Dawn fidgeted against the ropes that kept her securely bound as she felt yet another stranger climax fiercely inside her sex. This was the fifteenth time, and it was no less disgusting and traumatizing than the last. The other dragon she was tied to, apparently named Lyra, was also being violated, but she was far too exhausted at this point to react much at all.

Once the torrent of seed into her womb subsided, she glanced over at the culprit responsible with tear-soaked eyes. It was a Rat with his Coyote buddy who had both used their respective portal pussy to rape both girls simultaneously, and their satisfied expressions made it woefully apparent the complete lack of remorse they felt in doing so.

"Damn bro, I haven't cum that hard in age!" the Coyote said with a wistful sigh as he pulled the dripping portal device from his cum-smeared cock.

"Hah, yeah bro, this is some top-tier pussy. The rat said, mimicking his partner, but further bringing the device to his lips so he could lick at the overstimulated clit, causing Dawn to squeal and whine from the sensation.

They then pulled their pants up and put the portal pussies on the table next to the 'Free Use' sign; their loose cum coalescing with the two captive dragonesses fluids as it leaked out onto the table.

"We'll be back for another round later, so don't go anywhere ladies. Not that you can," the rat promised, laughing with his friend as they exited the room.

Dawn glanced over at the dragoness her legs and arms were bound to, and noticed her eyes were rolled back in her head from exhaustion, her cheeks flush from all the overstimulation she was being forced to endure. Lyra was unfortunately here a lot longer than her, gauging by what was said by their captors, and it was doubtless Dawn would end up just as she was before long. The white dragoness was already starting to feel the lingering effects from all the excessive orgasms she's had to endure up until now, causing most of her body to ache; which was further exacerbated by the excruciatingly tight binds they had restrained her with. It also didn't help that her gag was excessively large for her mouth, causing further aching to her jaw.

This was the extent of respite, as the door to the room opened once more, and two more strangers stepped in, this time a Cheetah and a Horse. They glanced between the two ladies momentarily before the Cheetah said, "Hot damn, what sexy bitches these two are, we hit the fucking jackpot coming to this party!"

The horse was equally as enthusiastic as he glanced at where the portal pussies were and walked up to them. "So how do they work?" He asked curiously.

"Man, I don't know. It has something to do with portals, I didn't really ask about the specifics," the Cheetah replied with a shrug. "All I was told was that it was exactly like fucking the real thing because you basically are."

The horse nodded and picked them both up. "Makes sense to me," He looked between the two of them, and after a moment of thought, he kept Lyra's for himself - much to Dawn's relief - and handed the other one to his friend. They both then proceeded to remove their pants and underwear.

The Cheetah, who was already rock hard as his underwear came down, eagerly licked his lips as he took Dawn's portal pussy in one hand and his bulging dick in the other. "First one to cum has to buy the next round of beers!"

"You're on!" The Horse replied as he and the Cheetah shoved their portal pussies firmly onto their stiff shafts.

Dawn tried desperately to plead with them, but they seemed oblivious to her plight. It wasn't until she felt the thrust of the Cheetah's girth penetrate her that she shuddered with agonizing pleasure; a reaction mirrored by the fellow dragoness tied against her. Fresh tears welled up in her eyes as she watched them thrust into their respective devices with insatiable lust, and started to wonder if anyone would actually show them even an ounce of sympathy, or if they were doomed to this cruel, unyielding fate for as long as their captors deemed fit.
