HUNTB-429 Woke up in the middle of the night to find his brother masturbating and the end

Moved to Tokyo and lived alone in an apartment just a minute's walk from the university! I am shy and harmless, so a girl in class told me, 'I'll come early tomorrow, so stay overnight!' and came! Of course, I didn't have the courage to do that. That's why I secretly watched AV at midnight and chewed. However, a girl who should have been asleep looked at me like that!
