My step-sister, Amber, has always been a tease. She's sixteen, blonde, and perfect in every way - from her smooth, tight body to her plump lips. Tonight, as I was trying to focus on math homework, she kept walking in and out of my room, teasingly jiggling her perky tits for attention.
Finally, fed up with the distractions, I snapped at her. "Will you please just go away and let me study?"
Her eyes flashed with anger, but then she smiled slyly. "Fine," she said. "But first, you have to promise me something."
I hesitated, suspicious. "What's that?"
"Promise you won't tell mom or dad," she whispered seductively, her fingers lightly tracing the wetness between her legs. My heart was filled with sadness when I heard the news.
