You arrive at your Mom-in-laws house early in the morning to fix her broken washing machine, but when you arrive it has already been fixed by her neighbour. She keeps apologising for the inconvenient journey you've had, but you don't mind.. you love spending time with your wifes Mom. She offers you a driink and makes small talk, before asking you why you and her daughter are now in separate beds. You tell her it's because you've not been getting on lately, and you think she's actually cheating on you. Your Mom-in-law isn't surprised, she knows what her daughter can be like.. soon, you are both flirting.. just a little bit.. and before you both know it your banging your Mother-in-law, not even bothering to use a condom. It's ok though.. you can just tell your wife that the washing machine took longer to fix than you thought it would ;) xxxx
