Two Participants

With that, Kyra noted the machines on screen above Jonathan, as they were with her, humming gently in the warm room, reading every sensation. There must have been five men teasing her with brushes, yet her view of Jonathan was never interrupted.

Kyra cannot take her eyes off Jonathan's cock; two tongues slowly trace along from the base to the tip and back again, repeatedly yet never changing speed.

"Oh God!" Kyra hears Jonathan moan. She wants to echo his cry as the brushes keep lavishing her skin slowly, finally working just over her bra and panties, just grazing the outline of her sensitive points. They trail along her arms, down along her legs, across her stomach and chest, lacing her body with whatever oil the brushes are coated in, painting a soft, sleek trail sliding along her hot skin. Her cleavage rises and falls faster as they work her like artists practicing on their living canvas, her usually slightly small breasts heaved up so much more by the tight bra.

She hears Jasmine speaking to Jonathan, telling him to focus on Kyra. The young girl blushes even more, knowing he can see how vulnerable she is. Previously she may have been focused on her embarrassment, yet all she can now think of is how turned on she is. Watching the women on the screen begin to take turns engulfing his swollen length, moving their heads back and forth as they suck on him, makes her loins radiate with desire. Kyra throws her head back and moans out deeply from the pit of her stomach as brushes focus on teasing her; the oil makes the lingerie cling to her even more, making it almost see through. They circle around her pronounced nipples, gliding up and down her now plump mound, up and down against the slight elevation of the girl's aroused sex, the tightness and wetness of the panties not aiding in concealing it. She strains against the cuffs as if trying to control her level of arousal, sensing that something isn't right, having never been this turned on in her life.

"This oil seems to be taking effect nicely, which is just what you are here for, my dear," says Terrence in a pleased tone, before flicking the paintbrush tip up between the folds of her lingerie which clings to her pussy lips. Kyra lets out a yelp of pleasure, unable to control herself. This has an effect on Jonathan too, who lets out a cry of ecstasy before one of the women pulls her mouth from his cock fast.

"Please! I was so close," he yells out, before Jasmine takes over and masturbates him, her hand dripping with newly applied oil. Kyra watches as his muscles tense, the smooth glide of Jasmine's hand stroking his shaft rapidly, before letting go abruptly to leave his cock bobbing up and down in evidence of how close it was to release.

The slow strokes, the cruel administration of the oil, and the display of pure male desire all add to the whirlpool of craving.

"Please, more!" Kyra exhales as two paintbrushes slip up and down the outline of her labia, as if outlining a path to her clitoris - which is already aching with need for attention. She tries to close her eyes, trying to focus on anything else, but the moaning from Jonathan makes short work of her will. The pair of women with the straining young man continued to take turns lavishing his throbbing cock with attention, stroking and sucking it while massaging his balls, which are tight after being brought to the edge of orgasm repeatedly. The women appear to be wearing earpieces, being told just when to stop, keeping him constantly on the verge. The screen zooms in on his cock, dripping with a mixture of oil and precum, the effect of the oil mingling with the constant torture of stimulation making every vein bulge. If Kyra hadn't already been dripping wet, seeing this throbbing display of manhood on show and twitching constantly in need certainly would have made her so. Feeling the wet bristles trail along her cleavage and coat her soft flesh is an incessantly erotic tantalization, and coupled with the show on the screens, Kyra is finding it harder and harder to maintain any semblance of control.

"It is an aphrodisiac," Terrence says softly to her. The soft strokes do not relent for a second. "Made to affect males and females just the same, it is a fast acting, easily applied concoction of pure pleasure," he smiles up at her before brushing up and down the centre of those oily wet panties, making her shiver in the restraints. "It seems to be working on you both just perfectly. Do you want to come?"

"Y-Yes... yes, please!" she replies, not even considering the answer before it escapes her lips. Kyra watches Jonathan's hips rock constantly, bucking as if in sync with Kyra herself, whose pleasure is never allowed to rise to that sweet edge, instead trapped on a pinnacle of arousal which never rose nor fell. As one of the women tormenting Jonathan licked and sucked the sensitive head of his cock, the other jerked the shaft back and forth, both pulling away at the same time to leave him to fuck the very air itself, trying to relieve the sexual tension in any way.

"Please! Please, I need more. Anything!" Kyra gasps, yet the paintbrushes do not falter in their speed, continuously circling and stroking at a deliberate pace. Suddenly, Terrence addresses her.

"We are curious to see the effects it can have without the implications of getting you to the edge like your handsome friend. Often just edging itself can be seen as a form of release. Well, more than what you are receiving." He smirks before continuing, "I see it is already becoming a little too much for you. I think you are ready for the next stage."

"OH FUCK! Stop teasing, please, I can't take it..."

Two brush strokes sweep along her innermost thighs, where the line of her panties sinks against that sweet centre of femininity. The third, in Terrence's hand, whispers across her slit, the thin pink panties - soaked in aphrodisiac oil - doing little to dull the sensations of the bristles swiping across her clitoris. Every inch of her screams for so much more, envying the relief Jonathan must be feeling from at least being brought to the edge. Seeing his cock twitching and dripping was driving her crazy. She wanted to feel it inside her, feel it throbbing within. The fact that it was his eyes on her, seeing her arch her back, wriggle her hips and cry out in need, would have normally made her want to sink away. But she adored every moment he gazed at her. Her inhibitions were broken; all that mattered was the raw, animalistic cravings that clawed to the surface.

The two of them moan, gasp, writhe and beg in unison, it seemed like there was no end in sight, lost in a timeless void. As instantly as it had begun, however, the sensations abruptly stopped, leaving the pair panting uncontrollably. Terrence remained behind with Kyra as the rest of the group left.

"Tomorrow, you'll get what you want," he whispers to her, nibbling her earlobe. "You are going to be all his."

Before she can respond, he is already gone, leaving her to gaze at Jonathan. His cock pulses with his heartbeat, constantly throbbing with need: the need for Kyra's own juicy, full lips to wrap around them. She thrusts her hips out at the thought which had caused a rush throughout her body once more, thinking of how beautiful the sight and thought was, of how the harder he gets, the softer she gets. It was such a desperately erotic notion. The undetectable gas begins to fill the rooms as Kyra keeps her eyes fixed on that masculine frame, knowing that he is also watching her with animalistic desire. After several seconds of unknowingly inhaling the gas, the last image in Kyra's view before falling to sleep is the pulsating length of manhood she so desperately wants within her.

"They are quite the perfect pair, Jasmine," Terrence comments warmly to his colleague.

"Why else would I have chosen them?" Jasmine replies with a smile. "As soon as the girl put her name forward for the study, I had to see that sweet body of hers at its most intimate and primal. The same for Jonathan... speaking of whom, it appears the sedatives are wearing off, he is becoming erect again."

Looking through the one way mirror and watching the unconscious Kyra and Jonathan slowly stirring, the scientists observed undetected from adjacent seats.

"Okay, I'll turn on the cameras. I do hope the delay lotion proves as effective as the aphrodisiac," mutters Terrance distractedly. The awakening pair are naked and covered in oil, their shining bodies seeming to pulse with the pent up need for sexual release. "Clearly the effects of the aphrodisiac lotion have remained potent," he adds, flicking on the recorder once the pair inside the padded cell starts to stand.

"Shall we tell them about the delay lotion?" Terrance asks, not taking his eyes off Kyra, who stands in silence. The woman's hands automatically clasp around her breasts and between her legs, feeling the heat and losing the fight instantly against her need to come. Words escape her as she realizes the stimulation of the last few hours remains built up inside, burning throughout.

"No, I think they'll figure it out soon enough. Besides, I am curious as to how they are going to react, whether their base urges have consumed them." Jasmine's words are cool, contrasting the heated pierce of her gaze into the black padded room hazed with yellow light. She is intensely focused on Jonathan's cock, transfixed by how it instantly begins to twitch and pulse to its fullest erection without so much as being touched.

"If all is as planned, the male variant administered will be longer lasting and more efficacious," Jasmine adds just as the pair within the cell stops paying attention to their own bodies and notices one another. The scientists are on tenterhooks with anticipation as they watch Kyra and Jonathan, curious to witness just how they will react. The outcome makes them both smile with delight.

Kyra and Jonathan almost instantly spring towards each other, grasping one another with a deep, primal longing beyond mere physical attraction. The wet clap of their bodies meeting mingles with the slight, near inaudible gasps of them trying to communicate their need for physical attention, though with the recent sexual build up and continued pent up desires, they both know that their needs are beyond words. They paw at one another's bodies, pressing together, feeling the hot sexuality surging through each other, wanting to explore the other desperately. The sound of heavy breathing already fills the room as both of their bodies screams out for the fulfilment that has been denied for what feels so unbearably long.

Jasmine licks her lips at the sight of Jonathan's throbbing shaft sliding beneath Kyra's entrance, as if ready to thrust into her at any second. The scientist imagines the heat of her sex against that manhood, imagines just how intense the anticipation must be for Kyra, who Terrence had established had not experienced any penetration from a male in months.

"Perfect," whispers Terrence just as Jonathan presses his palms around Kyra's waist. There is a second of motionless apprehension, then he nearly throws her against the padded wall in a display of complete dominance before pushing his body to hers, lifting her up against the wall.

"Please, f-fuck me," Kyra exhales as Jonathan presses the tip of his penis against her entrance, already dripping with arousal down her thighs. Instantly, he buries himself inside her, making her gasp as he feels every swollen inch of his cock bore into her delicate folds. Jasmine and Terrence gaze wordlessly at the pair, watching as Kyra wraps her legs around the man drilling into her, listening to every squeal of joy and moan of pleasure.

"Oh God... oh God... oh God... please --!" Kyra whimpers in pleasure as she already feels the surges of orgasm course through her very core; with the way Jonathan's pace was changing, she knew he was also very close. Jonathan presses his body close to hers, feeling her breasts squeeze against his chest, feeling her astonishingly stiff nipples press against his skin, wanting to hold her tightly when he comes. Even at a distance, Terrence can tell that they are both close, the way their breathing is escalating, the way those hard, wet sounding slaps of skin meeting skin seem to be getting shorter and sharper, the way they are pulling each other closer to one another, as if trying to feel their hearts pounding against each other's chests.

"Fuck me harder... MAKE ME COME!" Kyra screams out, knowing that something is wrong, her heels resting on Jonathan's rear, feeling his buttocks tensing and realising that he must be experiencing the same thing.

Jonathan's breaths are ragged and deep. The tight pussy sucking in his cock, wrapped around him like wet silk, feels like heaven. Yet somehow he still hasn't felt the gush of orgasm spring from him, even though he was sure he was on the verge after only seconds. Quickly he pulls Kyra from the wall and to him, making her wrap her hands around the back of his neck as she hangs elevated, her legs still wrapped around him. With his hands clutching her waist, he starts to thrust into her like his life depends on it. Kyra's moans and squeals alone would be too much for him to take, yet somehow he still hasn't climaxed.

"I think they are starting to realize," Terrence whispers while the wet sounds of oily skin pounding against one another echoes through the speaker.

"It is so hot seeing these two suffer," adds Jasmine, watching the young man pummel Kyra's sex, every hard thrust so deep and fast it makes her breasts thump up and down while she holds on tightly.

"What... h-have... they... done?" Kyra gasps between thrusts, lost in horror at the sensation of not being able to climax even though it had felt like merely having his length slide into her would send her over the edge.

"I can't come... I can't.... come!" Jonathan yells out in desperation, though continuing to drill himself into Kyra's swollen red pussy. With a final thrust, he stops, breathing deeply but not allowing himself any rest before placing Kyra on the ground impatiently, keeping the tip of his cock resting at her entrance. They look into one another's eyes, seeing desperation shining back, both of their bodies glistening in a mixture of oil and sweat. With a sharp thrust, he drives himself into her; the wet slap of his balls against her ass cheeks with every thrust mingles with the frustrated moans.

"Please... please... Oh God oh God I'm still so close," Kyra whimpers.

Faster and faster he pounds into her as juices drip down Kyra's ass cheeks, both locked in a continuous cycle of need, constantly held on the edge but unable to peak. As more minutes pass, tears of agonised frustration trail down Kyra's cheeks. With one final thrust, Jonathan keeps himself buried inside her, feeling her sex convulsing continuously around him as if responding to the constant twitching and pulsing of his length inside.

"We've... got to keep... trying," he says breathlessly before sliding out, seeing the trail of her essence from her glistening pussy cling to the tip of his swollen cock, making him surge even more with overbearing lust.

Jasmine and Terrence give a knowing look and a smirk to one another before turning back to watch as Jonathan pulls Kyra to her feet. Without a word of notice, Jonathan quickly slips his fingers inside her, making her gasp in surprise before moaning in pleasure. Instinctively, she grips onto his length but is unable to do anything other than feel how much it throbs. She is seized in her own little world of ecstasy the moment Jonathan's fingers start to explore her. The masculine feel and speed of his hand slamming back and forth brings her to the brink again in seconds. Her legs buckle but he holds her upright, determined to finger-fuck her to orgasm.

After a while, after hearing Kyra spend minutes begging that it is too intense, that the sensations are driving her insane, he turns her around and takes her from behind.

It seems like hours since they had woken, yet still neither had climaxed. The procession of intercourse had now become a base, animalistic need. The two researchers could see how now they were truly fucking one another with a machine-like furiousness.

No matter what angle Kyra was penetrated from, her overly swollen clitoris was always being stimulated; whether from Jonathan's balls slapping against it, his pelvis pressing against it or his fingers manipulating it, her clitoris was constantly being tended to. The ache was desperately intense, yet anything to bring her closer to release was something to cling to. Finally, after surely a lifetime of unstoppable penetration, something seemed to be flooding through her system, a heat which seemed so familiar and so different at once. Somehow, she was certain that this would be her time to come.

Jonathan could see that something was different. While they had long passed the stages of speech, and having almost tuned out one another's constant moans, shouts and screams of agony bound frustration, he could see in her eyes a sense of realisation, as if she felt something different.

He carries on pumping his hips back and forth, with her lying on her back while he thrusts into her from on top. Again her legs clench around him hard, feeling her heels press against his lower back.

"I... I... I think... this...," she tries to speak, the new sensations of heat cutting through her consciousness. Suddenly, she lets out a scream of ecstasy so intense that even Jasmine and Terrence gasp and smile in response to. A sensation as if every orgasm in her life had been bundled in one and poured over her erupts from her body, through her sex, through her spine, through every inch of skin. Even as the scream subsides, her mouth hangs open as if there is not enough air in her lungs to vocalise the pleasure ripping through her. Jonathan feels her pussy tighten as if to push him out of her, but he stays inside, wanting to feel every convulsion. Her eyes closed, her mouth open still in tortured pleasure, he continues to pummel her pussy while she twitches, her body trembling from head to toe.

"O-okay... okay... pl -- oh, oh... plea -- ...please!" Kyra finally manages to breathlessly murmur. "It's... too much!"

Even while the shocks of her orgasm seem to surge through her with an unspeakable intensity, Kyra can do little to stop Jonathan's relentless need to fulfil himself. Her entire body is on fire with oversensitivity, she would just want to curl up in a ball and not be touched or spoken to, to recover from such a monstrous climax, yet still she is being fucked like a sex toy.

"Oh God... stop... please... I can't take anymore!" Kyra begs with no effect as Jonathan quickly turns her around and fucks her once again from behind. Taking her wrists, he holds her arms back, allowing him to thrust into her with brutal intensity while she hangs in his grasp.

"What a lovely sight," Jasmine gleefully says to Terrence, who is admiring the scene and delighting in the little screams escaping from Kyra's lips with every deep thrust.

Jonathan keeps pounding into her, feeling the soft cushion of her ass cheeks hit against his pelvis, growing more and more worn out with each second. Slowing down until finally he stops pushing into her, he speaks to the girl at last.

"Please, stroke me off, suck me! Do anything, just make me come," he pleads.

Without a word, Kyra turns around to face him as he lies back. She slides her body over him, giving him the temptation to grip her and fuck her once again, though he stays in place and controls himself. Kyra unexpectedly turns, positioning her knees on either side of his head, letting him look up to her brightly swollen red pussy still shining with her juices. In this 69 position, she finally presses her mouth to his length and closes her lips around it, placing her hand around the base of his shaft. She can feel every beat of his heart echoing through his cock, pulsating in her mouth. She sucks him, teasing the tip with her tongue while her hand works up and down. The sensations are unbearable for Jonathan, who wraps his arms around her waist to pull her delicacy towards him. The moment his lips press around her hypersensitive clitoris, Kyra pulls her mouth away and lets out a sweetly pained scream. Knowing he won't stop even though she can't take anymore, she works him faster, stroking up and down along his stiff shaft, masturbating him at a much faster motion than sex could ever provide. It takes a few minutes and she feels the base of his cock pulse on the edge a few more times, but soon the thrusting of his hips falters. That lets her know that a different sensation is sweeping through him: the feeling that this time might be different.
