Des：Yuichi wonders if his parents suddenly became brother and sister after they remarried. Rika is shy and quiet, but is actually a sadist. Yu intuitively believed that he was a masochist, so he trained her to be his toy. Upskirt footjob in my parents house. I got my moms attention and gave her a blowjob. He used it as a masturbation toy, sitting on his face and letting him lick it. She then calls her best friend to tease her brother and show him her and her boyfriend having sex!
