Nathan was a squarely built, well-muscled 18 year-old football player from Jennings, a small southern town in northern Florida near the Georgia border. He played both tight-end and linebacker on his high school team, and was being recruited by several colleges for his defensive skills by several regional teams.

Nathan had only grown into his relatively impressive frame in the last couple of years. Prior to his growth spurt he'd been a homely, scrawny youth. He lacked the confidence and attitude of many boys his age that had less going for them. In truth, he was a rather bashful young man.

To compound his bad luck, his small high school had more than twice as many boys as girls, and he'd long since been out-competed by the more confident boys for the affection of the two or three girls who even bothered to acknowledge his existence.

On his last visit to CFS, he was coming out of a shower after a workout and one of the seniors on the team pulled him aside.

"Hey man, I think if you decide to come here you'd be the kinda guy that can make some money with a special program. It's only done at CFS, and the right guys can make big bucks and it's all legit with the NCAA. One of the Profs runs it, but you have to try out."

"Sounds too good to be true. What do I have to do?"

"Man, I can't tell you, it's some kind of super-secret that you can only know if you are accepted. But if you get in, it's like a dream. Seriously. Check it out ... it can't hurt. You can always say no if it's not your thing."

Nathan called contact number. The lady who answered said she was a nurse, and she had all kinds of medical instructions for the young man that she said he had to follow strictly if he wanted a chance to get into the very exclusive program.

The one instruction that sounded most strange to Nathan was that he was absolutely prohibited from ejaculating for two whole days before his appointment. He could have sex (he didn't let the nurse know that he was still a virgin) and he could masturbate, but he couldn't let himself ejaculate. She told him it was critical that he not tamper with his hormone balance before the tests or he would probably fail, and if he did there wouldn't be a second chance.

He was given the choice of an early morning or late afternoon appointment, before or after the clinic was open. She told him this was because they saw a lot of flu patients this time of year, and didn't want to risk him getting sick. Nathan took the morning appointment. He didn't explain this to the nurse, but never been able to go more than a full day without whacking off ... he usually masturbated two or three times a day at least, and he wanted to get whatever was going to happen done as soon as possible so he could relieve the pressure sooner.

On the morning of his appointment, Nathan was greeted at the lab by a very attractive, young Hispanic nurse who introduced herself as Angela. She was wearing green hospital scrubs and white nurse's shoes, with her dark, wavy hair pulled back in a tight bun. From what he could tell of her shape under the scrubs, she had large breasts and curvy hips.

Angela led Nathan back into an exam room. "Strip down to your socks and underwear ... you are wearing underwear, aren't you?" Nathan nodded. "Good. Strip down and put your clothes over there on the counter, shoes on the floor. I'll be back in a minute and we can get started."

He quickly stripped down to his jock strap, which was the only clean underwear remaining for this campus visit. He wished he'd had some briefs left, he didn't realize that the nurse was going to see him almost naked. Nathan was used to being naked around guys in a locker room, but not around women. The thought was starting to get him excited, and as he started to get hard, he got more excited that the nurse was going to notice his growing boner.

The nurse gave a perfunctory knock at the door and opened it before Nathan could even respond. She looked him up and down with a slight smirk on her face. "Very good. You appear to be ready. Follow me."

She stepped out of the exam room and turned down the hall, leading him briskly past several empty examination rooms until they reached a nurses station. There was no one else at the station, and she motioned for him to step up on the scale, turning his back and conspicuously naked ass framed by the thin straps of the jock to the rest of the room.

"Put your hands at your side, you're jiggling the scale." As Nurse Angela slowly adjusted the weights on the scale to get an accurate reading, Nathan heard the noise of a door opening behind him.

"Oh my, Angela, what have we here?" another woman's voice said excitedly. He turned his head to look and Angela shot him a withering glance.

"Hold still! Now I have to start over." Nathan stared straight at the wall in front of him and Nurse Angela turned her attention back to the weights, while speaking over his shoulder to the new entrant. "Dr. Murphy wanted me to test him for possible entry into the program, Jenn."

"Nice! I hope he makes it. From what I can see he'd be a great addition. He has superb ... muscle tone from this angle. Don't you agree, Barbara?"

"Very nice tone, balance and a lovely firm shape, Jenn. He'd make a great addition to the study."

Nathan had already begun to blush just from the realization that there was another woman in the room. Now his whole body turned beet red at the thought that these two women whom he couldn't see were staring at his naked ass. Even though he was deeply embarrassed, he was also beginning to be deeply aroused, and he could feel his cock start to thicken even further in his jock. He tried to think about something else, distract himself, but the sense of women's eyes on his naked rear just grew stronger, and as it did, so did his erection.

Nurse Angela looked down at her patient's growing "problem" and smiled. "Ladies, please. Can't you see you are embarrassing the poor boy? You're making it very hard ... to complete my work."

"Sorry, Angie, let Barbara and I know if you need a hand or two with your examination, okay?"

Nurse Angela looked down and saw that the bulge in Nathan's jock had grown so prominent that it started to lift the mesh fabric of the pouch. The other nurses were right, young Nathan looked to be an excellent candidate for Dr. Murphy's program. The nurse took Nathan's height measurement and had him step back off the scale.

"Nathan, I need to do a quick balance test. Lace your fingers together and put your hands behind your head. Yes, just like that." Nathan looked down to see the Nurse gazing directly at his semi-hard cock. Just the knowledge that she was looking at him—and that the expanding mesh of the material gave her a pretty good view of his long, thick member and his large, heavy balls—was enough to give him a complete hard-on in just the few seconds before she spoke again.

Nurse Angela smiled, "Close your eyes and tilt your head backward as far as you can without arching your back. There, that's good. Now without looking down or opening your eyes, turn a complete circle and face me again."

He did as he was told, hearing some whispering at first from the two ladies behind him. As he slowly spun about, being careful not to fall, and was facing directly toward them he heard a gasp and a giggle. He knew the two other ladies were starting straight at his hard-on, barely concealed in his jock strap, and while a second earlier he would have said his cock couldn't have gotten any harder, it got harder still at that moment. Even against the tight confines of the mesh he felt it start to lift away from his balls, straining toward horizontal.

As he completed the 360 he heard Angela's voice again "Keep your hands behind your head but you may straighten up and open your eyes." Nathan did as he was told and opened his eyes to see the young Hispanic nurse gazing directly at his stiff member, which would have been bouncing and throbbing except for the thin layer of elastic fabric holding it back. She spoke to him without looking up. It was as though she was talking to his dick. "See? You ended up right on target. Good job!"

"Walk down back down to the exam room and step up on the stool behind the privacy screen. I'll be there to take a few measurements to determine your suitability, so don't touch anything, including yourself, until I get there."

The young athlete tried to catch a glimpse of the other two ladies as he turned to walk down the hall, but they weren't standing anywhere he could see in a quick, furtive glance. As he walked, the combination of the motion of his strides and the pressure of his massive erection loosened the pouch of the jock, allowing his cock to stand straight out in front of him.

He closed the exam room door behind him and quickly stepped up onto the stool. He almost instinctively pushed his cock down in his jock when he remembered that Nurse Angela had said he was not to touch himself. Nathan was really enjoying the attention, so much so that he began to shake from erotic anxiety. He hoped that Nurse Angela would get to see him naked before the examination was done.

He stood quietly and waited with his boner throbbing away, pointing toward the door, ready to greet the lovely young nurse when she returned.

Nurse Angela slowly opened the door to the room and backed in, rolling a draped medical service cart behind her. Under the drape were some indistinct shapes, and on top of the draping there was a clipboard, a pen, a box of tissues and a measuring tape.

As she backed the cart around the end of the privacy screen, Nathan noted that his height, plus the height of the step stool he was standing on, resulted in his erection pointing right at shoulder height for the beautiful Latina. She almost backed right into his cock before she finished placing the cart, picked up the clipboard and turned around toward her patient.

"Hello, Nathan. Are you holding up okay?" The nurse was still talking directly to his jockstrap, only this time her chest was maybe two inches away from his dick, and he could feel her breath on his bare stomach as she spoke. She held the clipboard up and asked him to sign the release form so that she could begin the examination. He didn't even bother to read it, just scribbled his signature and indicated he was done.

"Thanks." She flipped the waiver form over the clip and wrote Nathan's name on the top of the checklist on the following page. The way she was standing and holding the clipboard put his hard-on directly in her line of sight. Nathan was so excited by the fact that this beautiful woman was looking straight at his throbbing erection that he was getting light headed.

"So, before we start on the exam, I have to ask you something. Your penis is obviously very hard. Is that because you are sexually stimulated or because you have to go to the bathroom?"

"Ummm, I don't have to go to the bathroom, ma'am." The nurse looked up at him and frowned. A shot of fear went through Nathan; he thought he may have offended her with his answer.

"Please, don't call me ma'am ... I'm not that old. You can call me Nurse, or as Nurse Angela, okay?" She smiled again, and Nathan's fear quickly eased.

"Okay, Nurse Angela."

"So, you're saying that you don't have to pee, thus your erection is the result of sexual stimulation." She was talking to Nathan's dick again.

"Yes, Nurse Angela."

"You haven't been touching your penis, have you Nathan? I told you not to."

"No, Nurse."

"So you've gotten this large an erection without any manual stimulation. That's impressive. What about this situation excites you so much, Nathan?"

The young man's throat went dry, and his mind was whirling trying to come up with an answer. "Ahh ... ummm."

"If this is uncomfortable for you to talk about, let me suggest some reasons and you just indicate whether I am right or wrong, okay?"

"Okay."

"I'm guessing that you are not reacting to the clinical surroundings. Most young men aren't excited by health care. It's probably not the way I am dressed. Scrubs aren't top fantasy items on most young men's lists."

"No, it's not that, Nurse."

"So I'm thinking that you are sexually aroused because of your exposure. You enjoy the fact that right at this moment, there's only a thin layer of fabric preventing me from seeing your erect penis. Is that right?"

"Yes, Nurse Angela."

"You realize, Nathan, that your ability to get such an obviously strong erection as yours, under these circumstances, is fairly extraordinary. Most men, even at your age, require visual or manual stimulation of some sort to get that excited." The nurse's tone was clearly complimentary.

"No, nurse, I didn't know that," Nathan responded proudly.

"Do you realize that the mesh pouch of your jockstrap is pulled so tight that I can practically see through it?"

"No, nurse, I didn't." Nathan gulped hard.

"Good boy, Nathan, because it would probably be a violation of clinic policy for you to intentionally expose yourself in order to gain sexual gratification. I wouldn't want to have to cut this examination short."

"Me either, Nurse Angela."

"Very good," the nurse said approvingly. "Now I'm going to ask you some personal questions about your sexual experiences and activity before this date, to determine your suitability for Dr. Murphy's program. Then I'll take some measurements, and we'll be done for the day, okay?" Nathan just nodded. The nurse was still positioned so that she had to look directly at Nathan's protruding cock to see the clipboard as she took notes. It was as though his dick was a microphone and she was talking into it.

"First, have you ever experienced vaginal intercourse?"

"No, nurse." Nathan believed, incorrectly, that he was the only one in his class that hadn't gotten laid and he worried that the answer would disappoint his nurse.

"That's okay; according to studies a majority of boys at your age still haven't, though most pretend they have." Nathan blushed and his dick twitched visibly in the jockstrap.

"Have you ever performed oral sex, either with a woman or a man, Nathan?"

"No, nurse."

"How about anal sex, either giving or receiving?"

"No!" Nathan's response came out a little too abrupt. The Nurse giggled.

Nathan though he could feel the nurse's warm breath on his throbbing dick as she took notes.

"How about touching? Has anyone ever touched your privates in a sexual way?"

"Yes, nurse, there was one time last summer." Nathan seemed happy to report this fact.

"Oh, good for you!" Nurse Angela started scribbling in earnest. "Can you describe that incident for me? Did you initiate the touching, and how did it occur?"

"Well, I was with my family at a vacation house that belonged to a friend of my dad. He had a big house with a pool. His daughter was home from college and I went swimming with her and a bunch of her friends ... guys and girls. We were playing Marco Polo and she was 'it' ... but she kept going after me. I was swimming backwards trying to get away and she just reached out and grabbed me right on the dick. I think she had been peeking, even though she was supposed to keep her eyes closed."

"Are you sure that she meant it in a sexual way? That could have been an accident."

"That's what I thought, too, but later that night, after the game was over, we were all just swimming around and she came right up to me underwater and before she surfaced she grabbed my dick again, this time she held it and squeezed it pretty hard. She popped up out of the water in front of me and smiled."

"Go on."

"I didn't know how to respond. She asked me 'Does your girlfriend call you Mr. Big?' and I told her I didn't have a girlfriend and she reached down inside my bathing suit and grabbed me again and started rubbing me up and down. 'So nobody will be jealous of me if I give you a hand with this, huh, Mr. Big?' I came in like three seconds of her touching me and she giggled and put one finger up to her lips as if to 'shush' me, and then swam over to her boyfriend."

"Well that definitely counts as sexual touching. Did she ever do it again?"

"No, she drove back to college with her boyfriend later that night and I haven't seen her since."

"That's too bad, she seemed to be a good judge of character." The nurse looked down at the tip of Nathan's member and wrinkled her forehead. "You've got quite a lot of pre-seminal fluid there, Nathan, let me get a tissue so you can wipe that before it drips."

Nurse Angela leaned forward to grab a tissue off the cart and as she did the young man's cock rubbed against her blouse and pressed into the side of her breast. "Oops!" she exclaimed in mock surprise, looking down at the dark smear of clear liquid on her light green scrubs. "Guess you don't need the tissue anymore."

"Sorry, Nurse Angela..."

"No, don't worry, that was my fault. At least you won't drip now." As she held the fabric of her blouse away from her body to examine the spot, Nathan could see down inside her shirt and had a nice view of her ample cleavage, if only for a moment.

"I'll just get fresh scrubs before I see the next patient. One last question, then. Have you ever been naked and exposed, either accidentally or on purpose, to a woman who reacted favorably to the incident?"

"Yes, nurse, it was on the same trip, the day before. The man we were staying with had a new wife, a lot younger than him. I guess his first wife had died of cancer or something a few years before and he married a woman he had met at his daughter's sorority. Anyway, she was really hot and just a year or two older than his daughter. Since she was closer to my age than his, she probably felt sorry for me and hung out with me to keep me from being bored around my parents and her husband. This was before her step-daughter came home the night of the pool thing, so it was just the five of us in the house." Nurse Angela noticed that Nathan's dick seemed to be throbbing more strongly as he started to tell this story, and another drop of glistening clear fluid was beginning to build at the tip.
