Quick story
Back in high school, I already had a taste for this fetish, but I wasn't open about it. Also, I didn't have a girl at the time, so world class loser reporting in.
So one day during afterschool detention, I'm sitting in a class room, mean ass teacher in the front, two guys to my left and right, and this tan girl in the front of me. She's wearing one of those skirts that just hover above the knees, long black hair, and freckles. I'm a freckle guy as well.
So we are sitting there, and I notice she puts her head down. I'm thinking she's sleeping. Some time goes by and I get hit by this smell. Like day old milk, and I'm not the only one. The guys to my side are looking at me, I'm looking at them, doing the silent was it you thing. One guy starts coughing hard, and asks to leave to get some water. Has to go in doubles so he couldn't just skip detention. So it's me and the girl plus the teacher. I go back to what I'm doing and I happen to notice that she's shuffling in her chair a little. Got to pee probably, but no. She pokes out her butt just slightly and tenses up before she relaxes in her chair. Wasn't long before the smell hit and it was clear where it came from. So I clear my throat, and you know sniff like I'm clearing my nose. And she looks back. I just smiled my geeky ass smile and patted my nose so she knew I knew. She turned around quick and sat there. So some time goes by and the guys haven't come back. Teacher leaves to find them, guessing they went for a smoke. So we sit there, and she turns and says sorry and don't tell. I tell her it's fine and I won't tell. I'll even claim them if she'd keep it up. She didn't but I wish she would have.
