My stepsister and I had sex for poor grades and she gave me a foot job - a fiery vixen

After pulling a dismal C on my math exam, I knew I had to come up with a plan. Enter my stepsister, a fiery vixen with curves for days and a mischievous glint in her eye. She offered a unique solution - if I failed again, she'd do the dirty deed with me. Little did she know, I was primed for a challenge. The day arrived, and there she was, ready to help me out. She started off with a foot job, her skilled toes working magic on my throbbing member. Then, she unleashed her big tits and we got down to business. Her expertise was evident as she took control, riding me like a pro. The sight of her luscious ass bouncing made me even harder. We switched it up with some doggystyle action, her moans filling the room as she reveled in the pleasure. Finally, we ended with her bent over, taking me deep inside her. It was a wild ride that left us both satisfied, and I never had to worry about math again.
