Finding my wife with fucking a young man

I came home from work early to find the lawn mower on the drive and the front door ajar. I went in quietly and heard my wife Julies voice from the bedroom to someone saying "deeper...faster...yes,fuck my little pussy." I came home from work early one afternoon to see the lawnmower on the drive and the front door ajar.
I went in quietly and could hear my wife Julies voice saying to someone in the bedroom, "yes, deeper....faster....oh yes.....fuck my little pussy....keep going".

I made my way quietly to the bedroom door to find my wife on the bed, her slender legs wide apart,her pussy  being frantically pumped away by the 19 year old student who cut our lawn each week.

My first instinct was to go mad, but they still didnt know I was watching.

I then found I had an erection that was about to burst my trouser zip.

I watched for a while, then suddenly realised she wasnt on the pill anymore, cos I had had the snip after our second child.

I went to pull him off her, his bum bouncing up and down like a man possessed as he pounded away at her, but she kicked me away with her right foot.

"Keep going......deeper......oh yes....deeper...thats good....fill my little pussy....oh yes" 

But then her legs wrapped around him and her hips began to buck, his pumping stopped as he collapsed on top of her.

I said to him as he pulled his spermy cock out of her, you better leave....NOW!  He hurriedly pulled up his pants, grabbed his trainers and left.

Now Julie smiled at me and said. pulling her cunt lips apart, look.

She squrited out some of the thick creamy sperm, and said "my little pussys been naughty...it needs to be punished.....put your cock in!"

I didnt need any encouragement, I was up her in a flash. Lubricated by the sperm,I fucked away at her pussy like a rabbit , the best sex we have had in 20 years of marriage.

My orgasm was fabulous, her hips bucked and convulsed like never before.

Since then, our grass cutter is a regular  welcome visitor, and I am happy to watch while he pumps away at Julies pussy, cos I know I will be asked to punish it after because its been a naugthyspunky cum pussy.
