It was Susan who had followed Jen after she had run out of the bus. Jen could feel Susan's warm touch of her hand against her now furry legs, but also a rising warmth at the end of her two centaur bodies.
"Why did you stop running? We aren't there yet?" Susan looked up at Jen with some concern. It then dawned on Jen that in this reality she is too big to be in any buses, so she had to run outside next to the bus. "Err... I had to take a break." Jen tried to do signal with her arms, but were left with just wiggling her nude human body on top of the enormous horses which were now the rest of her body.

Tears started falling down from her cheeks and blurring her vision, but she can't even reach her face anymore as she has no arms or hands.
Susan turned around and frowns at Jen. "I know you really want to mate with other mutants like you, but it has to wait until we meet your family." Jen stared back at Susan with two erect cocks filling her mind with lust. She felt disgusted by herself, but there was nothing she could do. Nothing other than...
