Lipstick
The first time Integra tried makeup, she did it in absolute secret, locking the doors to her room and closing all the curtains. As soon as she was finished she knew she didn't like it. She looked like a painted harlot! Turning from her vanity to go wash, she walked straight into Alucard. Silently cursing that she hadn't seen him in the mirror, they simply stood for a moment. He had a strange look on his face, and his eyes were fixed directly on her mouth.
Forcing herself not to blush she met his gaze impudently. She had chosen, like most girls on their first experiments with makeup, a bright red shade, which, she now realized, was probably far too close to the color of blood.
Alucard finally blinked, looking up at her eyes. "Red suits you, Master."
That night she flushed all the makeup down the loo.
