With a wider hole and a consistent pattern of nubs that'll caress your shaft, this can keep you on the edge for a while. It's the right amount of sensation without putting your dick in a vice grip!
Also, it's not greedy with lube like other toys :)

Off the bat this is a lot like Heavens Ex-Hard but if it were softer and cushier. It begins with a light teasing on your entire length but then becomes a consistent pleasure once you're hard. Around the midsection there's small spaces that allows the texture to catch on and tease your glans. The cushioning around the opening makes for interesting "plap"s once you speed up.

If you're less sensitive, the combination of softer material and stimulating texture makes for a fun edging session.

The opening is a little smaller so it gets tricky to clean every inch of this hole.

This lube is so thick it's hard to even get a decent amount out of the bottle. And when you do, there's not a lot of moisture so it quickly becomes dry and tacky. If you're picking this though, water it down or have water spray handy.
IMO, get Onatsuyu.

Ride Japan really did it with this one. The opening is a little small for me but that's great for suction, and the hard texture is really stimulating. It's comparable to Carnivorous Mermaid but if it were softer and easier to move around in, and only slightly less intense. The hard material really likes to cling onto lube so this is harder to clean.
It's really nice that the opening also has some cushioning so you can go all out if you like.

The texture is as good as it looks, but you need thinner lube to feel it through all the softness. It reminds me of Orochi but if it were softer. The tight opening is great for suction.
