IENF-279 A super cute schoolgirl takes on the challenge! Would you like to have your penis carefully sketched?

A candid awareness survey of young women. In the story, high school girls who are approached on the street and invited to a studio are asked how much they know about male anatomy while sketching it. As they carefully observe and draw it, they gradually become more aroused, eventually touching it directly and even trying to taste it. Before long, things escalate into intercourse and ejaculation.
