SEI MIO - サイレント・オーソリティ - プログレッシブ交換可能ボールギャグセット

The straps adjust way easier than I expected, so we could switch positions without fumbling with buckles. Having three sizes to work up through made the whole thing feel less intimidating for a first-timer like me.

The three different ball sizes let us actually work up gradually instead of guessing, and the silicone feels smooth with no weird smell out of the box. Swapping them mid-scene takes two seconds, which matters more than I expected.

Swapping between the three balls takes seconds, which is nice when you want to change intensity mid-scene without breaking the mood. Only gripe is the storage pouch feels a bit flimsy for the price.
