PPPE-449 | Her older sister has big breasts and is okay with unprotected sex, and she's trying to seduce me. - Ayatsuki Nanao

My girlfriend insists on condoms and strictly forbids internal ejaculation. Her older sister, however, is the complete opposite—she hates condoms and welcomes internal ejaculation! To top it off, she’s an absolute stunner with a beautiful complexion and a gorgeous, well-endowed bust. There’s no way I could resist her advances! I’ve been sneaking around behind my girlfriend’s back—getting blowjobs, and even having her sister perform *paizuri* (breast-sex) right next to my girlfriend while she’s fresh out of the bath! Her sister has an insatiable sex drive, and we’ve managed to have unprotected sex countless times, all while keeping it hidden from my girlfriend. The mix of guilt and the thrill of the forbidden has turned both of us into sex-crazed maniacs! In the end, my girlfriend caught us—so I made sure to show her exactly what we were doing by ejaculating deep inside her sister, right before her very eyes!
