MIDA-235 | My best friend's sister found out that I was a premature ejaculator, and she licked my whole body and made me cum inside her, making me cum 30 times in just 3 days...

I stayed at my best friend's house for three days. My best friend's sister (apparently she's called Unpai-san...), who is very close to me, teased me and I ended up ejaculating unexpectedly. But I still couldn't get it down... and she found out I have premature ejaculation! She immediately treated me like an ejaculation toy! Whenever she got the chance, she stroked and licked my dick and squeezed out my semen over and over again! [Sex near my best friend who fell asleep, sex in the bathroom, handjob and blowjob caught in the hallway, secret blowjob during breakfast] I was played with by my dick anytime, anywhere, and ejaculated 30 times! But I can't come anymore...!
