Swap his hands for her feet

Zack always wanted to know what it's like being a woman, or just having a woman's equipment. However, he could have never guessed to have this much power.

He stared at his sisters feet. Her socks were lying in front of the couch. Her toes were painted in a cute red. Zack couldn't take the tension anymore. Something told him this had to be real.

He didn't want anything to go wrong. He went over the 'REALITY ALTERATION' switch on the device, checking how easily it was to switch from 'on' to 'off'. He really didn't want anyone to notice anything weird, at least for now... the switch was surprisingly hard to flip.

According to the manual, he should simply hold down his thumb on the sensor atop of the device, think about the swap he wants to make, and then press the button on the underside of it. Quite convenient, he thought, especially compared to what he always would have imagined such a device to be.

One last time he chuckled to himself at how ridiculous this whole situation is. But he was determined to try.

"Alright... here goes nothing.", he mumbled under his breath, looking one last time as his sister's feet and then closing his eyes. He concentrated on the thought of his sister's feet being on top of his arm stumps instead of his hands. Surprisingly, he found it very easy to keep concentration on this exact thing despite his excitement, which he guessed was caused by the device to not accidentaly swap something unwanted - he read something like that in the manual.

After a short sigh, he pressed the button and opened his eyes. The process didn't take more than a second, if at all. He felt a faint tingle in both of his hands... feet. He looked over them. His sister's feet where his hands should be. The device being hold by two of his toes on this right foot-hand. He couldn't believe this was true. But it was too true to not believe... his member was highly erect.

He looked at his sister. She had his hands with his long fingers where her feet used to be. She was still asleep and didn't seem bothered at all.

He rushed into his room. Opening and closing the door with feet was an usual experience, however, it felt unusually natural. His regular feet would have had a harder time doing that - but his feet-hands somehow felt like he had more control over them, as he had over his hands.

He locked the door, put the device on his desk, and dropped into his bed, sitting on it.

"Unbelievable. But it's true. I... wow. I have nothing else to say.", Zack muttered to himself. He was shocked, but surprisingly calm. On the inside he was freaking out, positively though.

He wiggled his sister's dainty toes, and put the soles right onto his cheeks. He rubbed them all over his face, getting more and more aroused by the second. His heart was pounding quickly. The device was legit. He had possibilites. And right now, he had his sister's feet instead of his hands.

He looked at himself with his sister's feet in the mirror, mounted exactly on the other side of the room. He saw his shocked face with a gaping mouth and a pair of cute, small feet resting on his cheeks, like he was holding his face in shock.

He never had a real foot fetish, but found feet cute. However, now that this situation happened, he saw their massive appeal. He didn't waste any more time and sucked on the toes. It was ecstatic for him. If he would have sucked on his sister's feet while they were where they belong, he would just be disgusted. Now, however, while having her feet as his hands, he found this extremely arousing.

After a short session of sucking, he dried his salvia off his newly acquired feet on his bed sheets and began unzipping his pants, which was a challenge. However, he felt rewarded as he finally managed it and pulled his boxers down.

His boner was massive. Usually he would need some good stuff to get off to, but now, his predicament alone was the good stuff. He tried to give himself a footjob.

He felt ecstatic, the soles of his sister's feet rubbing against his cock, the toes playing with the tip... it didn't even take him 30 seconds to get off.

He took a few tissues and wiped off his cum from himself and his new cute feet. A very small part of him was absolutely disgusted by what he just did and by the fact that he actually likes this, but the greater part of him was too happy and filled with his newly acquired power. He would have a lot, a LOT of fun with this.
