Wife Jerking Off

My ex-wife (M) and I were very compatibable sexually.  One thing M enjoyed doing was using my hard cock to masurbate with.  Sometimes she would lay on her back with me kneeling between her legs and she would grab my cock and rub the head against her pussy lips, she would guide the head of my cock up and down her pussy till she got real wet then let just the head slip slightly in and out and use it to stimulate her clit.  Sometimes she would get in doggy style position and reach back to rub my cock against her pussy and then guide me in for a few quick thrust. I loved this not just because it felt good but I got to view and tease her ass. This was always pleasurable for the both of but the best was when she would have me lay on bed and she would sit on me and grind on my hard cock, Damn I'm getting hard just thinking about laying there looking up at her tits as she grinds on me. 

After she would cum and both her pussy and my cock were nice and wet she would reach down and start jerking me off. From both our positions it appeared as if she was jerking herslf off. She would say to me "you like watching me jerk off my big hard cock"  of course I would say yes baby you have a great cock, I love watching you jerk off.  She really got into it and that only made it better for me hearing her talk about her cock and cumming on me. She would move her hips and even had facial expressions of pleasure, as she could tell from my reaction she knew exactly when I was gonna cum and shoot her cum all over my chest.  She would sometimes have an orgasm at same time and then colapse on me and massage our fresh cum with her tits all over us.
