In an Alabama three way, three men get each other close to cumming via anal sex. They then all pull out, and arrange themselves in a penis to head circular'ish configuration, laying down. Finally, each smacks his own cock against the forehead of another until he cums, spewing semen plus a frothy mix of leftover anal lube and fecal matter all over the top of the smackees' faces.
During a televised roundtable, the announcer noticed the each member of the discussion panel, Rick Saintwhoreman, Mittens and Salamander each had a small mushroom shaped bruise on his head. When she asked what they were from, they said the bruises were from their previous night's vigorous Alabama Three Way congress.
