Derek nipped at her mouth, chastising her for the 'unwanted gift' comment before he answered. "A gift that I didn't know I needed until it had been given to me," he replied. "But Eterna is all you have to compare me to, and I know that she treated you as an object. You became used to it, began to see yourself as an object to give pleasure, a slut who needed to be used. A bitch in heat."
His hands moved down her sides, cradled her hips, angled his hands inward so that his thumbs brushed against her lips, still wet. It wasn't that Derek didn't think of Allison in those terms. He did. Like any human, she had needs that could only be filled by a Master, but she wasn't only that.
"I wanted you to feel comfortable with what you need, to dissociate it from Eterna, to not be ashamed by it, first." In time, he'd planned on seeing to her other needs.
