Incubus Online: Buy One, Get One Free

"I ordered an incubus online, but when the package arrived, there were two of them. One was gentle and obedient, the other was hot-tempered and unpredictable.I immediately messaged customer service to ask if they'd sent the wrong one—I had only ordered the gentle kind.The reply came cheerfully. "Congratulations, you've unlocked the hidden variant! This model is a bit special—buy one, get one free!"Wait… what?I remembered hearing people say that raising an incubus is like raising a puppy, only better—they keep you warm at night and don't shed. Well, if that's true, whether I had one or two made no difference.So I ended up paying the price of one and getting two—what a steal!Or so I thought… until I went to feed them. That's when I realized I was the cookie in the middle of a sandwich. Apparently, "keeping me warm at night" was a strenuous activity."
