i'm a third-year university student. i have a girlfriend from school. after graduating from university, there's a vague mood of marriage. but honestly, i don't even feel like having sex with her. but still, summer vacation is boring. i'll just masturbate for now. is there any good masturbation material...? it started from the day i made eye contact with her... a dangerous secret meeting... a yakuza couple moved into the house across the hall. they have sex every day, showing it off by the window. ...ah, how lewd. me too...
