"Hey," she murmured around the swollen head of my shaft, wiggling her arse over me. "You're forgetting something."
Oh, right. It wasn't that I'd completely forgotten about Dawn's wet cunt spread inches from my face in the darkness-I could smell her and still taste her in my throat. The thought of putting my mouth there made my cock stiffen more than I thought possible. I was just…distracted.
Dawn "mmmm'd" around the shaft in her mouth when I began probing between her lips. It was dark and my perspective was skewed-things were shifted and upside down. I tried to find the right direction, her swollen folds of flesh like a slick, wet labyrinth I tried to trace with my tongue. Dawn spread her lips open and rubbed her clit, encouraging me to find it. I followed her fingers, locating the hard little button of flesh and flicking my tongue there.
She sighed and rolled her hips, whispering, "Faster,” against my cock head. I obliged, now that I'd found the right spot, working my tongue over and over it. I loved the way she tasted, the way she pushed down against me when she wanted it harder. It was difficult to concentrate on giving pleasure while receiving it, but if I forgot, Dawn reminded me with her hips, grinding them into my face. I would have happily licked her forever, but I wasn't going to last that long.
In fact, I was rather close. All her sucking and tugging, her body half-naked and writhing on me, the little sounds she was starting to make that I was beginning to associate with her being ready to come, that little "uh, uh, uh," were all pushing me toward the brink. I felt it swelling like some incredible tidal wave rushing toward shore.
"Come for me!" She stroked my cock against her cheek. "Come all over my face!" I gave a low grunt and did as she asked, pumping my hips into her hand, feeling her mouth over my cock trying to catch wave after wave of my cum with her waiting tongue.
The knock on my door nearly propelled Dawn off me when I jumped, but I grabbed her hips just in time. My heart leaped to my throat and my voice was hoarse, thank God, a little sleepy sounding in my dazed confusion when I called out, "Yes?"
"David?" It was my mother's voice, right outside the door. Oh, sodding hell! We were in trouble now. Dawn sank down flat onto me and I pulled the sheet up to my neck, all just in time, too, as my mother opened my door a crack.
"Yeah, Mum? What time is it?" I mumbled, my heart still hammering like a race horse in my chest. She didn't have the hall light on, and that was good, or she would have seen the shape lying on me under the sheet, I was sure. I could only see Mum’s outline and I assumed she could only see mine.
"Did you hear Dawn come in?"
"No." I tried to keep my voice from shaking.
"Sorry to wake you, sweetheart," she said. "It's just late, that's all."
She pulled the door closed and I heard her moving toward the loo. Dawn let out a sigh of relief, throwing the sheet off. Neither of us said a word, frozen in place until we heard the toilet flush and we listened to my mum pad back down the hall and close her bedroom door.
"You need to go to bed." My voice was really trembling. Even my hands were shaking. Holy fuck! The realization that my mother knocking on my door in the middle of the night could have turned out very differently just then hit me square in the chest. I could barely breathe.
"I will," Dawn whispered. "As soon as I come all over your face."
"God," I breathed, feeling her mouth back on my limp cock, feeling it responding to her tongue in spite of the fact I'd just come minutes before. "We really shouldn't…Oh, fuck, Dawn!"
"Lick me!" She positioned herself over my face again, spreading herself with her fingers. And I did-god help me, I did, my blood still pumping adrenaline-compelled ice through my veins from the interruption by my mum. I licked and sucked her cunt harder and faster than I ever had before, no more looking for the right spot or trying to figure out what to do. I just went after her like a nutter, lapping and sucking and swallowing the whole of her cunt.
Dawn was breathing hard, whispering, "fuck, uh, uh, uh, fuck, fuck!" as I ate her. She remembered my cock then and put it back into her mouth, sucking me with all the earnest lust I seemed to be feeling, taking me to the hilt and gagging silently on my cock as she did and then taking some more. There was just no stopping it, no stopping us-we were doomed, and it felt like being sentenced to an eternity of ecstatic hell.
I felt her coming, her whole body tightening and releasing with it, bucking so hard I had to hold her arse in my hands and plaster my mouth over her slit, staying glued to her as she writhed against me.
She rolled off me then, tumbling to the floor. I held my breath, sure the noise would bring my mum running down the hall, but it didn't.
"Jesus," Dawn whispered. "That was-"
I felt it, too. It felt like I was floating somewhere near the ceiling.
"Go to bed, Dawn," I whispered. "Before we really do get caught." She crawled toward the door, using the handle to steady herself as she stood.
"Goodnight, David." She still sounded as dazed as I felt.
"'Night."
She opened the door as quietly as she could. "Hey…I’m not your sister, you know."
My head was too full of her, the blood beginning to return there. I didn't know what else to say. "I know."
I knew. Logically, I understood the fact-biologically, we weren’t related. But I couldn’t help how wrong it felt to be doing this thing. We’d grown up together. She’d lived in our house for over a year, treating me like an older sister would treat a pesky younger brother. And now, all of a sudden-this. How had we gotten here?
When she shut the door, I turned over in bed and pulled the pillow over my head to drown it all out. I ached all over, like I'd drunk a poison that was turning my insides to acid, but my throbbing cock was stiffening again, even now, at the thought of her. This was insane.
I rolled over and stared at the dull light of the moon on the ceiling. Everything had a silver sheen to it, like quicksilver, slippery and shifting. I closed my eyes, deciding to try to get some sleep. Maybe when I opened them again in the light of day, things would look clearer. It was all I could hope for.
Chapter Four
I spent the morning on the telephone ringing potential employers while Dawn moaned and groaned from the sofa that I was being too sodding loud. My mum had ripped her a new one at the breakfast table, after dragging her down in the first place. They even pulled out threats of sending her back to America, which had made her sober up. At least a little. When my parents left for work, she crawled to the living room, probably because she couldn't make it all the way back upstairs, and between bouts of snoring, saw fit to berate me for even existing on the same planet.
I wasn't having much luck anyway, although I did manage to schedule one interview later in the week, so I took a break and got myself a glass of milk and a couple of custard cremes. Hearing Dawn groaning again, I dug to the back of the fridge and found an Irn-Bru-a bright orange fizzy drink. She was lying on her back on the sofa with an arm thrown over her eyes. Her shiny, pink robe had pulled apart a little, exposing her thigh and a little bit of pubic hair.
"Hey." I squatted down and tried to avoid looking between her legs, remembering last night. It wasn't easy. "I brought you some Irn-Bru. Great for hangovers."
She groaned but peeked out from under her arm at me. "Ta."
Blinking and squinting, she sat up, reaching for the drink. I opened it for her and handed it over, watching how her robe split apart even further, showing me the curve of her breasts, the roundness of her belly and thighs. I watched her swallowing, the way her throat moved, and couldn't seem to find my breath. She handed the empty bottle back to me.
