That could be fun. Tie the girl to the shower head and run the cold tap. Turn it off and let her shiver while nailing her to the wall with my dick. Her arse wet enough to get into but with water, not cuntjuice or lube, making it a dry, painful fuck. "When I call you a dirty little bitch, it's because you're a dirty little bitch. I could leave you under this shower for a fucking week and what would you still be, cunt?"
