When I was in school, my favorite English professor (and the favorite of just about every hetero or bi girl on campus) had tribals on his biceps. You could only see them when the weather was hot and he was wearing short sleeved shirts. They’d just barely peek out. The fact that they were partially hidden may have added to the appeal, making the mind wander about what else may have been hiding under his clothes.
…excuse me, I’ll be in my bunk.
