ハニ ペニスエクステンダー 18cm

The waterproof material is what sold me, cleanup afterward is way easier than I expected. Thickness boost is noticeable too, my partner commented on it without me saying anything.

The material is stretchy enough to roll on without pinching, and I actually noticed the extra thickness right away. It stays put during use and the waterproof finish makes cleanup way easier than I expected.

Wasn't sure about the extra 5 cm claim but it actually delivers, and the added thickness is definitely noticeable. The elastic material stretches way more than I expected and doesn't slip, which was my main worry. Waterproof too, so cleanup is easy.
