"What about this new costume shop they opened a couple of weeks ago?" She proposed.
"That's a good one, we barely have any costumes, just the same old witch and mage costumes we bought years ago" you laughed with her.
You two walked to the store, looking like a regular costume shop with the occasional crappy Halloween decorations, however you felt a strange aura as you entered the shop even if it looked the same.
The bell touching the door rang and, looking an old lady at the bottom of the shop. "Welcome dear costumers! You'll find all that accommodates to your desires! Buy one and get the second for free" she said. "And there's no return... So pick your option correctly" she smiled.
"Babe, I have a bad feeling about this..." You whispered your girlfriend.
"Come on! They look really good, besides they are really cheap and can get our two costumes for the price of one" she said looking at the variety of suits, werewolfs, vampires, a horse suit for two persons, android, anthropomorphic animals, and the list continued as you kept walking the shop felt like it was infinite.
"Ok hun" she convinced you, "But which ones are we going to pick?"
"I know perfectly what I'm going to be!" She grabbed her suit.
