"I can't have enough of you Gelma Moriaty." He muttered beneath his breath more to himself than her.
Gelma swallowed the invisible lump in her throat. Watching his black eyes turn red all of a sudden. She staggered backwards but his strong hold round her waist supported her and so she couldn't trip and fall from the shocking sight before her. She knew there was something mysterious about him, she couldn't put her finger on it but she was a hundred and one percent sure he was far from humane.
He stood dazed as he starred at her through his long lashes and his long bangs while pinching the bridge between his eyes.
"Nathan...", her broken voice seemed to have jerked him out of his daze. He then realized he was no longer in his human form.
He clenched his teeth and his fist until they were white. He grabbed her by her hand and pulled her to his room which was in his office. Once he dragged her in, he shut the door closed without touching it by use of his powers he had kept hidden for hundreds of years. Immediately the door went shut, he pinned her on the door and crashed his lips on hers.
