The next days flew by. Jack told Mum about Jo, and Mum agreed Jo could do a lot for Jack. Mum took several pictures of Jack’s magnificent cock.
Jo was more than impressed and sent pictures of her huge clit. Mum realised Jo was a patient at her Clinic. She was liked a lot by her mum. Jo, though a lovely person, was unhappily married, Mum informed Jack.
The next day, Gran came to Mum’s. The sex was terrific, Mum and Gran were excellent together, they were both filthy in bed.
The next day, Val came down, and Jack satisfied the three of them in bed. Mum had given Jack some Viagra and some Cialis, a quarter of a Cialis two hours before sex.
A quarter of a Viagra and Jack’s cock was rock hard for eight hours, he was still hard when he fell asleep, Mum told him it was still hard in the morning when she sucked him to wake him up.
Gran and Val were spending a lot of time at Mum’s house. On Friday night, Jill was invited for dinner. It was a fantastic night. Jill was so hot in bed that she added to everyone’s experience.
Jo and Jack were replying to each other’s messages. Jo was honest, and Jack respected her for this.
Jo had seen the obituary for Jack’s dad in the newspaper. She wrote to Jack to ask if she could attend, as she wanted to pay her respects to Jack and his mother.
Jack asked his Mum over dinner on Friday night when everyone was there.
Mum said, “No problem, Jo’s a lovely girl, invite her back to the funeral party, it’s better if you wait until Sunday afternoon with her, as it would be better not to show your full hand until later.”
Gran, Val and Jill were all curious, but Jack and his Mum said nothing. The funeral was proper. All Jack’s girls looked so sexy in black.
Jo looked stunning in a risqué black outfit and at least three-inch heels. Jack had invited Jo to the party.
At the reception, Mum took the initiative and sat with Jo, Gran, Val and Jill, along with Jack, at the same table.
They all chatted freely together. They were all impressed with Jo. Jo was entirely at ease with all of them.
When Jo left, they all gave Jo a hug and a kiss on the cheek. When Jack hugged her and kissed her cheek.
Jo whispered, “I can’t wait until tomorrow, I’ll make it so special for you. I’m impressed. Beautiful women surround you.”
They got back to Mum’s house just after three. Jack had taken Mum’s medication. Mum had told him to take it. He was primed and ready for action.
Jack had made all four of them orgasm, they showered and went out for a Chinese meal at seven. When they got home, Jack repeated the procedure, and he made them all cum.
Gran, Jack and Mum went to Mum’s bedroom while Val and Jill went to Jack’s bedroom.
Gran and Mum wanted more, which Jack gave them. Mum was eating at Gran’s pussy when Jack was fucking Mum. Gran was eating at Mum’s pussy when Jack was fucking Gran.
As they lay in bed before they fell asleep, Gran said, “Jack, you must cultivate Jo. She can do so much for you. She is going over some lectures with you tomorrow.
“I sensed she would do more than that with you. You should seize the moment, as she can do so much for you.
“You must do it, as once she has your magnificent cock inside her hungry cunt, you will have a friend for life.”
The next morning was very relaxed. They got up for breakfast at noon. Jack had fucked Gran and Mum.
In the shower, Mum said, “Jack, Jo is taking her husband to the Airport this morning, he’s going to Portugal on a golfing holiday with friends.
“I’m sure the opportunity will arise, take an overnight bag and go back to University on Monday morning. This week, try to spend as much time as you can with Jo.
“Gran and I will stay at Gran’s. By Wednesday, we will invite Jo out for dinner. Keep taking your medication at the times I’ve told you.
“I’ll check tomorrow if Jo is on the pill. From memory, I don’t think she is. Jo is healthy, but at her age, it would be difficult for her to get pregnant.
“I’ll go to the Clinic this afternoon and check. If she isn’t, then you have got to bring it up with her.”
Jack arrived at Jo’s villa. It was very grand with a long driveway. As he walked to the front door, it opened.
Jo was standing there wearing a blouse and a miniskirt and three-inch heels. She looked stunning.
Jack took her in his arms, and they tongue kissed, Their kisses were slow and deliberate, with lots of tenderness and affection.
Jack could feel the weight of her massive breasts on his chest. It felt so good.
Jo said, “I feel the same as you, but I want to go over the lectures with you first, then we can have some fun. Have you had lunch? I can make you something?”
Jack thanked her and said he had a late brunch. They went into the dining room. Jo had all her papers laid out. Jack was impressed.
She had her lecture notes, and the essential items were highlighted in yellow. These were the parts that would appear on the exam paper.
For the next hour, Jo went over everything with Jack, telling him what to remember and what was vital for him to know. She explained everything to him. Jack had learned a lot, and both of them knew it.
When they finished, Jo left her papers on the table.
She said, “Jack, I want to have an hour with you every day this week, then you will see the benefit. Let’s go into the lounge, I have some nice Chablis in the fridge, would you like a glass?”
Jack smiled and said, “I’d love a glass, I’m feeling a little nervous.”
Jo got a bottle of Premier Cru Chablis, which Jack opened and poured into two glasses. Jo put some ice into a wine cooler, and they went into the lounge.
Jack loved the way Jo’s hips moved as she walked. They sat on the sofa together. Jo’s skirt had moved up her thigh, the top of her self-supporting stockings, and some of her naked leg was visible.
Jo then offered her glass to clink with Jack’s.
Jo said, “Jack, I’m so happy that we are here today. I would like us both to strip naked, then we can kiss and caress as we sip our wine. I wish us both happiness, cheers.”
