Mark had stared at me with open lust. I realized it was nice to be desired. I liked having a man looking at me that way--and, the part of my brain that was still a guy admitted, I had a killer body. I was still only fifteen, but I could be a fashion model or a movie star. But Mark was old. The idea of him putting that rusty pecker in me creeped me out.
Dustin had given me so much crap through the years, I decided now was the time to let him know who's the boss.
I used a little of my powers to give myself feminine wiles, and then I crossed the room to my foster brother, slinking the whole way, shaking my hips like an exotic dancer. His jaws dropped open to see me this way, and when I pushed him back in his chair and sat down straddling his lap, all he could do was gulp. I arched my back, waving my suddenly desirable breasts in his face, and pressing my stomach onto his chest. I felt him getting hard under me. He went limp, unable to move or even think. I realized this was even more powerful than my new magic.
Mark and June's eyes drilled into my back; I could feel them even without looking. And I didn't have to guess what they were thinking. June thought I was a slut, while Mark thought his son lucky, and enjoyed the show. My new sexuality had my whole family under my command.
And it felt good.
I leaned into my foster brother, rubbing my breasts along him, and bent inward until he and I were face to face. "Good morning, lover," I purred, then pressed my lips onto his.
Dustin hesitated at first, but then opened his mouth. I felt his tongue jab out and start to prod my lips, so I opened up and let him in. He explored the taste and texture of my mouth, as I felt his arms wrap around me. One hand caressed the small of my back, while the other reached up and stroked my hair. Oh, yes. My foster brother was under my power, and I didn't even have to use magic. I only had to use my nearly perfect body.
At last I broke the lip lock and turned to face my foster parents. I still had my breasts pressed against my brother, but I waved brightly to them. I could see Mark trying to catch a glimpse up my sleeveless blouse, and I smiled at him, all pearly whites. "Good morning, Mark. Hi there, June."
June finally found her voice just in time to scream at me. "Tyler Michelle Foster, what do you think you're doing, sexually assaulting your own brother like that?"
"Foster brother," Mark whispered.
"Shut up," June hissed at him through clenched teeth. "I saw where your eyes went, you and I will talk later."
"Yes dear."
"Well?" June demanded. "What do you have to say for yourself, young lady?"
I grinned. "I kissed sexy young Dustin," I explained, "because..."
