Bi Sex Melissa was a kinky girl. She always wore heels even though she was tall, I don't think she owned any flat shoes. She favored short skirts, preferably leather; if the weather was warm, her flat belly would be on display. If it was cold, she liked sweaters that covered but didn't hide her. She died her hair black, and kept it fairly short. She had rings in her ears and one in her nose, and was normally bedecked with bracelets and necklaces. I've lived with her for a few years. We were hanging out one evening, and I was playing with her breasts. Melissa had great breasts, lovely little handfuls of smooth flesh. Her hands roamed over my chest, pinching my nipples. "The problem with guys is they don't have tits." she observed. "Sure we do, they're just small." I answered her. "No;" she refuted, "These are just shadows, there's nothing in them. I'd like to feel up some real tits." "You can feel up your own, they're lovely." I suggested. "You can suck your own cock, too." she answered, "But it isn't the same, is it?" Melissa began to suck my cock, and we spoke no more about it that evening. "What about that girl over there?" she asked me the next day as he walked through the park. "What about her?" "Don't you think she has great tits?" "Well, they're big anyway." "I'd love to play with them." Melissa said. "Really?" "For sure. I wonder she'd let me?" "I tend to doubt it." "Maybe I should ask." "What would you say if a stranger walked up, and asked to play with your tits?" "If it was a guy, I'd kick him in the balls." "I rest my case." A couple of nights later, we were in a club. "That woman over there is flirting with me." Melissa claimed. "The blond?" "I bet she'd let me play with her tits." Melissa said. "I'm going to dance." Sure enough, the blond was soon dancing with her. She was a bit older than us, in her 30s. She had a well rounded figure, yet a certain attractiveness. Melissa went home with her. "It was wild." She told me the next day when she came home. "We made out on her couch, and played with each other's tits." "What else?" "I guess we fucked. Well, we kissed and everything for a while, and got naked. Then we went in her bedroom, and she licked my clit. I licked hers, too. It was fun. Then we put our pussies together and rubbed them." "Did you come?" "Twice." "I wish I was there." "In your dreams!" She laughed as I undressed her and dragged her into the bedroom. A couple of days later, we were dancing at a concert. Melissa turned from me, and danced with another woman. I grooved along a couple of yards away, watching. Damn, they were sexy! Melissa turned from the girl, and began to dance with a guy. She often flirted with other men, she loved the way it made me jealous, insecure, and horny. She grinned at the over his shoulder and put her arms around him, grabbing his leather clad ass. They moved together to the beat for a short time, and I saw her long leg pushed between his. Her eyes and gleamed at me and she laughed at my consternation. She ground her hips against his, held his head in her hands, and whispered into his ear. He nodded affirmatively and they released each other. Melissa began to dance with me again, her firm little breasts bouncing in her loose top, her ass swaying in her tight little skirt. She grinned at me, and put her mouth to my ear so I could hear her. "I promised that guy a blow job." she said, "His dick goes halfway to his knee." "You're not really going to do it are you?" I asked. This was a new escalation in our little power struggle. "No, you're going to." "What?" "Suck his dick. I want to see you suck his dick; I had such a good time with that woman last week, and I want to see you enjoy it the same way." "But I'm not bisexual, Melissa." "That's what I thought too, but you have to try it to be sure. Come on, he's waiting for us." Melissa broke away from me, and headed for the door. I saw the guy waiting for her there; wide shoulders and a smooth chest visible through a light shirt that wasn't buttoned. Blond spiky hair over a handsome young face wearing a broad smile. A tight muscular ass in black leather trousers. Melissa was equal to his height in her high-heeled boots; he put his arm around her slim waist, and they went outside together. I hurried after them. By the time I caught up to them, he had Melissa pinned against a car. Her hands were on his ass again and they were kissing. "This is Barry." Melissa said breathlessly. "Barry, this is my boyfriend Greg." "Hi." he said enthusiastically, holding out his hand. His other one stayed around my girlfriend's half dressed body. "We could go back to my place if you guys want too." he offered as he shook my hand. "Great!" Melissa agreed. He had an apartment not far away. My knees went rubbery as we all entered. There was no way I was going to suck dick; Melissa might have thought homosexuality was a joke, just another fun little thing to try. But I knew that there were two kinds of guys; cock suckers and normal. And I was normal, and I was going to stay normal. "Let's get naked!" my kinky girlfriend declared as soon as we were inside the guys place. "All right." he declared, and began to strip, facing Melissa who was doing the same. Even the shape of her body is kinky; thin and angular. I watched helplessly. I didn't want to join in, but that meant I was left watching as this guy, a complete stranger, wrapped his arms around my girlfriend. As usual, she'd been wearing high-heeled boots, and she'd left them on along with her stockings. They were fine black net with wide bands at the tops. There naked bodies embraced, his hands roamed across Melissa's skinny body and tight round ass, his cock was clamped between her thighs as they kissed, her jet black hair contrasting with his peroxide blond. She pulled away from him, keeping one arm around his shoulders as she took his stiff cock in her free hand. She pulled on it and looked at me. "Barry, I'd like you to meet Greg's penis!" She laughed gleefully, "Why don't you come on over here and touch it?" she turned to her new friend; "Greg has never touched another man's penis, at least that's what he says, can you believe that? Never!" "Actually, I haven't either." Barry admitted with a shrug. "Go on man, it's cool." They were both looking at me, my girlfriend's hand tugging on his erect dick. "Maybe he's too straight." Melissa said, "Maybe he can't handle it. Listen Greg, if you don't want to play with us, just go home. I'll be back tomorrow, or maybe Monday." She chuckled and wrapped her arms around Barry's thick neck again, sticking her tongue into his mouth, pushing their small firm breasts against his chest, wrapping one of her long legs around his back. She broke free of him again, and looked at me. She cooked a finger and beckoned me forward. I advanced, like a lamb to the slaughter. She pointed to his cock, which was stiff in her other hand. Tentatively, I reached my hand out and touched the shaft with my fingertips. My heart was pounding in my ears; it wasn't that big a deal I kept telling myself. "He's blushing!" Melissa said, "I've never seen Greg blush before. Wrap your hand around it Greg, give it a good squeeze!" I could feel my heart beat increasing as my hand wrapped around his hot stiff cock. My face was burning and my throat was dry, I couldn't understand what was so frightening, it was just a penis. It wasn't even as big as Melissa had said at the concert, it was only a little bigger than mine. It pulsed in my hand, throbbing with life. Melissa fell to her knees and pulled it against her face, her hand over mine. She grinned up at me. "Want to suck it?" she asked. "Hey baby, I thought you were going to do that." Barry said. "I want to see him do it." she said, standing up and lifting one foot high into the air, finally bringing it to rest on Barry's shoulder. His hand was around her waist for support, and his big cock in her hand touched her spread middle. "This is so wild." she said, and pushed the tip inside of her body. Barry grunted softly, and Melissa shuddered as the stranger's cock slid an inch inside. The position was nearly impossible, but he managed to give her a few strokes before it slipped out. Melissa put her foot back on the floor and took Barry's hand. She reached her free hand forward and took mine, then dragged us both over to the bed. "O. K. Greg, you have to do it now." She told me, "Come on, I want to see you suck dick!" "But I don't want to do it Melissa." I said. "Why, you're afraid you won't like it? Or afraid you will? Stop standing around like a fool and get in bed with us. You can lick my pussy first if you want, come on big boy, lick me!" I always enjoyed licking Melissa, because it made her come like crazy. And anything was better than sucking cock, so I got on the bed and put my face between her thighs. Her vagina was open and wet, another man's penis had been there just a minute before. I wrapped my arms around her long skinny thighs and put my tongue inside. I looked up at her to see that she was kissing Barry. Both I watched their lips and tongues toying with each other, their hands stroking and touching each other's naked bodies. Melissa's legs wrapped around me, which would have been nicer if she wasn't wearing the boots. She clamped me tight and arched her back as she came. I came up for air, to find Barry's cock in my face. The two of them were looking at me, Melissa's thighs still held me. Her hand was on my head, the other on his cock, pushing the two of us towards each other. "You know you want to." Melissa said, "We both know you want to, don't we Barry? Open wide Gregory!" It was all so sexy; the taste of her in my mouth, her succulent thighs around my shoulders, the way the two of them touched and kissed, the big throbbing cock at my face. Impulsively, I opened my mouth for it. It wasted no time, it moved between my lips. My face was burning, my ears were pounding, I didn't know what I felt. The cock, the hard pulsing living penis of a man was in my mouth, and it was good. No, that's not true; it was great, it was wonderful, fantastic. I'd never known a feeling so sexy, so raw and powerful. I wrapped my hands around his ass and sucked him, I held his shaft and balls and I sucked him, I filled my mouth, throat, and vision with it, and I sucked him. The shock of the pleasure I felt was nearly greater than the pleasure itself; how could something that had seemed so bad in my imagination feel so good in real life? My whole being knew nothing but that big hot organ, the taste of it, the smell, the sexy smooth hardness. My heart was thumping with excitement and my cock was swollen to bursting in my trousers as I held his soft hairy balls and pushed his penis against the back of my throat. "Oh yes, oh yes," Melissa chanted, "This is the greatest! I've never seen something so sexy in my life! Somebody had better fuck me." I was still dressed; I couldn't get undressed because my head was full of cock. I had to keep it there, just for another moment, it was too good to surrender. But he pulled it away from me, tearing it from my grasp. Like a heat guided missile, it shot straight into Melissa's throbbing wet pussy. She squealed with laughter and delight, thumping him in the ass with her boots as his cock rammed home. I fumbled with my clothes, belatedly peeling them away as our new friend fucked Melissa like a mad man. She was coming again as I got back into bed. Melissa curled her arms around my ass and hauled my stiff cock to her face. Her whole body was bouncing with the action of the other man, her lips were tight around my organ, I was about to come when she took me out of her mouth, and stuffed my dick into his. Then I was coming, coming into his mouth. He was sucking my dick and I was squirting at the same time, they were hands-on my ass and balls, I think Melissa was coming to, and Barry at the same time, his big dick jammed inside her. Depleted, I sat back on the mattress as Melissa pulled Barry's face down and sucked my come out of his mouth "You're a kinky lady." Barry said, "You're fucking damn right I am." She affirmed proudly. Melissa is terribly pleased with me. She says she's going to take me with her to her lover's house, the 30 year old blond. Things are suddenly looking much more complicated, and much more interesting!
