I was so sick of my stepson's girlfriend's attitude. She was way too sweet and modest to please him. All she wanted was for someone to suck his cock, and she kept saying no. I was not going to let my stepson have blue balls, so if his girlfriend was not going to take care of his needs, I'd do it. It all started simply. I let him finger my pussy at our home so he could see what I could offer him. I even licked my cum off his fingers to erase the evidence. Then, the three of us went shopping, and when I saw his boner, I knew that was the perfect moment to get a taste of his beautiful, fat, big cock. I didn't know his girlfriend would catch us. They got into this awful fight because of a simple blowjob, so I had to intervene and tell her that if she wanted to be a part of this family, she would have to share my stepson's dick. I was shocked when she agreed, and even more surprised when she let me play with her smoking-hot body. Turns out all we needed to get along was a public threesome.
