I think my wife is doing something like that...an acquaintance told me he had seen her with a young black boy...when I fuck her she doesn't seem to enjoy it...and I notice her pussy more open...and my cock is small... .
If it was 1% of married doing it I'd be surprised. I don't envy anyone in these videos. I see them having fun and exploring the fun of sex. It's not just for babies these days.
Nothing wrong with that haha, that's the ideal scenario. My ex gf spent most of her free time on her back with her feet pointed and the ceiling and a BBC between her legs.
