To preform a Diocletian is the high water mark of a EPIC sexual life.
The move requires four separate girls (one from Turkey, one from
Serbia, one from Italy and one from Germany) and three other bros. First you make it appear like you are going to have all 4 girls to yourself. Then you invite the other bros in, each to take one. All present
climaxing at the same moment.
The ultimate expression of power and bro.
