The time has come for my step-sister to have the orgasm I want her to have. I look at her crotch and notice she's wearing sexy panties. Maybe she is a slut afterall? I rub her pussy and pull those panties up her pussy to warm her up. Then I take my powerful magic wand vibrator and give her clit a little buzzing. Is she enjoying it or is she just fuming mad at me? Hard to tell, she's got my worn panties taped in her mouth! I'm not gonna stay and make my step-sister cum though but I am gonna let her have that orgasm. I care about privacy and wish my step-sister did too so she wouldn't keep an eye on me all the time. I tape my vibrator to her left thigh so it's pointing at her pussy and against her clit and then I tape those thighs together. I leave my tape bound little step-sister with the buzzing sound of my vibrator doing its thing and from the other room I hear how it's making her cum over and over again!
