Part 1 - Well Planned Seduction - My step-daughter Aidra asks to use my shower. Then I hear her cry out and I worry she slipped, but I open the door and she is masturbating and orgasming in the shower! She sees me watching and is not embarrassed at all. I close the door and get into bed, my dick suddenly like a steel bar. Aidra prances out and asks if she can rest with me and then jumps into bed. She lays very close, moving against me, her hands starting to go places they shouldn't. Then she tells me she slipped a blue pill into my vitamins. My dick is painfully hard, and she takes advantage. I can stop her, I can tell her no and be firm. I don't though. I let her keep going until I lose control.
