The Fertility flower

Yona sat across from Sandbar in a restaurant in at the edge of Ponyville. There were two lit candles burning on the table along with two plates of food. Sandbar was eating some kind of hay casaroll and Yona was munching on what looked like a white ball.

“So Yona, how's the food.” Sandbar smirked.

“Ponies not good at Yak cooking.” Yona frowned.

Sandbar's eyes went wide. “Oh dear. I hope you don't feel like.”

“Smashing?” Yona chuckled. “Yona understand that ponies trying best. Yak just happy to frown at cook on way out. Besides.” Yona twiddled her thumbs. “Yona sign no smashing contract before ordering Yak dumplings.”

“I guess that makes sense.” Sandbar stuck his fork in the casaroll. On his way up to eat said casaroll he dropped his fork when he accidentally brushed up against his breasts.

“Sandbar ok?” Yona nibbled on her dumpling.

“I'm fine Yona, Just not used to having breasts.”

“Yak boobs never been so big before. Yona understand.”

Sandbar nodded. “Thanks Yona.” he went for yet another bite and effectively navigated his giant tits to actually take a bite. “That's a nice dress very.” Sandbar blushed. “Revealing.”

Yona frowned. “Pony not like dress?”

“What? No, I love the dress it's just. “Sandbar paused. “It's not like you dress up in something so skimpy.”

“Sometimes Yona just like wearing little clothing. Especially when so hot. Aside from giant breasts getting in way has Sandbar been having other problems with girl body?”

“Well Gallus summed up many them earlier today but I think he left out just how awkward showers are.” Sandbar rubbed the back of his head.

“How so? Yona shower every other day.”

“Most of the washing is fine but every time I get to the more.” Sandbar blushed. “Sensitive areas. I always slip a finger in, and it just feels weird.”

Yona grinned. “Sandbar not learn to be careful around pussy when washing. Sandbar got lot to learn about girls.”

Sandbar sighed. “Don't I know it... So how's the date?”

“Yona having good time.”

“I'm glad you're having fun. Do you feel like having a bit more fun? .” Sandbar raised his eyebrows and smirked.

“Wait... You want to smash with yak?” Yona tilted her head. “Are you sure? Sandbar have girl body.”

“I'm willing to try something if you're willing to.”

“Yona not really into it. Yona prefer men to women. Sandbar be back to normal soon then we smash.”

“But what if I don't ever get back to normal? What if I'm stuck like this forever.”

Yona sighed. “Yona not think of that. Is Sandbar still attracted to Yona?”

“Of course I am. Just because I change gender doesn't mean I change orientation.”

“Yona just not into girls at. Yona fantasize about men not women.”

“So you don't find me attractive?” Sandbar frowned.

“What! Yona not say that. Sandbar extremely attractive woman. Sandbar most beautiful woman ever but Yona just not attracted to female Sandbar.”

“Listen Yona. I know our professors will find a way to change us back, but I've been thinking... our relationship isn't going well.”

“What!” Yona pounded the table. “How can Sandbar say that? Just because Sandbar girl doesn't mean relationship ruined forever.”

“But it's not just the fact I'm a girl now. I see it in your eyes every time we have sex. You're just not enjoying yourself like you used to. I arranged this whole date hoping you'd have a better time smashing me. But I forgot you're not into girls. I'm sorry Yona. You deserve better than me. Maybe we should see other ponies.”

Yona started sobbing. “But Yona don't want to see other ponies .Yona wanna see Sandbar. Is Sandbar unhappy with smashing?”

“Yona. You deserve better than me. You deserve a stallion that can show you a good time in the bedroom and worst-case scenario you deserve a stallion at all. I just can't be good enough for you no matter how hard I try.” Sandbar's eyes went wide as he watched Yona slap him in the face. “What the buck Yona... you hit me.” he rubbed his cheek.

“Because Yona can't stand to hear Sandbar tear himself down like that. Sandbar worthy friend. Sandbar best coltfirend ever. Yona even wear skimpy dress, so Sandbar will be happy. You are worthy Sandbar and don't let anypony tell you otherwise.”

“But the sex is getting stale and I've got tits.” Sandbar motioned to his knockers.

“Yona don't care about sex or body parts. Yona love Sandbar for who he is inside. Even if Sandbar decides to stay woman forever, Yona try and make relationship work.”

Sandbar's eyes lit up “You mean that?”

Yona nodded. “Yona mean that. Yona might not be into girls but Yona willing to try.”

Sandbar grinned. “Sounds good to me.”

Sandbar meeped as Yona snatched him up by his collar and pulled him in closer. “Sandbar misunderstand.” Yona smirked deviously. “Yona want to try right now.”

“Not like you to be so forward but I'm game.” Sandbar blushed. With the check for the food paid for Yona and Sandbar bolted out of the restaurant. Once outside Sandbar meeped in surprise as Yona snatched Sandbar up and carried him through Ponyville. Eventually, they reached a fairly isolated spot behind some bushes and trees. Once there, Yona set Sandbar down and quickly lassoed him into a passionate kiss. Sandbar blushed as he felt Yona's tits press up against his own. Several minutes later Sandbar broke the kiss and stared into Yona's eyes. “You've got one hell of an outfit Yona but I wanna see my girl like she should be.”

“Mmmm Yona agree.” With a huge shit eating grin Yona ripped off her garments leaving the yak completely nude. “Now Sandbar's turn Yona want to see Sandbar's body.”

Sandbar chuckled. “With pleasure.” Matching Yona's earlier expression Sandbar went to work shedding his clothes. He was pretty clinical about it but Yona just drooled as she watched her 'boyfriend' strip. “So, do you like it?" He waved his tits back and forth.

“Yona jealous, Sandbar have bigger boobs than Yona.” Yona frowned.

“True.” Sandbar giggled. “But you've got the better figure.” He paused. “So umm.” The green pony rubbed the back of his head. “What do we do first?”

Yona closed her eyes and grinned. “Yona have no idea.”

“Hmm. Figured you'd know something, you're the one with experience here.” Sandbar awkwardly looked to the ground.

“Sandbar have point. Maybe Yona masturbate but with Sandbar body?”

Sandbar shrugged. “Eh I've got nothing better.”

Yona grinned as she slipped behind Sandbar and placed one of her hands on his left breast. Sandbar moaned as Yona started caressing and squeezing his breast while her other hand freely explored his thighs. “Oh Yona, That feels amazing.”

“Yona just warming Sandbar up. Sandbar feel nothing yet.” Sandbar moaned as Yona continued her exploration of his body and boobs. He blushed as he felt his nipples start to stiffen and his new pussy leak lubricating fluid. He nearly shrieked out in pleasure as he felt Yona graze his fully erect nipple.

“Sandbar ready for real fun to start?” Sandbar nodded as Yona slid two of her fingers into his winking pussy.

“Oh Yona! Yes!” Sandbar shrieked out as she started furiously pumping her fingers in and out of his pussy. While Yona jerked off Sandbar, she made sure to pinch and caress his nipples. Sandbar moaned again when she felt Yona nip at her neck. “Oh Yona! I feel some...” Sandbar couldn't complete the sentence as he felt a climax radiate from his pussy outward through his body. With Sandbar's climax completed Yona let Sandbar go who slouched wordlessly to the ground. “Sweet bucking Celestia, that felt great.”

“Is pony thirsty?” Yona winked.

“You bet Yona.”

“Get on back.” Yona pointed to the ground. Sandbar almost immediately heeded Yona's instructions. Within moments Sandbar's vision went black as he felt his face quickly smothered by Yona's gigantic ass. He felt Yona maneuver around for a moment until he tasted the familiar taste of Yona's own vaginal fluids. “Pony get drinking. Yona need release.” Sandbar muffled a response as he reached his tongue up into Yona's pussy and furiously started licking up as much juicy Yak jizz as he could. “Sandbar. Oh yes! Right there.” Sandbar heard Yona shout as he lapped at Yona's pussy. He reached out his hands during the delightful cunnilingus and started massaging Yona's soft woolly thighs. Yona's cries of ecstasy became more and more unintelligible as Sandbar's continued eating her out. Sandbar blushed as he suddenly a pair of hands on his boobs.

“Oh Yona.” Sandbar muffled as Yona continued her sloppy but pleasurable groping of his enormous tits. The erotic experience proved too much for Sandbar as he felt his pussy climax again and spray his thighs in cum. A few moments later, Sandbar's mouth was flooded with Yona's cum from her own climax. With Yona's climax reaching it's peak the Yona got off of Sandbar and helped him off the ground.

“Seems Sandbar get magic touch back with Yona. Yak not cum like that in long time.”

Sandbar grinned. “I don't know about you, but I still got a lot of stamina left in me. Wanna try something else?”

“Good idea Sandbar.” Yona grinned. “Yona know what to do next. Yona saw older sister make love to girl next door once.”

“Sounds hot. So what now?”

“Get on ground, but this time get on side.” Sandbar followed Yona's instructions who did the same. “Get closer. Touch Yona vagina with yours.” Sandbar and Yona scooched closer to each other until their pussies where touching. The sensation of Yona's pussy touching his own was more than enough to get him wet again. “Now rub Yona's pussy with yours and Yona do same for Sandbar.” Sandbar did as Yona instructed and started rubbing his pussy along Yona's pussy. He blushed as he experienced pleasure emanate from his vagina as Yona reciprocated. The two of them continued rubbing for a few minutes before Yona changed up her technique; electing to scissor her legs into Sandbar's vagina. Ever the good mimic, Sandbar soon replicated Yona sending both of them to even greater heights of arousal and desire. The both of them sat there scissoring each other for a few minutes before both of them came again.

However that didn't stop the two of them from continuing to scissor each other. In fact their mutual orgasm only encouraged them to continue. Both of them screamed each others names as they continued rubbing their pussies together and cumming near constantly. Eventually, Sandbar stopped and let his thighs drop onto Yona's belly.

“I... can't... keep... going.” Sandbar panted between words.

Yona smiled and got up off the ground and helped Sandbar up once again.

“Sandbar do good. Maybe lesbian experiment what relationship needed most.” Yona kissed Sandbar who reciprocated said kiss.

“Yeah.” They paused for a few minutes before Sandbar spoke once more. “Umm Yona... do your breasts feel...”

Yona's eyes went wide. “Yes.” both of them wordlessly looked down at their busts. The expanding sensation from long before had hit the both of them and both of their boobs were once again jiggling in expansion.

“So that what expansion look like from outside.” Yona pointed to Sandbar oscillating boobs.

“Yeah...” Sandbar blushed. “Listen I don't know about you but. I'm feeling all frisky again watching this.”

Yona didn't respond she only grabbed Sandbar and kissed him again. Sandbar kissed back making sure to thrust his expanding bust into Yona's boobs as much as possible. Eventually kissing became completely impossible once their boobs reached a size so large they couldn't get close to each other.

“Yona wonder how much breasts expand this time?”

“Don't know. But your boobs are still looking as soft as ever.” Sandbar reached forward and fondled Yona's expanding boobs. Yona smirked and started doing the same to Sandbar. They both fell forward onto their breasts once they expanded to a size too massive to support with their legs. Despite the fact that it was getting more difficult to reach out and fondle each other's boobs they continued doing so. Fortunately for the both of them they landed on their breasts in such a way that they expanded into each other rather than away from each other. Several minutes later the expansion ended with both of their tits larger than their entire bodies.

“Yona think expansion stop.”

“I think you're right. Sweet Celestia you're huge.”

“So is Sandbar.”

“You got that right.” Both of them blushed and turned to the source of the voice. Staring wide eyed at the pair of them were none other than the cutie mark crusaders watching the both of them make love to each other. Scootaloo, in particular, had her hand down in her panties as she beheld the sight of them towering above the bushes.

The crusaders had truly grown up into attractive women. Applebloom had the largest boobs of the bunch followed by Scootaloo. Finally, Sweetie bell had been cursed with a fairly flat chest, but she made up for it in well defined thighs.

“Cutie mark crusaders are sure grown up now.” Yona smirked.

“How long have you been there?” Sandbar frowned.

“Right around where you two started shouting each other's names so loud half of Equestria could hear it.” Scootaloo narrowed her eyes.

“Ah never thought I'd see boobs so big. Especially on Sandbar.” Applebloom stared wide eyed.

“I don't know about you girls.” Sweetie bell grinned. “But seeing them all horned up has been giving me ideas.”

“Umm Sweetie belle. Ah don't like the way yer lookin at Scots and me.”

“Give it a rest Applebloom.” Scootaloo put her hands on her hips “I could stand for a bit” Scootaloo was quickly cut off by Sweetie bell planting a kiss on her cheek. Very few words needed to be exchanged as the both of them started kissing each other.

“Guys What the buck are yall doin?” Applebloom shouted watching Scootaloo and Sweetie bell make out.

“Give it a rest Bloom we're old enough to do whatever we want.” Scootaloo returned to kissing Sweetie bell. Before long Applebloom couldn't help but extend a hand down into her panties and touch herself at the sight of Scootaloo and Sweetie bell making out. As Scootaloo and Sweetie bell made out Yona and Sandbar watched two lumps start forming in Sweetie belle's chest. All of the crusaders were too caught up in their sexual fantasies to even notice their breasts, and asses were expanding. By the time Scootaloo and Sweetie bell stopped kissing all three of the crusaders had grown to the similar proportions as Yona and Sandbar were at earlier.

“Wow Scoots never knew what a good kisser you were.” Sweetie bell smirked.

“Oh my gosh Sweetie bell your breasts.” Scootaloo stared wide eyed.

“What about my” Sweetie bell trailed off as she took in her new gigantic bust. “Sweet Celestia I have actual tits now.” Sweetie bell squealed and bounced up and down. "They're so jiggly."

Scootaloo clutched Sweetie bell's breasts. “Welcome to the tit club girl. Allow me to show you how much fun it can be.”

Applebloom slapped one of Scootaloo's hands off of Sweetie bell's boobs. “Ain't yall gonna share some of that with me?”

Sandbar and Yona were left speechless as the crusaders continued sweet talking each other before promptly ripping off each others tattered clothes. Before long all three of them were engaged in fondling each other's breasts. Sandbar blushed as he looked back to Yona who had started touching his bust again. Sandbar smirked and returned to touching Yona's boobs as well. As the day wore on more and more ponies came to the lesbian orgy in the bushes. Any guys who turned up as expected promptly joined the other team. At least half of Ponyville was inevitably drawn to the orgy leaving the entire area hot and wet from feminine cum.
