Adelaidean Tugboat

Sexual manoeuvre where both the male and female participants are bent over holding there own ankles, with both partys butts up against each other and at the same time the males penis bent back into the females vagina (Think of how dogs have proper sex, butt to butt), at this point both the male and female start shuffling forward at the same time whilst making the noise of a tugboat - bub bub bub bub bub bub TOOT TOOT

Hey hunni, wanna go down the Torrens on the Adelaidean Tugboat?
