I moved to Tokyo to take the entrance exam and moved into a cheap shared house! But all six of my roommates are women! And they're all nudists! Everyone is almost completely naked in the house! The only rule is that you must never refuse if you are invited to have sex at any time. For me, a student who has just finished taking the entrance exam, this rule is like hell! These naked beauties with no sense of chastity immediately attack me one after another, saying, "I'm getting aroused ♪"! Even though I'm a student who has just finished taking the entrance exam, I'm still a man! There's no way I can refuse in this situation! I'm completely KO'd by these girls who have sex with me whenever they want, as much as they want! Before I knew it, I was KO'ing them with my high-speed pistons, forgetting about my studies! Even when my male friends come to play, they're naked! The rule applies, and it's naked women and naked men. There's only one thing to do! In the end, it develops into sex! My friends join me in a harem orgy where we have sex and cum inside each other! I'm sure I'll be a student who has just finished taking the entrance exam again next year, but I'm happy!
