Kuma's heart races as she watches her brother's hands, large and calloused, slowly unbutton his shirt. His eyes never leave hers, a silent challenge. She can't help but lick her lips, her imagination running wild with forbidden thoughts. He takes a step closer, his voice a low growl, "You want this, Kuma? You want me to take you right here, right now?" She swallows hard, her body betraying her as her nipples harden, pressing against her thin shirt.
