Stepmother's solo sleeping habit drives her son away

A man has some suspicions about his stepmother's strange sleeping habits. He feels like she's up to something when she's supposed to be resting, and he can't shake the feeling that she's getting some naughty pleasure while he's not around. He decides to confront her about it, but she denies anything is wrong. However, he's not convinced and decides to set up a camera to find out the truth. What he captures on tape shocks him. His stepmother is pleasuring herself, touching her big, beautiful tits and moaning softly. He's disgusted by what he sees and can't bring himself to talk to her about it. He's not sure what to do, but he knows he can't keep pretending everything is normal. He's not sure if he wants to fuck her or not, but he knows he definitely doesn't want his son to be thinking about her in that way.
