I looked down at myself to see that my erection still hadn’t gone down. And even though I just had a massive ejaculation, I didn’t feel satisfied. I wanted to rub one out right now – or better yet, have one of them do it for me.

“I guess the little guy still hasn’t had enough,” I said with a laugh. I looked up at Beth and Ashley and smiled at them. There was now an awkward pause in which Beth and Ashley looked at each other and smiled.

“Well, I can’t let you leave in that condition,” said Beth. “Lay back, Jim. But you can never tell anyone about this, understand?”

I started to lay back on the table as Beth retrieved the tube of lubricant.

“No, let me take care of him, Beth,” Ashley said. “I really want to do this.”

Without a word, Beth handed Ashley the tube of lubricant.

“I won’t be needing that,” Ashley said with a wide grin on her face. She moved to the right side of the exam table. “Just relax, Jim, you deserve this after all we put you through.”

As she spoke, she took ahold of my erect cock with both of her hands and started to gently caress it, moving her hands slowly up and down the entire length of my shaft. Her right hand now moved down to my balls and began to hold, caress and gently fondle them. Next she bent down over me, moistened her lips and began to gently kiss the head of my cock. I now felt her tongue moving up and down my shaft, slowly licking the entire length of my member. Her hand now tightly gripped the base of my cock as she opened her mouth wide to accept my manhood. She started by taking in just my head, tightening her lips around it as I entered her. Then she slowly accepted more of me, taking my cock deeper and deeper into her mouth. I looked to my left to see that Beth was just a few feet away and was intently watching as Ashley gave me head. Ashley now began to move more quickly, riding up and down on my cock with her mouth. She wasn’t taking in all of me, but it was enough to know that she had done this a time or two before and was good at it. She tightened her grip on my balls, and I felt her lips tighten even more around me as she went up and down. It was more than I could take. My back arched, my muscles tightened and I came again. But since I had just been milked dry, this time it was a completely dry orgasm. But it was, nonetheless, very fulfilling. It was what my body had been craving during all of the tests – human contact. Sensing that I was finished, Ashley now withdrew.

“I hope you enjoyed that, Jim,” she said as she licked her lips, “because I sure did.” As she spoke, she retrieved a wet wipe and used it to slowly clean the entire length of my cock. “Lift up your knees,” she ordered. As I lifted them up, she used another wipe to clean the excess lubricant from my ass. “You got a lot of lubricant up there, so you might feel some dripping for a while.”

“Thank you Ashley,” I said to her with a smile. As I did, she bent down and kissed me right on my lips. “Maybe we can see each other again sometime,” she whispered to me. “Mandy doesn’t have to know and neither does Beth.”

“That’s it for the study, Jim,” said Beth. She walked over and retrieved my jockstrap that had been hanging next to the door. “You can go ahead and put this back on and then I’ll escort you to the exit.”

I stood up and quickly pulled the jockstrap back on. My cock still hadn’t gone back to a fully flaccid state, but at least it wasn’t rock hard anymore.

“Ready?” Beth asked. I nodded yes. Beth unlocked the door and opened it. As I followed her out the door and back into the gym, I turned to see Ashley silently waving goodbye to me. I waved back and smiled, thinking of what other things Ashley and I might do in the near future.

Beth and I silently walked back to the table at the entrance to the locker room. The two girls that checked me in earlier were still there. There was a line of three guys standing in front of the table, waiting to be checked in by them to begin their physicals. They all seemed very young and were probably freshmen like me. They were all wearing just a jockstrap and all had a deer-in-the-headlights look on their faces, as if they weren’t expecting to be stripped and humiliated like this. I hoped for their sake that they only had to endure the actual physical exam and not the extra studies.

“All set?” one of the girls asked. She reached out for my hand and scanned the barcode on my wrist band one last time. “My, you look absolutely worn out, like you worked up quite a sweat. I didn’t think these exams were so strenuous.”

“Jim was in both of the optional studies,” Beth commented.

“Oh really? Both of them? I guess that explains it then,” the girl said with a wide grin on her face.

“I’ll see you soon, Jim, take care,” Beth said with a smile.

I silently waved goodbye to her as I turned and walked toward the locker room entrance. I was no longer concerned that by walking away from her, she would see my bare ass. I no longer cared that the two young girls at the table were probably looking at me. No, I was far beyond that now. Walking around in just a jockstrap seemed almost reasonable now, compared to what I had just been through. Maybe that was the point of it all, for me to feel better in my own skin and to have the confidence not to really care what anyone else thought of my body.

I walked into the locker room and immediately noticed that it was much more crowded than before. I guessed that most of the guys simply slept in and decided to get their physicals later in the day. I made my way back to my locker, passing seven or eight young guys in various stages of undress. As I passed them, they all stopped what they were doing and looked up at me. It was almost as if they were in shock to see someone that had followed the very same instructions that they still held in their hands. To them, I was a survivor – someone that went through this ordeal and lived to tell about it. By the look on their faces, most of them were still in shock to learn that in just a few moments they too would have to strip down just like I was, and pull on just a lowly jockstrap to cover their manhood.

I removed the key that was still dangling from my neck and prepared to open my locker. As I did, I noticed a young guy sitting on the bench next to me. He was roughly in the same spot where I met Mike earlier. He was just sitting on the bench and looked like he was reading and re-reading the instructions.

“I guess you really do have to do this, right?” he said to me. “I mean, it looks like you did. You have to strip off completely and then put on this jockstrap?”

“Yup, that’s right,” I answered as I peeled off my jockstrap and stood nude in front of him.

“But, what is it like in there, I mean in the gym? Are the exams done in private? There aren’t any women in there, right?” he asked. As we were talking, he started to undress. He had removed his shoes and socks and was now in the process of pulling off his jeans.

“Um, just do what the instructions say to do. You really don’t have a choice,” I replied. “You’ll catch on to how they do things pretty quickly. I think the whole point is for you to lose any hang ups that you might have about your body and to feel like you’re part of a larger team. My advice is to just relax and let it happen.”

The young man looked puzzled about what I said. But then I realized that he might have bigger issues to deal with than just the exam. I looked at his manila folder and noticed two labels on the cover: One green and one purple.

“Hey, I noticed that you’ve got some labels on your folder. Did they tell you what those are for?” I asked. As I was speaking to him, I started to get dressed, first by pulling on my white cotton boxers, then by pulling on my jeans. I now sat down on the bench and started to pull on my socks and shoes. I looked over at him and saw that he had now removed his shirt and was standing next to me in just his white briefs.

“Ah, yeah, they said something about some studies, and that I was randomly chosen for them. They said the green one means I’m in some kind of growth and development study and the purple one, that label just says HSDP on it, so I’m not sure what that one is, but I know it’s some other study. They told me it was no big deal!”

“Oh, OK,” I replied. I didn’t have the heart to tell him what was really involved in the studies. And I especially didn’t want to tell him what HSDP stood for. I figured he’d find out soon enough what that was all about. I stood up and pulled on my T-shirt. I looked over at him and saw that he had now pulled off his briefs and was standing nude in front of me. For a brief moment, I looked at his body. He was young, like me -- it probably hadn’t been long since his 18th birthday. His body was muscular and fit, but he still looked boyish, without a lot of body hair. His pubic hair seemed like it had recently been neatly trimmed, with most of the hair around his balls and cock being trimmed completely off. Without a lot of hair, it was easy to see his low-hanging balls, and the above-average length of his circumcised penis. As I looked at him, I imagined him standing spread-eagle before Beth and Ashley as they took photos of him and measured him. I imagined one of them holding his flaccid penis and carefully measuring it before moving on to his testicles. And then there was HSDP! This poor boy had no idea what he was about to endure. I imagined Beth and Ashley restraining him on the table and spreading his legs apart. And then one of them would probe his tight ass with their fingers before using the dildo on him, and ultimately the electric probe. I wondered which one of them would have the honor of getting this boy all worked up. Would it be Beth or Ashley? As he reached down to step into his jockstrap, I wondered just how big he would get. Would he be bigger than me? Would he last longer than me? And would Ashley or Beth help him get off when they finished with the study? Or was that something special that was reserved just for me?

“Well, good luck,” I said to him as I started to walk away. Carrying my lock and key and my trusty jockstrap, I made my way through the sea of bodies to the exit. The male attendant was still there, but he was busy directing a line of guys as they were entering the locker room.

“Just deposit your lock and key and your used jockstrap over there,” he said, pointing to a table on the other side of the exit.

I inserted my key into the lock and put it into the box with the other locks. I saw the large laundry bag that was filled with used jockstraps. I held my jockstrap up, preparing to throw it in with the others. The waistband felt wet with sweat. My fingers moved over the pouch and it was also wet, with either sweat or other bodily fluids, I couldn’t be quite sure. Just at that moment, I decided to keep it as a memento of my morning. I thought it might come in handy in the near future. I looked around to see that no one was looking at me, then I wadded it up and stuffed the jockstrap into the front pocket of my jeans. Then, with a smile on my face, I exited the locker room and walked back to my dorm.
