Bigger And Better

Author's Note: Well, I'm very excited to say that this is my first commission piece! The person who commissioned me wanted to be left anonymous, but it was a lot of fun working with them to create this! They had a lot of great ideas and I'm proud of how it turned out. Also, I don't know how many readers pay much attention to the lore in my stories, but for those who do, I should clarify that this isn't a part of that. Takes place in our world with futanari and whatnot. Hope you enjoy what we put together!

"Come on, James! Just a few more reps!"

It was a struggle, but James could feel his muscles straining as he pushed the barbell up and away from him. Even his veins bulged to pump more blood to his muscles. He did one, then another, and with the help of his sister's encouraging words, James managed to bench a few more reps before pushing it up to racket it.

A moment before he made it, his arm gave out from the weight, and nearly dropped it on himself. But Karina caught it in time. She picked it up and set it on the rack for him.

"I don't know how you can bench-press 390," James muttered before chugging some water. "I'm still struggling to reach 320."

Karina sat down next to him and squeezed his shoulder with a firm hand. There was a bit of amusement in her voice. "We might be twins, but how could I be a good spotter if I wasn't the stronger one?"

Yeah... stronger, bigger, taller... sometimes it felt like anything he could do, she could do better. He didn't have to round up to say he was six feet tall, yet Karina still had a good few inches on him. Though he couldn't be too hard on himself. Unlike Karina, he at least had a girlfriend.

"Plus, I kind of do this for a living." Karina stood up and grabbed some cleaning supplies to wipe down the bench. She liked to make sure their equipment was squeaky clean between uses. "Maybe if you became a personal trainer, you could catch up."

James laughed. "And give up the great pay at my job?"

"Great pay?" she said as she cleaned. "If either of us made decent money, we wouldn't be stuck living at home."

She had a point. With how the economy was, neither of them could afford to move out. The extra cash did help set up a great home gym, but James desperately wanted out. It was hard to decide what was worse about his living situation, having his sister's cock in his face every time she spotted him or all the noise from their parents fucking every night.

"Yeah, I guess." James wiped his face with a towel and stood up to let her finish wiping the bench down. "Want me to spot you next?"

"If you think you can handle it," Karina teased.

James rolled his eyes as Karina pulled the weights he used off the barbell. It was a little annoying seeing how easily she carried them back towards the rack. As if it was nothing. When he brought them over earlier, he needed to carry them separately.

So, it made him smile as he watched Karina carry hers over one at a time too. But when he noticed how much they weighed, his smug smile faded. "You've gotta be shitting me. 400 pounds?"

"Can't get any stronger if I don't push myself," Karina said as she locked them on the barbell.

She sat down and wrapped protective straps around her wrists and elbows before applying chalk to her hands. With how hot the room was from their workout session, the two of them were drenched in sweat.

James stood over her, hands ready to catch the weights in case it was too much, and watched as his twin bench-pressed more than he ever could. Not only did her massive arms bulge to hold such a weight, but her abs tightened as well. It was almost hypnotic to watch her muscles ripple under her skin as they shifted between pushing and lowering.

As she pumped out a few reps, sweat trickled down her body. It soaked her sports bra and even started to form a puddle on the floor as it dripped off her arms. Even more began to run down her body as she struggled to finish her last rep. But unlike with James, she managed to rack the weights without any help.

Damn, he wished he was that strong.

"Another great workout," she breathed and sat up.

As she wiped her face with a towel, James couldn't help but feel inadequate. "Same time tomorrow?"

"Tomorrow?" she set the towel to the side and leaned back on her hands. "Hmm. Think I'm booked tomorrow. With summer almost here, my regulars have been scheduling a lot more. Especially that one girl..."

"Lia?"

"Yeah, that one! My god, the tits on that one," Karina sat up and motioned with her hands. "Just wanna squeeze them while I pound her from behind."

James felt his cheeks burn a bit, making Karina roll her eyes.

"Like you don't have the same thoughts about Erica." She stood up and quickly wiped down her mess. "Speaking of which, she has an appointment with me in a couple days. So, don't let her forget."

"She does?" Erica didn't tell him about that.

Karina ruffled his hair on her way to their locker area. It was just a couple of lockers by the door for the two of them and her clients. "You don't have to worry. I promise I won't do anything to her except help her keep that body you like so much."

"I know..." James said as he grabbed a change of clothes. "Mind if I shower first?"

"Yeah, I'll handle the cleanup."

On his way to the shower, his thoughts grew more skeptical of his sister. She said she wouldn't do anything, but that didn't clear the air like she had hoped. Probably because of that time in high school when he caught her sleeping with his girlfriend at the time. The same night he was supposed to be celebrating a big win for their school's football team.

James shook his head. A shower would help clear his mind. He passed by the kitchen and tried to ignore all the moaning and slapping noises coming from it. Again. Their parents just couldn't wait for bed like normal people, they had to go out where they could be seen and heard.

"Blair..." their mom moaned. "I'm close!"

"Oh, I know," their dad laughed. The sound of a firm slap, quickly followed by a loud moan, echoed out of the kitchen. "I can feel you squeezing my cock."

The sound of their fun dampened as he stepped into the bathroom and closed the door. His reflection stared back at himself in the mirror as he waited for the water to warm up. He struck different poses, watching his muscles bulge and flex beneath his skin. Karina might've had his dream body -aside from her tits, but he was still content with his build. Erica enjoyed it enough to drool over him.

When the water was hot enough to steam up his reflection, he quickly stripped off his shorts and boxers and hopped in the shower. Though the water was nice and hot, there was something he needed to do before washing anything. He gripped his cock and started stroking it. A good workout always made him rock-hard afterward.

Karina might've been bigger in every way, but James was certain this was the one thing where he was the bigger twin. He had the advantage of being a man. And there was no way a girl could beat a guy in a dick-measuring contest, right?

Thoughts of his girlfriend ran through his mind as he stroked his cock. Erica wasn't just beautiful, she was

hot

. Especially her tits. Those girls were big enough that he could barely get his hands around them when he played with them. And she made the cutest noises...

James couldn't hold it back anymore. His hand furiously pumped his cock until he blasted a couple ropes of cum into the shower. As it washed down the drain, he placed a hand against the wall for support. Blowing a load always took a lot out of him. He needed a minute to regain his strength.

As he took a steadying breath, he smiled to himself. Once again, he wouldn't have to jerk off to some nudes she'd sent him. Karina said she was going out; supposedly, their parents had mentioned going somewhere too... and he and Erica had a date night planned. Meaning they'd have the house all to themselves.

Excited for the night, James quickly finished his shower and stepped out to dry off. He put on some casual loungewear, like a t-shirt and sweatpants. Nothing too fancy for their movie date. After all, it's not like he was going to be wearing them for long.

A knock sounded at the door. "You gonna stay in there jerking off all day, or can I take a shower?"

"Relax, it's only been like fifteen minutes. Unlike your hour-long ones," James said as he wrapped a towel around his waist.

As he combed his hair in the mirror, Karina barged in. "Yeah, yeah, I don't have time to rub a few out tonight. Just don't want to go to the bar smelling like a gym."

"You'd be surprised how many people are into that." James turned to look at her, but ended up getting hit in the face with a wad of clothes.

"Get out, or I'll have to strip in front of you," she said and hooked her fingers in her gym shorts. A mischievous grin spread across her face. "You know, you'd be surprised how many people are into that."

James rolled his eyes and left.

Not too long later, Karina was gone, and their parents left for the night. The house was empty. Until there was a knock at the door. James opened it to find Erica standing there with a smile. Her skirt was just long enough to cover her ass, and her crop top had a neckline so low that it left little to the imagination. Especially since it looked like she decided not to wear a bra.

"Hey." Erica stood on her tiptoes to kiss him, but James still had to lean down a bit.

He wrapped a hand under her ass and picked her up as he closed the door behind them. His tongue invaded hers, desperate to have a taste. Erica's leg lifted against his hip, letting her lower lips press against his growing erection.

Before anything else happened, Erica pulled back with a blush. "That was quite the welcoming."

"If you liked that, we could skip the movie and go straight to the bedroom." James set her down.

"Boys." Erica ran her hands across his abs. "Always quick to get into a girl's pants."

James placed a hand on hers while the other hand pulled her close. "Like you didn't try sucking my cock the moment we met."

"Not my fault you've got such a big boy down there," Erica padded towards the living room, towing him along.

Since they had the place to themselves, James had taken some time setting the mood. Lights off, candles lit, and a cheesy rom-com ready for them to ignore while they had some fun.

James joined her and sat down on the couch, leaving room for her to plop down next to him. Close enough that she was practically sitting on his lap. Her golden hair fell against him as she rested her head on his shoulder. From the way she leaned against him, he had a pleasant view straight down her shirt. God, those tits were big. They were practically begging him to squeeze them.

But he stopped himself and instead hit play on the movie. She

did

want him to take his time after all. To slowly get that tight pussy wet and ready before hopping on his cock.

As they watched, occasionally making comments, James slid his arm around her waist. It made her place a hand on his chest again and snuggle closer. She was so small that it was hard not to pin her down and have his way with her, but it was fun drawing it out. Watching her face blush at his touches.

James's hand slowly moved to slip under her shirt. He trailed a finger up until he reached a breast. She gasped as he cupped it. It was too big for him to hold fully, but soft enough to sink his fingers into.

She made the cutest noises as he gently fondled her. Soft humming when his hand moved, a gasp when he squeezed, and a quiet moan when he played with her nipple. The sounds of it all made him rock hard. His cock throbbed painfully in his pants for more.

Forgetting the movie completely, James placed his other hand on Erica's thick thigh. While her waist was thin, her ass and thighs were thick enough that they always bounced nicely when he'd pound inside of her. His thoughts lingered on the memory of the last time he did that as his hand slid up under her skirt. It was short enough that he could see the wonderful shape of her mound through her wet panties.

Two fingers touched it, running up the indentation of her slit to her clit. Though he made sure not to touch it just yet. His fingers swirled around it and ran back down. After a few trips, making her squirm, he pulled her panties to the side and rubbed her slit directly. They teased her tight entrance, pressing against her as if to push inside before pulling back. Once wet with her juices, he gently rubbed her clit in small circles. Her squirming grew more desperate as her moans grew louder.

Before he could do anything else, Erica lunged at him, mashing their lips together in a passionate kiss. Her tongue wormed its way inside of his and swirled around until she pulled back, gasping. A strand of saliva hung between them.

"Just fuck me already," she breathed.

James looked down at her with a knowing smile. "Thought you wanted me to take my time."

Erica fell back on the couch as she slipped out of her shirt. With legs together, she lifted them to slide her panties down her smooth skin. Strings of her fluids clung to them before she slid them further down her thighs. It gave him a small, pleasant view of her pussy before she spread her legs.

As James crawled over her, she reached down with a foot to cup the bulge in his pants. "You gonna complain or you gonna stick that big cock of yours inside of me?"

She could be

such

a size queen.

James quickly undid the front of his pants and pulled his cock out. A proud seven-incher, seven and a half if he was really hard. Every now and then, he would measure it to remind himself just how big he was. He slapped it down against her slit, earning a cute moan.

Erica placed her hand on his abs, stopping him. "Wait. Do you have a condom?"

Shit.

"I do," he said and grabbed one from his wallet. She made him wear one every time, but he wanted to know what she felt like. To feel her around him. "You sure you don't want me to go in raw?"

"Is that okay?" A bead of precum ran down his length as she put the condom over his tip. "I love you, but I want to wait before we do something that risky."

James sighed to himself, but didn't push her. One day he'd fuck her without one. Until then, he waited for her to roll it down his length, then pushed his cock through her hand and into her waiting hole. Erica yelped in surprise as she took a couple of his inches.

"Such a nice cock," she purred.

With a smile, he pushed in until he fully hilted himself. He started thrusting, nice and slow, when the door suddenly flew open. Karina walked in with a shorter girl clung to her side. From the way the girl walked, she had been drinking a bit.

Karina paused mid-step as she made eye contact with James. "Am I interrupting something?"

The shock of someone walking in had made Erica duck down. She wrapped an arm across her breasts and poked her head back up to give a small, nervous wave with her free hand.

"Hey," Erica said just loud enough to hear.

"Whoops!" Karina quickly led the girl towards her room. "Sorry, just ignore us."

Once they left and closed the door behind them, Erica collapsed back against the couch with cheeks bright red. She seemed strangely nervous around his sister.

"You good?" James asked.

Erica's eyes flicked back towards Karina's door, then back to him, and nodded. "Just wasn't expecting company."

Cock still buried in her, he swore he could feel her getting wetter. It made him want to keep going, so he did. James started gently thrusting into her again. Feeling her tight pussy squeezing around his cock. She bit her lip and moaned when he hilted himself again, but her eyes kept flicking back to the door. Distracted.

He knew what could help with that. James leaned down, pressed his lips against hers, and went all out. Hard enough to make slapping noises as his hips connected with hers. Fast enough to make her tits bounce around.

That

had brought Erica back around. Her arms wrapped around his neck as she gasped between passionate kisses. Sometimes a small moan to keep him going. His hand in turn reached down to grab her breast, squeezing it until he earned a moan.

Their hands roamed each other's bodies. James ran his hand up Erica's thigh to her smooth stomach, then slowly up between her breasts. Her breathing grew heavy at his touch. His hand moved higher to run through her straight hair. Golden like the sun.

With Erica on bottom, she had two free hands to feel him up. They started just above his cock, feeling his abs as he thrust into her. She made sure to feel every crevice before sliding up to feel his pecs. His were hard as stone from all the training he and Karina did together. And Erica loved feeling them. She had a thing for big, strong lovers.

When her hands made their way to feel up his biceps, he gave them a flex. Something to add some heat to their love. It made her wet enough that her juices splattered across his thighs with each thrust.

Before too long, James could feel himself getting close to the edge. That feeling slowly built itself up until he couldn't hold himself back for long. Erica clung to him, hips grinding in sync with his thrusts as she grew closer to her own orgasm. But James couldn't stop the incoming rush of emotions. She just felt so good around his length.

When he pushed in for a final time, James held her waist tightly against him. Hand squeezing her plush ass as his balls emptied inside of her. His load might've been blown into a condom, but he imagined it spewing inside of her. Filling her up with his seed.

His cock slid out with a pop as the condom came out with a sizable load. He quickly pulled it off and tied it, letting it fall to the floor so he could finish her off with his hand. Most of the time, James could get her off before he blew his load, but now and then, he'd end up finishing first.

Fingers ran along her slit to lubricate them before slipping inside where his cock once was. She was loose enough now that two fingers could fit. They thrust in and out, stroking and pressing all the spots he knew she liked. And as he felt her getting close, he slipped a third finger in to help out.

Erica clenched around him as she groaned out an orgasm. One arm draped across her face. She heaved as James let her go and laid back against the couch with a satisfied smile.

He placed a hand on her leg. "How'd that 'big cock of mine' feel?"

"...good," she said as she lay there for a long second. Then, sat up and took his hand with a smile. "As always."

James opened his mouth, but that's when the moaning started.

***

Karina closed the door behind her to give her and James some privacy. While he'd spend some time fucking Erica on the couch, she would have some fun with Lia in bed. One of her clients she happened to run into at the bar.

Lia was still dressed in her work clothes. Simple button-up shirt and a pencil skirt. She was a cute little thing with black, silky hair that went past her shoulders. Really nice tits too. It was hard to hide her erection any time she had Lia in the gym. After helping her work out for the past few weeks, Karina knew exactly how much that body could take.

The girl started climbing into bed when she noticed Karina hadn't moved. She still stood near the door with hands on hips. Karina raised a hand and beckoned her over with a finger.

Lia opened her mouth, a question on her face, but Karina silenced her with a finger. "On your knees."

Without a word, Lia obeyed. The view of a cutie like her on her knees- flushed face with hands in lap, was a wonderful sight. Karina stood with legs apart as her hands moved to the front of her jeans. She watched the girl's face as she unbuttoned her pants and hefted her sizeable cock out. It hung between her thighs like a large pendulum.
