Yolanda suddenly got a very shocked expression on her face "Uhm, why don't you sit down on the couch? I have to take a shit soooo bad!"
She then reached back and grabbed her ass, trying to keep the shit back in. "That taco bell made my stomach go bad, but just wait there, I'll be back in about...." she paused to look at her watch... "45 minutes"
As she walked away, you eyes were glued to the massive ass barely covered by her tight spandex booty shorts, that ran straight up her crack, looking closely, you could clearly see a massive brown stain on them since the incident in the car.
She was wearing this tight tank-top barely containing her massive chest, with her nipples pointing out from between the seams.
Once she was gone, the time went. You could clearly smell that she was taking a crap upstairs. Even though it was on the top floor, the smell almost made you gag. the smell was unbearable, and it got even stronger.
You could litteraly hear her spew liquid crap into the toilet, followed by some chunks and dhiarrea. And then it spewed some more followed by some air bubbles, splattering the shit everywhere.
The sound and smell together, was too much for you, and finally, you fainted....
~~44 minutes later~~
You woke up with the sound of a toilet flushing.
"Oh, finally she's done" you thought in relief.
But as you came to your senses, you noticed something was wrong... Everything was HUGE, no wait... You've just shrunk...
"What the fuck is this shit?" you yelled out.
You knew you were still on the couch, looking where you stood, you noticed something slimy, sticky, and brown.
"Wait a minute...." you said thoughtfull "This is a shitstain from Yolanda, this must be her seat... You tried to move, but every slight movement made you slip and fall head first into the thick layer of shit.
But suddenly you heard a massive booming sound. It was Yolanda, she was done in the bathroom.
"Hey, isn't it typical that there isn't any toilet paper left?... just my luck" Yolanda said with a slight playful giggle.
The booming came closer, and so did she. She moved towards the couch, and stood in front of it.
"Oh... my... FUCKING.... GOD!" you yelled. As she stood right in front of you, you could still see the shit stained booty shorts, digging so deep into her crack that you don't even know where it ends.
But then that ass seemed to grow bigger, and bigger, and bigger.... No wait.. She was sitting down, on you!
In shock, you tried to run away, but the layer of shit below you made you slide to the back of the couch, and Yolanda JUST barely missed you.
"Phew" you said as you wiped your forehead, but you wondered how lucky you really were.
The impact her ass did on the couch made her shorts slide down, so relieved to be free, her cheeks exploded out from them, expanding to twice it's size, she leaned forward to eat some old beans on the couch table, her cheeks parted and you could see how the inner walls of her cheeks were dripping fresh liquid shit, you know she's black, but you've never seen a darker crack, there was litteraly a small puddle of liquid shit floating on her shorts.
She arches her back, and her asshole is looking right at you!, suddenly.....
