Longer and heftier cock

"What...oooh.....it was.. oooh....just...oh God.. your...precum?" Mum is able to say between her son's thrusts.

"That's right mum! Here comes the main heavy load." John feel how the cum build inside of him and he is ready cum now.

"Wait...wait...son!" Mom says but it is too late. John's cum bursts from tip of your 61 cm (2 ft) long and thick penis and fills his futa-mom pussy.

"Uaaargh" Is all his mom says as her body went limp and she almost pass out. She and John fell on his mom and dad's king sized bed.

Both of have used so much energy that you take a short nap.

John wake up when he hears his mom giggling a little. He look at his mom and saw her caress her huge and hard futa-penis and her full and juicy testicles. There was still his cum on bed sheets and under both your bodies but that does not bother John or his mom.

"This so humorous." Said mom while she squeezed and caressed her futa-organs.

"What you mean...?" John asked and rose to sit up.

"Well it so funny that even if you tried your best your male cock is so small and your heavy load of cum dose is not really so huge." Mom said and John sees how mom's penis begin to harden and stiffen even more.

"Huh?" John said but he knows he could make his cock bigger easily. Just with the snap of his fingers.

To John's surprise Mom burst to laugh "I meant our balls are almost at the same size but my flaccid cock is almost as big as your hard one. My heavy load of cum could fill easily a inflatable small pool which small kids use at summer. Plus my semen is not watery like your's, mine is thick like a cream."

John gulped loudly and begin to realize his mom is not a normal human anymore. He look at his mom but then his gaze nailed on mom's lower body. He sees mom's penis grow longer, heftier and testicles grow bigger by second. John went pale as he realizes he have created a monster-futa-mom!!!

Strangely he calmed little and he begin to admire how big his mom truly is. Earlier he saw mom's flaccid 20 inch futa-penis and grapefruit sized testicles. She was right. Earlier when she said your 61 cm (2 ft) long cock is so small. Reason is that her testicles are now football sized and her penis at it's full height and glory. Mom's penis thicker than two 2 liter lemonade bottles and head of her penis is higher than her own head.

"Mom. How long is that monst....marvelous cock of yours?" John asks carefully.

"You almost call mommy's cock a MONSTER but as thanks for filling my pussy earlier I will ignore that and answer your question. This bad boy is 130 cm (4.3 ft) long."

Then John's monster-futa-mom gently smacked her monster cock with her palm. Her huge cock moved back and forward like elastic pillar. John thinks looks like the penis likes moms smacking.

John's jaw dropped "130 cm (4.3 ft) long......It is more than double my size!!!"

_"Yeah. That's right" _Mom said and John saw she is really proud of her longer and heftier cock.
