Have a big one and think our regular sleeves are a bit snug? Or do you want to lessen the stimulation level to train yourself to last longer? You’re in luck! Our Stamina Training Series sleeves are 50% wider to accommodate larger penises and offer less stimulation due to their wider internal dimensions. The internal patterns match those of our dependable standard series of sleeves, offering realistic and pleasurable stimulation to those who desire a looser fit. So break out the Fap Lube, pick up a stamina training sleeve, and get ready for an extra long fun session!
The sleeve that came with the machine was unbelievably tight. It got the job done, but felt less like a blowjob and more like sticking your dick into an angry little robot. This sleeve feels much better, almost as good as the real thing. Just be careful if ordering outside the US. The shipping box was discreet, but the customs form had it labelled as "replacement sleeve for motorized massage machine" along with some "water based massage oil". Wouldn't take a genius to figure out it's spare parts for a wank robot
Feels almost like a blowjob
The not so subtle customs declaration. Though not sure what else you could really call it...
Worth it if you find the original sleeve too tight/over stimulating
The device could get the job done with the default sleeve, but it was not particularly comfortable, and full insertion on each stroke required some force. As such, it had sat unused in the cupboard for months. The new sleeve is a significantly better experience. It is not noticeably wider visually, but is much softer, which is especially important where the canister narrows. This is the sort of improvement over other options to justify the additional clean up effort, and is likely to get much more use. Company took a long time to respond to feedback with an upgraded product — which really should be an option at device purchase rather than an additional cost — but did an excellent job eventually.
Comfort, softness
Opening could be bigger — this is still not super easy to get in to — and additional cost is high given international shipping
Makes the machine worth using again
I got the newer ones which I found out on reddit were injected but the old ones were poured, so this is only valid at least for these newer models sold at the end of January 2025 and onwards. The inner textures on these are much more nuanced than on the normal sleeves which underwhelmed me. I took advantage of a 3 unit package deal . They were better than expected because the website did not do a great job of showing textures.
Much more nuanced textures than the originals
I would even try a even looser model if possible like a DOUBLE wide haha
Good for stamina training
