Dad was always so free when we went out on the boat. He'd grab a beer, strip off his trunks and catch those sun rays . Even though he had a great tan line from this short super tight white trunks of his. His trunks hugged his ass and package to leave little to imagination on his muscular ass he had and the big package that was held in. But he would strip in front of me but always had his back to me. Then would turn around and depending on how excited he was, sometimes he just hung soft and plump. Loved looking at his manly body, I was still a teen snd haven't deleveloped into the man muscles I was hoping for. He said son might as well enjoy yourself and take your trunks off and enjoy the sub, catch some rays, jug back a few beers and let's talk about your life son. I kinda of scuttled my trunks off while I sat on the cushioned chair, even though there were no boaters out near us. I got up to grab a beer from the cooler near dad , and then he grabbed me and brought me in for a hug. A tight long hug. He said I love you son. And wrapped his arms around me even tighter. I felt like I could melt in his embrace. Yes Dad I know. Really son do you know how much and what I'd do for you. Yes Dad. He let loose of his hug, and I grabbed my beer, as I bent over he kinda slapped my ass softly. I jumped a bit as he laughed and said that some tight ass muscles you got son. I just smiles stood near the back as my cock starred to go from semi to full hard on. I'm thinking shit. I can never control this muscle enough. As I turned around to sit Dad was for sure to catch a look at his son full frontal nude. He said son your turning into such a fine young man. Look at yourself. Bet your getting laid alot now that graduation is done. I just said not really Dad. Kinda busy with work and stuff. He said bull shit stuff, you need to make sure you take care of them balls and empty them out everyday. I thought more like 3 times a day now. As he went to grab another beer he just looked me in the eyes and shock his head a bit. Then I saw him reach for his cock and squeeze it and pulled on his balls, he turned around and had a full hard on. Dam dad. That is a thick son of a bitch of a cock dad. He just smiled and stood there. Like teasing me to touch it or something. It went quiet for a bit long quiet. Uncomfortable quiet. He then said touch it if you want Son. It's ok to explore with your old man. We all have had times when we jerked with another man. Here's your chance. I took a huge guzzle of beer down, emptied the bottle. And got up to get another bottle of beer opened it up. Watch his eyes as he watch me grow. I was at full mast and went to reach for his cock. He just stood and let me play and stroke it as I wanted to. For how long I wanted to. He just moaned here and there as I just his thickness and weight of his cock in my palm. Then I would grab his balls softly and roll them around my hand. He looked at me and said son pull on them harder. Your old man loves them pulled hard. Wow ,, ok Dad. I'm pulling and he said might as well taste your Dad now. I known its what you want. He pushed my head down to get me down to his cock level and said open your mouth and enjoy dads cock. And he went to fucking my mouth. Didn't take long but 2 minutes or so and was beating his nut down my throat. I looked up and saw the pleasure I was giving my dad. He was in heaven with his son sucking him dry.
