My step-sister Isabel Moon comes into my room looking really down and out when I ask her what's wrong she told me she got stood up for Valentine's day. I really felt bad for her and I wanted to cheer up, she is my step-sister I don't wanna see her upset. I ask her how I can help, she just wants me to fuck her with my big dick. I always wanted to fuck my step-sister, she is one of those sexy nerdy girls. I love the way she takes my big cock, I can barely contain myself and busty right into my step-sister's pussy.
