YST-112 — Hey You, My Body Has Become One That Can Only Get Aroused If Someone Does Something Cruel To Me. Karen Sakisaka

A cheating wife is summoned by her perverted sex friend and comes over. She comes from her house wearing only erotic underwear under her coat and with a vibrator inside her vagina. She is introduced to her sex friend's younger brother at the front door and her body starts squirming, but she senses the same perverted scent from him and her uterus starts throbbing. The younger brother, eager to inseminate his slave's vagina, observes the woman's entire body, and when he sees her licking his sweaty toes, he gets his cock erect and pushes it into her mouth, shaking his hips. He is inseminated by his brother, who doesn't stop shaking his hips even after a long time of sex.
