Octopus

A variant of the Butterfly. The woman lies on her back and lifts her legs straight up in the air. The man kneels (or stands if done at the edge of a shorter bed) and lifts her pelvis high enough to fuck her.

Playing the Cello

A modification of the Octopus. The woman lies on her back with her legs together, pointing straight up. The man kneels and puts her legs on one shoulder or the other (over the left shoulder is the proper “Cello position”) and tries to fuck some nice tunes out of her.
