Be sure to squeeze out the excess air before sliding in. This will unlock top tier suction. The tongue at the end is fun to play with, not just a gimmick in my opinion.
The only flaw with this one is the area around the lips is incredibly thin, this will end up tearing with normal use. Once that happens you lose all suction. Easily 5 stars if not for this issue.

Life like size and weight. You're gonna need to be fairly strong if you want to lift her up and down for more than a few minutes. That being said, you can also set her down and have fun pumping your hips in and out of her. She is made out of super soft materials that just melt on your member. Spank her and feel the vibrations while inside her. You definitely need a hip in your inventory and this was it for me.
This review was written after a few years of owning her. She is staring to tear towards the flat end. Even with careful maintenance the TPE is falling apart. Maybe this is inevitable with the soft material.

Super fun to try all sorts of positions with her. You can grind with her in a way that you can't with regular onaholes. Set her down on a table and go to town. Or go with the classic cowgirl(my favorite). The breasts are fairly big, but are too stiff to go for a good paizuri. The two holes are connected and that's supposed to help with cleaning. I don't like this because you lose out on suction, but you can seal up one of the cavities and that will solve the issue. The inner skeleton does work, she won't flop around. The inside is a 5/10 on the hardness scale. She is also very deep for us longboys ;).
This is a review after a few years of owning her, and she is still holding up strong. No apparent signs of wear and tear. You will pay a high price for ViViDoll Ayaka, but rest assured that this is a QUALITY product that will last you for years with proper maintenance.

The natural evolutionary peak of oral toys. The dual chambers inside will create an intense vacuum. Hold her head and rock her back and forth thanks to the inner skeleton. Push her back and watch her gobble you up and her way back. She might be too big and unwieldy for some, I think she really is meant to be set down for your session.

The Venus Real line of onaholes are meant to be starter holes in my opinion. If you already own plenty of toys than don't bother. But if you're just starting and are looking here, then do yourself a favor and get the Venus Real Soft instead. If you are experienced and are looking for something hard, then there are better options out there in my opinion.
