Morning Surprise part 2

Second Part to Morning Surprise.
I was woken at 5pm by my daughter Sandie, she put a cup of tea beside the bed, drew the curtains just enough to let in some light and left. I sat up sipped my tea and was thinking was this morning a dream. The soreness in my cock told me it was no dream. I did not want to rush down stairs, but I knew that staying in bed would solve nothing.
I put on some jogging bottoms and a T-shirt and headed down stairs; both girls were in the kitchen preparing dinner. I honestly did not know what to say. I put my mug into the dish washer. Sandie was peeling potatoes at the sink. I was searching my mind for something to say that would lighten the mood, but the only thing in my head was mush.
“Dad, are you on nights again tonight?” Mel said
“Yes love, I start again at 8pm. What’s on your mind?
“I was wondering when we should tell Mum what happened”

That’s what I was trying to sort out myself. We have always been a very close family, and lies were not allowed. I could not decide if it would be best to tell Joan, my wife as soon as she walked in the door, or after dinner. Her shift finished at 5pm and she would be walking into the house any minute now.
“Girls what do you think?”
Sandie said “ Dad Mel and I have been talking, while you were asleep and we have decided that what happened this morning was what we both wanted for as long we can both remember. You are the kindest, strongest, gentlest man that we both know; we love you more than any thing. Having you as a lover is the most wonderful thing that could possibly have happened to us”
Being in a state of shock is not normal for me. I can normally figure out what to do and what to say well in advance of things happening. But now I was floundering like a freshly landed fish.
“When you say lover does that imply that this morning was not just a one off”
“Hell no they both said as one”
Mel came over and gave me a huge hug, Sandie put down her peeling knife and also came over and gave me a hug and a kiss.
“Dad, we meant what we said we want to keep you as a lover, who better to teach us all about pleasure. We love you and you will never hurt us, put us down, be unreliable, jealous we have found the perfect teacher. We can think of no one else that we would ever want but you”.
Would this strange day ever end, it was throwing things at me that I had never thought would happen, let alone plan for.
