Outgrown by sister and mother

"Hold on, rethink this ple...."

Josh had not a second to react to anything his younger sister & mother just agreed upon.
It all went by so fast and he was so dumbfounded and aroused by anything they were teasing about.

Of course it was too late.

The arms of his sister were not even close to being bent at a 90° angle, when she was already starting to spray cum from her stiff member directly into Joshs face, silenting him. "AAAAH HMmmm yes!! Ah this will be a bigger one, I can - mmmh - feeeel it, yes! But it's far from over so prepare, little Josh!" The doubled the strength she put in her arms. They started to vibrate intensely, as a second layer of darker, even thicker veins appeared all over her upper body.

Josh's mother on the other hand was still only spraying thin ropes of precum all over her own cock & the floor. She had her arms already bent to the max, but couldn't cum just from that. "Maybe I overestimated my own arousal" she thought. Although her shaking, fat cock was increasingly becoming wet and throbbing like crazy, her output was almost invisible compared to what was happening with her daughter.[

](http://body.In)In the brief moments his face was not covered by a new layer of Liz' cum, Josh inspected his sister's bloating arms and counted in his head:

"60 inches... 61... 62... omg sixty... eight?" The last number he actually stuttered in utter wonder. "Oh, are you looking at me brother? Hmmmh do I look... impressive?" Liz teased her older brother. Everywhere she looked she saw her own, pulsing body. Her view in every direction was obstructed by either her growing biceps or her swolling pecs as also her head was slowly pushed forward by her swelling trap muscles. Decided she couldn't see Josh's reaction anymore she decided to go with the 'flow', closed her eyes and cramped her head, which increased her efforts again. Veins were starting to appear over her forehead, as she was increasingly looking like a polished tomato. A giant, muscled, bursting tomato. In a microwave.

Her arms were now almost at a 90° angle, but she already could not look over to her mother to see how she was doing. "Doesn't matter" she thought. "If I just put 120% into this flex, my dick will come SO hard - there's nobody that could overpower me then, haha!" The flow of her cum was suddenly increasing and as if her body was trying to fasten things up, her cock throbbed once... then twice... then a third time, which made it grow 2 more inches each time, widening her cum-slit, as it was forcefully stretched by her increasing output.

"71... 72... 72.5? Hey your arms-" A rope as thick as a waterbottle hit josh in his mouth. "Ugh huh. *cough* -are freaking giant, little sis!"

Danielle was starting to sweat. Was she really losing to her little daughter? Wait... little?
She looked up for the first time in the last few seconds after they started their game. She has been too concentrated on her own cock that she was only now starting to recognize what was throwing a huge shadow on her.

Cracks were starting to trail around the feet of her little Liz, as she was giving everything for this stupid game she just had agreed to herself. She couldn't see Liz' painfully looking grimace as all she looked up to what seemed like a mountain of bulges, fibers & throbbing veins. Her muscles expanded outward so much, that Danielle had issues recognizing in which direction Liz was facing. Thankfully, her daughter still happened to own a cock that looked like 3 people being stuffed inside a sleeping bag. It was pointing at her older son, before it grew in front of her eyes until it was not pointing at her son anymore, but rubbing itself against him up & down the incline. Josh was shaking arms & legs around in panic being captivated by not only a dick as big as a boat, but a chaotic tornado of girlcum which continued to erupt from Liz.

"Ah. oh. OOOH!" Danielle suddenly realized that she herself was cumming. The pure sight of her sex-goddess of a daughter has made her loose all control, as her own trail of cum was joining her daughters. "MMmh I can... hah... still catch up I think if I cum a little more." Danielle calculated.

Josh was now full panicking. When his sister suddenly lifted her dick back up, he sticked toit for a few seconds, before being thrown off again by a huge cock flex of his sister, falling back into a pool of cum which now came already up to his knees.

"Hey girls, you need to stop - this is crazy! This is exceeding my wildest expectations. We need to give up our house and move if you don't stop... right..." He fell to his knees and stopped thinking when he saw a second fleshy volcano starting to pump gallons of juice in his direction.

Danielle moaned as she started to finger herself (and technically cheated) "STOP? Oh my little Josh this is not how I raised you! Never give up on your dreams! And right now my... mmmh... dream is to surpass your little sister and teach you both a lesson.... and I'm just... mmmh... getting starte- ah... AAAAAAAH!"

The cum flow from Josh's mother suddenly increased DRASTICALLY as Josh was thrown backwards into their now completely destroyed garden. In certain parts around the house the cum had already reach level of the windows, which started to show cracks from the pure pressure. The dark brown cock of Danielle was shaking uncontrollably. Danielle's eyes rolled up in her head as she threw her head back, thrusting her cock even further forward.

"Mom, stop it!" Liz suddenly screamed at her. "Don't be such a try-hard. You might be older than me but look at this-" She finally finished off her single, ongoing biceps-flex "AAAAAAH is TOO much POWER for... you...?" Inbetween her moans, her own cum flow increased AGAIN now at the peak of her grunting full-body flex. But as she was finishing her sentence, something entered her view, which was until now completely obscured by her own musculature. She gulped hard. It was her mother.

She wasn't lying when she said her powers were stronger. While Danielle was still coming hard, her height, muscles, boobs, ass & nipples all increased at an unbelievable speed. "YES! BIGGER! Mmmh Mommy needs these extra pounds - YESSS!" She had surpassed her daughter in height already, looking down at her, giving her a cocky smile. "Hey there sweety! It doesn't matter how much you'll grow, you'll always be my LITTLE Liz." Liz was angry. "Nnnnaaaaah!" She screamed in full anger, as her cock shot another powerful shot right THROUGH the incline, spreading grass & dirt in the sea of cum they both had created.

Josh tried to swim somewhere where he would be safe. He finally reached the ladder on his house that would lead to their second floor balkony and climbed it. What he saw from up there made his own pants burst open by his painfully stiff erection.

Two very very large moving objects were standing in front of him and his nose was only a few feet away from their jiggling, expanding asses. Objects - because even from his elevated viewpoint he couldn't make out their human proportions anymore. All he could see was hard-as-steel pulsing flesh that was creating a temperature as if Josh did just enter an oven. As the cum from both their cocks sloooowly became less & less, he could see the darker skinned one raising an arm for another biceps-flex. "God, I never knew what I was missing. Having the biggest muscles in the world sure rocks!"

Between them, he looked at the scenery behind. Their entire garden & the street behind it were covered & swimming in cum. 2 cars were thrown over by the sheer immense **** of his mother's & sister's cumflow. Small parts of the ground all around the area had little craters & holes, which were created when Liz' put extra **** into her cockflex. The windows of their house had given up on the pressure and the cum from the garden was now flowing into their kitchen & living room.

Joshs Mother & Daughter turned around, coming closer to Josh and rubbing their upward-pointing cocks against the balcony. Danielles' cock destroyed the fence of the balcony with its pure weight and a sudden throbbing of Liz' cock destroyed the glass window behind Josh, starting to spill pre-cum inside the house.

"How... How can you 2 still be hard?" Josh stuttered.
