Clancy was surprised at how early she woke up this morning, and knew it would be a while before anyone else in the family also woke up. There wasn't any work or school today, though, so she could take it easy. She crept out of bed without awaking her husband, and went to the bathroom in her nightie.
When she did, though, Clancy noticed on the sink that there was an unfamiliar box with a button on it and instructions to push it in a space of 6 feet. The bathroom had just about that much space open, so she did just that in the middle of it and it began to expand. Clancy shifted the box around as it expanded so as to not cause any damage, and soon enough the bathroom was full with a wardrobe, and she had to step into the empty bath to get to the doors. She couldn't open the doors all the way but she saw many different types of clothes, and writing inside one of the doors explaining how it worked.
Clancy shrugged it off and assumed she was still dreaming, and grabbed something at random - a men's jock strap, the thought of which amused her. She pulled her panties down and pulled the jock strap up, and just like the door said, she grew a penis and balls, which amused her. She could see a button on top of the wardrobe and pressed it, compressing the wardrobe back into a small box. She then stepped over to the toilet and used her new equipment to empty her bladder, something she'd never experienced before. She still felt a bit tired, though, but when she was done she just stretched with her new junk hanging out knowing that she'd wake up soon.
A moment passed and realization began to dawn on her that she was awake and all that really happened, and it was enough to fully wake her up! Trying not to alert anyone but being quick, she put her new genitalia back in, grabbed the box and her panties and went downstairs. The living room had a bit more space, so she activated the wardrobe there and opened it up. Eventually, in the seemingly infinite selection, she found a pair of women's panties and threw the jock strap off and put them on, sighing in relief when she had a vagina again. Though now she was back to normal, she thought more of the possibilities...
