The First Futanari - Doctor's Visit

My name is Emily, and I am what you would call a 'futanari'.

A girl with both a penis and a vagina, both being functional genitalia.

I used to be able to relax after-school, and wank out a couple of rounds. Fortunately, my many study sessions with Emma have ended that. She has become addicted; like clockwork we walk up to my room and she gladly spreads her legs for me. We never make it to our homework before she grabs my cock out of my pants and enjoys numerous fillings. During our multiple-hour fuck sessions, I pound her brains out. She isn't fit to drive after the sheer number of orgasms she has, and I have to get her home afterwards.

Over the summer, I went to Dr. Rosswell's office for a routine check-up.

Emily went with me, in order to check for pregnancies. She didn't seem to be, however after so many loads, we couldn't be sure. After confirming that she was indeed not prego, Dr. Rosswell recommended getting an IUD, just in case. I agreed, I couldn't have her getting pregnant and neither of us wanted me to wear a condom. Even if we did, we couldn't find the size we needed anyway, as my dick was too large. I was now sitting at an amazing 14 inches, and Dr. Rosswell commented that I should keep growing. She'd done the calculations, and she predicts I'll have a 20 incher by the time the first year of college ends.

Dr. Rosswell and her colleagues also did some tests on my semen, and they concluded that it has some of the highest sperm count they'd ever seen, and it's by complete luck and God's will that Emma hadn't gotten pregnant.

The scientists say that my thick baby-batter contains an unknown, un-recreatable de-aging chemical, and they wanted to pay me big bucks to supply them with some testing material. I signed the forms, and Emma was glad to help retrieve it, but I had other plans. Having had a crush on Dr. Rosswell since the start of junior high, I specifically requested that it be her that collects my special semen.

She objected to the idea, knowing that I had a vendetta for her, and after how much she had sexually tortured me over the years, I was going to make her pay. But, she wanted my sweet liquid for her experiments, and deep down, I knew she wanted it for other reasons.

We travelled to a special building for the procedure, and they were very serious about contamination. I had to walk into a room where women cleaned me with special brushes. They were obviously surprised at my size, but made it seem professional. I was not given clothing, but was guided by men in airtight suits to the room. There was an empty room with a bed, sink, TV, and mirror. I was told to hold off from orgasming for as long as they told me, although they had no idea how difficult that was going to be for me.

Over the course of senior year, I had gone from what used to be a small clitoris to a 14 inch penis and a matching pair of tennis ball sized testicles. My sexual energy was twenty times what a normal male would have, and its because women aren't designed to have testosterone running through their veins. This causes my sex drive to be so grand, and that essentially makes me the best at everything between the two sexes.

I was unaware at the time, but I had signed up for twelve whole days and nights of no interaction and some sexual repression drugs that they gave me. My penis was in purgatory, half hard and half soft during the whole thing, I think they also gave me some drug that increased semen production. I was bursting at the seams; my balls were hard as rocks and had grown exponentially to the size of soccer balls. I couldn't stand anymore, and laid on the bed legs wrapped around my throbbing testicles. It wasn't painful, and actually felt pretty damn good. However not being able to come or stand up really hurt my mood.

Normally, testicles don't grow during abstinence. However, thanks to my extreme circumstances, my balls aren't constrained to a specific size. This allowed them to grow as large and full of semen if I don't ejaculate.

The pneumatic door clicked and shuddered open. Dr. Rosswell walked in with her team to take pictures of my status. My penis was visibly throbbing, and the male doctors seemed to pick up on my uncomfortableness. The air was full of my pungent aphrodisiac, but the suits the doctors were wearing protected them from the effects.

As her team walked out, Dr. Rosswell began to look nervous. She pressed the buttons on the door, and it locked her in. The lights turned to a shade of pink, and she began to take off her suit. Helmet first, and she wasn't prepared for how fast my aphrodisiac overcame her. She slowed down as the effects of my aroma took control of her body, and she looked deep into my eyes as she removed her protective suit like she was slipping out of a dress.

Instant save to the spank bank.

I thought of something that might increase heat of the situation. Once Dr. Rosswell was fully nude, I reminded of her first encounter with my dick. I told her that she had been the one that made it that way, and she responded that since it was her fault, that she'd make it up to me. Sluttily waltzing over and jumping onto the bed, she wrapped her enormous breasts around my cock, and slowly spread around the pre-cum that was streaming out of the tip with her fingers. I hadn't come in over a week, and my dick was sensitive, and because of this I came within two minutes.

She was surprised at how fast her hand/boobjob had worked and almost disappointingly reached for a tube attached to the wall. She placed the tube on the head of my cock and continued moving her large wet tits.

UP and DOWN, that's all I felt until I came; I could feel my testicles squeezing the thick baby-batter out of themselves. As the weight of my balls slowly decreased, Dr. Rosswell crawled seductively towards me on the bed, sat on my chest, and began to lick herself, and it turned out she had crazy flexibility. Her long legs and gorgeous ass twisted until her body became a glazed pretzel as she licked her thighs with such delicacy, that it seemed she was cover in frosting. She leaned down and started a heated make-out session with me.

She whispered "I've been wanting to do this with you since you made it over six inches. It was against protocol then, but the opportunity has arisen."

I had slowed in my cum spurts, and in response the tube retracted back into the wall. My soft penis fell onto Dr. Rosswell's smooth back and between her ass-cheeks and cum continued to slowly ooze out as we kissed. The warmth from her lower back was entirely different from the feeling of her tits, and I rapidly began to grow again. Her sultry moaning hit me in all the right spots. Once I was hard enough, I lifted her and slammed my 14-inch ladyrod directly into her tight baby-making hole.

The perfect O she made with her mouth spelled the answer out. After not moving for a little, so she could get used to it, I began to ram upwards into her. She had frozen, and her tits were looking so delicious, so I made the decision to lick her. The combination of the aphrodisiac enhanced nipple-licking and my constant fucking, she had what seemed to be the largest orgasm she'd ever had. She vibrated, writhed, and squeezed on my dick, and completely lost control. She began riding me, with all of her might, matching my rams with slaps. Her moaning was extremely enticing, and I thrusted harder in response.

I began to feel myself getting close again, so I told her. Dr. Rosswell didn't answer, so I assumed she had lost it. In a last-ditch effort, I lifted her off, to her horny dismay, and plugged myself into the suction pipe. I came into the pipe, kind of disappointed by my responsibility. To my surprise, Dr. Rosswell unplugged my dick from the pipe, sending semen everywhere and shoved my cock into her pussy. I fell onto the bed in surprise, and even the scientists viewing us began to yell at he over the intercom.

Dr. Rosswell screamed back at them, in complete ecstasy "I DON'T CARE! I WANT THIS BIG FAT FUCKING HORSE COCK TO FILL MY WOMB WITH ITS THICK SEMEN! OH, MY FUCKING GOD!"

In a half shocked, half lust filled move, I began ramming my cock, which was still pumping my lady-spunk into this woman, even harder, causing Dr. Rosswell to moan even louder. She was the most prim and proper person I had ever met, and the fact that I turned her into a moaning, sweaty, cum-filled mess was enough for me to orgasm a third time. My white, steaming liquid that I shot directly into Dr. Rosswell womb was the thickest baby-batter I'd ever felt leave my cock, and must've been a result of the drug the scientists were slipping me through my food.

It filled her to the brim, and once that was full and I noticed her stomach expanding with the sheer amount of semen, I pulled out and filled the pipe with best cum I'd ever produced. As I was doing so, I looked over at Dr. Rosswell who had fallen asleep, ass-end up, dumping cum out onto the flooring. It was so hot, that I went in for thirds, fourths, and definitely fifths.
