She's got 18 y.o. She's petite, slim. A quite tough squint. A smart brain, really brilliant. A student. And I'm a teacher of hers... I like her since when she was in her first class. Clever, critic, beautiful. Sexy. She's been abroad. She came back early, nobody knows why. She was hot, this morning, she took off her sweatshirt. A female friend of her kept her T-shirt so that it wouldn't rise too much during this process... so nice a gesture, so nice a girl. I liked her. A gratuitous gesture of attention. A whit T-shirt. I can guess why her mate payed that attention. It's clear, no bra and a couple of pieces of body jewellery. I talked with them, but sometimes my eyes fell on her chest. I was feeling an erection growing up. While I kept my lesson, I could think about her nipples in my mouth. I imagined her getting hornier at my tongue. I read that women like getting their nipples sucked and licked; my wife didn't like it too much, when she let me do that....
