Dr. Mom examines her son and gets a surprise

Still a work in process, but:

You will never believe what happened to me yesterday. My 18 year old son ejaculated all over me. Really! How could I ever let such a thing happen? I am a medical doctor, currently practicing as a plastic surgeon. I am also a recently divorced single mother. Yesterday, my son insisted he was indisposed and incapable of attending school due to some severe groin pain. Being a devoted mother, in addition to a medical professional, I decided to evaluate his condition. Now, I'm no urologist but I do know my way around the anatomy and this seemed like a suitable reason for examination.

At first he protested. I suppose it is natural for a teenager to be uncomfortable with his mother examining his privates, but eventually I was allowed to directly inspect his testicles. I instructed him to drop his pants and underwear while I sat directly in front of him. I had a good view of his penis, which was partially erect before I began palpating his testicles. I initially noticed some signs of tightness and inflammation around his scrotum, as well as swelling around the base of his penis. I thought that a bit of gentle pressure would help to relieve the pain and swelling. Not my best idea.

After a very short while my teenage son was fully erect. I tried to spare him any embarrassment and pretended I didn't notice. My gaze was concentrated on his testicles. I asked him questions like how things felt, was the pain going away, am I using too much pressure on your testicles, etc. I got a few basic replies from him, though he could barely speak in his state of embarrassment. I allowed myself a quick glance at his penis, which had grown rather large. I bet some lucky girl would enjoy that some day. Was he already sexually active? For some reason my mind drifted to this dry spell I've suffered since my divorce. The sight of my son's aroused penis reminded me how much I would enjoy some sexual activity right now. Looking up and down his member, I noticed some precum gathering in his urethra and beginning to drip down over the glans. His father used to do the same thing when he was aroused.

I hadn't noticed that my son had started squirming. I thought I should stop, having already completed my examination. There was nothing obviously wrong. He just needed some warm packs to relieve the tightness and inflammation. As I was finishing up his penis suddenly started pulsing! I could feel his scrotum tighten and his stiffened shaft pumping. I let go and looked up. He began to ejaculate copious amounts of semen, so I instinctively gasped and moved back. Again,not my best idea, as I placed myself directly in his line of fire! I stared directly at my own son's penis as solid ropes of semen pumped out and onto my face, my hair, into my gasping mouth, and on my blouse. I felt the semen dripping off my chin and down between my breasts as I watched a thread of sperm dangle from my son's penis.

I was nearly in a state of shock. Just moments after my teenage son finished ejaculating all over me, I retreated to my room to assess the situation. I supposed I had brought this on myself. I insisted on examining him. After some consideration, I realized I had wanted to see an erect penis again. It had been a long time since my ex-husband and I had sex. Many unsuccessful trips on the dating scene left me resorting to my vibrator for the last year. I looked down and saw the white semen all over my blouse. I could feel it sticking on my neck. I looked in the mirror: semen was in my hair and my eye brows, on my nose, and dripping from my chin. What a sticky mess! I needed a shower. I wiped some of off my son's ejaculate from my face and started to disrobe. I readied the shower. As I pulled off my blouse, my eyes followed the long trails of semen running across the fabric. I fought an urge to touch one of the stains with my fingers. I was definitely impressed by this display of my young son's sexual ability. Very impressive.

I stepped out of my skirt and panties. Looking down at my mons pubis, I pictured having my son's semen tangled in my black pubic hair. I moaned slightly to myself. I got into the shower and started washing the sperm from my face and hair. The hot water calmed me and allowed me time to reflect on what had happened. I was still amazed by how quickly my son went from a half-erect penis to shooting his semen all over me. I wondered if he'd ever been inside a woman? Hopefully he would hold out a bit longer. I lathered my stomach and began washing my vagina. With my eyes closed and my head under the falling water, I could not notice my bathroom door open, nor did I see my son standing there, watching me wash his DNA off of my skin…
