Right then, and there, she expands again.

Jane had barely enough time to get up before her breasts began to tingle, jiggle, then expand right in front of her. A yell escaped her mouth and the woman began to rub her breasts as they began to expand right before her.

"The...the the hell?" She could only stutter in shock while her already sizeable boobs became larger, rounder, and softer. They could've been cupped in one hand, but they soon spread even larger than that. Jane whimpered, wondering what was even happening to her at this moment. Her nipples peaked from the strange sensation, they too began to tingle with immense pleasure. Closing her eyes, the astronaut did her best to regain composure. The pleasure was too much and loud 'ooooh' escaped her mouth. Huffing breaths escaped her throat as the sensation diminished. She opened her eyes and gasped at what she saw. Her bosom had become big enough they were half the size of her head. They swayed with obvious weight that a subtle 'clap' could be heard as their meat slapped together.

Jane grabbed the nearest pipe to pull herself up, these were heavy. Strangely she knew they should've weighed heavier on her back. Still, it was extremely uncomfortable to try and raise her body, she gritted her teeth and put a arm underneath her chest. This helped immensely on taking away the weight on her spine.

"Steady Jane, steady." The astronaut tried to regain a semblance of control.
