My grateful sister sucked my dick and let me fuck her

I thought I was dreaming when I saw my sexy stepsister barging into my bedroom in the morning, wearing a skimpy pink fairy outfit with pasties covering her nipples. As I tried to figure out what was going on, she begged me to keep quiet. A hardly any seconds later, I heard knocking on my door, as my stepsister hid under the sheets next to me in bed. It was my dad, wondering if I knew anything about her. I made up some lame alibi for her, but my dad bought it. Once our daddy was gone, this guy got off from beneath the sheets, profusely thanking me for covering up for her. She too noticed that I was sleeping naked and I had a massive morning wood. Since that babe owed me one, that babe offered to assist me with my pulsating erection, taking my hard dick in her soft hands and sucking on it. Man, I couldn’t make no doubt of my very own step sister was giving me a oral sex in bed! My knob is so big, this babe could hardly fit it in her tiny mouth and looked so fucking sexy eating my sausage. The little slut stripped exposed and straddled herself on top as I pushed my boner deep inside her gushing muff and we started to fuck! My bare sister rode on my dick in cowgirl position, moaning so softly. I fucked her precious and slow, taking my time, flipping her over for some reverse cowgirl action. I put her down on her hands and knees, pulling her arms behind her back, burying her face in the pillows as I fucked that dripping wet cookie doggy style from behind with my palpitating morning erection. She looked like a pixie and fucked like a woman! I finished her off in missionary position during the time that this babe rubbed her muff!
