I love when plump, mature hotties enjoy themselves like that! ♥ It would've been lovely to see her cum more than once. Then again, who knows what happened before... or after! Looks as if it wasn't her first ride on the underside. But there are some risks. I suspect her partner or somebody else was recording her.
I really would love to see her take those up her luscious, full ass! I can hear her moaning now. ♥ I'm sure the square one would be a memorable experience up there :O Actually, it sounds like I would love to do to my poor little love slave ass. :P Something about fitting a square peg into a hot hole... or something like that. *blush*
