Takeru has become unbearably horny after his older brother with his wife and daughter moved in with him (he's feeling it mainly due to his sister-in-law's moans), plus his niece Hikari showing off her healthy body in casual clothing. It's gotten to the point where he wants to rub one out and find relief at once, but his own room is occupied and he has no private space for himself. He is forced to endure this every day, and when he finally reaches his limit, Hikari whispers some sweet words to him: "Should I help you rub one out?"
