It was a nice warm summer night, and was at a friend's place sitting around the fire pit talking with friends. Beer was flowing and everyone was having a good time. When it got later, all had gone except the host, my friend and I. Then the host went to bed leaving the two of us. We were pretty loose, and talking about sex. Somehow, we got to talking about threesomes and bisexuality. I told him that I had experienced a threesome, and I was bi-curious. He said that he was bi-curious too, so I took the impulse and walked over to him and put my hand on his crotch, rubbing his cock and balls. At first he looked shocked, but made no movement to object or stop what I was doing. I suggested to him that he drop his pants, and after a second or two hesitation, he did just that. I knelt down in front of him and pulled down his boxers.
His cock was rapidly growing larger, a beautiful curving erection begging for contact with my mouth and tongue. I was immediately attracted to his cock, what I wanted to do to it, and what I wanted to see and taste come out of it. My mind was obsessed with pleasing him. As soon as I kissed and licked his tip, I heard him groan quietly, and saw his head fall back. It really turned me on to know how much pleasure I was giving him. Knowing the feeling he was experiencing, I knew exactly what he wanted. I licked his seam from bottom to top a few times, then licked his balls and sucked them into my mouth, running my tongue around them a few times. I felt his hands gently resting on my shoulders, and knew I was doing things that he liked.
