I have one of those toys. It's known as The Tube. You can get them through Amazon.com. They're about $12, pretty cheap as sex toys go.
I use skin-care lotion as lube. The tube feels cold and clammy at first, but it soon warms to body temperature. When I start putting out precum and it mixes with the lotion, it feels awesome, like liquid velvet. Unlike the style this guy uses, I prefer to cum with my penis inside the tube, as though it's inside an ass or vagina. But to each his own.
