Okay." Mark said. Then pulling a u-turn drove back the way we came. I didn't ask where he was going I was just happy to be with him. Reaching down I grabbed his hand and squeezed it tight. Mark drove through Cranston to an old mill complex pulling around back he drove up to a set of rusted metal gates with a pad lock. Mark hopped out quickly and grabbed the padlock which fell open in his hand. After pushing the gate open Mark hopped back in the car, pulled it through and closed the gate behind him replacing the broken lock. I realized where we were; the flats it was called, a notorious make out spot for teenagers and where I'm sure Mark had brought Krissy before dad let him start "sneaking" her in.

. "I'm sorry this is pretty sleazy." He said looking genuinely upset.

I smiled, my brother was so sweet sometimes, but we hadn't been together since the hotel and this nasty girl needed her little brother's cock in the worst way so I didn't give a shit where we were. I leaned over and kissed Mark hard grabbing the back of his head so he wouldn't pull away from me. There was no need, my brother responded with the same sense of urgency I felt. As he plunged his tongue into my mouth his hands were already undoing the top buttons of my blouse.

"Oh yes!" I groaned as his lips left mine to find my neck at the same time his left hand slid into the cup of my bra and found my nipple.

I dropped my right hand into his lap and started stroking his hard cock through his jeans. Mark had finished with the buttons and pushing me back against the door of the car pulled my bra down, allowing my tits to spring free. With a groan that sent a wave of heat through my pussy Mark attacked my nipple's sucking the left one into his mouth while his fingers found the right.

"Ohhh! Oh yeah, you miss your sister's tits little brother?"

"I miss all of you!" Mark said as he removed his mouth so he could suck on my other nipple.

I leaned back against the door panting as Mark worked my nipples, then moaned as his hand dipped under my skirt, through my stockings and panties and started rubbing my pussy.

"Damn," He whispered. "You soaked right through!"

"That's because your nasty big sister needs that big fucking cock of yours little brother."

Mark reached further up my skirt trying to get into the waistband of the stockings. I had a better idea, at least for now, as I wasn't kidding about needing some of that cock and right now where I wanted my little brother's cock was right between his big sister's made for cock sucking lips.

"We'll get those later." I told him as leaning forward I pushed him back over to his side and reaching down unsnapped his jeans.

"Put your seat back." I told him as I pulled his zipper down.

Mark pushed his seat back all the way and lifted his hips so I could tug his jeans and underwear down.

"Oh look at that cock!" I exclaimed.

Mark's huge dick was standing straight up and was already dripping. Wrapping my right hand around it I started jerking it off as I leaned over and kissed him. My brother let out a whimper as I started kissing his neck while stroking his throbbing cock. With my other hand I tugged on his shirt.

"Take this off."

Mark leaned up and stripped off the two shirts, as soon as he did I found his nipple with my mouth. I looked up, making sure my brother was getting a good look at the tip of my tongue flicking across his flesh. I winked then slowly trailed my tongue down his flat hard stomach and towards his swollen cock.

"Oh yeah sis." He groaned as I gave the tip of his cock a sweet little kiss.

"Yeah little brother? You want your big sister to give you a blow job in the car?" I swirled my tongue around the tip of his cock getting a mouthful of his pre cum. "Only bad girls do those things." I looked up at him and winking said;

"Good thing for you your sisters a nasty girl."

Taking the tip of Mark's cock I slowly worked the length of it down my throat swishing my tongue around the entire time. Mark was breathing heavy and reaching down he grabbed a handful of my long black hair.

"Mmm mmm," I told him, the humming getting another groan out of him.

As I started bobbing my head up and down in a slow steady rhythm Mark kept his hand in my hair guiding my head up and down his twitching cock.

"Get on your knees Sis."

Keeping his cock in my mouth I pulled my long legs up onto the seat one at a time folding them under me until I was kneeling across the huge front seat. Mark reached across with his right hand, sliding it underneath my skirt and panties and slipped his finger into my pussy to get it wet then finding my clit began gently rubbing it.

"Oh damn that's nice." I said removing his cock from my mouth. "That's it little..."

I was cut short by Mark, using my hair as a handle, shoving my mouth back onto his cock. I opened wide as he pushed my head down to take the entire length. After holding me there for a minute he started slowly pulling my head up and down his cock. I relaxed letting him take control of how I sucked him. I kept my tongue moving at the same time sucking as hard as I could. I moaned as I realized Mark's finger was stroking my clit in the same rhythm he was moving my head. Keeping my right hand around his prick I reached my left underneath me and finding my nipple began to roll it between my finger tips.

Mark and I were both moaning, his hips were beginning to come off the seat to greet my more than willing mouth and I was starting to rock back and forth into his talented fingers. Mark let out one of those adorable little whimpers and I could tell he was holding back from really pumping his cock into my mouth. I pushed my mouth off of him long enough to look up at him and say;

"Go on little brother, you just go ahead shove that big fucking cock down my throat until you come, you let you sister take good care of you."

With that I put my mouth back on the tip of my brother's dick and waited. Taking his cue Mark resumed pumping my head up and down his cock, but faster and harder this time. I groaned in pleasure around his cock as he also sped up his fingers on my clit. Mark began moaning continuously, bringing his hips up to meet my mouth. As he pumped faster and harder my mouth was stretched to the limit and my eyes were beginning to water as my brother fucked my face.

Just as I felt Mark's cock twitch in my mouth and the first shot of cum hit the back of my throat his fingers gave my clit a slight pinch and started shaking it back and forth. At that moment I gave my nipple a good hard pinch and started squealing around my brothers cock as my orgasm plowed through me. Mark was holding my head onto his cock so as I was moaning in pleasure I was still getting cum sprayed into my mouth. I heard myself making a whimpering gurgling noise that drove me wild oh you nasty fucking girl.

Mark let go of my head and I pulled it off of him letting a mouthful of cum out to splatter all over his cock. Damn that looked hot! Mark was leaning back against the seat panting. I sat up on my knees trying to catch my own breath.

"Damn I came hard." I told him. "I needed that."

Mark looked over at me and smiled.

"How about you hop in the back and take those damn stockings off?"

I didn't need to be told twice. I got out of the car with my tits hanging out of my blouse and quickly pulled everything off from under my skirt and after moving the seat climbed into the back. Mark had done the same thing stripping his jeans and underwear off in the cold winter air and getting into the back where, like I had, he got onto his knees.

I leaned against the window and raising my legs put them up on his shoulders. I was going to try to sit up more as Mark couldn't quite angle his head down to my pussy, but before I could Mark slid his hands underneath me and cupping my ass in them lifted me up off the seat and directly into his eager tongue which he plunged deep into my steaming pussy.

I squealed in delight as Mark ran his tongue up and down the length of my incredibly slick pussy. Each time he reached my clit he would do a quick circle around it before giving it a quick suck then trail back down again. As unbelievable as it felt it looked pretty damn good too as Mark's arms were bulging with the effort of holding me up and his face was glistening, covered in his big sisters juices. Mark once again shoved his tongue inside of me and held it still. Taking the hint I started pumping my hips moving and sliding his rigid tongue in and out of my pussy.

"Oh hell yeah!" I exclaimed. "Look at you, tongue fucking your sister!"

Mark then slid lower and slid his tongue into my ass getting another high pitched squeal out of me.

"Ohh you are naughty little brother!"

Mark's tongue found its way back to my clit where he swirled it around in tight hard circles. Mark's hands were busy holding me up so I reached down and spread myself open for him.

"Oh that looks so good sis!" He told me as his tongue ran across my clit and between my fingers.

Mark sped up the circles and as my hips began thrusting harder he fastened his lips around my swollen clit and started sucking it in and out, in rhythm to my movements. I removed my fingers from my pussy so I could play with both of my hard pink nipples. Once again as I felt myself on the edge, I gave them a pinch; that little jolt of pain sending me over the edge. This time without a mouthful of cock to stop me I through back my head and screamed long and loud, my hips thrusting hard into my brother's face, the scream died down to a soft whimper as the last waves of pleasure flowed through me. I jumped and I moaned as Mark put his mouth on my pussy and sucking hard came away with a string of his sister's cum on the tip of his tongue,

"Ohhh little brother." I said softly.

Goddamn I think I had cum even harder that time. And Jack thought he could give me what he needed. Please, my brother was ten times the lover he was. Then again I thought with a smile he did have a great teacher. My thoughts were stopped short as Mark keeping my legs on his shoulders dropped my hips to the seat and coming forward drove his once again hard cock deep inside of me and started fucking the shit out of me. My pussy was so wet that there was a wet sucking sound each time he thrust himself in and out.

"Oh Fuck yeah!!" I cried out as Mark hammered away at me.

I lifted my legs off his shoulders and placed my feet flat against the roof of the car(,) my red toe nails and Ivory skin looking incredibly sexy on the black upholstery. Not as sexy as my brother however. Even though it was winter the heat was cranked up in the car and with the sexual Olympics we had been having Mark was covered in sweat, making the muscles in his chest and arms stick out even more. Reaching out I put the palms of my hands on his chest and started caressing his flesh running them down across his flat hard stomach then back up where I gave his nipples a playful pinch.

Mark took his feet and pushed them against the window(,) lifting himself off the seat and holding himself in the air like that continued to drive himself into me. Holy fucking shit! I thought as I looked at the muscles in his thighs and calves bulge along with his forearms and biceps. Jesus Christ he's strong, as even in that position he was fucking me hard enough to get a yelp out of me with each thrust. After another few pumps Mark dropped back down to his knees and pushing my legs back even further delivered several unbelievably hard thrusts.

"Oh my fucking god!" I screamed as my brother pounded the shit out of my poor little pussy.

Mark drove into me several more times before letting out that little whimper again and filling his big sisters pussy with another amazing amount of hot cum. Mark looked down at me sweat dripping from his face. I put my arms around his neck and pulled him down into me.

"Come here little brother." I said softly.

Mark let his weight go and slid his arms underneath me. I lowered my legs but kept them around his waist completely wrapping him up into my body. We laid there holding each other tightly Mark was still breathing heavy in my ear and I could feel his heart pounding against my chest.

"Easy baby." I whispered as I started playing with his hair.

"I missed you Sis."

"Me too little brother that's why I had to call, Mark I had to. I needed you bad."

"Yeah well this feels great but we gotta get dressed." Mark said pulling himself away from me.

As much as I hated to let him go, I certainly wasn't going to argue with him especially after last weekend's scene at the hotel. I was pretty much still dressed so it only took me a minute to pull my bra back over my tits and button my blouse.

I watched shaking my head as Mark opened the car door and stood out there completely naked on a twenty degree day and slowly got dressed. I have to say the steam coming off of his powerful body looked amazing. I would have to use it in a painting sometime. Mark finished dressing and after tossing my panties and stockings back to me reached into the glove compartment and removed something I couldn't see. Mark climbed into the back seat with me.

"I'll tell you what I think I missed more than that," Mark said. As he spoke he put his back up against the back window and after sliding one of his legs along the length of the seat put his arms out. "Come here Sis." He said softly.

Oh god how I needed that! I turned around in the seat and slid backwards until I was between Mark's legs and my back was against his chest. I slid down a little more so the back of my head was resting in his shoulder. Mark wrapped his arms around my waist and kissed the side of my neck. Oh this felt so good! I put arms on top of his and sighed settling back into him.

"Shit," Mark said. "Hold on." He removed his arm and picked something up off the seat and put it in front of me. It was the timer he used when he worked out.

"What time you say you were working until?"

"Six."

As amazing as it was I already felt drowsy between the incredible sex and how good Mark felt I knew I would sleep.

Mark set the timer for ninety minutes then putting it down on my lap wrapped his arms back around me.

I closed my eyes and was almost out when Mark whispered;

"Meg?"

"Yeah Mark?"

"I... I think your father's going to tell me to leave."

"We don't know that Mark. Mom said she'd work on him and the longer it goes I think the better I mean he would have done it right away if he didn't have doubts."

"Yeah or we all made him feel like he was wrong."

"It'll be okay Mark." I squeezed his arm reassuringly although I wasn't all that sure myself things would be okay.

"You're all I have Meg." Mark said in a tone that brought the tears back again.

I didn't answer right away. Partly because I really didn't know what to say, but mostly because I was so tired I couldn't think straight. As much as I wanted to say something comforting I needed to sleep, get my head clear and go from there. As if reading my mind Mark whispered;

"I'm so tired sis."

"Then go to sleep little brother." I said softly.

I waited to see if he would say anything else but within a couple of minutes Mark's breathing slowed and deepened in my ear and I knew he was asleep. Closing my own eyes I could already feel myself drifting. Four days of fear and stress were forgotten as I wiggled myself back a little more nestling into Mark's chest even more. Suddenly everything felt like it was okay just as I knew it would.

I awoke with a start as the watch began beeping in my lap. I hit the button then taking a deep breath I held it for a moment before slowly exhaling. Damn that was a fast hour and a half. I must have gone right out. I didn't even dream about the hotel as I had the past few nights. More importantly I didn't have the other dream the one that had been plaguing me all week, and up until a year or so ago a good part of my life. Of course the reason for that was lying behind me holding me in his arms. On that note I realized Mark was still sleeping I can't imagine how exhausted he must be to sleep through an alarm, like myself a pin dropping could wake my brother.

Looking down at the watch I saw it was 5:30. We should be going so I could get to Vinnie's in time to pretend I left at six, god knew my father probably had the route home timed out. After listening to my brother's steady breathing in my ear and enjoying how good it felt to be close to him again. I figured screw it and set the watch for another half hour. I didn't think I would fall back but the last thing we would need is to fall asleep and wake up in the middle of the night. Besides this way Mark could sleep a little longer, I'm sure he had been getting less sleep than me as he wasn't getting any "help" like his big sister was.

On that note I frowned, the last three nights I had told myself I wouldn't drink to fall asleep, but each night I had given in, just as I had given into Jack's offering it to me after work every day. I didn't want to but it really did make me feel better. After years of doing very well leading a normal life with parents who truly loved me and of course my beautiful little brother who loved me in every way, I had begun to feel that old empty feeling coming back, that feeling that no one else except Mark seemed to understand. The only time it seemed to go away was if I was with my brother or if I took the edge off with drinking. Gently moving Mark's hands from around my waist I sat up.

Mark opened his bloodshot eyes for a moment then closed them again as I gently caressed his cheek. My brother made that adorable little cooing sound and turned his head into the seat. I wasn't sure if he had ever really woken up. Looking at him I wondered what would happen if my brother was no longer around to be there for me. What if dad threw him out who would I turn to? As watched my brother sleep, I knew that I would have to find away to convince my father to let Mark stay. My little brother needed me. Although as I leaned forward and rested my head on his chest I was beginning to realize not nearly as much as his big sister needed him.
