The bag made a creaking groaning sound and the cum pouring from around her dick tripled in quantity spraying back along her length as the enchantment started to unravel. A constant booming explosion of cum, a backblast of white that coated the centaur's back legs in a thick heavy layer and out between, spraying out meters and meters behind her, leaving a river of cum in her tottering trotting steps that caused the other people in the caravan to cry out in surprise as a wash of white inches high flowed over their feet, the bofos making bird like caws of alarm.
Fey groaned as the high pressure fluid massively stimulated her cock, massaging her turgid balls, rolling down her length, fighting to enter her urethra that continued to force more and more cum into the bag, the violent rough stimulation pushing her to ever-higher heights of pleasure in a positive feedback loop.
Kayla scrambled to the back of Fey to see the sheer amount of cum blowing out in a huge stream behind her.
"She's gonna break the bag! We- we need to get it off before it explodes!"
"I've got it!" cried Ellaria.
The elf slipped from Fey's desperate grasp and ducked down between her front legs where she found the bag, bouncing around on Fey's rigid cum coated length. She could see the seams of the bag breaking apart before her very eyes.
How many times had Fey cum inside the bag over the last few days? A dozen times? More? It would be bad if it broke, very bad, maybe even dangerous. All this passed through Ellaria's mind in a moment.
Without hesitation, she reached out and grabbed hold of it and with a grimace set her feet and heaved backwards.
With a shriek from Fey the bag ripped free, stopping the stream, and Ellaria was left holding it while facing the cum-coated length of Fey's dick. She only had a moments glance before a thick rope of cum exploded from Fey's urethra and slapped across her face and chest. She stumbled backwards in surprise as more and more heavy ropes of cum struck her with shocking force until she lost her footing on the cummy ground and fell over, the bag coming with her.
She hit the dirt hard, and the bag came down atop her chest, slapping down against her breasts, and because the bag was still open the motion and the impact combined together to abruptly dump a small lakes worth of cum over the elf, exploding from the bags opening like a full on geyser.
"Oh no! Ella!" cried out Fey as the elf vanished in a blizzard of white before her very eyes.
Fey dove forward, her cock still spraying long ropes at such high velocity that the straight lines of white barely arced through the air.
She awkwardly dropped to her knees, desperately ignoring her spasming body, and reached out for the elf who was layered in white inches thick. She clawed with her hands heaving away layers of her own cum, unburying the elf beneath until Ellaria responded, sitting up suddenly, a sloppy white moving mass. The elf coughed and spluttered beneath her heavy frosting, clumsily wiping at her mouth, desperately clearing her throat until at last she managed to heave a free breath.
The ridiculously gorgeous elf looked around, a little frazzled from being so overwhelmed with cum. She looked at Fey, then looked down at herself, then she licked her lips, tasting Fey.
"Uhm. I saved the bag," mumbled the elf holding up a white blob.
"That's okay Ella," said Fey looking at the thing that was probably the bag in Ellaria's hands. "At least it didn't fully break."
"How do you know?"
"Because we're not literally swimming in my stuff right now. I uh, might have gone a little overboard these last few days, my uhm, balls have slowly been getting bigger and bigger no matter how much I cum and I didn't know what else to do..."
"They are?" Said Ellaria, her voice a little shocked, there was a hint of interest there too. She licked her lips again and Fey couldn't help but notice the elf surreptitiously take some of herself into her mouth.
"Y-yes Ella, we might need to find another lady of the night when we get to the city."
Ellaria's eyes were laser-focused on Fey's hindquarters.
"Y-yeah, someone else, an expert, t-totally what we should do, once we get to Bine, yes."
The elf swallowed distractedly, eating that small part of Fey that she had taken into her mouth.
"What on earth have you done to my Dimensional Bag?" said a voice.
Fey turned to find Rina. The lamia was, large, very large, her belly a huge thing that she rested atop of. The strange thing was that she was also floating, her tail drooping over her massive smooth stomach to drag along the ground behind her as she hovered.
