Discovery can be a wonderful event, especially when I learned that J.D. Manning and his boys Dylan and Canyon have something special in common with me and my boys Marcus and Dex. J.D. and I gently got to this understanding, learning that we are both gay while sitting outside talking in our backyard, drinking a couple of cocktails, both of us loving cocks and tails. While we were talking, the boys were playing ball in their wife-beater t-shirts and tight shorts, running, tackling, having a great time being boys. Our conversation drifted to that point when I saw J.D. adjusting his junk in his shorts while watching them play as I realized I was doing the same to myself. Although our discussion was in nuance, we both knew, and then confirmed. As time went on, J.D. and I became quite friendly with each other and even began a more romantic relationship, having sex that led to discussing our sons. J.D. talked with his boys as I did with mine, all agreeing that we wanted to bring the two families together and share. As all men know: ‘with women, sex has to be an experience, but with men, all we need is a place and a time’. So we set a time to meet at our house. The day we met, all six of two families were there ready for a gay incest son swap orgy. It began with the dads kissing their own sons, then the eldest sons moved over to start the fun. As all began to loosen up, another moved over to kiss and grope someone else from the other family. Then the clothes started coming off and different pairings formed, Dex and Dylan, Marcus and J.D., then Canyon with me. Once the clothes were all off, sucking could be seen and heard across the room and the sexual tension was rising. Dex latched onto Dylan and didn’t let go. While sucking, they moved into a sixty-nine position until Dex was ready to climb on top of Dylan and ride him. From the initial plunge downward, Dex’s moans were of pleasure. He did not stop and began riding Dylan hard and fast, not letting up. He wanted him and possibly has a new big brother to play with. Dylan was enjoying it so much that he was the first one to let loose and cum inside Dex.J.D. was giving a first class rim job to Marcus who was on all fours, moving around to kiss Dylan upside down while Dex was riding Dylan. Canyon had moved from kissing me to giving me a wonderful blow job. I’ll have to thank the man that taught him how to suck so well. Marcus moved over to Canyon after both sucking me for a moment, moved him around on the bed on all fours and dove in rimming him. Marcus moved up and got into position, pushing his big hard cock into Canyon. At the same time, Dex, who had not cum yet, got behind Marcus nudging the head of his dick on his hole. Marcus paused so that he could enter and then there was a three man chain fuck with Marcus in the middle. By this time all the pairings were facing the middle of the bed, bodies touching each other, kissing, nuzzling. I got my new special friend J.D. in there with them also on all fours, moved in behind him and thrust in. By this time, I had waited long enough and was ready to go to ‘pound town’ which I did, thrusting in and fucking him hard until I put a load of baby-boy makers deep in his hole. The trio in front of us was copulating at a slower pace. Marcus was balls deep into Canyon’s ass and the first to have his orgasm. Then Dex doubled down fucking Marcus harder, then injecting his load. After the chain decoupled, Marcus bent down and sucked out some of his own cum from Canyon’s hole, moved up and shared it with him in a kiss. The afterglow was wonderful. All six of us laid down, arms, legs, bodies and heads intertwined, dozing off for a nap, recharging for round two, or three, to come.
