Olive Branching
When one man inserts his erect penis into the flaccid urethra of another man. The term come from a combination of images and word play based on the olive. The image of a pimento olive combined with the olive tree's branch as a symbol for peace (piss)... hence stuffing the head of a cock into her man's peace hole.
Tommy and Mike were caught olive branching. only one person was enjoying this.
