A man with a plain face walked into the lecture room. The students turned and looked. Even the professor looked. There was something about this man that was too innocent, too curious. As if he had never seen a classroom. A moment later an identical person man the room, followed by a third and a fourth. Very quickly ten identical men stood in the doorway, each bearing that same plain face. The last one in closed the door. The students were too shocked to move, as was their teacher.
"Dzien dobry," said the first man.
"English," corrected the second.
"Excuse me. Good day," the first began again. "We apologize for the interruption. However, we have selected your classroom as a temporary laboratorium. During the following hour we will use your bodies to increase our comprehension of the sexual dimorphism in humans. You will not be able to prevent this. After one hour, we will leave and you may continue with your business."
Several of the students had gotten up and moved away from the door. The professor was nervously shuffling her papers and looking around to see if there was a phone. Because it was an auditorium there were no windows, and because it was late on a Friday the building was empty. The invading men did not appear armed, but they did appear confident.
"Please one standard male and one standard female step forward," continued the leader. When nobody moved, he approached the closest boy and asked him, "Are you a standard male?"
The boy stared back at the stranger crazily. "What do you mean?"
Quickly the stranger approached the young man and took him by the wrists. Although he did not appear especially large or muscular, it was apparently no problem for him to pull the boy's hands behind his back. From somewhere he withdrew a small black cord and fastened it in a split second to the boy's wrists. Then he stuck his hand down the boy's pants.
The rest of the students went wild. The boy who's genitals were being grabbed yelled out for help, but the rest of the students went in the opposite direction, away from the strangers. The boy was held immobile for a long second as the stranger's hand probed him between his legs. The rest of the students back into a corner as the other men approached them. Although they appeared plain and non-threatening, nobody wanted to challenge them after seeing how easily the first boy had been subdued. But the strangers approached the crowd, and one said, "Please step forward one standard female."
The professor had ended up in the front of the group and she was approached first. One of the strangers was looking at her chest. She instinctively moved her arms to cover up a bit, but he grabbed them and easily locked them behind her back, the same kind of short black cord appearing from nowhere and locking as if by magic. Then he put his hand down her pants.
"Stop!" she cried out, speaking instinctively and almost against her will. "Not me! I'm too old!" The other students were bunched up in one corner of the lecture room. The men had spread out through the space and several of them were clearing an area on the floor.
The man whose hands were down the professor's pants stopped and looked at her. After a moment, he said "There's a difference?"
"Yes!" she cried wildly. "For anything sexual you want a younger woman!"
"Who is a younger woman?" he followed up.
The professor briefly glanced over at a young blond girl across the room. The blond girl stared back at her with hatred. The man gave tilted his head and two other strangers went over to the blond girl. This time some of the other students tried to intervene. There was nowhere else to run, and the atmosphere was increasingly terrifying. Two large guys placed themselves between the two strangers and the blond girl. In a second they were lying on the ground, hog-tied with those same little black cords. The two men took the blond girl by the arms and led her to the center of the room, where the professor and the captured young man were waiting.
"This is an older female," said one of the strangers, presenting the professor to the group. "Let us compare her breasts to those of the younger one." Without another word the men ripped the shirts off both women. The professor's thick white bra held up two very large breasts, just beginning to sag heavily with age. The young woman woman wore a sports bra. In a flash both bras had been torn off and the two women stood with their tits completely exposed. Men approached them and began to feel up their boobs with their hands. They worked dispassionately but thoroughly. It did not appear that they were sexually aroused, but the women were made to feel extremely uncomfortable as their breasts were squeezed and pushed and maneuvered in various ways. One of the strangers took hold of the prof's tits by their large brown nipples and pulled them upwards so that they pointed to the sky. She gasped with discomfort and humiliation. Then he dropped them suddenly and her breasts fell down, bobbing slightly as they dangled. Next he pulled sharply her by the nipples into a leaning position, so that her breasts dangled heavily and swayed from side to side. The same things were done with the blond girl's tits. She looked even more uncomfortable as her smaller, firmer breasts were massaged and fondled in what still appeared to be a scientific way. Finally the men ripped off the shirt of the young man and began to play roughly with his nipples.
"We're not getting a response from the male," said one of the invaders. "Do you think that male nipples are less responsive?"
"I don't know," replied another. "Try stimulating his genitals simultaneously." The young man pulled away from his captors and tried to run away, but they had hold of his jeans and pulled them quickly down so that he tripped on them and fell. Soon they had stripped him entirely and stood him upright again. Three men surrounded him and put their hands all over him. One stood behind him and continued to play very roughly with his nipples. The other two started grabbing and minipulating his scrotum and penis. It was obvious that they had had no practice in sexual stimulation, for the handling was very rough. After a few moments they bent the boy over and one of them stuck a finger up his ass. The boy screamed. "We are not succeeding in arousing them," one of the men announced.
"Try intercourse," suggested another. Immediately they approached the young blond girl and pulled down her pants. She pulled away from them struggling but they lifted her up and slid her white panties off her hips and to the ground. Then they lay her across a table and spread her legs. "Begin intercourse," one of the men said to the boy.
