Liquid Centipede

Giving a centipede is sticking a swirly straw down a man’s penis, then pouring liquid poop down the straw. You the. Take the straw out, and let the shit into his penis. The man then pisses on his parters face, putting a mix of liquid shit and piss together.

I gave her a sweet liquid centipede last night!
