Extend the Story - Add a Room

She decided enough is enough and got out of bed. She stood up and almost fell over from the new weight but kept her balance. She continuously blushed and started to slowly walk to the doorway. She tried opening the door but found it to be locked. She sighed and decided to try out the bathroom for an exit. She went over to the doorway and went through.
Except that her new breasts got stuck in the door, causing her to not be able to walk in. She backed up a bit and tried walking in a little faster. She got through the door this time but caused her to trip and fall. She braced for impact but was protected by her breasts. She found it odd and got up, her boobs being a bit more jiggly than usual. She looked at herself in the mirror and sat that the cool lumps on her chest were caused by the slime.

The slime likes the attention and grows.
