My father Dave was working out hard on the rowing machine in our living room. Yesterday was my eighteenth birthday. I could hear him pumping away on the machine from the kitchen where I was preparing my morning protein shake. My cock started to harden in my shorts thinking about it, so I walked in to get a peek.
"Hey, dad," I said.
I wasn't expecting a verbal reply. He was breathing hard and just glanced at me and nodded before going back to concentrating on his workout. He was sweating, and I could smell the salty metal tang of it. I watched as his arm muscles bunched and he pulled hard on the rower arms, his powerful thighs flexed at the same time to push his body back. My dick got bigger and I walked back into the kitchen so he wouldn't notice me tucking my hard-on up into my waistband.
A few minutes later the rowing stopped, and my dad walked into the kitchen to eat a banana.
"How's it going Steve?" he asked, sweat dripping down his legs.
"Good dad, how was the workout?" I replied.
"Great! It's got me all worked up," he joked and then winked.
"Jeez dad!" I fake protested, almost choking on my smoothie.
My dad finished his banana in two bites and threw away the peel.
"See you in a bit," he said, and he walked upstairs to shower.
My dick throbbed in my shorts again once he left and i took it out and started stroking it. What had my dad meant when he said "See you in a bit"? He never joked about sex stuff. Was he even joking about sex stuff? It was too subtle to know.
I decided I didn't care. I was so horny I wasn't thinking straight. I walked up the stairs and down the hall towards my parents room. My mom was out for the day with some of her friends. My dad was in the shower in their bedroom, and I could hear the water running.
I opened the door to the bathroom, and saw my dad's naked figure through the wavy shower door glass. He looked muscular, powerful, and sexy. My dick throbbed again and I almost came right there in my pants. Then I noticed his hand was on his cock and he was jerking himself off. It was too perfect.
