"Oh my god!" Stiles was up off of the bed the moment the black liquid hit him. He had to hold back his own gag reflex as he tried not to think of what was on his chest and seeping into his pants.
"Thanks, Derek, and here I had you all cleaned up," Stiles said moving to open a window to get the smell out before looking back to the bed. The black stuff was everywhere but mostly on Derek. He needed a bath.
Sighing softly Stiles moved back towards Derek. "Just... don't move. I'm going to go start the shower. You need one."
