After my girlfriend dumped me, I decided to stay at my aunt's house in Tokyo for a while on a heartbroken trip. I met my aunt for the first time in years and she was incredibly beautiful, with a big ass and the erotic aura that's so typical of a gal... Unable to resist, I rubbed my dick against her big miniskirt ass, instantly ejaculating and cumming on her ass. She found out I was a premature ejaculator. My tomboyish aunt couldn't bear to see my prematurely ejaculating dick, so she trained it with a super slow blowjob. Her constant teasing and ejaculation control increased my erection stamina, and I ended up cumming inside her.
