An acrobatic position change performed during doggy style
sex. The male starts to curl the girl's legs against her chest, then grabs her thighs and forces a sudden rotational movement along her anteroposterior axis. This will normally make the girl land on her back (180 degrees). Can be pushed to the limit by trying a 360 degrees rotation.
Last night I was doggying my baby, when all of a sudden I tried to perform a Versa Switch. I applied too much force, so she just slammed her head against the wall.
