Hina, a 19-year-old slender girl with big breasts, doesn't know about vaginal orgasms, such as the G-spot or porcio. This project is about developing her and having her orgasm over and over again. Despite her young age, her sensitivity is excellent, and in the early stages of development, her love juices are flowing and she even squirts. If you insert your dick as is, she will squirt and be dazed. If you poke her uterus with a vibrator, she will scream, "It's hitting me, no!" In the latter half of development, she will drool and pass out. During the final sex, her vagina tightens and you can end up with a sudden cumshot.
