My one time was a few years ago.
Had badly twisted ankle. Very swollen. Had it strapped and on crutches. A few days later wife was just going out for her morning walk when male nurse turned up. Wanting to check up on me. I was still in bed, naked as always. She showed him in and he told her not to worry and go for her walk. I told her not to hurry and to do her full hour. She gave me a kiss and left.
I slipped my leg out from under the duvet. He asked if i was shy. I replied no and he promptly pulled the duvet off of me. He said that he could see from my all over tan that indeed i was not shy. He asked if i would be more comfortable with him being naked. I replied that he was more than welcome. He quickly striiped off and sat on the bed, his twitching penis matching mine. He settled my leg on his thigh and took the strapping of. After a quick examination he cleaned it with some medical wipes and redid the strapping.
Stroking my thigh he asked if i was getting any pain. I replied sometimes but a quick rub soon relieved it. He laughed and said that often worked but a slow rub was better. I said yes, i did prefer a slow rub. He retrieved some more wipes, held my erection and slowly cleaned me. He cleaned himself and got onto the bed. I slid down a bit and he began to stroke my cock. He soon moved down and slid his mouth over me. As he slowly began to suck i reached out and began to rub his cock.
He was soft and warm and it didn't take me long to shoot my load into his throat. He continued sucking for a bit and i pushed him down so that i had a better angle to wank him. It took a little time but he eventually unloaded a couple of strings onto his chest. We played with each other for a few minutes than he cleaned me and himself, got dressed and left.
