You're blinded by light, which hurts your eyes, but your nose rejoices at the sudden flow of fresh air. When your eyes finally clear, you are startled to see Beenish's face take up your full field of vision.
"So, did you-BUUUUURRRPPP! Oh, sorry about that, did you have fun down there?" You're stomach control is tested once again as it screams at you to vomit from all the terrible smells that are coming out of this girl's mouth. You think better of it to piss her off though, so you bolster yourself and just nod.
She smiles broadly, and you can almost see her nautious smelling breath seeping through her teeth. "I thought you would, and I'm sure you'll get to have more fun down there later..." You shudder at the thought. "But right now I need to go to the bathroom. You don't mind, right?" Before you can say you want to be somewhere else though, you hear a small tinkle below you, followed by a much louder cascade of what can only be piss.
You look up at this girl in horror, but she totally misreads your expression. "Oh, does this turn you on? Little pervert... But oh well, it's kinda cute. But now comes the really... releaving part." You see her face scrunch up in consintration, before your hear, and soon later smell, a hugely booming fart.
Her face relaxes for a moment, before she giggles, smiling her toothy grin at you again. "Did that turn you on too, hun? Well I hope so, 'cause otherwise this next bit is going to be absolutely disgusting... My mom always told me not to eat mexican food because it was evil, but I fell in love with the tastes in spite of her. Though... I get what she was saying about it being evil, every time I have the absolute WORST diahrea..."
In spite of yourself, in a sort of morbid curiousity, you look over the edge of her hand down between her legs to the water below. You can't help but feel sorry for the toilet... Beenish's hand sort of tense arouond you, and you hear yet another fart, but this one is different. Much wetter and longer than the first, you can hear the wet slapping from her ass, before the smell seems to attack you, the methane envoloping your body and making you unable to breath.
"Oh man, here comes the big wave..." You look up from the edge of her hand to see her with a massivly strained expression. Your last thought is that this is going to be absolutely disgusting, before the smell and the involuntary will to vomit overcomes you, making you lightheaded before...
Choice 1: You fall off of her hand and between her legs, splashing into the toilet right before Beenish releases the "big wave", too late for her to stop it...
Choice 2: You pass out, only to wake up with her frowning at you, thinking you're sick for getting so turned on about her having diahrea that you would pass out, and that she should cure you of your sick side.
