The Agate story idea received the most votes, so it'll be getting a third chapter now, making it only the second story idea to do so (the first being Futa-Frisk).
Holly Blue Agate had lost count of how long she'd been in the room with the humans. The earth quartzes seemed to think watching her be fucked by humans was even hotter than fucking her themselves. Agate couldn't understand it, couldn't understand why she resisted it so little these days. Maybe it was just because she knew by this point that she had no chance of stopping it, and so there was no point in wasting the energy.
Or maybe, she feared, she was starting to enjoy it. Regardless of whether or not she was, she was currently tied to a tree, her arms behind her back, her mouth held open by a ring cock, and her legs tied to remain apart at all times. She'd been forced to shapeshift a cock that was also tied to prevent her from cumming from it, and had gone two full days without release. AT this rate, the quartzes really were going to break her mind.
The human woke, and the sex began again like it had the passed few..weeks? Months? She couldn't tell anymore. A blonde female human dropped onto her tied cock, bouncing up and down on it to take the entire length. The quartzes had told the humans a whole list of things that Agate loved, and they were now determined to fulfill them every day; despite the fact that none of them were kinks of Holly Blue Agate.
The humans had been told that Agate loved being teased and denied climax for days, even weeks, that she loved having every hole stretched to breaking point by taking as any cocks inside at once as possible, that she loved eating out the asses of males and females alike, and that she loved having her body tortured and punished as painfully as possible.
As the female rode her swollen cock, two males got beneath her, both penetrating her ass at once while two others fucked her pussy. Two more hilted themselves in her mouth and throat while a fucking futa squeezed Agate's tits around her cock. The humans, having been bred and trained perfectly thanks to the automated process of the zoo, had better sexual stamina than any normal humans could have. Even the weakest of them could last hour after hour, cumming at least ten times before they felt the least bit winded.
After pumping Agate full of more cum that her body could handle, all of it much thicker than gem cum, they pulled out of her and off of her cock, beginning to punish her body; striking her legs, chest, and pussy with paddles and whips. They struck her desperate, twitching cock with a flog, slapped it, kicked it. Agate got no respite, her body writhing in the blissfully agony for hours; the gems taking up the torture after the humans tired off it.
"You wanna cum real bad don't you?" Carnelian questioned her. Agate nodded immediately, whimpering as Carnelian dropped down onto her cock, beginning to ride it with her ass; the tightest hole in the entire zoo. "You sure you wanna cum so soon?" She asked, dropping her hips as painfully hard as she could, "It's only been three days. Imagine how it'd feel to have your cock trapped and bound and desperate for a whole week~"
Agate shook her head, begging against the gag. Carnelian ignored her, riding her cock harder and harder throughout the night, making her feel ever orgasm she went through and letting her experience no release. The gems were sure that when they finally did let Agate cum after this, she'd be completely broken, and they wanted to enjoy her struggling for awhile longer. They'd let her cum at the end of the week...maybe...
