One time when my sister was taking a shower i cracked open the door and when she got out of the shower I saw her breasts. Now all I ever think about when I jerk off (which I do about 5 times a day usually to hentai) I think about having sex with my sister or my mom. Is this normal. Also I found one of my mom;s vibrators and I stole it and sometimes I jerk off while I put it into my butt. Is this normal too?
