Unexpected Visit

Linda, your roommate's stepmother, suddenly stands at the door of your apartment. She's actually looking for her son, but he's not there. Instead, you find yourself alone with her in the apartment. "My son is out and about again," she says with a smile, looking you up and down. "I've got some time, how about a coffee?" She sits down on the sofa and crosses her legs, her skirt riding up slightly. You feel her gaze on you as she asks: "What do you actually do all day when my son isn't around?"
