She noticed the spray bottle sprayed a lot of moisture into the air, but she noticed, with dread, that it sprayed down, and a very dark and deep wet stain was appearing in her lap covered skirt, and the moisture had seeped through the skirt into her panties, and dripped on her groin.
She quickly got up to wipe it away from a box of tissues in her room, but she doubled over in a brief feeling of abdominal pain. Like a sudden shift of her insides, and felt a crawly feeling as the pain subsided and tingling in her crotch began. She ran for the bathroom thinking something was wrong and she might mess her self, she gave up and set of to the bathroom as fast as she could, the feeling in her gut and crotch feeling to weird to run fast. Her panties, though wet, were beginning to feel tighter and tighter, and her groin began to feel really weird.
As she entered the bathroom, she was aware of a pushing feeling in her groin, as though it was morphing and pushing out into something, she no longer had can empty feeling there. And the crotch of her panties felt very full. Placing a hand on her growing bulge, she entered the bathroom and and looked toward the mirror.
