I pulled my mouth from my brother's and burying my face in his neck let out a series of barely suppressed squeals as my orgasm flowed through my body causing my pussy to contract around my brother's thick cock and causing him to moan as well. Mark continued to stroke my clit and squeeze my nipple, making sure that his sister came long and hard. I finished with a long shuddering moan and slumped back into Mark's chest.

"Damn, little brother." I groaned as he continued to fuck me.

"Yeah you like that sis?" He asked in my ear as he started fucking me harder.

"Like it? Tell you what little brother you can have it anyway you want it right now."

I reached down and grabbing the base of my brother's cock began jerking it off into my pussy as he fucked me.

"Ohhh," Mark moaned. "Oh I love when you do that."

"I mean it little brother anyway you want it this morning! You want me on my back? My knees? You want me to suck you off? Just take it little brother!"

"Sounds good to me!"

As Mark spoke he pushed me onto my stomach and rolling over on top of me slid his arms underneath mine and lying on my back propped up on his elbows started pumping his hips into me hard and fast.

"Oooh that's so fucking deep!" I gasped.

This was an odd position but a nice one, Mark couldn't fuck me as hard as he could doggy style but the angle seemed just as deep and I enjoyed feeling his body on top of mine. Mark had stretched his arms all the way out and reaching out my hands found his and linking my fingers through his held them tightly as he thrust his massive cock in and out of my sopping wet pussy. My brother wasn't going slow but he wasn't fucking the shit out of me either and I found the pace quite enjoyable. My legs were stretched out as well so I was pretty much just lying relaxed on the bed as Mark had his way with me.

My brother's face was just behind my ear and I could hear him moan with every thrust.

"Go ahead little brother." I said softly. "Take it. It's all yours."

Mark moaned louder and started fucking me harder and faster.

"Yeah you like me telling you that?" I asked. "That your sister's pussy belongs to you? It does you know, any time any way little brother." I paused to squeal as Mark really started driving himself into me.

"Yeah that's right Mark go ahead and give it to me! Claim your sister's pussy! Make it yours just go and... ohhh yeah!"

My brother's cock exploded into my pussy; sending his warm sticky cum deep up inside of me where I loved it the most. Mark continued to give me long slow strokes as he emptied himself into my greedy little pussy, as he did he let his weight go and was breathing heavy directly into my ear. When he finished I clenched my pussy around his cock several times milking him and making him groan in pleasure.

"There you go baby." I whispered. "You give your sister every last drop."

We both sighed and Mark kissed the back of my neck before rolling off of me and lying on his side. I turned over on mine so that we were facing each other and smiled at him.

"Damn that was nice little brother."

"Yeah, even though you were mean to me last night. " He said grinning.

"Oh please," I told him. "You're the one that left my ass so red last week I couldn't sit at work."

Mark smiled and laughed. I smiled back at him. Our faces were only a foot or so apart and at the moment his multicolored eyes had shifted to the greenish shade that I liked best. I shook my head and told him;

"Little brother you do have the most beautiful eyes I've ever seen."

Mark smiled shyly and put his head down but not before I saw he was blushing. How damn cute! I thought and that shy little smile the one that no one else ever got to see.

"I love that smile." I told him laughing.

"And I love that laugh." Mark said looking back up at me.

Our eyes met and I stopped laughing. As we stared into each other's eyes I felt as if something was different between us. It was if I somehow felt even closer to Mark than I had before. Mark was looking at me oddly as if he felt it to. I wanted to make a joke or say something but found myself speechless, just lost in my brother's gaze. After a moment that seemed like an eternity Mark leaned forward, his lips parted to meet mine.

I felt my heart start to race but didn't understand why it's not like I hadn't kissed my brother before. Hell we had just made out while we were having sex a few minutes ago. As Mark lowered his head down to mine and his hand slid up behind my hair I turned my head to the side my own lips parted but rather than meet him halfway I closed my eyes and waited. I felt my brother's lips brush softly against mine and rather than lock into a kiss he slid his mouth lightly across mine teasing my lips with his.

"Kiss me." I whispered against his lips.

Mark kissed me twice; once so lightly that I barely felt it the second one wasn't much firmer but was amazing. It started with our lips barely touching then with each small kiss Mark pressed his mouth more firmly to mine. My heart was pounding and I realized I had goose bumps. We continued to kiss at that pace no rush no hurry just enjoying the moment. Was this how he had kissed Krissy I wondered, if it was she was even luckier than I had thought.

Finally after what seemed an eternity Mark broke the kiss and we opened our eyes. My brother had a strange look on his face and I had a feeling I did as well. Once again I found myself speechless but Mark still holding the back of my head whispered;

"You're so beautiful Megan."

This time it was me that blushed. I felt nervous and excited as if I had just been kissed for the first time, as if Mark wasn't my brother that I shouldn't even be with but more like a... boyfriend? No that was wrong Mark and I were forbidden lover's we weren't in love we couldn't be, it could never work. I looked at Mark, unsure of what to say or how to react, I mean what had just happened?

The two of us jumped at the sound of the hall way door banging and I could hear the heavy steps of my father coming up the stairs. Mark quickly hopped out of my bed and grabbing his pants gave me a quick kiss on the forehead and cutting through the bathroom went into his room. A moment later I heard Dad knock on his door and ask him if he could come downstairs and give him a hand moving some junk in the garage.

I got out of bed and figured since I had a few hours before work that I would do some painting. A few weeks ago Dad had surprised me by converting the small attic space into a studio for me, even running some pipes so I could have a sink and adding fluorescent light fixtures. This of course was before he had found out about my grades and had become another thing that I apparently didn't appreciate. Tossing on one of the ratty old night shirts I kept just for painting. I went out into the hallway and reaching up pulled the rope that brought the attic stairs down.

"Come on Mark you don't have to be pretty to move a damn fridge!"

I turned to see Dad leaning against the wall outside of Mark's room waiting for him. Dad looked over at me.

"Hey Dad." I said simply.

"Morning Megan." Dad replied.

We looked at each other for a moment, as little as a couple of weeks ago our good morning always consisted of my kissing him on the cheek and dad telling me I was getting to old to do that but then following it up with he would never complain about it. Now however it seemed we were barely on speaking terms. I gave him a forced smile then started climbing the ladder to go up to the attic.

"Hey Megan?" Dad called.

I shook my head. Ever since our last argument I didn't even get "hon" anymore, it was first name basis. Hell dad had been nicer to Mark the last couple of weeks.

"Yes dad?"

"If you're going to be climbing the ladder you should be wearing pants."

I glanced down and realized that my black panties were showing. Good thing I had decided to put underwear on I thought.

"Sorry I didn't think anyone here was interested in my ass." I told him.

"Don't get smart Megan it's about respect, you remember that word right?"

"Yes sir sorry sir." I replied. "Would you like me to change?"

Dad rolled his eyes and shook his head. I started to head up when he stopped me again.

"What are you doing today?"

"I have work from one to seven."

"And after that?"

I bit my tongue and spoke as calmly as I could;

"I was going to see if Betty was around but if not I might keep Mark company at Mitch's."

"I don't think you should be hanging around at a bar Megan you don't need the temptation."

"My brother's the bartender; you think he'd get me drunk?" Before Dad could reply I added;

"Besides Mom said I can go as long as Mark's there, I mean Christ he doesn't even let guys talk to me let alone give me drinks."

Dad looked as if he wanted to keep it going but sighed and said;

"You're right Mark wouldn't let you get into trouble."

So much for can't lie to me I thought again.

"Who knows," Dad continued, "If you hang around with him long enough maybe you'll see what he's been doing right."

That was a shot and I wasn't going to ignore it, but just as I was ready to reply Mark came out of his room. I could tell by the look on his face he had been listening and had come out to stop things from going downhill.

"Well if it ain't the good kid." I said giving Mark a fairly convincing dirty look.

"Well good morning to you too sis." My brother replied.

Ignoring him I started up the ladder when I had gotten to the top I heard Mark call;

"Hey Meg?" "What Mark?" I asked as I looked down at him and Dad.

"Put some pants on will you?"

Trying hard to keep a straight face I looked away and was going to go up, but when I head dad laugh I looked back down and said;

"Hey you two!"

When they looked up I reached down and pulling my shirt up over my hips slapped my ass with the other hand and said;

"If you don't like it don't look!"

My father yelled something but I quickly scooted up the last couple of rungs and after pulling the stairs up behind me also pulled the drawstring up so no one could come up. I could hear dad yelling my name so I went over and turned the radio on and cranked it. After a couple of minutes, during which I stood there stewing about how my father had just ruined a beautiful morning, I turned the radio down low and walking back to the stairs let the string back down so it wouldn't look like I was hiding anything.

Going over to the small fridge Dad had put up there I grabbed a yogurt and a banana and sitting down on the stool looked at my latest painting as I ate. Once again my brother and I were the subjects but unlike the other this one was full size and it was just us. Taking an 8x10 of each of our faces I had cut them in half and taped them together so it was the right side of my face and the left of Mark's.

I had spent the last two weeks painting that image and when it was finished was once again amazed at our resemblance, with the exception of Mark's eye color and darker skin tone we're all but identical. I had shown Mark who had rolled his eyes and complained that he didn't want to look that pretty so I had painted in the five o clock shadow look he had been sporting lately to make him happy.

Once our faces were finished I had drawn a jagged crack down the middle as if it were a broken picture frame. Putting the empty yogurt container down I opened up a couple of bottles of paint and spent a half hour or so touching up our eyes, lips and also added some depth to the crack. When I was finished I sat back and using red paint wrote the title at the bottom right corner;

Broken.

Once again signing Decosta at the bottom with a sharpie I sat back and looked at the painting. I was going to use it at the next showing at school. As I stared at my brother's side of the painting I thought back to what had just happened between us. Mark had felt it as well, I knew he had. Question was what exactly was it? I loved my brother with all my heart but it was as my brother. Or was it? After all we had been separated for years so maybe it was different.

On that note maybe it wasn't the fact that Mark was my brother that made me trust him enough to do all the things I couldn't with other guy's, maybe it was an emotion other than trust. My mind now spinning I kept coming back to how damn good Mark felt in bed, not just the sex but the way he held me. It was the kind of stuff you read about in those shitty romance novels. Could there be something between us? Even if there was what could we do about it? Everyone knew we were brother and sister and the folks! They would know I had lied and...

I stopped my mind from racing. I really didn't know for sure what was going on. After all maybe this morning was just some kind of fluke. Mark missed Krissy and the affection she had shown him and I... well I had never had it and desperately wanted it. Maybe as usual we were just giving the other what we thought they wanted. Then again I thought as I shifted my gaze from Mark's face to the jagged crack. What if we really were two broken halves to the same whole? What if our hearts fit together the way I had painted our faces?

Closing my eyes I envisioned my brother's face inches from my own, his lips parted and those amazing eyes staring longingly into my own. In my mind my brother spoke the words no man had ever said to me;

"I love you Megan." That's right he would say my name not Sis or my sister but Megan.

Still with my eyes closed and feeling kind of stupid but unable to help myself I whispered the response that I so badly wanted to say to someone;

"I love you too Mark."

I have to say I liked how it sounded.

Note from the author; Once again thank you to everyone who is still following and commenting on this series! To address the question I am hearing more and more with each chapter I am going back to the present shortly. You are reading 18 and 23 will bring us back to the here and now and Megan's dilemma of whether or not to accept Mark as her elusive "One". Also revealed will be why Doug now hates Mark as well as Megan's last days as an addict, how her engagement ended as well as the night that she and Mark are not supposed to ever bring up.

Trust me I am well aware that I have probably spent too much time in the past however I always saw this as a 3 part series with the past being part 2 and the finale as part 3. A big part of what I am trying to show is why M/M have not been a couple their entire lives as many people have asked me. Also please keep in mind that I plan on self publishing this series at the beginning of next year and am putting all of this up for feedback to see what to keep or not to keep. In the end for those of you who are unhappy with how much time I am spending getting back to the present please keep two things in mind:

One; that many of the small seemingly meaningless things I have mentioned will play into the end of the series and two; I am an amateur writer who is not getting paid for this I am doing the best I can with no experience whatsoever to fulfill a dream of finishing a novel. Having said that once again thank you to those who continue to support me and for those who have lost patience all I can say is you will miss out on a hell of an ending.

One final note; mixed in between chapter 23 and 24 will be a one shot story; Siblings with Benefits Lex Talionis which will chronicle the oft mentioned showdown between Mark and his abusive foster father Max. It will be pretty long and will go under novels/novellas and although there will be several sexual encounters it is a very story driven look at Mark and his inner demons. The story will also carry a warning for graphic violence. The end will not be pretty and honestly the entire thing will really only appeal to true fans of the series. Once again several minor things in it will feature into the very last chapters.

As always thank you for your comments good bad or indifferent I take them all seriously and reply to all that send a return e-mail. Sincerely Mike (Lovecraft68)

I am enjoying the story as it is written . It doesn’t bother me that much of the fucking takes place in the past as it really details why both brother and sister are the way they are. Knowing that there are many more adventures makes it much more interesting to read about how the past leads to the present and maybe even the future. If you plan to turn this into a book, you really need a good proofreader to help clean up the mistakes that are evidence that you don’t know any better.

I have really enjoyed this series. I keep rooting for Megan and Mark to realize that they are indeed the Love of esch others Life, I would like to see their sex lives turn to more romance and less abusive! Less of the feel of almost hate fucks.

I'll be honest, when I started this story I thought it was a stroke piece, the sex is hot and it's not super corny like most stories on here. But fuck me dead if you didn't weave a god damn tale in there. While I'm not super stoked on the huge amount of time spent in flashback, as I usually don't enjoy flashback as a plot point anyways, I wouldn't say it necessarily takes away from the story, but doesn't quite add as much as I think you were hoping for.

Maybe if you weaved the past and present together or something it might come together more, but it just feels a little disjointed right now, not bad just... Like it's been so long I almost stopped caring about the present and this is the present now you know?
