So, Sarah made up her mind, she wants to stay this way. Well not exactly this way, she wants her old body back, but still wants the amazing sex. Now she wasn't sure Jon could or WOULD do that for her, but she was damned well going to ask him. At the very least she was going to see if she could stay in his body longer. Obviously that was not going to work as Jon was probably as sick of Sarah's body as she originally was of his, but if he stays up to his earlier threat, even a 5 minute conversation would guarantee her a good 5 days of amazing sex with Biff.
Sarah really didn't know what it was that caused her to feel this great about sex, but she'll find out soon enough. Sarah rolled over on her bed and got up on all fours, jumping down to the floor she looked back up at Biff who was still lying there, playing with himself a bit.
"Biff, help me", she asked, "I wanna get changed and go find someone"
Biff sighed, this was really the only downside to a girlfriend like Sarah, he had to help her wash herself and get dressed, but hey, he got to see her naked and fiddle with her bits in the bath so it wasn't all bad. Sometimes they'd make out in the bathroom and that was pretty arousing in and of itself.
Sarah went and washed herself first, she didn't want to "tip off Jon" that she'd been enjoying his body a bit too much while they were swapped, after making sure Biff cleaned out her pussy nice and properly as well as washing and combing the fur on her legs, Sarah trotted back out to her bedroom so she could pick out some clothes to get changed into.
Sarah was feeling unusually sensual now, but she really didn't want to end up flashing her panties to everyone who walked behind her so a skirt was out of the picture, so were long pants, they'd just drag on the ground with her new shorter legs. She knew that nothing would fit her quite right since they weren't the right size for her body, but she figured she may as well look reasonable. So with a bit of help from Biff, she got changed into a clean pair of panties and a clean bra, then slipped on the tightest pair of shorts she could find and button up blouse that Biff kindly did up for her.
She kissed Biff goodbye and went off to find Jon and Karyn.
The two of them were at the mall, Jon in Sarah's body and Karyn were laughing at some joke or another they had exchanged when Sarah turned up at their table. Karyn sighed and leaned back in her food court standard issue chair while Jon turned to meet Sarah face on.
"Sarah, what did I tell you earlier?" Jon asked, "Buzz off or you wont get this body back!", he said, provocatively running her own hand down her former body's curves, as if he were showcasing it to her for the first time.
Sarah jumped up on the chair next to Jon and sat down, of all things, "No, no, no, and no. Five minutes is all I want", she said.
Jon sighed, "Ok, you've got 5 minutes", he replied, turning back to take a bite out of the subway sandwich in his hand.
Sarah scowled for a moment, she only ever ate salads and Jon was here eating junk food, but she disregarded that because she really needed to be polite to Jon right now.
"Jon, I've been thinking about it, and I really want to say that I'm sorry for everything I did", Sarah started.
Jon grunted, "Go away, begging for mercy wont get your body back", taking another bite.
"No, you misunderstand", Sarah said, "I, had an experience earlier and it proved to me that this swap was amazing. I honestly thing that I was wrong in teasing you for this amazing body you had"
Jon looked at Sarah confused, "Really? What kind of experience did you have that made you leap to that conclusion?"
Karyn chuckled, "You fucked Biff, didn't you?" she said.
Jon nearly choked on his sub, that was his sister's body and Sarah was fucking a stranger with it, "WHAT?" he demanded.
Sarah looked indignant, "Hey, you're the one who gave me this body! You're upset that I use it the way I use my old one?"
"Yes, but " Jon trailed off, giving a quizzical look to Karyn.
She shrugged, "You're the one who did it, not me", she said.
"Ok, well what do you want then Sarah?" Jon asked, "Cut to the chase, I'm busy here"
Sarah spoke very carefully, so she wouldn't get mistaken, "I want you body"
"My body?"
"Yes"
"Well you can't have it!" Jon said
"Jon, come on, you went through high school as a freak like this, everyone teased you, then you fobbed your freakish body off to me in exchange for my smokin' one, no one thinks it's strange for me to be like this and I've had the best sex of my life all morning. I don't want to stop feeling like this, and I WANT your body!" she said persistently.
"Well you can't have it", Jon replied, "I want it back", finishing off his sandwich.
"Well I'm going to keep it one way or the other, and there's not much you can do about it", Sarah replied.
"Are you kidding? I'm the one that made the swap, I can undo it in a flash", Jon said
"Prove it"
"Ok I will"
Jon stood up from his chair and looked at Sarah, very carefully; he got down on all fours and chanted, "You can have it back. You can have it back. You can have it back"
His three swaps, for Sarah's bra, panties and body were all reversed in an instant. Jon was now again wearing his sisters and dog's body from the neck down while Sarah was back to her old self. Sarah looked herself over and patted herself down; she really was back to normal. But she felt different still, not the same as she did after she and Biff fucked in Jon's body.
Jon was on all fours, looking up at Sarah, "So, you still want to have my body, or are you just using this as an excuse to run off?" he said.
