Laying down a straw man is a project management technique where you throw out an idea for review/criticism knowing the idea is probably flawed. Kind of like the 3 littlepigs straw house. Something made of straw is not likely to last.
While giving you a two-fisted handjob your girlfriend slides her top hand up your shaft while bending your cock almost horizontal and away from her to avoid getting splooged on.
"My old lady nearly tore my cock off trying to lay down a bunt last night."
