Wednesday morning came in a flash. I quickly showered and shaved, grabbed an energy bar, and ran out the door. I was late.
I practically sprinted down the halls to Dr. Hu's office, bursting through the door, hoping she wouldn't scold me, which she does often as if she were my mother.
"Why are you panting so heavily, Ben?" The doctor asked. She stood by the one window in the room, which looked out over a small courtyard.
"I was running late," I said, catching my breath. "I'm sorry, I woke up late, and..."
"It's okay, Ben. I don't need the whole story. I'm just glad you're here. Have a seat." She gestured to the chair at her desk as she approached from the window.
Sheri Hu was a very beautiful woman for her age. She was petite and kept herself in great shape, as I found out when I ran into her at the program's fitness center two weeks ago. Before that, I had only seen her in the white lab coat she wore to work every day. In gym clothes, however, her shapely figure was very much on display. She had a firm, toned butt, and an ample chest that her sports bra had difficulty hiding. Being of Chinese descent meant her facial features did well to hide her true age, with soft, smooth skin, high cheekbones, and thin, almond eyes. It was shortly after I started the program that I ran into her at the gym, and was only mildly attracted to her, as anyone three decades younger would be, mostly impressed by her ability to stay in shape. But in the present, as Dr. Hu rounded her desk to sit across from me, I could make out the subtle hint of her curves and something stirred inside me. My cock started getting hard.
"As we discussed, you'll be given three more weekly injections, starting today. These will be unlike the first three, as they are more potent," she said, sitting.
"More potent?" I raised an eyebrow.
"Yes. You see, as your body changes due to the treatments, it requires stronger doses to achieve the results I'm after."
"And what are the results you're after?" I asked, eyebrow still raised and cock growing harder. I couldn't help thinking what her tits looked like under her lab coat.
"Again, as we discussed, there's higher demand, Ben. You do understand what that means?"
I thought for a moment. Demand, in this case, would be for more pregnancies.
"I think you mean more girls are signing up, right?"
"That's correct," she smiled. "Now how do you suppose we keep up with demand without having more donors enlisting, hmm?"
"Gosh, I dunno. Maybe have us work more sessions?" I offered.
"No. That wouldn't do. You would be fully spent by the second session in a day. Try again," Dr. Hu said, now leaning back in the chair, with a sly smirk on her face. She knew I was stumped.
"I give up, okay. Just tell me," I pleaded, weakly. My erection had subsided now that I was taking this a bit more seriously.
"My aim is for you to go three or maybe even four sessions in one day, but that will be down the road. The treatment will do the work to your body, but your mind needs work, too. That's where Sandra comes in."
"Whoa, wait a minute." I stood up and paced the room, pondering the doctor's words. "Four sessions in one day? That's, like, sixteen girls!"
"I know it's hard to fathom, Ben, but I promise you, you will be more than capable. For the time being, however, you'll be limited to one session a day, twice a week. You'll need to focus on controlling your body, with Sandra's help, of course."
"Okay, I'm a little confused. I'm still not sure why Sandra has to be involved. I mean, I think she's great and all, but is it necessary? What exactly is she going to be doing?"
"Well, until you both get an understanding of the effects of the extra treatments, it's really up to the two of you. I will be here to help if you need it, but I think you'll be just fine."
"Well, that doesn't help," I said, plopping back down in the chair.
"Don't get too comfortable. I have other donors to see. Follow me to the exam room next door."
Dr. Hu led me to a small, neighboring room which was your typical exam room. Instead of having me sit on the exam table, she had me sit in a chair against the wall and lift my shirt.
"Okay, Ben, this will feel no different than the others. Just a little poke in the belly," she said, producing a small syringe from the tray beside her.
She punctured my right side, about halfway between my belly button and my crotch. It didn't hurt any more than the prior injections, producing a minor, dull ache. The doctor put a small bandaid over the injection site.
"There you go, nothing to it. Now listen, Ben, you will feel some uncomfortable pain, not unlike your prior injections, though perhaps slightly more intense. If, for any reason, you experience very sharp pain, nausea, or vomiting, call me immediately. Any questions?"
"When will my next session be?" I asked.
"Ah, yes. I almost forgot. Wednesday will be your next session, 11 a.m. You'll need to rest today and Sandra will see you tomorrow night, as I've instructed her to begin coaching you then."
"Okay, that's it, then. I'll see you in a couple days."
"Yes. Let me give you one suggestion before you go." Dr. Hu then walked up and stood uncomfortably close to me. She grabbed my junk and said, "Try to make the last one, the best one."
Dr. Hu's advice stuck with me the whole bus ride home. I had no clue what she meant by it. What I did know was the treatment was kicking in, much sooner than the previous doses. I felt an ache in my lower abdomen and a slight stabbing pain in my scrotum. Luckily, it did not get any worse as the day went on. I obeyed Dr. Hu and lazed around the house, watching a couple of movies and napping twice. I was awoken from my second nap to a call on my wall screen. It was Sandra.
"Hey, how's it going? How was your treatment?" Sandra asked when her face appeared on the screen. She looked more beautiful to me, her skin was glowing on the high-definition screen.
"Good, I suppose. It's made me tired, and a little sore. But I suppose that was to be expected. How are you? You look radiant," I said, not sure how she would take the compliment from a coworker.
"Oh, really? That's very nice of you, but I think your screen must have a filter on it or something." We both laughed.
"No, no filter," I said.
"Okay, then." She smiled. "So, what did Dr. Hu tell you?"
"Not much. Just that we need to work together to help me achieve the impossible."
"Yeah, that's pretty much what I got out of her, too. I gotta say, I'm a bit nervous. I don't have the slightest clue as to how to help. Well, not that I'm helpless or anything, but I'm not sure what the outcome of this should be. Does that make sense?" she asked.
"Totally! I agree. I mean, she said her goal is for me to go three or four sessions a day! I don't know how anyone could possibly do that?"
"Hold on, she said what? Three or four sessions a day!?" Sandra's mouth was agape. "Ben, she told me her goal was to have you cum in as many as ten girls in one session."
"Are you serious? That's insane! There's no way in hell I could do that! She's out of her mind."
I sat upright on the edge of my bed and pondered the situation. I had no idea what Dr. Hu was thinking, but the more I thought about it and thought of having Sandra help me, whatever that meant, the more I was intrigued.
"Listen, I'm still up to try whatever it is Dr. Hu has in mind for us. What are your thoughts?"
After a long pause, Sandra spoke, "Truth is, I like you, Ben. I'm very much attracted to you, but I don't want that to get in the way of our work. I'll help, but we have to be professional about it."
"Oh, I understand, totally," I smiled, my excitement obvious. "I really like you, too. I promise to keep it professional. So when do we start?"
"We can start tomorrow. I have some errands to run in the morning, so after lunch would be okay."
"Perfect. How about two o'clock, my place?"
"See you then, take care," Sandra smiled and waved, then disconnected.
I exhaled and was shocked to realize I was fully erect, sitting on the edge of my bed in just my underwear. I was accustomed to Sandra seeing me practically naked, since she was there to see that everything was in order before I began each depositing session, but being on a private call like that and her possibly seeing me with a raging boner was rather embarrassing. I crossed my fingers, hoping that part was hidden off-screen.
My stomach was a wreck of nerves and anxiety as the night went on. The aching in my nether regions persisted, becoming an afterthought by the time I finally hit the sack. I slept like a rock.
I awoke Thursday at 11:00 a.m., several hours past normal. I would be home from the gym and showered already. The aching I felt the previous day was gone, however, it was replaced with a tingling in my testicles and the base of my penis. I went to the bathroom and, while I expected to see my balls had grown, I was not prepared for the amount in which they had. After my previous injection, weeks ago, my nutsack felt like it had two golf balls inside. Now, my testes were almost as big as pool balls, stretching the skin fairly tight. My dick looked like it had grown some, which was expected, though the full effects of the treatment wouldn't be seen for another day or two.
I hit the gym, late, to do upper-body workouts, then went home to shower. As I lathered myself, I couldn't help but caress and stroke myself, admiring my big cock and balls. I wondered what Sandra would think when she saw them. She never did make any mention of my junk at work, which was most professional of her, but I wondered if she ever thought about me after hours. I was getting hard thinking about it. I let myself cool off and finished my shower, heading to the kitchen for my usual protein shake when my wall screen next to the sink came on, a voice call from Sandra.
"Hey Sandra," I answered.
"Hi, Ben. Would it be okay if I came a little early? I'm not far from you now, and I'd rather not go all the way back home."
I looked at the time and realized it was already 1:30 p.m.
"Sure", I said, looking down at my naked self, chuckling, "I'm just hanging out."
"Um, okay. I'll be there in about five minutes. See you then." The call disconnected.
I didn't have time for a shake and ran to my room to throw on some clothes. I grabbed a pair of gym shorts and a tank top, opting to forego underwear. The door chime sounded moments later.
"Wow, that was quick. You must have been really close," I said as Sandra stepped through the doorway into my apartment. She looked amazing in street clothes, only wearing a purple sports bra and tight, black gym shorts. I was used to seeing her in her work uniform, which hid her athletic figure. She was roughly five-nine, and rail thin, but with subtle curves in the right places. Her sports bra squeezed her smallish boobs just enough to form a hint of cleavage. Sandra brushed her long blonde hair over her shoulder and hugged me. I hoped she didn't feel my growing erection against her thigh.
"Yeah, I was just around the corner getting some makeup from that new store, Lush."
"Oh, right. They just opened, I think."
"Last week. I wanted to get some of their mascara, I've heard it's great."
"I wouldn't know anything about it," I laughed. "So, anyway, welcome to my apartment."
"Thanks. It's nice," Sandra said. We both stood silent for an awkward moment.
"Well, how should we begin?" I asked.
"Hmm, I'm not sure." Sandra's demeanor quickly changed, her face showing real seriousness. "I suppose, firstly, we need to get you into an aroused state, just like you would be heading into a session?"
I tried to get myself into the same frame of mind, though it was hard with Sandra here helping, wearing what I deemed a sexy outfit. I was only accustomed to the help of the priming device before a session.
"I agree, though I think that would best be achieved by a primer. We don't have that luxury here," I said. We both thought for a moment and then the spark of an idea flashed on Sandra's beautiful face.
"I can try to simulate the primer," she said, shrugging her shoulders. "Would you be okay with that?"
I tried to hide my excitement and be professional, but failed.
"Of course I would! I mean, yes, that would be okay, if it's what you think would be most helpful."
"The primer's main function is to keep you in a state of arousal to help increase sperm production. I'll try to replicate that, and for the full fifteen minutes, just like before a session. Take your clothes off."
I enjoyed how direct Sandra's instructions were, and I did as I was told, removing my tank top and shorts. My cock was at half-mast, clearly bigger than it was just the day prior.
"My goodness, Ben," Sandra practically gasped. "I knew the treatments caused some growth down there, but holy shit."
