Kokoro is a young lady who has started living on her own, but her parents, worried about her, sent a servant to look after her. The selfish Kokoro, looking for ways to kill time, makes the servant wear nothing but underwear and blindfolds him, forcing him to walk around the house. Bored and friendless, Kokoro begins to tease the blindfolded servant's nipples. As the servant trembles and moans, his cock becomes hard before he knows it.
