A group of fully aroused men perform a manual sex act whilst surrounding a consenting filthy grubby dutty dutty biatch, and in turn explode thier load (ejaculate) onto the afore mention dutty dutty slut, onto whatever part of her is adjacent to them. When each man and his little feller have fully deposited in turn, and only then have you acheived a MEXICAN WANK.
Craig: We found this dutty bird last night so me and the rest of the team did a mexican wank all over her.
Rob: Wow! Did she enjoy it?
Craig: No! there were loads of us she nearly drowned.
