Sister v Sister

"Um, Rebecca, the reason the juice tastes strange is that I peed in it," said Chloe.

Rebecca started gagged. "Oh gross! Seriously!" she started dry heaving. She ran to the bathroom she shared with Chloe and started drinking water straight from the faucet. After that she rinsed with mouth wash. When she was finished, her phone dinged. She check the message: Piss in the toilet then swirl Chloe's toothbrush and hairbrush in the toilet.

Rebecca seemed to forget Chloe was being programmed by an unseen ****, and was mad at her sister for pissing in the orange juice and not telling her until after she drank it. Her bladder was full again and she pissed in the toilet. She then swirled Chloe's toothbrush and hairbrush in the toilet. When she was finished, she felt smug that she got **** on Chloe. She flushed the toilet.

Rebecca's phone dinged, but this time it was a message from Robbie, the boy she had gone out with last week on a first date that went really well. They were to go out again tomorrow. Rebecca gasped when she saw what Robbie was replying to. It was a text conversation she did not take part of:

My sister pissed in my mom's hairspray.

Really? That's gross!

It was so funny! Mom didn't know until after she went out with friends.

You think that's funny?

Yes. By the way, after dinner tomorrow night, would you like to fuck me up the ass?

Is this really you or is someone pranking me with your phone.

There was a photo of Rebecca, naked from the waist down. She had her back to a mirror and was looking over her shoulder and taking a selfie. It's me! I want your cock up my tight filthy bung hole!

Look this is too freaky. Maybe we should not see each other again.

Rebecca gasped. "Oh...my...god!" she said. She had no idea where that photo came from then she remembered the video of her pissing in her mom's hairspray.

"What the fuck is going on?!" she yelled.
