You are addicted to porn, especially big boob porn. Your doctor has run several experiments on you and has found that your brain receptors really light up when you see tits. As an experiment your doctor pulls her big tits out to see your reaction. There really is no hope for you is there? Looks like you’re going to need lots of therapy if you’re ever going to overcome your big tit addiction. Thank goodness Jackie is an amazing doctor, with an even more amazing rack!
