Before Isabel can do anything, Heather grabs her bra/boyshorts from behind...

(chapter originally by hanskumoekk at writing.com)

Isabel does get back up to her feet as told, but right when she was standing up, Heather sneaks up quietly behind Isabel. She grabs a large chunk of Isabel's bra and a large chunk of Isabel panties as she pulls Isabel towards herself by the back of her underwear.

"Finish this race, or else......." Heather whispers into Isabel's ear while clutching hard on the waistband of her shorts and her sports bra, making it clear what will go next if she doesn't.

Isabel closes her eyes and bites her lip while holding her arms tight over her bra and crotch of her panties when Heather clutches them and pulls her by them, terrified that she might just expose something right there.

But Heather lets go of her underwear and backs off, sure that she has made the message clear for Isabel.

What will Isabel do now?
