Gran had told Barry that all she would wear would be her butt plug. From the way Gran had spoken on the phone, Barry knew she was horny.
Barry arrived at Gran’s. Barry checked his phone. Mum had sent a selection of pictures and two videos. The videos of her were excellent. She had a beautiful body. The photos showed Mum posing in front of the full-length mirror in her bedroom.
Mum was sitting on the edge of her bed with her legs open, her thumb and index finger were spreading her thick cunt lips open. Mum was a very sexy woman. As Barry watched the two videos. He felt his cock stiffen. She gave him a peep show on the videos.
The way she was fingering her pussy was so sensual under the subject title of For Your Eyes Only.
The message read, “Dear Barry, thanks for coming down today. I’m so happy that we are both in agreement to do this project together. I’ve willingly sent the pictures and two videos. I want you to understand that, as well as being your Mum, I’m also a woman who has needs and desires.”
“There are no men in my life; I have several girlfriends and patients with whom I have sex. After you left, Carol gave me some contraceptive pills. I still have my period. It will be safe for us to make love on Tuesday evening when I get home. I love you, Mum, xx.”
Barry went to Gran’s. She was in the kitchen naked with the butt plug protruding from her ass. They kissed lovingly for a couple of minutes.
Barry said, “Gran, I’m going to have a quick shower before dinner. Is that okay with you?”
Gran told him the potatoes would be ready in another twenty minutes. Barry went to the bathroom. He didn’t use Gran’s bathroom. He looked at Mum’s pictures. His penis was stiff. It looked so impressive. He took several photographs. He attached them to the message he sent to Mum.
“Dear Mum, thank you for your pictures and videos. The attached photos show the consequences they had for me. I hope my pictures give you the same excitement that your pictures gave me.”
“I will be home around five on Tuesday afternoon. Is there anything that you need for coming home? The fridge is empty. I love you, Barry. xx.”
The meal was beautiful. Barry’s cock was rock hard throughout the meal. He wondered if this was because of Mum. He was also very aroused by being close to Gran over dinner.
Gran asked Barry if he would give her a titty fuck, then give her a mouth fuck. She also wanted him to ass-fuck her.
Gran had it all planned. How she would video it, the positions she’d have to get into to do it. They went into the lounge. Gran lay on the couch, her head leaning over the cushions.
Her legs were on the back cushions. She got Barry to put his cock between her massive tits. As Barry did this, he realised that Mum’s tits were as big as Gran’s. The head of Barry’s cock was facing the back cushions of the couch.
As he rode her tits. He felt Gran’s finger rimming his ass. It was a wonderful feeling. Gran gave Barry the camera so he could video everything. Gran was purring with pleasure as he titty fucked her.
A couple of minutes later, Gran asked Barry to lift himself. She then positioned her head and throat so that she could take Barry’s full length. Barry quickly realised what was happening; he angled his cock to suit how Gran had positioned her head. He then fucked her mouth.
The head of his cock is banging against the walls of Gran’s throat. Occasionally, she would gag, but she overcame it by breathing through her nose. All the time, Barry was filming this as he rode her mouth, Gran was fingering her cunt with two fingers.
Barry then sat on the couch. Gran got on top of him in the reverse cowgirl position. She pulled her butt plug out. She slipped Barry’s stiff cock up her ass and rode him. Ten minutes later, she had her third vaginal orgasm.
Gran’s whole body was shaking with this one. She soon composed herself, then went on top of Barry in the cowgirl position. As she rode him, she looked lovingly into Barry’s eyes. Gran had such a contented look on her face.
They both climaxed within seconds of each other. Gran was trembling as she came. She leaned down, and they kissed so affectionately for several minutes. Gran was holding Barry’s cock inside her with her powerful pussy muscles.
Gran said, “That was wonderful, Barry; I’ve never been so happy in all my life. When is Babs coming home?”
“On Tuesday afternoon, the Hotel and Spa is a good idea. It will be both Mum’s and my future. The Hotel that I visited was so busy. It’s only for ladies. No men are allowed in the building. Because I’m Mum’s son, I was allowed in. I was so impressed with it.”
Barry then told her about the green bracelets, how the women were all swimming naked. They were all so friendly and talkative. They all looked so relaxed there.
Gran said, “It sounds like an exciting idea. I know little about Babs’s finances. If she needs money, I’ll give it to you and her.”
The next morning, Gran only wore an apron as she cooked breakfast.
Barry arrived at the University early. He checked his phone. Mum had replied.
“Dear Barry, what can I say? You have a magnificent cock; I have never seen one as big. I got very excited when I saw it. I met a lovely lady in the pool. She was wearing a green bracelet and flirting a lot with me.
“We had dinner together. I was thinking of your beautiful cock when I came in her mouth. I’m sure that she’ll be a client when we open our Hotel. I will go shopping on Tuesday afternoon when I get home.
“I had goulash for dinner this evening. I saw Carol. I think Carol likes you. She would love you if she knew about your magnificent cock. She gave me the recipe. Would you like a goulash on Tuesday evening?
“I have a meeting with Carol’s architect tomorrow morning. Carol is happy with him. We may use him if the distance is not too far for him. I know he will give us good advice. I will write tomorrow after I meet him. I’m looking forward to Tuesday. I love you, Mum, xx.”
Barry replied, “Thanks, Mum, goulash would be super. I’m looking forward to tomorrow too. I am a little nervous. I hope you have a great day. I love you, Barry xx.”
Barry’s day flew by. It was a full day. Mum had replied, saying that she liked the architect. He wanted to visit the site.
Mum had suggested Friday afternoon, knowing that Barry was free on Friday afternoons. The architect had suggested meeting at three in the afternoon. Barry was pleased about this. It meant that he could spend a couple of hours with Jo.
On Tuesday morning, Gran and Barry had a fantastic session. Gran knew it could be a few days before she could be with Barry again. She accepted this. She was so loving to him that morning. Barry left after breakfast. They kissed passionately before he left.
