Iris followed the doctor down a corridor into a small room. It looked exactly like a normal doctor's office, and the doctor gestured for Iris to sit down on the paper-lined exam table.
"Iris, thank you so much for agreeing to participate in our program. Not only will you be providing us with valuable data for our research, but you will be doing a great service to society by providing us with your breast milk, nurturing a growing industry of human milk production. Please step over behind that curtain and disrobe completely; there is a gown there for you to put on." The doctor gestured to a corner of the room partitioned off with a curtain, and Iris complied. The provided gown was surprisingly soft, and tied in such a way that she wasn't nervous about exposing herself accidentally. She stashed their clothes in her bag and stepped back out to face the doctor, who was finishing prepping a syringe.
"Thank you. This will be the first of your hormone injections to induce lactation and expand your breast size. You will receive them twice a day for the duration of the program. Hopefully you read through the paperwork in the waiting room, but I will reiterate to you that there are some minor side effects to the serum we use." Iris nodded, listening intently.
"First, you will experience a sharp increase in arousal and libido. This is completely normal, and we encourage masturbation, as it can help increase milk production. Second, these injections will cause a noticeable impairment in your cognitive function. As you receive the regular injections, the serum will build up in your system and your cognitive abilities will decline gradually until reaching a plateau after about two weeks. You will most likely become more docile and relaxed, and you may find yourself having difficulty with problem solving, critical thinking, and even reading. After you finish the program, it will take about two weeks for your cognitive function to return to normal. We recommend that you do not work or operate heavy machinery until your faculties have been completely restored. Do you understand?" Iris nodded. Even at the doctor's description of what changes her body would go through, she felt herself grow aroused and had to fight to pay attention. The doctor gestured for Iris to turn around.
"The serum works best injected into the thickest muscle in the body; please turn around and rest your arms against the table." Iris complied, heat rising to her cheeks as the doctor hiked up the hem of her gown. She felt the cool sensation of an alcohol swap on her ass, followed by a sharp pinch as the needle pierced her skin, and then it was over. The doctor let the hem of the gown fall and capped the needle.
"You should start to feel the effects starting tomorrow. As this is your first night here and our participants often have trouble sleeping after their first injection, the shot I gave you also contained a mild sedative to help you sleep; you'll begin feeling that in about fifteen minutes. There is a nurse out in the hallway waiting to show you to your accommodations." Iris nodded and thanked the doctor, then grabbed her bag and stepped out into the hallway, where another woman in blue scrubs was waiting for her. The nurse smiled.
"Hi sugar, it's nice to have you. Follow me, you're in room 17." Iris followed the nurse as she walked down the hallway, turned, and kept walking, before stopping in front of a door marked "17."
"Here you are. You won't be receiving a room key, as you will need to be escorted around the facility for your own safety. You get three squares a day, vegetarian as requested, and me or another nurse will come by to give you your shot in the morning and evening. Once you start producing, we'll have you come down to the milking room as needed throughout the day, okay? Other than that, you can spend your time in your room as you please. Go on, make yourself comfortable," said the nurse, opening the door for Iris. Iris nodded and gave a small smile, then stepped into the room.
It was spacious and well-lit, with narrow windows wrapping around the room at the ceiling letting in natural light. There was a comfortable-looking bed, an armchair, a table with a chair, and a television with a remote next to it. A door off to one side stood ajar, revealing a small bathroom. As Iris stepped into the room, the door gently closed behind her, and she heard the click of an automatic lock.
Iris gulped. She had a fluttering feeling in her stomach, afraid suddenly of what would happen next. She tossed her bag on the bed and stood for a minute, looking down and contemplating her breasts. Still regular-sized... for now. Hopefully this will be a good experience, she thought, and then she yawned. A wave of tiredness came crashing over her, and she made her way to the bed and slid under the covers, flipping a switch on the wall to turn off the overhead light. She could see the moon shining silver through the windows at the top of the room, and she felt comforted as she quickly fell asleep.
