SKMJ-066 The gentle older sister who loves her younger brother forbids incest.

She saw her younger brother as her older sister. "I know it's absolutely impossible, but I can't lie to my feelings..." I suggested taking a bath with my brother, letting my feelings flow freely, and we were both excited. It got higher and higher... the two of them kissing and hugging each other, unable to stop, forbidden from ejaculating through the vagina, and without telling their parents.
