After clocking in to begin my shift, I looked at my list of patients for today. My first patient was a young man with an erection problem. Once he got an erection, it would not go down, even after multiple orgasms. An interesting case. Of course, I didn't believe him, and wanted to see this with my own eyes. I had him sit on the exam table and began to ask him some questions. I could tell he was nervous, and I explained to him in general terms what we would be doing.

I asked him to go behind the curtain, take off his clothes, and put on one of the gowns hanging up. "The gown can go both ways, so please put it on so that the front is open. Take off your shoes and socks as well. I plan to do a complete medical checkup since it's been so long since your last."

He reluctantly went behind the curtain and after a minute or two came out wearing the gown. He had the front tied tightly together. After he sat back down on the exam table, I went over and untied his gown. As I pulled the front open, he put his hands down over his penis.

I told him I would start the exam off by inspecting his genitals. I pulled his hands away to reveal an extremely attractive member. I took hold of his penis and gently pulled the foreskin back. He had a very prominent head and an unusually large glans. I told him to lay back and relax. I began to massage the area with my fingers and immediately felt his penis begin to enlarge. I could tell he was embarrassed, having a strange woman massaging his cock. He had no control over it. After just a few moments, my massage had given him a full-on erection. I proceeded to start jacking his shaft, rolling his foreskin all the way back then up over the head. So far, he had no pain so I continued.

I hadn't planned to bring him to orgasm until after two or three appointments, but no man could resist the sensations I was providing him with. I had gradually increased the pace, jerking him from the base to the top of his shaft. Before I knew it, a fountain of semen erupted from his cock. As I furiously pumped his big, thick cock, spurts of cum continued to forcefully shoot from the tip. I was unprepared for this as his cum flew everywhere. Despite this, I continued to pump his cock until he had fully emptied his balls.

By now he was on the exam table gasping for breath. I took my hand off of his penis, which had maintained its hardness, sticking straight up. It looked out of proportion compared to the size of his body. I had cleaning supplies ready, and while he recovered, I started to clean. Semen was everywhere. All over him, all over me, on the exam table, and on the floor.

While I wiped up his cum, he started to apologize. I walked back over to him an took a hold of his cock. I told him there was no need to apologize, as what happened was normal and expected. I told him there was no problem with his erection, as his work had ended up everywhere. He pointed down to his cock, which was still rock-hard and throbbing. He said his cock only got soft after cumming multiple times, and that it is too much for most girls.

I climbed onto the table with him an kneeled between his legs. He was indeed still rock-hard. I grasped the base of his shaft, leaned over and took the large head of his cock into my mouth. He loudly drew in his breath as my lips closed over his shaft. I ran my tongue around the head where I knew he was super sensitive. I lightly jacked the shaft with one hand. I loved to suck a big cock. Especially one with a large head like this one. I started to apply more pressure to the head, letting my lips slide down onto his shaft. I began to deepthroat his cock as it swelled to an even larger size in my throat. I then backed off a bit and slowed down. I wanted this to last. I was in heaven with his big cock tickling my throat.

I sucked his cock right to the balls and then started bobbing my head up on down as fast as I could. I felt him place a hand on the back of my head, forcing his dick deeper down my throat, forcing me to choke and gag on his penis. I loved the feeling of his thick cock filling my entire throat, putting my mouth to good use. It didn't take long to achieve my goal as a massive explosion of cum shot down into the back of my throat. I could feel each spurt slam against my throat as his cock pulsed and his body bucked in pure ecstasy. I greedily swallowed one of the biggest loads of semen I had ever received. This surprised me, as I already thought the had cum so much earlier.

I raised my head and let his cum drip from my mouth and onto my chin. I complimented him on his impressive cock, and how much I had enjoyed him stuffing my throat. I felt myself craving for more, to have it inside me. I had never fucked a cock as large as his, but I was dying to see what it would feel like.

His cock was still leaking semen as I leaned over and licked it clean. I let his cock slip into my mouth again, rolling my tongue over the head and sucking it lightly. I jumped off the table and took off my clothes, before climbing back onto the table and giving him about a minute's worth off cock sucking and deepthroating. I then turned around giving him a full show of my juicy, plump ass. I once again told him to relax, and to let me control the penetration, otherwise his big cock might hurt if he gets to excited. I placed the entrance to my vagina directly above his massive, throbbing cock. I held my lips open as I guided him into me. I began to slide myself down onto him, taking his head inside. It felt amazing and my pussy was already soaked, but I knew I might be to tight for him to fit. Despite this, I was determined to have him inside of me, stretching me out with his massive cock. I rocked up and down on him, taking more of him in me with every stroke. I could feel him eager to get all the way inside of me, to penetrate me. It was hurting me, stretching me open more every second, but I didn't care.

Finally, I eased myself onto his cock, taking about half of him in me. He groaned in ecstasy, but I am sure it felt better for me. His cock was so big, and there was still plenty more to take. I wanted it all, so I began to slowly bounce up and down on his cock, gradually letting him in a bit further every time. After a couple more strokes, I was taking his entire length. Each time he bottomed out deep in my pussy I felt a stab of pain, but I was loving it.

I began pounding up and down on his glorious cock, letting him explore all of me. I was riding and twerking on his cock as furiously as possible, craving to be filled. I was on my third orgasm when he let out a scream of ecstasy and poured a load of semen into me. I looked down and could see semen running out of me and onto his balls.

Unexpectedly, he smacked my ass and bent me over the table. He was taking complete control. And I was not going to stop him. He bent me over, raising my ass in the air. I felt his large head against the entrance of my pussy for a brief moment, before forcefully shoving his entire cock into me. I shrieked in pain as I took his entire length. He began pounding away, each stroke more forceful and pleasurable than the last, his thighs clapping against my ass, causing it to jiggle with every thrust. He took my arms behind me and raised me up, me begging for more, for him to fill me up. He reached around and started grabbing my boobs as he continued to plow me from behind, splitting my insides. I felt his cock pulse, before feeling him pump rope after rope of his seed into me.

We laid there together like two exhausted lovers. I glanced at the clock on the wall and saw that our time was almost up. I slowly raised myself up and felt his cock slide out of me. I hopped off the table and bent over, taking him into my mouth as I sucked his cum and my juices off. I grabbed his cock and began to deepthroat him again. It didn't even take two minutes before I was taking another load into my throat. I was surprised at how he could go on for so long and still cum again and again. As he once again emptied his insides, I finally felt his cock go soft.

I was left speechless. I had just let a patient fuck my brains out with his massive cock. And I loved every second of it.
