I think we had a similar conversation regarding mental bondage. It is indeed a very hot aspect of D/s. Online or in real life, at some point comes the command...

On your hands and knees.
Now lower yourself onto your chest and shoulders and grasp your ankles.
If you let go for any reason... it stops.

"It" of course is always something pleasurable, but difficult in the face of being self-restrained.


Yeah! That's the ticket!
