Preferably with a hot girl's finger.
When I was 17, I had some stomach pain in the appendicitis area. So I go to get it checked out and it's this 9.3/10 persian babe, golden skin, long dark hair, lucious lips, firm medium sized tits and round apple bottom, who is the surgeon who is going to make the call. So she presses here and there and seems content it isn't appendicits.
Then when I think everything is a ok, she says 'oh yeah, just one more thing, could you please lower your pants for me'. I hesitate. She goes on 'Yeah, well, you can't really visit the gastro department and not get a rectal exam'. So well, I think, got to do what you got to do, right?
So, I drop my pants and make a motion to turn around, but here's where it's weird. She says 'no need to turn, just stay right there'. Then she drops down to her knees, her face merely inches from my cock. She proceeds to lube up her finger, while looking me straight in the eye, then grabbing my ass with one hand and moving her other hand under my crotch, her face now practically touching my dick. I can't help but get a semi. She notices but doesn't seem bothered, in fact she giggles.
Then she does it, she penetrates while at the same time gripping my balls with her free hand. She looks at me wantongly and she starts moving her lips closer and closer to my erect member. Then suddenly it knocks on the door and she quickly withdraws herself and gets up.
I never saw her again.
Ever since then, I've had a fetish for nurses and rectal exams. It's an expensive hobby unfortunately. None of my girlfriends have understood it and escort girls know how to get paid.
