Biology Lessons

 — Vitya! Wake up!

Her voice brought me to my senses.

 — Why are you always sleeping in my classes?

 — I'm... I'm not getting enough sleep, Anna Yevgenyevna.

 — Well, are you awake now? Then let's continue...

And she began monotonously explaining something again. Anna Yevgenyevna, who tutored me in biology because I was falling behind in that subject at the institute, was unmarried and possessed a voluptuous chest and a rather sizable rear. She always dressed the same way—in an open dress, only the colors were different each time. She usually didn't wear a bra, and her nipples were faintly visible through the fabric. For several

months now, she had been the object of my sexual fantasies. Especially after that incident when Anna Yevgenyevna dropped a book and bent over to pick it up, turning her backside toward me, and my gaze was met with her long, beautiful legs. And sometimes during our sessions, I would get lost in thought about her like this.

 — There you go again! What's wrong with you?

 — Nothing, Anna Yevgenyevna.

 — Yeah, right, nothing. I'm explaining things to you, but what's the point? You're not learning anything. Today, you didn't do your homework again. Why even bother coming to the sessions if you don't want to put in any effort yourself? The sessions should be useful, but it seems like you're just bringing me money for nothing.

I shrugged vaguely, trying not to look at her chest.

 — I understand your parents will keep forcing you to come here anyway, that's just the way they are, what can you do. I have an idea. Wait here a minute. — With those words, she left.

For the first time in her lesson, I became interested. What kind of idea did she have.

 — Vitya, come here! — her voice called from the living room.

When I entered, she was sitting on the sofa, her legs gleaming invitingly.

 — Sit next to me. — I sat down.

 — I've noticed that in absolutely every session, you look at my chest, at my legs. Don't blush, don't be ashamed. It's natural, I understand.

She took my hand and placed it on her leg. I looked at her questioningly.

 — Why hide it, I've taken a liking to you too.

I slowly began to stroke her leg. She placed her hand on my cock, squeezing it through my jeans. Then Anna Yevgenyevna stood up slightly, turned around, swung her leg over mine, and sat on me. I placed my palms right on her firm buttocks, and we began to kiss. I moved one hand to her chest, began massaging it through her dress, and with the other hand, I started caressing her buttocks, slowly making my way under her skirt. Pushing the dress aside to expose her breast, I pulled away from her lips and buried my face in her chest, my tongue caressing her dark, aroused nipples. Meanwhile, my hand was already stroking her pubic area through her panties. Anna Yevgenyevna suddenly got off me, knelt on the floor, then, unbuttoning my fly, pulled out my cock. Smacking her lips, she began to suck it, lick it, while taking off my pants. She sucked until I came right in her mouth.

Then we switched places: after first taking off her dress, she sat on the sofa, and I knelt on the floor. I slowly pulled down her panties, and her pussy was revealed before me—hot, wet. I began to lick it, then buried my face in her crotch, trying to penetrate Anna Yevgenyevna with my tongue. Soon, she began to shudder from an orgasm. I moved up, caressed her breasts again, then we began kissing once more. My cock was already hard again. Placing it against the teacher's vagina, I smoothly inserted it, pulled it out, inserted it again, gradually speeding up. Then we changed positions: she lubricated her anus, and I began to fuck her right in the ass. Anna Yevgenyevna moaned louder and louder. Finally, I came without pulling my cock out of the teacher's ass. Semen began to drip down her legs, and she collected it with her fingers, then licked them. We sat on the sofa, continuing to caress each other with our hands.

 — Well, — she asked with a smile. — How do you like the biology lesson?

 — Wonderful, Anna Yevgenyevna.

 — We'll always study like this from now on, you don't mind, do you?

 — Of course not.

 — Well, look, your cock is hard again. — And Anna Yevgenyevna, kneeling down, began sucking it again...
