Pam showed me Tom's selfie, "Tom's a good-looking young man. I knew the picture would excite him; my cock stiffened when I took the pictures. Do you quietly want to let him know you could be available?"   

"Darling, let's go home. Mummy will make you stiff again, and we can talk about it in bed. The thought of it excites me, but I'm so happy and satisfied with you. There's no way I want to give you up. I'm still tingling from this morning, and I want the same again. After that, we can think how we reply."   

As I paid the bill, I felt sure Pam was interested in her son, Tom. Maybe she'd be interested in a double penetration from both of us? Pam was the only woman I've ever had who could completely satisfy me. There was something so special about her I didn't want to lose her.   

We walked home. Barry, you're making me so horny now. All I want is the king; I had my arm around Pam fondling her massive right tit. I've decided to reach out to Tom and show my appreciation for the compliment. I'd love for him to visit, but he must assure me he'll keep any contact with me a secret from his father. I'll also tell him you're my lover. Are you ok with that? I'll let you read it before I send it."   

In the apartment, Pam stripped naked, and so did I; she lay on her bed with her legs spread as she typed her reply to Tom. I went down on her. I was sucking her huge clit as she wrote. She was now pushing her pussy hard against my mouth.   

Pam let me read what she'd written, "Dear Tom, thank you so much for your lovely birthday message. I was so happy when I read it. I'm also glad you liked the picture. You're more than welcome to come and visit me, but please promise me that you'll never tell your father about any contact you have with me. Barry and I are now in a relationship. He spends a lot of nights in my apartment. Please never tell your father about him. We are going to France on Friday for a nine-day trip. I'm looking forward to our journey as I love being with a younger man. If you promise me, you'll never tell your father anything about me that would make me so happy. If I can trust you, we can be more open in our messages. Another condition: any pictures I send you are for your eyes only. 

I am looking forward to hearing from you. All my love, Mum xx."   

I smiled when I read it, "Mummy's naughty. When he replies, you could tease him a bit more by sending the kimono picture. You should also ask him about any relationships he's had. I'm sure he'll reply soon."   

"I have the feeling he will, too. The kimono picture is a good idea. I also bought a very skimpy bikini; my big melons spill out of the top. There's not much to the bottom. It's a tight-fitting design that shows my camel toe to perfection. Let me give you a nice gobble, and then I want a hard birthday fuck. I want you to know that Mummy enjoyed her birthday with you."   

Pam gave me a great gobble. My cock was dripping with her saliva. She could do some incredible things with her lips and tongue. When she gobbled, she would always cum at least once. The other thing I'd noticed was when she sucked cock, it aroused her a lot. She told me she wanted a hard and deep doggy-style ride. That's what she got. She had three massive orgasms; I had only one, but it was a good one. I spurted powerfully six times against her cervix. We fell asleep in each other's arms.   

The next morning, we made love again, showered, and had breakfast. Pam said, "I should check my mobile; I wonder if he's replied?"   

She went to the bedroom and came back with a smile on her face, "I think he's interested. Let me reread it so I'll know the best way to reply."   

Pam reread it and handed me her smartphone, "Have a read and tell me what you think?"   

"Dear Mum, thank you so much for the invitation. Your tempting offer is too good to resist; I would love to take you up on it. I would love to spend time with you and get to know you better. I hardly speak to Dad. He spends no time with me. He wanted me to join his business, as I wanted to be independent. I told him I wanted to study dentistry. I know I'll get good grades in my exams."   

"My word is my bond. I promise you that anything we do together, Dad will know nothing about it. There is a small group from the school that's taking a European tour during the holidays. They'll be away for ten weeks. I'll tell you a little secret, but it comes with conditions. You never tell Dad. As you know, Dad has an apartment in Chelsea. It's twenty minutes from my school. I occasionally go there on weekends. One of Dad's girlfriends is usually there. He's got a lot of girlfriends. In the last six months, I've had several of Dad's girlfriends. Suppose I ask one of them to suggest that I want to go on a school trip to Europe. I'm sure he'll finance it. I could spend ten weeks with you during the summer. If you like this idea, please let me know as soon as possible, as I need to get one girl to do special treats for him so he'll agree."   

"If this works out, I'm sure it will, as the only thing that Dad and I have in common is we both like big tits. If things work out between us during the summer, could I apply to a Dental College in your city? Let me know if you'd like me to go on the European trip to your apartment. Looking forward to your reply. All my love, Tom xx."   

I smiled at Pam, "I think he's more than interested. He's opening up; I like his style. He's resourceful, like his Mum. We could give him a summer job in the centre. You'll have to flirt with him and also tell him how good you feel when you're around me. Let him know he can't have exclusive rights with you."   

Pam asked me to make her a coffee, and then she started typing. Ten minutes later, she let me read her reply.   

"My darling Tom, ten weeks would be wonderful. Get your Dad's girlfriend to say that the European trip would be an exciting experience for you. Can I ask how old his girlfriends are and does he have many? I haven't told Barry that I've invited you. Don't worry, I'll do something special for him. I'll tell him I haven't seen you in over six years, and it would be wonderful if you could come and spend some time with me. I need to go to work. Write soon. All my love, Mum xxx."   

I laughed when I read Pam's reply. It would be an exciting experience when his Mummy fucked him, "Mummy, I think you'll have two cocks to service this summer. Please tell me what special things you'll be doing to me to get my approval?"   

Pam smiled and said, "You'll see tonight how hard Mummy will work to pleasure you. I get aroused thinking I can have Tom. Now I will have to do some packing for France, as we will be leaving in three days. I've one more appointment to make, and that's all the appointments made."   

We went to the centre in two cars. Everyone knew Pam was my Assistant. It was well received, as Pam was an intelligent, well-liked woman. Sally winked at me when I saw her at reception. She did this when she'd sent me a message. In the Bistro, I checked, "Is ten this morning good for you? I hear you're going to France on Friday, so I want a very special one this morning."   

I replied with two thumbs-up signs. I finished my coffee and went to my office, as I had several calls to make. Sally was hot when I got to her house. She didn't mention Pam; I had the feeling she knew what was happening but was happy I was with her now.   

I made Sally cum four times in the two hours I was with her. As I left, Sally said, "Barry, have a great time in France. I think the wine idea is a super idea. I'll be wanting to see you as soon as you get back."   

I checked my phone. Tom had replied to Pam, and Pam had replied to him. She had attached the Kimono picture in her reply.   

"Dear Mum, you do not know how much I'd love to spend the ten weeks with you this summer. I've got things going at this end now. Dad is in London today. As soon as I hear anything, I'll let you know."   

"Age of Dad's girlfriends? I prefer the older ones. They are two in their late twenties. Both of them know how to give a man pleasure. The younger ones have only big tits and no experience. I look at your gorgeous birthday picture often. As soon as I hear anything, I'll let you know. All my love, Tom xxx."   

Pam's reply, "Dear Tom, thanks for your message. I think you appreciate an older woman. I appreciate a younger man. How did you get involved with your Dad's girlfriends? As soon as I know you're coming, I'll start working on Barry, as I have some time to do that during our stay in France. I've attached a picture of me in a kimono. When you're here, you'll see that I dress to please Barry in the house. I have several of these silk kimonos. The feel of silk against my naked body excites me. I hope you like the picture. I'm having a busy day at the centre. Write when you can. All my love, Mum xxx."   

I smiled and thought of Tom having an instant erection when he saw Pam's gorgeous body, and she was showing lots of it in the kimono picture. My phone beeped; I had two messages. Tom had replied to Pam, and Pam had replied to Tom. Things were moving.   

"My darling Mum, thank you so much for trusting me in sending that gorgeous picture to me. I'll treasure it forever. You have a beautiful, voluptuous body. Barry is so lucky to have you and for you to dress to please him in this way. I look forward to more pictures like this, as you look so naturally beautiful."   

"Mum, I feel so awkward in writing this to you. I'm not on an ego trip, but when you read this, you'll understand why Dad's girlfriends can't get enough of me. It's with the utmost humility I inform you at school, they call me 'Tom Three Legs,' I have a massive hunk of meat hanging between my legs."    

"Just after my eighteenth birthday, I was staying in Dad's apartment for the weekend. Dad's oldest girlfriend was there. We had some wine. One thing led to another. As we kissed, she let me fondle her massive, juicy tits. She gave me a massive erection. I'd never felt my cock so hard in all my life."   

"She stripped naked and asked me to do the same. She whimpered when she saw my cock. I won't go into details, but she'd never had a cock as big as mine. That weekend was my first time. I had so much sex. On Monday morning, when I left Dad's apartment, I knew a lot more about sex than I did on Friday evening. She asked for my number. If Dad wasn't in London at the weekends, I was in his apartment. Word soon got about. I was doing threesomes regularly with Dad's girlfriends."   

"Mum, I hope I haven't offended you by this reply. You asked me a question. I gave you an honest, truthful answer. Did you want me to reply that they found me a fun person to be around? Now I'll worry about this. One positive thing to come out of this. Your kimono picture gave me a bigger erection than I had on that Friday night. Write soon. I love you and want to kiss you everywhere. Tom xxx."   

"My darling Tom, thank you for your honesty. I appreciate it. Barry is also well-endowed, and I love being with him for that reason. I dress and do things for him to make him hard. I'd like you to call me Pam when you write. A Mum shouldn't be asking this of her son. I'd love it if you sent me a dick picture of your prince. No words, only the picture. In France, I'll go topless in my bikini. I'll send that to you with no words."   

"Are you dating anyone, or do you just see Dad's girlfriends just for sex? When was the last time you had sex? I love to kiss all over, too. All my love, Pam xxx."   

I loved Pam's reply and the subtle way she asked for a dick pic. I thought of Pam and the tight bikini bottom, which showed her Camel's toe perfectly. I'd take my time taking that picture. My phone beeped again.   

Tom's first reply was a dick pic. It was big. Without seeing it in real life, I had the feeling I was slightly bigger. Pam hadn't as yet replied to it. Tom's following message was brief, "Pam, my last six months have been nonstop sex. How open-minded are you? Do you want a full and honest account? I hope you liked the picture. I'm thinking about you differently now. All my love. Tom xxx."   

I couldn't believe how quickly this was changing. Pam sent me her reply. "Tom, I'm very open-minded. Nothing you have written so far has offended me. I think we both have a high libido. I doubt there's anything you've done that I haven't done. Please be open and honest with me. I won't be able to give you exclusive rights to me. The thought of sharing you with Barry excites me so much. I'm now thinking of you differently. All my love, Pam xxx."   

It was an hour later that Tom replied; Tom was sincere now, "Thanks, Pam; in the last six months, there's not much I haven't done. Soon, I was having threesomes regularly with two of his girlfriends. Dad could satisfy none of them. One girl wanted a threesome with her mother and me. The mother was in her early fifties. I loved having her. She was better in bed than her daughter."   

"The next development was I had a friend at school. He's a touch smaller than me, but when he fucked you, you knew you had been fucked. The girls loved us both. I brought another guy from school. Three was one too many. When they have a cock in their mouth, they can't talk dirty. We did a lot of Double Penetration. All the girls loved this."   

"My learning experience has been excellent. Holding back comes naturally to me. No way am I a two-minute man, that's for sure. I also reload in minutes. I'm not dating anyone. When I start university, I can easily continue with what I'm doing if I stay in Dad's apartment and attend a London university."   

"Pam, the most important thing in my life at the moment is the possibility of spending ten weeks with you this summer. I want to get to know you. If things go the way I think they could, then I'd be prepared to apply for the university in your city."   

"Darling, I don't want exclusive rights for you, and you wouldn't have exclusive rights for me. I get so aroused when I get close to an available, busty, mature woman. I'll soon know if my father will finance my trip to Europe. I'm thinking now I want to spend the ten weeks with you. Please write soon. I'm thinking about you. All my love, Tom xxx."   

It surprised me how fast things were moving. Pam loved to have a threesome with two guys. This was going to get her thinking. I was also thinking that Sally, Mum and Gran, Ava and Mona, Tina and Lucy all loved a gigantic cock. I enjoyed being with Pam. We were both so relaxed with each other. The sex we now had was incredible.    

My big problem was how would I explain to Pam that I was fucking all these busty women, and how would she react? Sally had been my introduction to mature women, and what an introduction it was. Gran and Mum had followed. They both enjoyed what I was giving them. The rest were all part of the business. They all wanted my cock. I had no problem giving it to them as doing this helped the company. Hopefully, Pam, my assistant, will see this.   

My phone beeped, and my heart missed a beat; Pam had sent me her reply to Tom, "My darling Tom, we're so alike. It arouses me to have a threesome with two males. I agree with you, there are too many. I've been open and honest with Barry. I've told him I enjoy a threesome. When we're in France, I'll quietly suggest having a threesome with Barry and you. I enjoy being with Barry, as he satisfies me sexually in every way."   

"During the ten weeks during the summer, I will ask Barry to give you a summer job at the centre....
