Unable to tolerate the large-buttocked female friend he moved to Tokyo with, he couldn't resist rubbing his penis against her in her daily life, arousing her until she was climaxing. He then held her tightly, and they had impromptu sex multiple times in a rear-entry position, with him ejaculating inside her repeatedly. (Onosaka Yuika LULU-441)

More than friends, less than lovers. I started living with a female friend with a huge butt, unlike a casual sex partner. One day, this female friend, who moved to Tokyo during my student days, started living at my place. Suddenly, this daily life with her huge butt began. Faced with her constantly swaying, incredibly prominent buttocks, I couldn't stay rational and immediately had sex with her! Because it felt so good, we crossed the line of friendship and ejaculated inside her without a condom! I became deeply obsessed with her perfectly fitting vagina, making love instinctively every day, feeling incredibly pleasurable! Having sex with a huge butt, it's definitely best from behind!
