Someone has been stroking their dick without my permission!  You know the rules - no cumming unless I say!  Now what am I supposed to do with that limp cock and those empty balls?  You were supposed to greet me with a hard dick and a huge wad of cum for my tribute, and now you have nothing to offer me!?  Shame on you!  There is only one solution to this.  Since I cannot trust you to control yourself and your filthy stroke habits, I'm going to have to lock your cock up in a metal chastity cage.

You aren't off the hook yet, Mr!  No no.  Once I have you all locked up, I'm going to tease you by stripping off my panties, bouncing my ass in your face and talk about all the filthy thing you COULD have done to me if you had stayed loyal to your stroke regime.  I bet THAT is going to make your cock hard again.  Too bad you have already blow the opportunity to shoot your hot wad all over me.  Now you will have to stay throbbing in agony as I gently run my tongue over your metal cage.  You can feel my hot breathe on your cock, but my elusive tongue won't give you a second of satisfaction.  It's awful isn't it?  Maybe next time you will remember to wait!  Now you are going to be waiting a very, very long time before you get to stroke your cock to orgasm, because I just did away with the key.  

Enjoy your sweet, sweet torment ;)
