Desc: Sex Story: This story is not related to my story "Breast Enhancements", but is infact an offshoot of "Placebo": More messing around with mother nature. "Placebo" need not be read prior, but it will provide a little different flavor (NPI) to the story.

HAZARDS TO HUMANS AND DOMESTIC ANIMALS: Causes substantial but temporary eye injury. Do not get in eyes or on clothing. Harmful if swallowed. May irritate skin.


I signed up for Sandy Greenhall's project because it was free. I'm in my third year here at the university, and I'd given up on gymnastics last year, choosing to focus on the academic path. At 5'5" and 105 lbs., people say I'm pretty, but I have heard the remarks about my small breasts, and it does bother me. So, I signed up for the study testing those herbal supplements that are supposed to make your breasts larger naturally.

I didn't get to start as soon as some of the others, and when my turn came, Sandy told me that some of the participants were encountering some side effects. As a result, she wanted to cut my dosage down to match my petite figure. It took some doing, but I convinced her not to do that. I finally won her over by explaining how my athletic background has given me a higher metabolism.

Then she told me about the side effects and I almost laughed. I mean, come on: "Increased sensitivity" and "heightened libido"? Is that supposed to be bad? "Slight increase in aggressiveness" didn't sound too bad either, and I was more eager than ever to try these things. My boyfriend at the time was a bit of a jerk. I could see his eyes wander every time a pair of tits walked by; and, as we didn't see each other often, I thought he was probably messing around on me. I really wanted this study to work for me so I could see his eyes when he saw my development; then watch his reaction as I dumped him like a rock.

Twice a day I visited Sandy's office for her to administer a dose and wait for a bit so she could monitor any additional side effects. I was finding that my nipples were more sensitive, and I was getting more aroused with each dose, but I played down the effects when I discussed them with Sandy. I was afraid she might cut my dosage. She could see, though, how it made my nipples stand out, and when she did her measurements, they got even harder. So I did admit the "slight" increase in sensitivity and that I had felt a "little" more sexy.

Sandy was cool though. She was very happy with my progress and very encouraging throughout. I was really happy the fifth day when I got out of bed and thought I noticed a slight increase in size. They felt fuller in my hands as I cupped them (yes, they're A cups, but I could tell the additional swelling was not muscle). I was really excited about it and hurried to get dressed and over to Sandy's to show her my improvement.

When I got there, I knocked twice on the door and went on in not thinking. Inside, another girl was sitting on the couch with her top off and Sandy was kneeling between her legs examining her breasts. Sandy was very close and seemed to be pinching one nipple.

Sandy was quite startled by my interruption, and I hurried to explain, "Oh, I'm sorry, Sandy! I was just so excited this morning, that I couldn't wait to show you. I didn't mean to·" Sandy seemed to relax. The other girl's reaction had been different. She sat still with her mouth slightly open, her only reaction had been to turn to look at me and then get a little wide eyed.

Sandy recovered quickly and set me at ease. "That's alright Kay, since you're here already, come on in and close the door. This is Julie. Julie this is Kay, the next in line this morning." She said while standing.

I said "Hi" to Julie, and she nodded in return, closing her mouth and starting to look a bit uncomfortable with the situation.

I closed the door and Sandy said to me, "Well, since you're here, get your top off and show us what has you so excited. It's only fair to Julie."

I smiled an apology to Julie and pulled my T-shirt over my head. Julie looked on quietly and Sandy said, "Yes, I do think your starting grow a bit." I looked over at Sandy and stared for a bit.

She was doing spectacular. She must have been a large C cup, and her nipples stood out proudly on breasts that seemed to have no sag. I said, "You must be very pleased, Julie. You look fantastic."

Julie's face perked up a bit and she smiled, said, "Thank you," and glanced down at her chest.

Sandy jumped right in. "Julie is one of my earliest subjects and doing wonderfully." I saw Julie blush a bit at that. "She's been on the treatment for three weeks now and she's gained one full cup size. Since switching to a more accelerated treatment she has encountered a diffent side effect." Julie seemed to flush a deeper shade and Sandy continued, "Oh, don't be worried, Julie, it's a natural thing and most likely only temporary. Kay, come here let me show you."

I sat next to Julie on the couch, and Sandy knelt between her legs again. "You see, Julie has started to lactate a bit. Yesterday I showed her how to express using her fingers, but she's been having trouble with it, haven't you?"

Julie nodded and said, "Yeah, they're beginning to feel a little uncomfortably tight, and it hurts when I try to use my hands." Closer now, I could see some wetness around the nipples and the one that Sandy had been looking at had a large drop forming at the tip. Sandy again used her fingers and a several drops came out as she squeezed a bit, but Julie made a sharp intake of breath.

"That still hurts?" Sandy asked, and Julie nodded. Sandy said, "Hmmm. There's another way we can try to give you some relief." And then she leaned in close and took the nipple in her lips. I could see her tongue moving underneath as she made a gentle sucking motion, then closed her mouth over the nipple. Her mouth worked a little more and I heard Julie sigh softly.

Sandy released the nipple and asked, "How was that?"

Julie replied, "That was better, I can feel a little relief."

Through this exchange I sat quietly. My eyes had gone wide when I saw Sandy take the nipple into her mouth, but I realized that Sandy was a graduate student in medicine, and she had to know what she was doing. I did stare a bit, though, and I could feel the air on my nipples as I watched. I think I got a little wetter too.

Sandy glanced over at me then back at Julie. She said, "Well, maybe if we can get you going it will be easier for you to use your fingers. Kay? Would you be willing to help?"

I swallowed and looked at Sandy. Then she explained further, "Julie has a class in a few minutes and needs to get going. If we can relieve the pressure a bit, she'll be better off the rest of the day." This made sense and then Sandy motioned me closer and said, "Here, just be very delicate, no teeth, and gently suck. It's quite natural, and very sweet."

I was a bit mesmerized by the whole thing as I found myself leaning in. I looked up at Julie, and she had a strange look on her face as she watched me with heavy lidded eyes. Then I closed my lips over the nipple and gave it like a little sucking kiss. Sandy gave me more encouragement, "There now open a little further. Use your tongue underneath and try to draw it out, then suck a little harder."

I followed her instructions and then felt a couple of drops on my tongue. I gave a little startled twitch, stopping my actions; and then I tasted the sweetness of it. I let go and asked while looking up into Julie's eyes, "Was that OK?"

Julie nodded and gave an, "Mmm, Hmm."

Sandy said, "That's perfect. Go ahead and continue and remember to be gentle." Then she moved to take the other nipple in her mouth and begin sucking.

Unsure of my actions, my eyes were still on Julie's, as I took the nipple back into my mouth, and repeated my actions. Julie watched for a couple of sucks and then her eyelids seemed to droop and she leaned her head back. I closed my eyes and continued to suck. After a few swallows, I realized I was feeling very wet and hoped it wasn't showing on my shorts.

Julie didn't have very much milk and soon we were through. Julie was breathing a little fast, but said, "Um, thanks," as we stood up.

Sandy moved over to the cabinet and said, "Why don't you give her a hand getting dressed." So I helped Julie to her feet and handed her bra to her.

I slipped my own shirt back on, and Sandy handed me the little container with my pill in it and a cup of water, saying, "Here, go ahead and take this; and then if you would, please, could you walk Julie to her class, and see that she gets there OK? We'll measure you next time."

I was in a bit of a daze, but I said, "Sure," and we were quickly out the door. We walked most of the way there in an awkward silence. Finally, I broke the silence by apologizing again for bursting in on her and any embarrassment I caused. She was nice but still appeared embarrassed as she told me not to worry about it. I tried a few more attempts at conversation, which were met with short, nervous replies. About the only thing I learned from her was after I told her I lived in Williams Hall. She also lives in that dorm, but on a different floor.

After I left her at her class, I remembered about my shorts, but didn't see any signs on them. Still, I headed back to my room to change. Back at my room, I decided I needed to get myself off before heading to classes. I came twice, and I kept finding myself thinking about the taste of Julie's milk.


When I saw Sandy later that day for my evening dose, she was very understanding and explained more. She told me that by her own request, Julie was in a separate aspect of the study, receiving a higher dose, and side effect with that may include temporary lactation. We sat together on the couch and spoke for some time about the study and breasts, sharing some of our desires.
