So today I [27M] went to the doctor for some routine checks. I have asthma and recently went through a really tough flu so I needed some meds, thing is I also have been looking close at two small pimples in my testicles, because they've been there forever but, as of late, they've grown and changed colour. So once I had finished the usual checks I've said to my doctor [36 apprx. F] that I was worried about that. She's asked me to undress for an inspection and suddenly I felt so embarrassed that I thought to myself an erection was simply impossible, but... It wasn't.

As soon as she's put a hand on my balls and got her face to bare centimetres of distance from them I've felt an arousal rising abruptly, I could not even believe what I was feeling and I was cursing my body for this treason, but it was unstoppable.

To try and make things better I've reached my penis with my hand to hold it, as she was doing so and I felt this was the problem, but she was so focused on the exploration, doing all sort of massages and taunts with my balls, she hasn't noticed, so we've remained with our hands together holding my dick.

Maybe less than a minute has transcurred when I had a complete and splendid erection which, again, we were kind of holding together so she's felt how all of a sudden the softie thingy she was touching has grown and hardened between her fingers, and has become warm and veiny. At that moment she has looked me up in the eyes, seeing my dick completely hard already in her hand, making an expression of absolute astonishment and I really thought my heart would stop.

I was about to say something but she's raised her hand, releasing my balls, and made a gesture for me to keep quiet, and in that moment she has started to massage my dick really, really slowly. Due to the gloves the feeling was extremely smooth but lacked lubrication, so she has gotten her lips super close to my cock, almost touching it, and spit on the head of my dick, now her hand went up and down with ease.

Without even rasing her hand from my dick, she has untied the buttons of her blouse and let her bra out covering a pair of medium sized breasts jiggling a bit, finally reaching one to pull it out. The amazing massage has kept on and on while I reached to her naked tit to play with her hard nipple, until eventually I've grabbed her ass and I've started masssaging her pelvis over the clothes.

And like this she's been jerking me, keeping me quiet with a finger in my lips when I moaned, keeping herself low biting that same finger when she was about to moan because of my hand in between her legs. Until I have ejaculated, which she has anticipated really well, (doc things I guess?) using a nap to get all the cum collected.

After this she has examined the cum, I'd swear she has smelt it, and finally has said: "Nothing painful down there or you would have complained for sure, no pain ejaculating or you would have complained for sure, nothing that stands out in your jizz as I see it, so apparently those are a pair of simple and harmless pimples, they should go as they have come."

I've said "Thanks, bye" and I've left
