Actual Wank in World of Warcraft
Tactic on the WoW Feathermoon server runs into two trysting Night Elves in the Deep Run Tram tunnel while they are deeply involved in manual transmissions. Since he IS on a Role-Playing server, Tactic gets into his role as voyeur and, uh, inserts himself into the action. I will quote nothing so as to avoid spoilers. Priceless exchange between Tactic and the neatly cock-blocked Night Elf.

Many pages of comments follow, including "Tactic, you are the man!" "stfu" "think of the children!" and an embarrassingly "omg we didn't know anyone would see us even though we were speaking in public emotes" post from one of the cyber-coitally interrupted, and the shared information from a mutual friend that the subterranean relationship could not survive the horror of the perverted dwarf.

Screen caps with sexually explicit and unbearably amusing chat text included.
