I love sissies with low slung balls. I love to hear them slap in rhythm, I love to have them in my face while on the bottom in a 69, but mostly I love to watch them tighten up just before she cums in me. So nice.
Love mine hanging and used as a handle to stuff me deeper with cock!
I find this one INCREDIBLY erotic. I am a nylon fan, so any image of a girl (regardless of anatomy) in nylons, looking so cute and feminine gets me going. Of course add on the submissive foot posture, and that is icing on the cake.
