Dean had been going out with my older sister Helen for about two years when I found out hed screwed a girl he worked with called Gina. I knew I could use this to my advantage. Dean also worked for my Dad and so if he got caught out, hed not only lose his girlfriend but hed have to look for another job too. I was eighteen and devious. I had a huge crush on Dean from the first time Helen had brought him home. He was 22 and had a broad hairless chest and big muscled shoulders. His face was masculine and he was quick with a smile. I loved hanging out with him, and always tried to see him without his shirt on. He came away with us one summer up to the beach house and I loved seeing him in his togs. He was my wank fantasy. I found out he screwed Gina because I overheard a telephone conversation between him and Gina. Id picked up our home phone and Dean was using the one in the bedroom. Helen had gone to the shops and Dean thought he was home by himself. I heard them talking about how nobody could find out that theyd fucked, and Gina was crying saying she really liked him, but she promised him that she wouldnt say anything. I listened to the whole thing, and wondered how Id use the information. So, one Saturday when I knew that Helen was working, I went over to Deans house. He lived in a small flat on the other side of town. He was surprised to see me, but invited me in and even gave me a beer. We were sitting on the couch and I could tell he wondered what I was doing there. Dean, Ive got a deal for you, I told him. He sat back on the couch with an arrogant smirk on his face. Fuck, he was sexy. I was so hoping that my plan would work. Whats that, my friend? he asked casually. He had no idea what I was about to suggest. Well, I need to firstly tell you that I know that you fucked Gina Sanderson last month. I paused there to let that sink in. He looked pale and stared at me. Shit, he said quietly under his breath. How did you find out? Does Helen know? No, Helen doesnt know. I overheard you talking to Gina last month at our house. And I havent told anyone. I could tell that Deans mind was spinning. He didnt know what to do. Are you going to tell her? he asked me. God, this was great. He was completely at my mercy. That depends, I said. I wanted his agony to last. On what? I want you to fuck me, I told him. He looked at me with disbelief. What? he said, incredulous. I want to suck your cock, and then I want you to fuck my arse. I was getting more and more confident. You must be out of your fucking mind! he said. Im not a faggot. And Im not going to fuck your arse. I didnt even know you were into blokes. Jesus Christ Matthew, what are you thinking? He was raving. I just let him rant. It didnt worry me. I felt pretty sure hed agree to my conditions. He was in love with Helen and probably wanted to marry her. But I didnt care about that. I wanted his cock up my tight arse hole. If you dont do it, then Ill tell Helen what I heard on the phone. Shell dump you, you know. I said, smugly. You fucking shit! He sat back down heavily on the couch. Dean. I only want you to do this once. And I promise Ill never ask again, and I will never say anything to Helen about Gina. He didnt say anything, but lay back on the couch with his hands over his face. He was thinking. I sat across from him, staring at the bulge in his pants. God, he was cute. Just once, right? he asked. My heart leapt. Holy shit! He was considering it. Yep, just once. I want to suck your cock, and then I want you to fuck me. He looked at me for a long time. Youre a fucking arsehole, Matthew. I thought you were a decent bloke, but today youve shown me what a little cunt you really are. Yeah, Ill do it. But I will never respect you again, you shit. I didnt care. All I heard were the words Ill do it. My cock nearly burst out of my pants. He was still sitting on the couch, so I told him to stand up and take his pants off. He did. His heavy cock flopped over his balls and he just stood there wearing just a t-shirt. Shit. I couldnt believe I was about to get my mouth around that. I knelt on the floor in front of him. He stood proudly, not looking down at me. I didnt want to rush it. I knew I was being an arsehole, but I meant what I said to him. I only wanted it once and I would keep my promise about not saying anything. So because it was going to be a one-off, I wanted to make it the best I possibly could. I held his heavy cock in the palm of my hand. It was fat and wrinkled. I lifted it up so I could see his balls. They were hairy and hung really low. I loved that his cock wasnt hard. That way I could fit the whole thing in my mouth and feel it grow. I licked his balls. I felt him clench his arse. I knew he wasnt happy, but I didnt care. I had dreamed about sucking his dick for years. I nuzzled my face into his groin and licked the join between his torso and his legs. My face was up against his nut-sack and I pushed his limp cock up onto my cheek. I felt it growing a bit. Because he wasnt hard yet I could fit the whole thing in my mouth easily. It squashed up against the back of my throat. I sucked it like a teat, and used my tongue to massage the underside of his shaft. That worked. I could feel it get bigger and swell. I knew that when it was hard I wouldnt be able to fit it all in my mouth. I had to let some of it out, but I kept sucking and covering it with saliva. He just got bigger and bigger. I took the whole thing out and kept pumping the shaft. It was dripping with my spit and I played with the end of it with my finger. This whole time Dean was just standing still. He didnt say a word and he didnt touch me. His hands were by his sides and he wasnt giving me any encouragement at all. Well, even if youre not liking it, your cock sure is, I said, hoping hed loosen up. Get fucked you shit, he said. The hate in his voice kind of scared me, but I was in too deep to stop. The damage was already done, so I might as well enjoy this part of it. My own cock was throbbing hard in my pants, so I took a second to take my jeans and undies off. It felt heaps better now that my cock was free. I knew I couldnt wank myself because I would cum quickly.
