As Karyn stood, Jon became aware of a sensation of pressure just behind his face. It was almost like a sinus headache, but strangely different. Karyn seemed to feel it too; Jon felt her hand rest on his forehead, and then she squeezed her legs together around him. Sitting at her desk, she had lost track of how long it had been since she had gone to the bathroom, but now that she was standing, the sudden urge could not be ignored. Jon was roughly shifted between her tightly-closed thighs as she dashed toward the bathroom.
Jon was dazzled by the brightness of the room as the red panties were suddenly yanked down from his face. He had but a moment to take in his surroundings, but it was just long enough to understand that he wasn't in her bedroom anymore. Directly beneath him was Karyn's toilet. It rushed up at him and all went dark once more.
Never had Jon suffered any delusions about women's bodies being all flowers and rainbows. He was well aware of all the functions a pussy served. People tend to pee quite a bit more frequently than they have sex, and now that he was the organ Karyn peed from, this was bound to be his primary role. Jon hadn't failed to consider this when he made the wish; on the contrary, being used in this way was a major part of his fantasy! Even if he was too ashamed to admit it even to himself, this was something he'd been looking forward to. But now that it was really happening and there was nothing he could do about it, he was beginning to have doubts. Would he taste it? Jon had never actually tasted pee before. He would daydream about it and even jerk off to thoughts of it, but he had never been able to bring himself to actually try it.
Now that Karyn was seated on the toilet, though, it was far too late to change his mind. Jon had no idea what had become of the wishing stone, and even if it were in his grasp again, he wasn't sure what wish he could make that would undo the effects of this one before it was due to expire. Now he was going to put up with a month of this, a whole month, and he had only just begun to experience the full ramifications of his wish. Why hadn't he started by wishing to spend a merely day as her pussy, or even just a few hours?
His thoughts were rudely interrupted as Karyn relaxed her bladder and let the gates burst open. The sensation was almost indescribably strange to Jon, like a runny nose, but turned up to the intensity of a broken fire hydrant. Hot piss poured in a torrent from Jon's face, hissing loudly as it landed in the bowl. The acrid smell of Karyn's urine wasn't actually as bad as Jon had expected. It certainly wasn't pleasant, that much was certain, but it wasn't unbearable either. What surprised him, though, was the way it went absolutely everywhere. The way Jon had always imagined it, Karyn's pee emerged in a solid stream like a guy's. In reality, it came out as a spray, clinging to his lips and dribbling in little rivulets across his cheeks down to her buttocks. No wonder women wipe when they pee, Jon thought.
It seemed like at least a minute before the flow came to an end. Karyn must have really had to go. Jon waited, expecting at any moment for a hand to appear and wipe his damp face clean with some dry tissue. But instead he was greeted with an awful sound.
Jon and Karyn were a typically intimate couple, but there are limits to intimacy that some people refuse to cross. Karyn would never have dare to pass gas in Jon's presence. In fact, she never used his bathroom to do anything other than pee when she came over to visit. But now she was in the privacy of her own bathroom, and as far as she was knew, her vagina was no more conscious than it had ever been, so she had no shame in farting now.
The odor was repulsive. Jon hadn't fantasized about this part at all. It simply hadn't occurred to him that, down between her legs, he'd be subjected to all the outbursts of that other orifice just behind him. Now it seemed quite obvious in hindsight, but that didn't make him any less disgusted. Things got worse for Jon as he felt the pressure of Karyn beginning to clench, hard. A dark mass -- he couldn't quite make it out in the darkness, though of course he knew exactly what it was -- appeared to emerge from just behind him and hang at the bottom of his field of view for a few seconds before breaking off and dropping into the bowl. A splash of cold water splattered across Jon's face. He felt like gagging. Karyn continued to bear down, and more excrement came out, much to Jon's displeasure. The smell trapped inside the toilet bowl grew ever more nauseating with no end in sight.
After what seemed like hours, Karyn finally lifted her posterior, wiping herself clean. As she stood up, Jon was relieved to be dry again and no longer stuck staring down at her turds. He had been so anxious to get out of Karyn's panties before, but as she pulled them back up, it was like curling up in a warm blanket. The soft smell of her sex was like sweet perfume compared to the hell he had just escaped from.
This whole experience was far more than Jon had bargained for. And now he had to endure it over and over again, possibly every day, for a month? He would certainly go insane.
