The Autoblow Ultra is compatible with a series of interchangeable sleeves displaying different orifices and having different textures. Made from realistic feeling TPR, this beige-coloured anus sleeve has an extra small internal diameter with a smooth internal surface for the most realistic simulation of the inside of a mouth. The Ultra sleeves are the easiest to clean because you can run soapy water through the top of the sleeve through a hole at the bottom, and easily dry it.AI Ultra masturbator is sold separately
