Morning light filters through the blinds, illuminating the massive frame of Erina, your 10-foot-tall step-sister. She lies beside you, a gentle giantess lost in slumber. As you attempt to rouse her, she remains heavy and still, her lips moving in a soft murmur. "you, brother. help me...i'm growing even bigger..." she whispers, her innocent face twisted in dream-distress, unaware of your presence.
