How Rainbow Dash got a Sibling

The skies over Cloudsdale were clear and sunny. The numerous pegasi who made their homes within this cloud city went about their day in a happy display. Flying about, enjoying the comforts of the soft clouds to walk and sleep upon. As well as the fulfilling duties of managing the weather across all of Equestria. Along the cloud streets, within the rows of cloud homes, a certain him, belonging to a certain married couple, was in their living room.

Bow Hothoof, the husband was sitting in his chair, reading the paper as his wife, Windy Whistles, was pacing back and forth. He was calm, or at least calmer than his wife, but held a subtle indication that there was something the two needed to discuss. Windy eventually huffed, stopping her pacing to look at her husband. He tried to ignore whatever she was saying to him, until she lost patience and tore the newspaper from his hands.

“Hey! Listen to me!” Windy snapped, only to calm down as she huffed again. “Bow, we’ve been married for a long time.”

“Happily married, I should add.” Bow replied, smiling up at his wife, thinking his charming smile would calm her. But it wasn’t, which only caused his expression to drop. “Look, Windy, we’ve been over this, why can’t we have another foal?”

“Why? I mean look at me!” Windy replied, posing for her husband. Her body was very alluring, even as she was hitting her forties, she had a body that made even mares in their late twenties envious. “I don’t think I could handle another foal.”

“Couldn’t handle it? What are you talking about?” Bow commented, pointing to his wife. “I mean, look at you.” His hands started from the chest and worked its way downward. “Perky, round tits, still capable of having milk. A wide pair of hips, easily able to bear a child. And not a scrap of fat along your belly, perfect to get round and be sexy as fuck; just like last time!”

“That’s not the point.” Windy commented, crossing her arms as she pouted at him. “I’m too old to have a foal, I’m not as spry as I used to be when we had Rainbow Dash.”

“What? No way! You’re the hottest mare in Cloudsdale. But Windy, let’s be reasonable.” Bow interjected, standing up. “So why shouldn’t we give our little girl a sibling?”

“Bow, look at you.” Windy commented, pointing to her husband’s body. “Firm, taut muscles that can lift heavy storm clouds. A flat, ripped belly that could break lightning on. And a cock that could easily impregnate any fertile mare around.” Before Bow could say anything else, she continued. “But you wouldn’t be the one who would have to actually carry the foal. Rubbing her belly she looked at him. “After Rainbow, which felt like a bolt of lighting was coming out of me, I’m not going through that again.”

“You can’t be serious?” Bow asked, only to see the look on Windy’s face. “Well, it’s not like we can find a surrogate. I ain’t sticking my dick in any mare but you!”

“Aww, Bow, that’s sweet.” Windy smiled, but remained firm in her stance. “But sweet talking won’t change anything.”

“Look, how about we sleep on it a little longer?” Bow suggested, getting up to try and tenderly rub his wife’s back. “I think we should give Rainbow a sibling. But I ain’t gonna force you to have a foal if you don’t wanna. But I just want you to keep thinking it over. Please? For me?”

“Ugh…fine…I can’t stay mad at you.” Windy replied, giving her husband a tender kiss. “But until then, no bedtime fun.” She reached down to grab at the bulge in his pants. “Think you can keep your own lightning bolt under control until then?”

“For you, anything.” Bow smiled, chuckling a little as he felt himself getting hard at her touch. “You always did know how to make a point.”

Roughly a week or so had passed since that conversation. Bow would occasionally try to bring it up again, but Windy would politely turn him down. The two of them were proud of their daughter, Rainbow Dash. Not only was she the Element of Loyalty, a Hero of Equestria, but was a Wonderbolt now. Her parents couldn’t be prouder of her, but she had moved out of the house many years ago, moving to a floating home in Ponyville. The house, once full of life, excitement, laughs, and happy memories, felt a little too big, and empty.

Bow figured what better way to fill the house with the same excitement, would be to have another foal. He didn’t believe Windy couldn’t have another foal, but given how it went when they had Rainbow, he did agree, giving birth didn’t look to be a pleasant experience. Regardless, he wanted to bring this joy into the house, and was willing to do whatever it took to make it possible. This commitment and determination seemed to pay off, as by the end of the week, he received a letter from his daughter.

He didn’t keep his thoughts hidden, not even from Rainbow. Sending letters to and from Cloudsdale and Ponyville, the mare seemed to have come up with a possible solution. It would take a few more days of waiting, but Rainbow suggested they speak with Zecora, the zebra apothecary in Ponyville. Because of the situation, the zebra was willing to come to them in Cloudsdale. Speaking with Windy about it, she agreed to a conversation, but had no idea what she could possibly do for them.

A few days later, Zecora arrived at their home. Her ability to walk on the clouds was given to her via an enchanted ring, which was a routine accessory to all non-flyers who come to Cloudsdale now. As opposed to Bow, who dressed in a well maintained tracksuit, and Windy, who dressed in a modest skirt with a blouse and apron over it, Zecora was dressed in what could only be referred to as erotic tribal. Clothes that covered her tits, hips, and part of her ass, but everything else was fully visible; though she did hide it under a heavy cloak when she walked through the city.

“I was told this is where I may be a stallion and mare?” Zecora asked, looking between the two. “Who is seeking one of my brews for their care?”

“Oh? You must be Zecora.” Bow commented, gesturing to the zebra to enter. “Please, please, come in.”

Entering the home, Zecora took off her cloak, her body was just as exotic and erotic as rumors said. Bow and Windy couldn’t stop but stare at her as she seemed to be setting up something. A few small pouches of a spicy smelling herb, some bottles of some liquids, and a mixing bowl. Once she was finished, she turned to look at Bow and Windy. There was an air of confidence about her, as if she had done something like this before.

“Now, I was told through your messages what you desire.” Zecora asked, looking between the two. “Are you sure you wish for the potion I can acquire?”

“Yes, I would.” Bow commented, looking at Windy before continuing. “I would like a foal, to give a sibling for our daughter. But my wife isn’t interested in getting pregnant. So I was thinking…and I’ve spoken it over with her about this beforehand…it’s just…”

“We were told from our daughter that you could…change our genders.” Windy interjected, seeing as her husband was mincing his words. “At first, I was a little against it. But after speaking with my husband, and our daughter, I want to give it a try. We can have a foal, but he’s the one who will carry it. Is that possible?”

“It is possible with my brew.” Zecora commented, walking over to look the ponies over. “It’ll only be a moment for me to craft this for you.” Reaching out, she plucked hairs from both ponies. Placing it in her bowl, she continued. “Sorry, but I needed a bit of hair for the exchange.” Mixing it in, she poured in the pouch of spicy smelling herbs. “To help with this change.”

“It’s fine, just didn’t expect it.” Bow commented, rubbing the back of his head. “Is there anything else we should know about?”

“I shall need you both naked. From pants and shirt to your shirt.” Zecora suggested, not looking away as she slowly poured the liquids into the bowl and started to mix the concoctions together. “Because while this will work, it may momentarily hurt.”

“Wait? This will hurt?” Windy asked, looking back and forth between Bow and Zecora. “I mean…how much will it hurt?”

“Only for a moment, so there is no need to be so direct.” Zecora answered, nearly finished with her potion making. “This is also so your clothes do not get damaged from the effect.”

“I see, okay.” Windy nodded, looking nervously at Bow. “Are you sure about this?”

“She’s a professional.” Bow nodded, starting to take his shirt off. “Besides, think of it like going to a doctor. I have to take my pants off for that after all.”

“I suppose you’re right.” Windy sighed, starting to undo her own clothes. “It just feels…oh nevermind…”

Stripping down to their bare bodies, Zecora looked at both ponies in front of her. Bow had a relatively athletic figure, something she did not expect from how Rainbow Dash had described him. Perhaps he had taken to some form of workout regimen, or something. Regardless, he had a very fit and athletic body, one many stallions his age would be envious about. Windy’s body was equally as alluring, despite her age.

Perky, large, round tits, a thin waistline, wide hips, and a puffy and soft looking pussy. This mare’s body looked like it was born to be bred. How these two met, and how they sired a mare such a Rainbow wasn’t as much of a mystery as Zecora believed. Though Rainbow never developed breasts like her mum, she had her father’s muscles, and her mum’s ass. Finishing up the last remnants of the potion, she handed it to both of them.

“Now, when you drink these potions, similar to a spell one is casting.” Zecora explained as she kept a palm on the cover of each potion cup. “The effects will be instant but not everlasting.”

“Okay, so how long will they last?” Bow asked, looking between the zebra and his wife. “I don’t wanna turn back while pregnant.”

“It shall be no problem, provided you continue to take the proper dose.” Zecora reassured him. “Though while it will last up to seven weeks at a time, I would not want to cut it too close.”

“Alright, so if it lasts seven weeks, we’ll take a potion every five or six. That should be fine.” Wendy replied, looking at Bow. “Ready?”

“Yeah, let’s do it!” Bow replied, downing his potion while Windy drank at a much slower pace. As soon as he finished, he burped and shivered, only to then heave a little. “Ugh…okay…Zecora, was it supposed to taste that bad?”

“Foul taste, but the ideal effect.” Zecora nodded, slowly backing away. “In a moment, you will see that I am correct.”

Within seconds, both Bow and Windy realized what Zecora meant. At once, the two of them felt as if their bodies were burning, bending, and breaking from the feeling. It was foul, horrid, and painful as they hunched over in the stretching pain and increasing temperature. Their bodies were sweating, leaving small pools on the cloud floor. Panting and wheezing, the two of them looked to each other, and then to Zecora, who had now returned to the other potion supplies, seemingly putting something else together.

Bow’s body creaked, cracked, and shrank until it was at that of Windy’s height. His muzzle shortened and became smoother, more feminine. His muscular belly smoothed out, becoming a little rounder, but not overweight, while his coat became a much lighter color, while his mane grew longer and became a wavy texture. His chest slowly swelled, filling out until he was bearing a pair of large and impressive tits. And finally, while his ass was going from flat and firm, to swelled out until it was large, round, and soft, his masculine and impressive cock was shrinking. Within moments, what was once a magnificent pair of cock and balls, were a sensitive clit, and a tight looking pussy.

Windy’s transformation was no better than her husband’s. Her muzzle elongated a little, getting more masculine as hair started to grow along her lip, and cheeks. Her body stretched until it was where Bow’s once was. Her chest flattened until it was gone, with her belly becoming muscular and visibly toned. Her coat darkened and her mane shortened until it was a short and rough looking style. Her wide hips stiffened, and her pussy sealed up. Clutching at her midsection, she hunched over as she felt her new cock growing out of what was once her delicate regions. By the time Windy had settled, the pony’s cock was long, throbbing, and rather impressive; almost rivaling Bow’s former size.

“Very good, a successful transformation with a healthy haste.” Zecora nodded, handing some new potions to the ponies. “Here, drinking this will help with any after taste.” Bow and Windy immediately drank down the contents, sighing and groaning as their new throats echoed out with new voices.

“Well, that was painful.” Bow commented, her voice now sounding softer, but not too delicate. Immediately, she grabbed at her throat. “Is that my voice?!”

“Sounds so, my dear.” Windy chimed in, with his new, harsher and deeper sounding voice. “Oh shit…listen to me, I sound so deep.”

“There we go, I am happy I could offer this relieve.” Zecora nodded, packing up her things. “I shall send more dosages later, so I shall take my leave.”

“Thanks!” Bow nodded, waving a little as the zebra departed. Once alone, he looked to his wife, or rather husband. “So…what should we do now?”

“Well…I’ll admit. You’re looking really good.” Windy commented, feeling his new testosterone fill his loins. His cock was starting to grow in size. “Well, there’s no rush to have a foal yet, but wanna fool around in the bedroom?” Bow leapt at him, as the two started to loudly make out, making their way towards the bedroom and trying out their new bodies.
