特別雙肛塞

The silicone is genuinely soft, which made insertion way easier than I expected. The metal ball rolling inside gives this subtle continuous motion that keeps building the longer you wear it. Ended up keeping it in much longer than planned.

Didn't expect the inner metal ball to make such a difference, but every time you move it shifts and the sensation builds on its own. The soft silicone keeps it comfortable for longer wear too. Genuinely surprised how good this feels.

The two metal balls rolling inside are what really sets this apart — the movement builds gradually instead of hitting you all at once. The silicone is genuinely soft, so it's comfortable even for longer sessions.
