Master Series 響尾蛇充氣肛塞

Didn't expect the pump feature to make such a difference, but being able to adjust the thickness mid-use is a game changer. The beads give a nice steady sensation on the way in, and the inflatable part takes it up a notch when you're ready.

The jiggly inner balls are what sold me — that subtle rattling sensation with every move is way more fun than a plain plug. Being able to pump up the thickness mid-session is a game changer, though go slow with the inflation or it gets intense fast.

Wasn't sure about the beads at first but the pump really lets you dial in the thickness, which I didn't expect to use as much as I do. The jiggly inner balls add a little rumble that's honestly the best part.
