We spent the whole day making love. By the time Marcus walked Sarah downstairs it was almost time to pick my daughter up from college. He came back in the bedroom sheepishly.

"So," he said.

"I can't believe we did that," I said.

"You were amazing," he said, kissing my cheek.

"I should be made, you know."

"But you're not?"

"Well, I'm not happy I had to come home and find out this has been going on, incidentally for how long?"

"After Ian died. I don't know how it all came about; it was one of those things."

"One of those things?" I said arching my eyebrow and feeling a pang of jealousy.

"Well, if you want me to be honest, I have to admit I was attracted to her when we went to the funeral. Then one day I saw her at the supermarket and we chatted, then another day I saw her again and we had coffee and then one thing led to the other and we began seeing each other like this when you weren't home."

"What!"

"Well, not every time you weren't here, just when we could hook up."

"So how many times?"

"Don't get shitty," he said, "look how it was for you. You didn't even know I was there and you got yourself all hot and horny before I even entered the room, so don't throw stones okay?"

"Okay, it's just that I'm not happy you did this behind my back. That you were seeing another woman, Marcus."

"You're making a big deal out of this and spoiling what we all had today, you know that, don't you?"

"Yes, I know but I feel like the victim here, because I didn't know."

"Well, now you do, so what do you think? Want to do it again?"

I pouted, wanting to make him suffer but he didn't look like he was upset or anything, only eager to get this issue over so we could work out the next chapter in our lives ... and I wondered myself where this could lead.

"Not a word to anyone."

"When can we do it again?"

"What the three of us?"

"No, just you and me," he said mischievously.

"Do you even have to ask?" I laughed and pulled him to me wondering how on earth we'd ever top today, but already planning to do exactly that.
