Only mention having watched Gina and Dan

I pulled into the garage and went inside where my wife was just finishing dinner. "You could have called you know, I gave up waiting and just decided to finish dinner. If you'd been any later yours would have been cold." Some welcome home...
"Hi honey, I'm home," I replied sarcastically.
"Sorry, I just wish you'd call when you're going to be late"
"Okay, I'll try to remember in future," I replied.
"So, why were you late today anyway?"

"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 saw him having sex."
"What?!" she almost yelled, "you saw Dan and his wife having sex?"
"Umm, not exactly... it was with our receptionist."
"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."

"That's so naughty baby, did you watch them for long?", my wife enquired, clearly interested.
"Yea, he was really giving it to her."
Melanie punched my arm, "you should have filmed them so I could see!"
"Yea, I should have I guess. It just didn't come to mind. I was surprised at the size of his dick, and she was loving it so much. I don't know how she could fit it in, she's so small."
"Did you go in and join in?" she asked all of a sudden.
Somehow I managed to lie without being obvious, "No, I swear, I didn't want them to see me so I got out of there and came straight home."

My wife looked at me, right in the eyes, for a few moments before responding simply, "okay."
