Doctor Appointment (Physical)

My mom took me to the doctors for a physical when I was either 14 or 15. There was a part of me that was excited, yet another part of me that was nervous.. I was excited because I knew I would be partially undressing and possibly get to show off a bit. I was nervous because I just didn't want to get hard in front of my mom and doctor. So the day of my appointment came. The nurse got my height and weight, before leaving the exam room asked me to remove everything except my underwear for the doctor. The nurse left the room, my mom asked me if I wanted her to step out. I answered her, "Na you can stay, you see me in my boxers everyday." Its normal for me to lounge around in my boxers at home, so I figured what's the difference. I stripped down to my boxers and put my shoes and cloths on the chair next to the one my mother is sitting in. I hopped up on the exam table and sat waiting for the doctor. While sitting there on the edge of the exam table, I had noticed the boxers I had on did not have a button on the fly opening. It excited me to think perhaps my mother may get a glimpse of my dick through the opening during the exam. A few moments later the door opened and in came the doctor. He said hello to me, then to my mother, then made himself comfortable on his rolling stool. First he spent a few minutes asking questions regarding my diet and physical activity. Once he was done talking to me, i kind of zoned out and wasn't really paying attention while he spoke to my mother. I sat staring down at my bare feet dangling just above the floor. Then my eyes returned to the opening of my boxers. It was slightly open, enough to see flesh on the inside, but not enough to see anything clearly. I sat staring at the visible sliver of flesh peering back at me through the opening, my mind became overwhelmed with possible scenarios. That's when I felt the doctors cold stethoscope on my back, he moved it around a few times, then onto my chest asking me to take deep breaths. I managed, but found it difficult, I felt like I was taking short shallow breaths. I could feel that I was getting excited, like an energy running throughout my whole body, and a surge of warmth flow down through my penis. I was feeling so turned on but still nervous of what would happen. Just then the doctor asked me to stand for him. Sliding my butt off the exam table, feeling the cool floor under my bare feet, though I felt like I was trembling I stood nice and tall for him. Without warning he pulls the front of my boxers down, revealing my smooth dick an balls for the ol olrn your head and cough. I glanced at my mother to see if she was looking. She saw everything, watching as the doctor felt my hairless balls then moving on to the hernia exam. I couldn't believe this was happening. Originally I thought she may get an accidental glimpse but not this. I could feel the blood surging into my penis, as it started to swell to a semi erection. The doctor, finishing my exam puts my boxers back into place. My semi hard on is now starting to tent my boxers. Spreading the opening enough to see the head of my penis beginning to push through. When he was done, he told me I could have a seat back on the exam table again. So again I hopped back up on he table, letting my feet dangle. He began going over a few things with my mother after my exam, again i was so excited I couldn't focus on them. As I sat there on the table with my hands by my sides, I look back down at my semi and see it looking out at me, I could feel more and more blood flowing into it. As exciting as all of this was for me, I definitely didn't want to have a full on erection. I tried to make it go away by just focusing on the doctor and my mothers conversation. As I looked at the two of them, trying to look as of I was really paying attention, and not worried about the growing erection in my boxers. I tried hard not to move or even think about adjusting myself, that would just bring attention to it. I continued to try and focus on them. The doctor, while still speaking to my mother, took a urine sample cup from the cabinet. Just before getting up to end our appointment, he handed me the urine cup. "Don't be embarrassed," the doctor said. "its natural, it happens all the time. You can finish in that, just throw it away before you come out." I felt clueless, how could he possibly know what I'm going through in my head? My mother smiled at me then continued talking to the doctor. I looked down, and there stood all 5 inches of my rock solid dick standing up through the opening in my boxers. Oh my god I couldn't believe it! My entire dick was out and they were both just looking right at it like nothing had happened. This sent me over the edge, my heart was pounding. Now the battle in my head was what to do.. I quickly ruled out trying to cover it. I didn't know whether to take the chance of stroking it out now or waiting for them to leave. I did neither. Instead I just took a hold of it with one hand, looking like I was covering it, but really I just wanted to get it in my hand. Now the doctor was standing, he thanked me for coming in and was saying good bye to my mother. During the good byes, I started to slowly stroke my throbbing dick, I wanted to cum bad and was so close already. Once the doctor left the room, my mother opened the cup and sat it, and the lid on the table next too me, as I very slowly stroked, up and down. It was all so erotic I was already so close to cumming. As my mother was grabbing her coat and purse, I stood up and took the cup in my free hand. I felt like the cum was moving up my dick in slow motion, it was heaven. She says, "I will meet you in the waiting room when your done." "Be right out." Is all I was able to answer in one dry shaky shallow breath. Before the door was even closed I begin to fire the first of several thick powerful ropes of cum into the cup. Still continuing to slowly stroke, one shot after another, one rope even over shot the cup landing on the floor. I didn't care, my entire body was trembling, with each cum shot I let out a moan, audible but not loud enough for others to hear. After several thick shots they started dying off till there was just a slow dribble of cumming out into the cup from my penis. I sat back against the table, still holding the cup under my dick. At this point, that was the most intense orgasm I had ever experienced. While taking a second to calm down from such a powerful orgasmic high, I couldn't help think how I was going to face my mother. She knows I masturbate and always told me its natural and I should never be ashamed of it. Never had I though she would so causally see my full boner just sticking out like that, and right at the brink of orgasm not to mention.. I grabbed a towel from the dispenser and wiped off my dick, and the floor, then got dressed. I put the lid on he cup, and admired the sizable load I'd squirted into it before throwing it, and the paper towel away. I opened the door and made my way down the hall to the waiting room. On the drive home I didn't say much, I guess my mother had assumed it was because of my mid exam boner.. She told me there was nothing to be embarrassed of, and joked saying she was happy to see everything on her boy worked properly. I'm lucky to have such a great and understanding mother. But I did keep the fact that at the time, I could feel a small amount of cum running down my leg, to myself.
