Spike screamed at the top of his lung as he fell out of the bed, luckily taking the blanket he was under with him. He pushed himself towards the corner of the room as he began to take rapid shallow breaths.

“W-what just happened?” Spike asks as he looks once more at Twilight, who was already getting up and walking over to him.

“Um, Spike? Are you alright? What just happened to you?” Twilight asks as she presses a hand against his head, and felt he had somehow heated up again. “Oh boy, your temperature is even higher now… Maybe whatever just happened was a heat induced Hallucination?”

“M-maybe… Twilight, what is wrong with me?” Spike asks as he keeps his eyes on her while she tries to figure out an answer, only for that to get cut off with Spike saying, “...You don’t know, do you”, causing any ideas she had about the situation to fade out of her mind.

“Sorry to say Spike, but you're right, I have no clue what’s wrong- Oh boy” She says as she feels Spike's temperature rise again, causing him to wince once more and forcing her to rile back her hand to keep it from getting burned. “Ok, Spike, I think you need to stop talking, something about that is making this worse”

“A-alright” Spike says as Twilight gets up and tries to get an idea on what was happening and how to fix it. “Did I cause the change in the world? I-is it even an actual change? No, it has to be!” Spike thinks to himself as Twilight sits down on the bed, and pats it to let him know she wants him to sit beside her.

Spike gets up and walks over towards her, blanket in hand to cover his lower half, as he feels the bizarre astonishment of being taller than Twilight by her just sitting down instead of standing. He sits down beside her as he felt himself sweating now from the heat inside himself, which definitely didn’t feel like any fever he normally would have. Twilight noticed this as she pulled a bag of ice from the freezer and placed it onto his scales, where it quickly began to melt. Spike could feel the cold, wet bag on his back, but it was still just on top of his overheating body, and not cooling that part of him down.

“Ok, this may just be a weird dragon thing, like the molt or the dragon lords call…” Twilight begins as she tries to help Spike realize what it might be. “Maybe this is some second type of change, like the molt, into adulthood… Like a change that functions more to help you mate then just helping you get your wings-”

“WHOA WHOA WHOA-” Spike begins as he shakes his arms and body at what she just said. “Mating? Tha-... Is this really not going to stop until I have sex?”

Twilight starts to explain that isn’t how puberty works, but feels her thoughts change, warping into the knowledge that whatever was happening to Spike functioned like that. “Y-ya, pretty much… I-I would have described it a b-bit more tactfully…” She answers, trying to hold back a blush from awkwardness as she heard Spike whimper again as she could feel heat coming off of his body now, causing the plastic of the bag to begin melting too

Spike groans as he realizes that Twilight was going to either ‘help him out’ like in the incestuous erotic novels she had in the library, or try and find someone willing to hook up with him just to help him cool down. He then began to wonder back to how she and him now looked, as it definitely seemed like they had both been changed by something… right as he had asked if the creatures of their world were like… humans…

Spike’s eyes widened as he remembered that he had asked if what Twilight said was a joke, even though it sounded like something Pinky would have said, and she said it had been. That was odd, but it could be explained as coincidence. Same with her having no clue about what was affecting him. But the last one, his questioning about how this worked, was just a response out of panic! Puberty for Twilight hadn’t stopped because she had sax, because she didn’t! Yet she agreed with what he said! If not for the risk of burning up inside even more, he would have tested something that could 100% not be a coincidence to prove that he had caused the changes, but for now, he knew that this all had to be connected to him in some way.

Twilight, for her part, was also stuck in a conundrum of her own. Not about any changes, no no no, but on how to help Spike. Sure, she could just spend a few days to find someone in town willing to fuck a superheated dragon, but by then how hot would Spike have gotten? The next option was trying to help her himself, which was a mess of incest, and the thought of getting addicted to hic cock or cum was horrifying to the princess. Still, it was the only option she had, cause having him mastrabate wouldn’t help, it has to be sex after all.

The princess of friendship grabbed the blanket’s edge and uncovered Spike's lower half, revealing a good sized sheath to her, as Spike was pulled from his mind back to reality, now focusing on Twilight.

“Y-you don’t n-need to do this” He says, trying to make Twilight stop with his seeming ‘powers’, only to see them fail when she replies.

“I-I fear I do…” Twilight says with a gulp as her horn lights up and magic surrounds his balls first to help get his cock out.

She has her magic massage them as best she can while trying to look away as she hears Spike panting even more, though this time, hopefully from pleasure. He leans back a bit as her magic goes at it in a precise way, but he could tell that whatever practice Twilight had for this was not practical. He moved a bit back as the magic followed, slowly repeating the same pattern over and over again. The tip of his cock began to push out of its sheath as Twilight looked back at him, gulping and blushing before turning back around when she saw she had made progress.

“T-Twilight will stop n-now” Spike whispers before a moan pushed up and out of his throat, as he saw Twilight keep going despite this.

The magic kept up the same pace and pattern, which if this hadn’t been Spike’s first time, would have not done much to get him horny after a certain point. But it was, so it was the most stimulating touch he had ever felt down there. His cock kept pushing out slowly but surely until finally his knot pushed out with an audible pop, causing Twilight to turn back. They were both surprised to see his cock was a full foot long, not too unusual for a stallion, but bigger than Spike had been before, and more than Twilight was hoping it to be.

Twilight stared at his cock for a few moments before her magic covered it and began to move up and down on his cock robotically, pumping it like a milling machine would. This still caused Spike to moan loudly as he fell on his back and from there he wouldn’t move, letting Twilight take control of his first time.

Twilight watched her magic work, biting her lip as she tried to look away, but she couldn’t force herself from watching his cock as he kept panting from the heat and pleasure. She felt herself move a bit closer, and had to grab her own hand to keep her from grabbing his cock in her own hand, not wanting to risk it. She kept the pumping and ball massaging going at the same time for a while, though she and Spike quickly lost track of time. Eventually, Spike let out a rose of a moan as a jet of white fire poured out of his mouth as he came, his load being oddly small compared to the loads Twilight had read about, only causing a small line or two on the sheets.

“You better Spike?” Twilight asks as she removes her magic from him, already feeling no heat coming off of his body.

“Y-ya… Thanks Twilight” He says as he sits up, realizing the heat that filled his body was gone once more, and let out a sigh or relief, if only for a moment.

Author's Note

If you have any suggestions on what spike should do next let me know. Here is how the Powers work roughly.

1- Whenever Spike asks a yes or no question, the answer becomes yes, and reality changes to match that.

2- When ever his powers are used his body heats up. This can only be undone by sex. It goes by time activated, not individual questions. So 5 questions at once heats himself up the same as 1 question alone, as long as he doesn't pause when speaking.

3- He can't use his powers to undo these rules, only add to them.

I am also looking for Beta Readers, so let me know if you are interested in that.
