~•No Escape•~“Are you running away from me, my sweet girl” spoke a voice in the hallway that made her stop in her tracks. The hallway had turned dark with only the wall lamps that burned brightly casting the shadow of the man on the floor as he slowly emerged from the other end.“What are you doing here, your majesty,” She said and bowed immediately as she saw him approach her with slow but steady steps.“You haven't answered me, sweet” The man said with a sweet smile that made her wary and he heard the way her heart skipped a beat. He stood before her and used his index finger to raise her chin. He tilted his head as he gazed into her green eyes that looked back at him with fear.He took a step forward closing the distance between them and his eyes narrowed when she took a step back, but that didn't stop him from cornering her.“Did you think you can escape from me?” He continued to question and she didn't miss the mockery behind his words.“I…I” she felt her words tied to her tongue because of the man's daunting aura. She felt him trace her forehead with his finger down to her jaw. He continued moving his hand down to her neck and to the top of her swell and her thudding heart hitched when his hand continued to stay there.“Did you think you can escape from me?” He bent towards her as he spoke. His breath fell on her neck which sent a jolt that traveled down her body.“I told you, you're tied to me and me to you”_______________________Perdita Kartar was a winsome yet strange young lady.
