手榴彈湧浪

The spiral interior texture is what sold me—the combination of that with the auto-suction feels way more intense than I expected. Cleanup is quick too since the sleeve comes right off, which honestly makes me reach for it more often.

I was a little skeptical about the auto-suction feature, but the pulsating contraction technology really does work—it feels surprisingly natural. The interior texture adds a nice layered sensation that keeps things interesting, and cleaning is quick with the removable part.
