I moved to Tokyo for the exam and moved into a cheap share house! But the six roommates are all women! And they're nudists?! Everyone is almost naked in the house! The only rule is that you can't refuse sex if anyone invites you at any time. It's a hellish rule for a student! The naked beauties with zero chastity views immediately say "I feel like being horny ♪" and attack me one after another! Even though I'm a student, I can't refuse this situation! They completely KO me with sex whenever I want! Eventually, I also forget about studying and KO them with fast piston movements! Even if my boyfriend comes to play, the rule applies, and it's naked men and women. There's only one thing to do! In the end, it develops into sex! My friends also join in the most extreme harem orgy and creampie each other endlessly!!! I'll definitely fail next year, but I'm happy!
