The milky pool

"You might want to get some swimming trunks Joshy." Liz said snapping Josh out of his trance. "Huh, what why?" He asked groggily, still reeling from the whole ordeal. "Well I am going to be filling up the pool and we wouldn't want all of that to go to waste now do we?" She teased, watching his tiny cock jump against the tight shorts. "Ye-yea, sure." He slowly wobbled his way towards the house, taking one last look at the tanned amazon know as his sister. He did a double take, he cannot tell if it's a trick of the light but he could have sworn that Liz's usually brown colored eyes were twinkling a faint golden glow. "*Groan* I can't be dealing with this right now, it's already too much." He thought to himself as he made his way to the door, which before he entered, pulled back up the fallen collapsible door and fit it in place before retreating to get his trunks.

With Josh out of the way Liz looked back at the now empty pool and down at her breasts. "Alright my 'little' titty friends, time to see what your truly capable of." She walked over to the pool and bend down from the hip at a perfect 90 degree angle so her breast are directly above it. This made her large, glistening ass stick further out, bare for the world to see. She pinched each of the cloth tubes and in a single motion, ripped them.

Fwoooossssssh

Her milk came rushing out of her nipples in twin, thick streams. She grabbed each of her nipples to prevent them from flailing around like a hose and aimed it down at the pool, rubbing them up and down in order to increase the already high flow of milk. "*Moan* This feels so good *groan*it's like I can FEEL my milk rushing out and yet I don't even feel warmed up yet. Ohhhhhhhhh it's like I'm making more milk then I'm expelling." Liz simply stood there, moaning and groaning in pleasure as she was quickly filling the pool and shaking a bit and as a result her meaty pole was starting to harden and rise a bit.

Back in Josh's room he was stumbling here and there trying to look for his trunks. "Come on where is it, I remember it was here last time." He walked around a bit until he finally found it in a small pile of clothes. "Hey. there you are." He said picking up the red colored swimwear, or more specifically, swim briefs. He got undressed, now Josh was by no means a skinny kid, he did have some nice muscles with a faint looking six pack and a respectable bicep. But compared to his big little sister now, she made him look emasculated. He put on the briefs, he now remembers why he doesn't wear it anymore, it was a bit small and as a result showed a prominent bulge where his dick is.

"Well it's kind of inevitable that we are both going to be turned on by this." He looked up to his dry, crusty bed that Liz ruined with her 'milkgasm' and is in dire need of cleaning. Speaking of Liz, Josh was wondering what she was doing exactly. He took a curious peak outside his bedroom window into the backyard expecting to see his sister, but instead he was greeted by a gigantic, jiggling ass staring right back with with her larger-then-basketball sized balls directly below that might as well qualify as a second butt from how big and round it is.

Liz looked over her gigantic ass to see Josh staring at it through his window, smirking she repeatedly flexed her gluteus making her massive butt cheeks (and to a lesser degree, her balls) bounce. He was instantly hard with his dick making a clear outline against his briefs with a dark spot already forming at the tip.

"Dammit, I can't even look at her properly without getting an erection now." He looked around his room some more until he spotted an old box lying in the corner, away from sight. Curious he walked over to it and opened it, inside he found a lot of strange knick-knacks that he has collected through the years, one in particular is a pair over sized bottle corks. He then got an idea, grabbed the corks and went outside.

Normally it would take at least a few hours to fill the pool on average, but with Liz's twin, cannon like thick super-nipples expelling high pressure milk at record speed, it is being filled in a matter of minutes. She heard Josh running up behind her. "Hey Liz, when your done I have an idea on how to stop the milk." He said. Liz never really made any real attempt at stopping the flow of milk since all her solutions were half-hearted and on the spot, not really thought through, like the cloth strands which she just ripped.

When the milk level in the pool was nearing the top she clamped down hard on each of her thick nipples using her hands, stopping the flow of milk temporarily. She turned and looked down towards her little big brother in nothing but his little red swim briefs which made a pathetic attempt at hiding his erection with a dark spot that was slowly growing at the tip. Liz smiled in both amusement and lust at this display and just when her own dick was starting to harden, her brother held up what appeared to be two larger then average bottle corks. Liz was confused by this and asked what were they for.

"Their for your nipples silly, now bring them down for me." Liz complied and bent forward a bit, aiming her nipples at him. The difference in size is pretty embarrassing to say the least, Josh ignored it by his better judgement and proceeded to plug his sister's nipples with the corks. She moaned a bit in pleasure but that's just about it. When he was done the corks were fitted nicely into her nipple holes. Liz slowly released her grip on her nipples and as she did... nothing happened. The corks worker!

Josh looked up at his sister in slight worry. "Do you... feel anything?" He asked. "Well I do feel kind of a slight pressure building up but other then that, nothing else." He sighed in relief and looked towards the pool. A pool filled with his own sisters milk in only a matter of minutes. He looked back up at her beach-ball sized breasts, those two giant milk factories are actually capable of producing AND expelling milk at such a rate that not even a hose at high setting would be able to compete or even come close, how is any human capable of even doing that?! He gulped at this, both in lust and also a bit of dread, he just had to know.

"So uhhhh *gulp* how do you feel after ummmm... milking yourself?" He asked hesitantly, worried about the answer. Liz on the other hand, simple shrug her massive bowling ball like shoulders. "Actually I don't feel any different, it's like my breast hasn't even been milked in the first place." Josh was taken aback by this. No difference? Does that mean her breasts were just as full as they were before? Does that mean she would have actually been able to flood the house if she didn't stem the flow? Josh was becoming a bit unsteady at this new piece of information and Liz noticed. "Hey take it easy, maybe you should take a rest and have a bath... in the pool." She said concerned with a slight bit of tease, it was becoming harder for her to not tease her rapidly diminishing brother for it was becoming a routine and slowing integrating itself as part of her personality. It was simply a byproduct of her fantasy and lust driven mind combined with her ever growing body.

Josh however, was in no position to argue and slowly made his way to the edge of the pool and climbed in without a second thought. The milk came up to just below his chest level. Still a bit woozy he walked towards the other side of the pool with a bit more effort due to the resistance in the liquid, turned 180 and leaned his back against the side of the pool resting his arms on top. He was still trying to process everything that has happened since he woke up as it all came crashing down on him like a ton of bricks. His 'little' sister stands at a massive 12 feet with muscles that could put a bodybuilder to shame, a cock as big as a human and just as strong as Josh was able to sit comfortably on the head while it was erect and he was by no means light, testicles as big as basketballs and as the bigger they get the more semen they are able to produce or probably even more, boobs as big as beach balls and so perky that they defy gravity, producing WAY more milk then their appearance suggest, a massive, perky bubble butt that prominently sticks out of her body and could even be peaked over from the front due to just how massive it is and so jiggly that one would have thought it was made of jello.

All this and not including the fact that she now has a new 'ability' to grow specific parts of her body to her desire after drinking her own milk and that she is able to store larger quantities of it in her belly and not show the slight bit of discomfort. Non of this the doctor has ever said, but then again even he was a slight bit surprised to find the development of Liz's nipples, something he wasn't expecting. Josh was slowly but surely, gaining back some of his composure but there were still some questions left unanswered. How was Liz able to store that much milk in her belly without any discomfort? And from what he saw it was almost as big as her breasts! So how was her breast able to store that much milk? Or maybe they can't and that's why they are continuously leaking because they are producing more milk then they can store. But if that's the case then how fast can they produce it since one moment it can slow with just a bit of trickle or it can be so fast that it fills the pool in a short time. Is it because Liz milks herself and is in a state of arousal that they up their production?

So many questions, not enough answers. Josh was able to break away from his thoughts just when he heard his sister say something.
