Jack's friend screwing Jack's Step mom

Jack is coming home from college to celebrate his birthday party, and his mom, Diamond, is decorating her house in preparation, along with the help of Jack's friend, Seth. What Jack doesn't know is that his hot, horny, big-tittied mother has been feeling lonely ever since her husband left, and now she's eyeing Seth. What Jack also doesn't know is that after decorating, his mom sucks and fucks Seth until he busts a load in her mouth. What Jack doesn't know won't hurt him.
