Ever since moving in with his mother-in-law Yukari, the son-in-law cannot stop wondering whether she might be far sexier than he ever imagined. Once the thought takes hold, he gives in to impulse and peeks while she changes.

Breathless at his first glimpse of Yukari's voluptuous body, he loses control of his desire that night and crosses a forbidden line.
