After my incident with Delia, things got really interesting for the next month or so. I was nearly 11 inches at this point and I was still on the same regimen of pills and the weekly shot, but Dr. Jensen was adamant that I was measured in every way possible each time I visited. And it wasn't just Delia who did, but the two silent assistants, who I discovered were there on an internship, also took their turns. I also finally found out their names. The cute, very petite Asian doctor was Mingxia (she went by Mia) and the gorgeous, voluptuous red head was Keegan. All three of Dr. Jensen's assistants were definitely very young, the good doctor was in her 50's, but didn't look it! (Boy was I wrong about her age when I first saw her!)
One month after Delia and I fucked, entering month 5 of the trial, Dr. Jensen was the one who met me in the reception area. Usually it was Delia, so I thought that was odd. I was about to say something and she cut me off.
"Please come with me, Mr. Simon, I'm by myself today and I have much to do."
Shrugging my shoulders I followed her into the lab, it had oddly become a very comfortable place for me to be.
Once I undressed, which was not automatic for me, I asked, "Is everything all right doc?"
She pursed her lips and said, "You know I dislike you calling me 'doc', right?"
"Well, I keep saying you can call me Jimmy and you never do...."
She sighed deeply and relented, "Fine, Jimmy. Better?"
I smiled broadly and said, "Yes, thank you, doctor."
Though she tried to hide it, I saw her smile a little as she turned away to get the syringe and bottle.
"Now, Mr..... er, Jimmy, you know the drill. I am going to give you your shot and then I'll proceed with your measurements. Based on everything I've been reading, I am quite impressed with how well you've adjusted to your new self."
I blushed slightly and said thank you as she gave me the shot. This time is was a little different though. Every other time I had an small warming sensation right afterwards and short dizzy spell. This time, however, I felt like my muscles were on fire, like they were over energized.
"Uh, what's going on???"
Dr. Jensen looked at me and exclaimed, "Oh don't worry, this is the final stage of injections. You'll receive these from now on. It's a series of 8 injections that will allow your changes to become permanent without incident. You need to continue with the pills, but only 1 a day from this point forward. The sensation you're feeling right now will subside shortly, it's to help your body."
As she was talking I could feel things returning to normal, but I also noticed that I was getting extremely hard too. Something Dr. Jensen couldn't miss.
"And I see that the desired effect has occurred as well," she said. "This was not unexpected, but had it not happened, that would mean your body would not have accepted the changes it has undergone. So this is very good news!"
I smiled and said, "So if I keep up for the next 2 months, I won't go back to being scrawny?"
"Oh no! You do not have to worry at all! But, as I said at the beginning of the trial, your height will not increase unfortunately. Now then let me get to these measurements so you can be on your way and I can get back to my research."
I instinctively stood up, allowing her to do what she needed to do. It had gotten to be so clinical with the other three, I wasn't really paying attention to what the doctor was doing at first. But when she got to my hard cock, I noticed something was different with what she was doing. I looked down and I saw her just staring. I recognized that glazed look, it was the same one Delia had right before I fucked her throat. I smiled and I got an idea.
Without saying anything, I carefully placed my hand on the doctor's shoulder and she broke the spell for a second.
"Are you ok, doctor? You seemed distracted."
Looking up she said, "Oh, yes, I was just, uh, making sure I was thorough. Yes, very.... um, thorough...."
And with that her eyes closed and I could see her taking in the full amount of the pheromones I was emitting. With my hand still on her shoulder, I moved a bit closer and gently pulled her towards me. She gave me no resistance whatsoever. At this point, I was at my full length of 11 inches and her mouth was barely a half inch away. I then leaned in and pushed the tip of my cock on to her lips. She knew what to do and greedily took it.
She was mine.
For the next few minutes I let her do the work. I wanted her to get used to the size. I was surprised that she was able to take as much as she could, she obviously had some experience! It was then time for me to take over and completely own her, like I did Delia.
I grabbed her by her gray hair and pulled her off my cock. She tried to fight it, but I pulled it out of her mouth with a loud pop.
"NO! Please I need it, oh please!!!"
"You need it, doc? Or should I just start calling you by your first name now, Andrea?"
"Oh God, yes, whatever you want!"
Even though she towered over me at 5'10", I was able to pick her up with ease. I turned her around and bent her over the examination table. I flipped up her skirt and I saw a pair of very drenched panties. I reached in and ripped them off of her and she moaned loudly. Her extremely wet pussy now totally exposed to what I was going to do.
"Relax, Andrea, it's time for your injection now!"
And without any softness at all, I drove in deep as deep as I could and I heard her scream! But it wasn't a cream of pain, I felt her cum immediately as I plunged in deep. If I hadn't been as deep as I was, I know she would have been squirting.
I was unrelenting. I don't know what came over me, but I wanted to break Dr. Jensen at this point. As I fucked her, I reached down and grabbed her hair, pulling back hard. I felt her pussy clench again and she came once more.
"You like my big cock, bitch? I'm going to keep fucking you until you pass out."
All she could do was groan out what sounded like a yes.
For the next few minutes I was an animal, just pounding her cunt, feeling her cumming over and over again. I felt her legs give way at some point, but I had her pinned to the table. I started to feel that familiar boiling sensation in my balls, but I wasn't going to pull out. I kept thrusting in and out harder and harder, and by now her pussy was almost convulsing from cumming constantly. I heard her whimpering with each thrust. And then I gave one last push in and I came deep into her womb. I knew by now that the amount of cum I produced was over half a cup, so I could feel it spilling out. Once I was done, I pulled out and released the good doctor.
Now free of her sexual pummeling, she crumpled to the ground. Thoroughly exhausted. I stood over her, my semi-hard cock hovering over her face. Surprisingly, she opened her eyes and looked up at me. With great effort she tried to sit up as best as she could and leaned into gently kiss the head of my cock.
Collapsing back the floor, I saw her mouth the words, "Thank you."
I leaned down and kissed her on the forehead and said, "You're welcome, Andrea. See you the same time next week?"
All she could do was weakly nod.
