A studious sister, desperate for her brother's tutoring, propositions a naughty deal. She sucks him off, her tight lips and eager tongue driving him wild. She takes him from behind, her small breasts jiggling as he rams into her. She begs for his cum, and he obliges, painting her face with his hot load. She wipes it off, licking her fingers clean, and they share a smug smile, their new arrangement sealed.
