San Diego Fun

I didn't know San Diego CA was kind of a mecca for gay people. I am a 42 yr old gay guy. My nephew (Brad) came out as gay at 18 and move to San Diego to go to school. Last week I had some business in CA and decided to slide through San Diego and see him for a couple of days.
My last day there Brad confided something to me that was surprising. He said he was a member of a local gay swingers group and there was a party that night. Brad invited me to attend if I wanted. I was curious so I said OK.
It was a nice group of guys. Of course at 42 I was the old guy in the room. All of the boys were my nephews age or a little older. Brad was one of the youngest at 20 and most were mid 20's. I counted 12 boys and I made the lucky 13. One guy spoke up and called everyone's attention. He took a hat around the room and all the boys wrote their name on a small piece of paper and put it in the hat. Brad told me I was exempt as a guest. I had no idea what was going on. He drew out 4 names as the crowd cheered. The 4 boys picked walked to the middle of the room and to my surprise they stripped down naked. They all got down on the floor. Boys around the room started stripping down and lining up. Brad explained that the 4 boys were going to spend 2 full hours being total bottoms and pleasing everyone in the room. I was still fascinated and stood there with my clothes on watching. The 4 boys were amazing! They were sucking every cock put in their face and boys were taking turns fucking their cute asses. Brad was joining in and I was impressed at his cute body. After nearly an hour Brad took a break. He led one of the bottom boys over to me. Brad helped the boy take off my pants and Brad took hold of my dick and fed it into the boys mouth. It felt great and not to mention dirty having Brad touch my dick! I joined in fully from there.
After 2 hours things switched up. Another drawing put 4 new boys on the bottom. Brad never had his name drawn so he spent the evening as a top. We felt each others ass and dick up a few times during the evening but didn't have sex with each other. I wonder if his name had been drawn would I have had the nerve to actually fuck him. I think I would have invited him back to my hotel room after the party but we had both pretty well used ourselves up. I managed to get off twice at the party and I know Brad didn't hold back.
Maybe next time...
