Nexus - B-Stroker - バイブレーティング・バットプラグ

I was skeptical about the stroker beads at first, but the way they dance up and down inside is genuinely unique—works just as well vaginally as it does anally. It's quiet enough for solo play without worrying about the whole house hearing it, and the sensations keep building until you're done.

The little stroker beads inside really do their own thing, which is a fun surprise during use. It works as promised both ways, though I wish the vibrations were a touch stronger for my taste—still, a solid pick for the price.
