In the sterile, clinical setting, the doctor's gloved hands explore Lizeth's intimate folds, her big clit throbbing with desire. The doctor's fingers, slick with Lizeth's juices, slip inside her tight pussy, stretching her as she pumps in and out, building a rhythm that has Lizeth gasping for breath. Liseth, watching from the side, can't help but feel her own pussy tingle with envy, her hand instinctively reaching down to rub her own wetness through her panties.
