This sleeve for the Autoblow Ultra was specially constructed for use with the Autoblow Ultra Vacuum Cap, the Ultra's stroker case, AND your VacuGlide milking machine.
If you already own an Autoblow AI Ultra, in order to enjoy this sleeve, you only need to additionally purchase the Ultra stroker's vacuum cap.
If you do not own an Autoblow AI Ultra, you should add Ultra's stroker case plus the Ultra's vacuum cap into your order.
The sleeve is closed at the bottom which causes VacuGlide's suction to work even more effectively within the Ultra's stroker case. The sleeve has an extra cusioned top portion designed to minimize air leakage for the tightest possible vacuum-induced stroking experience. Although you can use this sleeve inside of your Autoblow AI Ultra machine while operational, due to the sleeve's design being optimized for VacuGlide suction stroking, you may find it easier to use this sleeve as a standalone tool with the Ultra's stroker case only.
Note that the extra tight version has a very narrow channel for penis insertion which requires a lot of lubricant and the ability to have a strong erection to penetrate it. Watch the video below to learn more and remember you must insert your penis FIRST prior to turning on VacuGlide!
