I donno if you should be doin that while watchin your sister becuz then thought's of her may begin to pop into your head and you may not or may like it

Ummmm.....THATS WRONG DUDE

Don't let it happen again, pig.......

Its quite normal for a inter breeding town resident like yourself, your elder brother was doing the same to your mother and your dad was to your sister.

Ok this is so natural I support you kid keep it up there is nothing more hott then brother and sister love its so natural I once read a book about the connections brothers and sisters get can be stronger then they have with anyone for the rest of their life so just forgeting all that crap about inbreeding and shit your family will give you and just getting together will give you a happyer fuller life with a much more rewarding sex life. GOOD LUCK

I watched my sister in the bathtub a couple of times. I had to peek through a crack in the door frame, but I could get a little peek at her. She'd maturbate after when sitting on the toilet. The door crack was lined up perfect with her crack and I loved to watch her finger herself into an orgasm. I'd do the same to myself, but she never knew. How do you walk into a bathroom naked and not have her notice? She must like to show off - thats a good start.

well thats nasty

how exactly was she masterbating?..sounds interesting

she was in the perfect position for you to cum all over her face.
