In the back yard, behind a white house with a large two-pane window, next to a broad white wooden staircase like a ladder over a bed of green ferns, mailman Carlos Cruz (brown, black candado mustache and goatee, tattoo on upper right arm, nipple rings, green and red tattoo on left hip) squats and sucks Sweet Williams (pale, clean-shaven, right black wristband); Sweet sucks Carlos; Carlos rims, sucks, and then tops Sweet from behind as Sweet bends over the stairs.
