After reviewing your CBT scan Doctor Bishop has decided that you need a pressure release. You’ll have to jerk off while she watches closely, but for ethical purposes you need to ruin it by letting go and not enjoying the orgasm. Throughout the procedure she gets a little carried away watching you pump your big dick and decides to help you by stripping down and instructing you how to stroke it. You don’t get to enjoy your orgasm, but that doesn’t mean she won’t as she fingers herself until she cums.
