Flexiblity is sexy! Give her a chance to show it off with the ballerina sex position. This is another one of those difficult positions made slightly easier with a swing... not easy, "slightly easier". This will most likely require a dual hook swing because the straps need to be installed 6 to 8 feet high for her to get her legs up that high and a single hook bar will just cause it to drop too low. This position will probably also not work with a stand, but who knows, get creative or stick with the short girls.
