Tim was twenty five years old and had been married to Jane for just a year.
They lived with Jane's parents in St Johns Wood, London. It wasn't too bad for him with regards to privacy as his father in law worked away a lot and his mother in law, like any woman who was married to a rich and successful man, was a lady who lunched. She was on several charity committees and spent most days out of the house.
The house itself was a huge Victorian property in one of the nicer parts of London. Toby was slightly overwhelmed by his in-laws especially his wifes's mother who at fifty two years of age spoke extremely politely and was a very straight laced type of person. Toby felt he had to be on his best behavior at all times when he was in the house with her.
Hopefully it wouldn't be for long as the reason they were living there was so they could save for a modest property of their own.
When Tim first met Jane in a bar in Central London he had no idea just how wealthy her parents were and in fact they had started living together well before he met them. After the wedding his parents in law wouldn't have their daughter spending married life living in his pokey little flat so they insisted that the young couple move in with them until they could afford their own place.
Tim worked for one of the private banks in the City and was about to take a very important exam in the next few days so his manager told him to go home at lunchtime and do some revision.
It was just after one thirty when Tim stepped out of St John's Wood underground station and made his way on foot down the leafy avenue towards his in law's home.
When he got to the house he cursed as he saw his mother in law's car in the drive. It looked like the window cleaners van was parked outside too.
'So much for peace and quiet to work on my revision,' thought Tim.
He decided to use the back entrance seeing as his mother in law was in rather than search through his briefcase for his keys.
Opening the back door he saw that there was no one in the kitchen and wondered if indeed she was out.
Then he heard a faint moan. Walking on through the house the moans were getting louder and there was a sound of rhythmic slapping, like flesh on flesh. It seemed to be coming from the sitting room.
Putting down his briefcase gently not to make a noise he moved closer to the sitting room door that was open slightly.
On looking into the room he had to stifle a gasp. There on the bottle green leather sofa was his mother in law naked except for her six garter black satin suspender belt, black stockings and wearing her black high heels. She also wore a string of pearls around her neck. What was more surprising was the fact that the eighteen year old black window cleaner was between her thighs and giving her the fucking of a lifetime.
Her legs were wrapped around the young boy's waist and she was urging him to fuck her harder.
'Oh God, yes. Go on, I'm nearly there. Good boy, that's it...oh my,' she cried.
Suddenly she looked up and she saw Tim standing there, looking on.
She was about to scream but an almighty orgasm took her breath her way and her eyes went to the top of her head as she came.
Tim thought that this was the time to beat a hasty retreat and walked upstairs to his bedroom.
Inside he undressed, hung up his suit and tie then threw his shirt and underwear into the laundry basket before turning on the shower in their en-suite bathroom.
