A bull who can do a tattoo?

I am just thinking of dipping my toe (so to speak) into the real cuckold world.

My wife is talking about getting a small tattoo near her pussy. Thinking about a guy tattooing around her pussy got me very hard indeed. Then I thought it would be awesome if a bull did the tattoo. I envision talking to the bull during the lead up time to the tattoo appointment about how he was going to enjoy seeing her pussy and touching it as much as the procedure allowed him to do. On the day of the appointment, I would hand over the money for the tattoo to him then hold her hand while she received the tattoo, so I could watch very carefully. I know this is very tame for this board, but I thought it is a first step I could take.

Is there anyone out there that fits the bill in the WNY area?
