becoming a bi cuckold hubby

I am a bisexual, married white man in my 50s, and the following story occurred when I was in my 30s, and had my first, life-changing cock sucking experience.  I was married to a lovely woman and had a decent sex life at home, with the only problem being that I have a smaller-than-average sized cock and I have always been self conscious about that.  I normally could not bring my wife to orgasm from just fucking her with my small dick, and usually finished her off orally after I had cum in her.  I enjoyed reading porn on the internet, and my favorite stories were those about cuckold husbands who enjoyed eating creampies from their wives’ pussies, after being fucked bare back by a hung stud.  I knew that my wife would never allow another man to fuck her, but I at least had those fantasies to enjoy, and I often thought about that when I was sucking my own cum from her pussy, imagining that a big cock had just fucked her.
This story happened when I was a salesman for a sporting goods company, and I was out of town at a sporting goods convention for a week.  I was at the convention with my sales manager, Larry Masters, who was 40 years old at the time, and another salesman, named Marcus Brown, who was about my age and was a black man.  We arrived at the convention center on the weekend before the show started, and spent two long days setting up our exhibition booth, to be ready for the show opening on Monday morning.  Our assignment for the rest of the week was to work the booth and make sales to the convention attendees.  Our plan was to go out and get a quick dinner after the show closed each day, and then go to one of our rooms to drink and play cards for the rest of the evening.
We didn’t have time to play cards on Saturday or Sunday nights, due to the long hours setting up the booth, but on Monday night we met in Larry’s room for some relaxation.  After we played cards for several hours, and were by this time getting pretty silly from drinking so much, Larry suggested that we play a game of truth or dare.  I know that sounds a little odd for grown men to play this type of game, but given our drunken state, it seemed like a good idea at the time.  The early rounds of the game were pretty bland, with each of us asking the others to be truthful about various topics, mostly related to our company and the office we worked in.  As we continued drinking, the topics eventually became sexually oriented, and we were asking each other to be truthful about how we felt about some of the hot women in the office, and whether we’d like to fuck them, or had actually fucked any of them.  As it turned out, Larry said that despite being married and getting plenty of pussy at home, he had a high sex drive and a big cock, and had fucked several of the women in the office.  He was a pretty sincere guy, so I tended to believe him.
