大学生活が始まりせっかくの一人暮らしを満喫しようと思っていたら、学校から家が近いから友人たちのたまり場になってしまった！しかも彼女を連れてきてボクの家でイチャイチャしたりと、一人の時間が潰れまくり…。しかもその彼女が一人で泊まりにやってきて、無自覚な誘惑をしてくる。ボクは我慢できず……一人オナニーをこっそりと！しかしそれが見つかり、流されるままエッチに！そのまま学校をサボって朝までしてしまう！

University life has begun, and I was looking forward to enjoying living alone, but because my house is close to school, it's become a hangout for my friends! On top of that, they bring their girlfriends over and make out at my place, so my alone time is completely wasted… And then that girlfriend comes to stay over by herself and unconsciously tempts me. I can't resist… so I secretly masturbate! But I get caught, and things escalate into sex! We end up skipping school and staying up until morning!
