Prestige's exclusive actress, Suzu Matsuoka, perfectly reproduces the super popular original manga "Because My Brother's Wife's Uterus Cries"! I, a college student, ended up living with my brother's couple due to certain circumstances. Mayu-san, my brother's wife, asked me to impregnate her instead of her husband, who has problems with his reproductive function, as a condition for me to live with them. I was excited about having sex with Mayu-san, whom I had secretly admired, but when we have sex, she seems very unhappy and cold, perhaps because she feels guilty towards my brother. Enraged by her attitude, I attack Mayu-san while my brother is sleeping! Mayu-san, who was showing signs of dislike, but still moaning while wetting her pussy, suppressing her voice! I vigorously piston Mayu-san, who is feeling more than I've ever seen before, and pour in overflowing semen! After that, as we continue our physical relationship and make her cum many times, we forget our original purpose of having a child and it turns into sex where we only seek pleasure! Suzu Matsuoka challenges a thick NTR story! Please enjoy the ultimate extramarital sex where they forget about insemination and fall into pleasure!
