During one of my frequent trips to the doctor in my college years, I mentioned to my doctor that I had been having some trouble urinating. He couldn’t find the exact cause, so he referred me to a urologist. I had no clue what to expect. When I got to the office on a thursday afternoon, I checked in and the receptionist handed me a clipboard to fill out with my medical history. I wrote about my previous bowel problems, and had to check a lot of detailed boxes about what exactly was going on with my other bathroom habits. I handed the clipboard back to the receptionist and waited anxiously for about thirty minutes. Finally, a nurse came out and took me back into an exam room. She introduced herself as Rachel and told me I could have a seat on the table. I sat on the table as we discussed my problems urinating. Next she took my vitals and recorded them on her chart and told me the doctor would be in shortly. Not five minutes later, Rachel returned with the doctor. She introduced herself as Dr. Williams and we made small talk. This doctor had to be fresh out of medical school, and didn’t look older than 28. She talked about some possible causes of my problems but made sure I knew how common this was among men as she snapped on a pair of rubber gloves and sat on her stool. “Alright I know you’ve done this plenty of times. Go ahead and stand up and step out of your pants for me”. I stood up and took off my jeans and sat them in a nearby chair. She then motioned for me to step out farther from the table and I did so. “Just gonna slide these down real quick” she said as she swiftly dropped my tighty-whities to my knees. “Relax for me, I’m only going to touch.” She began to examine every inch of my penis, from the tip to the underside. “Spread your legs a little bit for me now, I’m going to examine your testicles”. I widened my stance and she quickly moved her hand and cupped my balls and began to gently rub and squeeze them all around. My testicles are very sensitive, and this caused not only my body but my penis to twitch. “Now I need to check your prostate. Turn around and lean over the table for me.” she said. I assumed the position as I had in the past, facing my pale white cheeks towards Rachel and Dr. Williams. “Spread your legs a bit for me hon” she said and patted my right cheek. I widened my stance again, and I could feel the back of my scrotum being exposed and I gently pressed my genitals against the cool exam table. “Just going to have a look” she said and I felt a gloved hand on each side of my ass as my cheeks were forced open. Next I heard the squirt of the KY as she quickly pushed two fingers into my awaiting ass. She began to sweep, twist and turn her fingers throughout my back passage, and I felt my cock begin to stiffen. “When was the last time you had a bowel movement?” Dr. Williams asked. I told her yesterday, and she explained that she couldn’t feel much because I was backed up. She told me she would give me an enema. My stomach dropped upon hearing this. I never expected to have an enema at the urologist! She asked if I had ever had one, and I explained that I was all too familiar with them by now. She chuckled and told Rachel to grab one. I looked and was slightly relieved to see that it was a Fleet enema that Rachel grabbed. “Go ahead and lay up on the table on your left side. You can step out of your boxers for now.” I assumed the position with my cock and balls facing the two women at the front of the room. Rachel stepped behind my and guided my top knee up towards my chest. She stroked my bottom cheeks and told me to relax as she pushed my top ass cheek up and out of the way. I felt the slim nozzle slip into me and a rush of a rather small amount of cool liquid compared to what I had previously experienced. Dr. Williams said she wanted me to hold it for about ten minutes. I thought that this would be easy, but it soon proved difficult as I felt the solution begin to stimulate my bowels. I began to twist and pant audibly. Rachel explained that turning on my stomach may help me hold it so I followed her instructions. Pressing my cock against the crinkled paper on the table caused it to instantly stiffen. I was breathing heavily when Rachel guided me up towards the bathroom, and told me there was no one else in the office. I took about two steps towards it and was shocked when I saw the receptionist looking from down the hall. She gasped and covered her mouth as my stiff cock bounced with each step. I covered my genitals and quickly ducked into the bathroom. Once I had evacuated my bowels, I returned to the exam room. I was instructed to return to my position bent over the table. Dr Williams once again slipped two lubricated fingers up my virgin hole. Again, my cock swelled against the table and I couldn’t hold back a soft grunt as she began to push on my prostate. She continued to rub my button and I slightly buckled my knees and pushed back against her finger. My cock was rock hard now, hidden away as it was pressed down against the table. Dr Williams removed her finger and I stood up. “Your prostate does feel slightly enlarged and I’d like to get a better look with the probe” Probe? I thought. “Up my butt?” I asked as I sat on the table. “Yes, unfortunately the probe does go up your bottom” she said. Wow! I thought. Every doctor I visit, it seems like there is special attention paid to my ass. “When was the last time you ejaculated?” She asked. Caught off guard, I stammered “ Well…uh…I’m…maybe a week ago?” Dr Williams explained why she asked and said she may get a semen sample to rule out other issues. I couldn’t help but picture me sitting in the bathroom I was previously in trying to jack off into a cup. Dr Williams explained the prostate probe procedure, and told me it wouldn’t hurt and that we could go ahead and take care of it today if I was free since I was already cleaned out. I agreed and she told Rachel to prepare the probe. Rachel walked to the cabinet and took out the probe. It looked almost like a dildo with a cord coming out one end. I gulped as I remembered where it was going. “Hop up and lay on your left side for me.” Dr Williams said as Rachel rolled over the table with a few items on it, including the probe. I did so, staring at the table next to me as I assumed the position with my ass facing the Dr. Rachel draped a blanket over my legs up to about my mid thigh which did help ease my discomfort. “Lubricate him” Dr Williams said. Rachel put one gloves hand on my right ass cheek and exposed my hole, then pushed her slim finger deep into my rectum. I saw Dr Williams hold the probe, which couldn’t have been more than 6 inches long but had to be almost 2 inches wide. “Now I need you to relax and bear down like you’re trying to go to the bathroom honey. You may feel a little discomfort when it first gets in.” That was an understatement. I knew “discomfort” from a doctor only meant pain. Next I felt the tip of the probe at my entrance and tried to bear down. I began to feel a stretch as it made its way in and I jumped. “Ahhh…it’s so big…” I gasped. Rachel put her hand on my hips to hold me down and took her other hand to hold my ass cheek up so that Dr Williams could continue to stretch my ass. I continued to groan as Dr Williams slowly but surely pushed the massive device up my ass. I had had things deeper in my rectum, but never something of this diameter. However, I looked down and noticed my prick standing straight up. Dr Williams soon announced it was in and that she just had to take a few pictures and we would be done. I laid there and tried to daydream while I waited. Soon Dr Williams said she was going to remove the probe, and I soon felt her slowly pull it out and heard an audible “pop” of my anus as it came out. The Dr told me I could sit up and said that her and Rachel were going to step out of the room to evaluate the ultrasound images. They left the room and I sat there and waited, my cock still at full attention and my heinie still wet with lubricant that I could feel dripping between my cheeks. My asshole still felt stretched. I debated finding the KY and jerking off but I was afraid to get caught. Eventually I grabbed the towel and decided to cover my lap. Dr Williams and Rachel returned, and explained to me what they thought the cause for my troubles was. Dr Williams said that she thought it was a bacterial prostate infection, and that she wanted to do something called milking the prostate so she could get a sample of my prostatic fluid to confirm her diagnosis. She then told me to get up on the table on my knees and to put my chest down facing the other way. I assumed the position, and began to recognize that this next portion of the exam would again involve my ass. Rachel spread my knees just a bit, and Dr Williams explained that she was going to stick her finger up my bottom to massage my prostate to release some fluid. She explained that I may feel like I need to urinate but that it was normal and that Rachel was going to catch the fluid. She also asked that I try not to orgasm in case she needed a semen sample. Try not to? I hoped I wouldn’t feel the need! Dr Williams then put one hand on my left cheek and slipped two fingers into my rectum. “Relax for me” she said and I felt her began to push on my prostate. My erection quickly returned, and Rachel guided the tip of my member into a beaker that she was holding with her other hand. Dr Williams continued to push and tease my prostate with her finger, which continued to turn me on. She told me to relax again and began to gently tease my balls with her other hand. I arched my back and pushed my ass up further for her as I let out a soft moan. I was indeed going to have to try not to orgasm. “He’s releasing some” Rachel said. I grunted as I looked down between my legs and there was a bit of milky-clear fluid leaking from my cock into the beaker. “Not much longer. Just hold on” Dr Williams said. She began to push and prod my man button faster. I began to buck my hips, almost in rhythm with her hand. I let out a grunt and Dr. Williams must’ve taken that as a cue that she needed to stop before I had an orgasm, as she said that was enough and removed her hands from my lower half. Rachel also removed my cock from the beaker and placed it to the side. Part of me hoped they needed a semen sample, and if they didn’t, I was going to consider finishing the job myself. The embarrassment and vulnerability to the two women somehow excited me more.

“Last part” Dr. Williams said. She said it wouldn’t hurt to get a semen sample (I thought that was a funny way of putting it) since I was already erect. Dr Williams said one other person would assist in obtaining the sample, and she left the room to get her. When she returned, the front desk lady was with her! I was so embarrassed as she obviously knew what was going to happen. Dr. Williams explained that Erica would be holding my hips, Rachel holding the beaker, and that she would stimulate my prostate and my organ herself. Then she told me to assume the position on my hands and knees again with my head down and my rear up high. Next, my wrists and ankles were secured to the table with velcro straps. Dr. Williams explained this was merely precautionary so I didn’t fall or roll off the table. Somehow being tied down felt wrong. Next, she told me to close my eyes and relax. I then felt something at my anus that was bigger than her finger, which caught me off guard. “Ah!” I yelped softly. “What is that?” I asked. “It’s a prostate massager than can do a better job than me. We have to be sure to stimulate release from the prostate to get a good sample.” I gave in to yet another intruder up my butt. It wasn’t quite the diameter of the prostate probe, but I could feel it curve along my back passage. “Hold still” Erica said and lightly rested her hands on my hips, keeping them up high for the Dr. “I’m going to start the massage now” Dr Williams said. I heard a click and soon felt a wave as the massager began to vibrate. Its tremors would slowly ramp up, peak, and then come down in speed till it was at rest, then repeat. “Oh my…” I said. I looked down at my cock that appeared flustered in the grasp of Dr Williams. My balls were drawn up tight and i knew i was almost ready to blow. Dr. Williams said the longer i could hold back, the better the sample would be. “Uhhhh….mmmmm….” I was trying to stifle my grunts in moans in front of these women. I had never felt this submissive, yet turned on. My entire body was twitching with each pulse.

I arched my ass up high and clenched my ass cheeks, and I felt every muscle in my body contract. My tight asshole spasmed around the toy, and with a lot of moans and grunts, I blasted endless ropes into the beaker. I had never seen my dick release so much volume. Once I was done, she removed the beaker and I collapsed there, face down, bare assed, trying to collect myself after I had just been milked like a cow. “We’ll give you a few minutes to yourself. There are tissues here on the counter.” Dr Williams said. I couldn’t even muster a response as Rachel untied the straps. Any dignity I had when I entered the office was gone. I finally sat up and wiped the remnants of my load from my cock. They returned a few minutes later with an orange tray. Dr. Williams told me she was going to give me a shot to take care of the infection in my prostate. I said okay and Rachel came over preparing the needle. Dr. Williams told me after that I would be good to go and exited the room. I asked Rachel to do my left arm instead of my right. “Oh boy, this goes in that cute little tushy of yours” she said and winked. I blushed beet red and my cock began to stiffen, albeit slowly. “Face down for me” she said and patted the table. I buried my red face into the pillow and slowly pressed my genitals into the table. I smelled the alcohol as Rachel began to swab my left ass cheek. I hated shots, and the humiliation here made it even worse. I turned my head to watch her draw up the fluid. I gulped as it looked like a lot of a thick, yellow-brown gunk. “Alright. Relax your heinie for me” she said as she patted my bottom. Next I felt the needle pierce the skin of my rear, which didn’t hurt to bad. But when she began to deposit the think goo in my cheek it burned like hell, causing me to clench my cheeks tight. It felt like it lasted forever and I was in agony. She withdrew the needle and put a bandaid on its prick. “You know it helps if you push the medicine around some” she said suggestively and began to massage a small lump left in my cheek. I felt great as she began to knead and press on my ass cheeks like a baker rolling out dough. All the attention caused my erection to come back to life. I wanted her to finish me off again but she soon stopped and told me I was all done and left my paperwork to check out. I was quite embarrassed as she watched me stand up with my engorged cock as I stuffed my member into my tight briefs. She then left the room. I noticed a sticky note by my paperwork with a number and a smiley face. Rachel was a cute girl, and although it seemed inappropriate, I thought I might take her up on the offer. I limped out to the front desk lady who I couldn’t quite look in the eyes knowing she had just witnessed my tight white ass and my convulsive orgasm. Once I left I started to think about what plans I might make with Rachel.
