Nano-Norman

Norman couldn’t tell where Twilight was going, but he could feel the swinging of her legs and the forward motion of her body. Every once in a while, he felt a rhythmic bumping and a sensation of falling as Twilight descended the school’s staircases. Eventually, she stopped - and Norman felt his stomach drop as she quickly pulled her skirt and panties down to the floor.

Twilight lifted her panties, holding the sodden garment with two fingers as she placed it gingerly on a bench. Norman was tucked away in the folds of the fabric, still too small to be noticed - even when he poked his head out to look at his surroundings.

The dizzying scale of the world around him made it hard to recognize the shapes that stood above him, but the towering walls around him soon resolved into familiar rows of purple lockers. This must be the girls’ locker room; it was similar to the boys’, but a bit cleaner.

“Cold shower,” muttered Twilight. “Whether that spontaneous orgasm was magical or not, hopefully a cold shower will-”

A door opened nearby - or, from Norman’s perspective, very far away. Before Twilight could do anything to cover her below-the-waist nudity, Rainbow Dash entered the locker room. “Hey, Twilight!” she said - and then she noticed the state her friend was in. “Just hanging around with your pussy out, huh?”

“Yeah,” sighed Twilight, too burned out to have much of a reaction. “That’s me. Twilight Sparkle, hanging out in the smelly locker room with my pussy completely out.” She sat down on the bench, making the ground under Norman shake.

“Cool,” said Rainbow Dash. “Oh hey, I got that group text, did you sort out that magic thing?”

“Not really,” said Twilight. “But I think I can figure it out on my own. Right now I’m just here to take a shower.”

“All right, cool,” said Rainbow Dash. “I’m just getting changed for track practice. You might wanna make that shower quick - the rest of the track team girls are gonna be in here in like ten minutes, and… I haven’t known you that long, but you don’t seem like the kind of girl who’s super casual about being seen naked.”

“Yeah, I’m not,” said Twilight. “Thanks for the tip.”

Rainbow Dash set a gym bag down on the bench, then took out a few articles of clothing… including a sports bra. Norman weighed his options; he could stick with Twilight, but a little novelty might make today even more special. While the girls were looking away from him, he crawled out from within Twilight’s musky panties and into Rainbow Dash’s clean gray sports bra, tucking himself into a fold of the fabric.

Twilight promptly pulled off her shirt and bra and walked out of sight. Norman craned his neck, trying to see into the showers, but the angle was impossible - and, Norman supposed, watching her take a cold shower probably wouldn’t be that exciting.

As Norman was looking in Twilight’s general direction, listening to the sound of the shower, he felt himself being jerked upwards. He grabbed onto the bra’s fabric for dear life, managing to stay in place until Rainbow Dash pulled the sports bra over her head. As the fabric conformed to the shape of her body, it trapped Norman, pressing him against the soft blue flesh of Dash’s left breast.

Unknowingly taking Norman with her, Rainbow Dash left the locker room. Her breasts weren’t the biggest in Canterlot High, but they were big enough to bounce ever so slightly when Rainbow Dash walked. The bra held them in place well enough, but even that little bit of jiggle was a pleasantly bumpy ride for Norman.

Being pinned against a giant boob wasn’t quite as intense as being inside a girl’s panties. The scent of Rainbow Dash’s skin was pleasant, but not overpowering like the fragrance of Twilight’s womanhood. Norman felt around with one arm, and discovered a spongy protrusion that had to be Dash’s big blue nipple. He ran his hands over the bumpy flesh - until a set of giant fingers pressed against his back, making him freeze in panic. Luckily, Dash didn’t press too hard, and the soft boob on the other side of his body cushioned him.

“Damn itchy boob,” mumbled Dash. Norman decided to cool it for a while - and as he lay motionless against her skin, he felt the sun suddenly hit his back. Even through the bra and the T-shirt Dash was wearing, the sunlight was still pleasantly warm. He didn’t have long to enjoy it, though, before Rainbow Dash started to jog in the direction of the track.

The gentle bumping rhythm of Dash’s walking pace was replaced by a continuous, intense jostling. Norman felt himself slipping downward, and he reached out to grab onto the nearby nipple, halting his descent. He rubbed the sensitive skin, and he heard Rainbow Dash’s breathing grow slightly deeper. She didn’t seem to realize she was being touched, but it was definitely having an effect.

Arriving at the track, Dash exchanged some pleasantries with her coach and dropped to the ground, curling her body in a fast-paced set of sit-ups. Norman took the opportunity to stroke the skin beneath him, running his hand along the rim of the giant nipple and rhythmically moving his limbs. Soon, his efforts were rewarded with grunts and heavy breaths from the beautiful giantess. She didn’t seem to realize that anything was unusual, judging by the uninterrupted rhythm of her sit-ups; she must have assumed that her bra was just rubbing her skin a little more than usual.

“What’s wrong?” asked the voice of the track coach, a woman who Norman didn’t know. “Don’t tell me our star athlete is out of breath just from doing sit-ups!”

“Naw, I’m all right,” said Rainbow Dash, pausing at the bottom of a sit-up “Just… adjusting to the heat, I think.”

“Well, whatever kind of adjustment you need, make sure you make it before the next meet!” said the coach. “And, you know, stay hydrated and all that.”

Speaking of hydration, the heat was beginning to raise droplets of sweat on Rainbow Dash’s skin. The surface under Norman was starting to grow a little bit slick… and when Rainbow Dash resumed her sit-ups and lifted her body, the jolt knocked him loose. He slid down, beneath the underside of Dash’s boob… and with each rapid push-up he slid further, until his tiny body emerged from the bottom of Dash’s sports bra.

Norman tumbled down Rainbow Dash’s belly, rebounding off of smooth blue skin as he rolled downward. He was still concealed by Dash’s shirt, so there was no risk of getting caught… but he did risk tumbling onto the ground unless he could stop himself somewhere favorable. Luckily, his tumble was taking him to the waistband of Dash’s gym shorts, and when he hit it, he managed to snag it with both hands.

He tucked himself into the waistband, slipping into Rainbow Dash’s panties. It was dank and musty, even more so than Twilight’s had been at the start. Dash was already a little bit wet, it seemed; Norman’s work on her breast seemed to have had an effect. He wriggled his way down to her pussy, walking his feet down her wide, wet lips until he felt the smooth, slick surface of her clit against his cheek.

“Fuck,” muttered Rainbow Dash, shifting her legs awkwardly as she stood up, “Not usually this horny right after school…” The field was starting to fill up as the rest of the team arrived, boys and girls in t-shirts and shorts - which didn’t help diminish the arousal Dash was feeling. After a few words from the coach, Dash and a few other girls lined up around the track, dropping into starting position: one leg forward, one leg back, hands on the ground.

If she weren’t poised for a race, Rainbow Dash might have investigated the insistent and intensifying movement in her panties… but she wasn’t about to sabotage her start just because something was tickling her clit.

The coach yelled “go,” and the racers took off. It didn’t escape the team’s notice that she didn’t get as strong a start as she usually did. Her form was a little wobbly, her legs not quite doing what she wanted them to. Over the next few seconds, as her rapidly jostling body made Norman lose his grip on her pussy and bounce around inside her musty panties.

Norman struggled to regain his footing. Once he got accustomed to the rhythm of her pumping legs, he managed to jam his hands into her folds, gripping the slick flesh and bringing his face up to her clit once again. The thought of pleasuring Rainbow Dash while she ran, unaware of Norman’s presence, was too good to pass up - so he put everything he had into it, licking her clit and stroking it with his cheek, pumping his legs up and down to touch every inch of her dripping slit. He was soaked in Dash’s pussy juice now, so saturated that he could barely detect the scent that Twilight had left on him. He could hear the blood pumping to her cunt; she was close.

And out on the track, Rainbow Dash was faltering. For her, of course “faltering” meant being only slightly better than the other girls on the team, but it was still confounding. What was going on in her pussy? It was as if every motion of her legs was making her cunt rub up against itself, driving her arousal higher and higher. Usually she was intensely focused when she was running, totally in tune with her body, every muscle performing flawlessly. But now her cunt was betraying her, trying to make her cum in public.

Was it the sight of Twilight that was doing this to her? Twilight was a good-looking chick… and even though she hadn’t been in a great mood back in the locker room, seeing her bare ass had been a treat. But thinking about it now was a mistake; the thought of those smooth, naked purple cheeks filled her mind with almost as much arousal as her body was feeling. She nearly stumbled, biting her lip, realizing now that an orgasm was inevitable.

In her panties, Norman was sweating, soaking in fluid, grinding his body against her slit. Her clit pulsed against his face as tension built in her womanhood, and that pulse grew faster and harder until it became a flood of release.

Dash stumbled, meandering off the track and collapsing to her knees with a groan. As the rest of the girls ran onward - a couple casting a glance backward at their teammate - Dash fell onto her side, quivering on the grass as her orgasm ran its course. She was still confused, her mind swirling with questions, but there was nothing she could do about it now - she was writhing on the ground, coming her brains out, and all she could do was try and make as little noise as possible until her pussy calmed down.

“Rainbow Dash, are you all right?” asked the coach, leaning down over the poor girl.

Dash turned her face downward, trying to hide her blushing cheeks as the last of the climax shook her hips. Once she’d recovered enough to speak, she looked up at the coach, muttering weakly. “Uh, I think maybe I landed on my ankle wrong,” she lied. “Is it okay if I skip practice today? It feels like I should go easy on it.”

“Well,” said the coach, reaching down a hand to help her up, “No one takes running more seriously than you, Dash, so if you think you should take it easy, you’re probably right. Run along, I’ll see you next time.”

Dash wanted to run back to the school building, to escape the site of her embarrassment, but she faked a mild limp to sell her story of a twisted ankle. Lucky for her, Norman wasn’t giving her any trouble; making a giant girl cum wasn’t easy, and he needed a breather
