Emma sat in the observation room and frowned, rubbing her forehead. She flicked through the papers she'd gone through with the test subject only an hour beforehand, and shook her head.
"She swore she wasn't lactating beforehand. Look, her signature is right here." Emma said.
"She must have been. This was only a single dose; for her height, weight and age, she shouldn't have grown much larger than bowling balls." Laura, one of Emma's best and oldest friends and the lead scientist behind one of Size Corps' most popular pill divisions, the lactation inducers, was as baffled as Emma was.
Laura had shoulder-length hair that was currently dyed neon blue, with a stud in her nose and several piercings in both ears. Under her white lab coat she wore ripped black jeans that showed hints of her pale white thighs, and a black shirt representing a band Emma had never heard of. Size Corp had only briefly bothered trying to enforce their strict dress code on Laura before giving up; her expertise and raw talent being far too valuable for them to risk losing. They both looked at the test subject on the other side of the glass.
The curvy redhead was sitting against the wall, legs stretched out straight in front of her, her face contorted in an expression of pleasure. Two massive breasts, easily a beanbag in size each, rested on her lap and pale, engorged nipples sprayed milk onto the floor in front of her. Emma looked down at her relatively new basketball-sized breasts. That was me only a week ago. She thought.
Laura leaned forward and pressed a button on the table in front of her, turning on her microphone.
"Sandy? This is Laura, head scientist behind the lactation inducers." She waved at Sandy.
"Emma here tells me you've put in writing that you weren't naturally lactating before this experiment. Can you confirm that this is correct?"
Sandy flushed red. Milk continued to spray from her breasts, which were swelling bigger by the second.
"I - I mean, not lactating lactating." She groaned.
Laura raised an eyebrow at Emma and turned back to the window.
"Elaborate." Laura said flatly.
"I - I was for a while. My girlfriend was really into it and well... so was I. So I induced, and it worked. But my supply was drying up, and I didn't know what to do. I saw the ad online and..." she trailed off into a moan.
Laura looked at Emma. Emma shrugged.
"She signed it! What am I meant to do, test-milk every candidate?"
Laura looked at Emma, then at her chest. "I get the feeling you're doing enough... test-milking at home." She said, teasingly.
Emma flushed red. When she had returned to work this week, it had been painfully obvious she'd been enjoying some pills from the lab on her own time.
She wasn't surprised there hadn't been repercussions, however. If Size Corp fired everyone who came in one day looking suspiciously bigger or smaller than they had the day before, they would have no staff left. She thought. She looked at Laura, who was just under 5 feet tall and outrageously curvy. She had been 6 feet and slender only a few months ago.
"You can't talk, shortstack!" Emma retorted. Laura laughed. Another groan from the test room pulled them out of their banter.
Sandy's breasts had bloated so far outward that they were covering her entire lower body. All Emma and Laura could see apart from her chest were her head, shoulders and arms. Laura rolled her eyes. Sympathy for lying subjects wasn't one of her strong suits, plus, Emma suspected she enjoyed watching them grow.
Laura pulled her radio from her hip and pressed in the button.
"We need some reversal pills in room 5, please. No hurry."
Emma rolled her eyes, pushing her chair away from the dashboard and standing up.
"I'll get the paperwork." She mumbled.
--------------------------
Hours later, Emma arrived home. Mark heard the apartment door unlock and creak open, and jumped up from the sofa to come greet her. She smiled when she saw him coming, and placed her bag and keys down on the entryway table to embrace him in a hug, both resting their heads on the other's shoulder. They both stood at the same 5'11 tall, and Mark's athletic, lightly muscular build complemented Emma's slender, toned body well.
"Big day?" Mark asked, feeling Emma sink into his arms.
"Soooo much paperwork." She stood up straight and kissed him. "Let me get changed and I'll tell you about it."
A few minutes later, Emma strolled out of the bedroom, having changed from her work attire into a pair of gray sweatpants and a loose white shirt, her oversized breasts still easily visible underneath. Her black hair was done up in a messy bun. She came into the living room and flopped onto the couch next to Mark. He smiled at her.
"So. Paperwork."
Emma rolled her eyes, clearly exhausted by the day. "So there was this woman today, trialing the new round of lactation pills. I ran her through the usual check-in process beforehand, and then we did the test. Except... she was supposed to grow no bigger than basketballs. She ended up filling most of the room she was in."
Mark's eyes widened.
"Really? Bad batch of pills?"
"No, nothing like that. See, she'd signed beforehand to say she wasn't lactating, but she was. She and her partner were both super into it, but she was drying up, so she lied her way into the trial to try and get her milk back." Emma pulled at her collar, the memory of Sandy arousing her. She saw Mark subtly adjust the crotch of his gym shorts.
