How about it starts with me sitting on a toilet. I start shitting so much that it starts seeping out of the sides of the seat. Then I throw up like a gallon of mostly dry tuna, so I have to hack it up really hard and painfully. After that, I take my hand, twisted into a claw from being stuck in a drain and removed roughly, and just start beating off with it, moaning as tuna pours from my mouth and nose. My eyes are watering from the puking and smell, so as I climax, the only holes in my body not expelling a liquid are my ears.
