Give it up already!

"Give up already, Jamie!"

"No, Ben!" his sister, Jamie, struggled against his growing control over her body, "I wouldn't have gone along with your stupid bet, if I thought you'd actually be able to possess me!"

"I won that bet fair and square," Ben huffed, "Your body is mine for the week."

Jamie's heart pounded as her brother's words echoed in her head. She desperately searched for a way to regain control of her own body. She clenched her fists, refusing to let Ben enjoy his victory.

But she could feel him gaining control over her muscles, slowly but surely, wrapping himself around her fibers, tightening its grip with each passing moment. Jamie's breathing became shallow as panic started to set in.

"I won't let you do this, Ben," she whispered through gritted teeth.

Ben managed to lift her arm and pointed it directly at the mirror in her bedroom. Jamie watched helplessly as her own hand pressed against the glass, leaving smudges in its wake. A sinister grin spread across their face as he reveled in his newfound power.

"Hey..." Ben uttered, straining her vocal chords into a chilling blend of his own tone and Jamie's, "Look at me! I'm you, Jamie!"

Jamie was taken aback. And Ben seized the moment to complete his possession.

Jamie's world became a haze of blurred images and muffled sounds. She felt like a ghost trapped within her own flesh, forced to witness her brother's every action without any ability to intervene.

She felt Ben extend his control to the rest of her body, moving her legs with an eerie grace and purpose. He walked her towards the bedroom door, his steps confident and deliberate. Jamie's mind screamed in protest, but her body obeyed Ben's every command.

They descended the stairs, each step a reminder of her helplessness. As they entered the living room, Jamie's heart sank at the sight of their unsuspecting parents sitting on the couch.

Ben forced her to smile innocently as she approached their parents. His voice, now unmistakably Jamie's, broke through the stillness of the room.

"Hey Mom, Dad. I just wanted to let you know that I won't be feeling well today, so I won't be able to come down for breakfast."

"Oh, sweetie, are you feeling alright?" her mother asked, concern etched across her face.

Ben used Jamie's body to feign a weak cough before replying, "Yeah, Mom, I think it might be best if I stay in bed today."

Ben started back to Jamie's room. She wanted to scream, as she felt her body becoming aroused, her nipples hardening beneath her shirt. She knew what he planned to do next, and she was powerless to stop it.

As she stood before the bed, Ben slowly began to undress her with a practiced ease.

Jamie felt her body betray her, her arms reaching behind to unhook her bra, her fingers trembling as she pushed down her jeans and panties.

He ran his hands down her chest, tracing the curve of her breasts before cupping them in his hands, squeezing them roughly.

Her mouth moved under Ben's control, moaning softly as his hands roamed over her body, "Whoa... This feels so weird... Yet, so amazing."
