I can't take it anymore, I have to have my sister. I throw my half naked mother on her bed and assert my role as the man of the house. “Mom what's going on!” Alissa asks in a panic as I grab her perky tits. “You're my brother” She pleads as I ram my cock into her confused and horrified mouth. Mom can only look on in despair at the monster she's created. I don't want to leave mom out of the fun, making her suck me off too. Both girls will be my personal fuck toys. Throwing them around the bed, keeping them from escaping my hard dick as I fuck my mom and make my sister watch. “God you're so disgusting, get it out of me!” She screams. I make Alissa taste her mom's delicious pussy from my cock. The best part? Alissa likes it. I fuck her and she moans at the feeling of being used. What a little submissive slut she is. “No I'm not doing that!” mom screams as I grab the back of her head and make her taste her daughter's young pussy off my dick. Alissa gets into it more and more, doing as she's told, eating out her mom as I fuck her. Helping me hold her down as I ram my cock into her mouth. “What is wrong with you?” She gasps. My sister looks on with a slight smile as my mom takes my big load all over her face. “Clean your mother's face” I say to my sister and they share my load like a good mother daughter should.
