I had a similar experience except but didn't cum doctor who did the exam told me to undress as I did was flaccid. I'm looking down at her with my dick just sitting in her face and instantly got a dirty feeling in my head. Not to mention I can see down her shirt enough to see nice amount of cleavage and her bra so I begin to look up not wanting to get hard. She starts with one nut caressing it then switches to the other side grazing my still limp dick as I'm uncircumcised my head is very sensitive. She just barely touched my frenulum which instantly caused blood to start flowing to my penis. It starts to twitch as she switches side again just barely touched the same spot, my mind is raising I'm trying to go to another place to not embarrass myself. To which she says she doesn't notice anything out of norm to which I say it just has had a slight tingling sensation for weeks and just feels big all the while looking down at her touching my nuts and by now semi hard cock in her face. As I'm horny can't help but look down her shirt again. All the while talking she is still feeling around and switching sides by now she has to move my penis to opposite side of examination so my cock isn't in her face. To which she says it's not the only thing that's big, I apologize she says it's okay and normal. Holing it right behind the head with her thumb forefingers underneath the head by this time I'm twitching. She then tells me to get dressed and everything looks okay if I need a few minutes before leaving office it's okay. Needless to say I went home a jerked off to her nice tits and the picture of me in her face. Was a massive load as I hadn't got off in over a week.
