Oh dear, seems the Decepticon scientist Knockout has invented some kind of shrink ray! Feeling particularly devious and playful, it seems he's shrunken the mighty Autobot leader, Optimus Prime, and put him to a better use... pleasuring that booty of his ;3
To this day I can't believe I've never drawn anything Knockout-related before. The 'con had a way of giving fanboys some real confusing feelings, if you know what I mean XD
