Epi guzzling

The act of sticking a long tube into the male penis, through the urethra and into the epididymis tubes and sucking out the seminal fluids with your mouth. This technique is used both to pleasure a man, and to extract fresh sperm to be genetically modified for the creation of Urethrals.

Dan: Bro I didn’t know your girl knew how to epi guzzle! She was epi guzzling me so fucking hard last night!

Bob: Wait why the fuck were you with my girl?
