[Chinese]SONE-681 "Too innocent, being led around by an older man!?" Her younger sister made me lustful, and I secretly kept having sex with her. The worst kind of guy is me. Ito Ruka

I decided to teach her younger sister, Ruka, how to study.Even though she is called a female student, she is still a child, innocent, and cute.She seems to have little knowledge about sex, and she shows off her panties without any protection, and shows through her legs...What's more, my breasts are also big for the year.Even though I know it's her sister, I see her as a 'woman'.When I realized it, I was kissing my young, soft lips.Despite Ruka's surprise, she was enthusiastically devouring her tongue.Probably the first kiss.Perhaps because of his lack of sexual knowledge, he still has no grasp of the situation.There are few practices that make you hate me...Is this so innocent...My penis was erect, the more I realized the worst thing I was doing.
