As she sees a pussy. When she looked up, she saw the UPS girl in her clothes, without the skirt and panties, looking aroused. Jen screamed, "Why are in my clothes!?"
"Dude, your in mine too!"
She looked down to see her in a brown shirt, black panties. the UPS girl put on Jen's panties and skirt, which fits her.
Both confused, Jen said, "What happened?"
"I don't know, I just remembered both of us having a urge to have sex, so I kiss, while taking off your panties, and licking your pussy. Then you had a orgasm, and this happened."
"Wait, a kid named Kyle Perkins transformed or dared me to change realities when I get an orgasm by a girl, and the first girl I see will start it," said Jen.
"So, in this reality, we switch bodies," said the UPS girl.
"No, or else we would look like each other. I think we switched our life roles," said Jen.
"What?"
"Like, you were an UPS delivery girl, which is what I'm in your clothes, and I was a cheer leader, and your in my clothes," said Jen.
"Oh, well my name is Katie."
"And I'm Jen, bow let's have revenge on that bastard."
