Take any other disposable onahole. Even the Tako Musume is better. Here you can read why.
By the way yes it’s too tight for westies, and the too small hole doesn’t allow the air to flow in/out quick enough which greatly ruins stroking pleasure and is noisy.
Pure should be like this inside, very similar to a Tenga deepthroat.
I don’t know if KM Produce makes good porn, but for onaholes that’s nothing to be shipped overseas.
