And the Pussy Destroyer will do it's thing.

Before either Joy or I can answer, we find ourselves lifted bodily by Nikki's powerful arms, their cock regrettably slipping out of us. The massively muscular futa then turns us around, and shortly after, we find ourselves face down, ass up on the bed, quivering, snatch leaking cum and facing Nikki as our heads push into the mattress. It takes only a slight angling of my head to look into Joy's face, and I see the same anticipation on hers that I know is on mine.

"Oh my god!" My attached girlfriend gasps, tits pressed against the bed and throbbing nipples digging into the soft sheets. The stimulation makes us both shiver. "I didn't expect..."

"Yep," Nikki grabbing my hips with her powerful hands interrupts Joy pretty effectively, particularly with the enormous cock slapping between my cheeks almost immediately afterwards. "Me neither. I thought I'd need a break, but look at that... I don't."

"A-and you think that's because--" I can't finish the sentence, because Nikki is flipping the script on us, prodding their swollen glans against our equally eager pussy.

"Dunno--hrnh!" Once again, Nikki drives the breath from both Joy and me simply by filling an entirely different part of us. "Gotta be the potion. Apparently my ideal body has great stamina. And after your little stunt just now, I wanna see if you can say the same."

"We're sorry--" I begin, thinking that maybe we did go too far, but Joy interrupts me.

"No, we're not. We've been baaad. We need a good punishment with the Pussy Destroyer!"

"Alright then. Bite the pillows, girls, because here I go!"

That's all the warning we get before Nikki begins to move. And both Joy and me are entirely unable to keep our voices down - I'm surprised how different it feels to be the bottom, the one being conquered ruthlessly, the one rocked by powerful thrust after powerful thrust. Nikki doesn't give us any time to deal with the ****, using our pussy much like we used their cock, driving our faces into the mattress again and again, even making Joy's perfect pair roll back and forth, adding to the stimulation overwhelming our faculties.

Back when we rode Nikki, I could slow down if it got too much for me or Joy, thanks to our shared senses. Now? Nikki can only go by both our reactions. And their goal is to completely break us. To turn us into whimpering, twitching messes. And we're well on the way, with me shaking my hips uncontrollably to slam back against Nikki's crotch whenever they drive their battering ram into us, loud claps of skin on skin filling the room. Even our words are quickly devolving into breathless babbling.

"Oh god oh fuck yes!" Joy is clawing at the sheets, holding on for dear life - me, I have control of my legs and am thus a more active participant. Joy doesn't even have that. Which doesn't diminish her enjoyment at all. "Fucking break us!"

"Oh, I'm... gonna." Grunting between thrusts, Nikki leans forwards until their hands need to go from my hips to the left and right of Joy's respectively my head, grabbing one wrist from each of us, and begins piledriving into us. I didn't even know my back could arch that far, but giving Nikki the perfect angle is apparently sufficient motivation. "This is... payback. You little... fuckers!"

The bedsprings creak as Nikki roughly takes us, and the dim part of my mind still forming coherent thoughts is amazed how much I'm enjoying this. The rest is just enjoying the ride. Immensely. Nikki just keeps driving the breath from our lungs in deep, heartfelt moans, and through half-lidded eyes, I see Joy mirror my expression, stare vacant and lustful, our fingers scrabbling and our arms twitching in Nikki's powerful grip. Our free hands find each other, fingers intertwining as Nikki pounds us.

Nothing matters right now, nothing except that perfect pillar of fuckmeat driving us towards climax, driving us insane with pleasure. Shuddering and mewling, I feel waves of pleasure ripple through me and Joy, and Nikki just keeps going, using magically enhanced muscles to never falter in their ****. It's almost unbearable as bliss whites out everything else in my brain, but lucky for Joy and me, we have no say in this; we are Nikki's fucktoy, and they're making sure our pleasure barely diminishes after our first climax.

"Gh... gh... gh..." My eyes roll up in my head as strangled noises make their way from my throat, tears of bliss trickling over my face just as femcum and jizz trickle down my legs.

I don't even care anymore. All I know is seemingly never-ending climactic bliss racing through me whenever Nikki fills us to bursting. And Joy is not exactly making it better - I have to deal with my own pleasure as well as every last ounce of hers, plus the stimulation from my girlfriend's tits... It would make any man weep. Nikki just keeps the rhythm going that unravels our minds, tireless, relentless, bearing down on us with their considerable weight, pressing their mountainous tits against the backs of our heads. I can feel one fat, puckered nipple dig into my cheek, but I don't even have the presence of mind to turn my head and suck on it.

"How you like that, huh?" Wordless squeals and groans are all they get in return. I mean, what did they expect? They wanted to break us, they broke us. In record time, no less. "Then you'll like this even more!"

Letting go of our wrists, Nikki hooks their arms around my legs, one hand supporting my body, the other Joy's, and simply lifts us up. Fucked limp and loose, all we can do is lean back into their pillowy tits as they keep pounding us, from a different angle now, but with the same mix of sheer strength and skill that sees us bounce up and down on Nikki's steel rod, thick juices squelching out of us as we hold on to our conqueror's arms haphazardly.

It feels different once again, being fucked like this. The massive cock stabbing at our core from below fills us deeply, hitting different spots, all of them amazing. Joy and I can only twitch and moan at this point, and Nikki still keeps going, not caring what they are doing to our minds. We aren't equipped to keep up with this sex goddess. I don't think anyone is.

"Fuuuck. You pussy's... perfect," Nikki grinds out as they lift us up and drop us onto their straining rod, making Joy's tits jiggle wildly. "I think I'm about to... pump you full of my second load. Get fucking ready!"

Our answer is in no way coherent, but no less enthusiastic. A hot load of potent baby batter filling us sounds like the exact thing our instinct-driven bodies need right now! But even though Nikki said they're about to blow, they still keep thrusting... and thrusting... and thrusting. Every time they bottom out, sparks dance in front of my eyes and overwhelming bliss whites out everything else in my mind. Every time they pull out, the aching emptiness makes me want to cry, but we are full more often than we are empty.

"HrrrnnnaaAAAAH!" The bellow that finally rips from Nikki's throat as, without warning - or rather, a long delay after the warning - they explode inside us. "Fuck, fuck, fuck!"

And it does feel like an explosion. Like a punch in the gut. Only the fist is made out of pure, unadulterated pleasure with the **** of thousands or even millions of years of evolution behind it. My mind seems to shatter, time loses all meaning, only the climax is real, pulsing with every thick glob of cum cannoning into us... and pulsing... and pulsing...

"Uuugh..." When I come back to, I am resting in Nikki's arms, and Joy in mine. And wouldn't you know it, my girlfriend is fast asleep. "Wow, that..."

"That was a fucking success, don't you think?" Nikki sounds smug, and with good reason. Joy and me, cocky as fuck, started a fuck contest and damn, did we lose. If you can call that losing. "I don't know if this is gonna be a FWB or a poly thing, but... I'm glad you stumbled onto my dick, Matt."

"You know, if you ever worry the potion affected your mind, don't." Even though it's meant as a dig at Nikki, it doesn't sound like it. It would be hard to manage that, with me using my best friend's gigantic mounds as pillows. "You're still the same dingus, with the same inappropriate jokes at inappropriate times."

Nikki just chuckles and kisses the top of my head, making me blush and snort. Maybe the potion did something to their mind after all.
