矽膠肛門珠肛門塞柔軟肛門訓練器肛門鏈5球

The five balls give a nice gradual stretch that's perfect for building up. It's flexible enough to curve with your body, and the smooth silicone makes insertion feel comfortable right away. Cleanup is easy too, which is a big plus for me.

The silicone is very smooth and soft, which made insertion much easier than I expected. It stays in place well during use, though I wish the balls were slightly larger for more sensation.
