[Characters]
Mirina Kamiya
Nao's older sister who loves to tease him. Her favorite thing is to pester him, fuck him, and even dress up up as a girl. But she's completely unable to stand up to the might of his dick...

Nao Kamiya
A kind but unreliable young man. He's good at housework and often tutors his little sister. One day when she slips him some strange medicine, he goes a little crazy. Despite his cute looks, he just gets more and more perverted every day -- and his dick can't be satisfied.

Yua Kamiya
Nao's tsundere little sister who loves him a lot. She's the one that gave him the drug that made him go wild. She'll put up with all sorts of things as long as she gets to have sex with her brother.
