Akari Niimura, a busty, innocent-looking wife, seeks advice on her husband's sexual demands. Wolf Tanaka, the expert, patiently explains with visual aids. However, his demonstrations prove too tempting for Akari, who can't resist tasting his cock. She eagerly sucks him off, her big tits pressing against his body. Tanaka, aroused, bends her over, slapping her ass before sliding his thick cock into her tight, unlubricated ass. Akari moans, enjoying the taboo sensation. He fucks her hard, making her orgasm, then pulls out, painting her ass with his cum.
