"What's this? A loaner or something?"

Mark smiled, and taking my hand, put a set of keys in it.

"No sis, this is your car."

I stared at him speechless.

"No Mark," I told him. " You... I mean you've done so much for me already and I..."

"Oh please Meg," Mark waved me off. "Its six years old and I got a good deal."

"But Mark," I continued shaking my head. "You paid for most of the clinic and..."

"It's only money sis." Mark said putting his arm around my shoulders. "You're the most important thing in my life so just say thanks and leave it alone." He laughed.

"Hell when you're a famous artist, you can buy me an old clunker, and call it even."

I wanted to say I couldn't take it, but looking at it I was overwhelmed by the simple thought of I had a car! I looked at Mark and just found myself smiling so hard my cheeks hurt.

"This is surprise number one sis." Mark said and looking at me laughed; "Well you going to get in and drive or what?"

I shook my head and passed him the keys.

"You drive I'm too excited!"

Mark laughed again, and after taking the keys and tossing my suitcase in the trunk, opened the door for me. I giggled like a little girl, and as I got in I made sure to hike my skirt up almost to my hip.

"Damn," Mark said shaking his head. "Sis you are looking good!"

Mark closed the door, and after getting in, pulled away. We were silent for a few minutes as I looked out the window smiling at nothing in particular except the thought that I would be sleeping in my old room tonight. Mark turned down a side street to cut off the traffic and as he came to a stop sign I looked over to see him looking at me intently. I gave him a huge smile, which he returned then, as his smile faded, he reached out and gently touched my cheek. I leaned my face into his hand and as I did our eyes met.

Mark's eyes were that beautiful shade of greenish gold that I loved and as I looked into those eyes I was aware of my brother leaning slowly towards me, his lips beginning to part. My heart began to beat faster, and my breathing picked up as I turned my head to the side, and parting my own lips closed my eyes, and waited for the kiss I had been dreaming about for months. I was not disappointed as a moment later I felt the gentle touch of my brothers soft lips brush against mine.

We both moaned softly in our throats, as Mark's lips pressed harder, and the moans became louder as I opened my mouth to let my brother's tongue in to caress my own. I leaned in, and kissed Mark even harder, pushing my lips hard into his as our tongues continued to play. I felt Mark's hand slide behind my head and begin to run through my long hair. Mark's other hand slid from my cheek down the soft skin of my neck and started to undo the top button of my blouse. I felt a wave of moisture flow through my pussy, and was just reaching for Mark's crotch, when a horn blared behind us.

Mark and I both jumped as we had been so caught up in each other we had forgotten we were in the middle of the street. Mark gunned the motor and peeled through the intersection. As we drove down the street I noticed we were going by the old building that contained self storage units. The back gate was always open, but there was never anyone there. Of course the reason I knew that was a couple of years ago when I was selling myself that's where I would tell the johns to go park and...

Forcing that "humbling" thought from my mind, a trick I was certainly going to have to get used to doing, I looked over at my brother and said;

"Pull behind the U-haul building."

"What?" Mark asked glancing over at me.

"I need it Mark." I told him, and leaning over reached out and squeezed his huge cock through his jeans. "Oh how I need my little brother's cock."

Mark looked at the clock on the dash of the car.

"We have a half an hour to get to the folks place and Marchetti's sis."

"So we'll be late." I told him beginning to stroke my hand up and down his cock.

I was so wet I could feel the crotch of my panties sticking to my pussy. It had been close to a year since my brother and I had decent sex together, I didn't even want to think about the week before my stay at the hospital and before that...

"Meg we can't, Denise was all but begging me to take her to come get you. I can't make her wait."

"Mark please!" I begged. "We won't have a chance until next week!"

I squeezed his cock hard enough to get him to moan then started trying to unsnap his jeans.

"Just a quickie Mark, we'll hop in the back, and you can just fuck me It's been to long I..."

Mark looked over and smiled.

"Come on sis you can wait a few more hours."

"Hours?" I asked. "Mark we were talking last night we can't get to your place until..." I trailed off as Mark's smile widened.

"Look in the back seat sis."

I looked in the back and saw a large duffel bag.

"So? It's a bag I don't understand."

We had come to a red light, and looking over at me, Mark said;

"Denise called me this morning, and said she knows I feel bad that you can't come stay with me for awhile, and thought that maybe it would be fun for me to spend the weekend. After all they still have my old room set up as a guest room. Denise said it would be like the good old days."

"Are you kidding?" I asked.

"Nope," With a wicked smirk Mark continued; "That's right sis, the folks will go to sleep, and then your naughty little brother is going to slip into his big sisters room and do nasty things to her." He laughed. "Just like the good old days!"

"Oh my god Mark!" I exclaimed as what he was saying fully hit me. "We can sleep together tonight and tomorrow tonight!"

"And wake up together." Mark said, then leaning over and kissing me on the neck whispered softly in my ear. "Megan I can't wait to wake up with you in my arms."

Oh how good that sounded! The light changed, and as Mark pulled away, I sat back and sighed;

"I suppose after this long what's another few hours?"

Mark nodded then, as we got onto the highway, dropped his hand onto my knee and slowly trailed it up under my skirt. I let out a soft moan as my brothers hand made its way all the way up to the top of my thigh. A much louder moan escaped me as Mark started rubbing my thigh, causing the edge of his hand to rub along the crotch of my panties stroking my desperate pussy through the silky material. I clenched my thighs tightly around his hand and whimpered;

"Oh little brother please don't tease!"

Glancing over Mark winked and said;

"Open your legs sis and I'll take the edge off."

I certainly didn't need to be told twice. Sliding my heel off I lifted my right leg and after placing my foot against the glove compartment reached down and pulled my red thong, the one Mark had brought me last week, to the side.

"Oh yesss!" I moaned as my brother instantly plunged two fingers inside of my sopping wet pussy.

I began letting out soft sighs of pleasure as Mark started to slowly pump his fingers in and out. All I'd had up there in the last six months had been my own finger and my pussy felt delightfully tight against my brothers fingers, leaving me to wonder how incredible his massive cock was going to feel in a few hours. Those soft sighs turned into a long loud moan as turning his wrist into what had to be an awkward angle Mark placed his thumb on my swollen clit and started to rub in small circles.

"Ohh that is soooo nice little brother." I breathed out as I leaned back further into the seat and started to rock my hips back and forth.

Mark cut across two lanes to get into the right hand lane and as he slowed the car down his fingers and thumb sped up as did my breathing and moaning. Reaching down with my left hand I grabbed Mark's forearm and squeezing it groaned at how good the hard muscles there felt. Of course they felt nowhere near as good as the hard muscle I was truly anticipating but a turn on nonetheless. Feeling my legs already starting to tremble in anticipation of the first orgasm that wasn't from my own hands in half a year, I took my hand away from my thong and undoing one of the buttons in the middle of my blouse slid it inside.

I closed my eyes and leaned my head back on the seat as I grabbed the barbell in my nipple through the bra and started to wiggle it back and forth pulling the sensitive skin there just enough to give me that delicious hint of pain that drove me wild. I wasn't the only one into a little pain as I heard my brother whisper;

"Squeeze harder."

I dug my long fingernails into Mark's flesh as hard as I could and felt my pussy flow even more as I heard him let out a sharp gasp that had hints of both pleasure and pain in it. Mark also began driving his fingers into my pussy harder and faster.

"Oh you like it rough don't you, little brother?" I asked in between moans.

Mark's answer was to slip one of his fingers from my pussy and without warning drive it hard up into my incredibly tight ass. That sent me over the edge and dropping my leg down to pin Mark's hands between my thighs I threw my head back over the seat and let out a long loud wail of pleasure. For the last six months I'd had a roommate and had to cum biting into a pillow so now just the sound of my own voice crying out in ecstasy was enough to make me scream again. I dug into Mark's arm even harder as wave after wave of intense pleasure crashed through me.

The best part was, even as I was bucking my hips up and down off the seat, all I could think of was that this was just my brother's hand; the thought of what he was going to do to me with his tongue later kept me cumming even longer and harder. With one last long shuddering moan my body relaxed and I slumped back into the seat gasping.

"Holy shit I came hard." I panted out.

"Guess so," Mark said, then looking down added; "I might have to change into a long sleeve shirt."

Looking down I saw that I had dug my nails into Mark's arm so hard that there were five unmistakable nail marks three of which were beginning to bleed.

"Damn, I'm sorry little brother I..."

I trailed off as my gaze had dropped further down into Mark's crotch to see that not only was his enormous cock straining the material of his jeans, but there was a small wet spot where the tip of his cock was dripping. Apparently I wasn't the only one who desperately needed something. Looking up from his crotch I saw Mark bring his hand to his face and rub it under his nose. As I watched, totally turned on, Mark sniffed and rolled his eyes back in pleasure from the scent of his big sisters pussy. Now what kind of sister would I be if I didn't help him out after that? Reaching down I once again grabbed Mark's cock through his jeans.

"Ooooh someone misses his big sister." I cooed.

"Like you said Meg, don't tease."

I looked up and seeing that we were still several exits from my parents house, smiled and leaning over and kissing Mark's neck, I whispered;

"Well one good turn does deserve another."

With that I reached down reached down with both hands, and after unsnapping Mark's jeans and pulling the zipper down, I reached inside and fondled my brother's huge cock through his underwear. Mark slowed down and lifted his hips up off the seat so I could tug his pants down far enough to be able to reach in and remove his cock. I groaned at how good Mark's huge dripping prick looked as it sprang free. Even though I had just cum I could feel my pussy getting worked up again as squeezing his throbbing cock I started to slowly pump it up and down.

"Oh shit that feels good." Mark groaned.

I brought my hand up to the top and covering the head of Mark's cock with my hand, squeezed then twisted, rubbing his sticky pre cum across the sensitive head of his dick. The car suddenly surged forward as Mark's hips twitched and his leg kicked down.

"Easy little brother." I said laughing

I stopped laughing however as once again my eyes returned to my brother's enormous cock, which was so swollen the tip was turning purple.

"Aww," I said. "Has someone been hard for the whole ride?"

"Oh yeah."

"Yeah? Then you must need to cum as bad as I did then."

"Hell yeah I ...ohhh yeah sis just like that." Mark groaned, as while picking up the pace with my left hand, I brought my right hand around, and slipping it underneath, fondled his balls.

Mark slowed the car down even more, to the point where people were beginning to go around us. I'm sure my brother didn't mind as it gave his big sister more time to jerk off his amazing cock. I was leaning into Mark and as I continued to stroke him he put his arm around my shoulder and taking his eyes off the road for a moment gave me a quick kiss. I leaned further into him as bringing my hand up I started pumping his huge dick with both hands.

"Oh damn Meg," Mark moaned then added; "You are still a nasty girl aren't you?"

At this point my brother's cock was glistening with his own sticky fluid, and was so hard I could feel it pulsing in my hands, at that moment I realized it looked to good not to taste, and besides my brother deserved more than just a hand job from his big sister.

"You think this is nasty little brother?" I asked. "How about this?"

With that I quickly dropped my head into Mark's lap, and in one smooth motion, hungrily took Mark's massive dick deep into my more than willing mouth.

"Goddamn sis!" Mark gasped and I felt the car surge forward again. "Shit were in public people couldn't see my hand down there!"

I pulled my head from his lap long enough to say;

"And all they can see now is the back of my head; all anyone knows is the bad boy attorney is getting sucked off by a hot brunette now watch the road little brother!"

Without waiting for a response I went back to eagerly devouring my little brother's cock; taking him so far down that my lips were touching the base of his shaft. I held my head there enjoying both the sound of Mark's moaning and the feeling of having my mouth stretched to the limit with cock, and not just any cock, but my beautiful little brother's cock. I gave my head a shake causing both another surge of speed through the car, as well as more moisture flowing through my pussy.

Realizing that as much as I wanted to enjoy my brother's magnificent prick we were only a few minutes from my parent's house, I started bobbing my head rapidly up and down, taking Mark's cock all the way down each time. I felt the car slow and adding my hand under my mouth started jerking Mark off as I continued to blow him as if it were a competition. I could feel Mark's leg begin to shake and felt the cars speed dip even more as he got closer and closer to cumming.

I jumped at the sound of a horn blowing next to us, and realized from the sound of it that it must be a tractor trailer driver who could see down into the car. I felt a moment of panic at the thought of I had just been seen giving my brother a blow job in public. That panic however was quickly replaced by a surge of wetness through my pussy, as I realized that I was right, no one could see my face and this guy had no idea that the dirty little slut sucking Mark's cock was really his big sister. I moaned around his cock as I thought; oh Megan you are a nasty girl!

Apparently I wasn't the only member of my family who was nasty, as when the driver blew his horn a second time Mark grabbed a handful of my hair, and started roughly shoving my head up and down harder on his cock. My pussy gushed between my legs as I heard the horn go off a third time and it wasn't the only thing going off as I heard the car's engine roar and as it surged forward Mark's cock twitched in my mouth, and a huge spurt of hot cum sprayed into the back of my mouth and down my throat.

Mark's hand relaxed on the back of my head as I continued to suck and jerk his cock. With each stroke of my hand I was rewarded with another shot of my brother's sticky fluid shooting into my mouth. Mark was gasping and moaning as I continued to milk his cock. I moaned myself as greedily sucking hard on the tip I managed to get a few more drops of the cum I had been dreaming of tasting for the last few weeks. I sucked Mark down one more time then as I started to raise my head Mark put his hand on my shoulder and said;

"Keep your head down a minute."

I felt the car speed up then a moment later felt it begin to turn.

"Okay." Mark said as he moved his hand.

I looked up to see we were going around the exit, Mark had kept my head down so there would be no one on either side of us when I popped back up. When he came to the stop sign at the end of it I reached out. and grabbing his chin and turning his face towards me. opened my mouth wide then closing it said in my best little girl voice:

"All gone!"

Mark laughed and shook his head as he lifted his hips and fixed his pants.

"Damn sis, I forgot how good you are at sucking cock."

I laughed loudly and asked;

"Hey Mark, you think they make hallmark cards that say that?" I got my laughing under control and said in serious voice;

"Sis, although were miles apart I can still picture your lips around my cock and..."

I lost the battle and started laughing again and I had to say it felt damn good. Mark shook his head and said;

"I love that laugh sis I really do."

"And I love you little brother." I told him and leaning over gave him a kiss on the cheek.

We arrived at Mom and Dad's ten minutes later to find them waiting on the porch for us. In the few seconds it took me to get out of the car, Mom, at just about a dead run, had already reached us and immediately through her arms up around my neck. I all but fell back into the car she had hugged me so hard, but I caught my balance and hugged her back just as tightly. I could feel my eyes filling up with tears and could already feel Mom's on my neck.

"Oh Megan honey," She said in my ear. "It's so good to have you home!"

I didn't answer instead just hugging her tighter. Seeing Dad approach I extricated myself from my mother's surprisingly strong grip, and as my father put his arms out to me, gratefully folded into him. I closed my eyes and felt the tears pouring down my cheeks. Of course it was good to be able to be here with Mark and Mom but in a way being held by my father was even better. Before I had gone into the clinic I hadn't spoken to my Dad in almost two years and the years before that weren't much better.

When Mark had brought me home from New York and took me to their house to stay a couple of days before checking me into the clinic, I had seen my father cry for the first time in my life. He had cried partly in joy for seeing me, because at that point they had truly believed I might be dead, but mostly because of how terrible I looked. During my six month stay Dad had come to see me almost every day and had attended counseling sessions with me to help work on our relationship. I was overcome with mixed emotions; sadness that it had gotten so bad in the first place, but also joy and appreciation that I had gotten another chance with the man who had taken me in and loved me as his own.

I pulled away and looking up at my father saw that he was fighting back tears himself. Giving him one of my huge crooked smiles, the kind of smile that until recently had been sadly absent in my life, I batted my eyelashes and sticking out my lower lip like I used to when I was little said;

"I missed you Daddy!"

My father laughed and hugging me again told me;

"It's good to have my little girl back." Laughing again he added; "Now let's go eat before your mother threatens us with staying here cooking."

I laughed and turned to look at Mom to see if she had heard it. She hadn't, she was over at the other end of the car hugging Mark, who had that comically awkward look on his face that he always had when someone was displaying emotion around him. I'm sure Mom was crying on his shoulder, and probably telling him thank you for the thousandth time in the last few months, which may have been a few less times than I had said it.
