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 an anus. 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
