In the hushed confines of her dimly lit room, Berta, a woman of mystery, indulges in her secret vice. She slips her hand beneath her silk robe, seeking the warmth between her thighs. Her fingers trace the edge of her panties, teasingly at first, before dipping inside to stroke her wet, hungry folds. Her breath hitches as she builds a rhythm, her other hand pinching her nipple, sending jolts of pleasure coursing through her. She bites her lip to suppress a moan, her body tensing as she nears climax, her pussy pulsing with anticipation.
