Wikus knew this was wrong. It even felt wrong. Weird appendages clambering around, oddly smooth skin pressed against his. The complexion was all wrong. Green-ish. Mixed with something else? He can't place it at the moment and, more importantly, doesn't want to. He thrusted inside the odd creature and felt a little sick with himself, but raw desire threatened to peek it's head out and he got lost in sensation.
The prawn, Christopher, made odd clicking noises and shifted underneath Wikus. The prawn was speaking in his native tongue and Wikus could only catch random words of encouragement.
"More, hard, fast." He heard him say in soft pitchy noises.
Wikus stopped all of a sudden. He kept his eyes closed the whole time, too ashamed to meet Christopher's eyes. He was still hard inside of the Prawn. Christopher appendage came up and touched Wikus on the cheek. A faint whisper in strangled English made his eyes snap open.
"Pl...ease," Christopher said. "Please."
