Guaina Fallica 流暢陰莖延長器

I was skeptical about the 7 cm claim at first, but the stretch really does add noticeable length once it's on. It fits snugly to the shape and didn't slip at all during use, which was my main worry with a sheath.

The lattice material feels surprisingly soft once it's on, and it hugs the shape without slipping. The extra 7 cm made way more difference than I expected during use.

Wasn't sure how the extra length would feel, but it stays put and adds a good few centimeters without slipping. The latex stretches to fit snugly and cleanup afterward is quick.
