1.I won't use motor oil as base anymore;2. Yes, quite a lot paint is still in the bladder. 3. I'm so sorry about that, and I realize that now. I'll only dispose of water-based paint down the drain. 4. Thank you!
Four things: 1) petroleum is acutely poisonous on your skin, let alone inside you; 2) ejaculation does not empty your bladder, where this seems to be going to and returning from; 3) putting motor oil and paint down your sink drain is bad for your plumbing; and 4) this is hot as hell!
It feels strange, but for me, there is a strong sense of pleasure. Watching my dick, urethra and bladder turn silver is quite fascinating. The liquid, or silver paint, is denser than water and does not dissolve in it, so it layers and settles beneath the urine.
