Zack been on bottom duty with the straight guys for far too long, and he is a most excellent top as well. He in fact excels at everything he puts his mind and cock too.
I thought he and Saber had similar builds, though Saber is much taller. They both have nice uncut cocks, so if you like extra skin, you should be a happy jacker.
