Jeff wasn't entirely sure where he was at first. Well, other than between some girl's legs, of course, but other than that, no idea. (He also had no idea that without a time set to return he would be attached to the body part till the owner dies)
Given how dark it was, he at first thought he was blind, but as his 'eyes' adjusted and the girl he was attached to started moving around, he simply realized that his view was obstructed by the girl's panties. He realized this might not be as fun as he first thought. Especially when he heard the girl's voice, loud enough to hear but slightly muffled due to his current position.
"Yeah, don't worry, I'll be at practice today. I can just have that geek finish the project for me. ...Of course she will! I've got her wrapped around my little finger."
Jeff recognized the voice as Penny Young, one of the cheerleaders at his school. She was a smoking hot redhead with a pretty face, B-cup breasts, and an ass perfectly made to entice the boys during a game. This helped quite a few people overlook the fact that she was a complete and utter bitch to anyone she saw as beneath her. One of those people being Jeff's sister Emma, who just so happened to be the 'geek' Penny was talking about. They were currently working on some kind of history project together, and while Jeff didn't know the details of it, his sister's complaining was more than enough to give him an idea of just how little Penny was pulling her weight. And he was stuck forever as this girl's vagina, listening to her trash-talk his sister! It was infuriating, and he felt his new 'lips' tightening in rage.
Jeff suddenly felt the legs around him pushing themselves together, and Penny said, "I'll talk to you later, Claire. I need to finish getting ready." He then heard her hang up and mutter to herself, "But first, bathroom..."
Uh oh. Was that what that tightening meant? Now that he thought about it, Jeff could feel a dull pressure slightly behind and above him. That must mean Penny had to pee. Admittedly, Jeff hadn't thought about the fact that he would probably have to deal with that as a vagina. He mentally kicked himself for being such an idiot. And did so again when Penny pulled her panties down and he saw the toilet bowl.
His vision swirled as Penny turned around and sat down on the toilet, ready to pee. He tensed up and prepared for the inevitable. "Oh God, please no. I don't even want to know what Penny's pee tastes like," he thought to himself, too freaked out to question whether he even could taste anything anymore. He waited for the flow to start...
It started as a trickle at first but eventually became an even flow to a gush of urine, it was salty and hot tasting. Jeff felt like he was puking. "Please make it stop!" Jeff pleaded to his mistress, (who was totally unaware Jeff was her vagina). As the flow started to subside to a trickle finally finishing Jeff wondered what he had got himself into. Jeff felt as Penny dabbed Jeff with toliet paper.
"Whew!" Jeff heard Penny say. "I really had to go."
Jeff (as a boy) thinking this was going to be a excitingly experience. Found it being humiliating. And on top of that, of all the girls, he had to be the soul vagina of a total bitch who was mean to his sister. Mentally Jeff cried tears no one would ever hear. (Not even Penny).
Penny got up from the toilet, pulled up her panties got her cheerleader uniform on. Checking herself in the mirror and said.
"Now to cheerleading practice".
