Monica is mocking you

“…cock is so much better isn’t it, huh slut?” You hear Monica’s voice through the door, as well as a rhythmic slapping sound you assume is the sound of her hips hitting Amy’s as Monica thrusts into your girlfriend. For a moment Amy struggles to respond through her moans before gasping out a sentence. “You’re -ah!- s-so mean to… fuck! M-mean to him…” she protests, not directly denying Monica’s claim.

“C’mon slut, it’s true isn’t it? Why else would you be so eager to get bred by me if it wasn’t because that cuck isn’t properly satisfying you?” Monica presses, as you hear the slapping sounds increasing in rhythm and volume. Just from the noises of their two bodies impacting each other, you can tell Monica is giving Amy the fucking of a lifetime, one that you could never personally give your girlfriend.

Amy’s moans and gasps of pleasure increase in volume and frequency, matching the slaps. You can tell the next sentence she chokes out is significantly harder for her to get out. “F-fine! You’re b-better! Fuck! So -ah!- s-so much b-better!”

Monica chuckles in response to your girlfriend’s admission, clearly satisfied she got your girlfriend to admit the truth. “Good girl.” She purrs smugly. “Now take your reward!” Monica suddenly exclaims, as you hear the slaps suddenly get even louder.

“Fuck! Y-yes! Cum in -ah!- me! Breed me!” Your girlfriend exclaims happily in between moans. “I’m c-cumming again too!” She moans. Somehow, this surprises you. You’ve never been able to make Amy cum from penetrative sex, only making her cum by giving her oral at her request.

You hear a body hit the bed, which you assume to be Monica resting on the bed after finishing cumming in your girlfriend for a second time today. You take this opportunity to carefully make your way back to the couch in case one of them suddenly exits the bedroom. You sit there for a few minutes before you hear the bedroom door open. Turning your head to the noise, you see a freshly bred Amy walking out of the room, her legs shaking, followed close behind by Monica, with a smug expression on her face, both still naked.

“‘Sup cuck! Enjoy listening to the show?” She asks. Before you can respond Amy turns to Monica with a gasp and a fake expression of outrage on her face. “Monica! You are so mean!” She says, giving the dark skinned Amazon a light slap on the chest. “Don’t worry about her baby,” Amy reassures you as she turns to you, “she’s just messing with you.”

“Haha, yeah no worries.” You say meekly, accepting the teasing. What other choice do you have?

Monica sits on the recliner next to the couch, her half erect cock swaying in the air. Even partially flaccid it looks to be nearly two times larger than yours. Amy, instead of sitting in the open spot next to you however, kneels in front of Monica, and grabs the large cock with both her hands as she brings it towards her mouth. “Uhm, what’s going on now?” you ask, confused.

Monica looks at you, that same cocky look on her face as one of her hands moves to the top of Amy’s head, guiding it as Amy licks and sucks on her shaft and head. “Your girlfriend is gonna clean my cock off as I explain a couple things to you two.”

“Oh uh, yeah of course.” You agree, as though it was obvious what was going on.

“So firstly, I basically have a 100% success rate with knocking up my mares on the first attempt.” Monica explains. “However there are still a few things you two need to do to ensure a higher success chance.”

You anxiously glance down at Amy, trying to gauge her reaction to what Monica is saying. While she is still devotedly cleaning the massive dark futa cock in front of her with her mouth, your girlfriend also appears to be hanging on every word Monica says.

“Firstly, you two need to refrain from sex with each other for at least two weeks. That way we ensure it’s only MY seed knocking Amy up, and not… you know. Yours.” She says despairingly to you.

“Two weeks? That’s ridicu-“ You begin to protest, however you are cut off by a sharp look from Amy, as she glares at you and asks you, “Babe do you want this to work or not?”

You meekly stutter out an apology to the both of them, asking Monica to continue explaining her guidelines.

“Secondly, like I said earlier, I basically have a 100% success rate, so Amy is probably already knocked up. However, if for some reason Amy doesn’t get pregnant, I’m willing to do a follow up breeding session at no further charge.” She explains.

“What? Charge?” You ask, confused.

Monica grins cockily at you, as Amy continues to clean her cock without pause.“Yup! Lastly, that brings us to my charge for fucking and breeding your girlfriend today. It’ll be $250.”
