>"Honestly Tia, if you weren't going to continue the bloodline, who would?"
>Those words kept replaying in your head.
>It made you more angry than it should.
>Anon and you had ended your relationship months ago.
>But why was it he chose to go to your sister right away?
>And even worse, get her pregnant.
>A nagging voice in your head pesters you every night before bed-
>'It could have been yours. It could have been yours.'
>Was your clock ticking?
>Did you truly want a little one to raise?
>A little Prince?
>As you walk down the hall, you hear giggling.
>It sounds like Luna.
>But she never giggles...
>In one of the rooms, Luna lays on her back.
>She's giggling like a foal with a reddened face and holding her hooves in the air.
>Anon lays between her legs, rubbing his cheek on her swollen belly.
>"Anonymous, you're tickling us~!"
>He grabs one of her engorged teats and rolls it, "I just can't get enough. I almost want you to just stay pregnant."
>Luna wraps her back legs around his neck and thrusts forward, "Come now, you must keep stretching us so the birth comes easier..."
>He begins to undo his belt.
>"You know I don't need to do that. You're just horny."
>Luna draws her hooves to her chest and blushes, "Then take care of this. We- I can't spend all night backing my flanks against the wall again. I've been winking for hours..."
>You leave the sight quickly, feeling hot.
"Whywhywhywhy!?"
>Now you have to shower.
>And seriously think about the possibilities of a foal.
