Maki Nishikino was a smart, reasonable woman. Right now, she was certain of a few things:

One, she was in a loving, dedicated relationship with her girlfriend, Nico Yazawa.

Two, she would never think of cheating on Nico in most circumstances.

Three, this set of circumstances was far from normal.

Four, it should have been impossible for anyone to possess a two-foot cock.

Five, that two-foot cock should have no business fitting inside her, even halfway.

Six, should it fit inside her, she should not enjoy it.

And seven, her relationship with Nico was in serious jeopardy.

Right now, as two entire feet of cock pistoned in and out of her abused pussy from behind, she couldn’t think about the events that led up to this point. All she could think about was how absolutely wrecked her body was, and how she would never, ever be able to return to a normal life after experiencing this.

Her womb was being fucked. The very idea of forming that sentence was so outlandish that she had to run it through her mind once more.

Her womb was being fucked. Her cervix, the last line of defense from the terrifying meatpole inside of her, had been battered down long ago. Her insides screamed in pain, a small part of her mind begging her to stop, but deep down she knew she never wanted to.

The person behind her, the one responsible for putting Maki in this cock-hungry state, was just as lust-addled as she. Her tongue lolled out of her mouth, her face twisted in unbridled pleasure. Her short hair bounced as she fucked Maki relentlessly. Her nails dug into Maki’s pillowy, supple ass, which allowed her much more give than she needed.

“Maki-chan!” Rin Hoshizora called Maki’s name repeatedly. She seemed unable to say much else beyond that, as she was preoccupied with shoving her twenty-four inch cock in and out of Maki’s womb. Every time, Maki wasn’t sure if it was able to go all the way in, but every time, Rin tugged it violently out of the vicegrip of her cervix, only to shove in back into her womb just moments later. And every time, Maki was capable of forming one singular thought.

Fuck. Fuck. Fuck. Fuck.

Yes, Rin, her former classmate, idol, and current close friend, was the one who was using her like a giant cocksleeve. Rin was the one who somehow hid a two-foot cock between her legs. And Rin was the one who Maki would gladly give everything for, if it meant feeling that stupidly large, thick cock slamming into her. Never mind the fact that she was living with Nico. Or the fact that Rin was living with Hanayo. None of that mattered, if they could stay connected like this.

Suddenly, the door to the bathroom they were in swung open, making Rin stop dead in her tracks. Unfortunately for Maki, she stopped fully hilted inside her, the thick, intrusive head of her cock jammed inside her womb. She bit down hard on her lip to stifle any desperate moans.

“Maki-chan, darling~” Nico sang into the room. Both Rin and Maki could see her silhouette from the other side of the curtain. “What would you like for dinner.”

“A-ah~” Maki stammered, unable to keep out the hitch of pleasure in her voice. “I-I, uh… Mmh!” She cried out as Rin began to move again. Her movements weren’t strong enough to pull her cock out of Maki’s womb, but she settled instead for fucking Maki slowly, deliberately.

Did she jam her toe? And what’s that smell? Nico wondered, noting the musty odor that permeated the bathroom. “Are you alright, Maki-chan?”

“Y-yes!” Maki answered with a quivering voice. “Eggs… and sausage would be nice…” she trailed off incoherently, feeling every last inch of Rin’s dick inside of her. “A big sausage…”

Nico stood in the door for a second longer before leaving without a word, closing the door behind her. Immediately, Rin resumed her breakneck pack, filling Maki up with ridiculous amounts of dick with every single thrust.

Fuck me, Maki thought as her insides were rearranged by Rin’s monster cock. If Rin kept up her pace, we would have been caught…

“Maki-chan’s pussy is the best!” Rin sighed. Hanayo had never let her put in more than ten inches of her dick inside, for fear of it ruining her body beyond repair. But Maki’s body was so lewd - her massive tits swung uncontrollably with each thrust, not to mention her bottomless pussy and the availability of even her womb to be ravaged -  that Rin couldn’t imagine a more perfect cocksleeve for her unbelievably massive cock. With each thrust, her hefty balls, the size of grapefruits, slapped against Maki’s ass. Inside churned her impending orgasm, and given how she battered Maki’s womb with each thrust, she had every intention of emptying every single drop of cum inside of Maki. With how suddenly her orgasm flared up and spread along every inch of her cock, it was about to happen.

“Maki-chan! I’m cumming!” Though Rin announced her orgasm with little warning, Maki felt it more than she heard it. She felt Rin’s pillar of cock ram the back of her womb. She felt her stomach bulging out, the skin stretching against the monster cock inside her. She felt each and every shot of cum hit the walls of her uterus, and Rin came so frequently and with such force that it began to pool in her womb quickly. She even felt the powerful pulses of Rin’s cock, running up against the walls of her stretched-out pussy. 

Before long, her womb began to stretch around the incredible output of cum inside, and despite this, Rin came again and again inside her. It should have been impossible, but with every spurt, her womb ballooned out even more, her stomach bulging around the expanse of her uterus further and further. Eventually, the top of her distended stomach began to push against the underside of her massive breasts, and she groaned in discomfort and pain, feeling the weight of liters of cum inside of her. Still, Rin didn’t pull out or even move an inch, seemingly intent on spending the entirety of her insanely long orgasm inside of Maki.

Maki’s eyes rolled back into her head. The pain, discomfort, and pleasure she got out of being overfilled with liters of cum was too much. She’d never, ever get this with Nico. Rin’s behemoth of a cock could provide her with everything she wanted: an insanely large dick and inhuman amounts of cum. Her stomach looked heavily pregnant with child, the apex of it now an angry red with the pressure it was dealing with from underneath. She was at her absolute limit.

Finally, after minutes of blowing her ridiculous load inside Maki, Rin was spent. After a few weak tugs, Maki’s cervix loosened its grip on her monster cock, and she pulled it out. Though a small flood of cum accompanied it, spilling into the bathtub, it was nothing compared to the majority which remained inside Maki. Rin’s cum was so thick, so viscous, that Maki’s womb would surely stay ballooned for hours to come. Rin sighed, feeling the last vestiges of Maki’s pussy clinging to her huge dick. Once she pulled it free, it swung around, reaching all the way up her torso with a thickness to match. It was a miracle she had even fit it inside of Maki, and her labia was proof of that; her pussy was spread so far apart that Rin could probably fit her whole arm inside. Even now that it was empty, it still gaped, having not forgotten the imprint of Rin’s two-foot cock.

Maki collapsed right away with nothing left to hold her up, falling to her knees inside the bathtub. Her swollen stomach pressed against the porcelain, bulging out far past her sides and keeping her upright. Her mind was completely broken, fixated solely on the two-foot cock that had just ruined her insides and the liters of cum that refused to leave her ballooned womb. She had no idea when it would shrink back down to its normal size, nor did she care.

She couldn’t wait to do this again.

“Maki-chan…” Rin whined, her back sliding down the side of the shower until she came to rest in a small pool of her own cum. “Your pussy is the best…”

Maki nodded weakly. The overpowering warmth inside her distended stomach occupied her thoughts, especially with how her stomach pressed against the cold porcelain of the bath. For now, she could only hope that she and Rin would be able to lie here, in post-coital bliss, until she could muster the strength to stand even despite her insanely cum-inflated stomach.

Suddenly, the door to the bathroom flew open once again. “Dinner’s ready -” Nico’s sing-song statement stopped in its tracks as the overwhelming musk hit her nostrils. Her jaw dropped to the floor as she took in the sight before her. Maki, her lover and longtime girlfriend, lay slumped over in the bathroom. Her stomach was ballooned to absurd proportions, to the point that she looked pregnant with triplets or perhaps even more. Her gaping pussy, stretched out to the width of her own fist, was emptying itself of thick, viscous seed at an agonizingly slow rate. And with her in the bathtub lay Rin, who possessed a massive cock. Even now, as it drooped slightly in post-coital bliss, it reached all the way past her modest breasts up to her neck. It was fucking huge.

Nico couldn’t feel betrayal, anger, or confusion in this point. She was simply dumbfounded, locked in place. But once Rin’s eyes came to rest on her petite figure, her cock stiffened to full mast. It was thicker than her own leg, and had a length to match. When she stood up and clambered over the edge of the bathtub, her cock cast a shadow over Nico, who watched, agape.

“Nico-chan, nya…” Rin’s eyes gleamed. Unbeknownst to Nico, an undeniable arousal pooled between her legs, staining her underwear. She couldn’t even imagine what would come next, or maybe it simply wasn’t possible to.

Maki stared at her own girlfriend and Rin from her spot in the bathtub. With the overbearing warmth of Rin’s cum pooling inside her bloated stomach, she could only close her eyes, powerless to stop what would happen next.
