I Hypnotized My Sweet Little Sister

Jimmy's ashamed to admit that he's attracted to his busty sister. Sophie's 19-years-old, bubbly and beautiful, and absolutely adores her big bro. When she brings home a pair of “magic” sunglasses, Jimmy seems to gain the power to hypnotize her. But is that really what's going on, or is Sophie giving him permission to fulfill his taboo fantasies?

Excerpt ~~~~~

Sophie hugged a thick pillow to her body and buried her face in it. “Oh my God!” she moaned. “I didn't know you were home!”
“Yeah, I can see you were occupied.”With a growl, she lobbed the fat pillow at my face. I took it on the chin. “I'm sorry,” I said. “I only came up here because I thought you were hurt. I heard--""I know what you heard!” she moaned. She clutched her face in her hands. “Can you go, please?""Because you were--? Hey, everyone does it.""No!” she shouted. “Jesus, Jim, I'm naked. You can't be here!” But I just couldn't go. I was mesmerized by the veil of sweat that covered her juicy thighs. Even the way her legs hugged her pillow was provocative. She clung to it, but not too closely, as if she was hot to the touch and feared the linen would set her alight. Her smell, her vulnerable whimpers, the way my shirt trembled on the tips of her quivering…I sat down in the chair beside her bureau. “It's nothing to be ashamed of,” I said.Sophie gathered the pillow tighter to her body and grimaced. “I don't know what's wrong with me,” she said. “I've been up here all day…""Y-you have?”She peered at me through the strings of her wet hair. “It's like we were talking about last night. Have you ever been so horny that you did something horrible? It's like my body was triggered or something. I've just…” She pushed tears from the corners of her eyes. “I can't talk to you about this--""Tell me,” I said. I didn't hide the hunger in my voice. She gazed at me, quizzically at first and then maybe in fear. “I woke up this way,” she said slowly. “You ever get…blue?""Of course,” I said.”It happens to girls, too. Like, if you're making out with a guy, or he's grinding on you, and then you get interrupted. Or if you have sex but it's not enough and I don't finish…” She winced again. “Jim, I shouldn't be telling you this--""No,” I said. “I want you to tell me.""But it's gross.""You're wearing my shirt.”Her skin flushed and she pulled the flaps tighter over her chest. “I wear a lot of your stuff,” she said defensively. Was that true before last night? Or was she searching for my smell? I'd left her unfulfilled last night.I had hoped that the hypnotism would clear her mind of our indecent act but I hadn't counted on muscle memory. Nor, I realized, had I allowed her to climax.
Maybe her memory was blank…but her body screamed for release.
