Why employment is never satisfying

Stepbrother is back from college and excited to see his beautiful sister Daisy Stone. He enters her room only to find her cleaning with no clothes on! She is much hotter than he remembered. After getting decent and talking to brother for a bit, the lust between them could not be contained. They begin to sixty nine each other until a creek from the door is heard. Mom and dad are home and this forbidden romance will need to be put on hold. The next morning with Daisy on his mind, stepbro enters the bathroom only to see Daisy brushing her teeth in her undies. His dick got hard immediately, and sister suggested they finish what they started yesterday. Brother wastes no time fucking sister on the sink and leaving her with some home brewed paste of his own, not necessarily for her teeth either. The next day just as he woke up, Daisy was just getting back from a date. She wasn't fully satisfied and needed that good stepbrother dick to help her get over it. Sure enough this freaky family got to work at swapping their genetically similar fluids and one of them even swallowing it down too.
