Hiroto, engrossed in his visual novel, hears his wife's voice from the other room, prompting him to pause his game. Intrigued, he approaches and finds her masturbating, her fingers buried in her wet pussy. She gasps, caught off guard, but invites him to join. They engage in a passionate 69, their bodies entwined as they pleasure each other. Hiroto's thick cock slides into her mouth, while he laps at her clit, making her squirm. As they switch positions, Hiroto's cock finds its way into her tight pussy, filling her completely. The room echoes with their moans, culminating in a messy cumshot, marking their taboo tryst.
