Swim Time [Man to Pregnant Woman TG]

Free Request for Nathan Durham

After being rude about a pregnant water aerobics class taking up his precious swim time, man finds himself transforming into a pregnant swim instructor.

I stepped into the humidity and breathed deeply. The smell of chlorine and water seeped into me, and I smiled; finally. It had been a week since the pool was closed for cleaning, and it felt like an eternity. I’d been counting down the days, eagerly anticipating the moment I could dive back into the water and feel the cool embrace of the pool against my burning muscles as I swam lap after lap, pushing myself further with every stroke. The break had been long enough. I had a training routine to get back to, and I was ready to hit it hard.

I had come prepared. I’d eaten a light, carb heavy breakfast and was ready to burn it all off. Today was going to be a good day. I could already feel the water gliding around me, the rhythm of my strokes, my heart pumping in time with the movement. The ladies giggled as I got out of the pool with water, making my smooth chest glisten. 

With a grin on my face, I walked past the kid's section and into the lap pool, ready to chuck my bag on the nearest bench and dive right in. But then I saw it: a group of women standing in the shallows, laughing and chatting, all dressed in swimsuits and holding colourful foam dumbbells. Even with the water warping their bodies, I could tell that most were pregnant. I frowned. Something wasn’t right. I spotted one of the pool attendants standing by, looking over their clipboard, and approached. 

“Good morning! How can I help you?” The woman smiled. 

“I’m here to swim laps,” I said, trying to hide the irritation in my voice. “Is the lap pool open? The lines aren't in the water.”

“Oh, yes,” she said, nodding enthusiastically. “But just so you know, we have a water aerobics class in session right now. It’s for pregnant women, so it’s a little... crowded in there.”

I blinked, struggling to comprehend. 

“Pregnant women?” I repeated. “You’re telling me I can’t swim laps because they’re having a class in there?”

The attendant’s smile faltered, but she nodded. 

“Yes, I’m afraid so. They’ve got the pool reserved for the next hour.”

I stood there, stunned. An hour? They had the whole lap pool for an hour, and I had to wait? I’d been waiting all week for this moment, and now I was going to lose the whole morning to some aqua fitness class?

“Since when do you hold aerobics in the lap pool? What sort of backwards logic is that?”

“It’s the only pool big enough, we used to hold the class in the afternoons but since it was clean we decided to reshuffle our events.”

“But I work in the afternoon!”

I only had a few free hours a day, all the mornings, losing an hour out of my time was huge. I’d barely get to train at all before I had to hop out to go and get ready for my shift. 

“Look, this is ridiculous,” I said, voice rising. “I’ve been coming here for years. I plan my day around the pool schedule. I can’t just sit around and wait for these women to finish their class.”

The attendant’s smile faltered again, but she remained calm. 

“I understand your frustration, sir. But it’s a scheduled class, and we can’t just cancel it.”

I was boiling now. 

“You can’t just cancel it? This is a lap pool! This is supposed to be for serious swimmers, not whatever that is!” I gestured toward the water aerobics class.

“I’m sorry, sir,” she said, not backing down and not sounding sorry at all. “But you’ll have to wait your turn.”

My hands were clenched into fists. I couldn’t believe I was having this conversation. This was my time—my time to train, to swim, to be at peace in the water. And now it was being wasted.

“I’m going to talk to the manager,” I said, turning on my heel again.

The attendant didn’t try to stop me as I marched toward the office. I could feel my blood pressure rising with every step. I pushed the door open and found the manager behind the desk, her face lighting up as she saw me. Idiot. She didn’t know what was coming.

“Excuse me,” I said, trying to keep my voice steady, but failing. “I need to speak with you. I’ve been coming here for a long time, and I just found out that the lap pool is closed for an hour because of a water aerobics class. This is completely unacceptable!”

The manager raised an eyebrow, leaning back in her chair. 

“I see. And what seems to be the problem?”

“What’s the problem? The problem is that I’ve been waiting for a week to get back in the pool, and now I have to wait an hour because of a class for pregnant women? It’s ridiculous! I need to swim laps. I have a training schedule, and you’re messing it up.”

She didn’t flinch. Instead, she sighed and pushed herself up from the chair. 

“Let me get this straight,” she said, her tone cold. “You’re upset because some women are using the pool for an hour? Because they’re pregnant? You do realize that they’re using the pool for their health, right?”

“That’s not the point,” I snapped. “I’m paying to use the pool, and it’s supposed to be for lap swimming. This is a joke!”

“Pregnant women are carrying a lot of weight, and it's impossible to do most exercises.” The manager snapped. “This class is a way for them to stay healthy and take some of that pain away from their backs. I will not cancel the class for the convenience of one man.”

I rolled my eyes. Utterly pathetic. I bet she’d change the whole pool schedule if I was a preggo who had to work in the afternoons. Without another word, I spun on my heels and headed out the door. I was going to swim, whether she liked it or not. There was a large open pool for free use, no lanes, so swimming laps would be an exercise in avoiding people, but at least I’d be in the water. 

I threw down my bag and stood at the edge of the pool, stretching my back and hearing it pop. That lady was going on about the back pain pregnant women get, but what about mine? My back was aching from hours sitting in that damn office chair. I bent my spine a few more times before stepping down the ladder into the pool. The water felt wonderful against my legs, I shaved for speed so they were totally smooth. Looking down, I couldn’t help but giggle; they almost looked shapley thanks to the distortion in the water. 

The cool chlorine hit my skin, and I started to swim, kicking hard against the water’s resistance, my strokes strong and steady. The rhythmic motion always helped to quiet my mind. It would have been perfect if I didn't have to swerve around the group of kids playing Marco Polo. Awkwardly, I made my way around them to the other side of the pool, expertly flipping over and pushing off. 

The movement usually felt smooth, second nature after years of practice but today, something felt off. A dull, nagging discomfort started in my lower back, like a muscle cramp. I tried to shake it off, but it didn’t go away. The feeling spread, almost like my body was betraying me, and as I turned to make another lap. This time I didn’t flip, I stopped and turned on the spot and found I was strangely winded already. I felt a strange weight in my chest as if the air around me had thickened.

“I must have gotten more out of shape than I thought…” I muttered. 

That didn’t make sense, though, I’d only gone a single week without my usual routine. There was no reason to feel like this. I was in peak condition, mid-thirties, athletic, strong. But then a pressure formed in my stomach, like something was stretching or growing inside of me. My breath quickened.

Could I have gotten food poisoning? No, I’d had that once before, it was probably just weird stomach rumbles. I was just tired and frustrated. I've been working too much lately. Yeah, that had to be it. The strange feelings weren't going away, though. It felt like something was making my skin stretch and swell as I moved through the water. 

My ass cheeks almost felt like they were growing, and there was a strange pressure between my legs. Almost like a hand was pressing against my cock, but not in a pleasurable way. Feeling off-kilter, I made my way to the ladder and started to climb, but that only made me more sure something was wrong. My ass felt heavy, so did my chest, and the moment the water wasn't supporting me, I felt gravity pulling down on my spine. 

“What the hell?”

I looked down, and my jaw dropped. My swim trunks were gone, I could still feel fabric cupping my crotch, but there was nothing around my legs. Not that I could see and confirm it, because my belly was in the way. My normally toned, muscular stomach was now round, like a beachball. The skin stretched smooth, and my belly button was forced out as well. 

“No way…”

I wasn’t just fat. I was pregnant! 

“But…But…”

How could that be? I was a guy! I looked around quickly before dropping back into the water. What if somebody saw me? I could feel that strange expanding feeling spreading to other parts of my body now. My chest mainly. I’d been so distracted by the roundness of my belly I hadn’t even noticed my growing tits. I cupped them underwater and let out a small squeak of shock. They were so soft and supple; I could feel them growing. Even though the bikini top I was now inexplicably wearing. 

But as I tried to continue swimming, what else could I do? I didn’t want to think about what was happening. My stomach felt heavier, and I instinctively placed a hand on it, feeling the firm, rounded shape beneath my fingers. My heart raced. I tried to push myself up, to lift myself out of the water—but my body felt sluggish like it didn’t quite obey me anymore.

The water around me seemed to ripple differently. I glanced at my reflection on the surface, eyes widening in disbelief. Even in the rippling water, I could see the changes; my hair pulled up in a limp ponytail, my full lips. 

“No,” I muttered, my voice cracking slightly. “This isn’t happening.”

I swam toward the pool’s edge, gripping the tiles and pulling myself out with trembling arms. Standing on shaky legs, I felt the weight of my new form. The sensation was overwhelming—my body shifting and stretching in ways I couldn’t control, my muscles tightening in strange ways as if they were preparing for something.

The heat in my chest intensified, spreading across my shoulders and arms—like my body was swelling in every possible direction. My clothes felt tight, and I reached down to tug at the waistband of my swim trunks, only to find they were now a tight pair of bikini briefs. Complete with ribbon ties at my hips. 

My cock was squashed, almost painfully by the tight fabric, and to my horror, I could feel it slowly being pushed back into my body. My balls seemed to meld with my skin, disappearing entirely and leaving something else in their place. There was a subtle warmth there that might have been pleasant if I wasn't so freaked out. 

With some difficulty, I finally hefted myself out of the water and groaned. My ankles protested each step as I made my way to the glass wall separating the open pool from my usual lap pool. As my reflection in the glass doors of the pool house became clearer, I saw what had to be impossible: a visible baby bump beneath my skin. My chest was now full, two heavy breasts hanging, my arms were rounder, my legs wider. The transformation wasn’t subtle—it was undeniable.

I stumbled back, nearly falling into the pool again. I glanced over at the women gathered around the shallows of the lap pool. I looked just like them now. 

“This can't be happening.”

And yet, there I was, standing by the edge of the pool with a pregnant belly and no explanation. I felt something inside me move, a swift kick to the side that had me gasping in shock. One of the women turned to regard me. She gave me a small, curious smile, a touch of sympathy that made me wince. 

“There you are!”

It was the same pool attendant from before, only all the anger in her voice was replaced with honey. 

“You must be the new aerobics teacher.” She smiled, handing me a pair of little foam dumbbells. “The class is waiting for you.”

“I…yes, of course.”

The words left my lips before I could stop them. It was like I was on autopilot, slowly climbing into the pool, one dumbbell awkwardly squashed under my arm so I could hold my belly. The second I was in the water, I sighed in relief. It took the weight of my belly away. I wanted to stay there and float, but instead, I found myself moving to the front of the group of women. Somebody hit the music, and a wide smile spread across my face. 

“Alright, ladies, let’s get moving! A healthy body means a healthy baby!”
 They all giggled, and so did I. The sound felt so strange in my chest. My body began to move on its own, jumping and turning slowly while lifting the dumbbells in time with the music. It was so embarrassing, but I couldn’t stop! I could feel my baby kicking inside, any day now, they would be born. I had no idea what had happened to me, but it seemed like I had no choice but to get used to it. Something told me this was going to be my life now.
