Mizuhara Misono is an underwear model in Tokyo. She is on her way home to prepare to wish her only younger brother Mizuhara a happy birthday.
He is a naughty, mischievous child. Naughty with a dark personality, often playing depraved games, stimulating the desires of young boys in their teens.
Because of this, when the older sister gets a little drunk, in his body and accidentally revealing his big breasts to his eyes, he made up his mind that that night he had to be as good as his sister.
It's understandable because she was inherently a woman. According to the photo model, each round comes out like a round, each part of the body is beautiful and the younger brother has such a personality, so this thing that never happened is very likely to become a reality.
Indeed, that night he secretly sneaked into her room. Even though he was still awake, this naughty little brother didn't seem to be afraid at all, rushed in, squeezed her breasts and started to cum. The rush left her unable to react in time. What a spoiled child.
