When I was home from school when I was 21, I got caught by my dad while playing with myself in his room. I was home for the weekend and got in a bit earlier than expected. I was quite horny. I had been jerking off and edging for the entire 4 hour ride ride home. When I arrived, I realized I was there a good few hours before my dad got off work. Being as horny as I was, and as attracted to my dad as I was, I decided to finish myself off while huffing a pair of his used work briefs. My dad is 6 foot and 3 inches. He is about 300 pounds of muscle bear. Quite hairy. From sneak peaks I've got in the past, I know his dick is big. Atleast 9 inches and quite girthy. He works on a construction site and comes home all sweaty and covered in dust and mud. Anyways, I went into his room and found a pair of his briefs. I dropped my pants and underwear, and jumped onto his bed. I pressed rhe briefs to my face and took a deep inhale of them. The smell of his sweaty balls, taint, and ass filled my body and made me VERY HARD. I continued to press them to my face e and breath in their amazing aroma. While doing that, I started to stroke my hard cock. I was having the time of my life. I was so enthralled by his aroma that I didnt notice he had arrived home early. I was deep huffing his briefs with my other hand gripping and stroking my shift when he walked into the room. I still hadn't noticed him while he stood there watching me. I opened my eyes to find him standing there in the doorway. I panicked. I immediately used his briefs to try and hid my dick with no success. I was freaking out and trying to come up with some excuse to explain why I was jerking off in his bed with his underwear wrapped around my face. While I was freaking out and stammering, he just stood there smiling. He said "Son, it's ok. Don't freak out." I tried to calm down but could not. I was also still raging hard. I was able to catch my composure for a moment to realize he was rubbing the front of his pants. To my surprise, he was rock hard. He said to me "Listen here son. It's perfectly normal for a son to have a sexual interest in their father. Let me help you explore that side." He walked into the room and pulled off his shirt. Some sweat fell down and landed on me. I still had his briefs covering my cock. He then undid his belt and snapped it off. Slowly, he took off his pants to reveal his massive cock, throbbing in his drenched briefs. He then reached down and pulled the briefs off of me. He said "Now son. These are old and arnt the best." He then instructed me to get up and down onto the floor on my knees. Like a good son, I obeyed. He placed his dirty hand on the back of my head and shoved my face into his crotch. My nose landed just to the side of his balls and just slightly down. He commanded me to inhale. I took the deepest hit of his scent that I could muster. It was amazing. His crotch was wet with sweat and smelled of rhe most masculine musk I have smelled in my life. He then pulled me back by my hair and with his other hand, pulled his cock out from behind his briefs. He then slapped my face with his cock and rubbed his balls on me. He then had me open my mouth and suck his dick. My god did he taste amazing. All of this had made my cock so hard I was starting to leak some cum without even touching my cock. He face fucked me for a good few minutes. He then instructed me to get onto the bed. He got onto his knees and started to suck me off. I was trying so hard not to cum but I wasn't able to resist. I shot my load into his mouth. My 1 week load that I had been edging for about 5 hours. I had about 7 pumps of cum in my dad's mouth. He pulled back and looked mad. I apologized that I had not warned him. He just grabbed me and forced me to my knees. He then jerked off into my mouth. While pumping his load in me, he instructed me, with his mouth full of my cum, to not swallow yet. He then helped me to my feet and he pulled me in close. We then made out with our loads and swapped cum. We made out like this for about 3 or so minutes when he forced me back to my knees. He then spit what load he had in his mouth into mine. He then forced my mouth closed and commanded me to swallow. I did just as I was told. The feeling of mouth of our massive loads going down my throat made me hard all over again. He then picked up the pair of underwear he had on, wiped rhe cum off of his face and cock, and handed it to me. "Here son. Use this and pleasure yourself to the thought of what we did here. Atleast until we can do it again." He then went into the bathroom. I sat there on the floor, covered in sweat and cum, hard and ready for more.
