Girlfriends older brother is a tattoo artist. Was talking to him one day and he told me about how much it sucks inking an obeast. Apparently the skin has a different elasticity or something that makes it way harder to get the tattoo done right. He also told me he gives hams a higher rate to justify the extra effort and difficulty in addition to the upcharge for the bigger size to fit their bodies. Basically he's making extra money by being a shitlord.
