For Button Mash, birthdays meant eating lots of cake, opening lots of new games and drinking massive amounts of soda. That, unsurprisingly, meant several trips to the bathroom throughout the day.

Towards the end of his birthday party, after the cake had been eaten and the games opened and the massive amounts of soda consumed, Button made one final trip to the bathroom. He was ashamed to not be there to see the guests out (especially Sweetie Belle), but sometimes biological necessities outweighed common courtesy.

As he was wiping himself off after finishing his number one, the door handle rattled ominously. Button looked at the door, his eyes widening when he realized he'd forgotten to lock it. He jumped off the toilet, his junk slapping the seat, but the door blew open before he could cross the bathroom to lock it.

A gray and yellow blur sailed through the doorway, striking Button and knocking them both to the ground in a brown and grey pile of limbs, feathers and propeller hats. After a moment, Button disentangled himself from the blond-maned gray pegasus and got to his hooves. "D-Derpy?"

Derpy rolled over onto her belly, only one of her eyes focusing on the colt in front of her. "I'm sorry, Button. I just don't know what went wrong." Tears formed in her eyes. "I hope I didn't ruin your birthday! I can't ruin another one. Not after the Incident."

"Not at all! I had a great—"

"I knew it!" Derpy wept. "Please, please, is there any way I can make it up to you?"

Button normally hated to take advantage of ponies. However, this time, he spotted a new kind of opportunity his hardening colthood just would not let him refuse. "W-well, there is one thing you could do." He sat down on the tile floor with his hind legs parted to present his colthood.

Derpy wiped the tears from her eyes and smiled. "Oh! I can do that!" She scooched herself forward, bringing her face closer to the penis in front of her. "The ponies at the post office keep saying I'm just good for popping out foals."

"I don't think they meant that in a goo—ahh!" Button faltered as Derpy dropped her head and took his entire colthood into her mouth at once, her tongue swirling around his meager length. There was a slight tang of urine on it, but it soon dissipated.

The feeling of Derpy's mouth on his cock was absolutely indescribable to Button. He'd never felt anything as amazing as the warm wetness currently engulfing his colthood, even when he was playing Return to Castle Pferdenstein. In what seemed like no time at all, Button felt something start to happen, like a tightening sensation behind his colthood, and a swelling at the end of his cock. "Derpy! Wait!" he cried. "Something's coming!"

Derpy pulled off of him completely, planting a kiss on his glans before bringing her head up to look at him. "Did that feel good?"

"Holy Celestia, that was amazing!"

The pegasus frowned, her eyes downcast. "I just don't know what went wrong."

"What are you talking about? That felt—whoa-ho!"

Derpy took him into her mouth again with a determined expression on her face. She sucked harder and swirled her tongue faster around his length. She tilted her head this way and that and occasionally stuck out her tongue to lap at his developing balls. The tightness soon came back to Button. He groaned, his body going rigid as the end of his cock flared wide until, with an explosion of sensation, he felt something run up his length and fire out of the end. On instinct, Button reached out and grabbed the back of Derpy's head in his hooves, forcing her into his crotch.

"Glrk! Mmf!" Derpy's eyes went wide and she began to cough as the tip of Button's cock hit the back of her throat. White liquid shot out from between her lips, getting all over the tile and Button's crotch. Button only bucked his hips forward, shoving himself even deeper into Derpy's muzzle. "Ngkk! Gakk!" Derpy kept choking as the colt roughly spent his first load in her throat.

When Button released his hooves, Derpy tore her head away just in time for one last squirt to rail over her face. She sat up, coughing and panting with white-stained drool hanging from her lips. A blissed-out Button Mash fell on his back, his softening colthood laying across his belly, glistening with Derpy's saliva. His tongue lolled out of his mouth and his eyes were unfocused. All he could think about was how awesome Derpy had made him feel. It was nearly as good as when he'd more than doubled the Pac-Pone high score at the diner, and far messier in a way any colt would appreciate.

When she'd finally managed to catch her breath and wipe the spit and white stuff off her face with some toilet paper, Derpy turned her attention to Button Mash. "Oh no! I just made things worse!" She jumped to her hooves and rushed over to Button. "I should've known this would happen," she muttered, fixing her good eye on the barely-conscious colt before her.

"Mooore," Button moaned out, almost unaware of his own voice.

"More?" Derpy thought for a moment, her one eye rolling upward. An idea occurred to her. "Maybe… maybe I can come back tomorrow?" she suggested. "I have to take Dinky home, but I promise I'll make up for—*sigh*—for ruining your special day."

Derpy waited a moment, but Button still wasn't quite in a responsive state, further driving her to despair. Crestfallen, she stood up again, opened the bathroom door and left, her wings dragging on the ground. "Dinky!" she called. "It's time to go!"

Button was just about able to make out a disappointed, high-pitched "Aww" from somewhere outside the bathroom. All he could think about, though, was getting Derpy to do that to him again. And again. And again.
