The precum pool

Stretching herself standing inside the emptied pool, Liz was lost in her own thoughts - full of anticipation what would happen next to her, her magnificent body & her brother. Even mostly soft, her cock stood out between her muscular legs like a car tire, still dripping some precum from her latest - almost out-of-control erection. It flowed down from the tip of her human-sized flesh doll, the head still throbbing with every heartbeat as her tight foreskin was only able to cover 80% of her girlish meat. She noticed this - and looking down the giggled, swaying her hips from left to right, painting zigzag-shaped trails of cum on the floor of the pool.

Sitting on the edge of the pool, Josh snapped out of staring at his sisters perky breasts as he looked past them, seeing Liz grinning and giggling. What a powerful, yet so playful human being she was, he thought to himself. Wondering what she was looking at, he followed her eyes trail down. Right in front of his crotch, about 5 feet away from his legs, a creature that was about as tall as himself was swinging left & right, spraying precum all over the 6 ft deep floor of the pool. Liz giggling bursted into a short full laughter, as she was losing herself in her joy, now rocking her hips back & forth, which sent her oversized, yet fully soft cock into a chaotic swing pattern.

"Stop, you're..." Josh said "You're making a whole mess-" he was interrupted as a wave of sticky pre was slapping against both his legs like a warm, liquid whip. She's still the sister that I grew up with, he tought to himself looking back into her eyes. Liz, now letting her cock sway around and slap against her chiseled legs & steel 8-pack was histarically laughing and making animal noises, toying around with the newfound joy that being a god-like superbeing comes with.

"UUUAAAARGH, I'm cock-zilla, look at me gooo!" She screamed, bounving of her toes and sending shockwaves throuhg the ground.

"Haha, you need to-" Josh couldn't help but laugh about this a little himself. "-need to stop haha!" He couldn't deny there was a pure feeling of pleasure & joy to be gained from the absurdity of the situation as he noticed the heating sun being blocked by her swinging pole & bed-sized asscheeks as Liz was suddenly taking a few steps closer, just to balance herself out. "Woahah-" Liz spouted out as for a second, the pure weight of her cock being rocked in circular patterns throwing her out of balance for a second. "Haha, oh my god my body keeps getting out of control in different ways - even if I'm not aroused, like - at all. Hm..."

Liz hold on that thught for a second. She possessed a body that was on level with an alien creature - she herself still knew very little about it and what it was capable of and nobody would believe it if they wouldn't see it themselfs. Sliding her hands down her muscular, veiny abs she started swinging her hips just calmly left & right like when she started - rhythmic to the silent sound of the lustful music in her head. She started mumbling to herself "Maybe I should give up trying to control this-" she paused mid-sentece, erecting her arms slowly into a double-biceps-pose, giving them a casual flex, which sent a peak towards the sky which was almost at the level of her own head. "-when my muscles & cock really are starting to control me."

It took Josh almost 30 seconds to register what she just said, his brain felt paralyzed, staring at the wall of flesh that was erupting from her sister's biceps as she continued to pump them up, slowly getting faster. "No Liz, we've been through this! I know this is all - damn - extremely exciting I admit, but we can't go on like this so fast - we just know so very little about your powers and it's only day one! I'm your older brother and I kind of... feel responsible for you or-" the sudden twitching of her dick, which was now only 1 ft away from his body made him gulp for a second "-or any people you could might... harm."
His last words seemed to be directed more to her throbbing dick than to her sister, as his eyes were transfixed on it halfway through his brotherly advice.

Liz didn't stop flexing her mountainous biceps up & down when she looked down to Josh that was almost hidden by another Josh-sized creature she called her own cock. She stared down in his eyes for a few seconds, before she - instead of answering - gave him a playful, whiny look and then looked back at her left biceps. "Hnnnngh" she groaned as she flexed REALLY hard this time, her biceps growing 2, 3... then about 8 inches just from this beastly flex.

How can she just not answer me - I'm the older brother! Josh thought just before his mind drifted back to her crotch where Liz sweaty cockhead was about half-uncovered by her foreskin and producing more & more precum, sending extra strong waves splashing down to the pools floor when she was at the peak of every double-bicep flex.

"If you say so." She said.

And as she was giving her most defiant look yet, she suddenly lowered her arms quickly and sat down in the precum-drenched pool with a bit too much speed & strength. Her clapping ass cheeks created a shockwave so strong, that a piece of garden fence collapsed and the window of Joshs room on the second floor showed a spider-like crack.

Josh himself was thrown off the edge of the pool, face-down towards the floor. He burst out in a quick scream, before his mouth was stuffed with white-stained translucent goo, which dampened his fall. When he jumped back up, he felt a bit too relieved that his nose was not broken to notice that now his entire frontside - from forehead to toes - was drenched in his sisters' juice. Liz covered her mouth with a hand to hide her intense giggling.

Josh seemed not amused by her reaction. "Hey! You see? I could have broken a leg or smth just now... And look at all this mess!" He pointed at - well everything. The entire floor of the pool was covered with smelling precum that rose about 8 inches from the ground.

Liz pressed her feet against the pool wall that Josh was leaning against so he was surrounded by tree-sized legs, which flexed in rhythm with her breath. She was leaning a bit forward to listen to her brothers rant and gazing at the amounts of precum she already produced by... not even being aroused much. While her legs were spread this way, her dick was lying soft on the ground, her cockslit about at the level of the precum. Josh was mesmorized, when he noticed how her dickhead seemed to be breathing with her, sucking in & releasing new precum in a hypnotizing pattern.

"Just imagine how this would end like when I'm not here to control you and you would... you know..."

He was interrupted by Liz suddently standing up straight again, her ass and balls dripping of massive amounts of precum from the pool. Josh was not sure, but he could feel like she intentionally positioned her pumped up legs around him, so her the head of her cock, creating bubbles of sticky juice was throbbing just inches from his face. Half of her body was still covered in dripping liquid that ran down between her asscheeks and painted her leg muscles in a glossy texture. Josh felt like he was standing at a bus station during rain.

"You know... er... cum for real?" He was whispering the words and immediately regret it.

"MMmmmh" Liz moaned as her cock made a noticable jump as the pure thought made her cockslit widen, which drenched Joshs precum-covered face in a new, way more thick layer of goo that now drenched over his entire head, down his shoulders and his back. Still without a single touch, her foreskin seemed to be pulled back almost by 80% now, when the basketball-sized tip finally came to a rest on top of Josh's head.

"Yeaaah..." Liz seemed like she was in another dimension. "I do imagine that."
