“No problem, Jim,” replied Ashley, “there’s just a couple more steps and you’ll be done with the basic study. Right now I need you to hop up on the exam table.”

As ordered, I walk the few steps toward the exam table, with Beth and Ashley walking along side me. I had no idea what part of my anatomy remained to be measured, or why I had to be on the exam table to measure it. But at this point, I just wanted this entire ordeal to be over. Once there I started to climb up on the table and take a seat, but Ashley suddenly stopped me.

“We actually need you in what’s called knee-chest position for this,” said Ashley. “That means you’ll be on your knees with your chest down on the table.”

“You’re kidding. What on earth are you going to measure in that position?”

“Jim, there are just two more parts of the study,” answered Beth. “We’ll record the hair growth in your perineum area and also check your prostate to see if it’s normal size. Knee-chest is what the study instructions say we have to use for examining that area.”

I was tired of arguing. I knew I would never be able to persuade them to do this a different way, or better still, skip this part altogether. I shook my head in disgust as I climbed aboard the exam table and immediately got on my knees.

“Good, now just move your knees apart, right to the edges of the table,” ordered Ashley.

I spread my knees apart, moving each one to the respective side of the exam table.

“Almost there, now just bend at the waist and rest the upper part of your chest on the table. You can rest your arms in front of you and turn your head to one side to make it more comfortable.”

I began to bend the upper half of my body down toward the table. At first I supported the weight of my body with both of my hands as I moved myself lower and lower. But then the upper part of my chest finally was all the way down and resting on the table. I turned my head to the left, resting it on the table alongside my outstretched arms. I could only imagine the view that Beth and Ashley now had of me. The upper part of my body was down on the table, but since I was still on my knees, my bare ass was up nice and high and was now the center of attention. I could feel my semi-erect cock and loose-hanging balls dangling freely between my parted legs. As an added bonus, I also felt the cool air of the room on my exposed anus, confirming that Beth and Ashley now had a perfect view of one of the most intimate parts of my anatomy.

“Good, we’ll check your hair growth first,” I heard Ashley say.

I now felt Ashley’s gloved fingers moving up and down my exposed crack, examining the hair in the area between my scrotum and my anus – the perineum.

“Jim, you said earlier that you trim your pubic hair,” said Ashley. “It looks like that doesn’t include this area, since your hair is fairly long. Is that correct?”

“I don’t ever trim that far down.”

“OK, I just wanted to make sure our records are accurate.”

Ashley’s fingers now stopped their examination. With my head turned to my left, I watched as Beth retrieved a tube of lubricant from the counter, opened it, and squeezed a generous amount onto the index and middle fingers of Ashley’s right hand. Ashley immediately worked the lubricant between her fingers until it covered the entire length of her fingers.

“Have you ever had a rectal or prostate exam, Jim?” asked Ashley.

“No,” I answered. I briefly thought about all of the times that Mandy and I used to fool around, and how she liked to slip her fingers deep into my ass as part of our foreplay, or even while we were making love. I remembered how good it felt, and how hard it made me when she did that. But I didn’t think that qualified as a prostate exam.

“Well, it won’t take long at all. It shouldn’t be painful, but you will feel the coldness of the lubricant, and some pressure and fullness. And some men say that they feel the sudden urge to ejaculate. Just try to relax.”

I now felt Ashley’s left hand on my left butt cheek. Without any further warning, I felt the coldness of her lubricated finger touching the entrance to my rectum. At first she applied just a slight amount of pressure until I opened up to accept her. Once that happened, her index finger quickly slid deep into me. I made a sound as if I was gasping for air. Not because it hurt in any way, but that I was a bit surprised at how quickly she entered me. I now felt her withdraw her finger almost completely from me, and then just as quickly reenter me, this time with two fingers. I could tell because it felt much fuller this time. She now began to press deeper into me, ultimately finding my prostate and pressing on it to gauge its size and shape. As she continued to press on it, I suddenly felt as if I was about to ejaculate – just as she said I might. I once again let out an involuntary sound, this time it was more like a primal grunt than a gasp for air. The erection that started earlier had begun to subside, but with all of this attention, I felt myself getting hard once again.

My head was still turned in Beth’s direction and I saw that she was intently watching as Ashley penetrated me with her fingers. She seemed to have a unique expression on her face. It certainly wasn’t shock or horror, and it wasn’t entirely just a smile. It seemed that she was excited by what she was watching and also embarrassed for me at the same time. Ashley pushed on my prostate a few more times before withdrawing her fingers.

“Alright, Jim,” she said, “it feels like you have a normal size, healthy prostate.” As she was talking, I felt her wipe the excess lubricant from my ass using a moist towelette.

“You can have a seat on the exam table while Beth and I finish up the paperwork for this study and get ready for the next one.”

I immediately rolled over and took a seated position on the exam table. I saw that Ashley and Beth were both removing their exam gloves. I was certainly glad that the study was finally over, but was also very apprehensive about this second study that I was now forced into. Still completely nude, I watched as Beth made a few final notes in my study paperwork with Ashley hovering beside her.
