I love watching my wife ** on her pillow!

During heavy foreplay and some drinking - I can talk my wife into rolling over onto her pillow. I put it up between her legs and and she mounts it like she is **. She really likes it when I rub her bottom hard and fast - pushing her down into the pillow. Sometimes if she is taking too long to ** I'll slide a ** between her clenched ** cheeks - heading for her ** hole. I barely get there and BAMM! she will ** then!.
Actually - my wife has her loudest - strongest - most grunting and growling ** when she is rubbing something: my thigh, her pillow or often on top of me rubbing my stiff ** which is folded up on my stomach......I think she is enjoying very firm and direct contact with her **. But, man it makes her **!
I'm pretty sure this goes back to her adolescent years - when she discovered the joys of masturbating by rubbing her ** on things....like folded towels in the family bathroom.
The thing is - my wife while being very slim and attractive - looks like a modest office worker, who helps out in sunday school classes. She is very proper - never uses bad language, etc.
But - get her in bed - and she is like a pricey **! Loves to swallow, and is happy to do anything but **....although she likes to lick and be licked there!
