This is like the middle option of the three fallen kingdom holes in terms of firmess and tightness. The spiral is very noticeable, and the texture at the end is a great head massage.
As good as it is, the Sister hole is more enjoyable imo.

The other reviewer wasn't kidding about only using this once, twice a week because this is INTENSE. No matter which angle you hold this at or how fast you stroke, your glans are getting a hard massage. This is so much tighter and harder than the other two onas in this series.

Given how hard and intense this is, you'll need a lot of lube. But it's worth it, because you'll be brought to toe-curling orgasm. The texture isn't that complicated, so it's very straightforward to clean.

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.
