I had a mildly itchy cock and went to see my friendly regular doctor. Our family has gone to him for years and we all liked him. When he asked with a raised eyebrow what I'd been up to, I told him nothing special which was the truth. He got me to strip from the waist down and lie on his examination table. He talked all the time I was getting ready and I noticed at once that he didn't put on rubber gloves to examine me and he avoided eye contact, both things I thought odd for an intimate body process. He squeezed my cock between his bare fingers and rolled back my foreskin. I hadn't been touched like that by another male since I was a teenager. «There's a slight inflammation, nothing serious,» he said, peering closely. He kept hold of me while he spoke and I struggled to stop myself starting to get hard. «You been masturbating a lot,» he asked as he weighed my balls with his free hand. His question embarrassed me and I mumbled that not more than usual. «Use lube if you don't already,» he said. I thought that would be the end of it but instead he said: «While you're here, I should check your prostate.» I wanted to say no but didn't want to look stupid so I let him tell me to get on my hands and knees on the table with my bare ass open for him. He got a bottle of lube and squirted some into my asshole and put his finger into me, still without putting on a glove. He kneaded my prostate insistently and that was the end of my efforts not to get an erection. I love being fingered and get my wife to do it to me as often as I can persuade her. She gets her forefinger deep into me and I wank while she does it. «I'm not embarrassing you?» he asked. «I said no,» and his finger went a little deeper. «Play with yourself if you want,» he said, «or I'll do it for you if you prefer.» I told him yes and twisted on to my back. «I've never been masturbated by another man before,» I told him. «It feels good.» It was true. Now that it was happening, I really liked the expert way he stroked and squeezed me. It didn't feel wrong at all. «You have a lovely cock,» he said. «You shouldn't keep it to yourself.» He said he would finish me with his mouth but I didn't last long. The roughness of his tongue on the sensitive underside of my glans made me explode immediately. Man, a whole new world suddenly opened up to this straight (I thought) dad.
