I grabbed her hips and stopped her. “Dawn, don’t,” I said. “Please. It’s bad enough that I can’t resist you. Don’t tell me that you’re under age. I’m supposed to protect you, and I never even thought to ask your age. I’m the worst fucking uncle ever.”
Dawn leaned down and hugged me. “I’m sorry Johnny, I’m so sorry. I was just teasing you. I love you, Baby. You do protect me. You’re the best fucking uncle ever.” She started to giggle, and started moving again, riding my hard cock. “Best fucking,” she said, giggling again.
“They go by dates,” Mary Beth said as she sat our champagne down on the coffee table. “Doesn’t matter what time she was born. Today, she’s 18.” She sat down on the loveseat and sipped her champagne and watched Dawn ride my cock.
Dawn leaned down and whispered in my ear, “That’s true, they go by dates, but… 9:30 PM,” she said. “Just so you know. I may be legal, but you’re fucking a 17 year old. How does it feel?”
I looked at her and put my hand on her face and caressed her cheek. “Fucking incredible,” I said. “Worth the jail time.” An errant tear ran down my face as I said, “I love you, Dawn.”
She stopped moving on me. She moved her hand to my face and wiped the tear away and then pressed her lips to mine.
“Oh God, Johnny, I love you so much. You’ve always been there for me and I’ve wanted you for so long. I never thought I would have you. This is so wonderful. Thank you. Thank you for my birthday present, Baby.”
“You’re welcome, Sweetie,” I said. “I’ve always loved you, and given the beautiful and sexy woman you’ve become I’ve had improper thoughts about you for some time now. So this is a pretty sweet present for me, too.” I sucked a nipple into my mouth. She gasped, then moaned as Mary Beth appeared next to us and sucked Dawn’s other nipple into her mouth. I glanced sideways at her. She had shucked her clothes and was gloriously naked, just like us. Her body was beautiful.
“Oh my God,” Dawn said. She looked down at the two of us, watching us suck her breasts, and started riding me harder.
Mary Beth licked her way down Dawn’s flat little tummy and began tonguing her clit. Dawn groaned and grabbed Mary Beth’s head. Mary Beth put her hand on my abs for support. Because Dawn was moving on me, Mary Beth’s tongue alternated between licking Dawn and licking my cock. It was the most erotic thing I’d ever felt.
Dawn stopped moving then slowly lifted off me. Mary Beth followed, lapping at her cunt and simultaneously licking away at my cock. Dawn pulled all the way off me and rolled onto the couch next to me, watching. Mary Beth’s tongue was still all over my cock. She stopped and looked at us, seeming to suddenly realize what she was doing. Dawn giggled. Mary Beth grinned sheepishly.
“Hey,” she said, “I’ve always wanted to see what it’s like. Dawn, you were right, you know, you don’t have to worry about me. I love Johnny but I’m not going to steal him away from you. I just want to see what he tastes like. I’ve just always wanted to try this on a guy.” And with that she sucked my cock into her mouth. Dawn and I both groaned, and Dawn leaned into me and kissed me hard.
“Your lesbian girlfriend really is your girlfriend now, Johnny,” she said. “And I don’t mind sharing.”
Mary Beth may be a lesbian but she was sucking my cock like she’d done it all her life. Her tongue had a dexterity and strength that would make a porn star jealous. She sucked me hard while her tongue worked magic on the sensitive underside of my cock. She cupped my balls and bobbed up and down with furious intent. I knew she would make me cum soon and I wanted that, to cum hard in her mouth, to turn our friendship into something forever much closer, but I also wanted something else even more. I grabbed Mary Beth’s head and stopped her and pulled her up and slid down the sofa until I could kiss her, a passionate tongue-battling kiss. She pulled away, breathing heavily.
“Why did you stop me, Johnny?” she said. “I want to make you cum. I want to see what it tastes like.”
I groaned at the thought of that, but said, “I want that too, Babe, but first things first, you have to finish what you started,” and pushed Mary Beth’s head down into Dawn’s crotch. Being a good lesbian girlfriend, Mary Beth went right for Dawn’s clit.
Dawn’s eyes opened wide and she looked at me and started to say something but then she lay back down on the couch and moaned and her hands buried themselves in Mary Beth’s hair and pulled her head into her pussy. All the while, her eyes were open wide and locked on mine.
“But…” Dawn said. “But…”
“I know you’re not gay,” Mary Beth said as she slipped a finger into Dawn’s wet pussy. “But I am, and I was just sucking your uncle’s cock and loving it. All bets are off, so just settle back and enjoy the ride. We’re all just friends and lovers today. Besides, I’m really good at this.” She licked the length of Dawn’s slit and moved to suck her clit and Dawn groaned and thrashed on the couch and wrapped her arms around Mary Beth’s head.
Mary Beth’s ass was on display in front of me, high in the air as she knelt on the couch driving Dawn into the first of a series of orgasms. I’m not gay either, I thought, and a guy can only take so much. I thought about asking permission first but I didn’t, hoping our friendship and the heat of the moment would make it okay. I grabbed Mary Beth’s hips and waited a moment to see if she would resist, and when I saw that she was simply continuing her good work on Dawn I guided the head of my cock to her opening and drove myself fully into her.
Mary Beth lifted off Dawn and screamed and I stopped moving, buried deeply in her, afraid that my judgment was horribly wrong. But then her head whipped around and she looked at me with a wild-eyed expression and said, “Yes, Johnny!” and I cupped her breasts and began to slam into her.
Dawn’s eyes were wide open, watching me fuck Mary Beth. I suddenly realized that in this convoluted new game of friendship and love and incest, I might be hurting someone I dearly loved. I stopped moving again and said, “Dawn?”
