For me I love cowgirl because my girl has GIANT bOObs that need to be abused.
Reverse for me ..I love looking at and smacking that ass
What about Cowboy or reverse Cowboy?
It all depends on how she moves, how we fit, and the angle of entry. The more painful the curve going in and along the shaft, the better.
Although, truth be told, I prefer her side-saddled on the couch.
