Thinking he might as well try the remote out on himself too, Mike decided to fuse himself with his older sister. First selecting Megan as the first target, then himself, Mike hit the Fuse button. There was a bright flash of white light, temporarily blinding Mike, then he found himself standing in his sister's room. The first thing Mike noticed was that Megan was nowhere to be seen. He then looked down at himself and figured out why.
"Holy crap, it worked!" Mike gasped, seeing a pair of breasts on his chest. He then covered his mouth. His voice sounded distinctly feminine, and somewhat like his older sister, although a bit lower. He imagined it was what he would sound like if he had been born a girl.
Letting the reality of the moment sink in for a second, Mike walked over to the mirror on his sister's closet door to get a look at himself. He was greeted with a rather interesting sight. The first thing he noticed was that his face looked like a combination of Megan's and his own, although it had a very feminine appearance. Judging from his appearance, Mike would have guessed he looked about 16 now, halfway in age between Megan and himself. His hair was about shoulder length, somewhere between the length of Megan's hair, which reached down to her waist, and his own short hair, a lighter shade of brown than his own, but darker than Megan's. His figure was more slender, but not quite as slender as Megan's had been. He still looked quite feminine, however, curves and all, but those curves were just ... less curvy than his sister had been by a little. Height-wise, he was now 5'6", halfway between his height and Megan's. He also had her C-cup breasts on his chest.

He was wearing her short denim skirt, and he could feel her bra and panties underneath his clothes. He also had on the Nirvana t-shirt he had been wearing, although it was now more form-fitting. He also had on his sneakers, but a few sizes smaller to fit his smaller feet. Additionally, his face was done up with makeup like Megan usually had hers, and his nails were painted a pale pink shade.
"This is so weird," David said to himself as he looked away from his reflection. Peering around the room, Mike began to notice that it looked different. It had a lot of Megan's stuff, but also a lot of his stuff. Curious, Mike went back to his room and saw that it was now a guest room. "Interesting..."
Mike wandered back to his new room and looked back at his reflection. There was still one thing he wasn't sure of. Was he a girl now? He had no idea what this device had done. There was one way to find out. Sticking a hand down his skirt and into his panties, Mike felt around to see what parts he had down there. It only took a second to discover that ...
