This realistic onahole is based on Japanese Adult Model Sakura Miyuki.
At first sight you take it out of the box, it is rather smaller hole. Has rather shallow tunnel of about 13 cm, so not best for long Johns. Outside looks and feels more harder and rubbery to touch. Internal layer also feels harder and more as rubber. Feels ok and not uncomfortable due to mild texture, but is not really soft or realistic due to harder material. It is nothing like double layered holes from NPG, but looks to be more durable due to this. Hole also has very tight and small enter point, that you would have hard time to get into even with normal circumference, but would give you an good snug hold on your shaft. Can say nothing really special here. Perhaps more experimentation with different lubricants. It also comes with 50 ml bottle of lubricant, which is completely useless as it is like thicker and very sweet water. It is without any sliding or slippery properties. Not sure why they even added it.
