I don't have much experience in using masturbation sleeves. I own a Fleshlight that I use on occasion. It gets the job done and feels better than just using my hand. That being said, the Tenga air cushion cup, in my opinion, is in a class all its own. The designers must have put a lot of thought into the material used and the shape of every nub inside this pint-sized-pleasure-producing-masterpiece.

The Tenga air cushion cup is essentially a plastic can with a soft thermoplastic elastomer (TPE) inside. The inside comes pre-coated with a generous amount of water-based lube. The whole package comes wrapped in a candy-store looking shrink wrap that is easy enough to be removed when you're ready to get busy. Because of the innocuous looking wrapping, I'm sure this would be a breeze to travel with. No one would really know or care to know what's inside.

When I unwrapped my Tenga air cushion cup, I was surprised at how much lube was already inside. When removing the snap top lid, I almost sent a good glob of the stuff flying. Note to other potential users: be careful when opening your Tenga.

The inner lining is white in color and is, through the manufacturing process, attached to the outer hard plastic housing (it is not a chemical bond that holds the two together - more on this later). The entrance is a small, about 1 centimeter diameter hole. But given how stretchy the inner lining is, this small hole can accommodate any sized cock. Unless you are longer than 8 inches in length and need deep thrusting to reach orgasm, don't let the Tenga's size fool you. I am somewhere north of average and fit inside just nice.

Pushing my cock through the small, stretchy opening sent a nice wave of pleasure through my body and having my cock surrounded by all that Tenga had to offer made me feel like I was inside a real vagina. The toy has a very organic give and take feel. If I removed my had it wanted to push my cock out slowly, but gentle pressure gets you right back in. I (unfortunately) came pretty quickly (3-5 minutes) as I thrust my cock in all manners (fast, slow, hard, soft). Because Tenga feels so good, I took some time to stop and give myself a moment to wind down before continuing. (I wish I had taken more breaks than I did because this toy really is worth savoring). From my point of view, the sensations I was getting were so nice that I wanted to prolong my masturbation session, but all good things must come to an end and I eventually lost my load.

The Tenga air cushion cup is labeled for one use only for good reason. The way that the item is manufactured makes it near impossible to clean. Because of the way the inner liner is attached to the outer plastic, it cannot be removed without tearing. I tried doing this because I desperately wanted to use my Tenga again, but ended up damaging it in the process. There is also some sort of spongy material near the entrance - you can't feel it while masturbating, but feel around with your fingers and you'll find it - this, I think, is a reservoir for the lube. Long story short - you can try to rinse the interior out with copious amounts of water and apply your own lube later, but because of the myriad air pockets, nubs, and other features that give Tenga a very organic, lifelike feel you probably won't ever get the inside completely clean.

The Tenga has a small sticker at the end meant to allow you to decide if you want more or less vacuum as you thrust. I opted to remove the sticker - it not only felt better, but it eliminated a funky sounding noise every time I pulled out.

All in all I would highly recommend this product to anyone looking to get into masturbation sleeves. The one time use is a bummer, but for the sensations you get it might just be worth it.

There is not anything to say in the way of a follow-up. Because this is basically a (freaking amazing!!) one time use device, I no longer have it around. I would, based on the sensations this magical little sleeve provides, still highly recommend it to anyone with a penis.
