While in your hand the toy might seem unable to accomodate larger than average length or girth, all your concerns will be quieted as you slip your cock into this toy with a bit of lube. Although the vaginal length is listed as 5 inches, the TPE material has plenty of stretch to fit even larger than average cocks (this is based on personal experience, it's been a while since I've perused the section of the Kensey reports referring to size). The generously sized opening also greatly eases penetration. While users will not find the opening too big, or not tight enough, the slightly larger size does much to accomodate larger girth.
The shape of the toy allows for a great grip, which is especially important for a toy like this. The two ends are bulbous, with sort of a valley in between. This valley is a great place to grip the toy, as the two bulbous ends prevent your hand from slipping, even if you have a bit of lube on your fingers. This is a definite plus when compared to other masturbators with flat grips.
Once you've made your way inside, the beauty sleeve offers three distinct zones for your cock's enjoyment, each one providing unique and pleasurable sensations. The first zone, which runs the length of the first 'bulb,' consists of a tight passage with tightly packed rings which are extremely pleasurable especially during the initial insertion. The middle of the toy widens slightly with much larger rings, and these rings provide much of the pleasure as they massage your cock as you slide the sleeve up and down. What makes this toy truly explosive, however, is the third section. The final bulb widens to accomodate the head of your cock, and is filled with half-spheres, little nubbs which will send you over they edge as they work on the tip of your cock (with lube, try rotating the stroker, the nubs will drive you wild).
Realism was not important for me in selecting this toy, although I did appreciate the (somewhat) realistic vagina opening of this toy. The color certainly does not fit the toy, for ice queen this toy is not. (especially if you run warm water through the toy for a bit before its use). Since other sleeves I've tried have typically just had a round opening, the vagina does add a nice touch for users interested in realism.
One of the interesting distinctions of this sleeve is that the hole for insertion is the only opening on the toy. This allows for the buildup of suction as you use the toy, creating a very enjoyable experience. Some other comparable sleeves have a small hole on the 'head' section of the toy, presumably to allow for the escape of fluids and to aid cleaning by letting water run through the toy. I have found these holes much too small for insertion, and not too much help when cleaning the inside of the sleeve (although my partner does enjoy watching my cum shoot out of the top upon climax).
