I moved to Tokyo to study for my entrance exams and moved into a cheap shared house! But all six of my roommates are women! And they're nudists!? Everyone is practically naked in the house! The only rule is, "Never refuse an invitation to have sex, no matter what." For me, a student repeating the entrance exam, this rule is like hell! These naked beauties, with no sense of chastity, immediately pounce on me one after the other, saying, "I'm getting horny!" Even though I'm a student repeating the entrance exam, I'm still a man! There's no way I could refuse in this situation! They're completely knocked out by them, having sex whenever they want, as much as they want! Before I knew it, I was knocking them out with my high-speed thrusts, forgetting about my studies! Even when my male friends come over, they're naked! The rules apply, and it's naked women and naked men. There's only one thing to do! Eventually, it develops into sex! My friends join in on the ultimate harem orgy, with lots of creampies! I'm sure I'll be a repeating student again next year, but I'm happy!
