Jack fucked Gran after the phone call to Val. Gran had fucked Jack in the cowgirl position. She gave a great ride. Jack fucked Gran on Wednesday morning before breakfast.
Jack had left for university. Gran had told him she would update him on Val as soon as Su had told her what Val enjoyed.
Just after three, Jack’s phone rang. It was Gran who told Jack that Su was impressed with Val. Su had transformed Val. Her hair colour was now blond, like Gran’s.
Her cunt was now smooth. Val was hot. Su had made her cum twice. Gran had paid for three outfits for Val. Val had bought another four for herself.
Gran said that this was a good sign as Val was now taking an interest in how she looked. Su had told Gran that she had brought Val off twice after the waxing.
Gran said, “Jack, after I had spoken with Su, I then went to Val’s apartment. She’s been transformed. She’s now blond, and it really suits her.
“We had a glass or two of wine, then Val told me that Su had made her cum twice, Val told me that was the first time that a woman had made her cum.
“She had enjoyed it, she told me she was now bi-curious. To cut a long story short, Val loves sex with a woman. I had sex with my daughter this afternoon, and we both loved it.
“Val is a very sexy woman, you’re going to love her big tits and her beautiful cunt tonight. I’ve told her about you, how I took your virginity.
“How you took my ass virginity, I’ll never forget that. I was thinking tonight, the theatre finishes at nine-thirty.
“Val and I will come back to my house. We can have a few drinks and order an Indian takeaway, how do you feel about that?”
I replied, “It sounds good to me, it will be after nine before I’m home from the rugby training. I’ll wear a towelling bathrobe and wait for you.”
“I can’t believe that I’m going to fuck a mother and a daughter tonight, that’s making my cock hard.”
Gran answered, “That’s making me so hot, too. Val is a good fuck. She’s like me and has a big clit.
“I loved her opening her legs wide for me as I sucked her clit. Jack, don’t you be wanking, you will have a lot of fucking to do tonight.”
Jack replied, “Gran, I won’t, I am so looking forward to it. Imagine a threesome with my Gran and her daughter.”
Gran spoke quietly and said, “Jack, I’m playing with my cunt this now, you like it when I say cunt, don’t you?
“I wish you were here now to lick it and fuck it. It’s so good, my clit’s so fucking hard.
“I’m playing with it, and it feels so nice, think about your Gran and her daughter with their legs wide open for you.
“Both their cunts are swollen and hungry for your tongue and your magnificent cock. Tonight will be special, darling. See you at nine-thirty, I love you.”
I replied, “I love you too.”
I finished the research I was doing in the university library and went for a fish supper. I went for my rugby training.
It was a hard session, but I felt good after showering. A lot of the guys stared at my massive, flaccid cock, it was easily the biggest cock in the shower room.
Paul, Jack’s friend, was marginally smaller.
I got home. I put on the aftershave that Gran liked around his cock and balls, and around his face and chest.
I opened a bottle of Champagne, put it in an ice bucket, placed it on a tray with two spare glasses, and went into the lounge, where I waited for Gran and Val to arrive.
They arrived just after nine-thirty, and they both looked gorgeous. Gran gave me a long, passionate kiss.
Gran whispered, “Val and I are both so smooth between our legs, would you like to see? Then we can have some fun before ordering Indian food? Jack, you smell so good.”
Val was smiling. She looked the best I had ever seen her. I took her in my arms and said as we cuddled.
“Aunt Val, you look gorgeous. Everything about how you look is perfect. I love you as a blond.”
Aunt Val replied, “Jack, thank you for the kind words. If you like, call me Val, but when we are very intimate, it would excite me if you called me Aunt.”
I pulled her close, then our mouths met, our tongues exploring each other’s mouths.
Gran was stripping. She was wearing a crotchless bodysuit, which pushed her massive tits up.
Gran said, “It’s good to see the two of you getting on. Let’s all get naked, and the party can begin.”
Gran was feeling my hard cock, she said, “Val, Jack’s cock is so stiff, he will do you first as Mummy has already had him today.
“My cunt is wet, it really excites me to know that I’m going to share a magnificent cock with my daughter, Val. Is your cunt wet?”
Gran was now helping Val undress. She was now only wearing a crotch less bodysuit with no panties and self-supporting stockings.
I was now naked, my cock was massive and looked so impressive, Gran and Val couldn’t take their eyes off it.
Gran said, “Jack’s so big and hard, Val, I’m so excited at seeing this magnificent cock sliding inside your beautiful sex slit. Let’s take our time, I’m so fucking horny.”
Val was now sucking on my cock. She was good. She was taking my full length.
Gran went down to level with Val’s mouth and my cock. Gran’s breasts were bouncing everywhere.
Gran whispered, “Val, let me taste his cock with your tongue.”
Gran and her daughter’s tongues were in and out of each other’s mouths.
