There is or was an attachment called the "Vortex" which fits on the hose of a cleaner. It has a collar which you rotate to adjust the intensity. It basically wobbles the clitoris about fairly strongly. You can actually make a homemade version of this device fairly easily but it's difficult to explain on an xhamster post. There is a short video somewhere on xhamster of a woman using a Vortex. She is wearing crotchless knickers which makes it much more fun to watch.
What a gorgeous subject skillfully taken to the edge and beyond. This was just so arousing to watch and see her juicy vagina and urethra releasing their endless supply of secretions.
