Barry saw Gran on Wednesday afternoon. He told her that he was now sleeping with Mum.
Gran was genuinely happy about this. Gran asked if Barry had told her about her. Barry told her he had, that he wanted to be honest with Gran.
Barry said, “Gran, I’m also seeing Jo. I’ve been seeing Jo for a long time. She’s like you and Mum. I enjoy being with all three of you.”
Gran smiled and said, “I’m happy about that too, Jo’s a girlfriend of mine. She gives fantastic oral, but you do it better. Barry, I appreciate your honesty. I’ll have a word with Jo.”
“I have no problem sharing you with Jo. I’m sure that we could have threesomes with Jo. Now I need your cock. I’ve already lubed my ass for you.”
On Friday, before the Architect meeting, Barry met Jo at her house. Mum had told her about the proposed Spa and Hotel at the Clinic.
They talked about that after they had made love, Jo was excited about it. Barry then told her that he was sleeping with his Mum and Gran. Jo gave Barry a long, passionate kiss.
She said, “I’m so glad that you told me. Babs told me on Wednesday about the Hotel development and also about you. She adores your cock.
“She’s also happy about sharing you with your Gran and me. Barry, the Clinic provides significant relief to many women through stimulation.
“I’m also involved in that with private patients. I love giving oral sex. Babs has an excellent system in which she and the staff make money from private patients.
“I love to make a woman cum when I suck her clit. I think that you’ll make a lot of money from looking after the needs of our private patients who enjoy penetration. They will love your magnificent cock.”
Barry arrived at the Clinic just before three. Gary, the Architect, was sitting with Mum in one of the Consulting rooms.
Mum had given Gary a copy of the plans of the existing building. Then all three of them went on a tour of the Clinic and its grounds.
There was so much ground. They then went into the kitchen, where Mum made coffee. Over coffee, they discussed so many things. Gary was so professional. He came up with so many exciting ideas.
He felt that the area could support a fifty-bedroom Hotel.
One suggestion he had was to keep the Clinic and Mum’s apartment as they were, and to build the Spa and Hotel with a restaurant, lounges, and bedrooms, separate but connected to the Clinic.
This would ensure the Clinic could still operate while construction was underway.
He would return next Friday with detailed plans. On Monday, he would lodge an outline planning application for the proposed development. He would know within a week if it would be accepted.
On Sunday, Mum asked Gran over for dinner. Barry was pleased that she had done this.
Mum had phoned Gran after breakfast. She had been open with Gran, saying she could stay the night because her bed was big enough to take all three of us.
Barry was looking forward to tonight.
After lunch, Mum said, “Barry, I’m glad that Mum’s coming tonight. She sounded so happy when I asked her. During the week, I’ll invite Jo over, too. Jo is an excellent manager. I’m thinking of sending her down to Carol’s Hotel for training in hotel management.
“I don’t want to bring a stranger into this. Jo is very competent. She knows how the Clinic operates and the services we provide for our private patients. How do you feel about this?”
Barry replied, “That’s a great idea. You have an excellent staff at the Clinic. She would be an excellent manager.
“We should look for a wonderful cook. We must create very healthy menus. We should research foods that give a better sexual experience and performance.
“That could be a real winner. Our food must be good. I prefer a cook to have a chef.”
They went to bed on Sunday afternoon. Barry looked forward to seeing Gran tonight. He wondered how Gran would react to having Mum in the bed with them.
Gran arrived just before seven. She looked gorgeous. She was casually dressed, as were Barry and Mum. Barry hugged her, and they tongue-kissed. Barry sensed Gran was horny. The kissing lasted several seconds.
Mum said, “Mum, that looked so good, the two of you look so relaxed together. I am so happy that you are here, Mum.”
Mum then took Gran in her arms. They cuddled, then they tongue kissed. It looked so natural and erotic. They kissed for several minutes.
Mum said, “Mum, you’re a great kisser. I’ve got roast beef in the oven, the potatoes and vegetables are ready, so let’s eat now.
“Barry, I’ve some Champagne in the fridge, can you open a bottle?”
They ate in the kitchen; the meal was delicious. They all spoke so easily.
Gran said, “I’ve got butterflies in my stomach. I haven’t had that for years.”
Mum replied, “Mum, I’m excited too. Barry and I made love this afternoon. It would be fairer if you had him first tonight.”
Gran answered, “Thank you, Babs, I would love that. I want Barry to ass fuck me first. Do you have any lube in your bedroom?”
Mum replied, “Of course I have. Would you like me to lube you when we go to the bedroom?”
Gran smiled and said, “I would love that, but I want to lube you when Barry is ready for you?”
Mum got a fresh bottle of Champagne, and they went to the bedroom.
They were all naked within seconds. It was amazing how similar their bodies were.
Both had terrific bodies for their ages. Mum opened a tube of lube and left it on the bedside cabinet.
Barry sat on an armchair, sipping his Champagne, enjoying watching his Mum and Gran arousing each other.
They were both playing with each other’s tits. They tongue-kissed, but both their hands were exploring the other’s bodies.
