My name is Kyle. I just turned 19. I have always been on the skinny side. I am 6'1 and you can see some muscle, but it is mainly due to me having very little body fat. I always look at my hairless thin body in the mirror and imagine what it would be like to have a body like my father's.
My father is 6'3 and solid muscle. He used to compete in body building competitions and now he works as a personal trainer. He spends hours in the garage that was made into a gym, lifting and getting even more ripped. He is always tan and has thick chest hair that runs in a line down his sculpted abs. He usually walks around in just a small tight pair of shorts that show off his sexy legs and massive bulge. I can't help but to admire his body and inhale as much of his manly scent as possible. Especially when he finishes his workouts and his muscles are shining with sweat.
One day, I decided to ask my father to train me, and he agreed to let me join him for his workouts.
Later that day my father said it was time to begin. He said we would start with a short run. Running with him would not have been bad, except I kept tripping over my own feet because I was more focused on watching his massive pecs bounce, and seeing his huge bulge bouncing along with them every step of the way.
It was a very hot and humid day, so by the time we got back, we were both dripping sweat. My white tank top was totally soaked, and all of my fathers chest hair was soaked as well. He put his hands behind his head to catch his breath, and I marveled at his hair pits completely soaked with sweat. I caught a faint whiff of the amazing manly smell coming from my father's pits, and felt my 7.5" cock start to stir in my shorts. Not wanting him to notice, I asked what we were doing next.
He told me we would start lifting, and with that I followed him into the garage gym. He told me he was going to walk me through exercises for every part of my body so that I could design a plan for myself.
It started with squats. He put the bar on his broad shoulders and squatted down. I marveled at his muscular back and perfect ass as he demonstrated. He put the bar back and when he turned around, I saw his massive cock hanging out the bottom of his small running shorts. He didn't seem to notice or care that his manhood was hanging out and told me to give the exercise a try.
I walked up and grabbed the bar the way he did, and proceeded to try the movement. When I was back up, my dad said my form was off and he would help me. He came up behind me and I could feel the sweat from his chest soak into the back of my tank top as his package pressed against my ass and he made me squat with his body. I could feel myself getting hard as he made me squat with him 5 more times.
I repacked the bar and asked what we were doing next, hoping he wouldn't notice the from of my sorts starting to tent.
He said next we would do Romanian dead lifts. He demonstrated by grabbing the bar and telling me to drive my hips back. As he showed me what to do, I saw his shorts riding up into the crack of his massive bubble butt. When he finished the set and stood up, his shorts had basically ridden up to a thong exposing his whole ass along with his dick and balls hanging out the front. I couldn't help but stare.
Then it was my turn to do it. After 1 rep, my dad told me to stop. He told me my shorts were to baggy for him to tell if I was doing it right, and told me to take off my sorts so he could make sure I was activating the right muscles. I protested saying that I wasn't wearing underwear. That was when my dad told me that he usually works out naked because its better that way. As he told me that, he bend down dropping his shorts and standing back up completely naked. I was awestruck by just how big my father's dick was. I was marveling at his physique when he asked what I was waiting for, so I removed my tank top and then hesitantly dropped my shorts to the floor praying my dick would stay under control.
