Dorcel ウェイビープラグ

The wavy texture feels surprisingly smooth going in, and the varying ridges give a unique sensation with every twist.

The wavy ridges hit spots I didn't even know I had, and the curve makes insertion way easier than my old plain plug. Washed it off in seconds and it's ready to go again.

Wasn't sure the wavy shape would make much difference but the texture gives a totally different sensation than my old smooth plug. The curve means it stays put without me having to hold it, which is a first for me.
