After she had confirmed that Jon had his eyes closed Karen got on to the part of the spell she wasn't all to keen on. According to the book she had to lick the parts of each body that were to be swapped. Thats why she wanted Jon a little cleaner than usual, also why she didn't want to swap groins that would require giving Jon a blow job. After looking up and down the peaceful Jon she decided on what to take. She sat down and started to run her tongue up and down her legs. She wanted to see what it was like to be a bit taller and stronger and by taking Jon's semi athletic legs she could do that. She was suprised at how her tongue never seemed to go dry as she coated her legs with a light layer of saliva. Next she started to work on Jon.
"DON'T OPEN YOUR EYES!!!!" She said forcefully as she saw him start to peek with curiosity. She knew he could feel her licking him but it was awkward enough without him watching her. After she was done she knew there was only one thing left and that was having the parts touched. Then she got another idea as she was climbing over him to touch their legs. She made sure his eyes were closed and she lowered her top and licked her nipples making them erect then licking both of Jon's. Then she touched them perfectly on Jon's and layed her legs on his. What happened next was hard to define, she felt really warm then all of the sudden extremely cold. Soon she felt normal again and figured the transformation was done.
"I think its done." She said as she backed up and found that she hit the ground a lot sooner than she was expecting. She then looked down and saw that her smooth legs were now hairy and more toned. She even had the tan that Jon had gotten from the pool yesterday ending where his trunks had ended. "This is defiantly different." She thought as she felt her new legs. She looked at Jon and saw her nice tan legs going on his body fitting somewhat awkwardly since they didn't meet the butt that they were meant to.
As Jon opened his eyes he saw that Karen was feeling up her legs, her hairy legs. He then put two and two together and saw that that was what she switched. He then started to run his hand up and down his leg feeling the smoothness of it and then swung his legs over the side of the couch seeing that they weren't as long as they used to be. "Well this is why were you licking me?" Jon asked.
"Ya that is what the spell told me to do" Karen blushed. "I just wanted to see what it was like to be taller."
"This is pretty cool actually but what did you lick my nipples for?" Jon said as he saw that they were different, bigger.
"Because smart guy," Karen said as she tweaked his nipples, "I wanted to try something odd." She said as Jon saw that they were now standing at attention poking out much farther than normal.
"Wait so I have your nipples, girl nipples." Jon stated.
"Ya sure do Isn't it great now you get to deal with the fun those bring you and i get the plain boys." She said as she dropped her top to show him the now smaller looking nipples on her breasts.
"And remember Jon for the next 24 hours we can still swap anything." She said licking her pinkie finger then taking Jon's and doing the same. Finally she touched them and they watched as they slowly morphed into each other giving jon a smaller finger with a long nail and Karen a finger as long as her index. "Just like that."
