My ex-wife loves this position, made her cum buckets. She's small with a skinny ass and it give me a weird pedo-like vibe. And I still get to bang her every now and then - good times!
Here ya go
There's a vid I uploaded too. There's a couple there
I was fucking my girl in a similar position last night but the one where you are on your feet instead of on your knees. I was coming down real hard on her and one thrust I went up to much and I came down balls deep right in her ass. She cried and her asshole bled. Be aware.
Yeah she shaved her head. She's growing it back out atm.
