Girlfriend's Sister Led Me Upstairs to Pose Naked

She knows exactly what she's doing to you. She stands there, smiling, in that white lace slip dress, her long blonde hair cascading down. She holds up those pink panties, a question hanging in the air. Your pulse quickens as she leads you upstairs, her every step teasing.

She sits on the bed, adjusting her lingerie, coy and inevitable. She leans forward, her hand running through her hair, and you can't look away. Then she's gone, only to return completely nude, covering herself with a slight regret in her eyes. She lies on her back, eyes closed, hands still over her chest, and your hand strokes faster.

She's on her back again, partially covered now, a faint smile for you. And then she's standing in front of the bathroom mirror, fully clothed once more, a smirk over her shoulder. Your breath catches as she turns to face you. You're hard and aching now. How long will you last? The question hangs as she glances back one last time.
