A couple of months ago I switched jobs, and as a result started working weekends and having two or three days off during the week. In some ways this worked out to my advantage, and one of those was that I was able to go to the gym during the weekdays and practically have the weight room to myself.
There was one guy who must have had a similar schedule to mine since it seemed like we were always working out at the same time. Being the only regulars at that time, and quite often being the only ones there at all, we naturally gravitated towards each other. At first we just talked about working out, but before long we began to banter with each other, and that's when things started to get interesting.
I always called him by his first name, Frank, but he almost always called me "Son," and usually in a mocking or patronizing tone. I guess I didn't think much of it, even though at 22 I probably could have been his son. He seemed to be somewhere in his mid 40s, judging by his balding head and the gray flecks that dusted his thick black body hair, which covered almost every part of his body I was able to see, even the tops of his fingers and up to the base of his neck where he began shaving.
Once while I was doing bench presses Frank stepped up to my shoulders, towering above me and giving me a great view of the large package he was carrying in his gym shorts. Caught at this magnificent sight, I paused in the middle of a rep, and before I could finish he slipped his hands under the bar and helped guide it to the catch. "Looks like you need a spotter, Son. I wouldn't want you to hurt yourself." He said.
I was a little upset that my set ended prematurely, and along with it that fantastic view, so I struck back with sarcasm. "Gee, thanks Dad. What would I do without you to watch out for me?"
Since I had never called him "Dad" before, I was surprised when he immediately responded, "Well Son, that's what fathers are for."
After that, all the banter between us was exchanged with his calling me "Son," and my calling him "Dad." He really got into it, and to be honest, I really got off on the idea of having such a hot dad. I began to wonder what it would be like to explore the expansive body of this "father figure," but was discouraged by the casual comments he would drop about sex with his wife, or how appealing some of the other women at the gym were. Still, this gave me an opportunity to pretend that, as his son, my virginal sensibility wasn't ready for such talk, and I protested that I still had to jerk myself off until I was old enough to experience "real" sex. He would laugh at this and assure me that "Your father still pulls his own pud quite frequently."
One afternoon I was able to time it so we finished our workout at the same time. In the past he would always head into the locker room while I was in the middle of a set or something, and I didn't want it to blatantly look like I was following him in to see him change, although I desperately wanted to do so. Before we were even in the locker room, I felt myself getting hard in anticipation. I diverted my thoughts, but that only worked until I started seeing him strip off layers of workout gear.
He slipped off his tee shirt first, and although he was about an inch shorter than my 5'11", with his stocky frame his chest seemed twice as big around as mine. It was completely covered in hair, as I suspected, except for the two quarter sized nipples. Next, he removed his shoes and socks and then slipped off his gym shorts, leaving him naked except for his packed jock. His back had little hair on it, but his ass had almost as much as his chest, and was just as solid. Finally, he stepped out of his jock strap and I was pleasantly shocked when I finally set eyes upon his cock. He packed a huge basket in his shorts, but it wasn't because of the length; flaccid, he had about five inches but it was thicker than any dick I had ever seen. It was uncut and hung even with two large furry balls that were just as thick as his broad meat.
I instantly got hard, and luckily hadn't removed my gym shorts yet. My mind raced for a way to leave my shorts on since I didn't think he would respond well to my hard-on. One last furtive glance at his ample cock and balls and then I said, "You know, Dad, I think I'm gonna hit the sauna before I call it a day."
"Hey, that's not a bad idea, Son. I'm not in any hurry," and he pulled his shorts back on and shut his locker.
I followed behind him on the way to the sauna so I could rearrange my hard-on in my shorts and make sure it wasn't too noticeable. Once inside, the dim lighting and thick air added to my concealment so I could oogle away and not worry about the consequences. We were the only ones in the sauna, and my aroused condition prompted me to direct the conversation in a similar direction.
"So Dad, why did you decide to have your own son cut when you enjoy such healthy cock hood yourself?"
This received a husky chuckle. "Yeah, I noticed you checkin' out your old man."
The sultry air hid my blush. "Well... it's just that I've never seen one... I mean, an uncut one before."
"It's okay, I guess it's natural to be curious about what your dad's carrying around."
I took this comment as a green flag. "Is it true that the foreskin is more sensitive than the rest?"
"Yeah, that's one of the upsides. But you also have to clean it more often or you can have problems." He said.
"Have you ever let it go too long and had `problems?'"
"No, believe me, soapin' up down there isn't a chore."
I knew a lot of the answers to the questions I was asking, but kept on asking them just to keep talking about his cock. Finally, after inquiring how he needs to manipulate the foreskin in order to clean under it he cut me off.
"You know, Son," he said, "You're making much too big a deal about a little bit of extra skin. I tell ya, it doesn't make all that much difference. Although, if you're so curious I could just give you a closer look at it so you'd know these things for yourself."
My heart skipped a beat. "Yeah, I'm sure it'd be educational, but you might give some old lady a heart attack when she walks in on your anatomy lesson."
"Well, I was sort of thinking the showers might be a little more appropriate, Son."
He took the words right out of my mouth. We headed back to the locker room and grabbed a couple of towels. The showers were set up as stalls down a long passage and we walked to the two at the end. He stepped out of his shorts and hung them up on a hook outside the stall, then he gave me an expectant look when I hesitated.
"Don't worry about throwing a rod, Son, it's natural at your age when you're talking about handling your dick so much." He turned on one of the showers and closed the curtain and then nudged me into the other. It clearly wasn't built for two people, which gave me a chance to really take in his overpowering man odor that had accumulated from both working out and sweating it up in the sauna. With mere inches between us he reached down and grabbed his cock. "See, your dad's not built much different than you are," he slid the skin back and forth a few times, "just a little extra slack on his tool case."
"Still," I said, "I wish I could have mine back. I'd love to know what it feels like just once." I let my voice trail off, feigning ignorance, and just stood there hoping he would bite.
He didn't even say anything, he just reached down and grabbed my hard cock with his left hand and guided it to the fleshy tube in his right hand. He then pulled back his skin and when our cockheads were pressed against each other he slid the casing back over both of them, covering my swollen dickhead and nearly half of my seven inches. It was incredibly warm and soft inside. My dripping precome caused my cock to slip around the top of his cock inside of his skin.
"You like being tucked-up inside your dad?" He asked under his breath. I nodded an affirmative. He began to slowly stroke both of our cocks at once. "It feels great to slide it back and forth over the head, doesn't it?" I just moaned unintelligibly. "This is what your daddy feels every time he pulls off a load." I could feel his cock start to swell inside of his foreskin, but he still kept me inside as it got tighter. I put my hands on his massive chest for support as I gave way to the sensation. "It looks like your dad's gonna have to finish the job now that he started, huh?" I moaned again as his grip became more firm and his strokes quicker. "Sometimes your dad plays with his balls while he does this to really get him off." With his other hand he cupped both his balls and mine in his huge meaty paw and began to lightly jostle them together. I looked down and saw his cock had grown a couple more inches in length and was now even thicker than before. As the strokes became faster and harder I lost more and more control until I was nearly hanging off of his chest.
"Dad... it's... I'm going to...come."
"Yes... fill your dad up with your cream. Come on."
His strokes became furious. I wanted it to last but couldn't hold back, and began to shoot load after load into his foreskin. He kept stroking, and while I was coming he dropped his hand away from our balls, slipped it around my waist, and pressed me hard against him. Before I was through shooting he gave a rough groan and I felt his come flood over my own and spill out onto the floor. I nearly collapsed as my body shuddered, and he held me up with his one arm behind my back. We just stood there pressed against each other until we regained our senses. I looked up into his face, stricken with contentment.
"Wow, Dad, I guess I really needed that."
"You know I'm always happy to help out my son."
