Every two weeks Sharon and Bob visit us. I'm sure you know what happened. 

Sharon and I were cooking, it was warm so Paul and Bob were in the garden. 

"I enjoy Paul." Sharon told me. The was no need to tell me.

"I enjoy Bob."

"So do I. They are different."

"That's true." I continued the conversation. 

"But you enjoy the difference, the way they kiss, touch and fuck."

I flushed at the sound of that word, I still do. 

"Yes I like the difference." I recovered. 

"There are more differences out there."

"Are there," I struggled to understand. "Other men?"

"Yes, other men." 

"What are you suggesting?" 

"We know another couple, not so much salt." Sharon stopped me.

"Sorry" I did not tip my handful of salt into the stew.

"Would you like to meet them?"

"Like we meet?" I asked for clarification. 

"To experience the difference."

"I don't know, will Paul say?"

"He will say yes, men always do."

"They are a nice couple." Sharon encouraged. 

"We could meet them for dinner." I conceded 

"If you like."

"Just dinner." I demanded. 

"Just dinner." Sharon confirmed. 

We put the stew in the oven and went into the garden with wine.

The little cottage is in the middle of nowhere.

We appreciated our differences. 

We met Tim and Lucy the following Friday. 

They were younger than us. They had good manners and I kind of liked him.

"I have to pee." Sharon whispered.

When I never moved. "Coming?"

I followed to the toilet.

"Do you like him?" Sharon asked.

I knew what Sharon was asking. I nodded.

Sharon hugged me. She held her cheek next to mine. "Good girl." She stood back. "I need to pee."

We did what we did and went back.

We went to Lucy and Tim's house. They had a spare room. The floor was covered in mistresses.

"Would you like a drink first?" Lucy asked.

"No, we had wine with dinner." I threw myself at Tim, I really did. I wrapped my arms around him.

We did not undress, only enough to do it. I heard Sharon say condom. I looked round as Tim put it on. Everyone was looking. I knew it was good. I did not know why it was good but it was.

It was only when we finished that the others started.

We spent the night.

We said goodbye in the morning, Sharon hugged me.

We all said we would meet again.

My mind was spinning.
