Oh shit those condoms are kind of hot. I was thinking about the jet black ones as well, didn't know they had those see through ones. I might start using condoms now! jkjk
I think you're talking about a cock sheath - vs- a black condom.
A cock sheath is typically solid black latex with an attached ball sack, where as Tuxedo brand condoms are a transparent black colored condom. Tuxedo's are so much better than the colored condoms. I don't know who thinks a green tinted cock is sexy...ick.
I have to say I like them both (I have pics of me wearing and working on cock sheath in my galleries) but with the cock sheath i have to wear a ball stretcher to get my balls in (otherwise the senak back out again.)
There is also a thicker piss sheath that has a piss tube in the end.
One of my FB's is very, very, thick (a hot fucking German guy) and he claims that cock sheaths explode on his cock once he gets hard. I keep telling him I want to see it happen but he won't do it. I'm sure it's not comfortable for him. I think it would be soooo hot to see a cock get so big it explodes out of it's sheath...that's power!
