Introductions discussion

I found this site two years ago and have been watching and dreaming (okay, lurking) since then. It has helped me bring up and talk about chastity with my wife, and last autumn we took the leap to buy a black CB-3000. Initially, she would lock me away for several days while I stayed home. Later, she worried I might cheat when traveling (I drive trucks, often gone for seven to ten days), so she started locking me before I departed and letting me out once I returned. So far, it is a huge turn-on, especially knowing my release could be three thousand miles away. My wife/KH has gotten into tease and denial. Now I am locked up constantly during trips, though there is no promise of relief upon returning; she can tease me for hours before locking me back in to head out again. The torture is wonderful. She gets great satisfaction as I please her orally repeatedly during the teasing process. I have not had a proper sexual release since July 4th. That covers my story so far, except neither my wife nor I care much for sissy feminization or crossdressing types of things. My wife/mistress/KH has threatened to invite her girlfriends over and make me serve drinks nude while wearing only the CB. She is also showing interest in cuckolding me. So what comes next?
