Nothing. Not in public, at least.

"Oh! Oh god, I'm so sorry. It's... kind of on a hair trigger?" Nikki can't look me in the eye as they say it, and I can't seem to take my hand away as their massive rod keeps swelling under my hand. "Uhm, are you gonna... your hand, I mean?"

"Yeah, seriously, Matt." Joy's voice is muffled where she's stuck between Nikki's tits, hands holding on to the left and right of the firm orbs. "As much as I like it here, you need to take a step back or I'm going to suffocate between them."

"Sorry!" I yelp, straightening and taking my hand away from between Nikki's legs, feeling their enormous rod jump as if it wants to keep being touched. The feeling is surprisingly mutual. "I'm... oh man, this is weird."

"Damn, yeah..." Nikki's hands stay where they are - on my shoulders. They feel warm and strong and reassuring. "I, uhm, you guys alright?"

"Yup, everything good!" Joy chirps despite some evidence to the contrary. Thanks, shared senses. Not helping my mental state.

"Great! Because I need your help, guys." Nikki winces again as they look around and shuffles a bit to the side to keep Joy and me between them and a passer-by. "I, uhm, my downstairs situation is kind of... only getting worse. Can you, I dunno, act as a shield so one one sees?"

My eyes flick down, and the sight of Nikki's massive, throbbing pole stretching their pants has an immediate effect on me and Joy. In one word: Sploosh. If this keeps up, we're gonna need a shield ourselves! But what I say is:

"Of course! Hey, I've been there, more or less. Altough I wasn't quite as... conspicuous."

"You wore yoga pants and got a boner in public?" Joy twists her head to look up at me doubtfully, one eyebrow raised.

"No, I had boners in public that wouldn't go down. Now let's get Nikki to their dorm, alright?"

We look ridiculous. I don't even need to see us in reflections or on theoretical photos to know - Nikki pushes down their enormous rod and does their best to walk normally, but having lived most of my life with a cock, I know how hard that is. No pun intended. I myself do my best to block people from seeing my best bud's crotch, but their dick is just so big! It's tougher than expected, and I find myself distracted more than once due to certain reasons. Joy tries to help, but with her stuck to my hips, there's only so much she can do.

In short, it's everything but easy. And it's made more complicated by the fact that every time Joy or I brush against any part of Nikki's body, there is a little jolt that makes our pussy throb and Joy's nipples harden. It's not good for my state of mind. All the feelings that fluttered around in the back of my head stampede to the forefront. Nikki feels... nice. Strong and soft at the same time, and they're so tall! I never knew how much I was into people taller than me until my best friend turned into a muscular giantess. Shows that you learn something new about yourself every day.

Which doesn't help the current predicament at all. People aren't staring, but they definitely notice. If no one says anything, it's probably because we're obviously trying to not flaunt Nikki's erection to the general public, even though it's a sight to behold, if you ask me. But no one asks me, and I don't expect everyone to share my opinion anyways. Which is why we keep up our weird shuffling until we reach Nikki's dorm room.

"Phew, thanks, guys!" Nikki seems truly relieved as they open the door, ready to duck inside. "Gotta take care of this thing, it's relentless--"

"Youwanhelpwithat?!" I blurt out the words so fast that they are barely understandable. And I myself am just as surprised as the others that I said them.

"Say again?" One eyebrow raised, Nikki turns back to us, and I can't look them in the eye. Problem with that is, it draws my attention to a certain other part of their anatomy. It really doesn't help.

"Seriously. I know we talked about this, but you're really down this bad?" I can tell Joy is trying to sound exasperated, but she sounds more smug than anything. And when she continues, there's an uncharacteristic hint of insecurity in her voice. "Not that I'd be... you know... against it, but...?"

"Guys, I'm... I'm flattered and all, but... do you really... I mean, are you sure? About this?" Rubbing the back of their neck sheepishly, Nikki winces a little. "I don't wanna ruin our friendship by turning it into a FWB thing and fucking things up."

"So, uhm, I..." Man, words are hard all of a sudden. Just like Nikki's massive, juicy, throbbing... Okay, that does it. Maybe it's hormones, maybe it's magic, maybe it's my bi awakening, but I ain't gonna miss out on this. "Okay. I... Joy and me, we... we talked about how hot you are, how much we wanna jump on your dick, okay? And... and, if you're cool with... trying it? I know it's fucked, with Joy popping into existence attached to me, and you bulking up like crazy, and... and..."

"Hey." I feel Nikki's strong hand on my left shoulder, and their other hand on Joy's right shoulder. The touch alone, the warmth, it makes me shudder and Joy's nipples harden into throbbing little points. But after smiling at Joy for a second, they stare at me with an almost scary intensity. "I'm super flattered. And if you guys are really, 100% sure that this is what you want... because, if I'm being honest, dude, I've been crushing on Joy since I first met her. And I've been kinda crushing on you since that day in High School when you kicked Mark Allen's ass because he made fun of me."

"Oh, that's juicy!" Joy's voice is positively gleeful, and with consent from all parties established, she wastes no time and begins to gently run her hand along Nikki's impressive length. And I feel every throb, every lurch through our shared senses. "And I'm right where I wanna be, in the middle between you two..."

"Whuh..." And I still reel from the revelation. All this time, and my best bud had the hots for me. It's really damn flattering, actually, and something flutters in my chest as I move forwards, pressing Joy and myself against Nikki's body, rising my hand to their jaw to pull them down to us. To me. "Shoulda told me, y'know..."

It's the last thing I say for some time, Nikki shutting me up with their soft lips on mine as we make our way into their dorm room, shutting the door behind us. It feels electrifying, the pussy Joy and I share rapidly becoming drenched as it twitches and aches, begging to be filled. And while my hands are on Nikki's hip and the back of their neck, Joy keeps going for the much more juicy parts of Nikki's anatomy as she kisses our partner's neck. Joy's gentle caressing has turned into firm strokes, and I can feel Nikki's enormous rod strain under her hands.

Joy's left, meanwhile, is wandering upwards over Nikki's firm abs, feeling every smooth bump, then slowly trailing upwards under their shirt, ever closer to Nikki's soft boobs. And while Joy inches ever closer to our lover's perfect globes, Nikki and I keep kissing breathlessly as we make our way to their bed, and I find myself utterly dominated. Nikki is taller, stronger, and only too happy to take charge - and I'm all too happy to let them.

Their hands feel so strong on both our bodies, caressing with such care that it makes Joy and me shiver, our moans mingling as I feel liquid lust trickle down my legs... In all my time with a dick, I have never felt this needy, this horny, and when we bump into the foot end of Nikki's bed, they topple over backwards onto the mattress, Joy and I following so we come to lie on top of Nikki's powerful body, Joy's face in their soft breasts for the second time today and their massive shaft between my legs, pressing against our netherlips.

"Hnnghaawdh, it's... so big..." I can't help but move my hips, grinding against that juicy pole only separated from our crotch by Nikki's thin yoga pants, lustful tingles rising along our spines as Joy pushes us away from Nikki's body for a bit - for logistical reasons. "I... I..."

Joy frantically unbuckles the fake harness we're using and strips off her shirt, Nikki pulling off her own top, almost ripping it apart in the process. We have seen these incredible orbs once before, but now, we get to touch them. They feel soft, yet firm under Joy's hands as she sinks back into them, both hands roaming over Nikki's curves as Joy's lips wrap around one of their fat nipples. I can feel it throbbing between Joy's soft lips through our shared senses, but I'm much too preoccupied with the way my overly attached girlfriend's ministrations make Nikki's thick rod twitch and jerk against our pussy.

"F-Fuck, oh god..." Eloquence went out the window the second we entered the dorm room, but we're past words anyways. My hands are shaking as I undo the fly of my pants, and I feel Nikki's arm against my hips as they reach for their cock to free it in turn, their other hand digging into Joy's hair to show their appreciation for what she's doing. "I can't take it, Nikki... I need you... inside us..."

"Mmngh-hah!" With a wet slurp, Joy raises her head and lets Nikki's throbbing nipple slip from her lips, grinning up at their flush face. "I concur. That pussy destroyer needs a test ride!"

"'Pussy destroyer'?" I chuckle as I wriggle my hips to make some leeway towards baring our soaked snatch - and freeze when I feel Nikki's aptly named powertool slap against my ass cheeks. Twisting my head, I see Nikki is way ahead of us, their massive shaft freed and ready to go. Swallowing nervously, I breathe: "Oooh. Yeah..."

"Hey." Nikki's soft voice makes me turn back to them, concern on their countenance. "If you're not sure about this, we don't need to do PIV. Plenty of fun stuff we can do without me using the, uh, pussy destroyer for its designated purpose."

"I..." Angling my hips as I push my pants down a bit further, I feel warm air brush against the vulva I share with Joy, the heat radiating from Nikki's fat schlong getting stronger suddenly as it twitches and hits our swollen cunt. "G-gah! No! No, I... I wanna try it. I want to at least try it."

"Glad to hear it, because I definitely want that thing inside us!" Joy exclaims, hugging one tit each with arm and lying snugly in Nikki's cleavage. "But so we're on the same page, I might have a 50% share in that pussy, but if it gets too much for you, Matt, I concur with Nikki - then we stop and I get them off with my tits or something."

"Thanks, guys. Really, I appreciate it." As I talk, I rise my ass in the air to push my pants down to my knees, making Nikki hiss as the rough fabric brushes against their oversized rod. But now... now we're ready. "And I promise, if it's too much... I'll say something."

"Probably something like 'Oh god, oh fuck'," Joy grins, her good-natured ribbing barely masking the anticipation in her voice. She needs this just as bad as I do. "Now come on! Let's get this inside us!"

"S-sure..."

With my ass raised as it is, all I need to do is slowly lower my hips. I can feel droplets of femcum run down my thighs, our pussy twitching as it inches closer to to Nikki's towering rod - and there is scarily few inches before I feel the heat of their swollen glans. The length alone makes me swallow. Hard. But not as hard as Nikki's cock is. Apparently, my old strategy of dumb jokes in stressful situations also applies to having my best bud fuck the pussy I share with my girlfriend. Welcome to my crazy life.

"You alright, Matt?" Turning my head to look at Nikki, I see their worried expression. "It's just, you've been hovering like that for a bit. Don't **** yourself because you think Joy and I want this no matter what."

"They're right, I mean, I want this really, really bad, but..." Joy nods. I can feel how horny she is, how needy - just as needy as I am, actually, but Nikki's shaft is nothing short of intimidating. "Just because our neanderthal brain is going 'unga bunga smash', doesn't mean we have to. To be honest, you hesitating like that makes me thi--iiigh~!"

I couldn't take it anymore. Enough dawdling around - I only need to lower my hips a tiny bit further for Nikki to begin to spread us open. They feel... big. So much bigger than the copy of my dick lying at home. Which is perfectly average, thank you very much. It's just that Nikki's mighty hammer is so far beyond average, just like the rest of them.

"Oh. God. Oh god. Oh god oh god oh god." Joy is babbling, twitching, arms wrapped around the enormous orbs of Nikki's breasts as if she's holding on for dear life. "Ohgodohgod!"

"F-fuck, you two are... take it slower, Matt!" One hand on my hips, the other on Joy's back, Nikki's breaths begin to deepen with their rising arousal. "I don't wanna hurt you!"

"You're... not..." I pant, my jaw slack as I feel Nikki splitting us open, slowly making their way into your depths - but it's at my own pace. No faster or slower than I can take it. "It's just... so much..."

It definitely is. It's an experience. There is none of that disorienting double sensation of penetrating myself that I had when Joy and I used that living dildo, just a huge, throbbing, twitching pillar of hot fuckmeat splitting us open, and I can only just bear it, and judging by the wy Joy is writhing on top of Nikki, I'm not the only one. It stretches us so impossibly wide, going deeper and deeper over our folds, and it feels as if we're rapidly running out of room inside.

"Ghg!" And indeed we do. There is a bump, a hitch, an end, and we're completely full. Utterly and absolutely. And I'm running out of words to describe the sensation of this inhuman cock stretching us. "F-fffhh~..."

And the worst part about this? It's not even Nikki's entire length. Our hips are still separated by a few inches, but I feel Nikki throb inside of me, inside of us, and I feel almost unable to breathe. As does Joy, judging by her gasps and the fact I feel what she feels. It's dizzying beyond the lack of air - my actions have overwhelmed two people at once, our pussy twitching uncontrollably.

"Ffffuck, you guys... are you okay?" Nikki holds on to my hips, her thumbs right where my body and Joy's come together. I feel a light tremble in our friend's hands - they must be fighting to keep it together. Understandable, if it feels even half as good for them as it does for us. "I'm n-not hurting you...?"

With Joy still burying her face between Nikki's gargantuan tits, body twitching and shaking mine - not great for my mental coherence, but amazing feelings-wise - it falls to me to answer. And still, I struggle to find the words. Our masturbation session with that living dildo was intense, but this is on a whole other level.

"N-no, I... we... so glad we did... Nikki, we..." My mind is all over the place. I feel pleasure, I feel connection with my two favorite humans, I'm overflowing with emotions and I want to give voice to all of it at once. And I fail completely. But they way I put my hands on Nikki's wrists and roll my hips communicates it pretty well without words. I hope. "Hnnghoooh~..."

Who needs words when you can show appreciation by just moaning and beginning to move. All I'm doing is rolling my hips, back and forth and side to side, riding atop Nikki, but the way this makes them slide in and out of us a few inches and just stretch us is enough to elicit more shuddering moans from both me and Joy, who has stopped hugging Nikki's tits, instead hugging the entire amazon. Well, as far as her arms reach, at least.

"God... damn... Guys, you feel... incredible!" Grinding the words out between their teeth, hips bucking under us, Nikki clearly fights to hold on, doing their best to hold on, to hold back - even in my lust-addled mind, I realize their upgraded body is getting its first proper test-drive right now. An inflated dick, plus two giant tits Joy is enthusiastically motorboating... "Doing my... best here, but..."

It has to be overwhelming for them, too. And the realization sparks something mischievous in me, mixing with overbearing bliss. Nikki is so big, so powerful, making us feel this good, and still, they're at my mercy now, writhing under me, throbbing inside me, and one of the fundamental laws of sex is the existence of refractory periods. Let's see how fast I can cause Nikki to have one.

"Oh fuck!" I begin to move up and down, slow at first, but our snatch has already gotten used to being stretched by Nikki's girthy rod, so I can start to build speed. And Nikki is not dealing well. "Oh shit, Matt, you can't... you can't d--oooh!"

"I can," I gasp as I bounce up and down on a shaft that becomes harder and girthier every time I let myself fall down, filling the aching void deep within us.

"And he better," groans Joy from where she kisses her way out of Nikki's cavernous cleavage, making her way towards our lust-stricken friend's pulsing nipple. "I wanna feel you explode inside of us. I wanna see your face when you cum. I wanna hear you howl!"

With these words, Joy latches onto the nipple she hasn't worshipped earlier, sucking the thick nub between her lips to let her tongue play over it, one of her hands making its way between Nikki's and Joy's bodies to play with my overly attached girlfriend's own tits, the other propping Joy up. After all, why not torment dear Nikki a little more? Joy and I have more experience with our changed body/bodies, so we got used to these new pleasures more quickly. Let's take advantage of that!

Joy has started helping me as she sucks on Nikki's tiddy, moving her body in time with my hip movements, which helps considerably as the sensations running through us makes my legs shake and our pussy twitch. Still, as much as we shudder in delight, as clear is it that Nikki is getting closer to their climax pretty quickly. I can feel their swollen cock strain in ever shorter intervals. Their hands are digging into my hips, twitching and squeezing, pulling me down onto them as Nikki thrusts upwards haltingly, self-control quickly eroding.

"C'mon, don't hold back!" My breathless moans are interspersed by Joy's muffled squeals whenever Nikki bottoms out inside of us, delirious pleasure making my head swim. "I know how dicks work, you're about to let loose. Do it. Do it!"

"Cum inside of us!"

Joy raises her head just in time for Nikki's jaw to go slack, a deep, throaty moan issuing from them as they slam upwards and into us, the amazonian futa's eyes fluttering closed as they begin to lose their load, more and more cum blasting into our insides with every instinct-driven thrust. It's hot, and thick, and slimy, and it almost immediately begins to ooze from our slit, overwhelming our capacity with ease. And the sensation of being filled does the rest.

"Fffuck yes!" I can't see Joy's face, but I feel her tongue lolling from her mouth as orgasmic bliss ripples through us, my toes curling as I squeal in a way I would find embarassing in any other context. "Fill ush uuuup!"

As if we weren't already overflowing. But it doesn't matter, Nikki still has more to give, glob after glob pumped into us, until their climax peters out. Panting and sweaty, I sink forwards until I lie on Joy's back, who in turn rests on Nikki's muscular front. Their own labored breathing lifts the two of us with no trouble whatsoever - but this peace lasts exactly until Nikki has managed to catch her breath.

"So. This is how you two wanna play this, hm?" Uh-oh. In the blissful afterglow, I missed one rather crucial detail: Nikki is still completely, amazingly hard. No sign of a flagging erection whatsoever. "Then I hope you're ready for a full test-drive of the Pussy Destroyer!"
