Fluttershy sat quietly on the neatly tucked blue night sky covers of Twilight’s bed, distracting herself with the continuous thundering downpour pattering noisily on the window pane as Twilight made final preparations for the spell.
Twilight glanced up from her work a moment and caught Fluttershy’s worried eyes. Sighing, she walked over until she was face to face. “You don’t have to do this Fluttershy. I can just find any old stallion to do it. I just thought it might be… fun.”
“N-no, it’s just…how will it feel?” Fluttershy asked, failing to conceal her emotion.
Twilight put on her best reassuring smile. “I’m 99.9% sure you won’t feel any pain, and once the spell is finished, I promise nothing bad will happen to it.”
“Well, alright then. I think I’ll be okay,” said Fluttershy, slightly more relieved.
A few minutes later, everything was ready, and with a shimmering glow of magenta, Twilight shut and locked the door and closed the curtains. “If you want to stop at any point, just tell me and I’ll change everything back,” she said, receiving the tiniest nod from Fluttershy. “You remember the procedure, right?”
“Yes,” Fluttershy whispered, blushing. Her erection was already poking out, and she rubbed it until it was fully revealed.
“Aright then, let’s begin.” Twilight took one last glimpse at the spell and her horn shone its bright colors, sparkling and teeming with magic. From the mass of light, a stray ray cast out and enveloped Fluttershy. There was a flash, and the light faded. Twilight gaped, fascinated.
“Did it work? I don’t want to look,” Fluttershy squealed.
Twilight's eyes remained glued on the sight. “Oh, it worked. See for yourself."
Fluttershy unclenched her eyes, and slowly, hesitantly, lowered her gaze to see her bare crotch and a long pink cock... no, her cock lying separate from her on the bed. She jumped away in shock, and the bounce of the bed sent the appendage flying into the air.
Twilight reacted quickly and caught it with her magic, bringing it down to her hooves. "That would have been painful. Be more careful with your penis."
"I... I can feel you touching me. It's... strange." Fluttershy was blushing a burning hot red now.
Twilight grinned. "Good, that means it worked. How about we see what else is possible in this state?"
"Um, let me see it first, please. If you would, that is."
Twilight just kept smiling. "Of course." She levitated the cock back to Fluttershy, giving it a teasing squeeze before placing it in her hooves.
Fluttershy buckled a little, then stared at it in her hooves, examining it and turning it over. It was rock hard in her grasp. An idea came to mind. She blushed. "Would it be okay if I-"
Twilight had a million guesses as to how that sentence could end when she cut her off. "Fluttershy, it's your penis. Do whatever you want. Just don't forget I want to experiment a little myself afterwards."
Staring intently at the throbbing, flaring cock for another moment, teasing herself her own gentle touch, Fluttershy was overcome with desire. The warm length was plunged down her throat, and she sucked and massaged herself with her tongue in all the right places, collapsing over the bed. Her hips rocked as she rhythmically pumped in and out of her eager maw, making muffled moans around her member.
At the sexy sight and sounds of Fluttershy pleasuring herself sprawled out over her bed, Twilight's hoof almost subconsciously moved down between her legs. "Oh, Fluttershy..." she moaned
Fluttershy was in heaven at the mercy of her own lustfulness. Her noises grew louder as her wet, saliva coated cock slid faster and faster, in and out.
Twilight had an idea of her own. "Here, try this." She surrounded Fluttershy's penis in her telekinetic field, and started twisting it in her mouth as it was pumped. Fluttershy screamed into her cock at the newfound experience. Just as it was about to be too much for the yellow Pegasus to handle, Twilight pulled it out, and Fluttershy lay there, panting.
"So. Good. Please. Don't. Stop." Fluttershy gasped between breaths, exasperated.
Twilight grinned a sly grin. "Like I said, I need to collect more data." She jumped up on the bed with Fluttershy, bringing the lovely appendage with her. "Have you ever done it with a mare before?" asked Twilight.
Fluttershy nibbled the end of her hoof, gazing at her cock, before replying "Only once. It was a long time ago."
"This should be interesting for you then." Twilight spread apart her legs on the bed, and the hovering cock pulsed with eagerness. She lowered it to her lower lips, gently flicking the tip back and forth a few times before slowly sliding it inside, eliciting a shudder from Fluttershy. The pair bucked their hips while Twilight found a steady tempo.
"Unh, Twilight, yes!"
Reaching her hooves round Fluttershy and pulling her closer, Twilight engaged in a deep, passionate kiss. She was surprised when Fluttershy kissed back with much greater vigor and dominance. Twilight sped her magic, and Fluttershy bit down on her hair as she struggled to last. Again, using her idea from before, Twilight rotated the cock while she thrust it back and forth. Now both she and Fluttershy were screaming in bliss. Things continued to speed up until Twilight was moving the cock at a blazing speed that would have been impossible if it were still attached to Fluttershy.
Fluttershy squealed out. "I'm gonna... cum!"
With one final deep thrust, Fluttershy's penis was pushed down, hitting right on Twilight's g-spot.
"I'm cumming!" they screamed in unison.
A few minutes later, the both of them were flat on the bed, completely spent, when Fluttershy finally asked, "Can you uh... put my penis back now?"
"Tomorrow. It's late, and I still have much more experimenting to do, so let's just get some rest for now."
"Alright. I love you Twilight."
"Love you too, Shy"
The lights went off, and the couple cuddled in the bed, with Fluttershy's penis resting on the pillow between them.
Author's Note
Strange, no? I certainly haven't seen anything like it on this site before. Hopefully you liked it. I'll admit it was rushed since I don't have much time on my hands, but really, I just wanted to get the idea of it across. And no, that ridiculous alliteration was actually completely accidental. Darn it, I'm doing it again.
