As it seems you like pain and pain is making you so horny.  

Video was hard to see, but from your sounds, my Wife and I think it must be a buttfuck.

My Wife can no longer take a cock in her ass but when she could, she always got on top in Cowgirl or Reverse Cowgirl so she could find the right angle for my cock to go up into her ("touching the bottom of her stomach" she liked to say).  And then she would do the fucking, and all I had to do was lay there and enjoy it to my orgasm. 

Her orgasm came as the result of having an egg-type vibrator in her pussy and a really cool clit vibrator, which was similar to a nipple clamp.  We would always buttfuck with me having a full bladder, which made my orgasms really good, the pressure, and then for the kink of it, I would unload my pee into her ass.  If she could hold it and get up, it was so cool for her to shoot out her pee enema.  If she couldn't hold, it was a glorious enema all over me.  Sometimes we both had full bladders, her peeing whenever she felt like it.
