You turn up for your long overdue physical exam to find you have a new doctor - a hot young woman wearing a black bra under her lab coat. You're so embarrassed to be here for a prostate exam, especially as you've started experimenting with anal play in the past few years. Will she be able to tell? Are you going to get excited? This is so humiliating as you start to grow semi-hard as she strokes inside you with a gloved hand. You might not have to worry about your own reaction though...as she can tell exactly who and what you are, and has plans of her own...
But it doesn't help that you'd forgotten about the timing of this medical appointment and started a jerk-off session that you didn't manage to finish right before attending. That throbbing, nagging feeling of what was left incomplete is pulsating in your cock right now as you notice that my cleavage is somewhat on display, as you notice that I'm smirking at you looking at that.
