Nexus Simul8 Wave 雙重前列腺按摩器（附雙陰莖環）

The wave motion on this is way more intense than I expected, and the two rings actually stay put instead of sliding around. Took a couple tries to figure out the angle, but once I did it was worth it.

The dual cock ring keeps everything snug while the prostate arm does its thing, and honestly the wave motion is what sets this apart from anything I've tried. Wore it for about half an hour the first time and had zero discomfort.

Didn't expect the wave motion to be this noticeable, but it hits a rhythm that builds slowly rather than rushing things. The dual massager plus the double ring kept me in the moment way longer than I planned. Worth every penny.
