I planned to stay up all night talking with my best friend Ichiro, who doesn't have a girlfriend. But his girlfriend Mai appeared and it turned out they were actually living together. Hiding my shock while putting on a smile, I ended up staying at my best friend's house. When I woke up, his girlfriend was sleeping naked. Even knowing you shouldn't look, you can't help but stare at the stunning proportions, then touch, and before you know it, you're hard and inserting, waking up in surprise. But Mai finds the compatibility amazing and keeps climaxing. Then, until her best friend comes home, a day of non-stop sex begins.
