It was Scootaloo's twentieth birthday and Rainbow Dash had a special present for her. She had wanted to do it for her eighteenth, but other plans came up, ditto for her nineteenth. Luckily it was still just as good a present two years late.
This year the celebration was with Rainbow's family in Cloudsdale. Rainbow's parents had been as happy as she was to take Scootaloo in as an honorary sister. There was cake and games, in accordance with Pinkie Pie's wisdom you never were too old for those. And then, the surprise.
Rainbow gave Scootaloo a blindfold which she dutifully put on. But she wasn't led anywhere in the house. Instead, she felt Rainbow pick her up and fly off with her. She asked where they were going but of course Rainbow didn't answer. It was a surprise after all. They flew quite a ways, leaving the whole neighborhood behind. Scootaloo's excitement grew, just what the hay had Rainbow gotten her that needed all this?
Eventually Rainbow landed. She didn't unblind Scootaloo though, just slung her over her back as she trotted into some building. There were some sounds from far off, but nopony seemed to be near them. They went through a door and into a room that was a little bit warmer and a lot more humid. Rainbow set Scootaloo down but stopped her from reaching for the blindfold.
"Not yet. Just a little bit longer, I promise."
Something liquid dripped all down her back, from her withers to her rump. This was followed by Rainbow's hooves rubbing what proved to be oil into her fur all across her body. Scootaloo was confused, she didn't think Rainbow would go to all this effort for a massage. Even her underside got coated. Even under her tail. Scootaloo gasped as there was a sudden poke from Rainbow using a squeeze bottle to fill her asshole with the slippery liquid. "R-Rainbow?" Scootaloo could feel her pulse rising, her dock trembled too.
"Come on in now," Rainbow said, but she wasn't talking to Scootaloo. There was the sound of many ponies shuffling into the room.
The blindfold was pulled away and Scootaloo saw that she was in the Wonderbolt's locker room, surrounded by said Wonderbolts. Scootaloo felt very warm all of a sudden.
Soarin sauntered forward from the group. He was wearing his flightsuit halfway unzipped, leaving a big patch of chest fur open, narrowing as it curved under him. "I hear it's a lucky mare's birthday today," he said, smiling.
Scootaloo had met him and the other Wonderbolts before. That was a perk of being Dash's "little sister." But she'd always looked at them as her heroes, or Dash's friends. Now she was very suddenly very aware that they were a bunch of studs. Strong hunky stallions. A pang of nervousness shot through her. She'd been in threesomes before, but never anything like this. The fact that it would be a challenge was part of Rainbow's gift.
"You ready to come and unwrap your present?" Soarin said, gesturing to his zipper.
The cheesy porn line cut through her hesitation. She laughed and ducked under him. She grabbed his zipper in her teeth. He wasn't sweaty, but he'd had the suit on long enough to trap a hearty dose of musk. She was horny enough not to need the scent to drive her wild, but it sure didn't hurt. Her tail was flagging high and she thought it was too bad nopony could see from the angle she was at. She encountered a bump, and revealed the tip of his cock. As she uncovered the shaft she felt his length droop down across the top of her head. She reached the end of the zipper and Soarin finished the job of shaking the suit off. Meanwhile she was pressing her face into his balls, giving them a good lick. She liked balls.
He stepped away and trotted a circle around her, eyeing her up. It was the nice kind of ogling, the kind that was from a guy she'd already decided to fuck. She turned to give the rest of the crowd a good view of her glistening, needy rump. She was fully in the mood now.
That was good because instead of mounting her Soarin suddenly bowled her over onto her side. The soft cloud of the floor whumphed into her. He knelt and positioned the tip of his cock at her pussy and laid down so he was fucking her belly to belly. Leave it to a Wonderbolt to put some unusual moves on her. He finished maneuvering by grabbing her and rolling onto his back.
She was on top now but she sure wasn't in control. His cock was goood and he pumped it into her in a way that none of the guys in Ponyville could match. The thought that he had probably plowed Rainbow Dash the same way added a nice glow to her feelings.
It soon became apparent why Soarin had taken this position. More stallions stepped forward reminding her that they were not just there to watch. Two of them—Fire and Lightning Streak, though Scootaloo could never remember which was which—stood at either end. She turned her head to look back as the orange and cream stallion behind her mounted her the usual way, shoving himself into her asshole as he did. His brother in the front put a hoof on her chin pulling her to face forward. She opened her mouth wide to let his penis in.
Scootaloo's little wings fluttered. She'd been taken from both ends before, but never had all three holes filled. Heck, she'd never even had her pussy and ass stuffed at the same time. She felt the cocks back there rubbing against each other, each trying to stretch it's respective hole out. She would have moaned if her mouth had been empty. But it wasn't and instead inch after inch of warm, slight salty horsecock slid into her mouth. Sweetie Belle was the throat queen but Scoots could put up a decent effort herself. She made it down to the medial ring before she gagged for air.
She felt hollowed out, more penis than pony. She squirmed and writhed her body in the middle of these three stallions, not trying to escape, but because she wanted to throw her body into it and that was as much as she could move. The temperature was incredible between her own internal arousal and the three bodies around her. She wanted more heat. She had cock fever.
Soarin had gone first and now he came first. She felt that unmistakable flare and pulse as he began to fill her womb with seed. The air picked up the distinct smell of semen as drops of it began to spill out of her. The scent granted her wish of inflaming her horniness further. "You're doing great, kiddo," he whispered in her ear. He gave that ear a little nip of appreciation.
But Scootaloo was not in a place to be thankful. She was thinking more about who was going to take Soarin's sloppy seconds. She couldn't see who else was around her, as her face was currently wedged into the base of Fire Streak's cock. It was a moment of respite for her to take a few ragged, musky breaths.
He pulled away to let Soarin out from under her. Then he took his place. As he was positioning himself Scootaloo felt a glob of cum drip out of her and down onto him. He didn't say anything. He did nothing to stop up the leak either. Instead of refilling her cunt he placed his tip on the rim of her asshole, alongside his brother's shaft.
"Oh shit. I don't know if my hole can handle that."
"You can do it!" Rainbow yelled.
Fire nodded. "Don't worry, we'll go slow."
Lightning pulled out with a pop. Then together, with practiced coordination, the two stallions pressed into her open butthole. Scootaloo bit her lip as the stretch rapidly increased to the limit of what she'd ever taken up the backdoor, and then some. But true to their word, they were gentle—at least as gentle as shoving multiple cocks into the same hole can be. Soon lip-biting wasn't enough. Scootaloo screamed a long string of "Fuck!"s.
A cheer went up from the ponies around her as the dicks slowly slid into her straining sphincter. It was uncomfortable, but Scootaloo embraced that. It was the thrill of pushing herself to new limits. Even though it was too tight a fit to really fuck, she was close to cumming from sheer excitement. She craned her head back to see what was happening to her butt. When she faced forward again, she locked eyes with Rainbow Dash who was beaming at her with pride. That was enough to push her over the edge. Her muscles trembled, her tongue lolled out. She wasn't much of a squirter, but this was enough to get a nice spurt out of her.
Sweetie Belle always said that you knew it was a good gangbang when you lost track of what was going on. Scootaloo trusted her on that topic. By that standard this was a great time. There were more guys, Wonderbolts Scootaloo didn't know as well, there were stallions who kept their flightsuits on, only leaving their dicks out. There was at least one pussy that shoved itself in her face. There was a lot.
Eventually everypony had had enough. Scootaloo was exhausted, sweaty, covered in what felt like gallons of cum. She couldn't see a thing for all the goo on her face. Her body was sore as fuck and could hardly stand. Somepony leaned against her side and led her to a bench. She felt multiple towels get thrown over her. She didn't even have the strength to wipe her own face off so the other pony did it for her. It took quite a bit of cleaning, but eventually she could open her eyes and see it was Rainbow Dash taking care of her.
"You did great. Those guys sure know how to take you for a ride huh?"
"Mmmhmm." Scootaloo's ravaged throat couldn't make words, but she nuzzled up against Rainbow Dash to show her thanks.
"Happy birthday, Scoots." Rainbow draped a wing over her sticky body. "You think you can make it to the showers?"
Scootaloo shook her head.
"Alright. Take as long as you need."
