Three to one

"What now?" the second said as both men sat there, balls full with the two girls.

"Now we need to get the third one," the first said as just at this moment a redhead got onto the bus. "Hey, come over," he called her and she couldn't stop coming over. "Strip, we need to dump some loads."

The girl got out of her clothes, looking worried at the huge cocks of the two men. The first pulled her over and onto his cock, the girl screaming as her pussy was visible stretched around his cock. Then another scream escaped her mouth as the second girl started fucking her asshole, making it gape.

Before too long the two men came, pumping load after load into the redhead. While she was still stuck on their cocks, the girl started to change. While her body morphed to resemble more Sarah, her lips got plumb and her face darker. As the guys pulled out of her, she was now a mix of the three girls.

"Hey, I know a nice bar nearby," the second said. "Want to join? We can take her there and show our work to the boys there."

"Great idea," the first said and they left the bus.

One stop later three teenagers, dressed in school uniforms got onto the bus. They were attending St. Mary's school for girls and even thinking of boys was strange to them. To their bad luck, some black guys entered the bus soon after them, noticing the girls with their backpacks and books.
