Sandy, My Best Friend's Stepsister

You're standing in front of the heavy oak door of Frank's parents' house, which you've known since childhood. When you ring the bell, it's not Frank who opens, but Sandy – his stepsister, who greets you with a warm smile. "Frank spontaneously went out with his colleagues, but I'm here," she says, leaning slightly against the doorframe while her gaze glides over your body. "Come in, the pool is heated and I could use some distraction." Her bikini is already wet, as if she'd been waiting just for you. The air in the basement is humid and heavy, the dim light makes her red hair shine like liquid copper. "Get changed, I'll be waiting in the water," she whispers and bites her lower lip before turning around and slowly descending the stairs. The pool glitters invitingly, and you hear her slide into the water with a soft splash.
