Single mom is chatting, got bored then got fucked!

[Sarah is sitting at her computer, tapping away on her keyboard while chatting online. She stays in her pajamas all day, not realizing how sexy she looks. Her son walks into the room and sees his mom's bare legs spread open.]Son: Mom, you have a butt crack showing.Sarah: (jumping up in surprise) Oh my god! I can't believe I didn't even notice. (She adjusts her top, bending over slightly to show her tight ass) I must be really bored today.[The son, Craig, smirks to himself. He knows his mom is sexy and he gets a thrill from seeing other guys admire her online. As Sarah sits back down, Craig decides to join in on the chat.]Craig: Mom, who are you talking to? Can I see the conversation on your computer screen?
