Enema

I enjoy standing in the bathtub/shower as I jack off. I have an enema bottle in my ass and just as I cum I squeeze the bottle and fill up with the fluid. I then try to hold it in as long as I can. When I get to the point that my stomach is in knots, beads of sweat roll down my face, and my asshole can't hold it in anymore, I make my way to the toilet and release. It gives me a sweet natural rush. I often end up jerking one more time as I sit on the toilet, covering my belly with sticky goop. It's a great way to clear the pipes on both ends.
