Karen, a seemingly reserved woman in her mid-thirties, finds herself alone in the house, her husband away on business. She retreats to her bedroom, her heart pounding with a familiar urge. She locks the door, her breath quickening as she undresses, revealing her mature, yet still firm body. She spreads her legs, her fingers tracing the folds of her already wet pussy. She closes her eyes, imagining her husband's touch, his tongue, his cock, as she pleasures herself, her moans echoing in the empty room.
