Twisted minds

"My turn to get in the pool." Before he could voice his protest his sister raised her column like leg, muscles involuntarily flexing and bunching up, looking like their about to explode, before she slowly dipped her leg into the pool. Already a lot of milk is being displaced over the edge creating small waves and heavily splattering against the grassed soil. She moved forward to place her other leg in, her dick dragging over the edge before falling into the pool with a wet *plop* sending shivers of pleasure through her as she failed to suppress a moan with her meat pole twitching, making tiny waves around it.

Now with both her muscly legs, plus one meaty, oversized sausage in the pool, displacing a lot of milk over the edge making a dark patch around the pool, the milk level only came up to her knees. Liz smirked in amusement at this as she moved into a siting position on the other side of the pool, directly opposite and facing towards Josh. In the process of sitting down she was making large waves with enough **** that Josh had to hold on to not be thrown around. Liz giggled at this as she laid back with her arms on top of the pool as it audibly creaked to support her massive size and weight. The pool was by no means big and so when Liz spread out her legs it reached the two opposite corners of the pool either side of Josh with her meat cannon directly in front of him that was, for now, soft and below the pool level.

Josh was essentially trapped between the pool corner and a hard place but he didn't know of this for anything below the milk level was blocked from view because of the white milk. Liz 's legs were once again not laying completely flat on the pool floor for her massive, perky butt raised her a few inches up. Liz looked around her but had a look of... disappointment on her face because even when sitting down the milk level only came up to just below her bellybutton. "Well a giantess can't be choosers." She said to herself.

"You said something?" Josh quipped. "Oh nothing, just talking to myself." She giggled, Josh gave a look of confusing before shrugging it off and laying back to relax. Josh decided to examine the milky pool since it felt much different then normal water pool. The first thing he noticed was that the milk was more viscous then water thus more effort was needed to move in it, the second was that the milk was unusually warm, just enough for one to be fully relaxed in, bordering on sleep, the third he almost missed but was definitely there, was that the milk felt different on his skin then chlorinated water, he didn't know how to explain this but it felt good so he let it slide.

What Josh didn't know was that the milk was having a moisturizing effect on his skin, revitalizing it, making it younger, smoother, softer, but these effects were subtle on Josh, almost unnoticeable, a 'blink and you'll miss' moment that would make practically no difference. But Liz however with her hyper charged puberty, combined with the effects of the milk AND the energizing rays of the Sun is about to have some profound effects on her skin.

"Mmmmmmm, oh I feel tingly all over *grunt* and I think a friend of ours wants to come out and play." Liz grinned, Josh dreaded but also anticipated on whats to come. In front of him he saw a dark form in the pool that was slowly getting bigger and lead back directly to Liz. Slowly, like a kaiju rising from the ocean, the monster rose from the pool, milk dribbling off of it, staring down a dark, pitch black hole that held it's true power at the base, yearning to be released, to prove it's dominance and to cement itself as the one true ruler to conquer them all. Josh stared down at this beast, for the first time feeling fear at this monster of a cock, feeling ashamed that he has the same organ but no where near as glorious as this magnificent beast. The beast audibly throbbed, for a second getting closer to his face as Josh shrank backwards, even his dick laid down it's head in honor, fear and respect of this king who is deserving of it's title. He could actually hear it's cum gurgling inside, echoing from it's open hole making it sound like the beast was growling as it continued to produce increasingly potent seed where even a single drop would be enough to impregnate a harem worth of breeders.

Liz looked down at her brother who was shivering in fear as he looked at the monster of a cock, that was aiming directly at his face, that proudly belonged to her. Liz, for the first time without even thinking, gave a condescending smirk. Liz snickered. "Better get used to it dear brother of mine for it isn't going down anytime soon until we're done." She said with a hint of superiority in her voice. Josh shrank further into the corner, fear in his eyes. "Su-sure Liz, what ever you say." He couldn't think straight for he was too afraid to talk back, Josh never really liked confrontations but being in one right now, especially since it's coming from his big little sister, it was something else, fear combine with lust for his sister's body, a truly tortures ordeal. He laid back as he tried, and failed, to relax while continuing to stare at the hungry beast that looks ready to swallow him whole.

Liz just now realized what she has done, she should feel guilty, bad, sorry for herself. But she didn't, with her hormones and lust continuing to twist her mind she felt, powerful, dominating, superior. She laughed at the sheer ridiculousness of the situation, at her midget of a brother as his will is slowly chipped away while his too afraid to move but too fascinated to look away from her monster of a cock. "Hmmmmmmm monster cock, yes that sounds lovely." She thought to herself as she put a mental pin on it for later. She closed her eyes and laid back to relax, the pool protesting against her but she didn't care as she gave a deep sigh and was lost deep in her thoughts as the rays of the sun shine down upon her resting form.

Josh however, now had to deal with said monster cock staring him down. It was like it has a mind of it's own as it continued to stay erect only occasionally bobbing up and down, as if to make sure he stays in his place. It was not until he gathered his courage that he finally managed to look away from the monster and onto his sister's titanic form. She was resting with her eyes closed and her head laid back onto her trap muscles, acting as improvised 'pillows' with a smile on her face, but this smile was... different. It's not the same smile she has when she goes to bed and snuggles cozily in it, this was the smile of a dormant dominatrix, a different beast entirely just waiting to be released. Who is this being that has taken over his sweet sister's mind?

He didn't know what to do, all he can hope for is that when she wakes up she's back to her normal self. For now, Josh just stood there, at the mercy of his sister's meat cannon. Even though he managed to gather himself up, he still felt jealous and ashamed that his sister was bigger then him in literally ever way, even in the one department that he thought was exclusive to males and said 'department' is audibly throbbing. With nothing else to do Josh decided to do something a bit unhygienic. He cupped his hands in the milk and brought it to his mouth and took a sip, or gulp in this case. "Hey, that's not bad. In fact it tastes even better then last time, creamy and a bit thick. No doubt this would fill me up in no time."

He looked back at the cum cannon only to realize something. "Is it... darker?" He said more to himself. The dick was indeed more darker, now a more light shade of brown. He looked over his sister only for his eyes to go wide and his mouth to go open. His witnessing his sister's already tanned skin, tan even further. The combined effects of the sun's rays with the moisturizing milk and Liz's hyper charged hormones was having an accelerated affect on her. Her skin color turned to a dark shade of brown with an exotic, golden tan that glowed when the rays shined down upon her giving her the look of a native, a real, living, native amazonian Goddess. If she didn't look the part before she definitely does now and she delivers it in spades. No tanning bed would ever come close to giving this level of perfection. Her skin smoothed over, losing it's roughness and becoming softer but still retaining the hardness and ridges of her massive muscles. Back to her cock, it was a much darker shade of brown then her skin, which ironically made it even more imposing. Her areolas seems to have also darkened to the same shade as her cock. She looked like a real native now for it is impossible to obtain this level of complexion unless she was born, raised and lived in the jungle her entire life. But she didn't, instead it was all thanks to her glorious body and super puberty that would turn Liz into more then her ideal self and more then just a mere, pathetic human being.

Josh was having a hard time staying focused, he just witness his sister change skin color right before his very eyes and in such a dramatic way his own, pathetic dick was straining painfully against his trunks, yearning to be released, to be with this Goddess, to be inside of her in the smallest of hopes it would be able to impregnate her with it's children if it weren't for the dark beast that guarded the only entrance.

Before Josh could think of anything, his sister woke up.
