Uptight Step-Sis Lets Brother Use Her

My stepsister Dixie can be a real bitch, she is so stuck up about everything. I can barely get her attention she is always making me do her chores to even consider acknowledging me. Dixie uses my love for her feet to her advantage making me do things for her just to be able to look at her feet. She made a real mess today with her laundry all over the living room, Dixie is purposely sitting on the couch... barefoot showing off her amazing feet and high arches. I beg her to taste them, she demands I clean the mess before I can touch. I comply of course but soon as I get my hands on her feet all I wanna do is slide my cock right between her soft feet. I need more, I want her attention, I bend over my stepsister and start to fuck her right on the couch all as she ignores me and is just looking at her phone the whole time. I do not care I just love the feeling of my stepsister's pussy... Just as I am about to cum, my stepsister stops me and tells me next time she is gonna need me to do more for her if I wanna cum.
