Use some needles.

With a devilish giggle I select a few needles to bring some "color" to her pale body. With a flourish I pull on a hooded robe concealing my body. I want her fear to be from what I do not my looks. Removing her blindfold I watch her eyes. She shows a little fear that grows when I show her the needle in my hand. I scrape the needle down her neck to her right nipple. She struggles as I slowly pierce through her nipple, her muffled screams frantic.
