“W-wait, come on Sakura.. we’re classmates.. You can forgive me r-right?” the blonde pleaded, squirming in his bindings.

His captors red lips curled into a cruel smirk as her small hands formed a hand sign, “Slave Seal activate!”

“W-what?! How did you make a slave seal?!!” Naruto screamed out as markings spread across his body and then receded as fast as they appeared.

Ino grinned, crossing her arms under her large chest, “With my knowledge of the Yamanaka Mind Arts and Sakura’s intelligence, it was easy to design a seal that can control somebody.”

Sakura walked over and undid his bindings, setting him free. “Stay seated.”

Naruto couldn’t help but to obey Sakura’s command, unable to control his own body.

Sakura sat on the bed with a satisified smile and addressed Ino, “So.. what do you think we should do first?”
