Draining the pool

Liz walked over to the pool with a gentle 'thoom thoom' as her feet made contact with the ground shaking it slightly leaving behind large footprints due to her new increased weight and size, with Josh holding on tightly to Liz's thick meat-pole as it bobed and swayed as she walked and from her rolling wide hips. He looked to either side of him to see his little sister's beach ball sized breast jiggling and sloshing with milk and swaying a bit from side to side despite being firm, taut and full of milk. Speaking of milk his eyes followed down from her huge jiggling breast to her ludicrously 2 foot long nipples each one partially covered by a piece of her old trousers that looked about ready to burst futilely try to stem the flow of milk constantly streaming out. Before then during their little 'special time' together in the gym he was just able to get his hands around her nipples just barely like a doorknob, but now it seemed as if he could just lay his hands flat against the tip of her phallic-like nipples with his fingers barely coming over the edge.

The thought of Liz's nipples being so thick he could barely get his hands to cover the tip was giving his penis hard again. Liz giggles. "What? What's so funny?" He asked rather curiously while making no attempts to hide his erection. "Nothing, I just remembered that when we were younger you used to give me piggy back rides. And now, look how the roles have changed in a BIG way." She said emphasizing the big which made her dick jump a bit but luckily Josh was holding on tight enough to not fall. "Although I don't think we can call 'this' (mentioning her brother literally riding her cock) a piggyback ride. We need a new name."

Josh gave a small chuckle. "Yea your right, and I still do remember giving you a piggyback ride, man how long ago was that?" He tried to remember the last time he gave his 'little' sister a ride on his back but so far has been unsuccessful but he does know that it has been awhile. "Oh I know!" Liz said breaking his brother out of his thought process. "We'll call it, COCK-riding!" She said proudly making said cock jump again. "Um no. Try something else." Josh said as he tried not to fall off his 'improvised seat'. "Dick-riding?" She said with a teasing smile. "How about something less phallic sounding?" Not that Josh disapproved of the names, in fact his own dick was getting harder just thinking about it. "The MAC DICKENS!" They both laughed at their play of silly names. "Yea just like old times." Josh thought.

"Alright we're here." Liz said as she came next to the pool. Truth be told tough she could have arrived her much earlier in no part due to her newer, longer and MUCH thicker legs. But she was purposfully taking her time just so she could have a conversation with a brother about the new'dick-riding'. Liz giggled as the once 'large' pool that she used to have trouble getting into now only came up to her knees. "I just keep getting bigger and bigger." She thought to herself as her column like dick hardened a bit at that thought.

Josh looked down from his sister's cock tower to see that their above ground pool still had water in it. His sister gave a sad look. "Ah phooey and here I was hoping to show my little baby brother how his big and strong sister would milk her thick and loooong nipples." His sister teased making said nipples jump at the notion squirting a bit more milk and straining the cloth piece even further. Josh was slightly annoyed now that his sister was going to call him 'baby' despite the age difference but his own dick had other thoughts. "Hey Liz, could you let me down so I could go turn on the pump?"

"Sure thing 'little' bro." She placed a hand on her dick which made her moan as her dick jumped again almost toppling Josh off but he held off. "Hey careful I'm still on this thing." He said a bit annoyed. "Sorry Josh, it's hhmmmmmm a bit more sensitive then usual." She slowly pushed her dick down until he was able to safely slide off it. He turned to say something to his sister but realized his mistake as he can now see his sister in a new light (both figuratively and literally).

As he looked up to his sister she looks more like a tanned amazonian goddess of war and fertility thanks to her VERY large muscles and 8 foot long, throbbing, erect cock with larger-then-basketballs sized balls brimming with virility. The Sun even made her skin look like it was glowing with vitality and health. All this only helps to further harden his dick, painfully tenting the shorts his wearing.

His sister wasn't just BIG but seems to be in much better health or even more healthier then he ever was with a dick that is no doubt more potent and virile then his. Is it possible that she is even more fertile then the average women? Is this all a part of her hyper charger puberty? He knows that the doctor said she would grow but nothing about her becoming better in other ways. Is she more special then either of them had given her credit for? So many questions floating around and for the first time, Josh felt something creeping up at the back of his mind. Inferiority. For now it was overpowered by his lust but he just can't shake the feeling.

Liz was wondering why her brother was just standing there gawking, she knows it was at her increasingly sexy body but he just seems to be staring off into space. "Uh hello? Liz to Josh can you hear me?" Josh snapped out of his stupor. "Wh-what oh sorry Liz. Was just thinking about something." He said as he rubbed his head. "I can tell." She pointed down at his painfully erect penis tenting his shorts. Josh blushed but made no attempts at hiding it. "Anyway I'm going to head in and turn on the motor. Wait out here for me." He said as he headed towards the large shed at the back. "Okey dokey little Josh." She said just enough for him to hear. There was no need for her to shout for her base or normal voice was now louder then when she was little thanks to her bigger and more powerful vocal cords. Bigger lungs also had something to do with this.

Now with Josh out of the way the bored 12 foot tall, 12 year now with a still erect 8 foot long dick has to find something to entertain herself with. She found an old wooden picnic table to the right of the pool where her family used to have feasts. She walked over to it and sat down next to it. When she did she sank into the ground a bit due to her increased weight. She giggled at three things:

One was that even while sitting down the table only came up to between her wide hips and muscle filled waist.

Two was that her butt was so big and firm it acted as an improvised cushion, lifting her a few inches off the ground as she was unable to lay her legs completely flat against it. It also didn't help that her legs were spread out due to the size of her enormous balls.

Three was that as she sat down her dick tilted backwards and now it's wedged between her massive breast, pressed achingly against her lips. "Ohhhh I so want to suck you off like the big meaty posicle you are, but I made a promise to my brother and I plan on keeping it." With that said she moved it aside so she could get a better look at her surroundings.

She laid her right, muscly arm on top of the table and, even though it creaked slightly, it held on. She raked her fingers across the surface and thought. "Speaking of popsicle I really am in the mood to suck something and also I'm kind of a bit thirsty." She looked around until her eyes landed on her leaky nipples. "Hey, I get to satisfy both my cravings AND I don't get to grow so win-win."

She grabbed the tip of her left nipple surprised that she could barely get her hands around it and shivered a bit in pleasure at how it has become even more sensitive then before. She brought it near to the side of her mouth. She didn't even have to pull her breasts up like she used to before since her nipples were so long she could curve them in a 'U' shape and bring it to her mouth and drink directly from her breast, straining the cloth piece, that was trying so desperately to stay on, even further.

'Normal' sized people would have trouble opening their jaw wide enough to even barely fit Liz's new larger nipples into their mouths. Liz is, of course, not normal. While she didn't have to open her jaw as wide as them thanks to her now larger head (to stay in proportion with the rest of her body) she did have to put some effort when nursing herself, luckily the nipple didn't go as far as her teeth and she sucking on it from the side of her mouth, surprising herself at how it tasted much better and creamier then before.

"Mmmmm ohhhhh I didn't think my milk would taste THIS good." She thought as she continued to suck, a strong stream of milk going down her throat as she was more taking small gulps then casually drinking.

Under normal circumstances Liz would look like a little girl sitting bored in the mall while she waited for her mother to finish her shopping, casually drinking from a juice box through a bendy straw while tapping impatiently on the table. But these aren't 'normal' circumstances, Liz is anything but little, her juice box is her over-engorged breast and her bendy straw is her thick, fleshy nipple.

As she continued to drink (or gulp in this case) her mind began to wander...
