This is something I've never told anyone.
When I was seventeen I had to have a particularly difficult set of stitches out. I hated the doctors, full of old people, but my doctor had not long changed and I found the younger guy, a locum, to be a lot more relaxed, which helped to relax me. I was told it would be a little painful and obviously a little embarrassing as the stitches were right under my ball sac (kicked with a set of rugby boots, long studs. It fucking hurt). And being a reasonably well endowed guy, I knew my cock would be right in the way.
I've always hated blood (I know it's stupid, but hey), so I asked him if I could have a sheet put over where he needed to take out the stitches. He agreed and I lay semi naked waiting for him to begin. The thing was I felt my cock rising even before he crossed the room start. By the time he was about to begin taking out the stitches, I was fully erect.
He told me because my blood was pulsing around the area he needed to take out the stitches, we'd either have to wait or he could assist me in releasing my erection. Totally embarrassed, I just wanted it all over and done with. So thinking he was going to stroke my cock until I cum, I said okay. After all he was doctor.
Only it wasn't his hand that took hold of my cock, it was his warm wet mouth and if truth be known, it felt fucking amazing. Because of the sheet I could see what he was doing, but I could feel his tongue swirling around my cock head. With each bob of his head, he took in more and more of my cock until he had three quarters of it sliding down his throat.
Moving the sheet, I just had to see him sucking on my cock and by the looks of it when I did, he was enjoying sucking on my cock, just as much if not more than I was having him giving me head. Like most of my girlfriends before and since the doctor, I took hold of his head and began to fuck his face. It wasn't too much after, maybe five to ten minutes as I'd begun to fuck his mouth, when I felt my cum rising. Telling him, I thought he might pull away and jack me off, but instead he sucked in my cock even more. And before I knew it, I was pumping my cum down his throat, and he was greedily swallowing the lot.
As a kind of anti climax, the stitches took no more than a few minutes. And shaking his hand, I also took a piece of paper with his mobile number on it.
The doctor and I met up on five separate occasions, but never back at the surgery. Each time we met it was either in his car or one occasion he drove us out to place he knew. It was a wet day, but I still really enjoyed him sucking on my cock as we stood under a huge oak tree. The difference that time, is he brought condoms and lube. I fucked him as he leaned against the oak tree, and for the first and only time in my life, I came up a mans arsehole and loved it.
We didn't see each other after that, as I began to date a very pretty and extremely horny girl. He is so far the only guy I've ever had suck me off and whom I've fucked.
But that's not to say he's going to be the last, and more to the reason why I'm here. I'm engaged to be married next spring. She's a very good looking young woman, and she's very good in bed. But then her younger brother is also very good looking too, and only recently told me he was bisexual. He also told me as he tried to slip his hand into my shorts, that he'd love me to fuck him. So far I have resisted him, but I'm not sure if I could carry on resisting him, especially as I know he has one hell of cute looking tight arsehole.
