Satisfyer Spectacular Duo - ライトグリーン コック＆ボールリング

Wasn't sure about the double ring setup at first, but having one loop around the shaft and one around the balls keeps everything snug without pinching. The vibration carries through both rings way better than I expected.

Wasn't sure a vibrating ring would do much, but the second ring around the balls makes a real difference. The vibration carries through both instead of just the shaft, and it's stayed snug without pinching.

The dual-ring design genuinely surprised me — the testicle ring adds a whole different kind of stimulation I didn't expect from a toy like this. The vibration is strong on the higher settings and it held its charge through a long session without fading.
