask men and women if they recently engaged in BDSM activities, only 2% say that they have. This percentage has stayed relatively consistent for the last twenty years.”

“So, both the conclusion, as the success of the numerous novels and movies proves, is that most men and women spend a lot of time fantasising about BDSM, yet very few of them have the courage to take it any further or indulge in it with their ual partners.”

“Of course, you could conclude that the research is plain wrong, and that people either don’t understand what BDSM means, or they don’t want to admit doing it, if it paints them in a bad light socially.”

“And that’s really the crux of the public perception of BDSM. Most people have seen or read about it, most people like the sound of it, most people do fantasise about it, but noone really wants to talk about it or admit they do it.”

Well, there it was, out in the open. Ava had loved reading steamy novels about being dominated ually by a man, but no one had ever tried BDSM with her, let alone ask if she was interested in it. Maybe she’d just not yet met the right man?

“So, let’s look at how BDSM came about, and what it actually is. Individuals and couples have been interested in it and intrigued by it since the 1960s, even if they do haven’t gone as far as to act out the roles of master and slave in the bedroom, or as subordinate and dominant in their ual activities.”

“The BDSM term is an abbreviation for three distinct related word pairs. BD refers to bondage and discipline, DS to dominance and submission and SM to sadism and masochism. Each are, in effect, three very different parts of the BDSM spectrum.”

Ava reflected. So, what they’d done last night was a heady mix of discipline, dominance, submission, sadism and masochism. In fact the only bit they hadn’t engaged in was the bondage. But then if you counted Lorenzo holding her down hard over his lap with his hand, while he spanked her, maybe they’d completed the whole set. That worried her slightly. How did he know so much about all this?

“There are various terms broadly used in BDSM as a social, psychological and ual identity, as well as indicating a man or woman’s usual preference during their ual activity.”

 “The terms ‘top’, ‘bottom’, or ‘switch’, for example, are often used to describe the roles of a couple and their specific interests for the duration of a single ual act. The same terms are used in BDSM with slightly different meanings. But, in both contexts, the term ‘top’ refers to the person who is taking the dominant or active role, and ‘bottom’ as the person taking the submissive or passive roles, not who is physically on top in any particular ual act.”

Ava realised the deep feelings she’d experienced, around those two stunning orgasms during their exotic activities last night, were wrapped up in her mentally accepting Lorenzo as a dominant.

“From the 1970s onwards, people would often identify their particular BDSM interests by wearing a set of keys on the side of their belt or a colourcoded handkerchief in their rear pocket. This practice was called flagging, indicating their ual preferences, and whether they preferred top or bottom. There is considerable controversy about exactly how many tops and bottoms there are amongst male and female and straight and gay populations. This is because very few people, even today, are willing to admit to others that they know to taking part in these types of ual activity.”

She thought of her small group of close college girlfriends again. The idea of any of them engaging in BDSM made her smile. But then, they probably imagined exactly the same of her about BDSM.

“Researchers and practitioners have developed categories of BDSM activities. Physical restriction (bondage, handcuffs, rope, chains, suspension), administration of pain (spanking, caning, clothes pegs on the skin, screwclamps), humiliation (gags, verbal humiliation, kneeling, cleaning) as well as a category related to ual behaviour.”

Ava wondered what weirdos were into cleaning humiliation. Surely noone wanted to clean things if they didn’t have to? But then she chided herself. BDSM seemed to be about new experiences and experimentation. So, heyho, each to their own she shrugged.

“In BDSM, there are generally two roles. One partner is dominant and the other is subordinate. These are commonly known as top and bottom, or dom and sub, or master and slave. Top can mean either a dominant partner in BDSM play (such as flogging, binding, being master or other ual play including penetrating the orifices of another partner), or a partner who applies stimulation to the other, and who may or may not be dominant. BDSM clothing can also help to emphasis the respective roles that each partner is playing.”

This was all a hell of a lot to try and get your head round, as well as trying to work out which permutations of all the dominant and submissive roles she read about she thought she might best fit into.

“The term ‘versatile’ is sometimes used to refer to someone who plays both top and bottom roles at the same time. This versatile term is usually used to avoid confusion with the word ‘switch’, which is another name for a light cane in BDSM spanking.”

Ava moved the soft cushion beneath her bum. Spanking. Well Ava knew all about that BDSM activity only too well. But a ‘versatile’ role? Now that sounded very interesting for both of them, being flexible about who was dom and who was sub, all in one session. 

“A related BDSM term, ’topping from the bottom’, means a person who simultaneously adopts the role of bottom and dom. A ‘service top’ is a person who applies sensation or control to a bottom, but does so at the bottom’s explicit instruction.”

Ava paused and started to laugh, images of ridiculous clothes and ual positions tumbling through her head. But she liked the idea of a service top. Lorenzo asking her to do something ual to him, yet Lorenzo would still remain in charge, still be her master.

 “In BDSM, bottom can mean either a submissive partner in ual play (such as being gagged, tied, humiliated, or made to serve), or a partner who receives stimulation from another, and who may or may not be submissive. A bottom in BDSM does not have to be the receptive partner. For example, a female dominant may command her submissive to penetrate her.”

Interesting. So, she could ask him to do specific things to her, but she would still be the one actually in control. She rather liked that. She thought how great it would be to switch their roles round. Him to tie her up but her to command when and how to penetrate her.

Ava’s eyes shone. This was incredibly exciting and liberating. Given her limited experience, a ual past with what she could only regard as relatively unadventurous men, these were things she’d never remotely thought about before. A scenario came into her mind, one where she was standing there completely naked, but he was kneeling on the ground, in front of her, handcuffed and with a collar around his neck. Lorenzo licking her out, at her command.

“On a physical level, BDSM is commonly misconceived to be all about pain. However, most often BDSM practices are primarily concerned with power, humiliation and pleasure. Of the three categories of BDSM, only sadism and masochism specifically requires pain, but this is usually a means to an end, as a way to create feelings of humiliation and dominance. The aspects of dominance and submission and bondage and discipline may not include physical suffering at all, but include the sensations experienced by different emotions of the mind.”

So that was what had happened last night. Lorenzo was clearly into sadomasochism. And yet making her feel pain had also led to her own exquisite pleasure, when he took her over the dining chair. Physical pain leading to physical and emotional pleasure. Delightful.

“Dominance and submission of power is an entirely different experience, not always psychologically associated with physical pain. Many BDSM activities do not involve any kind of pain or humiliation, but just the exchange of power and control. During these activities, practitioners can feel endorphins comparable to the socalled ‘runner’s high’, or to the afterglow of an orgasm. The corresponding trancelike mental state is also known as ‘subspace’ for the submissive, or ‘topspace’ for the dominant.”

“Some use the term ‘body stress’ to describe this highly important physiological sensation, an experience called algolagnia. But this is not the only motivation for many BDSM practitioners. The philosopher Edmund Burke defines this sensation of pleasure derived from pain by the word ‘sublime’.

It made sense. That euphoric high she’d felt, before blacking out.

 “To test this theory in psychological terms, researchers studied randomly assigned ‘switches’ to be top or the bottom in a scene.”

“The results revealed that both bottoms and tops entered altered states of consciousness, but different altered states. Bottoms entered an altered state called ‘transient hypofrontality’, associated with reductions in pain, feelings of floating, feelings of peacefulness, feelings of living in the here and now and even time distortions.”

So that was it then, why she’d felt such highs during her orgasms. Something so outside of herself, otherworldly, it defied description.

“Tops, in contrast, entered the altered state known as ‘flow’ associated with focused attention on optimal performance of a task and a loss of selfconsciousness. These pleasurable, but subtly different altered states of consciousness, are likely to be one of the motivations most people have for engaging in BDSM activities.”

“Research has shown that couples engaging in consensual BDSM also tend to show hormonal changes over time that indicate decreases in stress and increases in their emotional bonding.”

“Perhaps surprisingly, shortterm bruising aside, BDSM is also good for your health. BDSM practitioners have lower levels of depression, anxiety, posttraumatic stress disorder, psychological sadism and masochism, borderline pathology, and paranoia.”

“When looking at the effects of BDSM on personality traits, practitioners exhibited higher levels of extraversion, openness to new experiences, conscientiousness, and subjective wellbeing. They also showed lower levels of neuroticism and rejection sensitivity.”

So, rather than being a perversion, something she’d thought reviled by society, BDSM activities could be a factor that bonded them both together, something strong and healthy between them.

 “The negative traits that emerged were that BDSM practitioners showed higher levels of dissociation and narcissism, as well as lower levels of agreeableness than nonpractitioners. That is to say, they like themselves, are confident people, but also like to be in control.”

“This may be why there is a marked higher proportion of BDSM practitioners in professional and whitecollar roles, as opposed to bluecollar and unskilled roles. There is also a suggestion, as yet untested, that there is a link with BDSM and higher intelligence.”

OK, so that gelled with Ava. If a lot about BDSM was linked to wanting to be in control, then it was bound to appeal to those people who already had relative positions of power.

She guessed a lot more people engaged in BDSM activities than she’d imagined, but few wanted to admit it, especially professional men and women professionals. Next time she walked round college, she would look at other people in a very different light.

It was three in the morning when she finally put the book down, astounded at the prospect of some of the exciting and potentially frightening ual activities that lay ahead for them, desperate to tell Lorenzo all about her thoughts, at early Monday lectures.

The next morning, she woke late. As she reached over on her bedside table for her watch, she spotted a missed call from Lorenzo on her mobile phone. Smiling, she switched her phone off. It would do him a bit of good to wonder exactly what was going to happen next, just like she’d had to, standing there naked in his apartment.

Her bum felt tender, but a lot better. Some of the swelling had gone down, to be replaced with huge purple bruises where he’d smacked her wickedly with his hand, and tiny thin stripes where his nails had caught her sensitive skin. If she was going to let him do that to her again, then he was going to have to cut his fingernails.

She replayed back what she’d just been thinking. This was it then. Her reading until early in the morning had clearly cemented the conclusions she’d already come to. Sleeping on it all hadn’t changed her mind either. She wanted to see where BDSM took her.

Every way she looked at it, she wanted it. In fact, it was more than that. What Lorenzo had made her experience went beyond a simple rational decision; it had been a truly lifechanging experience.

But, if she was going to embrace this, and all of what the BDSM world that might lay in front of her entailed, she was going to prepare for it as thoroughly as she could. And that meant getting to understand it as much as possible, from all perspectives. She also thought about her bum, still smarting with residual pain. She’d need to work out what do about some of the obvious physical marks certain BDSM activities entailed. Marks on her bum were one thing, but if she had chafe marks on her wrists, people were bound to see.

She cooked some scrambled eggs, taking the plate and a slice of toast over to the desk. She put a soft cushion on her chair, settling in under the table carefully. Her laptop was in front of her. Time for some internet searching. She opened up a private browser window to hide her hi, just in case someone happened to see her laptop in lectures. Entering ‘BDSM play’, her eyes went wide.

It was an even bigger new world that opened up to Ava. Even Wikipedia had its own detailed page all about it, and there was no shortage of advice and opinions about what, how, when and who should do what, and to who. Some of the activities people engaged in looked downright dangerous. Putting a cord around your neck to cut off some of your air, to give you a more intense orgasm, looked like an accident waiting to happen. In fact she remembered something about that. Yep, a rock star and a British Member of Parliament had both died that way. Ava was willing to bet that those two people made interesting headlines. Or maybe there were lots more that happened, that got hushed up, never made the papers.

By the time she’d covered all of the main BDSM topics she’d listed from reading Lorenzo’s book that intrigued her, it was past lunchtime. She made herself a sandwich and sat by the window, the afternoon sunshine illuminating some of her darker thoughts.

None of this BDSM stuff was simple and it just didn’t seem quite normal. Liking and wanting it still made her feel a bit of a pervert. But she realised that what she particularly liked about BDSM was it meant. That, for a short time, nothing was her decision, that someone else was in complete and utter control of what happened.

Every day she spent her time having to organise things, get up, make sure she was at lectures, read study topics in the library, do assignment work, go out with friends. With BDSM, as a submissive, she didn’t have to plan or think about anything other than what was occurring to her body, at that very moment. Submitting yourself to someone else’s will was allimmersive and encompassing. And, when you trusted your partner, it made you feel safe too.

And, from what she’d read and seen online, it was clear there were millions of people out there engaging in it. Tens of thousands of people contributing their views on every nuance of BDSN online, and yet noone around her was willing to admit they indulged in it.

She remembered what Lorenzo had said. All those city girls and their parents, secret cupboards and hidden shelves stuffed with special equipment. She guessed it was a bit like when your doctor asked you how much you drank. You nearly always said what was the medically acceptable limit for drink, rather than the truth, which was that you drank at least double that. Everybody knew someone who drank, but noone wanted to admit they might be at risk of becoming an alcoholic. The same with driving too fast. She knew loads of people who broke the speed limit, but their reply to any policeman stopping them would always be that they were only going the maximum speed for that area.

Maybe everyone was just naturally a hypocrite. Because BDSM was unacceptable to normal society, then you couldn’t talk about it? Let’s face it, most people said they did only what society expected of them. So, what exactly did people think it said if they admitted they liked bondage and spanking?

That was what was strange about BDSM. Having experienced just small aspects of it, she knew it was both enticing and exciting, and not just the ual aspects. It was the ‘good girl gone bad’ aspect that appealed to her, psychologically. And what she got from Lorenzo was excitement, rather than unpredictability.

Apart from some extreme S&M stuff, there was nothing that was illegal either. She wondered how many people she knew wanted to try BDSM? More importantly, how many people were doing it?

After lunch, and more online searches, she decided to look at what people who were into BDSM bought. There were a surprising number of high quality online shops that sold everything from tubes to make your penis bigger, to any number of devices to hold you or restrain you in particular positions. Looking at the many BDSM accessories, she was also astounded at the amazing variety confronting her. Bondage clothing, devices, gadgets and endless objects to inflict both pleasure and pain. Some of the kit looked like it would require a call to an osteopath the second you got out it.

There was a particularly interesting diversity of costumes and outfits, and AVA even spotted the one that Lorenzo had got her to wear. Most of the stuff got good reviews and wasn’t particularly expensive either. A rubber Catwoman costume caught her eye. Hmm, she really fancied being Halle Berry in their bedroom. She simply had to buy something. She’d got out her credit card, her hand shaking with anticipation, as she made multiple purchases.

She had decided not to call Lorenzo that weekend, but it didn’t mean she couldn’t send him an email. She started typing, pausing to pick up the ‘master and slave unbound’ book again, the one Lorenzo had given her, as well as consulting the list she had made after her extensive internet searches.

She listed the things she liked about BDSM, and what she wanted to try. She paused, about to send it, a shiver of excitement running through her. She knew now, having read about why so many people liked BDSM, that it was the unpredictability of what Lorenzo had done to her that had made all the difference, and given her such an orgasmic high. After a moment, she decided what she had to do.  

Ava added a short single line and an X as a signoff to the email.

“But don’t tell me what you’re going to do to me. Surprise me.”

It was as she had finished the email and looked back at the online purchases she’d made, Ava realised she was tingling all over. Very carefully she sat down on a nearby comfy chair. She slipped her shorts off and then slid her black panties down to her ankles.

Ava started to read her favourite section in the book, the one on male dominance. She reached down, gently rubbing and massaging her clitoris. She realised she’d only ever really touched herself very tentatively, down below. Maybe that should change. She thought about what she’d read, about the mysterious Gspot, and decided she wasn’t going out of the door of her apartment until she found it.

She turned to the diagram in the book, slowly pushing two fingers inside herself, something she’d never done before. She was shocked to find her digits sliding in so easily so pulled them out quickly, turning and examining them, coated with her own silky goo. Experimentally, she put out her tongue, bringing her index finger closer. As if it were poison, she touched her tongue gently onto the tip of her finger. She tasted pleasant savoury notes, with an aroma that reminded her of happy childhood days at the seaside. The things she was learning.

Twenty minutes later, her fingers aching from the frenzied fumbling within her sopping wet insides, she screamed as she climaxed. Wow, why had she never done that before? She had circling thoughts tumbling through her head, all about what a future life of sub and dom with Lorenzo would be like.

But, on Monday at lectures, she’d decided it would be Lorenzo’s turn to understand a lot more about what she’d just read.

Role reversal

It was early morning, half an hour before she was due to leave for lectures, when Ava’s online order arrived in a brown package. She unwrapped it carefully, mesmerised by its contents. There was no doubt that black was a favourite colour for BDSM.

Laying everything out on her bed, the items all seemed to be straps and chrome fittings. There were also a few special clips with rubber pads and fine chains. She read some of the brief instructions that went with one or two of them, but most seemed relatively selfexplanatory. The only thing she had to get to grips with was a bit of practice doing up and undoing the buckles, until she was sure she could fasten them and remove them, within just a few seconds.

The most fascinating object sat in the palm of her hand, three chrome rings, two large and one smaller, welded together in a triangle. It looked like an odd napkin holder, with another ring as its base. The guidelines on its use were simple enough. No chance to read them through twice, it was time for lectures. She popped it in the pocket of her bag and left her room, whistling softly to herself.

At the college, she could hardly wait for Lorenzo to appear for their first lecture. She spotted his bag and scarf from afar, as he came down the hallway. She grabbed his arm, pulling him to one side, away from the throng of students entering the lecture theatre. He looked at her, slightly panicked at first, concerned at the lack of contact there had been over the weekend. She kissed him tenderly.

“Hey you. Miss me too? Sorry, had loads of reading and studying to catch up on over the weekend. Kept my mobile phone off.”

“Jesus, I was really worried. I called a few times but didn’t hear back from you. I thought we were over when you came in today.”

“For someone who comes across as mister confident, you worry too much. Don’t forget you gave me your book to read and, well you know, one thing kind of led on to another. I understand a lot more.”

“So, you read the book then? What did you think of it?”

“Yes, I read all of it, and I loved it. I went online too, a knowledge search, and ordered things for us to use. Today and tonight.”

His face broke out in a grin. He looked relieved and excited at the same time. He felt this was going to be a new era for them both.

“I’m sorry. I thought I’d gone too far in some of the things we did on Friday night. So, you enjoyed it then? You want to do more?”

“Yes, I do. I think I’m what the book calls a ‘versatile bottom’.”

He looked at the ual intensity coming across in her shining green eyes. He laughed out loud, but she frowned back at him.

“That’s inappropriate. And I’ll tell you why. Today I’m the master, or shall we say mistress. I need you to do something for me. In fact, you will do it. I need you to trust me as much as I trusted you three days ago.”

She pulled out a small brown paper bag, thrusting it quickly into his coat pocket. It was small and light. He wondered what it was.

“Toilet’s over there, off you go. The instructions are simple enough, but you need to secure that firmly. You’ll have to judge the best way to fit it, but bear in mind you’ll be keeping it on all day.”

He stared at her in a mixture of astonishment, alarm and lust. She decided it was an interesting look that she’d store away for later, for when the nights were dark and long, and she was alone.

“I’d head off if I were you, as you’ve only got ten minutes before the first lecture starts. Then come to the back and sit next to me.”

He hurried off. She moved casually to the rear of the lecture theatre where few students went, as it was more difficult to see the lecturer’s screen from the back. She sat down in one of the seats in the far corner, an area with dim lighting. There were no other students sitting within twenty feet, most of them wanting to appear keen, lined up in the front half a dozen rows of seats, waiting for the lecturer to appear, talking animatedly about what they’d done that weekend.

Five minutes later Lorenzo materialised from the door at the rear of the lecture theatre, having come up the back stairs from the hall corridor. He was walking slightly oddly. He eased himself very carefully into the seat next to her, his legs spread. There was a noticeable bulge in the front of his trousers. Ava turned and smiled at him mischievously, patting his swelling crotch gently. He looked around, to see if anyone was near or could hear him.

“Jees, this is tight. It’s right around my penis and balls. Feels like it’s cutting off the circulation down there.”

“I read what you have to do with it, it’s pretty fool proof. I’m sure it’s fine as long as it’s not too tight. It won’t cut off the blood flow.”

The finance lecturer came in, dumped her notes on the lectern and switched on the computer projector. The usual Monday morning buzz round the room went quiet. Ten minutes into the financial modelling review and Ava glanced across at Lorenzo to see him squirming in the seat next to her. He looked to be in pain.

“Hmm. Did you put the device on a little too tightly I wonder? Let’s see what’s going on inside these jeans of yours then.”

There was noone else on the back row or the one directly in front, so Ava slipped her hand into his lap. Stroking his thigh, she moved her fingers towards his groin. He started as her index finger touched one of his balls, swollen with the chrome ring fixed around his penis and beneath his balls. She cupped his genitals and penis through his jeans in her full hand, massaging both of his testicles gently with each of her fingers in succession, like limbering up exercises on a piano.

He turned to look at her, smiling weakly but wincing at the same time. Her touch slowly increased in pressure. She folded her fingers together around his crotch, like holding a tennis ball, his roasting hot gonads and penis inside held completely within her one hand. It gave her an immense sense of power, and she could feel herself getting hot and damp. She unzipped her jeans, pushing her free hand down inside her panties. He looked at what she was doing. Ava kept looking sideways at him, steadily. With one hand she played with his tightly constricted manhood and testicles, with the other she deftly fingered her hard clitoris.

She finished herself off within a few minutes, surprised at the strength of her orgasm. Her hand tightened briefly in his crotch as she came, a grimace appearing on his face as she clenched his balls.

Then she concentrated on him. She massaged his cock gently in her hand, sometimes softly, sometimes stroking it harder, trying out touching and poking different areas of his swollen anatomy, constricted by the chrome rings. After five minutes his face went a bright pink, and she felt his whole crotch area begin to spasm. His head went back and he uttered a deep groan as he came in his jeans. The lecturer paused.

“Sorry, but is someone struggling to keep awake there at the back? I suggest you get more sleep, young man.”

There was a polite laugh inside the lecture theatre, a few of the students turning round to look at them. Lorenzo’s face went beetroot red in embarrassment. Ava was still gripping him hard through his jeans, watching the changes in his reactions, loving the emotions and feeling of control over him that it gave her, beginning to understand the thrill of what it was like to be a dominant partner.

She freed her hand from her panties, suddenly remembering something else she’d read in the book. She leant over to flick a wet finger over his left nipple, squeezing it hard between her fingers. His eyes went wide. He tried to reach for her damp crotch, her panties still pushed open to one side, but she slapped his hand, gripping his balls tightly as a warning that he was in the role of her ‘sub’.

She decided to see if what she’d read last night could possibly be true. She’d heard that some men responded just as women did, but it seemed unlikely. So, with one hand tucked around his tightly restrained balls she continued to massage his nipple. She was amazed when it began to respond. It tightened up, like a small button, darkening slightly with engorged blood. It really worked!

She flipped the top button of his jeans open, playing with his nipple as she swiftly undid all the other buttons. She eased out his swollen manhood from the waistband of his boxer shorts. Everything looked pink and firm, as well as wet and very damp.

Each minor touch of the tip of her finger on his nipple now seemed to make him jump, so she leant over to tend to his other nipple. He was biting his lip hard in concentration, dark brown eyes closed, his breathing tight and hard. He had to lift his bum so she could pull his jeans down over his thighs. She saw the dark semen stain across the front of his boxers, carefully pulling them aside, glancing at the sticky cum as it was released, a thin trail making its way steadily down his thigh. Not as much of it as she expected though. Maybe that was the restriction from the steel ring.

As she pulled the elastic from the waistband of his briefs back harder, his penis suddenly sprang free, rock hard and erect, the glans purple and swollen. She could see he had pulled the device she’d given him over his penis, with the other rings sitting tightly around the base of his balls. Ok, so he had big testicles, maybe she should have got the slightly larger size. Hey, ho. His balls so tightly squashed at the base by the chrome ring was clearly why he was so sensitive down there. She suspected the way it fitted, it might be holding back some of his cum too. She would have to remember that for the future.

Watching his reaction to each slight movement of her fingers, she focused on his chest again, pinching and caressing each nipple in turn through his Tshirt. As his body stiffened in response, she pulled hard on the tight chrome device around his testicles. His balls were abruptly squeezed through the ring, both popping free.

The sudden release of pressure from the ring on the seminal vesicles leading from his rigid balls, combined with the rapid stroking of her finger across his left nipple, was just too much. His cock jerked, sending a blast of creamy white pentup cum high over the seat directly in front of him, spattering the back of the seats one row further away. Someone turned round and wiped something off his shoulder, imaging someone had just spat at him. She grinned.

She decided to avoid any further mess and put him out of his misery. Leaning deeply into his lap she took his rigid penis between her lips, licking and swallowing silently, continuing to pump into her soft waiting mouth more of the copious jism from his battered balls.

When she was sure he was fully done, she leant back in her seat, wiping a delicate finger across her red lipstick, smeared from her frantic ministrations on his exploding cock. Lorenzo looked completely spent, literally.

“Not bad, a bit salty, but yours is pretty tasty. Plenty of it too. That’s my protein supplement for the day, right there.”

Lorenzo couldn’t speak. He just sat there, his trousers round his knees. With only fifteen minutes to go to the end of the finance lecture, Ava rushed out the back exit to get some paper towels. She helped him clean himself up, as well as most of the obvious mess on several of the seats around them, before anyone noticed. The man with the semen stain across the shoulder of his jacket, three rows ahead of them, would just have to figure things out himself.

The rest of the day, Lorenzo staggered around, almost in a daze, zombielike. Several times he was asked questions by his lecturers, those who were eagle eyed and always on the lookout for victims that weren’t concentrating.
