"Sorry but I've got to see how big this thing has gotten," Phoebe said, pulling herself upwards and away from my cock, moaning in pleasure as she did.
She kept going and going and so did my cock. I'm pretty sure my limit had been fifteen inches before, but this was clearly beyond that and thicker to boot. If I had to guess now, I'd say I was nearing twenty inches, otherwise known as way too damn big.
"Holy fuck!" Phoebe repeated. "They weren't kidding when they said those pills were more concentrated! And look at your balls," she said, suddenly fondling them and drawing a gasp from me. "Fuck, I'm gonna be house sized from draining these things!"
I was suddenly overcome with the powerful urge to want to cum, no to need to cum. But not like I was about to cum or anything, oh no. I somehow knew I needed to be back inside Phoebe in some way before I'd be able release a load from this thing.
"Please," I told her, "please I need to be back inside you!"
"You don't have to tell me twice," she grinned as she stood herself back up so she could start to lower herself back down onto me.
Even though I'd literally just watched her pull herself off me, it looked near impossible that any of my obscene cock was going to be able to fit inside her now. Indeed, she had to take it slower than usual, but bit by bit she got back to where she was, hovering above my cock with a good six inches still outside of the warm, velvety confines of her pussy.
"Wow, I'm really gonna have to fuck this thing to get it all in aren't I?" she said with a wicked glint in her eye.
I didn't protest. Normally I might have, if only to beg caution, but it almost felt like there was something animal about me now. I just wanted to fuck her and fuck her and fuck her until I came. She gave me my wish as she started to lift herself and throw herself back down on my cock. To have any chance with this thing, she'd have to break through her cervix again. Last time we'd done that though, I'd been smaller both in length and girth. She'd managed it before and somehow I knew she would again. And that was good, because I wanted to be in there, to cum in there.
The way she moaned normally had always been music to my ears but there was an added intensity now as she used all her strength to pleasure herself with my monstrous cock. With a look of manic determination, she dropped her whole body weight down on my cock and finally I felt the pressure on the end of it give way. The remaining six inches pushed their way inside her and I watched as the stretched outline of my obscene cock moved up to between her breasts, just in front of her ribcage.
"Oh my fucking god!!!" she screamed.
She had every right to. There was no natural way in the world that any human was supposed to experience what she was experiencing right now. Indeed, if not for that wonderful rubber powder, she might not have been able to survive this, let alone enjoy it! None of this was what was going through my mind however. All I could think was 'cum inside her!'
I grabbed her hips and started bucking upwards with as much force as I could, pulling out only ever so slightly before roughly burying myself back inside her each time. Each thrust caused her whole body to jostle, her boobs in particular bouncing about invitingly above me. The urge to grab them was strong, but I needed my hands on her hips to make sure she was getting the fucking she needed.
"Oh... My... Fucking... God... Jack... Please... Cum!" she screamed in time with my powerful upward thrusts.
As if I had been waiting for her command, I felt my balls tighten, almost uncomfortably so, and the warm rush of cum start to push its way up my cock. This was going to be huge, far bigger than anything I'd given her before. Working instinctively for a split second, I threw her on her back, manoeuvred myself and her to the edge of the bed and pulled back hard on her thighs to rebury my cock inside her. The idea of her belly crushing me purely by the added weight and size of the cum I was about to fill her with was oddly not one I would have hated, but then I would have had to have stopped at some point. From here, we could go until I was done.
Intense isn't even a strong enough word to describe how cumming inside her felt that night. Every thrust of my hips must have unleashed a pint of cum at a time into her, and at the pace I was fucking her, that meant she was getting big fast. I've grown used to seeing her belly swell and inflate with my cum, but it felt like everything we'd done before this point was just the practice mode, something to ease us in before the real main event started.
Each thrust added another few inches to her stomach, her skin already stretched tight and moving quickly from bowling ball to medicine ball in size and beyond. The noises she was making were incredible, some euphoric mid point between pleasure and sexual desire. She grasped the sides of her stomach and I watched as her hands were prised further and further apart.
"Yes! Make me big, make me bigger than you ever have before!" she squealed.
Thank god that was what she wanted because I was nowhere near done. I should have felt exhausted by now, but the compulsion to just keep thrusting in and out of her and just keep unloading and unloading more and more wads of cum inside her was all encompassing. Her stomach was rising high above my own, inching up my chest but also spilling out either side of her. I had to release her thighs as the pressure built up by her rapidly expanding stomach was too much.
Mercifully, if I'm being honest, I felt the deluge start to dissipate. I was close to not being able to see her face and head, struggling to see her breasts and shoulders already. I pulled out of her once I was done and watched in slight awe as my cum started to leak out of her in a constant stream. It wasn't something I'd really noticed or paid much attention to before, but I think the sheer mass and weight of it all was forcing some of it back out. Phoebe either didn't care or wasn't aware enough to know it was happening.
"Are you ok?" I asked her.
"Mmph... so big... full..." she blathered.
She'd clearly had enough. I had literally fucked her senseless. That left me with a problem however. My cock was still hard. My balls were still swollen. It felt like I hadn't cum at all, like I was back to how I'd been when we started. I could feasibly have just started fucking Phoebe again and she likely wouldn't have minded (she'd have insisted if anything) but she was clearly in no fit state to say 'yes' or 'no' right now. Even as horny as I was, I knew it would have bothered me to take advantage of her like that, so a different solution was required.
Thank god we were alone in the house as I had to awkwardly walk to the bathroom, trying my best not to hit my cock off of anything. Once there I set to work trying to bring myself off, aiming as best I could at the bathtub. It took a while but once I started it was constant and unending. I was cumming so quickly and producing so much with each blast that despite the fact the plug was out, the tub started to fill. In the end, it almost got to above halfway full before I finally finished. The idea that all of that, or something close to it, was inside Phoebe right now was mind boggling.
Thankfully my cock and balls began to return to normal after that. I returned to the bedroom to find Phoebe had fallen asleep, likely out of exhaustion. A pool of my cum was forming between her legs and starting to seep off the edge of the bed. I spent much of the rest of the night making sure it didn't make too much of a mess.

This is where things take a bit of a turn. Usually it takes no more than a couple of days for Phoebe to return to normal size. This time though it took at least twice as long. Her contraceptives were designed to last for a few days, which had always been enough for us, but after the third day had passed and she still had quite the sizable cum bump, we both became concerned. There wasn't a way we knew of to quicken the process as any attempt I made to massage her stomach just made her feel stupidly horny again. So, she should just have taken more of the contraceptive right? Well by some error of fate, we had no more in the house and we wouldn't be able to get more for a few days...
We thought nothing of it for a little while, but decided to keep our sex 'normal' for a few weeks. Maybe we had some sixth sense about it or something. But when a month passed and Phoebe didn't get her period, we both suddenly understood that the shit had hit the fan. She did about a dozen tests in the end and they all said the same thing:
PREGNANT
We were both shocked. The reality of our situation hit us hard. What were we to do? Did we want a kid? Could we deal with one even? Her lifestyle and her job made kids a no go, at least for the time being, and even if it didn't, our lives and the time we were spending together would change immeasurably. There would be no more sex whenever we felt like it. No more inviting people to join us (even though we'd only done that once so far). Plus she'd have to postpone any appearances or shows she had booked.
