Give docking a good try.
I am 38 and work in construction with my nephew Kyle and his best bud Sims. Kyle is 18 and Sims is 22 and an ex-Marine.
One day when we, the three of us, were taking a leak together, Kyle asked me if I wanted Sims to show me something? I said sure. Sims then faced me with his cock outta his jeans and held my cock in his right hand with the heads of our cocks meeting. We are uncut and approx 7 inches by 7 each guy.
Sims then squeezed our cocks together and bedamned if I didn't spurt my cum on his cock. He took my cum and using it as lube, jacked off himself. That was the most powerfuil orgasm of my life even tho I didn't get completely hard!
Sims said this was called 'docking', putting cock heads together with one guy jacking off both guys. I was sold! Sims said he and his buddies in the Marines did this to each other all the time. Sims then faced Kyle and they docked each other. This whole experience took only about 10 min each docking session.
When Sims docks me I don't get completely hard when I blow my load. Many times when he does me I jack him off. My nephew Kyle and me dock each other all the time now even tho we three are married. Other times the three of us will put two open pickup doors near each other and stand in the middle of the open doors and dock or jack off each other after work. No one can see us. What a way to go! It sure cuts down the tension!
