Jess first came to stay with me when she turned eighteen. She was my half-sister, and she needed the time in London to look for work. Of course, I said I'd let her stay at my place while she did. Me and Jess had never been exactly close; we'd played together a bit when we were little kids, but since then I'd only ever seen her at weddings and family events. Waiting for her at the train station I didn't really know what to expect. In fact, I wondered if I'd even recognize her after four or five years apart.

I needn't have worried. I spotted her the moment she stepped off the train. In some ways she was still the same as before: shoulder length brown hair tied up behind her head; intelligent blue-grey eyes; a small and slightly upturned nose in the middle of a rounded, lightly freckled face. In other ways however, she hand changed. To start with, she'd grown breasts. Not huge, but they were there, and noticeable. She was wearing the top few buttons of her shirt undone, which sort of lead my eye down towards them. The same shirt stopped just short of her middle, revealing a inch or so of bare flesh before the hem of her jeans began.

"Jess!" I called. She caught sight of me and made her way over.

"Hi." She grinned and we shook hands. "Hi Nick." I could smell perfume on her; a scent that reminded me vaguely of apples.

I wasn't really used to having a girl around in the flat, but I figured that we knew each other already and so she wouldn't mind the mess. I had done my best to tidy up, but the place was still out of order. Jess, however, didn't seem to notice.

"So you, like, moved here out of school?" She gazed around, and then went over and slumped down on the sofa.

"Pretty much."

"Cool." And just like that, she'd moved in. It didn't take more than a day for her stuff to appear in the bathroom. I guess because we'd known each other for most of our lives, it didn't feel so weird.

During the day I would go off to work, and Jess would head out to her interviews or whatever it was she did. By the time I returned she'd usually be back in front of the TV, or reading in the kitchen. Often, she'd have stripped down to just a t-shirt and panties. She didn't make an issue of it, and I decided not to either. After all, I figured it was a sign of trust.

One night, as I was finishing up on some design work on the computer, she wandered in and hovered behind my seat.

"I'm bored, Nick," she said. "Just bored, you know?"

"Any luck with the job hunting?"

"Not much. You mind if I watch you work?"

"Go ahead."

She pulled up a stool and sat down right behind me, her naked legs on either side, her arms crossed on the back of my chair. She rested her chin on her arms and I felt her breath tickle the side of my neck.

"So what are you doing?"

I shrugged. My throat had suddenly gone dry. "Just some drawing work."

"Oh?"

I told her a bit about my job, just chattering aimlessly. All the while I was very aware of her legs, exposed and spread. The position was oddly sexual, all the more so because of her semi-nakedness. I found myself thinking back to a moment earlier that day when she had been lying on the sofa. I hadn't been looking, exactly, but her panties had been exposed then. Red silk, tight over the smooth bump of her crotch.

It was weird. She was my half-sister after all, but at that moment I struggled to think of her as anything other than a girl. A woman. Her heavy body so close to mine, her breath on my back.

I finished talking about work, and in the same instant realized that I was hard. Shit! Would she notice? I shifted a little to hide it, but even as I did she removed her arms from the back of my chair and sort of grabbed me around my middle. Her chin rested on my shoulder. I froze, and the two of us stayed like that for a second before she got up, yawned, wished me goodnight and left the room.

I sat there for a long while, a little shocked, thinking over what had happened. She had touched me--quite innocently I was sure--and I had got hard. But she was my half-sister. Surely I shouldn't even be thinking about her in that way?

For that night, I dismissed it. Wrote it off as just a weird little moment. And for a few days that was fine. That is, until Sunday night.

It was evening and we were both sitting on the sofa watching TV. Once again, Jess was dressed only in a t-shirt and underwear. I had begun to relax again around her. After that one time I'd not had any sexual feelings towards her. Even the fact that I could see her bra through the white cloth of her t-shirt wasn't too distracting. All the same, I was making a concious effort not to stare.

We were both sitting around, kind of relaxed. I had one arm layed out along the back of the sofa, so that my hand was right behind her head. On an impulse, I started gently playing with her hair. It's a habit I have whenever I'm with a girl, and so I just started doing it without even thinking.

"That's nice," said Jess. I stopped at once, but she pouted. "No, come on. Please."

Well, I figured, it couldn't hurt. I went back to twisting her hair around my fingers, pulling a little. I found her ear and ran a thumb behind it, stroking at the little hairs at the back of her neck. She tilted her head back and gave a pleasurable little moan.

"Rub my neck?" she said. I ran my hand beneath her hair and gripped her neck. Thin beneath my fingers. I could feel the tendons near her shoulders. I squeezed, gently at first, then increasing the pressure. Her hair danced ticklishly over the back of my hand. "Harder," she said, pleadingly. I complied.

I listened to her breathe. Slow and deep. I realised that I was hard again, but this time I didn't really mind. I mean, what was so weird about this? She was a girl after all. What was wrong with getting a hard-on while touching a girl, even if she was my half-sister?

Jess bent forward on the sofa, hands crossed over her knees and chin on her wrists. She flipped her hair forward over her shoulder, exposing her back. I pushed my knuckles in between her shoulders blades and rubbed up and down. I could feel the bumps of her spine, and across them the strap of her bra. I shifted closer and pushed down a little harder. Jess moaned with pleasure. "That's good, Nick."

I kept on rubbing for a minute, enjoying myself, enjoying the feel of Jess' body. Then she sat up. She flipped her legs up onto the sofa and lay back against me, grabbing my arm as she did so.

"Nick," she said.

"What?" I shifted awkwardly. Her change of position had taken me by surprise, and I was keen for her not to feel how hard I was. For a moment she just held my hand in both of hers, and then she put it flat on her stomach.

"Go on," she said. And so I started rubbing her stomach, round and round in little circles, pressing hard. Her belly was so much softer than her back, so much more give to it. But still she wasn't satisfied. She grabbed my wrist, pushing my hand higher, higher. Up towards her breasts.

"Jess?" I said. "What are you doing?" Her eyes were shut and I could feel the in and out of every breath she took. I could feel the beat of her heart; it was racing.

"Just do this, please." Her voice itself was a moan. "Please Nick."

To be honest, I needed no further encouragement. I was painfully hard already, and the sight of Jess' bra through her t-shirt only made it worse.

I got off the sofa and knelt down beside it while Jess stretched flat out on her back. I pushed both hands up underneath her t-shirt, all the way up until I felt the soft round weight of her breasts. They sat flat ot her chest, cupped in the satiny material of her bra. I let my fingers graze the bottom of the cup, then creep up over and hold her. I squeezed.

Jess swore under her breath. Her back arched up a little as if she was trying to get me to grip her harder. I did. Her nipples were hard under my palms. Her t-shirt was pushed up, giving me a view of her flat pale stomach. Her own hands hovered around her groin, close to her heat. I set up a rhythm, massaging my hands over the soft mounds of her breasts. She moaned again. This soft girl, this light and wonderful girl. My half-sister.

My half-sister.

"Don't stop," Jess complained. But I let go of her and backed off from the sofa.

"This is weird," I said.

Jess was staring at me, the color high in her cheeks. "No it's not. You're a man. I'm a woman."

"We're related."

She stared at me, speechless. Then she shrugged. "So?" She swung round into a sitting position and with a single movement pulled her t-shirt off over her head. "You want me don't you? You're stiff. I felt it."

As if in response to her words I felt a powerful, urgent throb in my cock. She was right, I did want her, more than anything. But still . . .

Jess huffed in irritation. "Come on," she said. "Just hold me, at least. I'm going crazy here."

Those words decided it. Half-sister or not I couldn't resist her any longer. The closeness--the willingness of her beautiful body was too
much. I'd worry about the consequences later.

I sank down on the sofa, taking her with me. My hand was between her legs, and I was kissing her neck, my other hand over her shoulders pulling her into me. Her breasts pushed into my chest, her own hands looped my neck. The smell of her apple perfume, of her arousal. I hooked a leg over her hip and we ground into one another. My fingers slid over the dampened silk of her panties.

"Go on." She was murmuring encouragement, just incoherent little words and noises. I found the edge of her panties, hooked my fingers in, fumbling in my urgency. I pulled the flimsy material aside. beneath she was slick wet with her own juices. I rubbed her, fingers sliding, dipped into the slippery cup of her insides. She jerked as my fingers entered her, then exhaled. I gripped her tighter.

I could feel the pressure building. I was going to come, and soon. Each time I thrust my hips my cock rubbed up on her stomach and hips. We were seperated only by my jeans and then thin material of her panties. I moved the hand on her back down and gripped her ass. Smooth and round and giving.

I started to move my hand inside her, curling my fingers up against the walls of her body. Jacking her off even as she moaned and writhed in my arms. Her skin tasted of sweat and girl. I ground against her as I masturbated her. Bringing myself closer, bringing her closer. She was helpless, a shivering, whimpering creature.

Jess came first. She convulsed, once, twice. Through gritted teeth she was making these little rhythmic yelps. "Mm-mph, mmph, mmph, ah . . . oh . . . oh . . " Her pussy spasmed around my fingers and I curled them deep into her. Two more quick thrusts brought me to the edge and I came too. The molten, sparkling explosion. That desperate heat. My hand tightened on her ass, digging roughly into the flesh. She convulsed again, rigid then limp. I was taut against her, coming.

After what seemed like an age, my orgasm ended. Jess had already gone limp and soft in my arms. We lay together in a stunned and radiant haze, our breathing growing slowly calm. Jess was hot as blood against me. I withdrew my fingers from her and simply held her, neither of us moving or speaking for the longest time.
We slept separately that night, more or less out of habit. In the cool, rational aftermath it still seemed a little weird. I had all these memories of Jess being a little kid and the two of us playing tag at weddings and stuff. And now . . . it was as if some new part of her had opened up to me.

The next morning, Jess greeted me in the kitchen, again dressed in only a t-shirt and panties.

"Hi Nick." She sounded almost embarrassed, or shy. I wondered if she was rethinking the night before. Perhaps this could end up being awkward.

"Hey Jess. You all right?"

She grinned and nodded. She didn't seem inclined to talk about what had happened and so I didn't push it. I did, however, find myself looking at her in a different way. Now that I had held her breast, felt the fullness and the give of it, I could look at the way her t-shirt pressed against her chest and imagine it all over again. Or I could look to the place between her legs . . . the panties she wore today were blue and frilled.

"Nick?" Jess folded her legs; she had caught me looking. I was about to apologize, but then I saw that she was grinning. I grinned back. "You going to work, Nick?"

"Yeah. You?"

"Got an interview later. You, um, in a rush or anything?" She sounded casual, but her words brought me to a stop.

"Why?"

"Just wondering." Again, light, casual.

"I've got some time."

Jess stood up. "Good." She grabbed my hand and lead me out of the kitchen. "I've been thinking about last night."

"Yeah." I was beginning to harden again, but still unsure. Were we about to repeat what we'd done, or did she want to talk it out. Had I made a mistake?

"Yeah," said Jess, and I could hear the smirk in her voice. "And I've decided that I should pay you back."

My cock hardened considerably. "Pay me back?"

"Yeah." She had lead me through to the bedroom. She let go of my hand and went to draw the curtains. When she had, she turned around to face me, hands behind her back. She was blushing slightly. "Last night was the best . . . I've never . . . that was the best I've ever felt. It was wonderful."

"Thanks."

"Now it's your turn." I wondered if I should tell her that I had come as well last night. I'd sort of assumed that she knew, but it seemed that she didn't. I decided to keep it to myself.

"What did you have in mind?" I asked, raising an eyebrow.

Jess came right up to me and pushed me back against the wall. "This," she said simply. She sank down onto her knees, still peering up at me. Her hands reached for my belt. After a moment my cock, still hard, was free. She wrapped a hand around the base and, without any further words, took the head in her mouth.

"Jess . . ." I was surprised by her eagerness, how she hadn't even hesitated. As though she was experienced at this. It was weird; before that moment I'd never even have considered that Jess might be into giving blowjobs. Yet here she was.

I groaned as she began to tongue at me. Waves of pleasure seemed to emanate from the tip of my cock and rise up all through way through me to my brain. Her hands were on my thighs, gripping and releasing as she tilted her head around my cock.

I reached down and stroked her hair, touched her beautiful face. "That's good, Jess," I said. "That's good." As if in response Jess took my deeper. I felt her swallow, her tongue still swirling around me. She swallowed again, taking me deeper as she did, all the way down into her throat. The head of my cock was gripped impossibly tight. And again she swallowed, again she took me deeper.

This was unbelievable. This tiny, delicate girl, who I had known all my life--her hands and body smaller than mine, softer and more fragile than mine--she was on her knees in front of me, my throbbing cock halfway down her throat, her lips wrapped tight around my shaft. Insane.

And yet there was something curiously right about it. She was no stranger to me. She was my half-sister; a thing we'd shared since we'd been born. My own flesh and blood. Closer to me than any other girl ever could be.

Her mouth took me towards my climax. She was squeezing with the muscles of her throat and tonguing at me in rhythm. I was ready to come, but at the same time I wanted this sensation to continue for as long as possible. Jess was an expert.

I held back, but couldn't last forever. I felt the waves of pleasure rising, spiralling up and out of my control. "Jess . . ." I warned.

She made that swallowing motion again, and the pressure around the tip of my cock was relieved. She drew back, exposing the length of me, slicked with her saliva, twitching. The feel of her lips and the tip of her tongue slipping over the head of my cock was what pushed me over the edge.

"Come on my face," she said, her voice sounding breathy and urgent. "On my face." She tilted her head back a little and encircled my cock with one hand, pointing it towards her. As the first spurts rose up she shut her eyes. Then every muscle in my body dissolved and I was coming. Squirts of my semen hit her and stuck, spattering over her cheeks and her small nose. One wild spurt landed in her hair. A thick trickle ran down towards her mouth and she caught it with the red tip of her tongue.

When I was finally empty, Jess released me. She fell back onto her haunches, and I saw that one of her hands was buried in her crotch. Wet stained her panties. She had been masturbating even as she sucked me off. Now she put a finger to her face and wiped away my semen. She licked it off her finger, smiling, showing me her mouth.

"Jess," I said. "That . . . that was amazing."

She smiled.

"Like I said--I wanted to pay you back. Nick." Her cheeks glistened with the remnants of my come. That sharp, wicked tongue flicked across her lips. "Have fun at work."
After that, Jess had to leave for a couple of days. It wasn't her decision; a storage lock-up where she was storing some of her stuff flooded and she had to go sign off on some documents to get the insurance. So for the next few days it was just me, alone again. I'd gotten kind of used to having Jess around. Her sudden absence, especially given what had happened between us, was lonely.

It also gave me time to think. Far too much time. I spent ages wondering whether what we were doing was wrong. After all, she was my half-sister. We were blood-related, even if only by a fraction. These problems dissolved however, when I thought of her body: her full breasts, her slender arms, the fine curve of her backside. And I recalled her words when I had protested to her: "So? You want me don't you?"

Yes. I wanted her. In the end it was as simple as that. I only had to hope that in the intermission she hadn't changed her mind about how she felt.

After moping around for the better part of the week, I finally received a call from Jess late on Thursday. She'd be returning for the weekend to resume her job search.

"So I guess I'll see you then, okay?" Her voice light, casual.

"Okay. I'll meet you at that station."

Both of us talked as if everything was normal. Weirdly, what we'd done didn't feel like something that could be talked about on the phone.

Knowing that she was coming back filled me with a kind of energy; nervous and excited both at once. Waiting for her at the station, again I found myself not knowing for certain what to expect. Should I maintain the casual act? Should I touch her?

As it happened, I didn't need to worry. The first thing Jess did when she got off the train was to walk right up to me, slip her arms around my shoulders and kiss me on the lips. My mouth met hers and our bodies were close, electric. I put my hands on her back and drew her into me and we kissed like that for a long time.

Eventually she drew back. "Well," she said. "Nice to see you, Nick.

I grinned. Couldn't help it. "Likewise."

She was wearing a halter top, drawn inwards beneath her breasts, and a short, light skirt that showed off her legs. I found myself wondering if she had dressed that way for me. When she put those clothes on in the morning had she imagined that I might remove them for her later?

"Let's go home," she said, putting an arm around my waist. Then in a whisper, "I missed you."

Any doubts I'd had dissapeared in an instant. The drive home was torture, but we finally arrived. Jess hung over me and giggled into my ear as I fumbled with my keys. I was hard. She knew. We were like lovers. We were.

Jess grabbed my hand and lead me straight into the bedroom. We stood at the foot of the bed, hands held. Sophie was biting her lip, fighting back a shy kind of smile.

"Well?" she said.

"Well what?"

"Aren't you pleased to see me?" Teasing, subtle. For a moment the smile flitted on her face, but she controlled it.

"Of course I am." We were closer together now.

"Well then . . ." she whispered.

"Well." And we kissed again. My hands found the hem of her top and lifted it up over her head, interrupting her kiss, briefly pinioning her arms above her. Her hair was lifted up and then fell about her face. She was wearing the same satiny bra she had worn the last time we touched. I had forgotten just how beautiful she was. She seemed to glow, just standing there, no part of her not soft and curved and pink. The desire I felt for her just then was overwhelming, intensified all the more by the knowledge that what we were doing was forbidden.

"Here." She handed me something small and square--a condom. It was a moment before I realized what this meant.

"You want to . . ." I didn't know what word to use. But I didn't need to. Jess nodded, still smiling. "But . . ."

She silenced me with a finger to my lips. "I'm not a kid anymore, Nick. You know that." And with that she started undoing my shirt, removing it from my shoulders. When that was done her hands went to my belt. She stripped me naked and pushed me backwards onto the bed. Taking back the condom she bit open the pack, climbed up onto the bed and straddled me, one milk-white thigh on either side of my body. My cock stood erect, rock hard. She pulled out the condom and rolled it down over me. Her hands were cool and quick--she knew what she was doing.

Next, still straddling me, she reached up behind her back and undid her bra. I realized that though I had held and squeezed them I had not yet seen Jess' breasts. She seemed to know this too, taking her time revealing them, holding the bra loose in place for a minute before removing it altogether. She was naked now from the waist up; the only covering she had was her skirt.

Leaning forward she placed both hands in the middle of my chest, then lifted herself up and positioned herself right on top of me. Even before we touched I could feel the radiance of her heat, smell her desire. And she lowered herself onto my erect cock. A moment of resistance and then I slid inside, engulfed by her blood-hot wetness, the walls of her insides smooth and slippery as silk. Her head tilted back, eyes closed with pleasure. Her small hands kneaded ecstatically at my chest. I reached down and held her at the hips, steadying her, stroking the length of her thigh.

We stayed like that for a time, without movement, adjusting to each other. The knowledge of it hit me. I was inside her. I was penetrating Jess, my own dear, pretty half-sister. My own part-flesh, close as anyone. Closer now.

Jess started to move. She did this by pushing down against me with her hands and lifting up using her legs. I could feel the muscles in her thighs tense, feel the slick depth of her move around my cock. Then she would tilt her hips forward and sink down once more for another stroke. I'd not tried this position before. It was strange; for once I didn't have control, couldn't set the pace or the strength of the thrusts. The sensation was unbelievable.

Jess was making these little moans each time she moved. I'd noticed before how vocal she was, but as we continued she seemed to really let herself go. She flicked her hair back and increased the pace. The groans she gave seemed to come from somewhere deep inside her, somewhere beyond her control. Her wetness ran down onto my stomach, dripped onto the bed.

She had begun to shake; I could feel it through the hands on her thighs. Her face had taken on the same desperate, concentrated look that she'd worn the last time she came, and the noises that she made were becoming higher and more orgasmic. "Nick," she cried. "Nick . . . oh fuck . . . oh god . . . ahh . . ."

I felt it when she came, the burst of fluid between her legs, the shuddering of her muscles. The way she squeezed pushed me beyond endurance and I was coming too. Her voice was one, long high scream. Her body taught and trembling. My orgasm exploded out of me, and through it I heard her calling my name. My hands tightened on her thighs, and I pushed my hips up off the bed deep into her bucking, shuddering body. There, locked together, we came.

Jess remained on top of me for a while afterwards, regaining her breath. She was trembling still, but weakly now, as though exhausted. At last she lifted herself off and slumped down on to the bed beside me.

"That . . ." she began, but left the sentence unfinished. We kissed, long and lazy. Me and my half-sister. She pulled back. "This," she said, smiling, "is going to be an interesting few weeks."

 

very good , in fact excellent would be a better word .
