So I guess I may as well confess something of my own...
I've had a relationship with my step-father for nearly two years now. I never actually realized how sexual our relationship was until after the first year.
Let me start by saying that we aren't related by blood in anyway. After I realized how our relationship would be viewed, I did some research on it. Our relationship also started not long after I turned 18.
To paint a picture, my step-father doctor with a small practice, fairly devout and a widower, his first wife died in childbirth, giving birth to my step-brother. My mother was unwed when she had me and is devoutly religious, moreso then my step-dad. I'm a product of homeschooling and abstinence-only sexual education.
My mom and step-dad have been married six years this year and our personal doctor for as long as I can remember. I've come to trust my step-dad, I guess we'll call him Matthew, with everything involving my health and I usually ask him about anything I'm too embarrassed to ask my mom. He explained to me that 'hair' is normal, as are periods and female arousal.
The way things started was not long after my birthday. Matthew took me aside one day and handed me a little packet of pills,asking me to take them each evening at the same time. He told me that, while my mom looked down on them, some girls needed them when they got to be my age, to help with things like periods and acne. He told me that my mom was mainly against them because they had the added effect of acting as a contraceptive and a chance of increasing a woman's bust size. He promised to keep them a secret from my mom under Patient/Doctor privelege. I accepted them and took them as directed, not really thinking about it.
About two weeks later, while my mom was working and he was on call, he pulled me aside again, saying he needed to give me a check-up on how the pill was working to make sure there weren't any side-effects. We went to my room and went over the normal stuff, checking my pulse, heartbeat with a stethoscope, pupils, ears, tongue, etc. I remember he kept furrowing his brow like something was wrong, making me worried.
He then told me that he needed to double check some things and would need to do a more thorough check-up, asking me to strip. At this point I had never been in less than my underwear during a check-up, but I had no reason to question Matt, so I stripped down naked, feeling intensely self-conscious and embarrassed. He checked my breasts, commenting on how they were still only A-cup and I remember his touch feeling kind of electric. He then asked me to turn around and bend over, which I did, feeling even more self-conscious.
When we were done, he told me that the pills didn't seem to be working, most likely due to a protein deficiancy, explaining that Muscle Drinks and Protein Shakes didn't provide enough daily intake and that I would require a series of expensive shots and medications that wouldn't be covered by insurance. I was stressing out at this point until he calmed me down and suggested that there may be another way, but that he would need my permission.
He explained that the male organ produced the protein used in the medications, almost the same way a cow produces milk, and that coupled with stimulation between my legs, he could produce the protein necessary. As a doctor, he would be able to provide the correct dosage to combat the deficiancy and activate the pills.
Not much of it made sense to me, but I never understood much about medicine to begin with and was more worried about what would happen if I didn't do it, so I accepted. I was still nude at this point and he asked me to lay on my back on my bed with my head on my pillow as Matt took off his pants. I remember my heart was racing, mostly due to worry, but also because of my nudity and his undressing. When I saw his member, I actually thought how it looked like a single udder, except harder and a bit thicker.
Matt reminded me that I was okay, and that our Patient/Doctor privelege still applied, meaning that he wouldn't tell anyone and that my mom wouldn't find out about the pills. Form there he spread my legs with one hand, while the other started milking his member. When he ran a finger over my opening, I remember gasping a bit at the sudden feeling, only for Matt to tell me it was normal to make noise, but that I should try to make the noises into my pillow so people wouldn't overhear. From there, Matt leaned down, putting his head between my legs and licking the top of my opening with his tongue, making me jump and gasp again, telling me it was an old doctor's trick.
From there he continued as I tried to hold back any noise, sometimes holding my pillow over my face while he ran his tongue over a specific spot above my opening. The feeling made my heart beat faster, my body felt hot, my breaths were sharp and my back kept arching while my hips kept trying to get closer to his tongue. This continued for a few minutes until the feeling built more and more and I started to spasm, my legs twitching and my opening feeling like it was tensing and relaxing rapidly while I tried to muffle the moans I made into my pillow.
I lay there for a moment panting as Matt looked at me, smiling. He told me it had all gone perfectly, but that he was having trouble milking his member. He suggested that a woman's saliva would help and that I could milk it with my mouth, which would help things along since I would need to swallow it all anyway. I distinctly remember just nodding dumbly because I couldn't think of anything else to say and Matt asked to open my mouth and turn my head to the side.
The first thing I noticed was it's thickness and that it tasted like licking my fingers when nothing was on them, then a slightly salty taste that Matt later told me was normal, since it meant the saliva was working. From there he guided me, telling me to move my head back and forth, a hand on the back of my head to help me. His other hand moved back to my opening and, as sensitive as it was, it felt like it needed something more. I remember that when he moved his middle finger to the center of my opening, that I reflexively moaned.
Matt briefly taught how to swirl my tongue, to mind my teeth and be careful not to gag. Eventually all of his concentration went back to my opening as he rubbed the top with a thumb and began to slowly guide a finger in and out of my opening a little more each time. It wasn't long before I began to spasm again. I think the spasming hit the right spot, too, because I remember Matt tensing and salty and gluggy start to squirt into my mouth as his member twitched. I remember thinking faintly that Matt had amazing skills as a doctor to control the amount so well.
As salty and gluggy as the stuff was, I swallowed it all and lay there panting as Matt leaned over me, doing the same. After we got dressed, he told me that he would be able to provide me with the dosage as needed, sometimes more often or less often than others and that to help the process, that I should shave between my legs each night the same way I did my legs and under-arms. From there everything went on kind of normally. Not only that, nearly a month later my bust began to grow substantially, from an A-cup to a D-cup. My mom said I was a late bloomer while Matt told me in private that it was a good sign that the pills were working.
Anyway. That's my confession, I guess.
