Ayumi and M-kun, both strangers to the pleasures of the flesh, are thrust into an erotic awakening when Ayumi's husband leaves them alone. M-kun's innocent curiosity leads him to Ayumi's bedroom, where he finds her bathed in post-coital glow. Ayumi, feeling his young, hard cock against her thigh, can't resist the temptation. She takes him into her mouth, teaching him the ways of pleasure, before impaling herself on his virgin cock. They fuck hard, their bodies slapping together, their moans echoing through the empty house, their taboo love a secret they'll both cherish and regret.
