It didn't take long for gravity to take effect on you again, and thankfully it led you to fall onto the softest position—Melanie's cleavage, right between both boobs. You worked to right yourself, squirming in the soft flesh—only to realize that, well, you were moving around in a spot more sensitive than the hairs on her leg. So if you weren't careful you'd be spotted by Melanie right then and there, and you didn't know how she'd feel about you hiding the ability to change size from her.

Better act quick!
