Chapter 1

It was a clear sunny afternoon at Canterlot High. Most of the other students had either already gone home or were over by the sports field watching the soccer game against Crystal Prep.

As Tidmouth had never been that bothered about sports he chose to hang around elsewhere. He was waiting to meet up with Rainbow Dash.

They’d always go over to her place after a big game and indulge their shared fetish of well-worn socks and sweaty feet. Tidmouth often felt a little bit guilty about doing kinky stuff without Twilight, but he knew she didn’t mind, so long as she got invited every now and then. Tonight, however she was busy studying so it’d be just him and Dash.

Tidmouth overheard a distant whistle and some cheering marking the end of the game. A couple of minutes later Rainbow Dash came sprinting around the corner toward him.

“Hey! You ready?” she asked excitedly hopping from foot to foot.

Tidmouth blinked in surprise. She seemed unusually eager, hopping from foot to foot as she grinned widely in his face. Her clothes were very scruffy and unkempt, almost as if she’d gotten dressed in a hurry. “Oh, hey Dash. Yeah, I’m ready.”

“Great!” She frantically grabbed him and started jogging home, barely giving Tidmouth enough time to grab his belongings as she dragged him along behind her.

* * *

They soon made it to Rainbow’s house. It wasn’t much but she’d been desperate to move out from her parents’ house as soon as she could. She loved them but she found it difficult to keep her private moments private when they were around.

She hurriedly opened the door and scrambled inside. Tidmouth stood for a moment on the porch, trying to catch his breath
“Come on!” Rainbow called, grabbing him by the shirt and pulling him inside. She finally let go of him when they reached the bedroom.

Tidmouth smelled the familiar scent of dirty socks. He was pretty sure she put off doing laundry as long as she could avoid it... and that was turning him on. Before he got too carried away, however, he put up a hand. “Rainbow, hold on a sec. What’s with all the rush?”

Rainbow took off her sports jacket and tossed it onto the back of a nearby chair. “Oh, right, sorry! I got a little excited. I got a surprise!” she sat down on the bed and dangled her feet in the air.

Tidmouth raised an eyebrow but still assumed his usual, shoe-removal position. Having done this quite a few times now he was getting quite adept at untying her shoelaces with his teeth, though this time they seemed rather loosely done up. “She really did get dressed in a hurry.” He thought to himself. He untied both shoes and slipped them off over his head.

Rainbow’s damp soles were now resting on his face. He hummed happily to himself as he sniffed at the sweaty socked feet. He paused and sniffed more closely at her right foot. It smelled kinda different to the left one, a good strong smell, but still somehow different. He pulled back to take a look and blinked in surprise. The right sock was indeed different. Instead of matching the dark blue sock on her left foot, this one was purple with yellow stars.

“Surprise!” giggled Rainbow, wiggling her toes.

“Wha- where did that one come from?”

“Trixie leant it to me after I lost one of mine. …wait, that wasn’t you, was it?”

Tidmouth bit his lip and looked to the side. “I uhh… sorry. I didn’t get a chance to give it back.”

Rainbow smirked and shoved her feet into his chest. “Well, as your punishment, you can give me a foot rub... you filthy pervert.”

Tidmouth chuckled shyly and took hold of them. “Y-yes ma’am.” He got to work, and Rainbow leaned back with a happy sigh.

As he pressed his digits around her feet, he sniffed happily at the sweaty aroma coming from them. He kept being drawn towards the right one, however. He guessed this must be Trixie’s scent.

Maybe these were the socks she wore under those tall blue boots in the colder months. He shuddered with pleasure and felt his erection tenting in his pants.

Rainbow looked down at him. “You’re really liking the surprise, huh? Lemme get a try of that.” She pulled her right foot away from Tidmouth and leant down to smell it herself. “…Mmfhh~ Damn! I might have to try and borrow Trixie’s dirty laundry more often. She’s got a real good funk!” she squirmed a little. “Actually, that’s really good… I ahh… gimme-a-sec!!”

Rainbow slipped the sock off her foot and held it to her nose, sniffing deeply. She slipped her other hand down the waistband of her pants and started frantically fingering herself. Tidmouth’s foot massage became more and more sloppy and unfocused as he became distracted by the erotic display and the tent in his pants became harder and harder.

As usual, Rainbow was a quick finisher and barely two minutes into her manic masturbation session she shuddered and came, giving one last deep whiff of the sock in her hand before looking down at the wide-eyed Tidmouth looking up at her. “Woah… oh… heh, sorry Tidmouth. You must be ready to burst after seeing that. How’s about we strip down, and I’ll jerk you off.”

Tidmouth didn’t need to be asked twice. He pulled off his shirt and hoodie, kicked off his shoes and dropped off his pants and underwear. He sat on the bed and pulled his legs up, facing Rainbow.
She reached down and pulled a discarded rainbow-striped sock from the floor. She knew it was one of Tidmouth’s favourites. She slipped it over his cock and held Trixie’s sock over his nose as she started to tug him off.

He moaned as he sniffed happily at Trixie’s sock. Despite Rainbow running around for an entire soccer match in it the smell was still very much new to him. Rainbow’s scent was merely an afterthought.

He could only imagine what Trixie's socks must smell like on her own feet. If she was able to over-power even the smell of Rainbow Dash, then her smell must really live up to her ‘Great and Powerful’ persona.

Rainbow watched as he glazed over in bliss. She didn’t notice the sock starting to glow slightly. Nor did she notice Tidmouth’s testicles slowly swelling to an unusually large size.

Tidmouth winced slightly. “Ah!”

Rainbow paused. “What’s up?”

“I- I dunno. I just feel… really pent up all of a sudden. Just keep going, I- I’m pretty close.”

“Alright dude.” Rainbow nodded and resumed her motions.

Tidmouth huffed at Trixie’s sock and shuddered as he felt his orgasm approaching. He moaned as the first wave squirted into the sock. He felt the second spurt, closely followed by a third… and a fourth… and a fifth?! He just kept cumming.

Rainbow’s eyes widened as she watched him pump load after load into her sock. The end bulged out and slopped down as it slowly filled up with cum.

After a solid 30 seconds of ejaculating, Tidmouth finally ceased and gasped for breath. “Woah…”

“You good dude? I know you said you felt pent up but, I’ve never seen anybody cum that much before!” Rainbow slipped the sock off his cock and dangled it in the air. The end was sagging and slowly leaking about half a pint of spunk.

Tidmouth looked at the sock, slightly mesmerised by it. “I’m just as surprised as you. …Maybe I should call Twilight.”

“Yeah… maybe…” Rainbow looked at the soggy rainbow-striped sock in her hand before moving it to her face and slowly licking over the end.

“Rainbow!”

“What? It’s not like I’ve never sucked your cum through a sock before!”

“Y- yeah but, …shouldn’t we be worried? This doesn’t seem normal.”

Rainbow had practically shoved the entire end of the sock into mouth. She pulled it out leaving a cummy-saliva trail connecting her to the sock “Dude, we meet up once a week to masturbate and smell each other’s feet. Who needs normal?”

Tidmouth rubbed his neck. She had a point. And he had to admit, watching her was extremely arousing. He picked up Trixie’s sock off the bed and gave it another deep sniff.

“A-HA!” said a voice from outside.

Tidmouth and Rainbow wheeled round and saw Trixie standing outside the window, glaring in at them.
“So, not only did you steal Trixie’s lucky sock, you also let that creep use it for his perverted fun!”

“T- Trixie! I- It’s not what it looks like!” started Rainbow

“Oh no! Trixie thinks it’s exactly what it looks like!”

Rainbow scrambled off the bed and opened up the window. “Look, Trixie… I’m sorry. Just… please just come inside and hear me out.”

Trixie raised an eyebrow and paused. “Fine.” Trixie raised a leg and clambered through the open window. She dusted herself down and strode over to Tidmouth, snatching the sock from him. “That is property of the Great and Powerful Trixie, and she did not give you permission to borrow it!”

Rainbow put her hand out toward her. “Trixie, calm down. It’s not his fault, honestly. It’s mine. We both have this thing for… used socks—”

Trixie sniffed the air and grimaced. “Ugh… Trixie can tell.”

“Heh… exactly. Look, when you let me borrow your sock today, I just thought it’d be a neat little surprise for both of us. Something new. Just for one day. I swear, I was going to wash it and get it back to you tomorrow.”

Trixie continued clutching the sock closely to her chest, eyeing them both with suspicion. “Trixie is not sure she approves of you thieving her personal belongings for your own perverted pleasures.”

“I know, and again, I’m really sorry you had to find out this way, Trix.” Rainbow put a hand on Trixie’s shoulder. “Just… if you’re going to tell, don’t get Tid involved. He didn’t know anything about this.”

Trixie squirmed. “Trixie never said she was going to snitch.”

“You weren’t?”

Trixie shook her head. “What would Trixie even say? ‘Trixie leant Rainbow Dash her sock and then she took it home to get off with it!’? That hardly sounds plausible. Vice Principal Luna would never believe me!”

Tidmouth and Rainbow exchanged a look. They knew too well she probably would.

Trixie glanced down at the bed and saw Rainbow’s striped sock, still oozing cum everywhere. “What on Earth is that?!”

Tidmouth squirmed. “Uh… I-I did that…”

Trixie’s eyes widened “All at once?!”

He nodded shyly and looked at the floor.

“Is that normal?” Trixie's hand gravitated toward the sock to pick it up but she hesitated.

“No. I- uhh, I don't really know what came over me.”

Rainbow snickered “Sure wish you'd came over me!”

Tidmouth gave her a light shove “I'm serious! What if something’s really wrong with me?”

“Trixie thinks she knows.”

Tidmouth and Rainbow looked up at her in surprise.

“Trixie thinks her socks might have some kind of ...magical ability.”

Rainbow scoffed “Come on, Trixie. For real?”

“Trixie is serious! It’s nothing spectacular but... Trixie has noticed they seem to be able to grant a person's strongest desires.”

Rainbow pondered for a moment. “Wait, now that you mention it, it did feel as if my right foot kinda had a mind of its own during the match.”

“Exactly! You desired victory, so the sock made it happen!”

“Woah. That's awesome!” Rainbow beamed. “But what about this though?” she said, looking again at the cum-filled sock

There was a pause and both girls turned to look at Tidmouth, who was red with embarrassment. “W-well, I guess I might've fantasised about having a bigger load before. “

“Wow! So, the sock made it happen! That’s awesome! How did it feel?” asked Rainbow, eagerly.

There was a pause before Tidmouth laughed shyly “Really good, actually. Never nutted like that before in my life.”

“Would you like to do it again?” queried Trixie, suddenly

Tidmouth’s face flushed with embarrassment again “W-what?”

Trixie’s eyes narrowed and her mouth curled into a smirk “Oh, you do. Trixie can tell in your face.”

Tidmouth shrunk back, unable to form a response.

“Don’t be so afraid, Trixie will let you borrow her sock again. In fact…” Trixie paused, lifting the sock to her nose, and breathing in deeply “Trixie desires to watch you do it.”

Tidmouth squirmed as he felt himself getting hard again.

Rainbow stroked her fingers around his hardening length and grinned at him “How’s about I give you a blowie?”

Tidmouth considered. “Hmm, I dunno whether Twilight would approve…”

Trixie scoffed. “You’re actually turning down a blow-job? You’re stupider than Trixie thought.”

Tidmouth furrowed his brow “H-hey!”

Rainbow rolled her eyes “Oh go on, Tid. It’s not like we’re having actual sex. Besides, Twilight knows we’re just friends.”

Tidmouth sighed “…Alright then.”

“Sweet! Scoot back and make yourself comfortable and I’ll get started.”
Tidmouth sat back, spreading his legs as Rainbow knelt on the end of the bed
“Ready?” she asked

Before Tidmouth had a chance to reply, Trixie held her sock across his face. He sniffed deeply and noticed something different. The smell was stronger than before and there was no hint of Rainbow anymore. He crossed his eyes and saw the sock was indeed different. This one was deep blue in colour and still felt warm.

He looked across at Trixie and she held up the blue trainer she was no longer wearing. “Thought I’d give you something fresh to get you started.” She said before dropping it on his face. She turned to look at Rainbow “Feel free to get started, but don’t let him finish too quickly. Trixie’s got to warm up her grand finale.”

Rainbow nodded and leant forward on her elbows. She suckled the tip of Tidmouth’s penis eliciting a stifled moan from him.

Trixie snapped her fingers. “Hey, cum-boy, eyes on me.”

Tidmouth turned his head to face her and watched as she sat down on a chair by the window and extended her bare foot towards him. She wiggled her toes enticingly and flashed him a devilish smile.
She pulled the star-print sock from her pocket and gave it another quick sniff. “Hmm, yes. Definitely in need of warming up.”
She pulled her foot towards herself and gently slipped her toes into the sock’s opening. She pulled the sock up her foot and over her ankles, going as slowly as possible to tease Tidmouth.

Tidmouth whimpered quietly as he watched Trixie. Though he didn’t like to admit it, her teasing was working.

Trixie pulled the sock up to its full length and flexed her toes with a satisfied sigh. She sat forward and nabbed her empty shoe from Tidmouth's face, teasingly wiggling her socked toes one last time before plunging them into the sweaty depths.
“There. Now for act two.” She stood up and sidled around to Rainbow’s rear and chuckled softly as she examined her privates. Trixie pinched three of her fingers together and teased around Rainbow’s twat.

Rainbow moaned around Tidmouth’s penis, slightly gagging in the process.

“Breathe.” scolded Trixie. “We’re not gonna be able to have any fun if you pass out on us.” Rainbow mumbled an apology and started gently bobbing her head up and down around the end of Tidmouth’s cock. Trixie rolled her eyes and returned her attention to the blue girl’s rear.

Rainbow’s pussy was already glistening with wetness from Trixie’s earlier teasing and her clit was pulsing with excitement as Trixie leant close.
Trixie extended her tongue and gingerly drew it around Rainbow’s sex. Rainbow shuddered with anticipation as Trixie explored deeper, tasting the juices from Rainbow’s previous orgasm.

Tidmouth watched Rainbow squirm with pleasure, her blow job was getting more and more sloppy as she became increasingly distracted. He didn’t mind though. Trixie’s fresh sock was enough to keep him hard.

Beads of sweat were forming on Rainbow’s forehead. She was trying super hard to hold back her impending orgasm, wanting to make this last as long as possible.
Trixie could tell Rainbow was holding back so plunged her tongue even deeper with rough, quick strokes.
Finally the dam broke and Rainbow came, flopping forward and squirting her juices right into Trixie’s awaiting mouth.

Trixie swished her tongue around her mouth and smacked her lips. “Not bad. Trixie has tasted worse.”

Rainbow didn’t say anything, she just dozily looked up from Tidmouth’s crotch and sighed with pleasure.

“Come on, don’t go falling asleep on Trixie!” the magician said, snapping her fingers. “Trixie thinks Cum-boy here is going to blow the biggest load of his life and I don’t want you spilling a single drop!”
Rainbow and Tidmouth exchanged a glance but nodded at Trixie.

“Good, then let’s begin.” Trixie scooted the chair closer to the bed and started to slowly pull off her shoes again. She lifted her knees to her chest and sat her socked feet on the chair.
She grabbed the blue sock from Tidmouth and dropped it into one of her trainers. “You won’t be needing that now.” she said before extending her leg with the magic sock and resting it on his face.

Tidmouth sniffed deeply and hummed with pleasure. His erection in Rainbow’s mouth pulsed with new found energy and he felt a tingling sensation in his balls.

“That’s it.” Trixie soothed. “Take a good long huff, Cum-boy. Let the sock grant your desires and then fill this slut full of your thickest, gooiest load.”

Tidmouth took another deep whiff and winced with unease. He could feel his balls growing heavier and rounding out as they produced more and more spunk.

Rainbow looked down as she resumed her blowie and could see Tidmouth’s nuts slowly swelling and doubled her efforts, excited to taste his cum fresh from the source.

Trixie too could see his balls expanding and grinned with pleasure. “Is that all you’ve got? Is that truly all you desire?” Tidmouth quickly shook his head. “Then desire HARDER! Trixie wants you to cum like a fire hose.”

Tidmouth strained through the discomfort and tried to fill his mind with thoughts of things like water balloons. He recalled videos on the internet of people doing stunts with water balloons that could expand up to 6ft wide. Could his balls physically get that large without permanent damage? He was brought out of his stupor as he felt a sudden sharp pain, followed by a loud sloshing sound.

Rainbow had pulled back in awe. Tidmouth looked like he was attempting to squeeze an unusual tan-coloured pumpkin between his legs. His balls were so big they were forcing his legs further apart and lifting his butt off the bed.

Tidmouth gasped with a weird mix of pain and pleasure. He needed to nut right now and quickly waved Rainbow to resume her position.

Rainbow nodded and pushed herself down to the hilt. Tidmouth’s penis must’ve grown slightly as well as it was now much further into her throat than before.

“Well then, what are you waiting for, Cum-boy?” Trixie lifted her other foot to her face and sniffed at her socked foot. “Trixie desires you to cum.”

Tidmouth cried out as the flood came. His penis swelled with seed and lodged itself firmly in Rainbow’s throat.
Rainbow took a deep breath through her nose and braced herself. She started fingering herself as she felt Tidmouth blow load after load right down into her stomach. Even if she could’ve pulled his cock free she wasn’t going to. She didn’t want to waste a drop.

Trixie watched as the masturbating Rainbow diligently gulped down Tidmouth’s spooge. She adjusted her sitting position and started pleasuring herself at the incredibly lewd display before her.

Rainbow’s belly slowly started to round out as it filled with Tidmouth’s cum. She used her free hand to rub it, feeling the churning mass inside. This made her shudder and cum once again.

Seeing Rainbow climax pushed Trixie over the edge and she came as Tidmouth’s balls finally finished transferring their contents to Rainbow’s stomach.

Tidmouth blinked, feeling slightly woozy after such a long and powerful orgasm. He looked at the two girls. Trixie was leaning back in the chair breathing softly. Rainbow was curled up at the end of the bed, rubbing circles across her swollen tummy. He scooted forward and reached a hand out to touch it himself.

Rainbow blinked at the contact and smiled at Tidmouth. “This is- *urp!* ...the hottest thing we’ve ever done.”

Tidmouth nodded in agreement as he pressed a finger into Rainbow’s midsection.
“Pity we’ll never get to do it again though.” he said with a frown

“Says who?” The pair looked up at Trixie who was sitting cross-legged on the chair smiling at them.

“Y-you mean-?”

“Trixie also thought that was incredibly arousing. If you want to do that again Trixie may let you borrow her socks again in future. …Providing you invite her to watch sometimes.”

Tidmouth and Rainbow nodded excitedly “Of course!”

“Maybe you’d like to get a load yourself?” enquired Tidmouth.

Trixie chuckled, putting her trainers back on “Maybe someday, Cum-boy. For now though Trixie needs to head home.”

“Alright then. Bye Trixie. And… thanks for all this.”

“No, no… Thank you …Tidmouth.”
