Erin looked at the remote again. Her mind had progressed along with her body, and she was understanding new possibilities, new chances that she could do. She scanned the options on the screen, trying to decide what to pick.
Then one caught her eye. It read 'Pregnancy'. Erin knew that these changes were reversible, but she decided to file that away for later. Then she selected one she had always wanted to in the last 15 seconds. Every since she had accelerated her growth, she had grown to like the idea of becoming a human cow. This was a term that described a women, who went on hands and knees and who got fucked often and had breasts which touched the floor and produced copious amounts of milk. Then she activated the machine.
The sides of the machine lit up with the wonderful warm glow again, and Erin felt . . . nothing. The light continued to shine on her body, and she started to feel slightly depressed. She felt her back straighten slightly, as if getting ready for something. But nothing happened. Then her A cups began to swell. They grew larger and larger, growing heavier and heavier. Finally they stopped. Erin grabbed a measuring tape and measured herself. When she say the results, she gasped. ZZZ Cups rested on her chest. They were huge. Erin looked at the strangely conveniently placed mirror on the wall. Her breasts, despite their enormous mass, stood at attention, sitting high on her chest. Her nipples were a light brown, her areola about an inch radius. Her nipples were tiny cones, pointing forwards. Her breasts were just little bit shorter than the length of leg between the thigh and the knee.
Then she felt a tremor run through her breasts. Grumblings could be heard from within, and Erin felt her breasts suddenly begin to get heavier. They continued to grow heavier, until slowly, but surely, they began to weigh her down. She ended up on her hands and knees. Erin felt her breasts wobble, and she heard a . . . . a slosh? As she tried to get up, but failed, she though about the transformation code she had input. It had included breast expansion, lactation.
