"Dawn…" I reached out to touch her hair, tucking it behind her ear.
"Don't say no." She shook her head and smiled, moving her mouth back over me now, covering me and taking me in. I groaned, moving my hips with her. I couldn't help it.
"Oh, hell," I moaned. "We’re not supposed to…This is so wrong!" Her mouth was heaven, slick, hot heaven up and down on me, her fingernails grazing my balls now.
She came up for air, still stroking me. "That's why it feels so good," she whispered, her eyes on mine. She was right and I knew it. Aside from the physical sensation, which was unbelievable, it was also the fact that Dawn was like my sister, and that we were both round the twist to even be thinking about this, let alone actually doing it on my parents' sofa.
She went back to work on me, and I could feel my pent-up lust for her ready to explode. I reached my hand down, tentative at first, feeling her breast through her bikini top. She smiled around my cock, still working it in and out of her mouth, and she didn't miss a beat as she reached around and undid her top, exposing her flesh to me. Oh my god, she was incredible.
I rolled her nipples in my fingers as she sucked me and that made her move up and down faster, moaning around my cock, sending vibrations down my shaft. Her tits swayed as she moved, brushing up against my thighs. I put my hand on the top of her head, pressing her down a little until she gagged. I groaned and she smiled again around my shaft, still not letting up. I wasn't going to last much longer and I think she knew it.
That's when she stopped, using her tongue to roll around tip, slipping under my foreskin to reach the sensitive flesh underneath, making me buck and groan against her. She stood then, slipping her bikini bottoms down and untying her bikini top, letting them both drop to the floor. Then she spread her pussy lips open, moving between my legs so I could see her.
"Do you want to touch me?" She put one foot up on my thigh so her lips were slightly open. I nodded, reaching my hand out and brushing it over the soft skin of her vulva, stroking in the direction of her trimmed bush, all the hairs seeming to direct my fingers between her lips. I spread her with one hand, using my thumb and forefinger, peering into the pink. The closest I'd come to a cunt was a brief feel down Sara Bailey's knickers in a dark bedroom at some party, just enough to feel hair and wetness before she pushed me away.
Dawn was wide open to me, in full daylight, and I took my time exploring her, running my fingers through the soft folds of flesh, parting them, watching them glisten. She moaned when my fingers brushed her clit and I stopped there, pulling the hood back so I could see it, just a tiny little thing. It amazed me that something so small could give her such pleasure, but it was clear it did from the way she rocked her hips and her nostrils flared and her head went back when I rubbed it.
"I want you to lick it." Dawn ran a hand through my hair. I looked up at her, surprised. She smiled and nudged me aside, lying down on the sofa and putting one foot up on the back and dangling the other towards the floor. I knelt down and stretched out between her legs, breathing in the smell of her. I hesitated-I didn't know what to do.
"Here." She looked down, opening herself with her fingers and pointing to her clit, stroking it with her fingernail as I watched. "Right here. Put your tongue-"
I didn't need a second invitation. I edged her fingers out of the way, rubbing my tongue over the little button, back and forth. She tasted tangy, strong, and I could smell her sweat from lying out in the sun all morning.
She gasped, rolling her hips a little as my tongue mashed against her, lapping and licking and swallowing the taste of her. It stayed in my throat, thick and rich. I watched her belly quiver, her breasts heaving, her breath coming faster as I moved my face between her thighs, my tongue exploring the sweet ridges and folds.
"Put your fingers in me." She bucked her hips. I slipped a finger down, between her slit, searching for that dark little entrance I'd seen yesterday.
Dawn squealed, her eyes flying open. "Higher." She reached her hand down and found mine, leading my fingers upward. I flushed, realizing I must have been pressing against her anus. She moved against me and I felt the soft, smooth walls inside of her. She started to rock, encouraging me to move my fingers in and out.
"Lick." She pointed to her clit. I did, my tongue moving over her flesh. She moaned, still moving her hips, and I pressed my fingers in her, trying to catch a rhythm between my lapping tongue and my plunging fingers. It felt a little like trying to walk and chew gum at the same time at first, but I got the hang of it. I knew for sure that I did when she hissed and grabbed at my hair, smashing my face between her legs.
"Oh, god," she moaned, and I felt the muscles in her fanny tightening. I licked faster, looking up and seeing her pinching and pulling on her nipples. My cock was dripping pre-cum now, throbbing against the sofa, and I knew there would probably be a stain there, but I didn't care. She tasted so good, and the way she moved and sounded and felt was almost enough to make me come myself.
"Oh fuck, David!" she cried, breathless, shaking. "Oooooo make me come!"
I grunted, moving my whole head as I licked her, plunging my fingers deep. She strained against me, rolling back and forth, making those same little noises she had yesterday, that little, "uh, uh, uh" until she stiffened and shuddered under me. I felt the muscles inside fluttering against my fingers when she came, her cunt wetter than ever now.
She reached for me as I sat up, grabbing onto my shirt and pulling me on top of her. My cock was pressed against her cunt, all wet and slippery, and I groaned. She kissed me, plunging her tongue deep into my mouth, exploring the insides of my cheeks, licking my teeth, her hands running up under my shirt and squeezing my nipples, making me jump.
"Dammit, Dawn," I murmured against her mouth, feeling her hand working my cock between her legs, aiming me. I moaned. "Ohhh fuck, no, we can't do this."
"We are doing this," she insisted. "I want to feel you inside me."
"Noooo," I groaned, sitting up and leaning back on the sofa, my eyes closed, panting. "Dawn, I can't. I just can't. You're…you’re like my sister!"
She crawled across the sofa towards me on her hands and knees, her tits swaying prettily, licking her lips, pretending like she hadn’t heard my protest. "God, I love the taste of my cunt, don't you?"
I wiped my mouth with my hand, still wet with her juices. I could taste her, smell her, and my cock was a throbbing, weeping pulse between my legs, standing straight up and defying my better judgment. She stretched out next to me, reaching her hand out to stroke me. It was a lazy, easy motion, but I was beyond any edge I had ever known-I was that close.
“Dawn, we’re not allowed…you know we’re not…”
"Did you like licking my cunt?" She tilted her head up to look at me. Again, she just ignored my protest like I’d never said a word. It was driving me crackers, forcing me to try to choose between my lust and my conviction. I couldn't forget for a moment that I was supposed to treat this girl like she was my sister-but she was on me now all the time and wouldn't let me even pretend we were related. And I was beginning to realise that it didn't matter, because lust was winning-it was kicking conviction's arse.
"Fuck, Dawn." I watched her hand on my shaft. Her arse was rising up, her feet swinging behind her. She was beautiful and I wanted her. God help me, but I wanted her. "You still taste so good in my mouth. I could lick your cunt forever."
"I might take you up on that." She grinned. "But first, I think you have an itch you need scratched." She grazed her fingernails over the head of my cock, tickling the frenulum. I groaned. She moved in, pressing her breasts against my thigh and taking my cock fully into her mouth.
