So I stumbled upon this preview:http://www.sweetfemdom.com/index.php?vid=MzMwMw==

 Typical hot sissy + lover + Mistress scenario except at the very end, the stud is turned into a strapon toy and even made to suck off sissy's cock. Never saw this before and must say, quite hot! It's like a sissy factory: invite stud > team up with him to dominate sissy >turn him into your bitch boy > team up with sissy to dominate him > voilà, you have a new sissy. :)
