Muscle Mom to Be
Unexpectedly, Zoe gets pregnant. She really thought that her bodybuilding regimen would prevent this, but … it happened. Now Tyler and her have to figure this out.

And here’s a preview:

Zoe pushed her strong fingers into Tyler’s chest muscles. She grinned at her boyfriend from above and started gyrating her powerful hips against his cock. Tyler was very well-hung, and his dick responded quickly, rising against her hard six-pack. She chuckled:

“I love how quick you get hard …”

“It’s easy when you’re as hot as this …”

“Takes one to know one …”

His hands went to her waist. He felt her obliques shift under his fingers as she made him harder and harder. She looked down and saw his member poke up, brushing against the bottom of her tits. Then she lifted herself up on her strong legs, took his shlong carefully in her hands and directed it into her pussy.

“Mmmh … Yesss …”

He gasped as he entered her warm cave, sinking deeper and deeper into it. Zoe began massaging his rod with her inner muscles. She had amazing control over these due to years of yoga, and Tyler had to focus so as not to cum immediately.

“Fuck … This is going to be hard …”

“Oh, you are hard already …”

She slipped downwards, filling his cock spread her open. Now she began to move her midsection in long, intense waves, and Tyler’s expression got a bit derailed as she brought him closer and closer to cumming. Zoe’s expression was just as intense. She moaned loudly as his big dick hit the best spot.

“Yesss … So big …”

His hands dug into her butt, exploring the hard lines of her glutes. He felt as if she was milking him, her body tensing and relaxing around his rod. He knew he wouldn’t last long now. Zoe was impossible to resist. His hands slipped up her strong back and he pulled her close, kissed her deeply and whispered:

“I love you, Zoe … You’re my goddess …”

“Just you wait … I love you too … Mmmh …”

Tyler tensed up his butt and began answering her moves with slow, intense trusts. Zoe gasped, and then, he felt that she was starting to cum. The pressure inside her suddenly increased, and he shot his load, causing her to tighten herself harder, sucking him dry as she launched into a cascade of orgasms …

 

“Um … Tyler …”

The muscleman was busy preparing meals for the next week, the chicken breast sizzling in the pan.

“Yes, my love? What’s up? Anything worrying you?”

“Uh-huh. Tyler … I … I think I’m pregnant.”

“What? I thought … I thought you were on the pill?”

“No? I … I kinda assumed that I wouldn’t get pregnant on account of my training?”

“Oh. Well … That didn’t work out, right?” Now Tyler was also looking worried. “So what do we do now? Wanna keep it?”

“Of course! I mean … it’s gonna be our kid, right?”

“Fine by me. I think you’re going to be a great mom. Though it’s going to change everything, won’t it?”

Zoe grinned:

“Definitely. And I want you to be a great dad!”

“You know me, love. I never do anything half-assed!”

They embraced and kissed very quickly, because Tyler had to go back to the chicken breast.

 

Tyler looked nervously at his girlfriend. She was warming up on a mat, stretching herself into a very enticing pretzel. Fuck, that woman was so amazingly hot … Her long blond hair was tied into a big bun so it wouldn’t get in the way, and her freckles were giving her that cheeky style he loved about her. Okay, that wasn’t all he loved about her. She was just amazing on all fronts: almost a decade of bodybuilding had given her a hard, elegant physique, packed with surprisingly mature muscles for someone in her late twenties. She wasn’t too massive, but the intensity of her physique was incredible … Even in her bulking phase, there was a certain vascularity to her, and despite this, she still managed to have enough bodyfat to have a nice pair of breasts that were well-supported by her hard pecs.

If he weren’t worried right now, he would be drooling …

Zoe finished her first round of exercises by supporting herself on one hand only, her muscular body resting perfectly level on her well-trained forearm.

He asked:

“Are you really sure about that, Zoe? Do you think this is a good idea? Training all the way through your pregnancy? You know we can just skip the competition and do it when the kid’s there?”

“Yes, of course. I want to do this, and I want to win. The doctor said it was fine.”

“But it could be dangerous for the baby.”

“The doctor said I share the same genes with my grandmother, and she worked the family farm all through seven pregnancies and you know my six aunts and uncles, right?”

Tyler shuddered. He was a big guy, 6’1”, broad shoulders, having spent his childhood and teen years as a competitive wrestler and now into bodybuilding with his girlfriend. And yet, Zoe’s people were all quite huge. Not tall, just extremely powerful. He was both relieved and disappointed that she was so small in comparison, even if she was 5’8”.

“Okay … Just … promise me you’ll be careful.”

She pushed herself up and landed on her feet.

“Sure! I don’t want you to be worried.”

She cuddled against him and kissed him.

“You’re going to be a great dad, Tyler. And our kid is going to be amazing. Everything will be wonderful. Now, let’s hit the weights!”

He felt relieved and joined her.

 

The first trimester approached its end, and Zoe had stuck to it. The pregnancy was undeniable already. Her body had changed, but not in the way anybody expected. Her belly had expanded quite a bit, giving her a bit of a rounded shape in her midsection, but to the doctor’s surprise, her abs hadn’t split. Instead, they had changed structure and had adapted around the baby, supporting it from all sides while somehow leaving enough space for it to grow. And both the kid and the mother were growing well: In these three months, Zoe had somehow put on eight pounds of muscle, and her body was looking quite massive compared to when she started. Also, her breasts had gained at least a cup size. Her skin was glowing, and she felt so full of energy, Tyler was having trouble keeping up with her.

Right now, she was squatting 350 pounds, which was beyond her previous personal best, and she was closing in on Tyler’s level. It was absolutely fascinating, but also quite confusing. Where did that power come from?

She went down again, with a very nervous Tyler hovering behind her, ready to catch the bar should anything go wrong. From where he stood, he could see her incredibly muscular legs tighten and release, her rounded, brutally powerful ass coming close to him. She was amazing like this, and if Tyler wasn’t concentrating on keeping her safe, he would probably have exploded in horniness at that time.

Zoe went up now slowly, controlling her movement perfectly, the weight digging into her skin, but it didn’t seem to bother her much. As she reached the end of her set, Tyler helped her rack the bar. She stood up straight and stretched her back, letting her lats flare outwards. Her proportions had changed in an even more insane way. Her waist was as tight as ever, but her shoulders had grown, and she looked even more hourglassy than before.

He handed her a towel and she wiped off the sweat from her face and her bust, then kissed him.

“Thank you … Though … Do you think I should increase the load for the next set? I think this went really easy.”

“You think that’s a good idea?”

“Oh, I got you watching over me, Tyler. I’m not afraid. And it’s not bothering the kid, is it?”

“Okay. Then we’ll add ten pounds?”

“Make it twenty!”

 

That evening, Tyler gave his girlfriend a relaxing full body massage. It was different from the post-workout one, which invariably tended to be rather brutal. This one was soft and soothing, and Zoe enjoyed it a lot. She was lying naked on the bed, resting on her back as Tyler got busy on her feet, then her legs, then her arms …

She felt warm and glowing in his hands, feeling her well-used muscles calm down after a hard workout. Despite his size and strength, Tyler could be very gentle, and the way he pleased her made her purr.

“This is nice … How about using your tongue too?”

She carefully directed him towards her crotch. Tyler nodded and got between her thick, muscle-packed legs. It was leg day, and she had really pushed herself. Even now, after she had relaxed, her thighs were still all pumped. With a grin, he started licking her pussy, circling her clit, and exploring her folds.

Zoe moaned loudly as her husband licked and kissed her, getting her close to orgasm in a matter of moments. She lifted her legs up a bit and squeezed his head in her thighs. The muscular young man was unfazed, confident that his girlfriend wouldn’t crush him. As he brought her closer and closer to cumming, though, he began to feel a bit nervous. Pregnant Zoe seemed to be much less controlled than before.

“Mmmh … Tyler … I love your tongue …”

She came fast, soaking his face in her juices, and leaving him red and glowing, with some slight indentations on his face. Then, with a big grin, she returned the favor.

 

The second trimester was amazing for the both of them. Somehow, the pregnancy had kickstarted Zoe’s body, and she was growing like a weed. Sure, she was eating for two, as she said, and she was building two bodies at once, but Tyler started to find meal prep a bit exhausting. She was now eating seven meals a day, and all that protein seemed to go straight to her muscles.

As her body grew, she also intensified her workouts, moving weights she never had before, and always asking for more.

Right now, she was doing pullups and a rather nervous Tyler was hovering below her, ready to catch her should she lose her grip. The thing was though, he was in an excellent position to watch her muscles work, and he really loved the show …

Zoe was tensing her arms again, her muscular body getting pulled upwards with slow precision. He could see her biceps swell up dramatically. It had always been a great body part for her, but since the pregnancy, it had really blown up, now reaching close to eighteen inches around fully pumped. And it didn’t appear to slow down its growth … The young mother-to-be lifted her body up to the apex, her chin passing the bar easily. A thick vein was snaking over her arm as she held the position.

She grinned at Tyler from above. From where he was, he had a nice view of her expanded belly. The doctor had told them that the baby was developing nicely, growing a bit faster than expected, but still normal. This meant that Zoe now sported a big bump, nice and round, though curiously patterned with those abs that just stuck right there, bulging harder than ever before.

Her belly really looked a bit like a grenade, ready to blow Tyler’s mind to smithereens, and turning him on all the way to eleven. To be honest, Zoe’s boobs might play a role in that too. Ever since her belly had started to grow like this, her tits had followed suit, ballooning and becoming rounder and fuller with every day. If she hadn’t grown a set of extremely powerful pecs, they would have started to droop a bit, simply on account of how large they were, but those muscles held them aloft and perky. It was a joy to see them bounce and wobble when she walked, her hard muscular ass swinging at the same time …

Suffice to say that Tyler was rock-hard when Zoe lowered herself back down from the bar. Then she hung right in front of him. He stood on his tiptoes and kissed her lips. She grinned, kissed him back and said:

“I still have the set to finish …”

“I know … Don’t mind me. I’m just admiring the view.”

“You’re a dumbass, Tyler.”

“And you’re hot, but you don’t hear me complaining …”

They kissed, longer this time. Zoe was still suspended from the bar, her hard muscles maintaining her position with barely any effort.

“I have a stupid idea, Tyler …”

“Okay? What is it? Tell me.”

“Nah, it’s more of a demonstration …”

She lifted her legs up a bit, grabbed the waistband of his sweatpants with her toes and pulled it away, then dropped his pants. Now his cock stood nice and erect. Next, she wrapped her muscular legs around his midsection and pulled him closer while lifting herself up until her pussy was right above the tip of his cock. With a manic grin, she lowered herself down, using her inner muscles to pull him inside her. Tyler stared at her like a madman. He knew his girlfriend could be freaky, but … he had never expected her to be able to pull off something like this. He felt incredible as she started working his dick with her pussy muscles. Then she chuckled and added:

“Wait a moment …”

She tightened the grip of her legs around his hips. Suddenly realizing what was going to happen, he said:

“Please … don’t … or be careful …”

She closed her eyes, licking her lips, and then, lifted him up all the way, pulling herself up to the bar, suspending him under her while kneading his dick with her pussy muscles. Tyler would have cummed immediately if he wasn’t as shocked as he was by this display of insane power. He could barely see her face amidst those big tits of hers, but he could tell that she was close to ecstasy.

As she pumped out rep after rep, the stimulation of his cock only increased, and then, he couldn’t hold back anymore. He came, and that was enough for her to switch that pullup into a full muscle-up.

Tyler grunted as she hoisted him upwards, wondering just how crazy this would get over the next months …
