The next months were beautiful. Val was now living with Jack and her Mum. The sex was terrific, especially with Gran. There was so much variety, both Gran and Val loved variety.
The Christmas holidays had been a problem because Mum wanted me to spend Christmas at home.
Most weekends, I was playing rugby or golf and had to stay with Gran.
I had to drive to Gran’s most days to keep Gran and Val’s spunk levels high.
I enjoyed spending time with Mum. She was a gynaecologist and an urologist with her own Clinic.
My father had a substantial property company, which Gran had given him. Gran was a very wealthy woman, though she played everything down.
Babs, Jack’s Mum, was also the doctor that Gran and Val used. Val was still on the pill, though she hadn’t told Babs that she had a new lover.
The Easter holidays were going to be a problem, but then Babs had arranged a fortnight’s holiday in France, visiting vineyards.
Gran and Val were happy about this as Jack would stay with Gran.
Three weeks before Easter, I received a message from my Mum asking me to phone her on her smartphone as soon as I could.
I called her back immediately, Mum said, “Jack, I have unfortunate news, your father was involved in a very nasty accident two hours ago.
“He was killed by a lorry when he stepped out onto the road. While he was on his phone, the side mirror struck him on the head. He was nearly decapitated, and he died instantly.
“The lorry had a dash cam, and the police told me it was an unfortunate accident. Dad stepped into the path of the lorry.
“The lorry driver could not have avoided hitting him. Could you come and help me get things sorted out here?
“I don’t know how to tell Gran about this. Can you give me any suggestions?”
I replied, “Mum, I’m so sorry to hear this. At least it was quick. What a shock, I can come now, will I come, or where do you want to meet?
“I believe it would be better if I told Gran, I’m sure that Gran will accept it as an unfortunate accident.
“I will tell her you are taking it badly, and I will have to help you with the funeral arrangements.
“Mum, because of my university commitments and the end of term, could it be possible to have the funeral on Saturday?”
Mum replied, “Thank you, Jack, I appreciate you telling Gran. It would be best if you told her.
“I’ll be at home. We need to go to the morgue to identify the body. Can you stay the night, as there’s a lot to do tomorrow morning?”
I answered, knowing that I would need to give Gran a quick fuck so I could stay the night.
“Mum, I have things to do, but I’ll be home in a couple of hours. The only thing that could hold me back is telling Gran, which could be difficult.”
I phoned my class lecturer and told her my father had been killed in a freak accident. I was told that all the main lectures were over, and she would arrange notes on every lecture I missed.
Mrs Boyd had my number; she told me she would message me next week to arrange a meeting.
I phoned Gran telling her I had to see my Mum and had to stay at home tonight, but I could give her a good fuck now if she wanted.
Gran replied, “I’m playing with my cunt as we speak. You get excited when I use the cunt word, my cunt’s hungry for your cock.
“Jack, my clit’s so big, I’m playing with it, it feels so good, I’ll play with myself until you get here.
“My legs are spread wide for you. My hot cunt will be ready for your tongue and your magnificent cock.”
Gran was lying on top of her bed, legs spread wide open, playing with her huge clit.
Gran looked gorgeous as I undressed. My penis was erect.
Gran smiled and said, “Jack, has something happened? If something has, then slide your cock inside me. I always feel secure when your cock is inside my cunt.”
I lay down beside Gran. We kissed tenderly and affectionately for several minutes,
I had been fingering Gran’s huge clit as we kissed. Gran was soaked.
I went down on her, sucking her massive clit as I finger-fucked her hot cunt. I loved the taste of her cum.
She was ready for me. I wanted to look into Gran’s eyes when I told her. I slid my cock inside her in the missionary position.
Gran said, “That feels wonderful, fill my cunt as you tell me, you can tell me anything now, darling.”
I was now getting into a rhythm. Gran was gripping my cock beautifully.
I said, “Gran, I have some unfortunate news to tell you. There’s been an unfortunate accident.”
Gran interrupted me, she said, “Darling, if it’s about your father, I already know. It’s frightening that this could happen. After we are finished here, you must be with your mother.
“She needs you so much now. You must tell her that if she needs anything, she must let me know.
“I’m so sorry to lose my son, but I still have my daughter and grandson to give me pleasure, fuck me hard and deep, and I will be fine.”
I kissed Gran as I rode her.
I asked, “Gran, how do you know, Mum phoned me three minutes before I phoned you?”
Gran replied, “Jack, Jill, your father’s PA is a good friend of mine. She was a Paralegal. She has an excellent legal mind.
“After your grandfather died, your father was not ready to run the business. Your father was a lawyer but had no experience in commerce.
“I appointed Jill as your father’s PA. She is the reason the company has been so profitable. You have even complimented Jill on her legal knowledge when she tutors you.
“Jack, I will be honest with you, I visit Jill once a month to hear what’s going on in the company, and we are lovers.
“You must keep friendly with Jill, she’s in her late forties, a year younger than your mother.
“Your Mum visits Jill more often than I do. Your mother and father did not have a happy marriage.
“You are the only good thing that came out of the marriage. I’ve been honest with you, fuck me, then help your Mum.
“Jill is helping and will probably be with her when you arrive. I love you, Jack. You will inherit everything.”
An hour later, I left Gran. She was glowing. I had showered before I left. I phoned Mum ten minutes before I arrived to let her know when I would be coming.
Mum told me that Jill was with her. They had been going over his father’s private papers, which were kept in the safe in their home.
I arrived home and went into my father’s study, where Mum and Jill had Dad’s will all over his desk.
I hugged Mum and said, “This is a great shock, I thought while driving up that I’ll go to the mortuary for the identification, that will save you going.”
