She'd prefer an actual woman but this will do for now.

Sunset gets confused as she hears the wheels of the travel bag. "Whats that?" You open the bag and Sunset can't help but burst out laughing seeing this thing. "Thats hilarious." She spanks its ass. "It will do until you build that harem." You're not sure you're charismatic enough to build a harem but you'll do your best.

You get curious. "So this thing is smaller then a regular ponys body. Is this as big as you used to be in Equestria?" She looks at it for a few seconds before shaking her head. "Put a neck, head and legs of proportionate size on that thing and it would be almost as tall as Celestia. It's actually a little thicker then her. So no. I was smaller then this. Actually, place that thing virtically on the ground." You do that. She looks at it for a moment before nodding. "Yeah, that thing is as long as I was tall." You clarify. "You mean when you're standing on 4 legs?" She nods. "Yeah. I was small but if I was standing on my hind legs, I would have been taller then this thing even back then."

You think. "Actually, why don't you just show me what you looked like with magic?" She nods and does just that. "Aw, you're adorable." She pets your head. "Please. If 1 of us is the adorable 1, its you." That hurts your pride but you don't mention it.

"Hey baby. If I'm not charismatic enough to build a harem, are you going to leave me because I don't want your cock inside me?" She hugs you from before. "Don't worry. I'd prefer a real woman but this toy should be enough for me to release the pressure in my balls. + even if you can't seduce Principle Celestia into hosting a prom at the school, we'll find another way for a bunch of people to recognize me as royalty. Or if thats not an option, we'll find another way to become powerful enough to concor both our worlds. We have our whole lives to figure this out, don't sweat it." Her words comfort you.

As you look at the projection you realize it looks alot like Cozmo. You speak to her in your head. "Hey Cozmo, are you originally from Equestria?" She asnswers you. "Yep. I remember I used to be an Earth Pony, but it was such a long time ago I don't remember anything from my old life. I can't even remember how I became a cosmic horror."

You feel sad for her. "Maybe after me and Sunset Shimmer concor our worlds, we can try to help you rember your past." You feel a mix of gratitude but tempered expectations sent to you. "I apreate the sentiment but that was countless years ago. Unless you can somehow go back in time, I don't think its possible for me to ever remember my old life." You smile. "Stranger things have happened."

You tell Sunset what Cozmo told you. She looks at you surprised. "Even if that was ancient history, I'm surprised I've never heard of a pony turing into a cosmic horror before. We know Cozmo at least has seen Celestia before since she saw an alicorn moving a star. So either Celestia and her have met before and Celestia has removed this knowledge from history for some reason, or Cozmo saw Celestia do this from a far and snuck away from her." You nod.

Sunset smiles at you. "Hey, can you take a shower? It was hot smelling me on you before but you're starting to smell bad." You nod and go do just that.
