Spreading her arse wide

Had a great time fucking my slut last night.. she said she wanted to go on top reverse cowgirl so she could bounce on me and play with her pussy at the same time.
I agreed as long as i could spread her arse wide with both hands as he rode my cock. She said yea ;)
Is that normal for a wife to agree to ?

She chnaged postion as she got tired and lay forward her head on the bed and her tits bouncing on my legs.. she started cumming on my cock as i started spunking deep in her used cunt.. her arse had never been so wide i was pulling it wide open with both hands! As she was cumming her arsehole was twitching getting bigger.

She crawled off me when we were both finished with my spunk running dowm her legs .. on the bed .. and all over the carpet as she walked to the toilet like a fat used slut
