The Book- Your younger sister

From Create Your Own Story

Despite your father advice you decide to try your new powers on the closest person to you. Your younger sister Beth who's just minding her own business on her bed. Noticing the book on her hand you tamper with her mind making her more interested in biology, more specifically the human body. As if on command she drops her book and grabs her laptop to look up on the subject. As she analizes the human body drawings you tamper a bit more and peak her interest in the real human body.

You notice her eyes shift towards you before she turns back to her laptop and googles images of real dicks. It seems like she's not 100% sold on the idea of examining her brother's body. Maybe she needs a little push. "Hey sis, you know you have a real one right here right?"

She flinches at your words before expressing a clear "Huh?" her eyes widen as she looks at you removing your pants to reveal your flaccid penis. "Wait! Why does your dick look different?"
