My sister does not know, or at least must suspect. But the truth is that yesterday came drunk and I used his body as my sex doll private. Yes, I know I shouldn’t, but I really wanted to fuck. When it arrived, I was masturbating for the third time. I approached his room and she was asleep already with her clothes on. I touched to see if you would wake up, but he was completely drunk. Then I pulled on the skirt and I touched her pussy. I slipped the fingers, and I wanked. I took off my pants and I put my cock in her mouth. I pulled out and put my penis from her mouth as if she was doing a blowjob. Then I went to bed and I fucked before you wake up.
