Becoming A Cock Sucker

Like a lot of guys on here, I had a friend in my teens that I hung out with. we would look at porn mags and jerk off. One time my buddy said he would suck me if I would return the favor. We ended up sucking each other but finished off by jacking. He moved away my sophomore year and I got interested in girls.
Several years and marriages later, I moved to a larger city and started flipping houses. My wife worked weekends and I had a lot of free time on my hands. One day while out getting some supplies, I stopped in at the local adult book shop just to check things out. I went into a booth and started watching a video of a wife getting gangbanged and decided to jerk myself off. I noticed a couple of fingers sticking through the hole in the wall so I put my dick in there.
The mouth on the other side felt wonderful. This guy really knew what he was doing. Feeling a hot load coming up in my balls I pulled back out. I looked through the hole and saw a nice sized black cock being stroked on the other side and immediately felt the urge to suck it. I motioned for him to stick it through and he did. I did my best to suck a load out of it, but he pulled out before he came. too. I jerked off my load and hurried out of the booth.
Later on when the wife got home from work, I thought about what I had done and fantasized about it while we fucked. I decided if I ever had the opportunity again, I would definitely swallow any hot load that was offered to me.
That would be a couple of years later and another story to tell.
