This is such a treat! The top soft opening is so plush and soft and pliable. The inside is also such a pillow soft, plush, pliable material that's almost like a bouncy house for your member, but silkier and softer. The inside does not start for an inch or 2 so either the smaller folks wouldn't work as well or take the container pieces apart to use that way. A variety of vibrations and turning! Really a sight to see, or actually a feeling to feel. I tried to get a decent picture of the interior and there's actually a tongue like part protruding from the bottom, which would be on the tip of you. And bumps along the way for more sensation. You will not believe the speeds at which this rotates! Really fascinating to watch and feel it do it's thing! Has a little weight to it, easy to charge. Expect to be impressed!
