I imagine it starts with being too horny for your own good. You spotted a cheap dildo at a thrift store and thought, why not? What's the worst that could happen? You were horny and had been pent up for weeks at this point. The fake cock would serve you nicely.
It's shape fascinated you. A long, thick cock of a bluish shade. One of those novelty alien dildos that looks impractical to use without prep work. But you were determined. You had the weekend alone with plenty of lube.
It was in your bedroom where you got to appreciate the strangeness of the toy. The shaft was textured in many small ridges and a seemingly porous skin. You swore you could see the minuscule skin-like detail you'd see on the real thing. Or as real as purple alien dildo could be. The warmth was just as off putting, as if it was straight off the factory floor.
But the balls. Those were the strangest part.
Heavy balls that hung a good two inches away from the shaft when held. The things were weighted with, what you could only assume, were glass bead with how heavy they were. The lumpy, squishy texture was all you could go off of. They were impracticably big, a solid fists worth at least.
With no suction cup to be seen, you assumed the weight of the balls must be intended to keep the shaft upright during intercourse. Definitely an odd design choice.
Maybe that's why it was given away.
Using an overly cautious amount of lube, you positioned the shaft beneath your hole and pressed it inside. Of course, you had prepped prior to this. That didn't mean you were ready to jam it in. Yet.
You cocked your head in a groan as it slowly eased inside. It felt amazing finally stretching around something thicker an your fingers. Your thighs trembled to fight against the urge to roughly fuck yourself too soon. But the too gentle nudge against your prostate was making it a losing battle.
Like you thought, the dildo's balls kept it upright as you pushed yourself up and down the shaft. It didn't take you long to start picking up the pace. It was far easier to get into a comfortable rhythm than you thought. Almost like it was made for you.
In fact, you forgot it was a fake cock at all. The warm material helped you to envision some unknown monster you below you, meeting your hips in time with yours. If you weren't so focused on your own pleasure, you swore you could feel it throb as you whined and thrust your hips faster. A feral heat coiled within your groin, demanding you keep gong despite the burning in your thighs. You're so close.
You didn't even have to angle yourself. This perfect cock hits you on that magic spot with every thrust of your hips. You eyes flutter and your cock twitches. You don't care if your neighbors hear you. Whoever designed this thing must be a godsend.
All at once, an orgasm crashes over you. You didn't even realize you were so close. Cum arcs from your dick with each throb of pleasure. You try to ignore the thoughts of laundry later and grind back into the wonderful cock, but the sudden wet heat at your thighs draws your attention.
You look down to find a spillage of thick cum – No, its the gel that was used to fill the dildo's balls. You instantly get up and hastily try to clean up as much of the mess as possible. Stupid, cheap, thrift store dildo. No wonder it was given away. The balls tore open after one use.
Or. That was your assumption
As you washed the thick, lumpy, gel from the toy, you couldn't find any tear or hole the stuff could've originated from. It had to have come from the balls though. You only knew that because of how deflated they were. No longer bulging from their gel filling, they now sagged pitifully.
You tsked, frustrated with how your nights been ruined. The awaiting laundry load and all too short masturbation session were one thing, but the pressing heat within you since it ended was another. You hole clenched around nothing and you sadly wished you had something to fill yourself with.
You sigh. You'll just have to put up with fingers again until you can afford a new toy. You put the dildo in a cabinet in your bathroom. Pettily refusing to use it as if it's some kind of punishment for ruining your night.
You proceed with cleaning up and carrying on like nothing happened. Just another toy that wasn't what you had hoped for. Despite sadly being stuck your hand to play with, you forget about the thing as the weeks follow.
You forget about how little of a mess there was to clean up compared to how much "gel" was inside its balls. You forget its lifelike texture and heat within your hand. You almost forget about it entirely. Until you start to swell.
You thought it was just bloating at first. You had been overly hungry for a while now. So much so, your friends commented on it. You didn't notice at first. You were far too busy. And horny. So fucking horny. You'd taken to letting people fuck on the side and even got some money out of it. It was enough to abate that intense need to be filled since that night with the dildo, but you could tell you were going to need more soon enough.
As your tummy swelled more, you were in denial of what was happening to you. When you hit the point your shirts couldn't hide your belly, normal human cocks weren't satisfying anymore. You had enough money to afford all the toys to your hearts desire, so it wasn't that big of a deal. But, as your belly continued to grow and you started needing actual effort to stand up, the toys stopped being enough as well. You couldn't orgasm.
As much as you wanted. As much you desperately humped and fucked whatever toy and cock you could get your hands on, you couldn't release. Worse of all, you finally had to confront the fact that you were indeed pregnant. How the hell did that happen? It shouldn't be scientifically possible.
You found yourself rubbing soothing hands against your aching belly on night, ignoring the throbbing want from your hole, and gently pressed down. You could feel it then. Bumps. Not a flat surface. Eggs. It clicked then. The dildo you had purchased months prior had impregnated you with its seed.
You rushed to the cabinet where you had discarded the thing, barely a run and more of a waddle at this point, and gasped at what you saw. The depleted balls that you had checked twice over were now bulging thicker than they had been before. You picked up the dildo in shaky hands and felt how unnaturally warm it was. It was pulsating with life, almost as if it knew how close you were to popping and it could relieve itself once more.
You liked your lips. You already knew what you were going to do.
You didn't get on the bed this time. You put it on the floor of the shower and fucked yourself on the alien cock with reckless abandon. Painful pleasure resounded through your pregnant belly with each thrust. You were delirious with arousal. You couldn't stop yourself even if you want to.
You felt a sudden pop within your core and a rush of liquid at your thighs. The satisfied groan of realization you were about to give birth was nothing to compare. You didn't stop fucking yourself then either, forcing the eggs that tumbled down back inside. The feeling was beyond explanation.
It was only when your body tired that you popped off the immaculate cock and let your birth occur. Your hole was so loose at this point you didn't even have to push the eggs for them to plop out. The contractions came and went, the eggs pressing against your prostate with each lay. You don't know how many times you came before you passed out.
You awoke in a puddle of your own cum and of the alien cock. It's ball were once more depleted, though you're unsure if any of it actually is inside of your body. Though that wont stop you from fucking yourself with it every chance you can get.
The pile of eggs next to, on closer inspection, house tiny cocks similar to that of the one you've been using. A smile creeps up on your face as you concoct the perfect business opportunity of your life.
