Bored as I was during the lecture, I tried to hold eye contact with whoever turned around for whatever their reasons. I sat about middle from the back row so I had good view of almost everyone. Whenever I saw a girl turn back, whether talking to someone else, stretching, or getting stuff out of their bag, I tried to hold the eye contact however seconds she allowed before turning back to focus in class.

Once, I made an eye contact with mildly attractive girl. I tried imagining of fucking her (I don't know where I saw/read to do that or maybe I was just horny). I think it was good 5 seconds before she broke the eye contact. I felt blood rushing to my head (not the other head) and my heart began to race.

Not the best setting that I could have done that. But was I being creepy doing it?
