"Alright. I'll help you. But let's have some fun first" Dirk grins.
"Are you demanding sexual favors for your assistance young man!?" you chide him. Dirk isn't as un-fuckable as you are right now (he is still a bit sweaty but at least he isn't covered in food and cum stains), however this brat needs to learn a thing or two about consent and coercion. "I hardly think that's appropriate."
"N-no, I... just wanted to play the MTH:RPG." Dirk immediately blushes and stammers "Marty is a bit... pushy sometimes so it's not always fun to play with him."
You immediately feel a little sorry for Dirk, and a bit embarrassed that you expect him to be as big a scumbag as Marty. You consider it for a moment before replying "Sorry Dirk, I really want to get back to my life as soon as possible."
"Umm the thing is we'd probably have to go back to the carnival to change you back, except there aren't any more buses running to the park anymore at this time." Dirk explains, "My parents took our car for the weekend and Marty is too lazy to get his driver's license so his parents won't let you borrow their car. I don't have enough money for a taxi and I think Marty is broke too because he spent all his money on anime."
You recall that wasn't entirely true. Marty spent all his money on an exclusive torrent site membership to pirate hentai. You groan in frustration and ask "So what can I do?"
"I could lend you some money for the bus tomorrow and we'll go back to the carnival together," Dirk suggests "But since you're stuck here at least until morning we might as well play..."
This MTH stuff isn't really your thing but since the guy was doing you a favor and you don't really have anything else to do. You might as well indulge him.
"Fine, what do I have to do?"
Dirks eyes lit up and he immediately starts rummaging through his binders and bags. "Well first you gotta make a character. Unless you wanna play Marty's character but I think he'd go mental when he comes back."
You look down at Marty Nighthoof's character sheet. The stats and items mean very little to you but you saw under the notes and background details Marty had listed "Irresistible Stallion" as a feature and "Too intelligent for his own good" as a flaw. Under the sections for height and weight you could see a section for Penis Size which looks like a different font to the rest of the document almost as though it was added after the fact. Here he had scribbled "Huge (4ft)".
Dirk hands you a fresh character sheet (You notice there is no section for Penis Size on this one) and starts reading off the types of Horses as well as Classes.
