I would volunteer for a pregnancy like this

guy with a size kink gets knocked up by a size shifter. all through his pregnancy, his baby has growth and shrinking spurts the way other babies would kick. it's disorienting and painful. one minute he'll be fine, then his baby will knock him on his ass by deciding to grow as big as a foal, then his bump disappears when the baby shrinks to the size of a peanut. he has no predictability for any of this, and it's made his pregnancy a confusing nightmare. he didn't know this would happen, the dad didn't warn him, and he had to furiously look up sizeshifter pregnancy after an embarrassing growth spurt in the grocery store his first trimester, when baby decided to make him look ready to pop and tore apart his favorite shirt. clothes have been out of the question for months now. his belly skin is so red and stretched out and agitated with the constant inflation and deflation, the baby just getting more active near the end of the pregnancy. he worries about the birth. what if his baby has a growth spurt that makes it impossible to push out? or godforbid, one while he's actively crowning?

Having the baby shift sizes while he's giving birth would be so good, it keeps growing and shrinking rapidly while he's trying to push it out, making his labor so much longer and more painful than normal.

It's constantly changing shape, stretching him wider than his body was ever meant to stretch and getting stuck when it shifts into something huge. He screams and cries, thrashing in pain as he bucks his hips wildly in an attempt to dislodge the massive head, trembling under his towering belly and begging his baby to shrink before it breaks him. When it finally does shrink, he pushes frantically, not even waiting for contractions because he desperately needs to make as much progress as he can while the baby is small enough to be pushed out.

His labor drags on for hours, constantly bouncing back between non stop pushing when it's small and feeling like its about to split him in half and getting stuck when it's too big. He never knows how long each phase will be, he could have only minutes to push and hours of torture stretching around a creature with the head the size of a watermelon, or vice versa. His labor could last days if the baby decides to shift too big too much, leaving him exhausted and barely conscious by the time he manages to get it out.

He feels it slip out with one last push and collapses back in relief, thinking he's finally done, but suddenly his tummy jumps up, swelling right back up until he's even bigger than he started. He screams in pain, watching his belly in horror as it squirms and bounces with movement. It turns out that because shape shifting babies are always changing and shifting sizes, it's nearly impossible to figure out how many there really are. What he though was one baby constantly shrinking and growing could have actually been twins, triplets, or more.

After hours and hours of giving birth to just one baby, he realizes he has to do it all over again, and without knowing how many babies he's actually carrying, he may have to push out many more after that...

Like Girls Do [Chapter 1]

Kyle may be an alpha gym bro Chad, but he harbors a dark secret: he loves pregnant bellies and wants to have one of his own. Inspired by a very pregnant streamer and after a clandestine encounter while his girlfriend is out of town, Kyle may very well get what he wants.

Contains: male pregnancy (mpreg), belly expansion, light feedism, weight gain, humiliation, breast growth, lactation, m/m, m/f

Kyle’s hips bucked, his thrusting as steady and rhythmic as a well-oiled machine. His fist clenched around the thick tangle of his girlfriend’s hair, the strands pulled into a long ponytail from her scalp to his closed grasp. She squealed and chirped with each powerful thrust, her eyes wide and her cheek shifting forward and back on the mattress as she endured the thickness spreading her repeatedly from behind.

His palm collided with her ass check, a sharp crack snapping through the room.

“Tell me you want it,” he commanded, his voice thick and rough with his impending orgasm.

Katie mewled, her dainty fingers curling on the bed sheets, her eyes practically rolling as the meaty tip of her boyfriend’s cock pounded against the puckered ring of her cervix.

“Give it to me, Daddy!” she moaned obediently. “This pussy is all yours!”

The sound of it was enough to make Kyle’s balls tighten. His cock swelled, his rod full to bursting, precum spurting against Katie’s inner walls like a pipe about to blow.

“Gonna cum,” he grunted, the speed of his thrusts doubling, the grip on her hair tightening, his girlfriend’s head jerking back below him.

Kyle rode through his orgasm, his load filling the woman beneath him, coating his cock and gushing out of the stretched slit of her pussy. Katie wailed, the noise whining and whorish, her internal muscles squeezing and releasing into a milking motion around him, her body guzzling down the alpha seed he was dumping into her.

As he pleasure descended, his pumping slowed, his hips rocking long and deep, his deep voice groaning out a low “Yeah...yeah…” in an almost victorious rhythm.

Katie did her part, maintaining the dramatic arch of her back even through the prolonged finish until her man finally withdrew from her, a thick spurt of creamy spunk seeping out of her hole.

She purred, her voice drippy with lust, “Oooh, good job, baby, you really fucked my little pussy up.”

He gave her ass another little light smack, his cock still huge and long between his legs, the member gleaming with both of their fluids. Katie responded with a playful wriggle of her hips.

“Sure did,” he replied, taking a towel from the nightstand and cleaning himself off. “Did you cum?”

His girlfriend was already out of position and running a brush through her long blonde hair. She took a black scrunchie from the top of her dresser pulled her mane through it, watching herself in the mirror of her vanity.

“No,” she answered. “But it’s whatever. You know I love to get you off, baby.”

Kyle enjoyed his post-orgasm glow as he watched her pull on a powder blue tank top and step into a pair of black spandex shorts. Her movements were quick and clean and lean, just like her.

“Headed to the gym?” he asked.

“You know it. It’s leg day.”

The comment drew his attention to her lower body. Katie’s legs were slender but strong, shaven, and glowing. Their gym had a tanning salon complimentary with their membership and Katie had been making great use of it-- for $100 a month she was going to get her money’s worth.

Stepping into her tennis shoes, the blonde turned and checked out her ass in the full-length mirror beside their closet. Kyle got a good look, too. Her cheeks were thick and juicy, a testament to her years of hard work. It was pointless to lie and say that he first noticed her for her personality. He was on the treadmill and she was on the squat rack directly in front of him, her fat cheeks bobbing up and down in a private show. He had practically bust out of his shorts then and there.

That was 3 years ago. Now he just bust in her, whenever he wanted. They both liked it that way. Katie would never have submitted to a guy weaker than him. Physically, he was commanding, and just as importantly he walked the walk. He actually had the ability to put Katie in her place. No other man had been able to do that. She liked the discipline, and he did too.

“Alright, babe,” he said, slinging her pink gym bag over her shoulder. She pranced over to the bed and gave him a peck on the cheek. “See you in a bit. Love you.”

“Love you, too,” he answered, his hands clasped behind his reclined head, his muscular arms splayed out beside him.

Kyle listened to the dull sounds of her footsteps on the hardwood floor of the kitchen, the jingle of her keys, then the slam and lock of the door. He waited a few moments, listening for the potential sound of her returning for a forgotten item, then grabbed his phone off the beside table.

The man’s prick had only softened partway and began to perk up again, Pavlovian, as he opened his internet browser. He clicked into his hidden setting and typed in a familiar URL, his free hand already fondling his re-hardening erection. The web page opened and before his eyes flashes the images he’d been hungering for.

Bellies. Big ones.

Kyle’s large hand slid around his tip, his member still sticky with his and his girlfriend’s drying fluids. Blood was rushing into his cock already at the sight of the engorged and distended middles on the screen.

The heavy, pregnant bellies on the women were mostly real, with only a few of them being retouched to appear a bit larger, but the one’s on the men were, of course, all fake. He scrolled a bit, perusing the digital menu for a satisfactory model, passing by a brunette woman caressing a stretched mound holding nearly full-term twins, a twinkish guy with a ‘first trimester’ bulge, and a woman supposedly carrying triplets. Her breasts were painfully engorged, blue veins crawling from her nipples across the flushed expanse of her tits. Her belly was scarred with stretch marks, her womb jutting out so far from her abdomen that her skin visibly strained to contain it. He could believe that there were three in there. His hand moved on his cock, his tip already seeping again as he imagined the feeling of having his abdomen so heavy, full, and tight with babies.

That was really the key. It wasn’t enough to impregnate-- Kyle wanted to be pregnant.

He was a big guy, and strong. Very strong. He could have carried a big pregnancy, if it had been possible. As he looked at the pregnant models, he imagined his muscular, defined core melting away into a rounded, bulging middle, the weight of the child (or children) inside him forcing his gut outward, the size of them making their movements visible through his flesh, feet and heads pushing out of him as he struggled to waddle even short distanced.

The motion of his hand picked up, his testicles high and tight against his body.

He scrolled down the dashboard of images, coming across a strong masculine guy, almost like himself, cradling the underside of a cumbersome womb. It was definitely photoshopped, but he didn’t care. The man’s belly was tight, his navel stretched into a thin vertical slit on the far end of his mound, the natural hair of his abdomen spread thin across the surface of his skin from how far his gut had expanded. The man’s chest was engorged, his dark nipples thickened, milk rushing into the usually flat plane of flesh as his body prepared to feed the large child inside him.

Bigger and bigger. Fuck the gym. Fuck his diet. Kyle imagined himself lying reclined on his bed, rubbing both hands over his huge, hard belly as kicks ravaged him from the inside, his belly button jutting outward as a foot distended him from within.

Cream spurted from the end of his cock, splattering over his fingers. His eyes crossed, his mouth pulled compulsively into a tight O, his moan long and lewd and nothing like the hyper-masculine performance he had just put on for his girlfriend minutes before.

“Get me pregnant, impregnate me,” he whined, pumping himself frantically as he jerked his hips through his orgasm. “I wanna feel the baby, I wanna be big!”

It didn’t matter that he’d only just cum, his load was huge. It always was when he was looking at his favorite material. Normal sex was great, but nothing pushed his buttons like imagining himself swollen and struggling with a fat, baby-filled belly.

As he began to downward descent of his pleasure, Kyle’s stroking slowed. His entire lap was covered in cum, his fist sticky with it, even a few fat, rogue drops sticking to his chest hair. A few final twangs of pleasure plucked through his cock before he was immediately blanketed in shameful urgency, cleaning himself up and clearing his browser history, then double checking just to be sure. There was no way anyone could know about this, especially not his female apex predator of a girlfriend.

After two consecutive orgasms Kyle was juiced up. He felt a rush from his head to his toes. Post-nut shame lurked menacingly in his gut like a huge ugly spider but he shoved it down, looked away from it, and went to the gym instead.

Katie had already hit a steady pace on the treadmill, her favorite warm up, when he got there. As much as he’d steered her in the right direction with lifting she would always be a cardio bunny and Pilates princess at heart. He hopped on the machine next to her and gave a short wave to get her attention. The blonde pulled her Air Pods from her ears but didn’t stop jogging.

“Come to spy on me, Coach?” she asked, her voice barely indicating her effort in spite of her pace.

Kyle pressed the upwards arrow on the machine a few times and began a steady walk forward.

“Thought I’d get another pump on,” he answered, shooting her a flirty wink. His girlfriend smiled despite herself.

“Works out anyway,” she said, “I forgot to tell you earlier, but I have to go Chicago this weekend.”

“Eh? What for?”

There was a sheen of sweat over his girlfriend’s face and arms, making her bronzed skin gleam like the flawless plastic of a Barbie doll. Her body had not a single ounce of extra fat on it, the whole thing tight and trim and firm without a lump or bump to jiggle as she ran. She turned the speed of the treadmill up a few points.

She said, “My sister has this stupid thing she needs me to go to and I owe her one. I leave Friday after work but I’ll be home Sunday morning. I’m not staying any longer than I have to.”

Kyle bumped his speed up so that he was at a slow jog, the rotating belt humming mechanically underneath him. The weight of his body thumped heavily with each step.

“Sucks for you,” he said.

She scoffed, “Tell me about it.”

The man on the screen circled his palms around his distended belly-- his womb. Kyle watched the motion, hypnotized. Periodically, small indents and bulges appeared on the surface of his skin, little limbs pushing out and making the man exhale softly from the sensation.

These edits are getting really real looking, he thought as he fondled himself below his desk.

There were a decent amount of other people in the stream, a few of them typing horny comments into the chat with a notification popping up with a congratulatory ding! whenever someone paid the guy a new tip.

“Thank you, donor,” the man purred, smiling as he rubbed and held his heavy mound.

Kyle had only ever looked at pictures of his fetish before, he’d never seen a stream of it. He wondered how the man was faking his pregnancy, it looked so real, especially with all the kicks and movement.

The man on camera was reclining on his side so that his stuffed gut jutted out in front of him, his deep belly button hanging down to the bottom corner of the screen. His belly jerked again, the mass shifting to the side, and the man moaned in a way that to Kyle was indiscernible from pain or pleasure.

“God, they’re really active tonight,” the model cooed, his hand drifting down from his navel to his prick, the presumably rigid member concealed by the size of his pendulous gut.

Kyle’s own cock was throbbing, as hard as stone and leaking into his underwear. He smeared the viscous fluid over the slit with his thumb before giving the length a long, slow stroke. His hips bucked compulsively and a moan brewed warmly behind his lips as the man’s belly trembled with movement again.

With his free hand he typed, How many are in there?

With a smile, the model answered aloud, “Twins. I got knocked up really good.”

The speed of his hand increased at the thought of it. Two babies. Inside him. Moving and kicking around, squirming against each other. And he’d be so big. His belly would run out of room and become lopsided with how they were crammed inside him.

Pre-cum spurted onto his hand, thick and sticky and swirled with white. It must have been so hard to move with all that baby inside him. Kyle loved the idea of being weighed down with baby, immobilized by it, his great strength overcome by the weight of his own body.

Are u really pregnant? he typed into the chat box, too horny to even feel silly asking.

The model cupped under his mound, lifting the baby-filled mass, his fingertips sinking in to the plush cushion of fat that coated his distended womb.

He laughed, his smile blaring white on the dim, low-resolution image of the webcam.

“Very pregnant, Anon,” he said.

Are u trans? Kyle’s genuine curiosity and his arousal were unifying now, twin currents of energy swirling around each other and tangling like wrestling snakes.

The guy laughed again, the sound surprisingly earnest.

“No, I’m not trans,” he said. “Just very, very lucky.”

Whether this guy was role playing or just straight up delusional Kyle didn’t know, and he didn’t have the brainpower to figure it out. The man on the screen clutched his huge belly with both hands, jiggling it, his head tilting back as he moaned into the air.

“So fucking big,” he mewled. “And they just keep getting bigger. These babies are stretching me out!”

The twins churned visibly inside him, their limbs forming irregular shifting protrusions on his strained gut, his flesh warping. Kyle’s prick throbbed in his hand, pulsing hard against his grasp, pleasure spearing through his slit as his approaching orgasm clenched rapidly in his pelvis.

A bulge appeared below the man’s navel, jutting out so far that Kyle could make out the distinct imprints of the baby’s foot, its toes, the skin tenting, and with a grunt of surprise and ecstasy he came.

Before the last drop was even out of his body, Kyle had slammed his laptop shut and was panting in the dark.
