The beautiful bride, Mitsuki, takes devoted care of her elderly father-in-law. Despite his frail health, the vigorous father-in-law often gets an erection during care, causing difficulties. Mitsuki advises, "For your health, you should ejaculate..." but he stubbornly refuses. So, Mitsuki uses her seductive body to tempt him into ejaculating, even if he dislikes it. Gradually, Mitsuki transforms into a perverted, pleasure-seeking bride who enjoys her father-in-law's reactions while providing erotic assistance, softening his tough personality and winning him over.
