Sex Position: When in the missionary position, the gentleman sits back on his knees, grabs the two legs of the lady, and brings them vertically together, as if she looks to be in a 'L' position. Then, he pushes the legs back, to where her knees are about touching her chest. At this point, the green light is on, and the trash compactor is initiated.
