At first, I wasn't quite sure how to tell Rob about my fantasy as it was something I had been curious about since secondary school when I had first started thinking about sex. Rob and I had experimented together with everything;in fact, all of my sexual experiences have been only with Rob, and Rob only with me. We had tried lots of things and, over the past few years, had watched quite a few X-rated tapes but in each of those mainstream tapes, my curiosity continued to be piqued. Although they almost all showed girl-girl action, they never showed boy-boy action and that was something I was dying to see. Just the thought of watching a man with a raging hard-on of his own sucking on another hard-on was enough to start my pussy quivering. I finally got up the courage to talk to Rob about it one evening by starting the conversation on what tape we should get next time.After a few minutes of various new tapes we knew I mentioned my observation to him. "You know, Rob," I said. "One thing about those films that really gets me?" "No, what?" "They all have scenes of two women getting it on together, but, even when there are two or more men with one women, the men never do anything together." Rob looked at me with a raised eyebrow. "You mean, like sucking each other off or something? "Exactly." I regarded him carefully for a moment before jumping in. "I think that would be about the most exciting thing I could imagine. To watch a man give head to another man." Rob smiled at me. "It doesn't sound like you're talking about a film here. It sounds to me like you want to actually see that." "Well, I guess." I was a little embarrassed I had been so transparent. "Yes, I would." "Am I to be one of these two men?" he asked. "Of course," I said. "You have to be one of them. That's what such a turn-on." "And who's the other cock attached to?" he asked. I shrugged. I honestly hadn't taken my fantasy this far. Rob just smiled back at me. "Okay," he said with a shrug. "I'm willing. You love me and I love you. I guess I can give a guy head if that would turn you on." I couldn't believe it. My Rob was willing to go down on another man's cock just to turn me on. I was alive with passion. We made love hard and often that night, but it was the next night that Rob really surprised me. He called me to let me know that he'd be a little late, and when he got home, he had Matthew with him. I was surprised. I knew from Rob's talks about the office that Matthew was openly bi. I had even met him on a couple of office nights out. I have to admit, I had once thought he was attractive and tonight, it would be my man getting him! We had drinks and dinner together and then Rob told Matthew what it was we had in mind. Matthew nodded like he had known that all along, and he must have or he probably wouldn't have been there. We moved to the bedroom and we all stood around a bit awkwardly for a few moments before Matthew suggested that he and Rob both undress me. The feeling of Matthew's fingers pressing against me as he unbuttoned my blouse sent goosebumps over my skin and shivers through my pussy. I tried to stand relaxed, but my hand accidently grazed his hip, so I made it cross over to his crotch. I cupped his penis and could feel it starting to grow heavy. As he finished unbuttoning my blouse (with Rob on his knees unzipping my jeans) he pulled it off my arms, causing me to break my hold on his cock. I put it right back and felt him jump. "How am I doing?" "Oh you're fine," I gushed. "Just fine!" He reached his arms around me and unsnapped my bra at the same moment Rob began to peel down my jeans. I was starting to stroke Matthew's erection more firmly now and was disappointed when he stepped back to view me in my nakedness after Rob pulled down my panties. "You're beautiful," Matthew said, his eyes brushing over every inch of my body. Just then, Rob's tongue darted out and made contact with my clit and I nearly jumped. "Wait a second," I cried. "We can't start that with you two guys still dressed!" Rob nodded and stood up. "She's right, Matthew," he said. "Let's take our clothes off and get started." My eyes were riveted on Matthew as he removed his shirt and then began on his pants. He unbuttoned and unzipped them in one fluid motion, and it was then I saw he hadn't been wearing underwear. His perfect rigid cock stretched straight out toward me, and I noticed that Matthew was another fantasy of mine that I hadn't realised. In watching porn flims with Rob I had noticed with real curiosity the way skin on uncircumcised cocks would ripple over the cock heads. Rob, the only cock I had ever seen in person, was cut. Matthew's cock was uncircumcised. His foreskin was just beginning to pull back to reveal the fleshly tip of his tool. While Rob pulled his pants and underwear down releasing his own hard cock, I reached out and continued my stroking on Matthew's, watching his foreskin pull further back to reveal the head while I cupped my other hand underneath his balls to massage them. I could feel Rob's cock brush along my leg as he stepped over next to me. His hand started at my shoulder and dipped down to cup my breast, then went down my arm until he reached the hand that was stroking Matthew's rigid tool. He hesitated a moment, his hand riding back and forth on the top of mine and then as I slowly pulled my hand out from underneath his, I watched as his fingers wrapped around Matthew's cock. He continued waking Matthew off while I continued rubbing Matthew's balls. My free hand clutched Rob's penis and we stood there for a moment, me wanking Rob and Rob Matthew. I felt Matthew's hand join mine on Rob's cock and I watched in fascination as these two men with hard, rigid cocks, began to wank each other off. I could see the pre-cum starting to come out of Matthew's cock and I think Rob saw it too because he suddenly dropped to his knees. took a deep breath, then leaned in and let his lips lightly touch the head of Matthew's cock. I sat on the edge of the bed and let my hands go to my pussy when I saw that. Rob didn't stop. His hand pulled back on Matthew's cock to reveal the head and Rob's tongue stretched out and licked the soft underside of it then suddenly, he sucked the whole head into his mouth. I think I had a small orgasm as I watched his checks deflate as he sucked in more and more of Matthew's cock. I get wet just thinking about it now! I had another small orgasm when I first saw the head of Matthew's cock outlined along Rob's cheek, poking against it from the inside. Rob pulled Matthew's cock out of his mouth for a moment and licked his lips of Matthew's pre-cum. "How is it?" I asked. "How are you doing?" Rob glanced up at me. "I'm good. This is great and I like this." "You like sucking Matthew's cock?" Rob smiled. "Yes, I do. How about you?" he asked, then leaned forward and took a long suck on Matthew's cock. "Do you like watching me suck his cock?" "Yes," I said dreamily, my hands still on my clit. Rob looked up at Matthew. "How about you, Matthew? How am I doing?" "Wonderful," he breathed. "In fact," he added when Rob sucked his cock back into his mouth. "Much more of that and I'm going to lose control." Rob smiled up at me, and I had another orgasm, seeing him create a smile with his lips locked onto Matthew's penis.
