I Fucked Her While Someone Else Saw Us But She Didn’t Know

One warm sunny summers day my wife and I were out for a drive when we both felt a little horny.
Stopping in a wooded area we worked our way through bushes to a clearing that was hidden from sight of anyone.
Soon we got down to it, I had her top up bra off and had just pushed her dress up when I noticed a guy moving closer!
I was alarmed until I saw it was a very old guy.
I carried on kissing my wife’s nipples and as I started to pull her panties down the old guy was only a couple of feet away from us.
I pulled her panties off and the old guy could definitely see her hair fanny as well as her now corkscrew nipples.
I started to finger her and as I did so he unzipped and pulled his cock out and started wanking.
He was well endowed , in fact bigger and thicker than mine!
His cock was now solid.
I dropped my jeans and underpants and moved between my wife’s legs, entered her and started to fuck her while still keeping an eye on the old guy!
The faster I fucked my wife the harder he jerked off.
Then suddenly he spunked everywhere, spurts after spurts of it just a few feet from us.
Then shot my load into her!
As I started to pull out of her he zipped up and moved away.
I never mentioned it to my wife that she had been seen having sex by someone else.
Was a real turn on for me .... maybe I should have let him have fucked her!
