Male here, we enjoy mfm with a guy we know.
My 53 yo wife likes to ride our friend sitting upright kinda rocking on his dick while he holds her tits.
She likes him doing her from behind, after several position changes she always cums hard with him on top pumping her hard.
Can't begin to say how exciting it is when her legs are straight and her body goes stiff while he's pounding her and her head goes back. That gets him off, hell roll off her, she lays there catching her breath and kinda sweaty with his load oozing out. HOTTER THAN I CAN EXPLAIN. Then I start with her and she is friggin HORNY.
