i like a great vein...not to the point where the cock looks like its been in the free weight room...but nice clean veins.
here is my vein thru my Levi's.
and i love to suck a breeder with a great top vein as well..feels great on my top lip..
this is what makes sex so great..VARIETY...not all of us like the same stuff...so the hunt for the right partner makes the exploration all the more interesting.
