I have really been wanting to hear a story about a cheerleading squad ganging up on their cheer captain and maybe the co captains for something she/they have been doing that has pissed off the rest of the squad. After plotting their plan, they tie and gag her/them in a vulnerable way then begin to torture them by stripping them humiliating them and punishing them in various ways (intimate ways would be nice) and making her/them do humiliating and degrading things to the main conspirators or possibly the other captains. Finally, the cheer squad would leave them tied up and gagged scarcely clothed or naked in a public place where she/they would be humiliated at the sight of the rest of the school or even tied up in the football teams locker room to be played with. A different group could be a group of friends with a snotty friend or even two rival schools that bet the submission of their squad over to the winning team's cheerleaders. This could be an amazing story.
I provided a lot of details so feel free to pick and choose the best if interested in writing a story
Good hunting
