Chastity and Pegging.
The thought turns me on intensely. Can't say that I am a fan of any of the chastity cages I have seen, but the thought of tying a man's cock up with rope while I am fucking him makes me squirm. There's something about the containment, the constriction, that thrills me. Ideally the cock I tie up is hard while I tie it up. I know it's not technically chastity, but that's where this picture takes me.
For the uninitiated, here is a tutorial! Thanks to Lady Juliana.
Now, see...this, this gets me going. I could be rubbing the pre-come from his cock all over the head of it until he goes crazy. I could do everything I could think of to see if I could get him to come with that rope on. Peg him, suck on the head, put just the head in my pussy and move it all around my wetness while we stand there and kiss ...yeah.
This...is fucking hot. I got off twice just thinking about this....!
