A modified version of the Doggy Style which can only be achieved with long haired women. In this sexual practice, the woman has some sort of String or anything that can chocke her in her mouth. The man pulls the String behind and forces her to face upside.
What you hope for are strokes, strong enough to give her a push forward while she is still able to hold onto the string, accompanied by deap sexual roars and her hair covering her back like a bears pelt.
Yesterday I tried the Moscow Bear Slinger and it went well until she bit through the cloth.
