Parents and children are not allowed to overlap their bodies. I know it in my head. And yet... Mio couldn't refuse her son, Koji, who tried to comfort her instead of her husband. Sexless for a long time. He longed for a hard cock that hadn't been touched sexually in a long time. Mio who made her body excited with her persistent caress and ferocious piston. She goes beyond the limit of orgasm in search of further pleasure before she is immersed in the afterglow.
