HUNTC-600 "I'll jerk you off gently like this!" "Feels good? You're gonna cum?" "Stop it!" A serious study session turns into a dick study session! 2

A serious study session turns into a naughty penis study session! But it's my fault! I'm timid, but my standard deviation is high. Before a test, I always have a study session with my female classmates in my room, and I always teach them! However, the girls who come to my house have short skirts and are always defenseless, so you can see all the panty shots! When I was watching that, I couldn't concentrate on studying and got an erection...I hurriedly hid it, but they found out, and I thought they'd make me feel sick, but then a penis study session started with girls who were very interested in erect dicks... The mystery of a man's body, which girls don't know about, is thoroughly explored...
