Jack slowly drifted into that half awake, half asleep state where you're not entirely sure if you're dreaming or not. Must have been a good dream, cos he was sporting an erection that was as firm as he could remember in a while...and it was being grasped tightly as a the familiar feel of pussy slid slowly up and down. A delicate moan of pleasure confirmed he wasn't alone, but his hands moved to hips then the waist of the woman on top of him. He couldn't remember how they got here, but damn if this wasn't a helluva way to be woken. He couldn't quite open his eyes yet, but he felt the weight shift above him and the unmistakeable presence of a nipple pressed against his lips. He opened his mouth, rolled his tongue around and was rewarded with a very pleasant moan of "oh Jack". He sucked on it briefly, and the nipple was lifted away and replaced by its twin, eager fur attention. Now his eyes opened and saw the beautiful full figure of a blonde woman slowly fucking him and having a very nice time doing it...and damn he was hard and enjoying it like he hadn't in a long time. But how did she get here..."Mr Spencer...Mr Spencer"

Jack awoke and saw the smiling face of the young blonde nurse carefully wakening him in the waiting area. "You seem to have dozed off". Jack mumbled an apology and followed her into the consulting room, the relic of his vivid dream being the erection which he was acutely aware of, and the realisation that he was following the young woman who he had just vividly imagined fucking him. His face flushed with embarrassment and he assured her he was feeling okay.

Jack sat down in front of Dr McKellar and waited while she read his notes. "So Mr Spencer, the scan and the test results confirm you have the problem we suspected. In layman's terms, the plumbing from your kidneys to your penis is narrowing and that explains the problems you've experienced urinating." Jack nodded, understanding what he already knew, that passing water was excruciating at times for him, which had a side effect of virtually killing anything resembling a sexual impulse in his body. At 52 and widowed, it wasn't as if he was letting anyone down in the pleasure department, and the health problems were compounded by his excess weight.

"On the plus side, we have a couple of treatment options, each with their own risks and possible benefits. We have a surgical option, which has around a 70% success rate, however there would be a need for ongoing medication as well as possible rejection of the artificial replacement tubing. We do however have a trial that you might be suited for". Jack perked up at this. He was dreading the surgical option, and Dr McKellar spent 10 minutes explaining the alternative approach which was a combination of gene therapy and some hormonal treatment. This would involve arthroscopic surgery for the beginning, followed by several weeks of appointments scans and medication. It had the benefit of virtually eliminating the rejection risk, and so Jack quickly said yes to the trial therapy.

Jack was given some medication to start taking immediately, and had a surgery date in 10 days time. Debbie, the young nurse smiled and confirmed the arrangements and Jack felt his cock stirring again. Time for a swift exit, a return home and an hour of reading about the treatment was swiftly replaced with a search for nurse themed porn. Oddly none of that seemed to get him aroused, but a glance at the medication bottle which he had already started taking, reminded him of his earlier day dream, which he realised was fantasising about the blonde nurse, and again, his cock responded and a few short minutes later, he shot his first load in weeks, then grimaced as the discomfort in his cock overtook the fantasy.

Over the next week, Jack took his medication as prescribed, got out to do some walking and cycling exercise to try to shift some of his excess 35 pounds in fat, and found his dreams resulted in some very detailed sexual fantasies. Some were of his favourite nurse, some of Dr Mckellar, who though in her early 40's wasn't unattractive, and seemed to be wearing very short skirts and bending over A LOT...at least in his morning arousal.

Jack's next step was a visit to a counsellor, to make sure he was ready for the procedure. He arrived at nondescript office, confirmed his appointment to the receptionist (who was in no danger of prompting a sexual response), and sat browsing his phone.

Angela Collins stepped out of her office. He was immediately struck by her poise as she invited him in. She was a woman probably in her late 20's or early 30's, tall, slim and a cascade of red hair that draped below her shoulders. He immediately warmed to her, as they chatted and Angela spent the next hour with him making sure that Jack was prepared for his procedure. He was distracted throughout by her large green eyes and found the time flew past.

"Jack I think you're all prepared for the procedure. We will do some follow up sessions after to see how you're feeling, and Dr McKellar and I will provide the study with a complete view of how your treatment is progressing, both physically and emotionally." Jack smiled and told her he was looking forward to it.

The next morning, Jack's morning fantasy saw him putting the couch in Angela's office to some unconventional use and he began to wonder what exactly was in 'Combined therapy 221' that he had been taking over the last week, but he knew firstly that his discomfort in urinating was reduced, and that his libido was significantly revived, with the morning erections a daily occurrence, and he was masturbating a couple of times a day, something he hadn't done in a very long time.

The date of the procedure swiftly arrived, and Jack was invited a quiet private clinic in a leafy suburb. Clearly significant money was backing the trial, and he spent the day being measured, prodded, poked and scanned. Blood, urine, stool and semen samples also had to be provided. Jack was just trying to figure out how to get in the mood, when he spied Debbie in the area outside his room, the door not yet closed over. Out of scrubs and wearing a blouse and skirt, Jack got a much closer look at her curves, and in no time Jack was erect and slammed the door shut to furiously masturbate and provide a prodigious semen sample. He couldn't recall his cock feeling so hard, and he could have sworn it felt bigger in his hand too.

A tap on the door and Debbie's head poked around to ask if he needing anything to get started. Jack held out the sample jar, and it provoked a smile and an appreciative glance at the volume it held. This was the end of a long day for Jack, and with surgery scheduled for the following morning, he was packed off to his private room with strict instructions not to eat or drink, and specifically to avoid ejaculating. Jack knew he would find the latter to be difficult, especially with Debbie in his thoughts, but eventually, Netflix brought tiredness and sleep.

The following morning Jack woke just as he could see the sun rising through his window, and as usual of late, he was dealing with a severe case of morning wood. While enjoying the moment, his door swung open and in came two nurses to prepare him. One of them started to lather a shaving brush, and Jack immediately realised it wasn't his face that was going to be prepared. They peeled back the sheets whereupon the obvious erection was poking up against the surgical gown, Neither nurse batted an eyelid as they carefully ensured he was hairless from his knees to his stomach, although if the bed could have swallowed him whole, Jack would have been grateful. He remained scarlet cheeked as they left, though it didn't do his ego any harm when he thought he heard them make appreciative noises about the girth of his cock, which seemed to have little inclination to return to a flaccid state.

Before long he was being wheeled to the theatre, the blood having been restored to other parts of his body and the final discussions prior to the local anaesthetic being applied. Jack knew the surgery itself would be uncomfortable, and the hospital let him listen to a playlist of loud rock. It only took about 30 minutes to complete, and before he knew it he was back in his room under close observation.

Jack awoke a few hours later, and felt surprisingly spry, the effects of the anaesthetic worn off and a general ache in his groin being the only indication of it having taken place, that and the complete absence of pubic hair. Nurses came and went about their business, with a visit from Dr McKellar later on confirming that it had went well, and as planned a few days of close observation would ensure his wellbeing.

The following morning, Jack found himself in that lazy aroused dream state that had been his experience almost from the day he started taking the medication, but as he was giving Angela a very thorough fucking on her desk, he felt his climax and was suddenly very aware of that having happened in reality. With no choice he buzzed the nurses station, and in came Debbie. Turning a shade of pink, he blurted out that he seemed to have had "an accident" and could he get some tissues to clean up. Instead Debbie pulled back the sheets, lifted the gown and saw the result. She actually seemed pleased, and made sure to scoop some up into a sample jar, as well as applying a very through washing on Jack's groin, while other nurses changed the bedding. No one seemed perturbed by this, though Jack put it down to their professionalism. Debbie handling his cock did nothing but cause him to become erect all over again,but this was followed with some measurements and a call to Dr McKellar.

Jack waited for over an hour until she came to speak to him. He was genuinely concerned he might have done something to harm his surgery, but the Dr seemed happy enough. She asked to see his groin, and again a firm erection was on show.

"We've checked the semen for traces of blood, and there are none, and that's great news. However we have to take care of your persistent erection or that could be potentially damaging. Our team will help you to make sure we achieve that. If need be we can use an injection to reduce it, but our preference would be to do that by more conventional means"

Jack paused for a moment. Did she just say what he thought she had said? He was to masturbate himself better? "We can provide materials to assist Mr Spencer, however you will have to be observed throughout and we need to check each ejaculation to make sure no harm has been done."

At this point Debbie came back into the room with a chart, clipboard and several sample jars. The Dr left, and Debbie quietly approached the bed. "Jack I have to observe you to make sure we properly understand your reaction to the therapy in full. I'm sorry if that makes you uncomfortable..." He grimaced and his iPad started to slide off the bed, but the young nurse caught it. The screen opened to show a sub Reddit filled with nurses showing off their bodies under scrubs and uniforms. It had formed a fruitful part of Jack's masturbation material over the last few days, but now it was right in front of the subject of his fantasies. "Do you like that..." Jack stammered and was lost for words "...naughty nurses who go naked under their scrubs?" His erection now raged in the moment, even though he thought he might pass out with embarrassment. He was sure she would storm out the room, but instead stepped away and carefully locked the door.

"We're going to have to take care of you Jack, and I think I know how to do that." She reached for the hem of her tunic and slowly slid it up her body. Jack could not stop his hand sliding up and down his cock, as more skin came in show. She paused briefly with the tunic hem just under her large breasts, and with a wink, lifted it further to perform a "titty drop" that seemed very popular on that page. The tunic was lifted completely off, and Debbie's magnificent figure was on full display, with large nipples suggesting she might be as aroused as he was. She started to fondle her breasts and play with her nipples, gasping as she tweaked then between her thumb and forefinger. Jack grabbed a sample bottle in one hand, and pointed his cock into it as he exploded 4, then 5 times half filling the jar.

Debbie popped the cap on, jotted the time on the label and made notes on her chart, her breasts moving as her writing caused to jiggle in a way that wasn't helping Jack regain his composure. She made to grab a wet wipe to clean his cock, then paused, and winking at him then leaned forward and licked it clean. He felt the warmth of her full breasts pressing against his legs, the nipples still firm and he could tell exactly where each was.

She leaned in and went beyond cleaning the head, her tongue now running the length of his cock, then he was swallowed in felt her suck deeply. "Oh fuck that's fantastic" he gasped and within a minute he could feel his body preparing to spout another load. He tapped Debbie's head, she paused, picked up a jar then wanked him until he came yet again.

Once more she noted the details capped the jar and updated the chart. For a few moments, it looked as though he might not relent, but slowly his cock subsided. Debbie calmly cleaned him, picked up and out on her tunic, and unlocked the door the take out the sample bottles. Before she left, she picked up the iPad, tapped on the page and handed it back to Jack. On the page was the profile of 'Nurse EE' who bore a very strong resemblance to the fabulous young woman in front of him. She winked at him turned and left room where she was replaced by another of the nursing team. She whispered instructions, they giggled and away she went.

"I'm Laura" the young brunette introduced herself. "I'm afraid I'll need to observe your penis Mr Spencer, Dr's orders". Jack felt his cock twitch in response..."oh boy" he gasped.
