"So bind them. The cables will last another thirty minutes in any case."
The others slowly nodded at this suggestion. Consensus had been reached. The group of men approached the group of students. When the two companies stood facing one another, the leader of the invaders said: "Remove all your clothes." There was nervous shuffling among the students. They were packed into a tight corner, boys and girls squeezed tight together. They had been in the same art history class for six weeks now and only a couple of them had ever shared sexual secrets or seen each other naked. But the men didn't care. "Remove your clothes," the leader said again, and suddenly a slightly wild look crossed his face. It was the most unusual facial expression that had yet appeared on any of those identical faces. He almost looked mischievous. "Remove your clothes or we will cause you to feel intense sexual insanity." Nobody understood the threat and nobody moved. After a moment, the leader made a gesture and one of the other men approached a young man. He was holding a tiny vial of liquid. This he held up to the young man's nose and briefly uncorked. Quickly the bottle was sealed again, but the young man was already undergoing a transformation.
His eyes grew wide and his hips started to move. His hands shot out towards the nearest girl next to him, grabbing her breasts through her shirt. She yelped and tried to get him off her but couldn't, until another girl came to her assistance and pulled the groping fingers away. Before she could do anything else, the young man knocked this second woman down onto the floor and pushed his fingers down her pants. It was clear from the look on her eyes that he had immediately forced one and probably several fingers up her vagina. Then another girl came from behind to rescue the one who was being involuntarily finger-fucked. She took aim and landed a swift kick between the boy's legs, connected with his balls as they dangled in a particularly vulnerable position. The boy curled up in pain but at the same time a spasm shot through him as he appeared to orgasm in his pants. Finally he just lay on the floor with his hand down his pants, rubbing his aching penis and balls and crying softly to himself in a strange mixture of pleasure and pain.
"Would someone else like to experience this insanity, or will you remove your clothes?" The boys in the group imagined what we happen if they were forced to sniff the vial and went crazy in the same way. They knew it would end with a kick to the nuts in any case. The girls imagined themselves being overtaken by insane desire and jumping on the boys, demanding to be fucked. Slowly the students began to remove their clothes. Of course there were hesitations. Many of the boys did not want to pull down their boxers, because when they did everyone could see that their dicks were already achingly erect. The girls did not want to reveal their breasts and pussies to all these strange men, especially after seeing what had already happened. But there was no choice. Soon the small crowed of students stood pressed together in the corner completely naked, trying to keep their hands to themselves but at the same time sharing slight twinges of desire as naked skin pressed against naked skin.
Now the men entered the group and moved among them. This made the students extremely uncomfortable, but there was nothing they could do. They were already naked. One by one their wrists were locked behind their backs by those familiar lengths of featureless black cord. Their naked bodies were completely on display. As they were packed so closely, it became impossible to prevent swinging breasts and erect penises from knocking into one another. Hard dicks collided and rubbed back and forth. Nipples touched. The girls tried to keep their legs together to conceal the wetness seeping out through their pussy lips.
One of the men pulled a student forward by the nipples. She had beautiful breasts and a nice hairy cunt, but from out of her pussy lips protruded a clitoris that was several inches long, almost like a small penis. "An intersexed specimen" declared the stranger controlling her tits. "Statistics indicated that there should be at least one." He put his hand between her legs and began to rub her long dangling clit. She went crazy trying to pull away but to no avail. After a few moments another man came up and put his hands on either side of her, front and back, and plunged his fingers into her anus from one side and into her vagina on the other. The first man was still tugging on her big clit. She came with a moan and juice dripped down her legs.
Then the leader smiled that strange smile again and held up the little vial that had caused one of the boys to go crazy before. Very slowly and with all eyes watching, he opened the vial and spilled the entire contents onto the floor right in front of where the gang of students were standing. It made a small brownish pool on the linoleum. A few seconds later the students in the corner began to react.
They went crazy. With their hands tied behind their back they could not grab each other, so instead they just pushed. The boys jumped and rubbed agains the girls. Some of the girls lay down and spread their legs so that they could be fucked. Others swung their breasts around wildly, desperately trying to get a mouth to suck them. Other girls pushed people down onto the ground and straddled their faces, lowering their dripping cunts onto the mouths below. Boys paired off in a sixty-nine position to suck each other's penises. In the wildness of the orgy they also took one another's scrotum sacks into their mouths and sucked. Girls paired off in the same way and buried their lips and tongues in each other's cunts. After a few minutes people were cumming, but it didn't stop. Soon boys were throat-fucking people of both genders, and other students of both sex were moving backwards quickly in an effort to get their fingers inside of someone else's orifice. It hardly mattered what orifice anymore, as dicks and cunts were thrust and pushed against all body parts. Tongues and penises invaded soft wet openings. Hot vaginas rubbed their juice across faces and ball sacks. Everyone was rubbing and shooting cum into one another.
At a certain point a few of them leapt up and stared across the room to where three figures stood untouched by the effects of the strange chemical that had been spilled. The professor, the blond girl, and the first boy to have been grabbed had been too far away to be taken by what the intruders had called the hyperpheremones. They stared with incomprehension and fear as they were approached by a gang of students driven insane by lust. Luckily these three also did not have their hands tied. As a group of young men approached the professor, she was able to push them away from her with her hands. But soon there were five or six of them and she did not know what to do. Whenever she pushed their chests away they just came back again, their hard penises sticking out towards her, aiming for her mouth, her pussy, her ass. She felt very conscious of the way her heavy breasts were swinging around in front of her as she tried to defend herself, and of the way her thick brown public hair clearly marked the spot where each of these aggressive penises wanted to enter her older female body.
As a last resort she reached out to the two closest boys and grabbed them hard by the dangling testicles, looping her thumbs and forefingers around the top of their sacks and trapping their nuts away from their bodies. With their hands tied behind their backs there was nothing they could do either to get away or to attack her. As long as she kept her grip firm around their helpless nutsacks, they were entirely at her mercy and in her control. But the other guys were approaching her and now her two hands were full. Quickly she yanked down hard on the two scrotums she was holding. Since she had had such a good grip on their balls, the pull was wildly painful and the two boys collapsed to the ground. But now six other men surround the naked professor, and they too were staring at her three holes, wanting to get in. She reached out to grab two more nutsacks and succeeded, but as she pulled down on them the bodies of the raging young men collapsed against her. That was the last time her hands were able to get any purchase on their vulnerable male testicles. Now her hands flailed wildly as she was penetrated in every whole. A student lying underneath her drove his hard dick into her anus. She screamed and tried to close her legs but another young man stood was between them, and as he leaned over the suck her nipple with his teeth, she felt his penis force its way between her cunt lips and deep up inside her helpless vagina. Finally her mouth was penetrated too. She lay there wriggling about as the six men rubbed and fucked her until every hole in her body had been ejaculated into several times.
Things went equally poorly for the other two students who had not been effected by the lusty chemical. The girl was violated by fingers and tongues and cocks in each of her orifices, as was the boy. Both made an attempt to disable their opponents by striking them in the nuts or in the pussy or by pulling hard on their nipples. They had the advantage of free hands, but in the end they were simply outnumbered. Mostly they couldn't even tell what was happening to them. The boy's dick was in something warm but he had no idea if it was a mouth or an asshole or a cunt. The girl felt at least three tongues wrestling to probe and violate her pussy, but she had no idea whose they were. The three hapless witness were molested from all sides and in every possible way.
Then, all of a sudden and without warning, the little black cords that had been restraining the crazy students' arms broke open. An hour had passed and a timer had gone off somewhere. The students looked around wildly as their new freedom became apparent. At first their hands reached for one another, grabbing exposed pussies and tits and dicks wherever possible. One girl pulled a boy towards her by the scrotum and dragged his cock into her mouth. Another pushed a third girl onto the ground and straddled her, rubbing her pussy against the girl's stomach and pushing one of her dangling breasts into her mouth. But most of the students were staring at the ten identical men who had invaded the classroom in the first place.
The men began to edge towards the door. "Thank you for your time," one of them said nervously. Then they were all running towards the exit. Unfortunately for them, the exit was equally distant from the students as from the strangers. Three of the men got out before the door was pulled shut by a young woman with brown hair and pointy tits. She turned to face the intruders, now backed up by the rest of the class. All of them had a wild look in their eyes.
