One more time... okay?

"I'm home." -- Friday, straight from work, her company ID still around her neck, the two of you say "I'm home" together for the very first time.
You've been together a year. She works at the same company and today you start living together. In the new room, the last cardboard box finally flattened, the kisses on the sofa just won't stop -- and she makes a mischievous declaration: "Tonight, I'm not letting you sleep."
Teased by your ear, a reward with her mouth, the first night in a brand-new bed. Teased again in the bath, then she climbs on top, takes you from behind, and holds you close -- from night to midnight to dawn, and into the morning. Her polite speech slowly crumbling, her sweet voice overflowing with "I love you" -- your whole first night together, every bit of it.
