Unlocked from chastity for a sloppy throatjob, not allowed to cum and locked back up

My sub had been caged forever, so I figure I’ll give him a *taste* of freedom. I strap him to a chair – wrists bound behind, ankles to chair legs, blindfold on – then unlock his cock. I proceed to give him a wet, sloppy throatjob; I slobber and deepthroat his cock while he can hardly believe it. I make him think this might be the day he actually gets to cum. But sadly (for him), I stop when he’s getting close. I then pull out a bottle of lidocaine numbing spray and absolutely coat his cock in it. His erection quickly fades to half-mast as he goes numb. I slide his cock, now nicely limp, right back into the chastity cage and lock it up. “Throatjob time is over!” I tease. I leave him there, cock numb and back in chastity, dripping with my spit and the memory of what almost was. He got the thrill of feeling my throat, but not the satisfaction of an orgasm – the perfect cruel tease. (Don’t worry, I enjoyed myself plenty, which is all that matters!)
