Observe your sister

Your sister sets her now empty mug on the coffee table. She turns on her camera on her phone, and stands it against the mug. so that the lens is facing her. She presses the record button and gets back on the couch, sitting on it backwards so that her (admittedly nice) ass is facing the camera. You watch on, intrigued at what she's doing.

she shakes her ass a bit, her fat cheeks clapping as she bounces. She stops, and slaps both cheeks with her hands, and then spreads them wide. She turns her head so that the camera can see her smile, then it happens. Her asshole opens up and the tip of a brown shit pokes out. She slowly pushes as a massive log out of her ass, letting it slide out and plop onto the floor.

your pussy gets instantly wet at the sight of it, you've never seen someone else shit in real life infront of me before, it was unbelievably hot. You clamp your thighs together, trying to calm your loins while your sister turns around and picks up her phone, tapping away at it again. "this is gonna make a good tiktok. Wonder what everyone will think of that massive shit I just took, haha."

Your sister brings her right hand down to her pussy, gently fingering herself while she posts the video with her left hand. Your sister has never masturbated openly infront of you before, and you don't remember the voice in your dreams mentioning this, so you chalk it up to being a quirk of this world. After all, if people piss and shit openly when they don't really have to, why wouldn't they also masturbate openly as well?

"Oh hey take a look at this!" your sister shoves her phone in your face. You look at the video playing on it, showing a classroom full of students. One of the boys sitting in the backrow is the subject of the video, as the camera focuses on his rock hard cock as he jacks it off a few times. It's incredibly sexy, and you can't help but rub your clit as you watch on.

The boy stops jerking, takes a second and aims his cock. A stream of piss shoots out of his dick, arcing high into the air, and landing on the floor clear across the room, and impressive forceful stream. All the other students, boys and girls, start cheering and clapping when he makes it across. "Jason has such a firehose of a pisser," Your sister says, "It's so hot, I would love to fuck him some day."

She gets up and goes to her room as well. You glance down at the pile of shit your sister just laid, and to your astonishment it's disappeared. You also notice that your mom's piss puddle is gone as well. Seems the part about it evaporating away was true as well. The endless horny possibilities of your new reality run through your head...
