With his adrenaline high and his erection raging, Max hurried to the room his mother and aunt shared. Just like his sisters’ room, he opened the door slowly and slinked in. Standing at the foot of the queen sized bed Max saw the two women sound asleep, each facing toward the center of the bed. His dick pulsing with each beat of his heart, Max snapped loudly. No obvious change. Using both hands, Max snapped again. Again, no visible growth. The large blanket was making it hard to see, but Max didn’t plan on stopping any time soon. With both hands, Max began rhythmically snapping. Both woman let out moans in time with each snap. It took a bit but, in time, the blanket began to move. Each snap ballooned each MILF’s breasts larger and larger.
Feeling an uncomfortable tightness across her chest, Britney woke from her sleep. For some reason, her night gown was squeezing her chest way too much. She heard a noise, was it the ticking of a clock? Why was the tightness getting worse? She tried to sit up but found a heavy weight on her chest keeping her from fully sitting up. “Alison. Alison!” Britney called in a groggy panic.
“What?” Her sister answered.
“Can you turn on the light?” Britney pleaded, wanting to see what was holding her to the bed and squeezing her.
“Why?” Alison groan in annoyance. “What’s that noise?” She yawned.
“I don’t know, turn on the light,” she insisted.
“I…I can’t. I can’t turn over,” Alison voiced. “Why is my top so tight?” She asked.
“Mine is too. And…it keeps…getting…tighter,” Britney winced as, unbeknownst to her, her night gown was cutting deeper and deeper into her breasts. “OW! Something just bite me,” Britney yelped.
“I don’t think…” Alison began before another sharp pain pelted Britney’s boobs. “My top is bursting its buttons,” she announced.
“W-why…” it was then that a small series of popping noises silenced the pair as the middle seams of Britney’s night gown began to give. “What’s happening?
“I…I think my boobs are…” Alison couldn’t quite form the words. A volatile mix of panic, confusion, wonder, and arousal filled her as the snapping continued.
“T-that’s ridiculous. Our breasts can’t possibly be…” more ripping from her gown interrupted Britney’s denial.
Alison undid the buttons on her pajama top, freeing her growing globes as the top breast slipped down toward the foot of the bed to lay beside its twin. “They are, my tits are huge,” Alison gasped in disbelief as she grabbed a handful. “How big are they?” She wondered aloud.
“They’re their normal size, because out breasts aren’t…” Britney was again interrupted, this time by the two woman’s boobs meeting in the middle of the bed. “Growing,” she gasped, her ability to deny reality having finally been bested. “How is this happening?” She screamed panicked.
Max wasn’t worried about the scream. He knew that Alison had sound proofed her bedroom years ago after her husband died. She didn’t want her daughters listening in on her late night escapades with her gentlemen callers.
“I have no idea, but… it’s it kind of hot?” Alison offered, her arousal having skyrocketed.
“No, no it’s not. It’s OH!!!” Britney moaned as Alison grabbed a meaty hand full of her sister’s tit flesh.
“Look at these honkers. They’re the biggest boobs I’ve ever seen. Ooh, and we keep getting bigger,” Alison moaned as she kneaded both her and her sister’s boob.
“A-alison, y-you know my, my breasts are ah,” Britney gasped.
“Hmm, yeah they are. Are they getting more sensitive are they get bigger?”
“N-n-no. Maybe?” Britney wasn’t sure. She didn’t have a clue what was going on anymore. Then, out of nowhere, it stopped. “T-the sound. It’s gone,” Britney acknowledged.
“Does…does that mean…” Alison was disappointed by the sudden stopping of her growth. Letting go of her sister’s boob. She did her best to feel around her own tit in the darkness to try and get an idea of how big it was. “Feels like a beachball filled with jello,” she mussed.
“Whatever,” Britney blushed, trying not to think about the size of her mammaries. “Can you reach a light or your phone,” she asked reaching behind herself in an attempt to reach her own.
After a grunt of effort Alison respawned with, “no.”
“Huph, let’s at least try and roll onto our stomachs. These boobs are getting uncomfortable in this position,” Britney instructed. Both woman threw their legs off the sides of the bed pulling their breasts apart from the center. “How did this happen?” She sighed. Suddenly, the light turned on. In shock both woman looked around. “Max?” She said in shock and confusion.
Now able to see, Max figured both woman’s boobs were about 20 inches in diameter, or the size of a beach ball. Before either woman could say anything else, Max took a deep breath in before snapping rapidly using both hands. “OH!!!” Alison screamed in surprise and joy as their growth continued.
“Max!? Y-you’re doing this? How, why?” Britney questioned as her boobs rippled from the speed of their growth. After her son refused to answer her, Britney ordered “Maxwell, stop this immediately!”
“Don’t you dare. Keep snapping sweetie,” Alison contradicted.
“What’s wrong with you. This isn’t right or practical. We’re literally pinned to the bed by our breasts. How are we going to live like this?” Britney questioned.
“Max’ll take care of us. Won’t you sweetie? Keep going. Auntie Alison wants to keep growing,” she moaned as she rubbed herself.
“A-are you masterbating? ALISON FOCUS!!! We’re getting too big!” Britney shouted as their breasts once again collided, each beginning to resemble bean bag chairs.
“No! We’re not nearly big enough!” Alison argued as the bed began to groan from the growing weight.
“M-Max, your hear that right? You hear the bed is giving out? D-don’t you think you’ve made us big enough?” Britney asked, her voice beginning to tremble. He didn’t respond, he just kept snapping.
“That’s right, keep snapping sweetie. Don’t stop till the bed gives out. Hell, make us burst through the house!” Alison screamed in euphoria.
“NO!!! Max please stop this!” Britney begged. The bed groaned more and more as the growth continued, their combined size covering the entire mattress and beginning to overflow it. Finally after a valiant struggle, the bed frame finally surrendered and both women crashed to the ground. Max stopped snapping, mostly from shock as the four monstrous orbs of flesh violently jiggled from the fall.
All three of them were gasping for air. Max’s forearms burned from the prolonged effort, but it was totally worth it. His mom and aunt were absolutely, huge.
“That…that felt good,” Britney confessed as her face flushed red and her hand drifted toward her crotch.
“Well sweetie?” Alison said looking at Max expectingly.
