Active-duty K University student "Natsumi" challenges herself in five different seminars aimed at mastering elite sexual techniques. As a research model, she studies the female body in a "Female Anatomy Analysis" course, discovering exactly which areas and how they must be stimulated to achieve pleasure, culminating in her first facial experience, where she learns the intense ecstasy of cum on her face. She also participates in a creampie seminar, where she reports on male pleasure points while personally experiencing the sensation of being filled inside. Additionally, she explores her first lesbian seminar, indulging in intimate girl-on-girl play, and an intense deepthroat seminar where her throat is penetrated so deeply that tears and drool mix in overwhelming sensation. The highlight is watching how Natsumi grows and evolves throughout her journey.
