First time with a couple [MFM]

The last story I shared had us ending with Sally and John reaching out to me and us clearly going to get together at some point.
We exchanged several texts back and forth. Some pictures, some dirty talk, but mainly planning and bouncing ideas off of each other about our inevitable meeting. They made it clear that at least our first meeting or two would need to be someplace more neutral, a bar or something similar, but that they would happily have me over to their house when we were comfortable with each other. I was more comfortable with this also and we went back and forth about where we could get together.

My Gym Experience [MM]

At this point in my life I am 24-25, brown hair, blue eyes, 5’7 135-140lbs. I have a 7.5ish circumcised nicely shaped cock, that is girthy and gets ROCK hard. My occasional fantasy of getting naked/showing off my cock in public had turned into a full on obsession, and one of my ‘regular’ friends ‘Mike’ suggested that I try showing off for him in a gym locker room. I have no gym membership, so this is something I had never tried, but was open to. His gym apparently allows a guest pass option and has a bit of a reputation for like-minded ‘cruisers’ so we try there.

I have my easy access gym shorts and a slim fitting tee on, Mike (60s a little taller than me, grey hair horseshoe/balding) gets us in through the entry gate and suggests we drop stuff off at a locker and head to a distant treadmill/equivalent. (We didnt want to be obviously only there for the locker room.)

My first adventure in the park behind my old apartment [mm]

Hello, this is the first meeting I had in the park behind my old apartment. I hope you enjoy.
After I moved into this apartment I knew I was going to end up naked in the park behind it. The park is this big open space with hills and several pavilions and playgrounds scattered about, but more importantly were the walking trails. On all sides of the park were trees, and to the back was a full on forest complete with several walking trail entrances. On the outside of each entrance was a park bench. This is where our story starts.

I got on an online message board to find locals and found an older guy into outdoor play, so we met up at the park. I am 24 in this story. 5’7 145, a smaller build but I wear it well. Brown hair blue eyes, fit, runner. I LOVE getting naked for others, I even more enjoy having the opportunity to cum for an audience. This guy was interested in letting me strip naked and figuring out what would happen from then on. So I walk up to him on the bench and identify myself by the screenname on the message board.
