I recently started watching Supernatural, and there was an episode about shapeshifters (S1 Ep6, I think) where the shifter themself was sentient and would literally "download" the information about the person they were shifting into. For some reason, all I could think about was Xavier from Love and Deepspace and MC encountering a Wanderer with the same abilites.
Sentient wanderers were rare but deadly, and rookie hunters would die trying to even find it, so you and Xavier were dispatched to hunt it and kill it.
At 12:00 AM, the wanderer broke into the Linkon Hunter HQ office in Xavier's skin. It had taken a particular interest in Xavier; a man from nowhere; no secrets, no weakness. Nothing. If the wanderer could get enough information about Xavier, it could easily replace him and eradicate the Hunters Association from the inside out. It had studied Xavier closely from the shadows; his eating habits, sleeping habits, and mannerisms, and was able to copy them down to a T. Every night, the wanderer would break into the office and appear as someone new, but would wander over to the same spot: Xaivier's desk.
You and Xavier tracked its moves to the sewer system in front of the building and waited for it to appear. When the Wanderer approached Xavier's desk to look through his belonging and files, you appeared.
Xavier watched from the shadows.
"Didn't expect to see you here so late at night. Shouldn't you be sleeping?" You inquired as you made your way through the maze of desks. Your eyes were locked on the target.
"I could say the same for you," the wanderer smiled and put his hand on his hip. "You always complain when we have to do late-night calls."
"You know," You started as you waltzed over the wanderer, "I was hoping to catch you here," You stopped directly in front of the wanderer and stared into its eyes. Your target was right in front of you.
"Yeah," you whispered. You grab the wanderer by its harness and bring it closer. Your chests were touching. "I always hope to see you." Just as your lips grazed the wanderers, a loud gunshot rang throughout the empty office.
The wanderer stumbled back and emitted a shrill shriek; it's body melted into a cracked and leathery limb that you couldn't even decipher. As it raised its deformed arm to attack you, Xavier's blade swiftly cut off its raised limb.
It was 2:30 am by the time you and Xaiver defeated the wanderer. You watched in mild disgust, and Xavier in apathy, as the wanderer melted into a puddle of guts and blood before disintegrating entirely.
Xavier's neck felt hot as he remembered how you pulled the wanderer closer to your body; his breathing turned shallow as he remembered how you eyed the wanderer as if you were a predator, and it was your prey. His body felt warm. In that moment, he wanted to be the wanderer, just to feel your hands bring him closer, and your lips graze his.
"Welp, partner," Your voice sliced through his fantasies like a blade. You turn to him and smile lazily. "Do you want to do the report, or should I?"
Xavier smiled at you. "You're better at writing reports than I am."
Xavier chuckled as you pouted and attempted to bargain with him.
After bidding you goodnight and closing the door to his apartment, Xavier leaned his back against the door, placed his head in his hands, and sighed. He couldn't help but think of you in that moment. Beautiful, eager, predatory. His ears rang and his cock throbbed thinking about it. He hoped that one day, you would look at him like that.
