My girlfriend and I have had a D/S relationship almost from the beginning. Recently, we have both discovered that talking about her taking a stud/lover for sex only is a huge turn-on for both of us. She is particularly excited at the idea of keeping me handcuffed, in chastity, with a choke collar and leash, on my knees and forced to ready her lover for her, then made to watch as he takes her. So far, it is just foreplay talk, but the idea that it might happen at some point keeps us both excited. Has anyone else tried this, and moved beyond the talk phase?
