Yes

"I'll make you a deal and only if you agree to my terms will you be allowed the pleasure of cumming."

"Yes Mistress anything please, just let me cum Mistress."

At this point your absolutely **** to be given permission to cum no matter what Doe demands. So long as she holds up her end of the deal of allowing you to cum thats all you care about. You have to fight the urge of simply just stroking yourself raw as you feel the pressure building up wanting nothing more than permission to cum. It's when Mistress leans over, her hand still working the dildo in and out your ass teasing your prostate, to whisper in your ear.

"You may have permission John so long as you lick up every last drop that shoots out on the floor and I don't wanna hear any objections. I've read some of those stories you had saved where after cumming most men no longer have the desire to continue submitting. We won't have that problem will we though?"

Admittedly this won't be the first time you will taste your own cum but it would be the first time you aren't eating it directly from the source. Since all the other times you've eaten your own cum have been from when you jerk yourself with your legs overhead cock pointing directly at your wide open mouth. Though you don't won't to disappoint Mistress Doe and you certainly want to cum so without much choice.

"Yes Mistress Doe if earning the right to cum means licking it up then I'll gladly do it."

Not bothering to answer your cries of submission instead opting to just take your cock in hand stroking all the while continuing to thrust the dildo in time with every stroke. You can't help but feel overjoyed at the sensation of having your gorgeous girlfriend turned dominatrix as she stimulates your cock and prostate. It's when you start moaning that she starts teasing you.

"Thats it my **** boy I know your loving every second of this. I bet your wishing you had confessed your desires to me much sooner. The sound of your moans it's music to my ears so come on do it, I want you to shoot that load so you can lap it up like a dog. Come on stop making me wait and shoot that seed all over the floor, so I can witness you eat that cum like the cumming loving anal slut you've hidden yourself to be."

The pleasure is too much as I feel the pressure in my cock and when I feel that pressure releasing I let out an animalistic groan as I my cum shoots all over the floor beneath me. At the moment of release I can't help but thrust back into the the dildo as she keeps stroking my cock. I feel near to collapsing as after multiple spurts I've finally stopped cumming as without even thinking I feel my body moving almost on it's own. I'm positioned on hands and knees dildo sticking out of my ass almost comically my face above my own pool of cum.

After about a second of staring at the large pool of my own cum almost in a daze a lean my head down and began lapping at it eagerly. With every lick in the back of my head I'm disgusted and ashamed of my current situation, yet another part of me the part that tells me to keep licking knows that this is my place. Every lick of my thick salty cum further cementing my submission to my Mistress as slowly I start to enjoy the feeling of my cum coating my mouth before being swallowed down my throat. It isn't long before I've licked up all the cum on our bedroom floor as I look up at Mistress standing above me.

"Wow I must say I'm surprised at how eager and willingly you devoured your cum John but you will be glad to know that you have pleased your Mistress which is why I have another reward for you."
