Today is Labor Day, which is why I asked Nancy if this could be the day of the appointment. Then I could use the lab and keep the rest of the doctors and nurses at my private practice in the dark about what I was up to because no one else would be there, not even the janitors.
I got there early and was surprised when Nancy and her son were there almost as soon as I was, "You're early." I said as I let them in the door and then locked it behind them, "It is Labor Day you know." I explained, when they saw me locking the door, "This is a special case and I don't want anyone coming here thinking we're open. It should be obvious but people can be really dumb sometimes and try to come in anyway."
I led them back into the examination room, Nancy took out a cooler filled with her son's samples. I took them out and started examining the semen under a microscope in chronological order by the date on the side of each cup. "Any problems with collecting the samples?" I asked Rob.
I was surprised when Nancy was the one who said, "No problems at all, we made sure to collect one per day like you instructed."
"Good, good," I said as I inserted the first slide into the microscope after preparing each slide. What I saw simply astounded me, "What the hell?"
"Is everything all right?" Nancy asked, sounding like the concerned mother she was. Too bad she was also the slut who broke up my marriage or I might have considered this a good quality she had. As it stood, I just saw it as a point I could use to manipulate her.
"Um, it's too soon to know, but I'll go through each of these and let you know," I put the next slide into the device. After I checked them all I took some notes and turned to them. "This is something interesting, it appears that Rob's semen production is only increasing, but not only that, his semen's viscosity, his testosterone, and his sexual pheromone production all seem to be on overdrive."
Nancy seemed confused, "you can tell all that just by looking at his, umm, sperm?" I was impressed with her, she only hesitated slightly before saying sperm and she didn't even blush. I suppose talking to her son about it every day has loosened her up some.
"I can't just see that, no, but I can deduce as much," I explained with all honesty. "It seems his testicles are on overdrive when it comes to producing semen. I'll have to run some tests to confirm what I mean, but I think at the very least we should get another sample right away."
Nancy nodded but didn't say anything. I glanced at her and saw that she was now staring directly at her son's crotch, a humongous bulge being there. She was waiting with anticipation, no need to have her wait any longer, "Take your clothes off Rob." I told him.
Nancy
I expected this moment when Xania would be telling my son to undress. In fact, I'd been thinking about it since I woke up that morning. Xania had jerked my son off right in front of me last time, ending with Rob cumming all over my clothes and body as I came in my panties without even touching myself. Well, that's been happening a lot lately, actually, spontaneous orgasms, I mean. I was still deeply in denial about everything at that time, especially my growing feelings for my son. But had I been more self-aware of my own sexuality and not just suppressing every sexual thought, or at least failing to suppress them, I might have realized that I had been so sexually repressed for so long that it was now coming out of me, not to mention
cumming
out of me, in weird ways.
As Rob got undressed, I simply stared at him the whole time. I was feeling as if I couldn't take my eyes off of him, actually. He was 18, and a bit scrawny, but as he disrobed all I could think was how manly he looked. My pussy was already very wet by the time he took his pants off and was positively dripping when his cock came into view. I was both unsurprised and very impressed to see that he was rock hard already. His huge cock, a monolith to manliness, and my cunt was calling out to me for attention and it was taking all my strength not to put my hand down my pants and start masturbating right then and there.
But again, I was in denial of the fact that I was having these very direct sexual feelings for my son. I saw him as a man, I saw him as a sexual being, I thought about his cock entering my throbbing pussy and fucking me basically all the time, but it was like I still knew Rob was my son, and seeing him in this way was just me thinking about how a girl his age might see him. Not how a very horny mother from years of self-denial in her sexuality was looking at her own, incredibly hung, son.
"Hmm," Xania said as she touched my son's penis without gloves on, she had done this last time too, using her bare hands so I didn't question it. She seemed concerned as she pushed his cock this way and that to see it from every conceivable angle. "It's extremely chafed," she said, "Have you been masturbating more than once per day?" She asked Rob.
Rob blinked nervously, "Uh, no, except..." He trailed off.
"Except what?" Xania asked. "It's important I know as this might be a result of your continuing condition or not."
Rob sighed, "I jerked off a lot yesterday..." He admitted as his face flushed red.
I felt my face going as hot as Rob's was, at least, as I remembered that yesterday was also the day I got naked in front of my son and not only let him cum all over my face and body but swallowed a great deal of it right in front of him. I was, basically, rationalizing this as not getting enough sleep yesterday, but Rob admitting that he had to jerk off even more after I did that, well, it turned me on. My sex drive was pushing all my doubts out of the way again at that moment, just as it had done yesterday when I did what I did for my son.
"Why? Did something happen yesterday?" Xania asked, glancing between Rob and me. I wonder if she knew somehow as she looked my way, but neither Rob nor I said anything.
"Well," Xania said, moving on after our awkward silence, "This is an interesting development, I would say that Rob shouldn't be so rough, especially if we're going to be doubling how many semen samples we get per day." She began slowly jerking Rob's huge cock with both of her soft hands, and this distracted me for a moment as I watched in horny fascination as Xania's words caught up to my brain.
"Wait, what?!" I said, shocked. I had come in there hoping that we could stop Rob's semen collection after that, but now she's telling me we're going to have to start doing it more!!?? I felt myself getting weak in the knees at the thought so it was a good thing I was already sitting down.
"Yes, and try to do them about 12 hours apart if you can for more accurate measurements. But don't worry if you're off by a couple of hours." She explained, she was still stroking my son's cock but very slowly, "also, do you see at the speed I'm stimulating your son? I think that this is the appropriate speed to do so. I think he should be carefully observed during these sessions to make sure he maintains this 'slow stroking' speed."
My mind was doing flips, "what do you mean by that?"
"I mean," Xania explained, "I want you to watch him at every session to make sure he doesn't chafe, as that can cause long-term problems really quickly if not properly treated. He can take preventative measures by slowly stroking himself in this manner." She jerked all the way to the top of his cock and smeared a bunch of the pre-cum coming out of my son's cockhead into her hands and down his shaft, making it glisten obscenely in the clear fluid. She was on her knees in front of him and her face was only inches away.
I was too horny. My body was hot. My pussy felt like it was about to explode, and maybe it was in yet another random orgasm without me even touching myself. This seemed unreal. I had been spending most of this past week trying
not
to think about, let alone
see
, my son's huge cock, especially while it was spewing cum all over the place. But now I was going to have to watch as he did it and
twice
per day instead of just once. These thoughts were turning me on more than anything else, but I knew, in the back of my brain somewhere, that I should be very, very worried about this.
My thoughts were interrupted as my son started to cum all over Xania's face.
Rob
What the flying fuck!?
Was all I could think as Xania, the incredibly hot blonde doctor on her knees in front of me while she jerked me off, explained that Mom, my super amazingly hot mother who even when she dressed as conservatively when she did I could still see her beautiful body underneath, would be watching me from then on as I jerked off. I mean, I didn't really think that would be necessary but I also started thinking about when she helped out yesterday. Just how beautiful her naked body is. How hot it was when she was swallowing my cum, how sexy she looked with my jizz clinging to my mom's body.
I came. I didn't announce it as I hardly noticed I was about to until waves of intense pleasure came out of my balls, up my cock, and moved throughout my body. It was even more intense than any orgasm I've had before but I was able to keep my eyes open for once by straining myself. But not to watch Xania as I covered her in cum but instead, I kept my eyes on Mom. Her beautiful face was dripping with lust and she bit her hot lips and started shaking but didn't make a sound. Still, I could tell that she was orgasming as she watched me covering the doctor's face with my cum.
Xania stood up, her doctor's uniform completely ruined and her face was covered along with thick white streaks clinging to get blonde hair. "One more thing," she said, "there's a collection unit in the front of the building you can drop the semen samples off at, once per day." She said as she ushered us out of the office. I thought she might have been a little embarrassed by being so covered in my cum...
Xania
Well, that was a little embarrassing. I hadn't planned on taking a facial like that and was kinda hoping to cover Nancy again with her son's semen. However, that didn't happen as I think my words had maybe excited Rob a bit too much. But I had been so focused on Nancy and her growing lust for her son that I never considered her son was having an increased lust for his mother as well.
I took off my clothes, they were basically ruined anyway and started masturbating as I ate the rest of Rob's cum off my body. All I could think now was how I was going to get them to fuck. If I could get Nancy to fuck her son, that would be the perfect revenge.
Of course, the 'slow stroking' idea was total bullshit. Just a reason to get Nancy to watch her son masturbate. But as I swallowed Rob's semen and only got hornier as I did so I knew that something really was medically wrong with him. I'm normally not the type to swallow a man's cum but this was addictive. It tasted great, both salty and sweet, and was making me feel more and more aroused as I ate it. Like it was affecting my hormones in some way and putting me through the roof sexually.
I had to masturbate myself through three orgasms in a row, each one stronger than the last before I finally came down and could think clearly.
I wondered if Rob's condition was a long-term one once my thinking was clear enough for me to do so. I also wondered if it was very serious but decided probably not and it was okay for me to have my fun. This was just about revenge after all.
