The Tale of Bathspounge

It was a typical day in Equestria. In a small room atop a normal looking house sat a pale pegasus by name of Snowflake. He however, resented his given name and insisted that all refer to him as Bathspounge. Having recently survived lube-poisoning, he had decided to rethink his life and actually make a move toward his life-long love, Twilight Sparkle.
Speaking if the lavender mare, she was reading a book about sexually applicable spells, as she is expected to do in a clopfic. She was particularly intrigued by a spell that allowed a stallion's 'endowment' (meaning cock) to increase in size. Twilight was a bit of a size queen, her own cock reaching a delicious two feet and a half feet while hard. She just had to find a willing stallion, and she knew one who was into some pretty weird stuff. Just then, Bathspounge entered her library.

"Oh, hey Snow," Twilight eagerly called back to him.

"It's Bathspounge," he responds, passing of what would have normally enraged him as if it were nothing because he really wanted to fuck Twilight.

"Oh, sorry." She leaves her book to walk over to her guest. "So, Bathspounge," she says with far too much slut in her voice, "what brings you here?"

"To be honest, I am here to seduce you," he responds flatly.

Twilight's mind explodes in excitement, yet she tries to remain looking sexy, for Bathspounge's sake.

"Really?" Twi asks as she flutters her eyelashes at him, "and how do you plan on doing that?"

"Well, you seem to be either way drunker than a librarian has the right to be in the middle of the day, or as into this as I am. So lets just fuck, where will you have me?"

"Wow," Twi thought, "he is a sperglord. But a sexy sperglord."

"Um, well," Twi starts, "I have this spell I wanna try, but it could get kinda messy, so how about the bathroom?"

"Fine by me," he says before dashing up to her bathroom.

Twilight follows him, bringing the book with her. "Alright," she says as she places the book down next to the sink. Spounge, get over here," she calls to him as magic drips from her horn. Spounge quickly assembles himself behind her.

"Okay, this might tingle a bit," Twi cautions as she shoots a beam of magic into Spounge.
And tingle it does, he soon feels his cock involuntarily growing hard beneath him, as well as simply growing, soon surpassing his normal thirty inches as it increases in thickness and length, finally topping out at four feet long and one foot thick.

"Woah…" Bathspounge groans as he looks down as his monster, "radical."

"Yeah it is," Twilight says as she states at his huge penis, licking her lips as she images it buried in her. She jumps into her bathtub and turns on the shower, letting the water plaster her mane to her head. "Come and get it, big boy," she teases as she shakes her plot, emulating one of the whores in Spike's naughty videos.
Bathspounge makes short work of coming and getting it, leaping into Twi's shower and mounting her, ramming his cock into her positively sopping pussy.

Twi moaned as the cock pushed into her, a large bulge pushing up her chest. She reached down to start jerking her dick before remembering that she had removed it with magic earlier, just in case he wasn't into that.

Bathspounge was slightly sad she had removed her cock, yet he said nothing about it, just in case she wasn't into that. He rammed his hips forward farther, penetrating her well into her chest as his balls slapped against her tits, which were only slightly smaller.

"Oh FUCK yes!!! Make me your fucking cock-sleeve!" Twilight moans loudly, practically screaming as her eyes roll back in her head, her tongue hanging out as a latge drop of drool falls out, splashing onto the shower floor.

He grabs her around her waist, pivoting his hips rapidly, filling her tight cunt with cock, threatening to tear her as his artificially large cock slams into her.

Twilight hugs the bulge his cock forms against her chest, snuggling her face against his flare through the skin of her tummy like a baby wolf snuggling up against his mother who he hasn't realized was shot by a hunter.

Twilight cums for at least the 12th time, yet nopony knows for sure, her brain having lost all rationality somewhere between 4 and 5, the only thought running through her brain now is how unbelievably good she feels as Bathspounge's massive stallionhood ravishes her.
As her body constricts around his cock, Bathspounge finally cums, blasting Twilight's insides with gallon after gallon of cock-juice. Her distended womb is filled in mere seconds as she is forced to take his cum into her, her stomach growing rapidly as cum fills her, soon expanded so much that it presses against the walls on each side of the shower. Bathspounge pulls out and shoots one last rope of cum onto her ass before falling down atop his bloated slut.

"Wow… holy fuck…" he groans, almost laughing in his euphoria, "you're so big!"

Twilight blinks a few times, her upper mental facilities returning to her. "Bathspounge," she gurgles as she coughs up a little blood, staining the white tile of the bathroom crimson.

"Yeah?" he asks between pants as he rubs her swollen tummy.

"You did great," she says before passing out, blood leaking from her maw.

"Twi, you okay?" Bathspounge asks as he looks around to see her face. He sees the blood and fears the worse.

"Shit!"
