I was really fighting with myself to write a review about it, because I was unsure what to think of it.
First of all, this onahole is harder than you might think. The entrance of the tunnel is designed like a twisting tunnel, but the material is so hard, that you wont get that kind of sensation out of it. Then the tunnel does a curve downward, which leads occasionally to pumping into the curve wall.
So the idea behind it is very good but it just doesn't work out for me...I had to fight with this thing and force myself intro it...even with lots of lube.
Thats the bad thing I have to say. The good thing is, that it is built very well. It is heavy, thicc and durable. So because of the thickness, you don't feel your own hand...which is very nice of course. And it makes the impression that it is very robust and will last a long time if you will.
So in summary:
The stimulation is a little bit to much for me I guess...it feels just hard and I can not really get pleasure out of it...but maybe thats just me.
But if you like a very tight and hard tunnel, you might get this thing to work for you.
