Give her a proposition...

You gaze down at Jennifer and consider your options.

"So you want more of my cock?"

Jennifer looks up at you, almost teary eyed. Her wanton desire to wrap her lips around your cock is apparent in her eyes. "Yes!" Jennifer gasps out, her eyes wide with complete devotion and submission. "Yes David, I'll do anything you ask, just please, let me suck on you off!"

Her desperation is apparent, and you decide to test how far she is truly willing to go.

"So you'll do anything?" you ask her, a greedy glint in your eyes.

"Yes, David anything!"

"Alright...I'll make you an offer", you say. "You can suck my cock - and swallow as many of my loads cum as you can, but you must become my oral sex ****. From this point on, I set all the rules. You will not act unless I tell you to act. You will not suck unless I tell you to suck. Your entire purpose in life will be to service me and my cock.

She looks down for a moment, the idea of giving her life in devotion to you giving her pause to think. She would essentially be giving up her life, her job, her friends and family, her reputation. She'd be jeapardising her daughter's future - she'd be giving up everything just to suck you off every once and a while. A whole lifetime devoted to being used as a blowjob dispenser.

"David...I don't know...I want your cock in my throat more than anything, but..."

You can see the hesitation on her face, so you decide to sweeten the deal for her.

"Alright Jennifer, how about this? If you agree to being my full time **** right now, you may suck my cock for as long as you want for a full 24 hours. You get to swallow as many loads as I can produce until tomorrow morning, and I wont try to stop you."

You see her eyes light up. The promise of a full 24 hours of having your cock to suck on is clearly a strong incentive for her to agree. She begins to get antsy, clearly loving the idea of being a your personal cock sleeve.

This deal works out well for you. Seeing how eagerly she sucked your dick during your 10 second test you can only imagine how well she will service your cock given a full day. Plus, thanks to the amazing powers of Blowjob Universe, you can cum as much as you want and get hard instantly, and she can suck you off without getting lockjaw (unless you want her to get lockjaw. This is YOUR universe after all!) If she refuses the deal, at least you'll get to see her on her knees, pitifully begging for the opportunity to suck you off some more, which is always hot. Either way you win.

"However!" You continue. "Once that 24 hour period is up, you only get to suck my cock when you have pleased me, or when I explicitly instruct it. After the first 24 hours as my new personal cock sucker, I own you. I can fuck you however, wherever, and whenever I want. I tell you how to dress, what to do around the house, how to behave, how to speak. I can use you however I want. Your body is mine. My cock and my cum is your reward. Do we have a deal, Jennifer?"

She remains on her knees, considering becoming your personal mouth whore. She clearly loves the idea, as you can see the desire in her expression.
