Mistaken sister for a sister? (2)

Wang Xiao nodded in sudden understanding.

However, Wang Xueying wasn't done yet.

Her eyes, a complex mix of emotions, scrutinized every detail of Wang Xiao's form. "D-Do you guys do this every day?" she ventured, her voice trembling with curiosity and a hint of fear.

Wang Xiao, momentarily puzzled, sought clarification, "Do what?" But then, realization dawned on him, and he comprehended the nature of her inquiry.

Wang Xueying, her entire body concealed beneath a blanket except for her face, turned to face him with a lingering unease in her eyes.

Seeing her like this, a different facet of Wang Xiao emerged. "Do you mean this?" he whispered, his lips brushing against her neck once again, causing her to jump in surprise.

She quickly pulled back, paniced. "What are you doing!?" she exclaimed, her confusion evident.

Wang Xiao chuckled softly. "I already knew it was you."
