My wife refuses to give me a blowjob even though she did before we got married. Just after Covid curiosity got the better of me so I thought I needed to try sucking a cock to see why she did and no longer does. Through a friend of a friend I met a guy in his early 60s and after a few messages I arranged to meet at his place on my way home from work late one afternoon. When I arrived we chatted whilst straight porn was playing on the TV then when I felt comfortable or rather stopped looking so nervous we went to the bedroom where he had a four poster bed and yet more porn playing on another TV. This time rather than single male female action this video was a girl getting spit roasted. As I looked at the TV he handed me some stockings and told me to strip and put them on and lay on the bed and wait for him to return. I did this and after a couple of minutes he came in naked with a fat soft circumcised cock and shaved all round. He tied my hands to the bed then asked me to lift my legs a bit and tied them too before placing a metal chastity cage on me and locking it in place. Finally he blindfolded me. He then asking if I was ready straddled me and pushed his cock in my mouth. I started sucking feeling it grow hard in my mouth, it was definitely fat and 7.5 inches long so he said. I believe him as it was not much bigger than my slim 7 inch circumcised cock. As I sucked him he told me what a dirty boy I was and how if this was my first time I could become expert very quickly. As he spoke he started to half ride my mouth as I sucked more and more then without warning he shot his hot cum down my throat in three blasts. He then climbed off and untied me and removed the chastity cage and blindfold then went off to make a cup of tea leaving me naked on his bed horny and wanting to cum. I enjoyed sucking him off so asked if I could suck him again whilst I wanked which he agreed too making me kneel in front of him and suck until I cam on a towel on the floor. After I had cum I took the stockings off and sat naked in his lounge as we had tea and he told me about a friend he had that had an even bigger cock to fill my mouth but that meet has never happened.
