ceasar's wreath
A complex arrangement of multiple partners enggaged in anal sex; typically by homosexual formimg a simultaneous penetrative action and resembling a wreath as would be worn by a ceasar. At the base of this formation, two men share a long, double-headed dildo. Many multiple partners are then joined in simultaneous anal penetration with the partner in front of them. At the terminus of each series of partners, the unengaged participants give each other a handjob.
Seriously, I want to know what the world record is for the number of participants engaged in a Ceasar's Wreath!
