I have just had my first bi experience. I've thought about this for a long time and for some reason I was torn between a much younger guy and an older man. I am 42 so right in the middle. I have also discovered recently that i am a bit sub after my wife was in a strop with me one day, and started ordering me around in the bedroom. This carried on in bed and we both enjoyed her being in charge as I was made to carry out her instructions to pleasure her. I advertised on here to meet a local man and waited to see who would be first, the younger or older man. i was contacted by a guy of 68 who wanted me to suck him off. He liked the idea of me being sub and gave me instructions about what he wanted. He would turn up at my house and I had to answer the door naked. He would then order me to strip him and I had to kiss my way down to his cock. I was very unsure about that as I was not really intending that I would be kissing him. The day arrived and I waited for the knock on the door. My cock was rock hard and dripping when there was a knock on the door. My heart was pounding as my shaking hands undid the door. He was a bit taller than me and looked very well dressed and he spoke with a very nice accent and he entered and led me to the lounge. I stated to undress him and he made me kiss him on his body as I worked my way down. I finally removed his pants and his cock was brushing against my face. he told me to grab hold of it and I hesitated. He grabbed my wrist and made me wank him for about five minutes. His cock was larger than mine and also dripping wet on the end. I pulled his foreskin backwards and forwards and he then told me to suck him. I was turned on by this time but a bit hesitant to start sucking. He grabbed hold of my head with one hand and his cock with the other. He literally forced it into my mouth and then held my head very tightly with two hands. He started thrusting his cock into my mouth and I could not resist as he fucked my mouth. His cock was very thick and only just fitted into my mouth and a couple of times I gagged as it went in too far. Despite this I was so turned on as he began to breathe heavily. His cock seemed to swell as his hands tightly gripped my head and he let out a loud groan as I felt his hot cum squirt into my mouth. He must have been saving it for a long time as there was loads and loads. It dribbled out of the side of my mouth but the majority I had to swallow as he came again and again. I think looking back that he must have shot about 8 times and as he was cumming he was saying 'oh that's lovely' over and over. I had been saving myself for over a week and for the first time in about twenty years I came spontaneously without even touching my cock. It went all over his legs and feet but I don't think he really noticed. When he had finished I had to gently suck his cock as he got smaller and then lick it gently as well as his balls. He pushed me away and got dressed and I had to stay where I was until he just left my house. I was totally humiliated and felt absolutely fantastic but the best feeling though was that I had given somebody else pleasure.
