The camera zooms in on your raven-haired stepsister, her luscious body tightly bound in a black lace corset, her pale skin glowing under the warm light. She's standing before a full-length mirror, her hands slowly reaching down to part the floral lace of her panties. Her eyes are занятые with her own reflection, and she hasn't noticed you steal behind her.
As she slowly slips her finger into her moist folds, her panties grow darker, the evidence of her arousal becoming increasingly visible. You can see the moisture gathering at the crotch of her panties, slowly seeping through the lace and trickling down her thighs. Her breath quickens, and she bites her lower lip as she begins to finger herself, her hips gyrating rhythmically.
Suddenly she lets out a muffled moan, lost in the pleasure she's experiencing.
