We got some college girls to participate in a show about their awareness of sex, posing as a survey about their sexual feelings! One girl mentioned that her friend gets off just from touching her nipples, making her envious. So, we decided to have an AV actor help develop her nipple sensitivity. As her nipples become more sensitive and she starts to feel pleasure, the actor relentlessly teases her! Even during sex, he keeps focusing on her nipples! This innocent girl transforms into a nymphomaniac!
