Spike shook his head as he tried to shake the sounds of Fluttershy's lusty moans from his head. He had run most of the way towards Sweet Apple Acres in case Fluttershy was following him but stopped to regain his breath along the dirt path, it was then he noticed that his huge erection hadn't died and was still pressing against his jeans, making it look like he was smuggling salami in his pants. Spike tried to get the thoughts of the seductive Fluttershy out of his mind as he limped towards Sweet Apple Acres, but his raging erection refused to cease, only becoming stronger as he tried not to think about Fluttershy's huge breasts, her supple thighs, her thick ass and her little pus-

Spike shook his head, ridding his mind of the perverted thoughts while his erection throbbed with strength, rubbing his engorged head against the rough denim of his jeans. He had to deal with his raging boner if he wanted it to go away. If Applejack caught the slightest glimpse of the cock in his pants it would be an exact repeat of what happened at Fluttershy's cottage, only worse. Spike looked around for any would-be spectators before hopping a wooden fence and jogging off into the small forest of apple trees.

Once Spike was in a location where he was sure no-one would find him, he leaned against a tree and very slowly and cautiously pulled his cock and balls out of his fly, sighing slightly at the release as his cock dangled in the air. Looking around again, he placed his two hands around his shaft and slowly started to tug on his huge asset, groaning slightly as the pleasure caused him to tighten his grip.

After a while of jerking his shaft to imaginations of Rarity's fine body, he began to speed up his hands, using his pre-cum as lube as he pulled his foreskin back and rubbed his sensitive head. After a gradually increasing speed of his jacking and the tightness of his grip Spike was close to his orgasm, closing his eyes in pleasure as his body shivered with every slow draw up his dick. He brought one hand down to his balls, squeezing them and rolling the hefty testicles while his other hand was passing long strokes up his cock.

Spike came with a loud gasp, his cock unloading rope after ropes of thick, pearly white cum all over the grass and his hand, his body seizing and his muscles relaxing, sending him sliding to the ground. After his orgasm subsided and the last of his cum dribbled from his cock, he could hear the faint sound of girls giggling. He opened his eyes and gasped as he saw Rainbow Dash and Scootaloo sitting on a large tree branch, looking down at him from their perch.

"Rainbow!? Scootloo!? Wh-h-what the hell are you d-doing!?" Spike asked as he put his softening cock and balls back into his pants.

"Awwww, come on! Don't put it away. I would, like, love to get my throat ruined by that fat cock." Rainbow said in her usual slutty, seductress voice.

"That would be, like, sooooo frickin' hot, Rainbow!" Scootaloo added, looking up at her idol with star-struck eyes.

Rainbow's appearance had changed the most out of the girls. Before the transformation, she barely had to wear bras at her unimpressive A-cup, a tight 30" waist, a small 31" hips, a very flat, muscular rump and a short stature of 5' 3". After the Elements did their strange thing, her breasts grew to a large DD-cup, keeping her waist size of 30", gaining 38" hips, a rounder, and plumper ass and growing to 5' 7".

Her personality stayed pretty much the same, still maintaining her butch, tomboyish attitude and particular style of rudeness. From what Spike could pick up from people in town, Rainbow already had quite the advanced sexual desire before her transformation, often bringing home multiple partners of multiple genders in a month. But after the transformation, she was bringing home multiple partners every week! She wasn't even above waiting until she got home apparently as Spike sometimes saw the girl in alleyways pleasuring men and women alike.

The effects also had their effects on the young ladies of the Ponyville Schoolhouse, including Rainbow Dash's smaller shadow, the recently 19-year-old Scootaloo. Before the transformation and the subsequent spread of the 'Bimbo Plague', Scootaloo was dealing with becoming a fully-fledged adult at age 18, following in Rainbow's footsteps in mind and body. She followed the stereotypical Pegasus-Blood body type, small breasts, small waist, small hips, small ass and small stature. After the Elemental effect, her breasts grew to a larger C-cup, her waist was about 29", her hips 37" and her rump became plumper but she kept her small height of 5'.

Surprisingly enough, her personality and lust for sex hadn't changed at all. Apparently, the young girls of Ponyville were a lot less sex-crazy than the grown females and were almost immature instead of sexual, often snuggling and kissing various boys instead of providing the kind of pleasure that the grown men of Ponyville were accustomed to. Spike didn't ask why the girls acted like this as he had given up getting to the bottom of the ridiculous mystery of the Elements.

Spike couldn't help but look up at the giggling girls and notice what they were wearing. Rainbow was wearing her usual flying garments, an incredibly tight, sky blue tank top and a pair of black, spandex exercise shorts that was practically a thong it was so small. Scootaloo was wearing a similar exercise centered costume, a tight, orange sports bra and a pair of snug yoga pants.

"Look at him, Scoots. That piece of meats gonna be all yours tonight." Rainbow said, gliding down to the ground and slowly strutting towards Spike. Scootaloo followed suit, giving him a half-lidded look as he seductively strolled over to the blushing boy.

"I have to go to the bathroom!" Spike shouted, shooting up and sprinting off through the apple orchard.

After Spike was a purple and green dot on the horizon, Rainbow and Scootaloo looked at each other, biting their lips as they stifled their laughs. The previous scene was too much for them as they both guffawed loudly, falling to the ground as they rolled in laughter.

Author's Notes:

Thank you Portal82 for the idea that the younger girls are more immature than slutty. Much appreciated.

Sorry about that moderator but, I was being silly
