[IENF-304] I'm currently training my brother. (Censored)

Yuichi wonders if his parents suddenly became brother and sister when they remarried. Rika has a shy and quiet personality, but she is actually sadistic. Yuichi intuitively thinks that he is a masochist, so he trains her to be his own toy. Upskirt foot job at the house where my parents are. I stole my mother's attention and gave her a blow job. He uses it as a masturbation toy and sits on his face and makes him lick it. Then she calls her best friend to tease her brother and shows him having sex with her boyfriend!
