Sci-Twi’s Mystery Machine of Randomness

Rainbow dashed through the halls of CHS with a wide grin on her face.

“This is so cool, I never thought I would be able to become invisible. And I know what I want to do first.”

She stopped in front of the door leading to the men’s showers, a big smile on her face.
Rainbow entered the men’s changing room, and then stood in a corner, waiting patiently.
The soccer practice had ended just a few minutes ago, and she could see the steam of the hot water coming from the showers.
In just a couple minutes, the entire soccer team got out of the showers.
She admired the muscled, wet bodies of her classmates, and as they slowly undressed to their underwear, Rainbow started to rub herself over her sport shorts, panting a little at the sight.
She normally wasn’t such a pervert, but the opportunity for this made her forget some of her inhibitions.
Suddenly, her eyes focused on a particularly large bulge in one of the boy’s underwear and smiled as she saw Soarin filling said underwear.
She had heard rumors of his apparent interest in her and knowing that a good piece of dick desired her filled her with pride.

Sadly, her little show ended quickly as the boys got dressed and started to leave the changing room, but to her surprise, Soarin stayed.
He was looking at something inside his locker, so she got closer to him so she could see.
Soarin pulled out a photo from his locker, looking at it with lust.
Rainbow got close enough to see that it was a picture of her getting out of the shower, a towel barely covering the front of her hips, her breast on full display, and the curve of her ass teasing what was behind. She recognized it as a picture that Sunset had taken of her during her time as a bully, with the intention of selling it to the male students. She though that she had managed to destroy all the copies, but apparently Soarin managed to hold onto the last one.
The fact that he apparently didn’t make more copies made her forgive him, but more importantly; this confirmed the rumors!

“Oh Dash.”

Rainbow panic a little, thinking that she got caught, but Soarin hadn’t noticed her. Instead, he took off his underwear and started to stroke his dick while looking at her picture.
Rainbow looked as his member slowly grew and hardened, reaching an impressive size.
She was impressed, but what was making her more wet was the fact that it was growing because of her. She always loved that people appreciated her awesomeness, but this was a completely different type of ‘appreciation’.
Rainbow looked in trance as Soarin stroked himself at her image, feeling the heat between her legs increasing. She started to caress her pussy directly, even digging a finger in, but it wasn’t enough. She needed that dick inside her.

‘Damn, I can’t just tell him to fuck me while invisible, he will freak out thinking I’m a ghost’

Suddenly, Rainbow had an idea, and quickly started undressing herself.

Soarin looked at the curves of the Rainbow in the photo, wishing he could feel them for real.
He had thought about asking her out someday, but rumor said she had the hots for Spitfire, and after the whole fiasco that gave him the picture to begin with, he was sure Rainbow didn’t look for men in the faculty.
Suddenly, his vision was obstructed by what he guessed was a towel.
The first thought that crossed his mind was that one of his classmates decided to pull a prank on him, but the seductive voice in his ear made him both cold with fear and hot with arousal.

“Looks like I have a very dedicated fan.”

“R-Rainbow?” Soarin tried to hide the picture, but she took it from his hand.

“Even taken by surprise I manage to look awesomely sexy.”

Soarin felt his heart skip a beat as Rainbow leaned on him, and he could feel her bare skin against his, her hard nipples poking him from behind.

“But tell me, wouldn’t be better to feel instead of seeing?”

Soarin could feel her hands in his chest, moving lower while caressing every curve of his muscles, until they got extremely close to his hard member.
The anticipation for her touch in that area maintained him hard, not like he wouldn’t be hard with Rainbow seducing him while pressed naked against him.

“Tell me, what part of me is your favorite?” Rainbow asked, rubbing her chest along the upper part of Soarin’s back, making answering her more difficult.

“You- Your ass.”

“Really? Why’s that exactly?”

“It’s well toned, just the right size, and-” Soarin stopped as Rainbow guided his hands to her ass, planting his palms against her glutes.

“And? Keep going.”

“It’s smooth, and soft enough to dig your fingers a little,” he responded as he gave it a squeeze before moving his hands over it, savoring the feeling of what he considered the best ass in the school.
Rainbow gave a little laugh. “Well, I’m still deciding, but I have a big contender for my favorite part of your body,” she said while dragging a finger over his length, making him sigh with arousal.
Soarin felt Rainbow tightening the towel in his head, making sure he couldn’t see.

“You have seen enough; I want you to just feel,” whispered Rainbow in his ear, turning him around and leaning on him.

He could feel their chests pushing against each other, but the most notable sensation was that of his dick being trapped between Rainbow’s legs. He could feel the wetness of her pussy dripping over his member, arousing him to no end.
Rainbow started moving her hips slowly, covering his dick with her wetness, making him nice and lubricated.

“Do you believe this is a dream?” asked Rainbow.

“If it is, I don’t want to wake up.”

Rainbow grabbed him by the ass, giving a good squeeze, and sat him in a bench in the center of the locker room.
Rainbow stood over his legs and guided the tip of his dick towards her pussy, giving little circling motions to tease him with the entrance inside of her.
Soarin grabbed her by the hips, wanting so bad to just force himself inside, but didn’t want to ruin the moment, so his hands started exploring her body.
The fact that he couldn’t see it made the action more engaging, he was building the image of Rainbow in his head with every touch of her skin and feel of her curves, and it was much better than her picture.
It didn’t take too long for him to find her chest and started massaging it with his hands.
Rainbow let out a low moan, and slowly lowered herself onto him, feeling his dick slowly filling her insides.
Soarin let out his own moan, louder than Dash’s, and continued the exploration of Rainbow’s body.

“Oh yeah, your dick is great,” said Rainbow once his dick was fully inside her. She started to do slow, circling motions like before, but then she took him by the shoulders and lifted herself up, only to go back down again.
She quickened the pace of her movements, starting to pant at the pleasure of being filled by Soarin’s dick.
Soarin himself was being lost in the pleasure, his hands stopping their wandering to just hold Rainbow by the sides, helping her ride him to his pleasure.
The rainbow haired girl leaned over towards Soarin and whispered in his ear again.

“Is this the most awesome ride you ever had?”

“Probably the best I will ever had.”

“Good, because I plan to make it memorable.”

Suddenly, the door to the locker room opened.
Soarin took off the towel in his head to see who had entered but his attention got redirected to the fact that Rainbow Dash wasn’t in front of him, but he could still feel himself inside her.

“Soarin!” called out a voice that again diverted his attention.

Both him and Rainbow looked to the side, seeing a wet, towel-clad Spitfire watching them with a kind-of annoyed look in her eyes.

“What are you doing here?” asked Soarin while Rainbow concentrated on being completely silent.

“Your friends told me you were staying here to masturbate, and I see they weren’t wrong.”

‘Wait, she can see his dick? Am I completely transparent?’ Rainbow wondered while Soarin tried to calm himself and give a response.

“Hehe, you got me.”

Rainbow tried to lift herself off him, but her pussy gave some resistance by clamping on him.
The movement didn’t go unnoticed, and Spitfire pointed at his member.

“Does it normally twitch so much?”

“Em… it’s just happy to see you?” he responded with a smile.

“I thought you were into Dash.”

“Yeah, but you-” Soarin could feel the invisible gaze of Rainbow warning him to choose his words carefully. “-are a close second?”

Spitfire raised an eyebrow, unamused.

“Charming.”

‘She sees this dick and it’s not the least bit interested? The rumors of her preferences must be true,’ thought Rainbow while looking at Spitfire’s form.
The towel barely reached form her breast to her hips, teasing her slender waist, and the shape of the towel around her chest was also alluring to her eyes.
She was a close second to her. And she would take her too when the time was right.

“I came here to speak to you about your performance in todays practice and some strategies I wish to discuss for the coming matches.”

Soarin was about to object, but Rainbow gave him an invisible mischievous smile, and slowly lowered herself onto him again.

“Mmmm, sure. Let’s start.”

“Don’t you want to cover yourself first?”

Rainbow continued moving slowly to not catch to much attention from Spitfire.

“It’s not like I have something to hide that you can’t see now.”

Spitfire shrugged. “As you wish.”

Rainbow had to give credit to Soarin, the guy was maintaining the conversation with Spitfire while having her riding his dick.
Having sex practically in the face of Spitfire without her realizing it was a bizarre and very hot experience, making her desire more.
Rainbow started rubbing her clit while her other hand grabbed her chest, trying to quell the arousal she was feeling. But it wasn’t enough.
Her movements became quicker and more irregular, but fortunately Spitfire seemed too absorbed in the conversation to notice it.

Soarin’s fingers were starting to dig into his seat, trying very hard to maintain his composure.
Never in his entire life he imagined the possibility of having sex in front of her captain with the school’s sports star, and having to maintain a straight face was driving him nuts.
He desperately wanted to just rut Rainbow then and there, and maybe even try and fuck Spitfire since she was there, he was screwed either way.

Suddenly, he felt teeth dig into his shoulder.

Rainbow bit Soarin in the shoulder to silence the moans she wanted so desperately to release and started to move more quickly.
She needed more, but she couldn’t even get him completely inside without making a clap against his legs, giving away their act, but she was starting to care less and less of the consequences.
Let Spitfire see, maybe she could convince her to join them.
She was so temptingly close to climax, but needed just a bit more speed, more force, more-

Spitfire gave a frustrated grunt, making Soarin and Rainbow froze in fear.

“Look, clearly your dick needs some release seeing how much it’s moving on its own, so sorry for interrupting. We can continue tomorrow.”

Spitfire walked away, returning to the girls changing room, leaving them alone once more.

“Great, now we can-” Rainbow was interrupted as Soarin lifted her up and slammed her against the lockers. “Oh shit.”

He started to slam into her with all the pent-up tension and arousal he had been holding during the entire conversation, making them both scream and moan without a care if Spitfire could still hear them.
Rainbow clawed at his back, trying to hold on and resist the pleasure to enjoy more of the moment, but it was impossible.
She bit Soarin one more time as she came, leaving a mark of her teeth as proof of the event.
Soarin came soon after with much more force than ever before, and had the strange show of seeing how his dick slowly filled the insides of Rainbow with his cum.
They both stayed still while their orgasms slowly faded, and finally Soarin pulled out of Rainbow to collapse into the bench, clearly spent from the ordeal.

“So… Are you going to tell why I can’t see you?” He asked, but there was no response. “Rainbow?”

Spitfire opened her locker, looking for her clothes to dress herself, when she felt a pair of hands grab her ass and squeeze it.

“I will claim you soon.” A voice whispered in her ear, and she turned around but saw nobody there.
She put her hand on her chest, feeling her heart racing, and her cheeks hot with her blush.

Rainbow exited the women’s changing room with a victory smile on her face, feeling completely satisfied with the results of her little escapade.
She started to wonder in what other ways she could use her invisibility when suddenly she was hit in the face with a pinch of makeup.

“So there you where darling.”

“Rarity? How did you see me?”

Rarity simply pointed at Rainbow’s hips, and the athlete saw that Soarins cum was still inside her, visible for everyone.
She uselessly tried to cover herself with her hands, but they were also completely transparent.

“Let’s get you to the bathrooms so you can clean yourself,” Said Applejack, appearing behind Rarity and taking Rainbow by the arm.

As the three of them walked through the corridor, Rarity leaned over to Rainbow.

“So, who was the lucky one?”

“Really Rarity? Now?” complained Applejack

“I can’t waste the opportunity for good gossip.”

“It was Soarin. He has it big,” responded Rainbow with a devilish smile.

“Oh, you have someone to compare to?”

“All of the soccer team.”

“Ohhh I will need details.”

Applejack gave an exasperated sigh.
