It's All for Science

This is a story with a medical flavor, but is actually a mix of erotic couplings and fetish. No character, real or imagined, is under the age of 18.

In "Another Visit to Nurse Rachel" we saw how Rachel treated Dave's recurring erection issue that the two of them jokingly referred to as a problem. In a later story "Curing Tummy Troubles" we got introduced to Ellie, a nurse who works with Rachel, but who seems to have a bit of a latent kinky side. Now we find Dave has to make a return trip to Seattle on business and has decided to stop by to see Rachel, who incidentally is like his family and they call one another 'cousin.'

Rachel was having a quiet Monday evening only half paying attention to a series of cooking shows on the Food Channel when her phone rang. The voice on the other end said, "Hey Cuz, are you up for a visit tomorrow? I need to be back in Seattle and leaving here in the morning."

It was Dave, a great guy that she had more or less grown up with, felt like family, but they really weren't related, not even distantly. Moreover, she and Dave had engaged in some kinky sexual play whenever he got into town, so the prospect of some unusual entertainment for a day or two was usually welcome.

"Sure, sounds like fun. Besides you never can be sure what I might have in mind to spring on you as a surprise."

"Great! Keep me in suspense. I can hardly wait. See you tomorrow." And then she heard a click as Dave hung up.

"Now what can I do that's going to catch Dave totally unaware?" Rachel thought to herself. Her mind was now going to have to work overtime. She turned off the television and went to her bedroom, looked around, and then went into the bathroom. Opening the bathroom cupboard she looked over her impressive array of sex toys, but still couldn't get the inspiration she needed. She changed into an old nightshirt and went to bed, but still the idea of something different occupied her mind.

The next morning those thoughts came back before Rachel even got out of bed. "I've just got to come up with something," she said to herself, "moreover it has to be something that is totally outrageous." The thought was put out of her mind as she showered and got dressed for work. As a registered nurse-practitioner for a large OB/GYN practice deciding what to wear to work was never a question: it was Kelly green scrubs every day.

Tuesday morning was like every other as the waiting room was a continuous flow of women getting various kinds of exams and as well as those coming for various prenatal checkups. Rachel was normally tasked to doing the latter as was her colleague, Ellie. This particular morning when Rachel went to the break area for a cup of coffee between appointments, Ellie was already there.

"Hi, Rach," she said.

"Oh, hi, Ellie. How are things going?"

"It's another steady stream of pregnant women. Sometimes I have to conclude that a lot of people have to be getting laid. It just isn't me, which makes me sort of horny just thinking about it. Not only that but while my sex toys are fun they aren't quite the same thing as a guy."

"I hear you."

Then Rachel had an idea, "I have my cousin, well he's really not my cousin but I've known him for a long time, coming to town tonight and he always seems to be horny and looking for some kinky things to do."

"Kinky? What do you mean by kinky? No bondage, SM or anything like that."

"No, nothing like that. The last time he was in town I dressed up in an old fashioned nurses uniform and treated him for an erection problem."

"Erection problem? You mean you got laid?"

"Well, yeah. I'm just wondering how he might respond if he had two hot and horny women for a very steamy evening?" said Rachel who couldn't help but snicker at what she had just said. "You know, naughty."

"If there is the potential that it could end my current dry spell, sure, why not? Does he have any idea?"

"No, none."

"But maybe a couple of questions first. Is he married? Is he a looker?"

"No and yes."

"So why isn't he married and have kids already?"

"Well, why don't you and I?"

"Touché. I chalk mine up to probably being too picky, or at least it used to be that way. Anymore it's probably a case of me coming on too strong. I can be a bit high amperage."

"Yeah, I hear you. Sometimes that describes me, too."

"Next question is what do you think I should wear?" asked Ellie.

"Something provocative comes to mind. Showing off your girls wouldn't hurt for starters, right?" said Rachel with a naughty giggle.

"Those do have the ability to get a guy's attention," Ellie said with an equally naughty smirk. "Maybe a lacy pushup bra under a tank top for starters."

"Now you're thinking. Sorry I can't continue this conversation further, but I have to get on to my next patient. I can hardly wait, she's in her third trimester and at every visit for the entire pregnancy has had something to whine about. She should be really something else when she goes into labor."

"If she's whining, I hope this is her first pregnancy because otherwise I would have to start and wonder how smart she is."

"It's her first, but so long as you mention it, you don't need to be that smart to get knocked up. Just lie back, spread your legs and enjoy the ride. Still, I cant wait to hear what she has for today's complaints."

"Yeah, one of those. I had one earlier. Poor woman was very constipated and I had to explain how she had to go about giving herself an enema. I told her that she should get her husband to help but here she sat six months pregnant and proceeded to tell me that she could never do that because an enema would be too intimate. Go figure."

"I'll see you later. Come by at 7:00 we can start with a drink or two, but now that I'm thinking about it we should cover all bases so bring some sexy or maybe I should say slutty sleepwear and also a set of scrubs."

"Slutty sleepwear?! I think I already like where this might be heading. Thanks, and I'll see you tonight." At that, both nurses left the break area and headed down the hall to the exam rooms holding their next appointments.

Later that day Rachel headed home to her condo, changed into running shorts and a tee shirt, and decided that a pitcher of mojitos would be in order. She had no sooner finished making the drinks when a knock came at the door. It was Ellie. Rachel took one look at her and had to conclude that she had indeed mastered the seductive look because she was dressed in patterned leggings and a sleeveless tee under which she was braless. Clearly, Ellie was doing justice to that tee shirt as her nipples readily poked out.

After being invited in, Ellie dropped her bag by the door and the two headed to the kitchen where Rachel was insistent that they try the mojitos. After only a sip or two Rachel suggested that they change into scrubs lest Dave arrive before they were ready.

No sooner had they changed and returned to the kitchen to continue imbibing on their drinks when there came another knock at the door.

"That has to be Dave," Rachel said heading to let him in.

"Hi! It's been too long," he said giving her a warm embrace and a passionate kiss, tongue and all.

"Yes, it has," replied Rachel recovering from the intimate embrace. "I hope you don't mind, but I invited another nurse over this evening and have explained in only minimal detail the problem that you have been having. Dave, this is Ellie. Ellie, Dave is the guy who I've been telling you about who has a sort of odd personal problem."

Dave took one look at Ellie and couldn't take his eyes off of her spectacular chest that was hardly hidden by the scrubs even if the tank top did her tits far more justice. All he could conjure up was "A pleasure to meet you."

"Want to have a mojito? I just made a batch."

"Sure, why not. We do need to get caught up. By the way, what is Ellie's specialty?"

"Ellie is a coworker and a nurse practitioner. As you know our OB/GYN practice covers the full spectrum of issues. While we don't treat males, erectile disfunction is a problem but what we see is the opposite of what you are experiencing, namely guys who can't get it up."

"Dave," began Ellie, "Maybe it would be a good idea if we started with a cursory exam if you don't mind. To keep everyone relaxed let's take the mojitos with us." At that the three went back to the master bedroom.

"Whatever you say," said Dave.

"Great attitude," said Rachel, "Now you can start by stripping off everything below your waist and then lying face down on the bed. We'll start with your vitals." At that Rachel retrieved two pairs of latex gloves, a rectal thermometer and tube of lube from the bathroom.

"You're not going to . . . ," began Dave just as Rachel inserted the thermometer.

"Yeah, I am. This is an important part of the examination. Now it won't take long so show us what a big boy you are." Two minutes later Ellie removed the thermometer and had Dave roll over onto his back. It was interesting that he was not definitely not yet erect so Rachel and Ellie continued.

"Now we need you to stand on the floor but bend over with your hands on the bed," ordered Ellie as she coated her gloved index finger with lubricant. Dave complied and moments later Ellie had inserted her lubed finger into Dave's anus as far as it would go. She was in search of his prostate and soon found the firm little organ. A little massage got Dave erect, which both nurses noticed.

"Very good, Dave. Your prostate is reacting normally. Now if you would explain to us about your frequent erection problem."

"It's not really a problem, but Rachel thought it was because I would get erect whenever she would give me an enema."

"There's nothing strange about that. Nothing at all. Just to make certain, however, there is another test that we'll perform. I'll be back in a moment." With that Ellie disappeared into the bathroom and not even two minutes later emerged had changed and was now wearing a very sheer short black negligee that revealed her ample tits with their nicely erect nipples. It was so short that it only extended to the level of her hip bones, but more importantly she wasn't wearing any panties hence her smooth pussy was plainly visible.

Dave took one look at Ellie and immediately became very erect.

"Perfect!" exclaimed Ellie. "Rachel, there is nothing wrong with him that I can find." At that she went over to the edge of the bed, sat down and took Dave's organ into her hands.

"It is so warm," she noted. "It has to be engorged with blood, but I suspect that he's also carrying a delicious load of cum, too."

Rachel, who had been quiet so far then uttered, "By all accounts he has always been very good in that regard. I just don't know why he walks around so erect."

"There is a test or two that we can perform," replied Ellie as she kissed the tip of Dave's organ and darted at it with her tongue then running circles around its opening. A drop of precum formed and she licked it off.

"The precum tastes plain yummy so we should make a note of that," she said and then took the whole organ into her mouth and began sucking. Instinctively Dave moved it in an out, but as he did so Ellie sucked all the harder.

"Ugh! Look out!" Dave warned.

"It's OK. This is a medical test so go ahead and cum," advised Ellie. Rachel who was watching all of this with great interest was getting hornier by the minute and soon had her hand down the front of her scrubs and into her bikinis where she was playing with her clit.

Rachel more or less guessed what was going to happen next and disappeared into the bathroom just as Dave ejaculated a load of cum into Ellie's mouth. Ellie was able to swallow most of it but could not help having some run down her chin. In doing so she took enough time to savor its flavor.

"Spectacular, Dave! Now I hope that your testes have produced enough of that precious juice that you have something left for when you fuck me." At that, Ellie got on the bed, laid on her back, and spread her legs. With an already stiff member Dave wasted no time entering her but rather than immediately pumping away took time to savor her wonderful 38D tits first burrowing his face in her ample cleavage and then aggressively suckling each of them. Ellie responded by moving her hips up and down and soon the two were engaged in some serious humping.

As this was happening Rachel, unbeknownst to both Ellie and Dave emerged from the bathroom wearing a strap-on and carrying a tube of Surgilube. She liberally applied some to the strap-on and then got on the bed where she proceeded to enter Dave's anus. It caught him by surprise but when she inserted it further it must have hit his prostate because the result was that he produced another massive load of cum this time being injected into Ellie's vagina. The timing could not have been better because that was the exact moment that Ellie reached her orgasm.

After that performance both Dave and Ellie were exhausted. When he withdrew from her it was like removing a cork from an inverted bottle as his cum didn't just drip out but literally flowed from her vagina. "Now that was an unreal creampie!" exclaimed Ellie with a naughty giggle. "I think medically we have ascertained yet again that there is nothing wrong with your manhood and by my professional assessment that it functions just fine. Besides, never in my life have I ever taken a load that large. Rachel, I think that after all of these tests that we need to conclude that there is absolutely nothing wrong."

"I don't know what to say," said Rachel, "Because he did have a problem the last two times he was here."

"Dave, I know that this is a real test of your manhood, but for the sake of medical science I think that what we need to do next is for you to fuck Rachel. Just remember, that his is for science and while it is possible that you might enjoy it, that is not the objective. Rachel, are you OK with that?"

"So long as it is for science," insisted Rachel doing everything she could to hold back a giggle. "I also think that a little variation might be useful so, Dave, why don't you lie down on the bed and I'll straddle you in the cowgirl position."

Deciding to play along with Ellie and Rachel, Dave said, "Sure, anything for science." At that he laid on his back on the bed. Not needing a second invitation, Rachel climbed on the bed, straddled Dave and lowered her naturally lubed pussy down on his manhood. After watching all of what had occurred between Dave and Ellie, Rachel was hornier than she recalled having been in a good long time. Dave felt great and she moved her hips to allow her vagina to enjoy the length of his organ.

Then, just as she though she was about to lose her mind with the strong orgasm that ensued, Dave began to cum. While she had been uncertain with the amount that he might have left, she wasn't disappointed to feel the spasms that then deposited more of his seed deep inside of her. After what seemed like a prolonged ejaculation, Dave was now spent, but then again so were Rachel and Ellie.

All three concluded that Dave didn't have any problems that they could detect with their extensive research, but just to be on the safe side, recommended that Dave find time for further observation during his future trips to Seattle.

"That sounds like a good plan," said Dave. "After all it is for science, isn't it?"

"Absolutely!" chorused the two girls.
