You've booked a night at an exclusive whorehouse, catering to the fantastic. Bewildered by the choices available, you simply ask the Madame for a "Unique experience". You are escorted up to a luxurious room, where you are directed to take off your clothes and wait on the bed for your girl to arrive when she does you are shocked to see it's a tiny fairy. She flies over to you and lands on your hip, right next to your cock.
"Hello, my name is Ismelida. I'll be your single-use whore tonight." she says, her voice so high as to be barely intelligible.
"Uhh, ok. My name's Anon."
You look at the tiny fairy standing next to your cock. It's almost as big as she is. Ismelida is about the size of your hand, at most nine inches tall. Her skin is fair, her features tiny but exquisitely formed. She has a petite little nose, rosy red cheeks and large, blue eyes. You couldn't possibly fuck her without destroying her.
"I think there's been a mistake." You say, "You see, I was here for a prostitute."
"Oh yes sir, that's me!" she smiles and nods.
You're speechless for a moment, before stuttering "But... you're so small. There's no way I can fit inside you"
You expect an excuse of some kind, but instead she giggles and smiles. "That's why I'm single use!"
"Single... use?" you ask.
"Well, to fuck me just need to grab me in one hand like a beer can, and impale me on your cock! As long as you do it hard enough your dick will punch through my pussy and into my torso. Then you just masturbate like you normally would, except my body will be wrapped around your dick."
"Is this some kind of sick way to say I can't fuck you?"
"Oh no sire, that's not what I mean at all!" she squeaks concernedly. "You have to! If you don't fuck me my sisters won't be paid."
"You just said you'll die."
"Don't worry about that. Just throw my body in the trash can beside the bed." she starts to take off her tiny dress. "Should I start with some foreplay? Your dick won't fit in my mouth, but I can lick the tip."
