I never knew I had it in me

First of all I love everything about women, so I am a straight man but something happened a few years back that has troubled me ever since. My brother in law had fallen from a ladder and hurt his right arm. He said he couldnt shave himself and asked me to go to his flat and shave him. It was strange shaving somebody, I had never done it before. After doing it I asked if I could do anything else.

He stood right in front of me and said "there is one thing" and asked me to touch his jeans. I hesitated for a moment and then touched him. He then asked me to take it out. Having never done anything like that before it wasnt easy but I unzipped his jeans and put my hand inside then I felt his hard dick through his underpants and decided I couldnt go further. I told him I was sorry and left a few minutes later. About a month went by and my wife and I were visiting him at his flat one evening when he had a minor fit. We got him down the hall to his bedroom and I took his jeans and shirt off. He fell asleep so I covered him up and we left.

About a couple of hours later I told my wife I was going to check on him. He didnt live far and as I had a key to his flat I let myself in. As I walked through the door he was comming out of his bedroom. He stood there wearing just his underpants and my eyes were fixed on his bulge. I told him the bulge was pretty big and he invited me to inspect it. I stepped forward nervously and felt the bulge and his dick was rock hard. After about a minute I put my hand inside and took it out. It was huge, far bigger than my own. I started to wank him and he suggested we went to his bedroom. He laid down on his bed absolutely naked and I sat beside him.

As I wanked him he started to moan and wriggle and said he wouldnt be long cumming. Then he told mr to do it faster and I felt his dick jerking so I got ready with the tissue. His cum exploded from his dick and then it oozed out all over my fingers. He then laid there with his eyes closed and began to relax. I then took my own dick out and started wank. When he realied what I was doing he watched me. I knew I was on the brink of cumming so I put my dick on top of his and came all over the end. As I did so his dick started to jerk and he came on mine, and he finished himself off. So much for the tissue there was spunk everywhere.

We enjoyed doing similar things for a few months after that. One thing I enjoyed was watching him wank on the toilet while he pretended he was on his own. I did the same for him and it was very horny. Then he left to work 150 miles away so I see very little of him. It could never happen with anyone else and why I did it with him puzzles me to this day. When we do occasionally meet we go for a drink and I wank him off in my car afterwards.

Its all very strange because I dont fancy men at all and I only ever have fantasies about women. He is most definately bi and was like that as a teenager.
