Even a trained Head Girl still had limits after hours upon hours of endless fucking and stimulation. It was inevitable even by those who experienced such unrelenting assaults by alien guests. The silver haired woman coughed up some fluid between weak groans. Heat pulsed throughout her body, drowning her in wondrous pleasures. Drool foamed from her gaping lips. Her hypersensitive body came around the thrusting tendrils, her drugged body unable to resist the flood of stimulation the fluids brought forth.

"Uhnn... Uhhhnnn... Ohhnn..." Vera moaned as the tentacles eventually slowed. No more tendrils replaced them as cum drooled out of her ass and cunt. Her body glistened with sweat and alien fluids. Breasts rose and fell with shuddering breaths. Whatever the creature was doing now, there were no words of protest nor efforts to hinder the alien guest.

As her body moved - as if on instinct - to serve his carnal needs, he responded to her by using the narrower tentacles that circled her to finally close in on her, and massage her. Seeking out particular pressure points that would provide relief against the rough session she had endured for what must've felt like hours and hours, he returned the favor by giving her the sort of reward he usually had kept ready for those humans who ultimately cooperated with him. Looking over what she had been doing when he had captured her, he decide to put her through a particular treatment designed to eliminate fatigue in the victims. The duo of tentacles that had repeatedly ejaculated inside her finally drew out, causing her battered ass and pussy to leak those warm fluids all over his central section.

As the powerful suckers on her nipples finally yielded, sparing her teats from any further torment - they were replaced by the tongue-like thing licking her throbbing nubs, applying more of that warm gel that seemed to chew up the pain and swallow it as it was applied onto her quivering, puffed-out areolae. Small, almost hairlike tendrils moved up against her beaten nethers, slowly prodding and brushing up against her still dripping vagina and anal hole before settling in around them in an odd figure-8 pattern. Whatever those things started doing to her, it felt pleasant - not the wild bliss of being double-penetrated and fucked hard, but this was a subtler - yet filling sensation. Her cervix closed up, refusing to let any more of that warm liquid drip out of her. The subtle heat in her womb began to diffuse out into her whole being, her stomach providing a similar sensation with his hot seed.

Satisfied that his initial massage went well, he began to dress her back up. The fact that she was nearly slack from the hard three-way fucking he had given her helped. Taking care to avoid staining her clothes with his jizz, he quietly admired how well her body had responded to the medicated gels he had sprayed onto her well-worked cunt and ass. Engineered precisely to service and repair human cellular structures, the stuff began to heal her beaten body, and by the time he peeled off the spent drug gel from her body, her pussy was a spectacular thing - a single tentacle brushing down her lips were rewarded with a powerful sucking kiss. He almost took her again right there and then, but held back.

Vera was eventually spared further sensual insanity. Tongues dragged across her throbbing and tingling flesh. Tendrils gradually withdrew from the silver haired woman's body. There was not much damage to begin with and what damage there was would have healed easily enough through NICE's technology. This Head Girl's lovely form was modified to last and she was no stranger to being stuffed full of alien appendages and cocks.

There was no sign of struggle from the woman. Eyes were shut as the Head Girl's body was finally allowed to slow down and cool off from the near endless fucking. Her gym attire was pulled back onto her glistening body. Weak groans left slightly parted lips. Her mind welcomed the darkness that gradually smothered what consciousness she had left. There was little danger of being found in such a defiled state by other students. Either Vera would recover on her own and seek a much needed shower before continuing with what was left of her day. Or nearby staff would retrieve her unconscious form to be spirited away from anyone spotting her in such a state.

Vera weakly twitched as the last of the aftershocks rippled throughout her body. Breasts rose and fill with slow deep breaths. The Asian woman would have much to work through when she wakes up. For now, it seemed the creature was not interested in ravaging her unconscious body further.

As her body relaxed, the alien cocktail of drugs that had been shot into her began their work. First off, was to slowly restore the elasticity of her slightly-widened anal and vaginal holes that still dripped with rivulets of cum that worked their way out of her. Thanks to all the samples he had collected beforehand, the drugs used had been tailor-made to leave absolutely no trace and break down harmlessly in their bodies. The more samples he had, the better he could experiment on these fantastic humans.

As her breathing eased off, the next set of drugs began to work, providing her muscles with much-needed rest and recuperation as the buildup of exhaustion was met at the chemical level and taken apart while powerful muscular lengths massaged her back, legs and arms, leaving them limber and tension-free. The cortex computer remained silent, a silent observer who would catalog his findings for later. As the medicated gel that held her well-worked lips together slowly crumbled apart as its payload was delivered into her flesh, he admired just how tight and perfect she had become, running a single caressing tentacle over the pink line of her vaginal crease, and admiring just how smoothly well her toned muscles moved in response. While he would have loved to take her for a ride once again and experience that brutal tightness once more, she was in no condition to endure such a run again - besides, it was more interesting to see how they responded when they were wide awake and aware of what was happening.

Finally, the cleanup. Such a splendid, mature specimen getting injured, or worse - dying from slipping on the liquids that had spattered below her would have been an unacceptable loss and he made sure to leave her just so that she wouldn't injure herself when she finally woke up. With the care a forensic scientist collecting any residue left on the floor, he left her in the standard breathing position to make sure she wouldn't have problems breathing. With one last, hopeful look at her, the creature withdrew at last, leaving the silver-haired beauty sleeping off her extreme workout.

He would have to try her again once she had recovered. The muscular ridges lining his tentacles shifted in anticipation of that day when he would take her again.

More. Wilder. Deeper.
