Donkey Dicked Clare

I am a 58m widower this adventure takes place when I was 26 my fiancé Clare was 27 and my best man John was 25.
Clare and I were house sitting for a friend and invited John over for the weekend, hiking using the pool, BBQ
Friday night Clare was very aroused when we went to our bedroom, her panties were soaked when I asked she said she was just really turned on and wanted to fuck.
I went to go down on her, she looked at me and said later, just FUCK ME! I did she was more vocal than usual and I had hoped that John didn’t hear us, (John was single for a long time at this point)
After I blew my load in Clare and she had several squirting orgasms I got to go down on her and clean her up to another orgasm.
Saturday I woke up to an empty bed room that reeked of sweat and cum, I showed and went downstairs, John and Clare were talking as I walked in, and a I poured myself a cup of coffee, Clare says we kept poor John up all night with our noise! I coughed a mouthful of coffee through my nose, using a towel I cleaned up and muttered an apology. Feeling bad for my single friend,
Clare said, he got really hard and jerked off. Didn’t you John?
He admitted he did. That was the end I thought, we went for a hike showed after and start around the pool, John went to get some drinks and Clare said “oh my god his cock is huge I can see the buldge in his shorts!”
I said yeah he is with a bit of a chuckle we called him donkey dick in high school track.
