An uninvited female cousin comes to stay for summer vacation.
She's an adulating fan of her older male cousin who she calls "oniichan".
The little masochist does anything he says. If he's got to take care of the annoying, adoring loli, he' ll teach her how to be his sex pet.
Bloomers, bikinis, bondage, hole by hole by hole this M-loli is trained to satisfy.
