The day before the change; at the Cutie Mark Crusaders' Clubhouse; Apple Bloom was setting up some snacks with a few other things on a table. "Okay, got everything ready for our job to help Rumble and Button get their cutie marks." She said as she turned to Sweetie Belle and Scootaloo who were setting up some bean bag chairs, as they dragged them around.

"So why did Rumble decide to get a cutie mark in the first place?" Scootaloo asked with a brow as she sat down in one of the bean bag chairs. "Wasn't he all against it at first?"

“Well yeah, but after all his buddies got one, he felt left out.” Sweetie Belle mentioned with her usual warm tone. "Plus, Button Mash also wants one too and who am I to turn down to help out somepony needs help getting a cutie mark?"

"That, and you like him…~!" Scootaloo teased Sweetie as it caused her to blush.

“N-no I d-don’t!” Sweetie reflexively responded.

“Oh, please. You can’t even say that with a straight face.” Apple Bloom interjected. "Besides, there's no reason not to admit your feelings that you like someone. At least that's what Applejack told me."

"Speaking of which, what exactly is your sister up to?" Scootaloo asked with curiosity.

"She's with her friends at Twilight's Castle to discuss something with the princesses." Apple Bloom replied.

"Oh yeah, Rarity told me about that before I left to come here." Sweetie Belle mentioned before they heard a knock at the door. "That must be them." Apple Bloom went up to the door and when she opened it, she was surprised to see not only Rumble and Button Mash, but Tender Tabs with them as well.

"T-Tender, what are you doing here?" She asked him with a surprise tone.

"Well, Rumble and Button Mash said that they're heading to your Clubhouse to help get their cutie marks and I kind of wanted to see you again." Tender replied with a smile. "I kind of want to see how your dancing is doing, you know since you're still taking the whole dancing class and stuff." Apple Bloom had a small blush on her face when he mentioned that before she felt Scootaloo giving her a nudge on her side.

“Well, well, well, looks like Sweetie Belle isn’t the only one who has a crush~.” Scootaloo whispered which only earned her a shove from Apple Bloom.

"Well, come on in." She told the three colts as she stepped aside and let them in. “Welcome to the Cutie Mark Crusaders’ Clubhouse.”

"Wow, this place is so cool!" Button complimented. "Wish I had something like this."

"Yeah, and you girls already know why we're here." Rumble mentioned before he scratched the back of his head. "And I want to say I'm sorry about the rough time I gave you girls during that whole camp thing."

"Hey, water under the bridge dude, it happens." Scootaloo said with a shrug before she sat down in one of the bean bag chairs. "Anyway, I wanted to say that the food you made back at the camp was really good."

"Thanks." Rumble replied as Tender handed him one of the apple juice boxes.

"Okay, let's get down to business." Apple Bloom spoke up. "Let's start with Button Mash, what exactly do you like to do at times?"

"Well, I really like to play video games." Button Mash mentioned. "It's really fun to do and I sometimes dream of making my own kind of video games myself."

"Wow, that sounds really interesting." Sweetie Belle told him with a warm smile. "Maybe you can be like a--" She was going to tell him right before the sky suddenly turned pink as a pink light shined through the windows of their clubhouse. They then had blank looks on their faces as their eyes glowed pink and Sweetie Belle lost her train of thought. "What was I saying?" It seemed each of them forgot what they were talking about or doing before Scootaloo looked over at Rumble and had a smirk when she looked down at his crotch area.

"Hey Rum, are you growing a boner or something?" She teased while pointing towards the tent forming in his pants.

"What?!" Rumble shouted in shock before he quickly uses hands to cover the tent. It wasn't just Rumble, it's also Button Mash and Tender Taps who seemed to be growing boners in their pants while the Cutie Mark Crusaders just looked at them with interest.

"Hey, there's nothing to be ashamed about." Sweetie mentioned as she walked over to Button. "I think my sister told me that whenever a stallion has a boner in front of a mare, it means they really like her. And I saw you looking at me when you grew that boner, Button~."

"W-Well I…uh…Whoa!" Button yelped when Sweetie Belle suddenly dug her hand into his pants to grab his cock.

"Wow, it feels bigger than it looks." She said as she used her magic to pull down his pants and underwear.

"Wow, she's really bold." Tender mentioned before Apple Bloom pulled down his pants to let his cock free.

"She ain't the only one, sugar cube." She said it as she slowly started to stroke his cock. "I bet you were thinking of me when you were having this boner here."

"W-Well, I do think you do have a cute butt." Tender mentioned, as he was feeling pleasure just from Apple Bloom stroking his cock. They then heard a muffled noise before they looked over and saw Scootaloo on top of Rumble with her lips locked with his while he had no pants on and she was stroking his cock at a fast pace.

"Whoa Scootaloo, don't you think you're being a little rough with him? Sweetie asked as none of them noticed her breasts were becoming a bit bigger and the muscles on the colts were bulking up. Soon, all the crusaders’ breasts were growing, as well as their asses. Then, the clothes that Applebloom and Sweetie pulled; or were pulling, were shrinking and becoming thinner. The girls’ clothes were all getting shorter until they either disappeared, or were almost snapped off by their enlarged forms.

"Oh please, his cock's getting harder and harder, which means he's loving it." Scootaloo told them smugly, after she broke the kiss and a string of saliva still connected their mouths. She then went back to roughly making out with him as her clothes became smaller and straps suddenly appeared around her waist and arms.

"Well, I never expected her to have a thing for him." Sweetie mentioned before she let out a surprised gasp when Button suddenly slid his hand into her pants and began to finger her cunt. "B-Button…!"

"Hey, I just want to return the favor." He said with a small smile. Button then leaned in to whisper into her ear. "After all, I do this to my mom sometimes and she loves it~." Hearing him whisper that suddenly turned her on even more, as she felt herself getting wetter by the second. As the two of them then started to make out, they seemed to be growing taller and Sweetie Belle's lips suddenly had lipstick on. Apple Bloom then pulled Tender Taps over to another bean bag chair as it suddenly looked like the shape of a heart before she pushed him onto it and got down on her knees.

"Here, let me help ya out more, Tender~." She said before she started to lick the length of his suddenly growing cock, starting from his balls and going all the way up to the tip. Tender let out a pleasurable groan as Apple Bloom repeated this process about a few times. They too seemed to be getting taller as Apple Bloom's muscles became firm and her ass grew a bit larger.

Meanwhile, Scootaloo was getting a boob treatment from Rumble, he was on top of her and he was going all in on her breasts. He buried his muzzle into her left breast and was biting her nipple, at the same time he used his hands to squeeze her other breast and tug on her small wings. "Fuck yeah~." She moaned as she sounded a bit older. "You like tugging my wing, stud~?"

"You started it, now it's my turn." Rumble said before he flipped himself and her so then he was on top. He then yanked off her bottoms and started to bury his face into her wet cunt. She grabbed tight on the bean bag chair as he was roughly eating her out. She locked her muscular legs around his head as she let out moans of pleasure from the feeling of his tongue inside of her.

As this was happening, Sweetie Belle had removed her clothing as she was letting Button Mash eat her out while she was still standing. Her breasts have become even bigger while her lips became thicker. "Ooohh Button~!" She moaned as his cock grew longer and bigger while he gently held his head.

As for Applebloom and Tender, she was now giving him a full blowjob as he laid on the floor. “Hrgh! Oh, Fuck!!! How are you so damn good at this!?” He groaned out loud.

“Dunno, just feels right.” She briefly pulled out to speak. Applebloom then quickly dove back in and deepthroated him once more.

Rumble had flipped Scootaloo onto her stomach as he was now plowing her ass. While he was on his knees, he gripped Scootaloo’s legs and repeatedly tugged on them to slam his phallus deep inside her pucker.

“AH!! Ah~! AHHH!!!” The young pegasus couldn't stop screaming as he stretched her insides like never before.

After several minutes of this, Sweetie was now on the ground with her legs wrapped around his neck, as he devoured her hungry pussy.

Scootaloo was on her hands and knees while she raised her ass for Rumble, while he was pounding up her insides. Her moaning was now almost like babbling as she was nearly incoherent from all the ass-bucking she had gotten.

Applebloom and Tender got into a 69 position as they orally pleasured each other. With him pinching her ass cheeks while slobbering at her wet snatch. And with her stimulating his balls with her fingers as she swallowed his length.

Soon, all three couples were reaching their limits as they were about to cum in/on their lovers.

Sweetie grabbed the back of his head, and pressed his muzzle as deep inside her as she could. She screamed as loud as her sister could, spraying Button’s face with her wet cum. Applebloom tightened around Tender’s tongue as she released her marecum like a waterfall. Prompting him to raise his hips and shove his cock down her throat. Her grunted hard, as he spasmed in her gullet, shooting his hot semen into her stomach with each thrust he made. Scootaloo was now moaning while closing her eyes, barely able to handle this. Rumble soon gave one, last, hard, SLAM into her ass, and filled her bowels up with his spunk.

Soon, each of them pulled away as the three Colts' muscles ripped through any clothing they had left while Apple Bloom suddenly had a very large ass and strong firm muscles. Sweetie Belle had thick lips with big breasts as she had two ponytails and a small fur coat around her arms. Scootaloo had multiple belt straps wrapped around her arms, legs, and her waist, with nothing underneath; as her body looked more muscular and she suddenly had a pierced tongue.

"We ain't done yet~." Apple Bloom said as she sounded much more mature before she got off of Tender and leaned against the large pink table in front of him. She then spread her ass cheeks as she looked at him with lustful eyes. "That rod deep within my ass~. I want us to feel like we're both in heaven~." Tender grinned as he got up and went over to her. He then grabbed hold of her hips while aiming his still erect cock right towards her asshole before poking the entrance with his tip, just to tease her.

"I have to say, your ass is so nice and thick~." He complimented as he also sounded mature.

"Us Apples always have thick ass-AAAAAAHHHHHHH!!" Apple Bloom cried out in pleasure as tender wasted no time pushing his cock forward and rapidly thrusting inside of her. She let out pleasurable moans with each thrust and loved every second of his cock piercing her ass. Meanwhile, Scootaloo and Sweetie laid on their sides on an adjacent table and mashed their bodies together. They spread their legs and revealed their soaking wet, winking, desperate pussies to the two prone males.

“Come and get us, boys~...” They both said to them while giving their best bedroom eyes. Rumble and Button happily obliged and slammed their still hard cocks into their awaiting depths. They held their mare’s leg as they thrusted into both of them together.

"FFFFUUUUUUUUCCCCCCCKKKKKK~!" Sweetie Belle moaned out as Button Mash thrusted inside of her. She could feel his cock piercing her womb before he leaned forward and gave her a loving kiss on her neck while squeezing her breasts.

"Are these implants?" He asked her through his grunts.

"R-Rarity gave me th-these, said I…oh…look like a v-very sexy doll~." Sweetie Belle said through her moans as Button continued to kiss her neck and squeeze both her breasts.

"I love them~." He told her before the two of them shared a loving make out session while he continued to pierce her womb with his cock. The room was not only filled with moans of loving pleasure, but rough grunts and curses as Scootaloo and Rumble were having a rougher fuck session with each other as they loved it.

"Oh yeah, that's right prick, fuck that slutty pussy!" Scootaloo grunted as she dug her nails into his back while he held tightly on her legs.

"You're more than a slut, you're fucking bimbo, cunt!" Rumble grunted back before the two started to roughly make out with each other. The entire clubhouse, that had gone bigger all of the sudden, was filled with the sounds of moaning and the sounds of flesh being slapped against each other. Once in a while, they switch things up as two Crusaders were watching from the sidelines while one of them was having three of the colts at once.

Apple Bloom had both Rumble and Tender plow inside of her two lower holes while she sucked hard on Button's cock. Later, Sweetie Belle had both Button Mash and Rumble thrust inside her cunt at once while Tender thrusted between her breasts. Soon Scootaloo had her turn as she was roughly jerking off both Button and Tender while Rumble was thrusting up in her ass. They seem to be going at it for hours as the sun had set and each lover was back to their one. Each colt was feeling their cocks throbbing inside of their lovers as they continued to thrust into their wombs. Soon all six of them came together as they shouted 'I love you' at the top of their lungs. Tender, Button, and Rumble had filled up Apple Bloom, Sweetie Belle, and Scootaloo with their semen as each of them felt exhausted before they all collapsed onto the floor.

After the six horny teens had completed their mating, they’d passed out and slept through the rest of the evening, the night, and they only awakened by sunrise. Apple Bloom and Scootaloo set up on top of Tender and Rumble before they heard slurping sounds coming from over Sweetie Belle and Button Mash. They looked over and saw her sucking on his cock as he had morning wood, just like Tender and Rumble do. The two crusaders decided to follow her example and began to suck on their lovers' cocks as well. Each of them groaned in pleasure as they were being sucked off as fast and hard as they could get. Soon each of them bucked their hips as they released a stream of semen down their lover's throats. Each crusader swallowed their lovers' semen before releasing their cock as all six of them decided to have one quick morning fuck session.

Soon after, the crusaders had decided to go for a walk into town with their colts before having some more fun later. Oddly though, they didn't feel the need to wear any extra clothing, so they just waltzed into town the way they already were. As they did, they saw that every creature in sight was just like them. Everypony was almost, or totally naked, their assets had grown significantly since the day before. And many of them were simply having sex out in the open.

The colts and young mares don't feel put off by anything, so they were just casually chatting about ‘regular’ things. “So you really want to do this with me?” Tender asked.

“Yeah, I think you’d be great at making a porn film or two, Tender. And I'd be happy to join you, if you know what I mean~.” Applebloom said while wiggling her brow at him. "Just think about it, you and me, we start off by dancing before we get to the fucking~." She whispered into his ear which caused his cock to spring up.

“So we’ll meet up every now and then?” Scootallo asked Rumble. "Have a good rough fuck, no matter where we are. You plowing my ass, throat, and cunt~."

“You choose, we’ll get to have a good fuck wherever we are~.” Rumble told his now ‘friend’ with benefits before the two of them shared a hot make out session.

“Heh, I’ll get to do all that, and more, on dates with my coltfriend.” Sweetie said, while holding hands with Button, and giving him a kiss. "Btw, you gotta take me to your place sometimes for a threesome with your mom~." She whispered to him with a lustful tone.

"You're such a bimbo, you know that~?" Button replied before pulling her in close, and lifting her up by the hips. He then thrusted his cock right into Sweetie Belle as she let out a pleasurable moan from the feel of her lover's cock inside of her. She wasn't the only one as Scootaloo got roughly pinned down by Rumble and he started plowing into her cunt. Apple Bloom, on the other hand, positioned herself on top of Tender’s lap, before lowering herself into his meat pole before she started riding him in a cowgirl position. All three Cutie Mark Crusaders moaned in pleasure as their lovers continued to plow them in the middle of the street, but no one seemed to mind as there were others that were fucking each other out in the open, and they didn't care why they were doing it in the first place.
