Perhaps we were all just feeling particularly impatient to witness what was about to happen, but it had seemed to take forever for the change we all knew was coming. And come it did, if you'll excuse the pun. I was transfixed on my cock as it swelled outwards, quickly forming an outline in Rose's stomach that was getting bigger and bigger, all whilst she squirmed and squealed in a mixture of shock, pleasure and surprise.
I remember seeing Kellie's face too, forgetting of course that she'd never witnessed things happen quite like this before, her jaw dropped and eyes bulging almost more than Rose's stomach. Phoebe simply looked that wonderful mix of delighted and turned on she always got when this happened. She had started casually, but unconsciously I think, rubbing her belly as if she were remembering fondly when this had happened to her. The rush of pleasure hormones drowning my brain right now almost made me forget she was pregnant; for a split second I was convinced she was so big and bloated right now because she was full of my cum. Technically she was I guess, but that's besides the point.
"Oh god, oh fuck, it's so, so fucking much!" Rose cried, snapping me back to reality.
"You don't know the half of it yet," Phoebe said with a wicked grin. "You think you felt full before when you tried to drink his cum, but wait until he unloads inside you. You'll be even bigger than me," she laughed with a light pat of her belly.
Her words seemed to light a fire under Rose and she fixed me with a determined gaze.
"What are you waiting for, fuck me with that huge thing!" she commanded.
It would take a far greater man than I to ignore that request. As I pulled slightly out of her preparing to spear back into her as she demanded, I finally became conscious of just how tight her pussy was on my cock. Even with the rubber powder, her pussy was like a vice around my cock, as if a pair of strong, determined hands was gripping my cock and refusing to let go. Thankfully she was also incredibly well lubricated, her natural juices working into overdrive it seemed and I slipped back inside her with very little resistance.
I knew what my goal was now: to get as much of this cock inside her as possible. There were at least a good 5 inches or so outside of her to begin with, but she'd commanded I fuck her and that was exactly what I was going to do. I ploughed into her with as much force as I could muster, her whole body jolting as she steadily became more cock than woman. I watched with desire as I saw the outline of my cock move further and further inside her until I was almost between her breasts.
Each thrust pushed a moan of ecstasy out of Rose as if my cock were literally forcing it from her open mouth. To her left I could see Phoebe had reached around her prominent bump to her pussy where she was fervently pleasuring herself, living vicariously through Rose it seemed, and on her right Kellie lay with her hand almost fully cupping her own erection. All three of these women were so turned on, and for a second I let myself believe it was all me. I don't resent the fact that a pill makes me more attractive to them, don't get me wrong, but in the moment it boosted my ego no end.
After a few minutes of the hardest and deepest fucking Rose had ever had in her life (that much I can guarantee) I saw her gaze turn to Kellie's cock. Even in her sex drunk haze I could tell she was thinking something and she confirmed it when she got me to stop.
"I want... to change positions... please," she said panting.
I obliged of course, this was all for her after all. Pulling out of her, my cock never seemed to stop. It was probably only as big as it had been before, but coming out of her it seemed even bigger than usual. I watched the outline of my cock beneath her skin move back down her body until I was finally out in the open, and, it must be said, almost a foot further down the bed.
In a movement that was surprisingly spry for a girl that looked spent, she got herself onto all fours and backed herself towards me, her small but perky butt looking very enticing. She reached around to help guide me in, her hand looking and feeling tiny against me, and guided me back into her pussy which spread back open as before and took me in beautifully. She stopped for a moment to moan and shudder at the sensation before once again taking command.
"Kellie, I want your cock in my mouth," she said, "and Phoebe..."
"I know exactly what you're thinking," Phoebe grinned.
As we've established I'm a bit of an oblivious tool, so everything that happened next caught me off guard. I watched as Rose easily took all of Kellie's petite cock into her mouth and practically locked her lips on Kellie's groin. I saw Kellie smile and moan contentedly, remembering for a moment myself what Rose's lips felt like on a cock and not really being able to blame her. I didn't see Phoebe reach back for the bottle and pull out another pill.
"Open wide," she told Kellie, who did so without hesitation and quickly swallowed it down.
The next minute or so is a bit of a blur, but I'll recall as much as I can. It took a second to sink in what had happened, but I became immediately excited and for a second a little concerned. If my cock was almost all the way through her, having another one at the other end would be too much, surely? Before I could give it any thought though, Kellie's moans increased and I watched as her meagre cock began to balloon out into an absolute monster.
I watched in slight awe as Rose's jaw was forced further and further open by the widening shaft, imagining that its length must be snaking its way further and further down her throat. How she didn't gag is beyond me, but what really made me take notice was when I felt something brushing beside my own cock. It was impossible to see from where I was, but I would bet that had I been able to look, there now would have been two outlines beneath Rose's body, fighting for space. Whatever it looked like must have been good because to my left I heard the unmistakable sound of Phoebe cumming as she feverishly rubbed her clit with her eyes fixed on Rose.
Whilst I revelled in the sound of the beautiful mom to be, I suddenly felt friction against my cock as if something was pushing back and turned to see Kellie had started to facefuck Rose, her hands locked together behind Rose's head, grasping a little of her hair, and her hips thrusting rhythmically in and out. I matched the same at my end, alternating my rhythm so my cock didn't have to compete for as much space.
Rose was moaning ecstatically, although the noise was muffled by the large invader in her mouth. The noise seemed to vibrate through her body adding even more sensation to my frankly overstimulated cock, and I can only imagine what it must have felt like for Kellie who received the brunt of it. It must have been amazing, because her thrusts quickly started to pick up speed. She never usually lasted as long as me anyway, but this was moving to a fast crescendo. We all knew what we were there for though, and I felt Rose begin to brace herself in preparation. With an orgasmic moan of her own, Kellie thrust forward a final time and I saw her grip tighten on Rose's head.
"That's it Kellie," Phoebe cried, still masturbating furiously, "fill her belly with cum, fill it with all the cum you have!"
Kellie seemed happy to oblige, or at least I assume so because she kept going. She was past words at this point. I might not have been able to see our battling bulges, but I made sure to get a good view of Rose's stomach. It will never not amaze me watching a flat, pristine belly swell out, but it's maybe the knowledge of what's causing it that is the real turn on for me. Kellie's load was coming in thick and fast, quick bursts and spurts causing an erratic but almost rhythmical swelling, just a little more each time making Rose's belly swell more and more, getting rounder and rounder and closer and closer to the bed.
I hung on for as long as I could, but the pressure in my balls combined with the sight I was seeing before me became too great to ignore. Phoebe must have noticed too, because she fixed her eyes back on me.
"Give her your big load too Jack, make her huge, make her twice as big as me!" she demanded.
I always do as Phoebe asks.
I pulled Rose's hips back towards me and thrust deep inside her one last time, almost pushing Kellie out it seemed as she was moved back. My own ejaculation came on like a flood. It felt like it was constantly flowing like a burst fawcett. Rose pulled away from Kellie, her cock falling out of Rose's mouth and landing like a stunned snake on the bed, and let out a scream of euphoria as she sat upwards. Instinctively I grabbed her and held her upright as my load filled her up.
From here I could see everything. Already her belly was starting to dip slightly with its sheer size and it was quickly reaching and surpassing Phoebe's pregnant with quads. I stole a reach around and placed my hand on her expanding mass, marvelling as it continued to grow and almost dwarf my hand. Phoebe was practically losing her mind with lust, and it felt like there was a real danger she might just say 'to hell with it all' and mount Kellie, but somehow she held back.
Kellie had just about come around at this point and was moving herself off the bed, Rose's ever encroaching belly taking up more and more space as I continued to fill her up. Holding her up was becoming more and more difficult, but I knew I didn't have much more in me so didn't need to last much longer. With a final groan I deposited the last of my seed in her and let out a sigh of both relief and pleasure.
Kellie was by her side as I gently let her go and between us we laid her down on her back on the bed. She was quite the sight to behold. Her massive round belly stuck out maybe a foot and a half to two feet in front of her and was taking up all of the front of her lower torso and some of the sides too. Her legs were being kept apart by the mass of stomach in the way and if I had to guess I would have sworn her petite boobs had grown a little too. Her hands rested atop it, making small little twitching movements as her body clearly tried to decode the amount of pleasure she was in.
