Math class droned on and on. I could hardly pay attention to stuff I couldn't understand, so at a certain point, I mostly tuned it out, My parents would probably be unhappy if they found out, but, honestly, could they say that they didn't sit blankly through some of their high school classes?

As my mind wandered, it went, as it so often does, to thoughts of girls. You can't really blame me, I'm a teenage ${gender}. Something about hormones or something? I had difficulty focusing during that class, too.

For all the thoughts about various girls at school, it wasn't like I really knew all that much outside of what I could see from their clothing or what people would gossip about around me. I was just the quiet kid who daydreamed in class, I wasn't popular enough (or at all) to—

"Psst!"

A whisper from the seat next to me woke me from my musing. Hopefully it wasn't because the teacher called on me or something, that'd be embarrassing. I also hope I didn't jerk awake and draw attention. Carefully looking around, it seems that isn't the case. That's a relief. I turned my head toward whoever wanted my attention. It was the girl that usually sat there, though I don't know why she did. Probably because the teacher rarely paid attention to what happened in the back of the class.

If I'm honest, she was definitely one of the girls I thought about when daydreaming. Blonde and thin, with her uniform blouse seeming maybe a size too small, giving occasional tantalizing glimpses of what might be her bra underneath. I thought I saw a flash of purple when my eyes darted to the gap between buttons, but they darted away just as quick — I didn't want to be thought of as staring.

Seeing the glance, she smirked and, to my surprise, hooked a finger under the edge of her (probably shorter than regulation length) skirt. Slowly, the hem on the side went up, up, and— Are those bikini bottoms? P-panties? Do those even have strings on the side to tie like that?
