Your son has a new girlfriend who stays over often. She wears skimpy pyjamas. Tonight she is awake downstairs getting water and you bump into her, she asks you to stay a while and keep her company. She confides in you she doesn't think your wife likes her much. You agree but tell her you like her and so does your son. She confides that she likes you. Before you know it you feel your zip being undone, and her hands wrapped around your cock. With your whole family upstairs you don't want to cause a scene but she's undressing and not listening. Your cock is making its way inside her before you brain even reacts
