Keep him in chastity while letting him wear a strap on.  His attention Will not be on his release, but your orgasm.  The teasing is delightful!  The humiliation of him feeling the same motions, but using a substitute tool is beautiful

When you have guests over, dress just enough mistress- like to keep your man's attention, and keep him nervous.  Dangle something that looks a bit like a whip...  Your girl friends may notice how strong his devotion is to you!

While he is in a submissive state, walk around in his view letting your strap-on remain prominent and very visible.  It is an immense power trip.  Yours can remain erect much longer than his, and the suspence will drive him crazy.

Real love is making sure there is only one woman controlling a man's cock.  Only way to ensure that is a chastity cage.  Refusal is not an option
