Navigating Conversations on Relationships with Kids

No regrets. We're a MWC 62/60. We're both retired professionals. Mark is 62, handsome, about 5'11 average built. He has some medical issues and takes several medications. Sadly for both of us it has affected his ability in the bedroom. He can't maintain an erection, but luckily he still cum. I still enjoy relieving orally and occasionally he pleasures me with one of my toy's. It's not same as the real thing but we get by. I'm Sally,60. I'm about 5'7, a little chubby around 140. I'm about a 34-30-36, and neatly trimmed ☺️. We have two wonderful son's, both college graduates. Larry is 37, tall, handsome and doing well working in a large Manufacturing Company. Steve is 35, also tall, handsome and is a Highschool teacher and football coach. Raising them we were probably more shall we say progressive than most. We believed that they should learn more from us rather than dirty bathroom gossip. When they were teens we decided to start teaching about sex, about themselves and the basics. We sat them down and set what we thought were reasonable guidelines. We told them we knew at their age that masturbating was a normal thing. I told I didn't want to find any crusty socks under their mattress. We would prefer they use condoms and throw them away. If they didn't want to use them they could use my bras or panties from the hamper and put them back when they done. Nothing would said, the laundry had to done anyway. On occasion we would allow them to watch us have sex and we encouraged them to ask questions. They learned that it wasn't all about them. We could see it in eye's as they got older, they both wanted to participate. Neither of us, even knowing that, ever considered it. They were to young, and after all they were my son's. Over the years me and Mark would occasionally reminisce about it and the subject always went to What If?. I didn't want to hurt his feelings so I kept my thoughts to myself, but especially over the last few years since his problems, I had been thinking about it more and more 😔. I knew I shouldn't be, but I couldn't help myself. I mean yes I was 60, but I still had a very active sex drive. I tried to comfort myself in sucking his limp cock, and really tried to pretend him using toy's on me was satisfying. But deep down I think he knew that it wasn't 😩. The boy's usually come over on Saturday and took of all the lawn work for us, and anything else we needed. They would spend day with us, and the night. They usually went back to their own apartments on Sunday after lunch. It was always nice to see them and have them around. We lived in the country and didn't get much company. It was particularly hot that Saturday when they came over. It was unintentional, but I was wearing one of sundresses, long, very thin. I hadn't put on my bra or panties. Mark was in his shorts and tank top. The boy's showed up and changed into some shorts to work in the yard. I was fixing some lemonade watching out the window. Mark was sitting on the deck. I took the lemonade outside and Mark said why don't you sit down for awhile with me. Before I could sit down he looked at me, he smiled. You're not wearing any underwear Are you? I started blushing, Is that noticable 😳? He grinned, My God Sally it's okay, it's only family here. It's not like a bunch of strangers. You're fine. When Larry and Steve finally finished they came back to the deck and sat down. GOD they were so hot 🔥. Yes from the heat, but I mean 🔥. They were glistening with sweat, and I don't think they were wearing underwear. They had on loose fitting Nike shorts and I could see the impression of their cock's, which looked much bigger than I remembered 🙄. I tried not to stare, but I think they noticed. Mark kinda surprised me, he said can we talk to guy's about something. They said sure Dad. I had no idea where he was going, so I just sat there. We need your help, that is if you're willing. Part 2.
