Humiliate her in front of the whole camp

As she walks towards the Dining Pavilion she can see people staring at her as she tosses out empty greetings towards some of the cuter boys. Internally, her mind races, trying to decide the perfect way to humiliate that bitch McLean and teach her where she belongs. She finally decides on a plan and begins walking towards a group of demigods from the Ares cabin.

"Hey hon, I need you hunks to do me a favor," she simpers, laying a hand on one of the demigod's chest.

They look at each other before nodding.

"Uh yeah, of course, we can help you out with anything," one of them says, leering at her.

She explains the plan to them and hopes that they remembered most of it, as children of Ares weren't exactly known for their brains.

Drew sighs to herself before strutting into the pavilion with a posse of Ares demigods following her. By then most of the campers had already finished with the burnt offerings.

"Excuse me, everyone!" She calls out to the dining pavilion, "Quiet down!"

Immediately, people turned their attention to her and she spots Piper at the Aphrodite table talking with Lacy or something. One of the Ares campers brings her a chair as she daintily rests on it, setting the Rulebook down on the ground beside the chair.

"Piper McLean, hon, I need you to come up here."

Piper slowly walks up to her almost in a trance before standing near her.

"Campers, it has been brought to my attention that one of my cabin members has been quite naughty, so I would like to have them make it up to everyone here for their actions."

Drew waves Piper over, "Come on dear, bend over my lap."

Piper drapes herself over Drew's lap, wriggling around a bit trying to get comfortable. Drew gropes Piper's bubble butt briefly before pulling down her shorts, revealing a pink thong. Piper begins to struggle, forcing Drew to put more power into her charmspeak.

"Stay Still," Drew orders as Piper stops struggling.

She slides her fingers under the waistband of Piper's thong, pulling upwards before yanking it down.

"Now I want you to count every time I spank you."

Drew swings her hand down onto Piper's fat asscheek, causing it to jiggle as Piper gasps out "One!"

"Two!"

"Three!"

Soon Drew began to feel her arm tiring from all the spanking she delivered to Piper. Piper was sobbing as her ass glowed bright red from countless marks, her pussy was dripping wet, coating her thighs. She motions to one of the Ares campers and they grab Piper by the shoulders, forcing her to stand on unsteady legs.

"You know, I think that punishment wasn't enough, I think she enjoyed it!" Drew calls out to the rest of the pavilion as her posse forces Piper's legs open, exposing her gushing cunt to the rest of the campers.

The campers begin to call out and jeer as one of the Ares demigods hands a black marker to Drew.

Drew calls out to the rest of the pavilion, "to make up for my cabin member's slutty behaviors, I'll designate Piper as the camp's free use slut until I say so!"

The crowd behind her explodes in excitement cheering as Drew uncapped the marker, writing "Free Use" on Piper's forehead and "Property of Camp Halfblood" on her chest.

She caps the marker and shoves it halfway up Piper's asshole before stepping back and nodding.

"One more thing before all you dears start lining up," Drew addresses the crowd once again.

She makes a fist and slowly pushes it up Piper's pussy before pumping it in and out in quick bursts causing Piper to shake and squirt as her eyes roll back into her head. Her tongue lolls out as a bead of drool drips down. Drew steps back to admire the obscene state Piper was in before shaking her hand clean of Piper's juices and waving the crowd on. The Ares campers hauls Piper to a table before lining up themselves.

Drew gives her wet hand a small taste, "Hm, not bad for slut like McLean"
