Waking up with a blowjob from my sister

My step sister wants it badly. She’s always coming on to me. This week she woke me up with a blow job so that I would help her with her math homework. She then came on to me in the kitchen as our parents were preparing dinner. She does not stop. So I had enough and had give it to her. I took her to my room where I fucked her in several different positions. She then begged me to slip my cock in her tight little asshole. I stretched her asshole further than it has before. Finally, I dropped a huge load all over her face.
