Uptight Step-Sis Let's Step-Brother Use Her

My stepsister Dixie is quite the challenge, she can be very demanding and aloof. It's difficult to grab her attention because she always insists on me completing her tasks before even noticing me. Dixie takes advantage of my foot fetish to manipulate me into catering to her whims just to catch a glimpse of her feet.
Today, she deliberately scattered her laundry around the living room and nonchalantly lounged on the sofa, flaunting her exquisite feet and elegant arches. I plead to worship them, but she demands that I tidy up the mess first before allowing me to touch them. I obey without hesitation, but once I finally lay my hands on her feet, I can't help but fantasize about sliding my manhood between her silky soles.
Craving more of her attention, I lean over and initiate intercourse with my stepsister right there on the couch, despite her indifference as she remains absorbed in her phone. I'm consumed by the sensation of my stepsister's intimate parts. Just as I'm on the brink of climax, she abruptly halts me and warns that if I desire release next time, I'll have to go above and beyond for her.
