She wants your fidelity

"I want your fidelity." She answers firmly.

This catches you somewhat off-guard and you find yourself asking, "What?"

She breathes deep and straightens her posture, as though summoning her courage. "When we got married we promised ourselves to each other, no one else. We said we would never cheat on one another; I was it for you, and you were it for me. If I'm going to do this, if I'm going to break that vow... I need you to keep it. Just because I'm getting fucked by five guys at the same time doesn't mean you get to go off and have a dalliance with some trollop."

She pauses and you take a moment to think about that. In all honesty there had been this idea in the back of your mind that if she was going to turn into some kind of super slut, you should be allowed to have a little action on the side too right? It wouldn't be anywhere near as much, but you would still get something. You hadn't expected her to demand you become some kind of cuckold...

She takes your hands in hers and continues. "I'll do it. I'll be this person that you want me to be, but know that I'm doing it for you! You'll get the job, the money, the power, and the respect; I'll help you get everything that you always wanted because I love you, and I want to help!" She raises her hand and gently presses her palm against your cheek. You look into her eyes and you see a pleading fear before she finishes. "But at the end of the night, when I've got the cum of twenty other guys sloshing around in my pussy, my ass, down my throat or on my face, I need you to promise me that I'm it for you. No one else. You get your whore wife, I get my faithful husband."

"That's my condition."
