A female student, Ito, and her mother live together. Her mother's boyfriend moved in with them. This worthless man, who barely works, secretly leers at Ito. One night, the man lewdly gropes Ito's chest. 'I love sensitive nipples,' he says as he rolls her nipple between his fingers, causing her to let out a moan despite her disgust. Her nipple is rubbed, pinched, and licked... She reaches orgasm from the relentless nipple torture, but it doesn't stop there. Every night after that, she is lewdly played with, falling into a premature ejaculation constitution due to the incessant nipple harassment.
