Sara Luvv and her stepbro had always been close. They could share anything with each other, snuggled up together on the couch, like the best of friends. When Sarah finally noticed one day how big Ralph's cock was, she asked him if he'd fuck her until she gushed. They had both always wanted to, and Ralph made her cum until the couch was soaked with her juices. "Just don't tell mom!" they giggled, as they cleaned up her sofa afterward.
