“I’ll have a cheeseburger with extra mayo.”
The customer is a smoking-hot anthro with a deep-blue coat. Her eyes are big and green and she’s wearing a black tank-top; size extra-small and paired in a mouth-watering combo with her extra-large cleavage.
The sun is out and heat rises in shimmering waves from the pavement. Just a few hundred meters away, the cool blue waves of the Celestial Sea lap at the white, sandy beach of Horse Shoe Bay; where hot young mares—some with four legs and others with two—play and bathe while on vacation for the Summer.
You look down from your lofty perch, stationed as you are in the window of the prestigious food-truck ‘Garden-Variety,’ where you and a certain four-legged pony called Honey Mustard work.
Your eyes are glued to the glistening beads of sweat atop the customer’s blue bosom, and it takes you a moment to register what she said.
“Of course, coming right up.” you say at last, blinking heavily to re-water your eyes. With Honey Mustard currently on her break, you step to the side and away from the window, manning the grill and flipping the patty yourself. In fact, it is Honey who typically takes the orders as she has some trouble with the spatula. It all goes pretty smoothly, until you realize you are out of mayonnaise.
You set the cooked patty on a bun and lay the cheese on top to melt, then find yourself thinking about all the mares out there in their shorts and bikinis, marveling at your good fortune.
Though yours isn’t the only food-truck around, you aren’t exactly short on customers. Apparently ponies, anthro or otherwise, tend to like a good veggie burger.
Or, at least, a veggie burger.
As you begin to wonder what you are going to do about the mayo, you notice your dick pressing up against the counter, which gives you a stupid idea.
Double-checking that you can’t be seen, you pull out your cock and start rubbing, thinking about that pony girl’s tits and how she is only a few meters away and yet she has no idea what you are doing and that you are about to—.
You discreetly cum on the patty, piling on a surprising amount in a few, staggering bursts.
You quickly place the bun on top, smooshing it onto the mixture of mustard, ketchup, ‘mayo’ and melted cheese, then deliver the order just as Honey Mustard comes in the back door.
“Have a great day!” you tell the customer, keeping an eye on her after she seats herself on a nearby bench. You watch as she takes a juicy, sensual bite, ketchup and cum dripping from the corners of her mouth and spattering onto her boobs. She wipes the excess from her lips and keeps on devouring your special sauce, totally unaware.
The whole thing makes you hard again, so much so that when you turn to face Honey as she steps up beside you she gets an unexpected poke.
“Woah.” she says, her yellow-brown eyes moving to the bridge between your crotch and her fluffy chest. At least you remembered to pull your shorts up.
Suddenly another customer steps up to the window. “Hi-ee-eye!” It was a glittery, glossy anthro with perky tits and a bubbly voice speaking up at you from behind a pair of giant sunglasses.
Honey looks over at her and then ducks back into the truck.
You turn to the customer, dragging your covered cock across her muzzle as you do. You can hear a subdued ‘Blech!’ from beside you, then you find yourself mesmerized by the ~~hot new pair of tits~~ by the sexy pony-girl looking up at you.
“Um, I’d like to have what she’s having.” She points to the blue mare on the bench, greedily sucking the last of your ‘signature fry-sauce’ from the fingers of her right hand while using a napkin to dab her tits with the other one.
You look back at the customer, then at Honey, then down at your pants. “That’ll be ready in just a minute.” You tell her, then usher Honey Mustard aside with your cock.
“Why are you hard right now?” asks Honey, frustration evident.
“Why are you hiding?” you retort.
“Because! Her little sister is friends with mine, and every time she brings her over to play that bitch casually insults me, or my decorating, even my snacks!
“Well, if that’s how you feel, you should know something about the burger she’s asking for.”
You fill Honey in on the details, and her expression changes from disapproval to disgust to sheer horror by the end.
“You mean that girl on the bench, she’s eating… That’s disgusting!”
“Exactly.”
Honey takes a moment to think.
“Honey, is that you? No wonder it’s taking so long. You should like, learn to whisper.”
She really is a bitch. You think to yourself.
“She’s always late to our sisters’ playdates, you know.” she says, addressing you now.
“But they’re always at my—“ Honey begins to say, then her face turns grave. “Do it.”
“Okay, but you’re gonna have to help me get hard again.” You say, pulling down your shorts and letting your cock flop out onto Honey’s snout.
“Wha- why can’t you just do what you did before?” she says, looking cross-eyed at your cock.
You press your cock against the cheek of Honey’s angry little face, and when she blinks her eyelashes tickle just a bit, making it throb and grow.
“Actually, I think I can manage from here.” you say.
Keeping back from the grill, you fry up another patty and with a few strokes have another special, this one made-to-order.
You let Honey deliver it, though she appears conflicted.
“Here you are, sorry for the wait.” says Honey, presenting the burger in a to-go bag.
“Finally. My little sister is gonna love this. Bye!”
Both you and Honey are speechless, frozen in place as the customer walks away with the sabotaged burger.
Author's Note
I worked on this sporadically and honestly don’t know how it will be received. 
It’s… weird. I guess the moral of the story is don’t mess with food because you never know where it’s going to end up. Or just don’t cum on it.
