n., The Octopus is one of many sexual positions, similar in form to both the butterfly and "squashing the deckchair". The receiver lays on her back, with waist at the edge of a bed (ass hanging off). The giver stands next to the bed, with the receiver's legs on his shoulders. While penetrating, the giver may--at his discretion--lean forward to create extra tension. Increased tension causes increased tightness, resulting in a tight deep-dicking.
