Tight elastic and synthetic fibers

Due to the type of panties Sarah was wearing, which was made with tight elastic and synthetic fiber, none of the cum had fallen out or leaked through, at most , the outside crotch was slightly damp. Sarah ran from the bus towards the school, feeling the hot slick mess of cum move around her panties, not only coating the outside of her pussy but also stimulating her as she moved causing her clit and nipples to become hard and sensitive. With every step she tried to hurry to school so she could empty the cum out into the toilet, every step worrying if any of the cum might work its way inside her .
