A super serious literature girl is fascinated by men who get hard-ons over something as trivial as panties! The literature girl's panty shot makes him fully erect! Although she has extensive knowledge about sex, her experience is limited. To satisfy her curiosity alone, she ends up seeking a real erection for the moment. It's not so much about sexual desire but rather a desire to satisfy her curiosity! She touches the erect penis, but by the time she realizes it, her vagina is soaked and the literature girl is dominated by her sexual desires. This is human sexuality that you can't learn from novels.
