After missing the last train at her club's welcome party for new students, she ends up having a house party with her senior Rika, Yuuma, and Takeshi. Himari, who still has that small-town innocence…is actually the target! Rika tries to boost Himari's spirits by getting her to drink more and more alcohol, while Yuuma and Takeshi grope Rika's breasts to create a lewd atmosphere! Rika and Yuuma, who have a physical relationship, take the lead and start having sex! Even Himari-chan, who has never cheated on her boyfriend, gets flustered by both her new life and alcohol, so she ends up having sex with Takeshi! Plus, they change partners and have a 4P orgy overwriting sex! Naturally, the two young people end up having internal ejaculation!! In the end, two groups split up and quietly confirm each other in different places for a refill NTR sex! Himari seemed innocent, but she seems to love sex. Her boyfriend back home, who is in a long-distance relationship, hasn't had any action in a while! From now on, Himari's heart flutters with excitement and mischievous desires for her cheating sex life...
