You can't help but groan, continuing to put the books back up onto the shelves. You regret throwing that party last night. Spike SOMEHOW convinced you to throw it while Twilight was out. You could've been good and said no, but NOOO! You had to prove to Spike you weren't scared of what Twilight would do.

Of course, Spike wimped out when Twilight got home and he ran off somewhere. Presumably to SugarCube Corner or to Rarity's. You could hear footsteps behind you, which kinda scared you and you started to quickly stack books.

"What're you doing? I said alphabetical and by genre! Not random!" She said, taking off some of the books that you just stacked up. As the books levitated above you, you sighed and said. "Twilight look, I'm sorry I threw that party and trashed the castle. Really, I am!"

Twilight just looked at you and sighed. "Well, I guess it's not your fault. I was gone for a while..." She thought for a moment, then gave you a warm smile. "Oh ok, you can stop." To this, you jumped up in joy. "Woohoo!" You ran over to Twilight and hugged her, lifting her off her feet some in the process. "Thank you! I promise you won't regret letting me go!"

Twilight giggled some and hugged back. "Hey, wanna help me test out some new spells?" You looked at her, a bit confused. "New spells? Where'd you find new spells?"

Twilight led you up to the bedroom, which also had books in it, presumably story books, though some of them were apparently spell books. "Well, Celestia recently sent me new spell books, with spells that I didn't even know existed! So since Spike isn't around I was wondering if you wanted to test them with me."

To this, you're mind raced. Spells that TWILIGHT'S never heard of?! These must be Royal Class spells or something! And you didn't even know those existed! "Sure! I'd love to!" You said, jumping onto the bed with a soft 'plop.' "What's first on the list?"

Twilight opened one of the books, stating the title before testing it. "Iris Changing Spell!" Her horn glowed a familiar violet and she shot a small beam at you. Nothing happened, and you looked confused until Twilight levitated a mirror to you. You gasped slightly, you're once (You're eye color) eyes were now a turquoise!

"Awesome! What's next?" You asked, eager to try out more spells. She undid the spell before moving on the the next spell, stating. "Deja Vu Spell!" She said, her horn once again glowed violet. "Awesome! What does it do?" You asked. Her horn glowed brighter and brighter until a thin beam shot at your head.

"It does that!" She said, smiling. You looked confused and asked. "Does what?" Once again, she charged up and shot another thin beam at your head. "That!" She said again. And again, you looked confused. "Does what?"

This time, she only giggled. "Nothing, I'll have to work on that one." Upon flipping to the next page, a small slip of folded paper fell out. Twilight looked down at the paper and picked it up. Upon unfolding it, her eyes went wide and her cheeks turned a deep shade of red.

"Twilight? Something wrong?" You asked, curious about the paper. She suddenly snapped out of it, saying. "U-Um...i-it's nothing!" The stuttering only made you even more curious. Twilight looked at the paper, then to you. "I-I think this may have gotten mixed up wight he rest of the spells."

You finally got up and looked over at the paper. Now it was your turn to blush. It was titled Futanari Spell/Mare Cock Spell. You coughed uncomfortably and went back to the bed, taking a seat. "U-Um...you can test it in the other room if you'd like Twi. I'll wait here."

Twilight looked at you, a blush still stained on her cheeks. She had to admit, she was curious about the spell. She nodded and ran into the other room, turning a corner. This was the ONE time she wishes there were doors inside the castle.

She gulped and slowly activated the spell, her horn glowed and soon enough her lower body started to glow as well. It glowed brighter and brighter. Then suddenly, the light vanished. She looked down and her eyes widened in shock. There stood an 8 inch flaccid cock. Her womanhood was still there, there was just...something else there too.

Her eyes flashed a bit, and she felt...different. She looked around the corner at you. You were currently writing a letter to Celestia, thanking her for the spells.

Twilight bit her lip. Her cock started to grow in size while staring at you. She started to notice she her hands reached out her her cock and she started to slowly rub her cock. Her soft hands went up and down her large shaft as it grew in size.

She couldn't help it. She needed something, anything to relieve the pent up feeling she felt. And you happened to be around so...

She slowly walked up to you, giving you a hug from behind. Her cock stood between your legs so you didn't notice it yet. "Oh, hey Twi. Did uh...the spell work?" You asked, sounding a bit embarrassed. You were embarrassed because A. You were talking about a Girl Cock Spell. And B. She was hugging you.

She giggled softly and nodded, that that you could tell since you couldn't see her. "Yep, it worked amazingly. Wanna see it?~" She asked. You could tell something was off about her voice. It was filled with what you could only describe as lust.

Hearing her question, you turned around slowly. "'See it?' See wha--" You're eyes widened, now knowing fully well what she was talking about. There, between Twilight's legs stood a 10 inch cock, and it didn't even look fully erect!

Now, while thinking to yourself you didn't notice that you were staring at her cock the whole time. This caused her to blush and ask. "D-Do you like it?" Hearing this, you snap out of your zoning state.

"W-What?! N-No! I mean yes!--I MEAN NO!!!" You were honest to Celestia confused at this point. Twilight was nowhere near ugly, intact she was beautiful. You weren't gay but for some reason her having a cock still turned you on...You started to stare again, this time letting out a gulp.

Before she could say more, you snapped out of your zoning state again. "W-Why are you showing me that?!" She just smiled and answered. "Because...well...I kinda want you to...w-well..." She smiled sheepishly, thrusting her hips ever so slightly to try to get you to understand her meaning.

After a few moments of pondering, you knew exactly what she wanted. You tried your best to think of a way out of this. You weren't gay, but the cock she had turned you on! If you said no, she may think that you think that she's ugly, which definitely is not the case!

After a few more minutes of thinking, you sighed in defeat. "A-Alright...what you want me to do?" Hearing this, she smiled and walked up to you. "W-Well...Can you suck it?" She asked nervously.

For Twilight, she was being surprisingly forward about this! You gulp then nod, getting down onto your knees. You stare at the throbbing meat pole on your face, your hand reached for it and took hold of it. You gave it a few strokes, looking up at Twilight. "Y-You better not tell any pony about this..."

Once again, she smiled and put a hand on the back of your head softly. "Cross my heart, hope to fly! Stick a cupcake in my eye!" You slowly point the cock downward so you can get it in your mouth. "Here we go..." You think to yourself.

You slowly started to take the girl cock in your mouth, you felt it against your tongue as it pushed itself in your mouth. You shut your eyes tight, trying to take it in your throat. You could hear Twilight pant and moan softly, putting both her hand on your head softly. "Mmmnn~...Y-Yeah..." She moaned to herself.

Her moans slightly turned you on, you started to slowly bob your head on her cock. You swirled your tongue around the throbbing shaft, trying to please the futa pony. You could tell you were successful as she made slightly louder moans.

You felt her try to push your head forward, wanting to fit her whole cock in your mouth. You tried to push against her, knowing it wouldn't go all the way down. You're eyes widened, feeling her suddenly thrust forward and plunge her cock down your throat. You started to gag slightly, but you breathed through your nose and felt slightly better.

She only got rougher from there. She pulled out a bit, then thrusted back down your throat. She repeated this motion, over and over. It seemed like she wasn't gonna stop anytime soon. After about 8 minutes of nothing but her thrusting down your throat, you felt her cock throb more and more.

Her moans became louder and louder, her thrusts faster and rougher. Then, with one thrust, she came. You're eyes widened, feeling her shoot her hot sticky load right down your throat. You took it all, gulping down her seed as it seemed to have no end.

Finally though, she stopped cumming. She pulled out of your throat, and you coughed up a tiny bit of cum. You looked up at her, wiping your eyes, which became watery.

Suddenly though, everything became purple and sparkly. You felt yourself get lifted off the ground and onto the bed. You couldn't move, the only thing you could move was your eyes, and your eyes caught a glimpse of something you couldn't believe.

After all that, she was STILL hard! Her cock now a full 12 inches stood at attention proudly between her legs. She climbed up onto the bed, you were pinned down by her magic so you couldn't move.

"S-Sorry Anon, but I can't help it! I-I have to do this! The faster the better right?!" She said, still Twilight, but not the same. You felt the magic start to unbutton your pants and pull them off, along with your boxers.

You felt her force you onto your hands and knees, what scared you the most about this was that you couldn't see what she was doing. She put two fingers in her mouth and licked them, and sucked them slightly.

After a minute of licking, she took her fingers out of her mouth and lowered them to your asshole, pushing them inside. "Eep!" You accidentally went, not expecting the wet fingers. She continued to finger you, spreading her fingers some to widen your back entrance.

This went on for 2 minutes. You didn't notice it at first, but after the first 30 seconds, you started to moan softly under your breath. After the 2 minutes, she took her fingers out.

She then got into position. She put her hands to your waist, firmly holding you in place, despite already being held in place by her magic. Her cock prodded your ass, almost teasing it as it pushed against your asshole, but then backed away.

After a few prods, she pushed herself inside, managing to fit the first 2 inches in before letting you rest. "You ok?" She asked, a bit concerned. You bit your lip, nodding slightly. "Y-Yeah. I-I'm ok. You can keep going."

You just wanted to get this over with so that Twilight will be back to normal. She nodded and started to push again, struggling to fit it inside your tight virgin asshole. She grunted between her moans, slowly citing inch after throbbing inch inside your ass.

After a while of pushing, she finally fit all 12 inches in your ass. It hurt slightly, but mostly you just felt...full. You felt her pull out of your ass, until only the head was in, then she thrusted back inside, causing both of you to moan out.

She repeated this rhythm. At first it was slow, but it slowly turned into a steady pace of thrusting. She let out a moan each time she thrusted, and you let out a moan each time you were thrusted into.

"T-Twi! K-Keep going!" You managed to say between her thrusts. She nodded and pushed you onto yours belly. She wrapped her arms around you and started to pound your tight ass. Each thrust bounced the bed under you, and you were doing most of the moaning!

You couldn't help it anymore, you loved her cock. You loved the feeling of it when it thrusted into you. You loved how her hips smacked against your ass whenever she thrusted deep inside you.

"O-Oh sweet Celestia Anon! Y-You're so tight! I-I-I'm about to cum!" She yelled out, the thrusting could now only be described as pounding. Her wings spread and she bit her lip, pounding harder and harder until...

"O-OH ANON!!!" She came in your ass. She filled you up with her hot seed, overflowing it. It would have poured out of your ass, but her cock acted as a plug, preventing the cum from escaping.

You came as well, you could feel your semen shoot out and onto the side of your leg.

You panted softly, with the beautiful alicorn above you, her cock still in your ass. You could both hear and feel her pant into your ear. Her hot breath against your ear making you shudder ever so slightly. After a few minutes of panting and resting, you decided to speak.

"T-That was fun...I-I should test out spells with you more often..." You managed to pant out, trying your best to keep yourself from drooling. Though you were unaware of a certain cyan blue pegasus out the window who just saw the whole thing.

Author's Note

Hope you all enjoyed it! I'm also taking a vote for the next pony to fuck you all next time! For now however, I'm only doing the mane six. Apologies, but I feel that I should get them out of the way before moving on to someone else. Next pony has been decided! Next up is...
