Funny you should ask, I just modded it again.
The boost is my go-to, but despite my best efforts I found my sessions being much shorter. So I decided to remove the rings @Endlessdream
It definitely cut down the intensity, however just a little too much. Even with the rings removed I’ll still continue to use the boost on the regular. After all the mods what I’m left with is an original recipe Fleshlight sleeve, with quite realistic feeling lips and a very very nice suction action. The only thing missing is a extended tongue with a proper human tongue texture. I might end up ordering another one, but for now I’m waiting to see what the guys at Fleshlight are cooking up. If they release a version of the Turbo made out of the boost material, I’ll definitely be ordering one.
