I'm an otaku and a virgin. My hobby is radio-controlled cars! I'm not interested in girls! ...I can't say that. My pathetic little sister has great looks! But she's a little too cheeky. She makes fun of me and keeps showing off her plump ass! Don't underestimate the pent-up sexual desire of a middle-aged virgin! I'm going to beat that cheeky spirit back in with my brother's dick!
