"I want you to fill up my balls, Mom, " Kim said simply. She realized how much she loved having her juicy balls stuffed to the brim, and filling them with the amount of cum in her mother's monstrous jizz tanks would effectively double their size, not to mention it would feel incredible.
"Ohh, I was hoping you'd say that," said Hannah, feeling up her daughter's massive testicles. She gave Kim a kiss on the lips, then a kiss on the dick, before stepping back so she could properly fuck Kim's urethra. Her dick was smaller than Alice's, so it slid into the stretched hole with ease. Hannah and Kim moaned at the sensation.
"Oh, Kim, this feels wonderful!" Hannah exclaimed. "Why have we never done this before?" She thrusted in and out, her huge balls swinging back and forth every time, stirring up their creamy contents.
Meanwhile, Becky had convinced Alice to give her a blowjob, since she hadn't gotten in on many of the activities so far. You got to watch from atop her soft breasts. You never realized what a pro your little sister was at giving blowjobs until now, and you were beginning to wish you were normal size so you could experience it yourself.
Alice slobbered all over Becky's fat cock, at times swallowing the whole 10" like a pro. She licked it all over, even moving down to her hairy balls and and tight anus. Becky moaned and cussed in pleasure the whole way. Your dick couldn't have been harder right now.
Back to Hannah and Kim, things were heating up. "You ready for Mommy's big cum load in your nuts, honey?" Hannah purred as she fucked Kim's dick. "You want Mommy to make your balls the biggest ever? Because Mommy wants to; she wants to shoot all her yummy cum right into those beautiful balls of yours, to make her sexy daughter happy. You want that, hmm?"
"Yes, Mommy, I want all your cum in me," Kim moaned, lost in pleasure. "I wanna have the biggest balls ever."
"Oh, you will, sweetie, trust me..." Kim's dick was drooling precum profusely, lubricating the way for her mother. Kim was about to explode with anticipation; Alice's load going into her balls had been heavenly, but how would Hannah's much larger load feel? She had to know. She tightened her urethra around Hannah's cock, increasing the pleasure so she could cum sooner.
"Oh, ohhh, here it comes, Kim! Mommy's gonna cum in your balls!" A few more thrusts, and Hannah's huge balls pulled up to her crotch, expelling their gooey contents right into Kim's dick. Both girls moaned loudly at the sensation.
Kim could clearly feel it; each spurt of her mother's orgasm lasted several seconds, and her sperm had a consistency close to pudding. All of Hannah's cock milk poured into Kim's already huge balls, engorging them further. She could barely stand up.
When Becky looked over at the scene Kim and Hannah were causing, she couldn't hold her load anymore, and suddenly blew her load into Alice's mouth without warning. Alice was taken by surprise, but Becky instinctively held her head down, forcing her to swallow her thick load until her luscious balls were completely empty. Alice, however, took it in stride; she'd learned to handle surprise cumshots from all the years she'd spent sucking off Kim, who loved to see how she reacted when she didn't warn her. She loved the taste of cum anyway.
Hannah's orgasm seemed like it would never end. What must have been a gallon of sperm blasted into Kim's ballsack over two minutes. She couldn't even describe the feeling. She had so much cum in her balls that she could actually hear it sloshing and splashing around inside of them as Hannah's was added to it.
Finally, it ended. Hannah pulled out and grinned at her daughter, satisfied with the sex, and the results. Kim collapsed on her back on the bed, her newly filled balls dangling down between her knees, close in size to watermelons now.
"Now that was fucking," said Hannah, wiping up some of Kim's sweet pre off her dick and eating it. "We need to do that more often. A lot more often."
"Yeah, okay, sure..." panted Kim, still reeling from the sensation. "I'm just gonna... gonna lay her for a bit. That was, uhh... yeah, that was really good."
"And it definitely worked out," Hannah continued. "Look how big your balls are now! God, they're so fucking huge!" The horny mother kissed and caressed her daughter's enormous testicles, in love with their size. "I wish I was Will's size; I'd craw right in there and stay there forever."
"So, what are you gonna do now that you have all this cum inside you?" asked Alice, who had just had her head freed from Becky's dick.
"I don't know," said Kim, sitting up and pulling her balls onto the bed with her. They were smooth and warm; she almost wanted to hug them.
"What if we sent will into them in place of your mom?" Becky suggested.
"What, and let me drown?!" you asked, shocked she'd suggest that.
"You'd be fine; you survived before."
"Yeah, when it wasn't an ocean in there!" You absolutely did not want to take another trip into Kim's nuts, or anyone's, for that matter.
"Or, Kim could put all that cum to good use," said Alice, removing her tongue from Becky's asshole for a moment. She could probably bukakke all three of us plus Will!"
Kim's making all the decisions lately. What does she choose this time?
