That's one of the coolest ways to do it. Tattoo up and have all your business colleagues have no idea about your tattoos because it's covered up. It becomes your secret that nobody else knows about that you share with significant others and friends. Then if someone crosses that border after 5 years of knowing you, you have a t-shirt on at a bar or something and they go whoa when did you get that? 10 years before I knew you. WHAAAAAAAAAAAAAAAAAAAAT. head explodes
Also, it makes it easier for you since you can just be staring at her boobs or butt all day and she'll ask "are you STARING at my butt?". "No I'm just marveling at your tattoos of course! wink wink nudge nudge".
