"He's big, isn't he?" I asked, not knowing what answer I wanted to hear. "He's got a big cock, right? A lot bigger than mine?"

"We don't have to do this," My wife replied. "This was really your idea."

"You want to though, don't you? You want to fuck him right?" I asked. I moved my hand to her pussy and slid a finger in.

My wife whimpered as my finger went deeper...

"You're wet," I said. It was then and there that everything was decided. "Yes, keep going, I want him to fuck me, I want to feel his big cock inside of me..." She moaned.
