almost forgot the crucial part of the costume

During their walk, Quinn got used to her state of relative undress. Aside from the slight draft she felt and occasionally slipping on her stockings, this wasn't so bad. The sports bra, full-cut panties, and stockings were pretty comfortable, fitting snugly on her soft curves and toned thighs. Also, she had to admit that they were pretty cute on her too; the yellow and black stripes worked well on her.

Heck, she'd been eager for the chance to show herself off. It’d be a crime to let the body produced by those years of cheerleading remain hidden. Now she was wishing she isn’t have to hide her hair underneath the helmet.

The noises from the crowd echoed through the walls when they approached the doors to the field. The woman picked up some pom-poms "The object is so simple, even you can figure it out. Just take these pom-poms, shimmy up the opposing goal post and put one of them on each prong. Oh and sure to have the flag with you when do it."

"What flag?" asked Quinn as she held the pom-poms.

“Oh how could I forget." The woman took out a small yellow flag, pulled the back of the surprised Quinn's panties and pushed the pole downwards.

"EEEEK!" Quinn squealed and flushed pink at the uncomfortable felling between her butt cheeks. "Wait! What happens if I lose the flag!?"

"And that's it, good luck out there" She slapped Quinn's butt and pushed the confused cheerleader through the doors to the field, "you'll definitely need it." she said with a laugh.
