My wife was working at her school, even though it was the holidays she had to go in as there were some contractors arriving to carry out repair work.
She had on a button through cotton dress as it was a warm summer day; my phone rang and I pulled up outside to answer it- I was still on the phone 45 mins later and then thought I might as well go back to see how long she’d be.
As I approached her office the window was open and I could hear distinct moans coming from inside.
I crept up and stayed hidden whilst gaining a view.
My 60 year old wife was in a clinch with one of the workmen, a much younger man whilst the other was filming on his phone.
She pulled away and started to unbutton her dress all the way down before letting it fall to the floor.
She stood there in her red silky pants and bra.
The man walked back to her then told her to turn round .
He undid her bra and took it off, reaching Roy d he started to fondle her tits.
After a while she turned round and dropped to her knees; undoing his jeans she pulled them down and then got his cock out of his pants.
He was rock hard and she put her mouth around it and started to wank him at the same time; the other man had stopped filming now and joined them, undoing his trousers and getting his cock out.
She was sucking both of them.
After a while they lifted her up and the younger man made her bend over her desk; he pulled her pants down and she stepped out of them.
He parted her legs and slipped his cock right into her before shagging her as hard as he could; she came very quickly and then turned round; sitting on the edge of the desk she beckons the other man over; he then shagged her as well.
I was shocked but transfixed.
I got back to the car and drove off before returning an hour later; they’d gone and she said nothing.
I’m assuming this wasn’t the first time as she’s always been keen to go in in the holidays, now I know why.
