The Crystal Mouth has only one use, to simulate sucking your cock. It's not very large 3 1/2" long, so don't expect deep throating, but it should fit almost any size cock. Like most all masturbaters the Crystal Mouth is hand held and manipulated.

The Crystal Mouth is made of TPR which makes it extremely soft and squishy, something necessary for all masturbaters. Tpr has no smell. The Crystal Mouth is swirl textured inside but because it's so soft you really don't feel much texturing.

The Crystal Mouth has lips and a nose which actually look fairly life like even though they're rather small. When I first saw it I could have sworn it would never fit over my cock, It's very small, 3 1/2" long and 2" wide. I was wrong. The TPR is very stretchy and slipped over my 2" thick cock very easily. I don't think anyone of any size would have trouble using the Crystal Mouth.

The Crystal Mouth preforms it's singular function, stimulating a cock very well. It felt very nice slipping and sliding up and down on my cock. Being only 3 1/2" long I had a tendency to pop out the other end but found it still very stimulating. I have used it in the shower and loved the squisy wet feeling while I stroked.

The TPR that the Crystal Mouth is made of is slightly porous and can't be boiled or cleaned in a dish washer. Use soap and hot water only to clean it. It turns inside out easily to clean and dry the inside. The outside feels slightly sticky so I store mine in a plastic bag. TPR is compatible with both silicone and water based lubes. Being slightly porous I reccomend not sharing The Crystal Mouth because it dose'nt work well while wearing a condom.

Packaging was disappointing. Mine arrived in a cellophane bag stuffed in a soft mailer, no cleaning instructions of any kind. If you weren't aware of how to handle TPR it could cause problems.

I have to admit I prejudged the Crystal Mouth when I first got it because of it's size being rather small. I thought I'd never get my 8 1/2" by 2" cock stuffed in that little mouth. Well luckily I was wrong and after washing the Mouth and squirting a little lube in it the Mouth slipped over my hard cock nicely. At first it only covered my swollen cock head but that really felt great. I started stroking and before long my cock head was popping out the other end so I just worked it on my cock head holding my finger over the hole in the other end. This created a nice sucking feeling on my head and stimulated my cock a lot. The Crystal Mouth is clear with a pink insides and made my big cock head look huge inside it. I really didn't notice the textured swirls inside the Mouth, but it still felt great. I pumped it full of cum in no time, so it worked as advertised. I gave it a go in the shower and had the same wonderful results. The Crystal Mouth seems to be thicker than other masturbaters that I've used so hopefully it will last longer for me to enjoy.
