Sunburst: wow spike, i had no idea you were this strong, it's a shame will never know howstrong you really are in your normal size, since the book I used to shrink you got eatten by parasprites, which also had the spell to grow you back.

Starlight: Don't blame yourself too much Sunburst, we know you dind't mean for any of this to happen, you just wanted a living volunteer to test your experiments on, which Spike willingly agreed to help you with. Besides, while wait for Zecora to make a cure for Spike, there's 1 more experiment we haven't tried yet on Spike, one that i'm sure we can all take pleasure in together, if that's alright with you. I already know how much Spike is looking forward to this, since it was the only way I could convince him to agree to what i'm about to do next.

Sunburst: Well, as long as Spike has no problem riding my cock while we're having sex, I guess he can hang and stick around with us for a little while, until Zecora comes back with the cure she's making for him.

Starlight: hey there handsome

I hope you and that brave little soldier you snuck in your pants weren't planning on going back to Equestria just yet

cuz we still got 3 more hours left before that shrinking spell wears off on Spike

so what do say you we head over to Sunset's appartment and make the best out of those 3 hours, alright honeybun?

Sun: uh... sure... I mean, as long as Spike doesn't mind being tied under my dick while we play smash on my sister's couch, I guess we can fool around for a few more hours before we all head back to Twilight's castle.

as long as spike wants to hang we us, while we play smash on my sister's couch for a few hours, I guess we got plently of time too fool around, before it's time for us to head back to twilight's castle.

happily married Starlight while still being tiny.
