"Well," Jenny said, shaping the idea just had flashed and aros in her mind. "what if I were your hand?"
"My... hand? It is completely different from my expecting. So, why my hand? I mean, there are planty of parts of mine you can possibly be..."
"I think being the most used part would be better." She replied.
Jeff started to enter some options to Chronivac and asked her for how she want the change be, and Jenny said "I want to maintain my own body, only with some core differences."
"I'm not sure if I'm understanding correctly, explain me more."
"I want to have own head, arms and legs as a hand. I will replace your right hand (as Jeff is right handed,) and my head and limbs will act as your fingers. I'll accept some minor changes, and I can still move by my own when you are not moving your hand, me, consciously."
"That's pretty specific."
Jeff soon finished entering the requirements to Chronivac.
"I set timer to half a year." Jeff told her, "but we can change us back anytime we want... The timer just means it will automatically end that time." He submitted the change, and it started right after.
Jenny was naked from some time mischievously put her back to Jeff's hand. They immediatley connected and his hand was sinking into her flesh, linking his arm to her spine. At the same time, Jenny was shirinking to the size smaller than 8 inches. To be proper "finger"s, her neck was extened bit and legs were reversed where they facing, to heels of her legs facing the same side with her belly(or palm, for Jeff) With bit flattened breasts and vagina placed on palm, Jenny was literaly the right hand of Jeff.
"This is... insane! How Ismall and how CLOSE to you I am!" Jenny yelled in exotic place of her. She move her limb and neck, Jeff's finnger. The way those connected on her body was weired, but also it was facinating at the same time.
It was also the same for Jeff. Unlike Jenny can only feel her body on Jeff's wrist, he could feel his "hand". His "middle finger" was speaking herself, maving all the fingers freely, and even two of his "finger"s had their own fingers! And the most odd thing was having his girfriend's vagina on his palm, which was somewhat kinky.
"It's truely insane!" Jeff also said to Jenny.
"And so... what would we do for now? Do you have any good idea?"
