To feel the completeness of the plot, I recommend reading the “History of Nasty Prologue”. With love, Mr. Kaplan.

Nastya stood in the middle of the room and did not move. She was frightened by the actions of Andrei Samoilovich, at that moment he was standing at his desk and was engaged in his own affairs. After a while he looked at the clock that was hanging above the door, and said:

- Time to sleep.

Then he went to the toilet, came back and began to undress. She turned away when the biologist undressed. Nastya did not know what to do and say. He sat on the bed and told her:

- What are you standing there for me to wait long for you?

- H ... But where can I sleep, there is only one bed.

The bed was not very big, it could fit two thin people, but Andrei Samoilovich was full, so he occupied most of it himself.

- Are you completely stupid or what? You will sleep with me. And now take off your clothes - a biologist declared in command.

Nastya was shrouded in fear, she continued to stand, not knowing how to react to it.

- Maybe I should tell the director that you refuse, is here. And then you will be kicked out of this academy, little rubbish.

These words influenced her, and Nastya took the clothes for sleeping from the closet and went to the toilet to change her clothes.

- Where are you going? Said the biologist.

- Change clothes.

- Change your clothes here.

- But I can not, Andrei Samoilovich.

“Should I repeat what I said again?” The biologist asked irritably.

Nastya turned her eyes away from him and began to undress. She took off her shoes with socks, then took off her white blouse. The biologist has a view on the breasts of a young girl. They looked resilient, not very big, but not quite small. Because of the coolness in the room, the girl’s pink nipples were sticking out. She took off her skirt, after which a girl’s white tight panties appeared, in which, if you looked closely, you could see the outlines of the genital lips. She put her things in the closet and was ready to put on her clothes for sleeping, when suddenly. The biologist, abruptly jumping from the bed, took her hand and fell down with her on the bed. He laid her on himself, facing him, bent her legs to his knees. He covered the top with a blanket, and pulled the rope over the bed to turn off the lights in the room. Under the blanket, Nastya felt on herself the hands of a biologist, who continually stroked her back, dropping to her bottom and feet. Nastya turned her head toward the wall and began to cry softly. She felt a thick hairy body under her, she was disgusting, but she could not do anything. Also between her legs, in the pubic area, something firmly reminiscent of a stick appeared, there were some assumptions in her head, but she simply tried not to think about it. Because of a rather long and difficult day, Nastya still managed to fall asleep.

Nastya suddenly woke up from a strange feeling in the body. She began to look around, it was dark in the room, it was still night outside, but she noticed that there was no biologist in the bed. Incomprehensible sensations continued, and she realized that she was feeling something wet and moving in her crotch. She threw the blanket to the floor and looked at it. To her surprise, she saw between her legs a biologist, who stuck her mouth to her crotch.

- What are you doing?! - shouted Nastya.

The biologist did not react to her and continued to lick the girl's pussy. Nastya thought what to do to scream and call for help, or try to escape. But she knew that if someone had seen her, in this form she would have died of shame and disgrace. Then she decided to just lie down and try not to pay attention to it, although she was rather scared, since she did not know why Andrei Samoilovich was doing this. She didn’t know much about sex, she didn’t have guys, she was a homebody and didn’t often go out.The biologist licked the pussy of the girl, then spent his tongue on the bulging sexual lips, then the smooth pubis, then to the hole and the clitoris. After some time, Nastya felt a pleasant warmth in the lower abdomen, she was very pleased by the actions of the biologist, although she did not want to admit it. She simply lay and tried to distract her thoughts, but her body felt pleasure. After a few minutes, the heat between the legs began to rapidly change to heat, and this heat began to envelop the whole body. Nastya did not know what these feelings were. She wanted to be afraid, but pleasure quickly replaced fear. The biologist, sensing that Nastya was nearing orgasm, began to pick up the pace. After a moment, the girl's legs began to tremble and twitch, her body bent in a bend, her hands clutched at the bed, and her head lay back. She closed her eyes, euphoria and trembling all over her body. She screamed shortly. The body began to twitch convulsively, she floundered like a fish, she was very good. Nastya has disconnected from such unexpected emotions.

Morning came, Nastya opened her eyes, stretched and sat down. It was clear outside, the rays of the sun covered part of the room, which was why the room was bright. Nastya looked around, there was no one else in the room.

- Maybe it was a dream? - asked Nastya.

When she pushed the blanket back, she saw traces on the sheet between her legs, as if something had spilled and dried over night. The lock clicked in the door and Andrei Samoilovich entered the room.

- I see, slept well after last night.

Nastya, looking at him, said nothing.

“Ha, of course, you slept well, see how you made the bed.” By the way, you'll clean it yourself. I wanted to fuck you, but you turned off. Even strange, you ended up powerfully, I suppose, for a long time there was no guy?

- I didn't have a boyfriend.

- Did you have sex? - Andrei Samoilovich asked with interest.

- No - confused answered Nastya.

- I do not trust you! Look at yourself, like you just need to fuck. Daika, I'll check you out. Spread wide legs.

The biologist knelt by the bed next to the girl and spread her legs wide. Before him opened a gorgeous view of the crotch of the girl. Everything was perfect, a neat, smooth pussy of a girl, slightly plump sexual lips. The biologist spread the tender bud of the girl with two fingers, and he saw a small hole, spreading her pussy even wider, inside the hole, he saw a hymen.

“So you are really a virgin,” the biologist said happily.

- Well, nothing we will fix it soon.

From these words Nastya grabbed a fright. Andrei Samoilovich lowered his hands, kissed her pussy and sat down next to her.

- Do you even touch yourself for fun?

- Not.

- I see, then I will teach you sex. Let's call this extra-curricular activities, the biologist said maliciously.

- I ask you, Andrei Samoilovich is not necessary, please, I do not want - Nastya answered sadly.

“It will do you good, you will thank me again.” Today is Saturday, I have some plans for your evening. But now, you will have to repay me. Yesterday means you finished, and I do not, it will not work.

With these words, he took off his pants and pulled out his penis. Nastya was shocked by what she saw. A member of the biologist was in a supine position.

- Your first lesson. You must wake him up. Take it in your hands and start stroking.

He took her hands and pulled her to his cock. Nastya took the dick in her hands and began to stroke it, as if stroking a cat. After a short time, the penis began to rise. Nastya was scared, but at the same time she was interested in watching it. He was 15 centimeters slightly thick in diameter. Nastya went through anatomy and knew only basic information, but to see in reality this is different.

“Put your arm around him and start moving your hand up and down.”

Nastya did as the biologist told her.

- Yes, good bitch. Look into my eyes when I masturbate.

He turned her face towards him and began to look at her. Nastya blushed and began to look away. Suddenly a biologist hit her on the cheek and said:

- Look me in the eyes of a bitch.

Nastya raised her eyes to him and began to look. She felt ...
