Give her the first cum load

You grasped her body tightly as you felt her body relax in your grip, signaling to you in a nonverbal way that she had relinquished control over herself to you and you were free to move and use her body as you saw fit. A side-effect, perhaps? Not the way that he always seemed to be in control of things but you weren't one to argue. She wanted to be your wife and, for the next 7 days, she was for all purposes yours.

She was very loose as it were, her ass being primed by the ass plug that you had her wearing for the past week, but it still was no where near as big as you were when you slid your cock into her for the first time, eliciting a moan and a small yelp of pain. She had tears in her eyes as the sensation of a man entering her body for the first time made her realize just how different things were. Still, as she breathed, you were patient, tender, and waited for her body to adjust to you. Even though only the head of your cock was in her, you felt her body warm itself around you and after a few moments, she leaned back and begged you in a barely audible whisper to "fuck me like those other bitches..."

You were too occupied to really care at this point how slow or fast you were going to take it, you wanted to make sure that she felt the pleasure of having you in her, the only man that would be in her from this point forward, and you made it known to her among thrusts that she was your cumsleave, no longer your boss, and she would be wise to start accepting this as fact. She moaned and grunted, her body still trying to get used to your shaft entering her in the rear and when you thrust as deep as you could (only halfway too!), your head pressed against her prostate and caused her to instantly cum, a squeak escaped her lips and a spurt or two of cum coated the bed in front of her. A few moments later, you came in her ass, dumping your first full load into her and she came again, squirting and her little nubbin of a penis barely coughed up anything except clear fluid.

"Oh baby, you fucked me good..." she whispered after you pulled out and gingerly placed your hands around her waist and pulled her close. Your cum leaked from her body but barely, another side effect being that her body rapidly absorbed the cum.

"What should your name be? Can't just call you 'boss' anymore..."

She took your hand and placed it over her waist as she snuggled against you and pressed her small breast against your body. "You are making me...what do you want to name me?"

You thought for a moment and laughed a little. "I loved Monica growing up. How about that?"

She nodded. "Monica it is..." She placed her head down on your chest.

The two of you laid there for a few moments before you looked down at her face as she looked at you. "You okay with this, though? I'm going to be able to change you and what you look like for the rest of your life. You won't have control over it."

She sighed before raising her head and giving you a kiss. "I gave you that trust when you gave my the first dose without taking advantage of me. Besides, if this helps you in anyway, I'm all for that." She rested her head back down. "Besides, just promise me that you won't make any more black bitches, okay? I don't mind those skank-ass white girls but no black woman comin' between me and my man..."

Interesting, mental changes already happening? You made a mental note before sleep overcame the two of you.
