Strapon Fetish
Another thing that drives me crazy is when I feel hands reach around the side of my hips and pull me backwards while she is thrusting forwards. You feel a complete loss of control when you're being taken this way. I've watched a few strapon videos where the sub is pegged in sex swing, and I'm very curious to try that because the Domme can literally impale her sub on the dildo easily using gravity and inertia. A good Domme knows that what submissive men really need is a hard, deep drilling, so she uses her entire body to drive the point home. You may be a little sore afterwards, but it's a good kind of sore that makes want to come back for more.
So in a sense I have a hips and thighs fetish. When I see strong, powerful hips on woman in the back of my mind I'm thinking about what an amazing fuck she could deliver. It's strange how my mind works.
