This is based on an art prompt over at the newly created kink art prompt community
spn_kink_art. The prompt was: Cas is performing sweet, sweet fellatio on one of the Winchesters, while the other is banging him from behind. Both Winchesters are high-fiving above Cas, thus forming what looks like the Eiffel Tower.
Warning: NSFW, and explicit nudity. (yes, contains visible peen).
