Shortly after I asked my wife to marry me, her father asked me to join him on Saturdays to work out at his health club. At the time we belonged to the same chain of clubs but worked out at separate locations. I was happy to accept his invitation, I saw it as a good opportunity to bond with my future father-in-law.

At the time, my workout was typically a cardio workout, either running on the track or swimming laps, followed by resistance workout on the weight machines. My father-in-law’s routine was to play tennis with his best friend, and then finish with light weights.

We typically meet up in the weight room as we finish our workouts. Afterwards, we hit the showers, jacuzzi, and sauna in the men's locker room. Now back in the day, every man in this locker room was naked, and did not think twice about it. None of the overly modest behavior you have seen in locker rooms today was present back then.

Our after-workout routine was to go to our lockers and get undressed. Take a shower together, soak in the Jacuzzi tub, and then hit the sauna. We would repeat this sequence several times before taking our final shower and heading out for lunch together. The entire time we chatted about the events of the day, how work was going, and about the upcoming wedding.

That first day I worked out with him as we sat in the sauna chatting, I noticed him checking me out. We were both sitting on the top benches, but on opposite sides of the sauna from each other. He had an unobstructed view of my large flaccid cock and low hanging balls as they hung over the edge of the bench.

Now many guys may object to this statement, but all guys check each other out. I have been experiencing guys discreetly checking me out to outright staring since I was in middle school. I did not think much of my father-in-law checking me out.

Over the next few weeks, I noticed each time we were naked together in the locker room I would see him looking at my junk. Sometimes he was more discreet than others. To be honest I checked him out as well from time to time. Compared to most of the guys in the locker room and sauna my father-in-law had a nice thick flaccid cock, nowhere as long as mine, but thicker.

After working out with each other for about 6 weeks he finally said something unexpected. We were in the sauna in our usual top bench spots opposite each other. We were reading sections of the Saturday morning Tribune. When unexpectedly, after the last guy left the sauna, leaving the two of us alone, he said, "Damn you are hung!" I chuckled nervously and agreed with him. He then asked me if I got any bigger than that. I said I did. After an awkward moment he went on to say, "Be careful with that thing, don't be hurting my daughter with that big bat."

He never said anything else about it after that. We continued working out together for a couple of years until we moved out of town. Though he was silent he continued to check out my big cock every time we were naked together.
