In the sultry confines of their shared apartment, a brother, driven by his sister's absence, succumbs to his desires. He strokes his throbbing cock, the sound of his hand meeting flesh echoing through the empty rooms. His mind drifts to her, the curve of her hips, the laughter in her eyes. He imagines her joining him, her soft hands replacing his rough ones. The fantasy is interrupted by the creak of the front door. He freezes, his heart pounding, as she steps inside, her gaze landing on him, his cock still in his hand. The air between them crackles with tension, unspoken words hanging heavy in the air.
