After a breakup, a man calls Karin—his childhood friend and best friend’s girlfriend—to comfort him. He drinks himself senseless and, aroused by her devoted care, drunkenly forces her legs apart despite her protests. She initially resists but gradually stops fighting as her nipples stiffen, her panties soak, and stimulation of her swollen clitoris makes her cum. He forces his cock down her throat, then penetrates her dripping pussy. Though she begs him not to finish inside, she also cries out in pleasure, and he gives her a deep creampie. Karin scolds him afterward, but her expression suggests she did not entirely hate it, leaving him tempted to repeat the betrayal.
