So, Sarah made up her mind, the feelings of her new body were incredible, but she didn't want to sacrifice her beautiful old body and life for anything, even the best sex she could ever experience. Sarah decided she'd try to stay out of Jon's way like he demanded and hope that Jon will be true to his word that he'd change her back later. Sarah considered asking Biff to help, but she loved him too much to see him get hurt, and there isn't much he could do to someone like Jon who can swap bodies so easily.
However, that didn't mean that Sarah couldn't enjoy her current body as long as she could. It was really the best way to get revenge on Jon, if he was going to force this dog girl form on her, she was going to make damned sure it was pretty near totalled by the time he got it back. From what Sarah could tell from her earlier sexing with Biff, Jon was a virgin, with any luck and a bit of help from Biff, she could pretty much make sure that he was as lose as a street whore by the time he got his body back.
Sarah reasoned that there was really not much time to waste, he'd probably get bored of her body and give it back to her in a few hours, which meant she had to get started. But there was something else nagging in her mind, what if Jon wasn't going to give her body back? She was going to be stuck like this forever. Sarah thought about it and decided to go through with her plan anyway, whether she was going to be stuck like this forever or for a day, the sex with Biff was the best part regardless of the outcome in the end. And if she really was consigned to this fate, she would be making sure she'd fuck Biff more often anyway so it made no real difference to her.
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, with a bit of care, she gently walked over to Biff, he was still lying there, playing with himself a bit.
"Biff, help me", she asked, "I want to go again"
Biff looked at Sarah with a very perplexed expression on his face, Sarah was really asking for more? What had gotten into her?
"Sarah, what are you doing?" Biff asked.
Sarah trotted over to Biff, leaning face to face with him, she planted a strong kiss against his surprised lips before replying, "Think of it as your birthday", she said, before kissing him again.
Biff stuttered, "But my birthday is months away", he replied.
What am I doing? Biff asked himself, Why am I fighting this?
Biff wrapped his hands around Sarah pulling her close, she squealed as her naked breasts brushed against the hair on his chest. Pushing her legs aside, Biff gave Sarah a bear hug as he drove his tongue back into her mouth. Sarah responded with all the fire and passion that seemed so out of character for her, but Biff was losing his reasoning as his little fellow downstairs went back to Red Alert.
"Happy birthday", Sarah said, between kisses as Biff started to stroke her breasts.
