The quality of the construction is of a high standard, and there are no scratches or chips in the surface, nor any bubbles within the glass itself. Borosilicate glass is actually a very durable material, so it should be able to withstand a reasonable amount of abuse without becoming damaged, and there’s absolutely no need to worry about it breaking during use.
Glass is a wonderful material for those who enjoy firmer and more rigid toys, as just by the very nature of it it can apply pressure substantially to wherever you want it. Glass is also a great material for temperature play as it holds both heat and coldness well, whether you want to warm it up in a basin of hot water, or cool it down in the freezer. The only material which really beats it for this is metal.
When it comes to using the Mister Twister it’s a very easy toy to insert. At the rounded tip it starts off with a very modest circumference of only 3″, and this gently tapers out to the widest point of 4 5/8″ at the opposite end. With only a moderate amount of lubricant the tip will slip comfortably though even the tightest sphincter, feeling like nothing more than a slightly thick finger, and the smooth surface of the glass in this area aids the process. As you continue to steadily insert the plug the shape of it expands the sphincter at quite a slow rate, so if you’re not too familiar with anal play it’ll definitely ease you into the process, and not come as a sudden shock to the system. The spiral texture of the plug starts to become apparent the further you get down the shaft, and is quite a welcome addition. The texture is quite subtle, with the ridges being rather narrow, shallow, and packed closely together, so they provide a pleasant stimulation to the anus without being too intense. Their inclusion definitely adds an extra dimension to the plug and makes it a little more interesting; it’s enough that it shouldn’t scare off a beginner, but will still be satisfying to a more seasoned anal-player and lover of texture.
If you’re thinking of wearing it as a plug then there are a couple of things to note. The first is that it is a little on the long side. By the time my sphincter was just about resting on the neck of the plug I could feel the tip of it pushing firmly up against the top of my rectum, and it was borderline uncomfortable. After a while I became accustomed to it, but being 3/4″ shorter would have been more ideal. Obviously this depends on how well you know your own anatomy, as it may prove less problematic for some and more for others; just be sure to insert it slowly as you approach the neck, as once the sphincter slips over the widest point the remainder of the bulb does tend to get sucked into the body, and if the plug is a little on the long side for you then it could result in a sharp and unpleasant poke in your insides. The second point pertains really to the rigidity of the plug. Because the shaft can’t flex around inside the body it makes its own path, and while this doesn’t affect the comfort of wearing it, it does result in the ball at the base coming out of the body at a slightly strange angle. The blue sphere does look quite attractive nestled between the buttocks, but with all these factors combined you really can’t sit down while wearing the plug.
Probably my favourite way to use the Mister Twister is for thrusting, as then you get to take advantage of the texture which feels wonderful as the muscle of the sphincter ripples back and forth across it. The only downside here is actually the shape, as I feel that the texture would be more enjoyable on a completely straight shaft rather than a tapered one. Something gets a little lost along the way as the muscle is constantly expanding and contracting, rather than staying stationary as it glides over the ridges, but this can be improved on by clenching the sphincter as you thrust. The other great thing to do is just to rotate plug whilst the muscle is sitting along the shaft, but this can be tricky to do if there’s lube on your fingers as the smooth glass ball isn’t easy to get a grip on. Either way, as long as the Mister Twister is moving you get the enjoyment of that texture.
Overall I’d be inclined to recommend the Mister Twister. It’s a really pretty piece, it has a lovely texture, and if you’re looking for a modestly-sized toy for some good anal sensations then it definitely delivers. If you want the same texture, but with a more traditional dildo shape, then the Swirled Blue by Don Wands might be a good option.
