Hoping I find a partner who's into this shit half as much as I am. I don't even know how you break it to your partner that you'd get hard if they were hugely pregnant. Or if their boobs started growing. Or if they just grew into a giant. Fuck. Im wierd
I apologise, I hadn't seen you didn't do that, tho still I'd really like this prompt, but of course changed to be in your comfort zone! cos it's a favourite of mine! Sorry again!
4, c (breast expansion right?) f(ass), f (muscle) 1, f(cock)
Abby experiences breast, ass, and muscle expansion while Isaac experiences cock expansion.
(huh, there's no setting... I'll just get creative)
Abby and Isaac awoke on opposite sides of a featureless metal room. There were no sharp corners: the walls, floor, and ceiling met with rounded chamfers. The two were both naked. Isaac let out a yelp and covered his crotch, and averted his eyes from Abby. Abby was more preoccupied with trying to find a door to the room.
From the ceiling, a cylinder lowered with recesses on it containing all sorts of antennae. Abby and Isaac both froze and stared at it. It released a few pulses of light, some buzzes, and then retracted. The two stayed staring at the ceiling returned to a seamless, flat surface.
"Where-" Isaac started to ask, but was interrupted every surface in the room began to glow. The two moved next to each other in the center of the room, fear pushing them together. Just as suddenly as the lights stopped, they receded back to the previous low light level.
"Hello?" Abby called out, assuming they were being observed. "We wo~ould .... Oh~" Abby started, but failed to finish her sentence as a myriad of pleasant feelings washed over her body. Quickly, her lithe body took on tone, becoming muscular, she stretched and flexed, feeling the burn of a good workout. Then, she moaned loudly as her breasts began to grow, a smile spreading across her face as the small nubs rapidly ripened to about the size of her head. She almost fell over as her ass started to grow, with her hips and thighs adjusting their own sizes to accommodate.
Isaac stood apart from the dazed woman, enraptured by her growth, and suddenly let out his own moan. He looked down and took his cock into his hand, then both hands: it was rapidly growing larger! He came as it surpassed eighteen inches, a large jet of precum pouring out before several thick ropes of cum shot across the floor.
"I think they want us to fuck." Abby said, eyes glued to his cock as she steadied herself.
"Yea!" Isaac agreed, "Do you want to?"
"Yes!" Abby replied, taking his cock up, wrapping her tits around the shaft, and taking the tip into her mouth. "Let's put these new bodies to go use!"
