When 2 lesbians play tug of war with anal beads for pleasure, than the loser of the match will be fingered really hard till they squirt.
I just lost a match of Dirty Henrickson.
When two lesbians play tug of war with their vagina using anal beads as a rope and the loser gets tied up to a wall and furiously fingered till they start to squirt from their pussies.
"Me and my girlfriend played a round of dirty henrickson. I won!"
