This sleeve is made from soft and plushy TPE. TPE can vary in firmness, but this is as soft and supple as human skin. It stretches, too, and perfectly mimics the tautness and tightness of human flesh.
If most masturbation sleeves have a flaw, it's in size. The majority are literally 'sleeves' and have a hole at both ends - meaning a well-endowed guy like me 'pops' out of the opposite end. The wonderful thing about the Hotmilk is that it's got a closed end, which stretches out to accommodate any length and means your whole shaft is stimulated whether you're on the in-stroke or out.
It's also seriously small and discreet - perfect for traveling.
Simplicity is the secret here. The sleeve is nothing but a tight hole to fuck. There's a lot of complexity to making something so simple work, however, and the Hotmilk achieves that balance. The give, softness, ease of insertion and ease of grip make this, quite simple, one of the most easy-to-use and easy-to-enjoy sleeves available - and one that's quite unprecedented for the price.
You can clean the Hotmilk with hot water. It's easy to turn inside out and pat dry with a towel, which makes it an absolute doddle to clean and keep. In this respect, it beats the 'superior' products like Fleshlight and Tenga Flip Hole hands down.
Once it's dry, you can return it to it's box ready for next time.
Hotmilk comes wrapped in a plastic bag, in a box the size of a carton of toothpaste (emblazoned with a sexy looking manga chick.) There are no instructions, but if you can't figure out how to use it you obviously went to the same Sex Education classes as Bristol Palin.
I have used literally dozens of cheap sleeves in my time and never TRULY found satisfaction with any of them - until I found Hotmilk. For sheer sensation, I'll still pick a Fleshlight - but four times out of five I'll masturbate with the Hotmilk now because it feels great and is so quick, convenient and easy to enjoy.
