“I dunno, surprise me,” Rachel smirked.
“Pfft! Your funeral, Ray,” Samantha grinned evilly, “Transform or Dare?”
“Both.”
“Bold, bitch. Bold,” Samantha commended, “So for your transformation, your butt will only go concave when you’re riding Jennifer, and will be a fat bubble when you dismount. This, and everything else that comes with the concave ass thing, will be true for all bouncerbutts and their riders. Additionally, you will grow a second pair of arms that you have full control over and fit through the same sleeves as your first arms. Only the four of us here will know that anything is different. For your dare, I want you to pleasure yourself with your second arms as discretely as you can, but right here right now in public. You can’t stop until you cum, or if you’re caught, whichever comes first.”
“Oh, that first part’s kinda clever,” Rachel smiled, not noticing that she had four arms now, “Should have probably came up with that myse-GASP!” She quickly quieted herself as her third and fourth arms started pleasuring herself. It was everything she could do to keep from moaning too loudly, not to mention that Jennifer could feel it all too.
“N-no fair, Sam!” Jennifer choked, trying not to moan herself, “I feel everything she feels same as the other way around! Hoof! Ah... ahnnn...”
“Well she said ‘surprise me’ didn’t she?” Samantha chuckled, “That’d ought to do the trick!”

“Oh my pretty mare, you have no idea how far I can go,” the goth rider cooed in her bouncerbutt’s ear, “I can show you crazy things tonight if you like.” The pair giggled at the thought they had at the same time.
Rachel and Jennifer were meanwhile trying to keep everything together, praying that they didn’t get caught. Thankfully, Rachel was able to bring herself off without drawing too much attention to herself, but did end up making a mess all over her steed’s tailbone. Jennifer started taking deep breaths to calm herself down now that it was over.
“Well, I said surprise me,” Rachel admitted, “and I’m certainly surprised. Four arms is gonna be a lot to get used to, but maybe I could multitask better with these things.”
“There you go, upside to everything!” Samantha smiled knowingly, “I’m glad you found out the town curse is real. That thing was started by my family like a century or two ago and, well, I’m stoked to find out that it wasn’t another one of my great aunt’s wives tales.”
“H-hold on,” Rachel spluttered, “Your family came up with the curse?”
“Oh, that’s right,” Samantha chuckled, “I only told Chiffon about this. I’m secretly a...”
