Jen got the courage to ask Susan one more question. "Susan, could you tell me to stop eating my own shit, and that only you can use me like a toilet?"
"What? But you can't stop eating your own shit. Even if you glued your mouth shut, you would still rub your face in the shit. And if we couldn't use you as the toilet, then we wouldn't have anywhere to shit." Susan said, shocked at the request.
"Why can't I stop eating my crap? And what do you mean, we wouldn't have anywhere to shit? They could just use the bathrooms." Jen replied, confused.
"You have to eat your own shit because you read that it would make your breasts larger, or something, and you got so addicted that your body rejects anything else you put in it. As for why we can't just use the bathrooms, some messed up guy wanted to either get us to try your 'diet' or use you more, so he broke all the toilets, and you have been delighted to have so much shit since."
"But why don't huge lines form for me?" Jen asked
"Duh, after a week of waiting for their turn, people just started to shit wherever. You just roam the school, eating whatever shit you find." Susan explained, as though trying to get a kindergartener to learn that 1+1=2.
"You know what, Jen." Susan said after a moment of quiet. "I think you would be much happier if this was true. Yeah, you would. Ok. Picture this. Your pussy is on the end of a long, penis-like thingy that is aimed right at your mouth. That way, whenever you shit, you can just open your mouth!"
Jen groaned as her vagina stretched towards her face. Staring into her dripping folds, she feels poop sliding up the tube connecting her pussy to her crotch. She opened her mouth, and screamed in orgasm as mounds of scat fell into her open mouth. Some piss trickled down, to wash the crap down. Jen, lost to her poogasm, pulled her vagina closer, and started licking at it. Then she noticed that they had reached her stop and got out.
