MIDA-189 _Sister, I want to fuck you

Her parents are often away from home, so only Kanan and his younger brother Yuzuru live together. Because his family situation was not good, Yuzuru gradually withdrew into himself, becoming a hikikomori since middle school. Kanan always pampers his younger brother to the fullest, always meeting all of his brother's requests, including... satisfying his sexual needs. Every time Yuzuru feels horny, he will go to Kanan for help, but Kanan won't allow him to put his dick in her pussy. Ten years have passed, and the two's wrong relationship still continues. But now Yuzuru couldn't take it anymore, he sneaked into his sister's room and fucked her while she was still sleeping. Actually, Kanan was not sleeping at all. She knew what was going on but still pretended to be asleep, because Kanan herself was also horny, she had wanted to do this for a long time...
