Author's note – this is the third instalment in a planned series of 5, and serves to tie together the events from the first two. Contains breast expansion, futanari, nipple penetration, macrophilia and microphilia.
When Hannah turned up at work one Monday morning with much bigger boobs, most people had been unable to extract much information out of her. She'd deflected their questions with veiled suggestions of a sexual harrassment lawsuit, which had shut them up pretty quickly. Abi, however, was the one person at work that she considered a genuine friend, and to her she had confided the whole unbelievable story.
Which is why Abi now stood in front of a heavy wooden door in an old part of town, raising her hand to knock against the weather-beaten surface. The story that Hannah had told seemed too far-fetched to be believed, at first, but the evidence could not be denied that Hannah had somehow managed to go from being completely flat-chested to healthily-endowed over the course of a weekend, and the residents of this building were the cause.
As Abi's knocking echoed around inside, she heard footsteps approach the door. The door opened a crack and a face peered through the gap, a fairly tall, thin woman with dark hair and brilliant blue eyes.
"You are Abi?"
"I am."
"Follow me. Close the door."
The face disappeared and Abi pushed the door open and walked in. She could see the woman walking away from her – this must be Maria. As Abi followed her through the corridor and around a corner, she watched carefully for proof of Hannah's story. It was true that Maria had something large bundled up in a sarong wrapped around her waist. According to Hannah, that large something was Maria's cock, but the thing that Abi could see was far, far too large. Or, was it?
Abi followed the corridor into a room, where Maria was stood, waiting for her. She had a stern-sounding voice, with an Eastern European accent.
"Welcome. I am Maria."
"I guessed. Hannah told me about you."
"Ah yes, a satisfied customer. You wanted to grow as well?"
Maria looked Abi up and down. Whereas Hannah had been clearly flat-chested, Abi actually had a rather well-proportioned figure, and Maria wasn't sure why she would be so desperate to be endowed with larger breasts. Still, each to their own. Abi was fairly thin, which was surprising, because she spent most of her life sat in front of a computer, but for the time being her physique did not betray her lack of exercise. She wore her blonde hair tied up, black plastic-framed spectacles, and minimal makeup.
"Actually, I must admit, I came here under false pretences."
Maria's glare could have cut glass. She was not a woman who was used to being manipulated.
"Out. Now."
"Wait, wait, hear me out. Just a minute, please. Hannah told me about you, and I wanted to know more."
"I am a private person, I do not wish to talk."
"Please, don't throw me out. I find you fascinating. Ever since Hannah told me about your... body... I've been barely able to sleep. I'm itching to know."
Maria thought for a second, and then spoke. Something about Abi seemed sincere, and for once she found herself inclined to talk.
"Hannah is a good girl. If you are a friend of hers, you are probably okay too. Sit."
Maria gestured to a large leather footstool in the middle of the room, and the two of them sat down next to each other.
"A few years back, I came to this country with my boyfriend. He was a scientist, a biologist, working in an experimental field. I didn't know much about it. He was never the nicest guy, but as time went by he treated me worse and worse. But there was nowhere for me to go, I could not leave him. One day, he invited me to his laboratory. When I got there, he was drunk, and alone. He gave me a little glass of something to drink, and once I had swallowed it all he told me that it was full of little robots that could redesign the human body, right there."
Abi was stunned. This was like something out of science-fiction. Was Maria teasing her?
"I just looked at him. A part of me didn't believe it, but then another part of me knew that if he was telling the truth, then he was now capable of doing something horrid to me. I begged him to stop, I got down on my knees. He slapped me, spat at me, told me I was worthless. He told the computer to give me a dick so I could go fuck myself, and then told me to leave before he killed me. I had no choice, I left. As I ran out of the laboratory, I could feel it in my clothes, he was telling the truth."
"And was it always that big?"
"No, it was a normal size at first."
"But your cum makes things grow. Hannah never explained how that happens."
"I don't know either. It was an experimental research program, maybe something went wrong somewhere."
"Where's your boyfriend now?"
"I don't know. I never went back to him. It took me a long time to get back on my feet, and since I met Megan I've never been happier. I stay away from where we used to live. I don't want to ever see him again."
"Would you change back, if you could?"
Maria sighed and sat quietly for a short while. It wasn't something she'd really thought about.
"No, I would not. Things sometimes happen the way they do for a reason. I wouldn't change a single thing."
Maria waited for Abi's next question, but Abi merely looked at her feet. Eventually, Maria spoke again.
"So there, that's my story. Why do you want to know so badly?"
Abi steeled herself – she knew that the next question was a big one, but it had to be asked sooner or later.
"Maria, I want to go to the lab. Will you take me?"
Maria thought for a long time before answering.
"I do not know if it is even still there. But I would not go. I don't want to bump into him again. And why do you want to go, anyway?"
