Yes, she wanted me to have video'd it after all

Melanie was clearly getting a little turned on by the thought of Gina and Dan having sex.
I pulled my wife to me and kissed her. As she responded to my kiss I slid my hand into her pants and began massaging her. She was already wet and as I rubbed over her slit she rapidly soaked her panties.

"So, how big exactly was Dan's cock?", my wife asked. Clearly she found his thick prick fascinating.
"I don't know, but it looked thicker than mine I guess. It looked so big, especially in her. She looked so tight." As I said it I slid my fingers into my wife's slit. First one, then a second and third easily followed; a testament to how wet and aroused my wife was getting.
I stroked her vigorously with my fingers as I described how Dan had been pounding his cock into Gina.

"Fuck, that feels so nice baby", my wife cooed; her eyes closed.
"You're so wet babe, you really like me having watched them huh?"
"I... yea I guess I do, it's so... naughty."
"It was, wasn't it", I began. "It'd have been naughtier if I'd have gone in and joined them though."
"MMMmmm, yea that would have been really naughty. I bet you wanted to as well."
I was about to object when she continued, "you probably could have too."
"Really? You think so?"
"Oh yea, every woman secretly wants to have two men. You could have fed her your dick for sure."
"Oh, well, maybe I'll do that tomorrow night then!" I quipped.
"Right, you'll do that huh? I don't believe you. If you were going to you'd have done it then and there."
I smiled to myself, knowing I'd done just that.
