Later that night, after Thorax had finished making dinner and they had eaten, Thorax asked Eclipse Seeker something he had been thinking for a little while.

"How did you do it?" he asked.

"Do what?" Eclipse Seeker asked.

"Have sex with yourself?" Thorax asked. "How did that work?" Eclipse Seeker lightly blushed.

"Well, I got an erection, but not too hard, and I had to angle Sunburst's shaft towards Starlight's vagina, and started inserting it," Eclipse Seeker said. "After that, it was simple. Just keep pumping. I've masterbaited as Sunburst and Starlight before, but I've never experienced an orgasm that intense." By the end, both Eclipse Seeker and Thorax were blushing.

"That must have been...interesting," Thorax said. Eclipse Seeker nodded. "So, did you figure out whatever it was you were trying to figure out?" Eclipse Seeker nodded.

"Yes. I think the fusion spell was never completed," he said.

"It was never finished?" Thorax asked.

"Yes," Eclipse Seeker said. "That or whoever made the spell didn't do it properly. Either way, it'll be exciting to make it right."

"Yeah it would," Thorax said. "Who knows, you might get some kind of title, or reward or something."

"Yeah, that could happen," Eclipse Seeker said. "But I don't really care for that."

"Let me guess, your more in it for the learning possibilities?" Thorax asked. Eclipse Seeker nodded.

"You bet," he said. "Of course, I better figure out other stuff while fused. Actually, do you mind if I go do that?" Thorax shook his head.

"Go do it," he said. "It could better Equestria." Eclipse Seeker grinned.

"You're right about that," he said. "It could. Surprisingly, for the next few days, Eclipse Seeker mostly stayed in his room, figuring out equations and problems that could help better Equestria. On the fourth day, they were eating dinner again, and Eclipse Seeker was talking about how he had figured out a spell that would help create more food, and specifically creating vegetation in a desert.

"It all had to do with the sun and water," he was saying.

"Nice," Thorax said. "This will be able to help the changling kingdom!"

"That's in part why I did it!" Eclipse Seeker said. "The only thing I haven't figured out yet is how to fix the fusion spell." Thorax nodded.

"And don't you defuse tomorrow?" he asked. Eclipse Seeker nodded.

"I have until tomorrow to solve it," he said. "Although, if I don't figure it out by then, the three way fusion might be able to solve it."

"That would be cool," Thorax said. "Oh, by the way, Cadence and Shining Armor are going to be here in a few minutes." Eclipse Seeker gasped.

"Why?" he asked.

"They wanted to see how this fusion was going, and they wanted to see all of your new theories and solved problems," Thorax said.

"I have to get dressed then!" Eclipse Seeker said. "How soon will they be here?" As she finished saying that, there was a knock on the door.

"Now," Thorax said, standing up and starting to walk towards the door. "And don't worry about dressing up, it's a casual meeting." He opened the door.

"Hello!" Cadence exclaimed as she walked in. She and Shining Armor stared at Eclipse Seeker as they walked in.

"So this is what you look like," Shining Armor said with a grin. "Nice."

"So, Thorax says you managed to figure out a ton problems that Equestria has?" Cadence asked. "And that you've named yourself Eclipse Seeker?" Eclipse Seeker nodded.

"Not only that, but several way's to help out the changling kingdom repair itself," he said.

"And all because of this spell," Shining Armor said. "Nice. Hey, maybe you could figure out something that will help the Royal Guards recruits train better?" Eclipse Seeker nodded.

"Sure, I'll still have both Sunburst's and Starlight's intelligence tomorrow when we do the three way fusion," Eclipse Seeker said.

"Speaking of which," Cadence said with a grin. "Did you ever have that fusion sex?" Eclipse Seeker blushed.

"Yes," he said. "I'd rather not tell you about it right now, so maybe I can come by tomorrow and tell you about it?" Cadence nodded.

"Sure," she said. "That sounds good."

"Thank you," Eclipse Seeker said. "Now, what else specifically did you want to know?"

"You have both sets of privates?" Shining Armor asked.

"Yes," Eclipse Seeker said. "I wouldn't be able to have sex with myself otherwise. Now, sit down. I can tell you more about the sp-." Suddenly Eclipse Seeker twitched, and realization dawned on his face. "It's happening." He twitched again and turned around, heading towards the living room. Just as he got to the door, he started to spasm and fell to the ground. Thorax knew that, for whatever reason, the fusion spell needed to be undone. Thorax ran towards Eclipse Seeker and was able to pull his shirt off before Eclipse Seeker teleported them off, and in another flash of light, he had defused back into Sunburst and Starlight. Cadence covered Shining Armor's eyes because of Sunburst and Starlight being naked, and Thorax started dragging them into the living room.

Author's Note

The ending was rather fast, I know. And there is a reason why they needed to defuse early. But I hopped you liked the chapter, and the next one will be released soon.
