Custom video. You're at the end of your annual checkup when you bring up a weird sensation you've been having to your doctor. But your penis has to be fully erect to show what you're referring too. After first you try stroking with her in the room but it doesn't work so she leaves and comes back. You're only semi erect, you need lube. She tells you to use your own saliva but you've already tried. Maybe you can use hers? She's shocked and immediately says no. That's unprofessional but eventually reluctantly agrees. But you need more, you stroke as she spits on your dick. She quickly examines you but you're loosing your erection. She begins stroking you reluctantly and as professional as possible but you need dirty talk. She loses it, she can't do that this has gone too far! But does it anyways. She gets into it and strips her clothes off and rides your cock with degrading dirty talk.
