>Be anon
>You agreed to babysit Celestia's filly sister Luna, not really sure why she chose you over someone who was more expereinced with babysitting, but she said something about you and Luna being "perfect together"
>Who knew you'd end up babysitting a god, for a god
>You already knew Luna beforehand, was always with Celestia, loved pranks, and would badger you to play videogames with her
>And every time she wanted to get back at you, she would devise some way to pee on you
>You remember when she stood on top of a doorway for more than five minutes, until you walked out, where she then dropped the entirety of her bladder's contents in less than ten seconds like a waterfall, or how you were chasing after he and she managed to pee in your face while running away
>It's insane her sister hasn't noticed your degeneracy when you try to get yourself in these situations
>You arrive to her room and see her with a controller in her magic and 13 empty bottles scattered on the floor
>"Nonny! Get over here! I got the game ready!"
>You sit your butt down beside her on the floor and start playing
>Fast forward, your trying your ass off to try and get Luna angry
>And it looks like it's working
>"Cheap shot!"
>You won the match with that shot
>Luna pushes into your chest and holds onto you, looking at you with a scrunched snoot
>"Lets switch to TV!"
>You're watching with her while she sits on your lap, you're trying to hide your boner with this filly butt almost directly on your cock
>Then you hear the hiss
>Holy fuck
>She's pissing on your lap
>Two minutes later and she's still going, your pants are completely soaked, and the floor underneath is covered in piss
>Pure ecstasy
>She pretends to look down and gasp, as she jumps off of you
>"You peed yourself!"
>You can't even speak properly
>You can see her still leaking a steady stream onto the floor, as she looks back and tries to close herself while winking
>"You totally did pee yourself!"
>You're covering your crotch to prevent your raging hard-on from being seen as you run to the bathroom change into new pants, and to jerk one out, it's not often you get to sit in filly piss as she pees on you
>You prepared beforehand by bringing multiple pairs of clothes
>You switched into a new pair of pants
>"Hey peepants, come on you're gonna miss the show!
>You come back and see ten more empty bottles on the floor and a slightly squirming filly
>You sit on the floor, with Luna following, sitting right back onto your lap
>The instant her rump touches your crotch she gets a cheeky grin and starts going again
>You slide your pants from under her and start hotdogging her
>She looks back and stares at you as you're between her folds
>Her warm pee continues for what seems like forever as you get closer
>You cum as she winks with her last spurt
>She just turns back and grins at you while you lay there
>"Looks like you peed yourself again"
>This fucking filly
