We have the same sleeve and found it fits nicely onto the end of her smaller vibrator and more importantly onto the end of our fucking machine - have yet to use it in anger but - pics hopefully to follow - here is one of wide trying the sleeve for size 😀We started with an 8” suction cup… then he got a sleeve that adds 3” to the end and makes it thick as hell… then we decided to go crazy and put the sleeve on the suction cup… good times, good times…
