Training mother needs her protein shake

Mother is in full training mode, dressed in her gym cloths she is ready for a good workout. As part of her normal routine she would suck off her boyfriend in the morning get super turned on then use that to push her work outs. But she broke up with her boyfriend so she could focus 100% on her training. As she walks by her son, sitting on the couch, a wicked idea goes through her mind. She sits next to him and starts rubbing her body. She slowly pulls off her cloths as she moans in pleasure. Her son does not know what to do as he watches his mother. She turns to him and explains that she needs some protein for her workout and starts to suck his cock. He explodes into her hot mouth, and she swallows it down. She thanks him for his help and leaves for the gym.
