A serious study session becomes a mischievous study session. But I'm terrible. Before the test, I always have a study session with the girls in my class in my room and always teach them. However, because the skirt is short and always covers it, it looks like a panchira. Seeing this, I couldn't concentrate on my studies and had an erection. I quickly hid it, but thinking about it would make me feel uncomfortable, when a lesson for girls curious about erections began.
