When I met my wife's sister for the first time, she was cute and had big breasts! I was captivated by her F-cup breasts, which were incomparable to my wife's... My dick was fully erect, Kokoro by the devilish temptation of my wife's sister! I couldn't resist the deep blowjob and the boob job that I couldn't experience with my wife, and we ended up having sex behind my wife's back... I was so excited by my secret relationship with my wife's sister that I had sex with her many times, near the family and next to my wife while she was sleeping. After all, men can't beat big breasts!
