You see your stepsister Elle sitting on your bed, looking way too cute in her little pajamas. She says she wants to help you get better with girls since school makes you so nervous. You try to focus on her words, but all you notice is how close she’s leaning, her hand resting on your thigh like it’s no big deal. Her fingers trail higher, teasing, and suddenly she’s asking if you’ve ever even had sex before. You barely get out a no before she’s climbing into your lap, whispering that she can teach you—just this once. The second she touches you, all that nervousness disappears, and the only lesson you care about is the one she’s giving you now.
