One day, Tim wandered into the living room and found his sister looking all bookish and sultry. She was laid out on the couch wearing a mid-thigh-length black skirt and a white blouse with a book in one hand and a sharpened pencil in the other. Her glasses were low on her nose and her hair covered one side of her face.
Tina beckoned to him with her finger and Tim obeyed, sitting at her feet on the couch.
"Do you want to play therapy with me?" Tina asked her little brother, when they were sitting together.
"Okay," said Tim, "how does that work?"
"Well, I'm a sex therapist and you have to pretend to have a sex problem. So, what's your sex problem?"
Tim felt a little embarrassed by his sister's proposition, but at the same time, he was still excited by their last play session. After a moment, he said, "So, I have this sister, and she makes fun of me every time I jack off. Now, I get so anxious about it and I can't do it anymore. Every time I try to get hard, I remember her scolding me and laughing at me and I just can't. Can you help me, Miss Therapist?"
"Certainly, young man," his sister said, in character, "I can help you with that problem. I will need to examine your cock, and have you masturbate in front of me. I might even need to touch your cock and manually stimulate it. Do you agree to these treatment conditions?"
"Yes, ma'am," Tim said, trying his best to affect the character of a therapy patient.
"But first," she said, "I need to ask you some questions. What do you fantasize about when you pleasure yourself?"
"Well, naked women, I guess."
"Can you be more specific?" Tina probed, looking over the top of her glasses.
Tim looked thoughtful for a moment, and said, "I guess I like brunettes with glasses who seem prim and proper but who are really sexy in a domineering sort of way."
"Oh, I see," she looked him in the eye, "you are attracted to librarians and therapists."
Tim nodded slowly, "I never really thought about it, but now that you mention it . . ."
"Let me ask you this," she continued, "have you ever fantasized about your sister? Sexually?"
"No! Of course, not. That's gross."
"Tell me the truth, young man. Therapy does not work if you lie."
"Okay, okay. Sometimes."
"Very good. Now we are getting somewhere. Have you ever pleasured yourself while fantasizing about your sister?"
"No way."
"You have never once thought about her with your hand on your throbbing cock, thinking dirty thoughts about your beautiful sexy big sister while you stroked up and down on your dirty dirty little cock until you got big and hard? Not even once? I find that hard to believe."
"Okay, maybe once. Or, twice. But, she made me. She made me play with her and touch myself and I came and got it on her and she got mad at me and scolded me, then she played with me again and tickled me and I came on her again and she made fun of me. It's not my fault!"
"It's okay young man," Tina leaned forward, putting her hand on Tim's thigh, "you are in safe hands, now. You are in my hands, and this is a safe place. Do you trust me?" she asked as her hand moved further and further up her brother's thigh.
"Yes," he gulped.
