Double layer masturbator.
With no change in texture, it gets pretty boring after a while. Feels very grippy on the inside but in a "not great not terrible" kind way. Also some of the sides feel quite thin because of the internal shape. There are better alternatives in this price range.
I bought this onahole while it was on sale along with a fairy doll. I am glad I did buy this onahole for the doll because it fits perfectly in the fairy doll which has a smaller then expected onahole insert pocket. This hole feels good and it quite durable for its price range. The hole is soft but tight and the ribbing gives a good sensation. It no where near as good as a meiki or the zxy but does a good job for the price, and is perfect for a fairy doll insert. my only grip for this hole is the entrance is hard to get into and lube due to it being just a slit on a dome and due to how tight the hole is, which I had to spread open to get into.
tl:dr - good insert for the price, fits perfectly with a fairy doll, but a bit hard to get into and lube due to the design of the entrance.
