Rainbow Dash was furious, how could her team do this to her? She was supposed to be training with the rest of the Wonderbolts, practicing routines that would amaze and astound. Instead, she was stuck working with the new recruits, participating in intense routines to burn off her excess weight. It was taking all her restraint to stop her from marching into Spitfire’s office, unzipping her suit, and slapped her monstrous cock down on the desk. At least then she could have laid her problem out for what it was worth and get this weight off her chest. Of course then she ran the risk of being kicked out of the Wonderbolts, or replaced for someone who was actually used to flying with a dick. No, the only pony that was going to be seeing Rainbow’s phallus would be the one responsible in the first place. Twilight Sparkle.

But until she could get out of the Academy and lose the weight she apparently needed to, Rainbow was stuck. Stuck like the thick dick tucked up against the underside of her Wonderbolt uniform. Her earlier orgasm had done enough to soften it up to hide, but she’d expected it to do something about the length as well. At around 16 inches long, with a hefty girth of six inches, it bulged rather obscenely against her stomach. Nobody had questioned it so far, but there was only a matter of time before she would need an excuse. Except there were none that came to mind. What was she to say? That she was smuggling a carpet from the Academy to her home? That she’d wedged a ream of paper under her suit because she’d ran out at home? The questions would only get more intense from there. Why not just buy some paper? Or a carpet for that matter? Rainbow Dash was a good liar, but even she hated open-ended lies. She was bound to trip herself up at some point and that would open up a whole other mess of problems.

She reclined on the bench she’d chosen to contemplate on, her uniform creaking as it struggled to contain her stallionhood. Watching the new recruits stumble over themselves as they tried to do the most basic of stretches, while funny, made her worry about how she’d look. Other stallions didn’t seem to have the trouble she was having, but judging by the bulges at the fronts of their suits, neither had quite the shaft she did. She expected there to be at least one, someone she could copy and observe, alas there was not. She took a deep breath, filling her nostrils with the bitter scent of her playtime, mixed with the freshly cut grass around her. If she was completely on her own then she’d need to make a few adjustments to her time at the Academy.

First, she needed a roomier outfit. Something just baggy enough that the bulge of her cock wouldn’t be so pronounced. Formally, she’d need to meet with Spitfire and request a new uniform and that would mean reasons for the request. More lies and Spitfire was someone who could easily see through a false story. So that was out. Though, it was the start of the week, which meant she could get into the laundry room and pick herself something appropriate. A perfect plan. She’d only need to be a few minutes, nobody would know she was even gone. She rose from the bench and sauntered off towards the Academy, the other recruits watching her as she went. They opened their mouths to call her back, but given that she hadn’t interacted with them all morning, they thought better of it.

Rainbow hunched over to give her suit a little more room. Her breasts hugged her dick with their smaller surface area to keep it from flopping forwards. She was grateful that they were no smaller than a C cup. If she’d been cursed with mosquito bites as well as a massive cock, she might have just given up there and then. When she passed one of her colleagues, she simply grunted and reached backwards, pretending that she was headed towards the local nurse. It wasn’t so much of a lie as it was taking advantage of the coincidence that saw the nurse and the laundry room sharing a corridor. Rainbow could exploit it all the way to her destination and then pass it off as nothing more than a fluke when people asked for updates.

By the time she reached the laundry room, her back was actually beginning to hurt from all the stooping. Perhaps she would actually need to visit the nurse after all. When the corridors of the Academy fell silent and the throngs of ponies thinned to one or two now and again, Rainbow seized her opportunity. She opened the door to the laundry room and slipping inside, putting the lock on before getting to work.

Inside the laundry room, she found that the pony in charge of this place, had left the spare outfits easy to identify. Rainbow Dash’s sat next to Spitfire’s and Soarin’s sat next to hers. Soarin was a big stallion, all that exercise had bulked him up considerably. She took one of his wonderbolt suits and held it up against her frame. It dwarfed Rainbow’s petite form, but it did have the space she needed. She spared a glance over her shoulder, the frosted window had no shadows outside, meaning the corridors were still quiet. She hung Soarin’s suit off the shelf and began to take off her own. Carefully, she unzipped the front of her suit, keeping the volume of the zipper whizzing to a minimum. She didn’t want to attract any undue attention. Nor did she want to catch the sensitive flesh of her cock in the zipper. She’d heard the sounds of pain and agony that had come from Soarin when he’d done such a thing. It did not sound pleasant at all.

Rainbow stepped out of her flight suit and pushed her feet into the leg openings of Soarin’s suit. Already it was a lot less snug that her suit, there was a thin layer of air between her legs and the material. This was what she wanted, what she needed. She hefted the top of the suit over her shoulders and adjusted her crotch. Each of her two balls fit snugly over their respective sides of the crotch. While her cock hung low and obscenely in front of her, bobbing as she bounced to fit the suit better, she did look good. Now it was time for the moment of truth. Cupping her flaccid length in both hands, she hefted the tube of flesh up against her stomach again. Using one hand to keep it in place and the other to zip up the suit. Once the tip was covered and Rainbow let go of her dick, she was delighted to see a reduction in bulging. No longer did it look like she was smuggling something in and out of the Academy. The bagginess of the suit meant that any curve of the bulge was distributed to the rest of the chest. It left her problem practically invisible unless one was already aware of its existence. Rainbow smiled and put her suit in her pile, before she slipped out of the room as stealthily as she arrived.

She made her way back to the practice fields, where the new recruits had opted to take a break. They shared a laugh with each other as they chowed down on healthy and fruity snacks. When Rainbow Dash finally joined them, the group collectively turned to stare at her before resuming their conversation. Rainbow snorted derisively. She didn’t need them. She was her own pony, she could have plenty of fun by herself. Her mind flashed back to the moment of fun she’d had behind the Academy. How her dick had stood proud, splattering her seed all over the wall, the ground and herself. Her heart skipped a beat as she realised she’d forgotten to make an effort to clean those stains from her suit. She blushed as her mind raced with questions that could come from the cleaner. Then quickly shoved those thoughts away as her mind began to wander to a scenario where the cleaner asked her what the stains were and Rainbow opted to show her.

She stood up, and walked further into the field picking a spot for her to begin with her routine. She’d show these new recruits what it meant to be a Wonderbolt. She visualised the target in her head. Nothing fancy, just a few high speed loops followed by some fancy turns to really show off what she was made of. She knelt low to the ground, resting on the balls of her feet. She looked up to the sky and pictured her path through the clouds, the way she would dip and duck through them. A smile spread across her face as she pushed off from the ground. She shot up into the sky like a bullet from a gun, leaving only a fading rainbow behind her. The recruits spared a glance her way, their mouths dropped open from the display. They were in awe of such skill, not to mention the blazing trail of colour she left behind. However their amazement was short lived as they began to notice the trail wobble ever so slightly. The rainbow of colour in the sky began to falter, losing its perfect shape as Rainbow Dash appeared to lose control.

Up in the clouds, Rainbow Dash cursed herself under her breath. She was used to flying without the extra weight her shaft and balls brought along. All her calculations about flights and tricks were useless to her. This showed in the way she failed to skillfully glide around the clouds. More than once she flew through a cloud, opening up the sky more than was scheduled for that day. Trying to correct her course and regain some of her composure proved to be difficult as well. With the wind zipping across her body, she felt a tingle down below. It was hardly the time or the place for this sort of thing. But as Rainbow felt a familiar swelling against her chest, she cursed under her breath. The scent of her arousal penetrated through the weaving of the suit, mixing with the cool air around her and penetrating her nostrils.

Down below, the recruits watched as Rainbow’s flying began to get a little more erratic. Her burgeoning shaft adding a little extra weight, dragging her down when she needed to be higher. To say nothing of the fact her mind was swimming with thoughts of dealing with her swelling erection. One of her arms reached towards her shaft and began to fondle it. The lack of streamlining with one arm extended forwards and the others bent an angle, sent Rainbow spirally off course. She slowed her wing speed and extended her arms once more to correct her course but it was too late. She spiralled ever further, picking up speed with each metre she dropped. Eventually she could no longer keep her arms outstretched, sending her tumbling faster. A group of trees looked like the desired landing place, it was either that or bounce across the solid ground. She crossed her arms to her chest and tucked in her legs, flapping her wings as fast she could to slow her descent. The ground rushed up to greet her, the leaves of the trees growing farther apart as she approached.

The recruits followed Rainbow across the sky, racing after her as she plunged into the canopy of a tree. They stood underneath the tree, expecting Rainbow Dash to fall out from the branches. When she didn’t, they immediately took to the skies to check if their estimates had been correct. After all, there were a couple of trees bunched together and she could have landed in any of them. Each of the recruits took a tree and began to look through the branches with a little more scrutiny. They were alerted to Rainbow’s presence when one of the recruits practically fainted into the arms of another. They all gathered at the scene of the incident and peered into the branches, where sure enough, Rainbow Dash laid sprawled out amid the foliage. The recruit had no doubt fainted due to the drooling, blue, phallus, pointing up towards the sun.

Rainbow Dash batted her eyelids, sunlight streaming in through the leaves. She didn’t register the recruits hovering around her, their eyes wide in shock as they stared at Rainbow’s throbbing manhood. Instead, Rainbow reached up and began to stroke herself. Then she heard the gasps coming from all around her and her eyes shot open. She saw them all gathered around her, she saw their expressions. The looks of disgust, of horror. She scrambled into action, pressing her shaft into her chest and trying to find the zipper. It was then that she realised the extent of the damage to her suit. The branches had clipped and torn the front of it to shreds. There was no way to hide her throbbing junk from prying eyes. If it softened somewhat she could stick it into the leg of her suit and fly away, but as it stood there she was defenseless. She had no choice. She needed to continue her actions.

Rainbow looked away and reached forwards to her dick, stroking it with shaking motions. The gasps returned once more, a few of the recruits leaving the scene, understanding the need for privacy. The rest watched on, documenting the events so that they could accurately report them to Spitfire. It would be quite the scandal to befall the Wonderbolts and would no doubt end in Rainbow’s removal from the team. Given the way she had reacted when she’d found out she’d be working with the recruits, it only seemed fair. For Rainbow however, the eyes watching her had something of a different effect. She felt a wave of pleasure wash over her, something far more powerful than she had experienced on her own. Each complete up and down motion of her hands sent pre splattering from her tip. It crashed against the leaves and twigs and on one occasion hitting a recruit in the foot. There came a cry of disgust but this just made Rainbow hotter under the collar. She bucked her hips and squeezed her cock tightly between her fingers. An eruption followed that was far more powerful than her first solo encounter.

Screeches of disgust rang out from the trees as the recruits were splattered with seed. Rainbow gave grunts and gasps as her warm cum rained down upon her. Splashing against the tears in her suit and matting her fur. The rest of the recruits scarpered, most heading off to wash their outfits clean, while the others went to report Rainbow. It would be their word against hers, of course, so Rainbow had a chance. Still, as she lay there, drips and drops of cum splattering against her from the leaves, she couldn’t think straight. Part of her wanted to explore her shaft further, but she couldn’t hang around. The moment one of those recruits explained their story to Spitfire they’d be hunting for Rainbow. She needed a place to lie low for a bit, and while she was nervous about her choice, it was her best bet.

She gave her wings a test flap, to her relief they weren’t broken. Carefully getting to her feet, twigs snapping underneath her. Balancing on some of the sturdier branches, she tucked her dick into what was left of her suit and took off. Her flying was still awful, the extra weight and the post orgasmic haze weren’t helping. Thankfully her destination was only a short way from the Academy. She blushed as she imagined the meeting she was about to make. Her parents had always supported her through everything, but now she was about to drop a bombshell on them. If they still cared as much for her after she revealed her newly acquired stallionhood to them, then they deserved some kind of medal.

Rainbow’s childhood home appeared on the horizon and she began her descent, crashing down right outside the door. She sprung to her feet and brushed off as much evidence of her playtime as she could and hefted the remains of her suit over her waist. She could already hear voices coming from inside, no doubt coming to see what had landed in their yard.

“It could be that Scootaloo filly, back to do another report on our daughter,” came the voice of her mother.

“We’ve really got to get her a better way of reaching us. I’m starting to get a little tired of covering over the holes she’s making.”

The door swung up open to reveal Rainbow’s parents, looking down towards the floor, expecting to see Scootaloo. Instead their eyes landed on Rainbow’s thighs and the bulge contained between them. They then trailed up together, darting across the stained patches of fur through the ruined suit, before making eye contact with their daughter. Her face retained the same cocky composure that it always had, except now the cracks were beginning to show. Her face faltered periodically as the real emotions she felt began to bleed through. Both parents showed sympathy, at least at first. Bow’s eyes soon descended again to the bulge in the leg of Rainbow’s suit. That had never been there before and his eyes went wide as he saw just how far down her thighs it extended. While Windy focused on the messed suit and the stains, wondering if Rainbow had been subject to an assault.

“Can…can I come in?” Rainbow asked, her voice shaking ever so slightly.

Both parents brought their eyes back up to Rainbow’s face, giving their reply in sync. “Of course, sweetie.”

The pair stood either side of the door and allowed Rainbow inside. They watched as their daughter rushed upstairs to her bedroom. They didn’t chase after her, they knew that was never an acceptable choice with Rainbow Dash, well they did now. Before they’d have hounded her to support her but now they knew to give her a little space. When she was ready to talk, she’d come down and talk. They gave each other a shared look of confusion before going to sit and wait for their daughter.

Upstairs, Rainbow Dash rifled through her drawers to find the spare set of clothes she kept there. Ever since Rainbow’s parents had learned the error of their ways, Rainbow had stored some of her stuff at the family home. Namely clothes and things that she could use in a pinch at the Academy. However, it was the set of casual clothes that she required. Normally reserved for a quick change from Wonderbolt training before heading out to meet her friends. This time it was just a set of clothes like any other, meant to cover up her body and look good in the process. Rainbow slipped a goldenrod shirt over her upper body, slipping her lower body into a pair of sweatpants. There was no need for anything else, her chest wasn’t vast enough to need a bra and panties would only complicate things down below. She sighed as she looked in the mirror. A patch of moisture punctuated the head of her shaft, soaking the clean sweatpants. This was just something she was going to have to deal with now, wasn’t it? Given her luck so far, it wouldn’t surprise her if Twilight couldn’t fix it either. She sighed loudly and headed downstairs to confront her parents.

When she entered into the lounge, she felt a pang of sadness as the photos of her younger self looked back. That Rainbow Dash could fly perfectly, her speed unmatched. That Rainbow Dash didn’t have to deal with a massive stallion cock stuck to her crotch. She turned her head away from the photos of her past and instead focused on her parents, who in turn focused on the leaking bulge in her sweatpants.

“It’s a long story,” Rainbow sighed as she took a seat away from them. Her body sunk into the fabric, pushing her lower body upwards and by extension that grotesque bulge.

“We’ve got time,” Bow replied, his eyes fixated on Rainbow’s crotch.

“Yes, dear. Please, it seems to be troubling you, the least you can do is open up and let us help you.”

“Help? Help?!” Rainbow stopped herself short of exploding at her parents. “There’s…only one pony that can help me and she’s the one that got me into this mess.” She sighed again. “I shouldn’t blame Twilight, I was the one who asked her for the spell. I’m the one that ruined my chances at continuing with the Wonderbolts.”

Windy Whistles got up from her spot and sat on the arm of Rainbow’s chair, wrapping an arm around her. “The Wonderbolts? How can this affect you being in the Wonderbolts? They have stallions on the team, don’t they?”

“They do, yeah. But, all of them have been flying with a stallionhood since they were young. I’m not used to it. It’s throwing my flying off. It’s like, like someone’s stuck a rudder on me that I can’t control.” She winced as she remembered the crash into the tree and what followed. “It has a mind of its own. Just look at it.” She gestured down to show the patch of moisture steadily growing larger against her thigh.

Windy rubbed Rainbow’s shoulders supportively. “Just like your father,” she muttered.

Bow’s ears perked up as his wife made reference to him. “You’re not suggesting…”

“Rainbow, dear,” Windy began. “I understand what you’re going through. Why, when you father was young, he was embarassed for a similar reason. No matter the situation, he couldn’t control his lust, there was always a tent in his pants.”

Rainbow cocked her head to look at her mother, then at her father and then back again. “What has this got to do with me?”

Windy wet her lips and reached her other arm to stroke down against Rainbow’s thigh. “Well, when he met me, I helped him with his little problem. It turned out that all he needed was a little ‘action’. A session at the beginning of the day and one at the end and his problems disappeared.”

“Are you saying…?” Rainbow’s eyes went wide as she listened to her mother.

“Yes, Rainbow. We’re here to support you. We’ve always been here to do that. This little situation shouldn’t get in the way of your dreams of being a Wonderbolt. You agree with that, don’t you, Bow?”

Rainbow’s father looked at his wife. His cheeks flushed red with either a blush or pride. “Of course, dear. If it helps our daughter, we’ll do anything.”

Rainbow felt like she was on the verge of tears. Her parents were so supportive and she regretted all those times she’d avoided them even more. She leaned into her mother’s shoulders, putting her arm around her and hugging her tightly. It didn’t bother her that it was implied that she’d be sleeping with her parents. She was just grateful that they offered a possible solution to her problem. Sure, it wouldn’t reset her life back to how it had been before she grew a dick, but it was a start. Windy Whistles and Bow Hothoof got to their feet and made for the door. They shared a look between each other and then looked to their daughter. Their eyes looked to her and then gestured upstairs. Rainbow gave them a devious smirk as she rose to her feet. Her bulge began to snake further down her thigh, thoroughly exciting Bow as she led the pair upstairs.

Author's Note

The next chapter will be the incestuous futa blowout. I was gonna include it in this chapter but I wanted to try and keep my chapters relatively short and contained.

Please understand.
