One of the men dons a mask, snorkel, and swim fins, and manually stimulates the other man's penis with both hands until it ejaculates underwater. He then dips the open end of his snorkel deep below the surface, and sucks up the clouds of liquid before they have time to dissolve, swallowing them whole.

The man's penis is submerged below the toilet seat level, with the rest of his body on the outside of the toilet.
