This sexual endeavor involves a standing male and female who are both unclothed at the top of a cobbled hill covered in lube. Man runs towards female backwards and back flips so his erect peni ends up in her mouth. The force of the flip then slams the womens head to the floor causing concussion and thus both members of the act slide down the hill in a 69 position.
