Honesty is the best policy

"I uh, was working on some stuff I couldn't get done during the day..."
"Oh, ok"
"Yea... and then on my way out as I turned the lights off I noticed Dan's office light was still on."
"Oh? And then?"
"Well, I went over intending to just go in and turn it off but heard noises... and check this out."
I pulled out my phone and set the video playing, then turned it so my wife could see.
"What the hell!" she almost yelled, "Dan and, is that your receptionist?"
"Yea, her names Gina"
"Well," my wife laughed, "you did say she had no experience, I guess we now know how she get the job!"
"Yea, I guess she's going to be around a while now. What's that joke, Confucious say 'receptionist not permanent fixture until screwed on desk', Dan's sure making sure she's screwed down hard."
On the screen Dan had just rolled Gina over exposing them both more.
"He sure is, he's really giving it to her, and look at the size of him, I don't know how she can fit it in, she's so small. "
All of a sudden the view changed, we'd got to the bit where Gina saw me and I'd ducked down. Unfortunately the view was now off my cock going off in my hand.
"What the fuck, you sicko, you were jacking off watching them! And she saw you. She started playing with her tits for you too. Did you go in and join in?"
"No, I swear, I got out of there and came straight home."
The sudden slap to my face clearly indicated my wife didn't believe me.
"Seriously, look at the time on the video. You know how long it takes to get home, and the time I arrived. I swear I just left then."
My wife looked at me, right in the eyes, for a few moments before responding, "yea, you're right I guess. Sorry about that... I can't believe you videoed them while jacking off though. You're so bad."
"I couldn't help it, I just got turned on by it... didn't it turn you on too?"
"No," my wife replied simply. Quietly. Too quietly.
"Really? Are you sure?"
Silence.
"Shall I play it again?"
"Okay," she replied almost whispering.
