Wanting To Jack Another Guy

This happened about 15 years ago. My wife was gone to work and I invited a male friend to spend the night with me. We stayed up talking until late that night. I asked him if he had ever taken a steambath before. He said he had not, so I told him to strip and come into the bathroom. We went into the bathroom and I turned on the hot water. We were both naked and I was semi-hard. He sat on the commode lid and I sat on the bathtub edge. I was leaking precum, but kept it hidden from him. We were just talking about different things, especially about how to check yourself for testicular cancer. He said he had never been shown or knew how. I proceeded to explain to him how it was done and that with the hot water going was a perfect time. I reached over and took his ball into my finger tips and rolled it around. This was the first time I had ever touched another guy's dick or balls. I so much wanted to grab hold of his young cock and stroke it but resisted the urge. He began to talk about how he couldn't keep his dick hard when he was jacking off. We talked a little while about different things, but never did go any further. I wish to this day while I had my hand so close to his dick that I would have just stroked it until the cum squirted out.
