[SONE-681] - [Limited quantity] "I'm too naïve and obedient to an older man!?" Ruka Itoi with 3 raw photos

I decided to teach her sister, Ruka, to study. Even though she is a female student, she is still a child, innocent, and cute. - It seems that her knowledge about sex is shallow, and she is defenseless and panchira and transparent bra. Moreover, the bulge of the chest is large for her age. Even though I know it's her sister, I see her sister as a woman. Before I knew it, I was kissing her young, soft lips. Despite Ruka-chan's surprise, she was crazy and devoured her tongue. Probably the first kiss. Perhaps because of his shallow knowledge of sexuality, he seems to have not grasped the situation yet. There are few pretenses that I don't like ... Is it so naïve? My penis was so erect that I realized the worst of what I was doing.
