I’ve (47F) been having regular sex with my son’s friend (19M) for a month. My son doesn’t know. [FM]

I mostly just lurk on Reddit but finally I have a story worth telling so I made a throwaway account.

Just as a visual aid, I am 5’4, blonde and D-cup. I do exercises at home to keep fit. Prior to lockdown I was going to the gym regularly, so I am quite physically fit for my age. I have a flat tummy and my bum is bigger than it has ever been before.

My son (who is 20 now) has been having his school friends over at our house since he was young, so I know his friends and their families well. I’m friends with them on Facebook, and recently I finally got around to making an Instagram account, and I followed a few of the people I know, including my son’s friends.

My son is at university in another part of the country now, but a few of his school friends still live in the local area. Some of them attend a local university, and some of them are working. One of them has grown into a very charming young man. He’s tall, I would guess maybe 6’2, he’s a couple inches taller than my son. He’s also polite and always made a point to greet me whenever he was over at my house.
