A classic variant of "running a train" or an "eiffel tower". One participant bends over forward, as if having a traditional train run on him/her. Another does a back-bend over the original skeezer, so that their bodies are now perpendicular. Four other trash-barrel gutter sluts are involved, two being pleasured orally, two nailing from behind. These four are then being screwed from behind by four other participants. 10 people total must be involved so that the snowflake is completely symmetrical and multi-faceted, much like the sort that falls from the sky.
Some dirty Finnish tramp asked me to join her snowflake. Little did I know I'd be nonuple teamed!
