“Hold on, I’d like a word with you two,” Mom told us as we went to get up from the breakfast table. I immediately felt guilty. I couldn’t think of a specific reason why and looked at Tim. He looked just as guilty as me but shrugged his shoulders as if to say, ‘I dunno’. We turned back to Mom who looked faintly amused by our exchange.

“Don’t worry, it’s nothing bad,” she reassured us and I let out the breath I’d unconsciously been holding in.

“As you are no doubt quite aware summer break starts in two weeks--” She had to pause for a brief chorus of yeahing. “Now I’m thinking that you’re old enough now that I won’t have to take time off work to keep an eye on you.”

For reasons that I wasn’t sure of at the time a little buzz of excitement went through me. I tried to keep it from my face. “Sure Mom,” I said calmly and Tim nodded.

“Tell me that I can trust you to behave yourselves and I’m not going to regret this,” she said looking at each of us closely. “Alexandra?” You knew it was serious when she used our full names.

“Absolutely,” I assured her.

“Timothy?”

“No problem,” he answered.

“OK,” she said, still eyeing us warily. “Don’t make me regret this.”

It wasn’t much later that I put a finger on (pun intended!) what it was that had excited me about them leaving us alone. At eighteen I was not a virgin. My first time was about a year earlier at a party, and it won’t surprise you to hear that it was also the first time I tried alcohol. He was cute and very gentle as he felt me up, and I was horny and bored of wondering what it was like. It was nice enough: a knee trembler against the wall with my skirt up around my waist and my panties down around one ankle. I didn’t cum, but I liked it well enough to know that, with the right guy and in the right circumstances, I’d very much like to put that right.

I’d dated a few guys since but, for one reason or another, hadn’t done the deed again. I was a normal horny teenage girl though and I’d been masturbating for years. I loved it but ... there was a constant sense of frustration at the restraints I had to impose on myself: huddled under the covers in case someone came in, having to stifle the cries and moans that I desperately wanted to make, and having to keep the volume turned down on the porn I watched.

Those first few days of the holidays were lovely. Mom insisted that we got up at the same time as them so we could all breakfast together but, after that, the days were our own. I didn’t do all that much, just thoroughly enjoyed not being at school. It was Thursday that I was really looking forward to. Thursday was when Tim did his radio-controlled car racing: I’d have three lovely hours all to myself!

I was already trembling a little as I got everything ready: a box of tissues to clean up afterward and a little bottle of lube just in case. It was a very rare luxury to be able to get completely naked and sit in front of the big screen on my desk with my feet up on the chair and my legs spread wide. Even though I’m not gay I’m really into girl/girl porn and the first video I pulled up was one of my favorites: two amateur straight girls persuaded to try some lesbian action during a calendar photoshoot.

The other joy of having the house to myself was being able to have the sound turned up so that I could hear what they were saying properly.

You can never be quite sure with porn but either it was genuine or the girls were incredibly good actors. Rachel’s expressions while Victoria licks her pussy for the first time are so beautiful and stunningly erotic.

Anyway, I was already a little moist just from anticipation, and, as the girls were kissing, I was rubbing gently over my clit hood and up and down my lips, feeling the wetness building inside me but denying myself actual penetration until they began sixty-nining.

I slipped an arm around my leg and slipped two fingers inside, sighing audibly as the need to be filled that I’d been feeling was suddenly getting satisfied. I tweaked my aching nipples and stroked my breasts, adoring the way I could give full reign to pleasuring my body.

I was very close to cumming but I needed something a little more ... hetero, so I opened a video of girls cumming while being fucked hard. I had two fingers of one hand flashing in and out of my pussy and my other hand rubbing my clit, getting closer and closer in sympathy with the girl on screen as she was plowed brutally from behind. As she got close I added a third finger, loving the way it stretched me to the point of just a little pain. She began to cum and I threw my head back and closed my eyes as I teetered on the edge, my back arched right up and my legs spread wide. Loud high-pitched squeals and gasps were coming from my throat as I desperately tried to achieve what I knew would be a spectacular release. Then something made me open my eyes.

There, standing to my left and looking directly at my groin, was Tim. He was staring right at my cunt. I’d never even been so swollen and wet and inflamed, and here was my little brother staring right at me! A massive thrill went through me and, with a mixture of horror and joy, I began to cum!

I tied to cover my pussy but my hands just stimulated me even more. Nobody had ever seen me like this, at my most vulnerable and exposed, but his expression was one of pure love and ... awe I think. It drove me to another level of arousal and I opened my legs wide and pulled my fingers out so that he could see everything, and kept stroking my clit until I began to cum again.

The first massive convulsion pushed my hips even wider and higher and a little squirt of fluid escaped. I couldn’t take my eyes off Tim’s face which had an expression of wonderment combined somehow with both innocence and lust.

Time seemed to slow to a crawl and it was a few seconds before my lust befuddled brain persuaded my fingers to stop their magical work. I screamed a little and cupped my sex with one hand while using my other arm to cover my breasts.

“Please Tim, don’t look,” I begged, trying desperately to stop it, but it was like trying to stop an avalanche. The hand covering my pussy was pressing on my clit and my other arm was brushing my aching nipples, and I shuddered violently again. The way his wide, entranced eyes were drinking in my wanton nakedness was pushing all my buttons and then I glanced down and saw the bulge in his shorts! Instantly another wave forced a grunt from between my lips and made my whole body quake again.

I didn’t know if it was several orgasms or one huge one but, with him watching me, I wasn’t sure they’d ever stop.

“Please Tim, please leave.” I implored him, but it was like he was deaf, and he showed no sign of having heard me. Still, I continued to shudder as my orgasm defied my silent pleas and just went on and on. And all the time my little brother continued to watch me cum.

Finally, he seemed to regain his senses. He looked up at my face. “Sorry, I thought you might like this,” he said softly and put a bottle of soda on my desk before turning and leaving.

As soon as he closed the door all I felt was a huge sense of loss: something in me had absolutely loved having him see me like that, and I had a sudden mad urge to call him back. Just the thought of it made my vagina clench hard. Then I remembered the bulge and, before I could stop myself, I imagined what it would feel like inside me. Instantly my pussy was alive and hungry again. Jesus fuck! I thought as I realized that I had a massive crush on my little brother!

I didn’t dare go near him for the rest of the day and over dinner and then breakfast we were both so quiet that Mom commented on it. We were equally mono-syllabic in our excuses and in the end Mom just sighed and tried to talk to Dad instead.

She had one last try before she went off to work. “So, what are you two going to be up to today?”

“I’m going over to Mona’s,” I replied: a spur-of-the-moment decision.

“All day?” she pressed.

“Yeah, probably,” I answered, looking down at my plate.

“And you?”

“Games ... online,” Tim replied, somewhat grudgingly.

“OK, see you later,” she said, getting up and kissing us both on top of the head. As soon as she’d gone Timmy ran off up to his room. I considered following him but just at the thought of it, my body started to respond.

I did go around to my friend Mona’s place but it didn’t really work: my mind kept going back to Timmy, and Mona asked me several times if I was OK. In the end, I made my excuses and left.

As I walked home I convinced myself that I had to talk to him: ‘We did nothing wrong but it can’t happen again’ sort of thing. My body disagreed completely but that was the way it had to be.

I went to his room but it was empty so I carried on to mine and found Tim asleep on my bed. It looked like he’d dropped off while hugging my pillow to his chest with the T-shirt that I slept in wrapped around it and pressed against his face.

I thought it was just about the cutest thing I’d ever seen. He’d clearly wanted to feel close to me, to smell my scent, and to imagine holding me like that. I actually felt a pain in my heart I was so overcome with emotion.

Without even thinking I put my arm on his shoulder, wanting to wake him so that I could kiss him. I felt him tense and then start to shake. For a moment I thought he was laughing and then, at the first rasping breath, I realized he was crying.

He obviously thought I’d caught him and was angry. Maybe he thought that he’d somehow ruined things between us.

“Timmy, it’s OK,” I said soothingly as I snuggled up behind him and put an arm around him. His sobs just got worse: huge wet, awful-sounding gasps that made his whole body shake.

I held him as tight as I dared. “Timmy, it’s fine. Really.” But he was inconsolable. I could hear the scratching in his throat as his bawling tore at it.

“Please stop, Timmy,” I begged, but it was no use. In desperation I tried the only thing I could think of to convince him I wasn’t upset at him: I cupped his groin with my hand. He was soft, of course. but the effect was immediate: his crying turned off like a tap.

“I’m so sorry,” he sniveled. “I just wanted to feel close to you.”

“I know. I know,” I said soothingly and I softly kissed the back of his neck.

“You’re really not angry?” he asked querously.

“No,” I whispered to him. “I thought it was ... lovely.”

Under my hand, I felt his penis start to twitch and grow and my clit responded in kind.

“Timmy,” I said, sitting up so that I could look at him. He turned to face me and his red, teary eyes clutched at my heart. “We can’t ... fuck--” The way his face crumpled at that point nearly broke my heart; I knew exactly how he felt. “But we can ... play.”

“Can I watch you again?” he asked. “Please? It was so, so beautiful. I’ve never seen anything like it.” I could hear the desperation and hope in his voice.

It wasn’t as if we’d be having sex, I rationalized it. I loved having him watch me and he loved watching me, so what was the harm. As long as there was no touching involved that would be OK, wouldn’t it? Just thinking about it again made my clit swell and pulse: I don’t think I’d ever wanted anything more.

“Yes,” I replied with a little smile when his face lit up with joy. “But this time I want to see you too,” I added with a little squeeze of what now felt like a very nicely sized erection.

I rolled away from him and stood beside the bed. With badly shaking hands I began to undo the buttons on my blouse.

“Now?!” he said incredulously with a huge silly grin on his face.

“Well, you look ready,” I said, looking meaningfully at the tent in his tracksuit bottoms. “And I’m feeling pretty much the same.”

Just baring my breasts to him again made me tremble and I fumbled at my jeans in my desperation to get naked for him again.

When I stood before him in just my panties I could see his dick bending under the pressure of being contained by his pants. I put my fingers into my waistband, grinned at the way his eyes jutted out on stalks, and then paused.

“Hey, no fair. I get to see you too.” I reminded him. Without taking his eyes off me he pulled the shirt off over his head and then together we pushed down our final garments.

I don’t claim to have been an expert at the time but I thought his cock looked beautiful. It was so hard it was pressed against his belly and his balls were tight and had only a thin covering of hair. My clit was going wild and the muscles of my vagina were squeezing down as if needing something to grip on.

I rearranged the pillows and sat next to him on the bed, trying to ignore the feeling of our bare arms touching. I heard him gasp as I opened my legs, and my whole pussy seemed to lurch as he pulled back his foreskin and I saw his shiny helmet for the first time.

I was very, very wet and I smeared it all over my pussy lips and clit hood while watching his fingers make his cock dance as he caressed the taught skin of his knob. Fighting down the urge to reach over and touch it, I had to satisfy myself by playing with my nipples which were hard and aching.

His movements became more urgent, his whole hand wrapping around the shaft and pumping just around the ridge below the glans. I loved watching him and I had to dip two fingers into my vag and rub over my clit, wanting to keep pace with him.

The sight of that seemed to spur him on and he cupped his balls, his hand moving faster. Neither of us could keep our hips still and our bare thighs kept brushing together. ‘No touching’ I repeated silently to myself even as his hot skin brushing against mine turned me on even more.

My fingers delved deeper and my thumb sought out my clit as I saw a drop appear in his slit. I was close now and watching him avidly. I was expecting it but it was still a shock when his hips made a sudden lurch and a jet of cum shot onto his belly. It was all I needed and my vag gripped my fingers hard as I began to cum as well.

I watched his convulsions, accompanied by more lovely spurts of cum, while my own tore through me and I absolutely loved it. I could feel his body shaking through our thighs, which had become tightly pressed together, and I savored that single touch knowing it was all I could allow myself and still retain any sort of control.

The closeness we felt from our naughty sessions was extraordinary and spilled over into our lives in general, bringing us much, much closer. I tried to tell myself that it was just a bit of sexy fun but I think we both knew it had become more than that. Much more than that.

The more often that we ‘played’ the more difficult I found it to restrain myself from touching him. I loved him so much by that stage that I just wanted to give myself to him in the most intimate way possible.

Inevitably one day I succumbed: I could resist it no longer and I leaned over and engulfed him. There was no conscious decision, I just became too weak to stop myself from doing what I knew we both wanted so much. I loved the feel of him in my mouth and the taste of him.

Of course, he wanted to pleasure me in the same way I had him, and I couldn’t refuse. I didn’t want to refuse, and his lips and tongue made me scream with delight.

The next day ... well, I’m not sure what would have happened. I was astride him, with his lovely erection tickling my tonsils, and he was sucking around my clit and lapping at it with his tongue. I was in utter heaven, feeling his body against mine and being able to run my hands all over him, when I heard Mom’s voice and we both froze.

“Oh God Alex, I’m so sorry” I turned my head and saw her standing in my doorway, her face bright red with embarrassment and her hand over her mouth. Then I felt Tim’s mouth leave my pussy and all hell broke loose.

“Tim! Oh fuck Tim, is that you?! Oh God, Oh my God!”

She ran from the room and I heard her pounding down the stairs. Tim and I disentangled ourselves and looked at each other in horror.

“Oh shit,” he said, softly. I grabbed a robe and chased after her. When I got to the bottom of the stairs she was on the phone.

“You’ve got to come home, they’re fucking...”

“Mom, please don’t do this,” I begged, knowing that if Dad found out this would rapidly go nuclear. “We haven’t actually--”

“Tim and Alex. Our son and daughter, that’s who!” My heart sank, knowing there was no putting that genie back in the bottle now.

I went back up to my room, where Tim had put his clothes back on, and gave him the bad news. Then I got dressed and we sat on my bed, hand in hand, waiting for armageddon.

“How could you? He’s your little brother for fuck’s sake. That’s incest.” he shouted.

“Really Dad?!” I shouted back. “That doesn’t seem to bother you when you get hard peeking up my skirt!” I knew I shouldn’t have gone there as soon as I saw his face turning the color of beetroot. But it was true: I’d lost count of the number of times I’d caught him perving at me like that.

“Dan?” Mom asked in a horrified voice.

“Get out!” Dad bellowed, ignoring her. “I won’t be spoken to like that in my own house!”

“Dan, come on, you’re not serious.” Mom said, trying to calm things down.

“I am absolutely serious,” he told her and then turned to me. “Pack some things and get out!”

I was so furious I couldn’t speak. I turned to storm out when Tim walked up to Dad and stood right in his face, or as much as he could being six inches shorter.

“If she goes I go,” he told him, his face every bit as angry as I felt. I saw that Dad was shocked.

“Don’t be silly Timothy. Go to your room and we’ll talk in the morning.” Dad said, putting his hand on Tim’s shoulder to steer him away. Tim shrugged it off violently, came over to me, and put his arm around my waist.

“I’m ... fucking serious Dad. If she goes, I’m going with her!”

“Fine!” Dad roared and stomped off to his den. Mom went after him and we heard raised voices from inside. I held Tim at arm’s length and looked at his red face.

“Timmy,” I said softly. “You should stay.”

“I mean it, Alex. I don’t want to stay here without you,” he said very seriously. And then he took both of my hands in his and smiled, a big honest happy smile. “I love you, Alex.”

Even though our lives were falling apart around us I couldn’t help but smile back. Tears were welling up in my eyes and I pulled him to me in a fierce hug. “I love you too Timothy, God help us.” We held each other for as long as we dared. “We’d better pack some things then,” I said finally.

I just told Mona that we’d had a huge row with Dad, and her parents were OK with us staying for the night. When we got there they wanted to go and talk Dad down but I managed to persuade them not to. I spent the night on Mona’s floor while Tim slept on their couch.

The next morning the enormity of our situation seemed almost overwhelming, but I had Tim to look after, so I just crushed my fears down into a small ball in the pit of my stomach and pushed on. I had a small amount of savings so we weren’t going to starve, well not immediately anyway.

My first priority was a job. We scoured the local paper and there wasn’t much that didn’t need any experience. In the end, I managed to get a job as a sales assistant in a clothes store seemingly on the basis that I dressed OK. It didn’t pay too much but beggars can’t ... etc.

Next was somewhere to live, after a celebratory pair of burgers that is. The same paper yielded a small, two-room apartment at only a mildly exorbitant rent. Tim waited in a coffee shop while I spoke to the prospective landlord. It was a bit of a dump but as before ... and it was available immediately. The deposit took a large chunk of my savings.

We sat down together at the tiny table in the kitchen area at the end of the day and did the rough math that we probably should have done to start with.

“We aren’t earning enough to be able to eat.” was the conclusion reached by my little brother. “I could get a job...” he suggested.

“No,” I said firmly. “Well, during the break maybe, but then you’ve got to go back to school.”

We sat in thoughtful silence for several minutes.

“There is something...” he began and then faded out as if unsure.

“Come on, what is it?” I said. “Any ideas are welcome at this point.”

“There’s this guy at school, his cousin ... no, this isn’t a good idea at all.”

“Spill, Timothy!” I insisted.

“She’s got a channel on OnlyFans ... she makes good money apparently.”

“I’m not sure anyone would pay to see you,” I said, more to give myself time to think than anything else.

“No, I meant--” he started to reply and then laughed. “Very funny.”

“So porn then?”

“Well, he says not. Nudity and ... you know, touching and stuff.”

“I’m not sure anyone would pay to see me either.” I mused out loud.

“Are you crazy, you’re beautiful! Not gross and slutty like most girls on the internet. Girl-next-door gorgeous, I’d-give-my-right-arm-to-see-her-naked type beautiful.”

I leaned over the table and gave him a fond little kiss. “You say the nicest things.”

“I could film you on my iPhone and edit it on my laptop.”

I have to admit that there was a real appeal to that idea. “Do you know how to edit videos?” I asked, and he looked all hurt.

“I’ve been filming and editing the videos for our RC events for ages now,” he said as if I really should have known that.

“Sorry, I never knew,” I said, and strangely the little pout on his lips added to the little tingle I was feeling.

“So I just take all my clothes off and you film it...” I asked and as I spoke the words they sounded better and better.

“Well...” he said, not quite meeting my eye.

“Well?”

There was a long silence as I guessed he was plucking up the courage to say what was on his mind. Finally, he lifted his head and looked at me.

“I’m sure there are lots of girls doing that--” he began, and then stalled when he saw me raise an eyebrow. “Not as beautiful as you, of course,” he added quickly.

“Good save,” I conceded, with a smile. There was another brief pause.

“The moment I fell completely in love with you was when I watched you playing with yourself that first time ... and cumming.” he said wistfully and with a dreamy, ecstatic expression.

I admit I was shocked. And turned on as hell. Here was my little brother suggesting that I should jill off to orgasm, while he filmed me, and then sell the tape. I think he saw me considering it.

“I’ve seen ... some porn,” he admitted, and I loved the pink flush suffusing his cheeks afterward. “Most of the girls fake it. I’ve never seen anything as beautiful as you ... when you came.”

I couldn’t restrain myself any longer. I stood up and held out my hand. He took it and stood up too. I began to move towards the bedroom. “Don’t forget your phone,” I told him and his grin made my pussy clench hard.

As I lay on the bed I was telling myself that we’d make the video just for us and then see afterwards how we felt.

“You first,” I told him and, as I lay there and he took his clothes off, I could feel my labia getting thicker and hotter. I was already very wet even before his penis sprang into view.

Then he began filming. With a conscious effort I put the video, and whatever might happen with it, out of my mind and just focused on giving Tim as much pleasure as I could.

I stripped for him, slowly and teasingly, showing him my breasts first because somehow they were desperate to be seen. He got so close I could feel his breath on my nipples and I got chills all over as I tugged them into full, aching hardness.

I loved the way I could see from the way that his penis reacted exactly what he liked best, and he followed my fingers as they traced a path downwards. My pussy was drooling as I brushed a fingertip up and down my lips and I heard him gasp as I opened my legs wider and delved between my buttocks.

The drips of precum leaking from his red and swollen cock made my mouth drool too, and the emptiness inside me just had to be relieved. His naked shoulders brushed the inside of my thighs as he got very, very close and the walls of my vagina clenched down on my probing fingers.

The urge to show him everything was intense and I used my other hand to pull up on my mons so that my little pearl popped out. Just the air on it was almost enough, and maybe he sensed that, because I felt him blowing on me and my whole body began to quake as I teetered on the edge. I began to move my fingers, making my clit pop in and out of its little hood and that was all it took to make me explode. Tim instantly moved up to my face and in doing so his thigh pressed my hands hard against my pussy. I clamped my thighs around his, to pull him in tighter, and the waves of intense pleasure crashed over me making me shudder and quake, over and over, until finally, I flopped back on the bed.

He put the phone down and I could see that he was shaking. “Jesus, Alex, that was incredible,” he said breathlessly.

“Shut up and fuck me, Timothy,” I ordered, but with a wide, wicked grin on my face and my legs spread wide.

The second he entered me it was like I felt whole, like a part of me had always been missing and now it was back, safe and sound in my pussy. I think it was as close to a religious experience as I’d ever known, and for an age, I just held him there with my legs wrapped around him and reveled in the feeling of his penis throbbing away inside me.

He didn’t last too long that first time but it was utterly beautiful anyway. The second time was a lot slower and breathtakingly wonderful.

We managed to shower together in the pitifully small cubicle and then Tim set about editing the footage. He had to send me out of the room in the end after I drove him mad, pacing up and down behind him.

We sat in silence as we watched the final result. When it was over we looked at each other.

“Do you really think people are going to pay good money to see that?” I asked, my voice coming out weirdly high and nervous.

“Alex, I’d pay to see it again ... and I was there!”

“But that cum-face...?” I pleaded, covering said face with both hands. He peeled them gently away and then kissed me.

“It’s the cutest thing ever!” he insisted leaning back and smiling at me fondly. I pulled him back into another, much longer kiss. And then we worked on making that face again. Just for us this time though.

The rest is kind of history. In the first month, we only earned enough to cover our shortfall and buy some better equipment. In the second we bought a small car and in the third, I gave up my job and we moved to a better apartment.

We weren’t stupid though, we knew it wouldn’t last forever: We were making videos faster than we were publishing them (no hardship there!) and putting money aside. I began going to a local college and studying Graphic Design.

Mom eventually came to terms with me and Tim being together, although, as I write this, Dad still hasn’t.

I won’t tell you the name we chose for my account on OnlyFans, but it’s not too hard to find if you look.

If you do find me I can assure you that none of the orgasms are faked.

The End
