"It's all me Mark!! If I didn't steal from you, you would have never found Max!! And now it's even worse! Alex caught us because I went into your room and then acted like an idiot when he caught me!!" I let out a series of sobs that were so hard they hurt my chest before continuing; "And I'm scared for you Mark! Oh little brother what if they don't believe you? And then ohhh the dream I just had! I...ohhhh."

I moaned into Mark's neck and just let loose with more gut wrenching sobs. Mark remained silent just holding me and gently rubbing my back. After several minutes the sobs lessened and I started getting some control back. When I stopped and was just lying limply in his arms. Mark asked;

"Do you want to tell me about the dream sis? Maybe it'll help?"

Taking a deep breath, I haltingly described the dream to him. When I got to the end about Frank I broke down again, and I felt Mark tense up. Ever since my brother had known what I had gone through any mention of Frank would get him angry. Before I had found out that Frank had died in prison Mark had always said that the day they let him out he would kill him. I used to think it was just something said in anger, but seeing what Mark had to Max made me thankful Frank had passed away, Mark hadn't been kidding. When I had finished Mark held me away from him so he could look at me and said;

"It's just a dream Meg, I mean Alex would never act like that he would never hurt you."

"It's the things he was saying Mark." I said sadly. "It...It's how he really feels about me! He thinks I'm just a drugged out whore and..." I sobbed again. "He...he's right Mark I've done it! I've fucked guys for it I... I just" I put my head down. "Needed it so bad and didn't have money and..."

"Enough sis." Mark said softly. "You'll get better..."

"And look at me now Mark! I'm a fucking mess! You...you need me and here I am balling like a fucking baby and you're holding me! I'm supposed to be helping you and..." I put my head down. "You don't need me Mark I'm only making..."

"Hey you listen to me Megan." Mark said grabbing my shoulder with his good hand. "First off, Alex has made some cracks before, but he comes from money Megan, he doesn't have a fucking clue where we come from or what we've been through so ignore him."

"He's still right." I said softly. "And Max..."

Mark stopped me with his finger to my lips. Then, taking a deep breath and looking me in the eyes started to speak;

"Max was fate sis. I was meant to find him and have my revenge Megan and, I'm going to complete that revenge by walking away scot free, and having everything I've always wanted while he walks with a fucking cane the rest of his life. And my sister?"

Mark gave me a smile.

"That future you keep saying I'll have." He took my chin and tilted my face up to his. "I would have never had the chance without you Megan. You saved me when I was younger sis. You really did. They were going to dope me up and put me in a training school and Doug and Denise wouldn't have gotten through to me. You've always been there."

At this point Mark drew me into his embrace again and began talking softly in my ear.

"I do need you Megan, and you have been here sis. You talked me down at my place and I know you were scared as hell and you did it anyway. You lied to the cops Meg, your story gave me a chance. Hell Alex even told me he wasn't going to help until he saw how upset you were and told him all the things Max did to me. I'd be in jail waiting for the hearing with a public defender if it wasn't for you sis." He squeezed me tighter and added; "Or still in the looney bin like our father."

I started to shake my head into his neck. I had done those things but it should have never come down to it. I was going to say that when Mark sighed and said;

"And most importantly." Mark paused and kissed my tear streaked cheek. "You gave me exactly what I needed a few nights ago sis." He kissed my cheek again. "You."

"Me?" I asked lifting my head to look at him.

"Yes sis you. I needed to be with you Megan. I needed to feel your body and how much you care and to have you hold me." He swallowed hard and I could see the emotions finally catching up with him. "I...I was going to give up Megan I really was but you felt so good" He gave me that little smile that I always loved and kept going;

"We felt so good together Megan it's like I always said were two halves of a broken whole. And if I quit I would never feel you again. And then what would happen to you?"

"You shouldn't be worried about me Mark." I said quietly. "That's the problem you need me and I'm being needy and..."

"We need each other Meg." Mark said. "Sometimes you put me together, sometimes I put you together. But sis, trust me when I tell you, that the last couple of weeks you have given me everything I needed. No?"

I looked at him, speechless that my brother could still love and need me after everything I had put him through. As Mark looked at me smiling softly I smiled back a little which caused his to widen. In the last week Mark had healed quite a bit, his left eye looked normal and almost all of the bruising and swelling was gone from his face. Even his hand was doing much better, now only in a thin half cast held on by ace bandages. I felt the tears welling up again but this time it was a different emotion, not fear or self loathing but affection for my brother, who was truly everything to me. Not trusting my voice I whispered;

"I do need you my beautiful brother."

Mark leaned over, and when our faces were inches apart, whispered;

"Then let your little brother give you what you need."

Before I could respond, Mark's lips met mine in a gentle kiss that caused me to whimper in my throat. Oh how good that felt! I eagerly returned the kiss and moaned again as, reaching behind my head; Mark slid his hand up through my hair. I closed my eyes as I opened my mouth and allowed my brother's tongue to slide in and caress mine. I had just started to wrap my arms around his shoulders when I remembered where we were, and what was going on. I put my hands flat against Mark's bare chest and pushed him away.

"Mark we can't!" I told him. "Alex could be out there right now." I added in a whisper

"Oh for Christ's sake sis," Mark said rolling his eyes. "He's not. I'm telling you don't worry about it."

"But..."

"Look Meg, I'm telling you he doesn't know and if he does then why stop now?" Mark shrugged. "Hell I've been slipping in here almost every night since you think he caught us."

"And I keep telling you not to!" I pointed out. The last two nights I had refused sex, not wanting to take any chances. Mark had gone along with it, content to simply lie there with his arms around me. Seeing Mark had snuck in and simply slipped into bed next to me told me he would have been willing to do the same tonight as well. After my nightmare however, Mark knew damn well what I needed and, was unselfishly willing to take one for the team and fuck his big sister back to sleep. It's not that I didn't need exactly that, but...

"Mark," I sighed. "If he doesn't already know he will. I'm telling you he's going to ask something at the test."

As I spoke, Mark had unwrapped the ace bandage that held the cast, and was now gingerly sliding it off. Underneath his wrist was heavily taped, but he was moving his fingers fairly easily. All the better to touch his sister I thought.

"And I'm telling you to trust me sis." Mark said, and taking my face in his hands, leaned close to me, and whispered; "Please just trust me, there's a reason I agreed to this test and that's all I can say."

"Mark I... hmmm"

Mark had leaned back in and kissed me once more. I tried to slide back, but his hand had moved to the back of my neck, holding my lips to his. As much as I knew we shouldn't, I felt my body beginning to respond. I could never resist my brother when I was in a good frame never mind when I needed him this badly. I once again opened my mouth, letting Mark's tongue slip in, and with a sigh of surrender, I wrapped my arms around his neck. Mark's tongue played across mine then breaking the kiss he smiled and said;

"There you go sis, you just let me make it all better."

"Ohhh that's nice." I said softly as Mark bent his head, and nuzzling into my hair began to gently suck on the soft flesh of my neck.

As Mark's lips and tongue lightly played across my neck I felt his hands drop down and tug on the bottom of the t-shirt I was wearing. Taking his hint I raised my arms up over my head and let Mark slip the shirt off of me. I instantly put my arms around him, hugging him tightly and loving the way my hard nipples felt as they pressed into his chest. Tossing the shirt aside Mark's lips went back to my neck and I groaned as, starting at my hips, his hands slid slowly up my sides to cup my tits. I leaned back onto my knees putting some space between us and Mark started fondling my tits, gently teasing my nipples with his fingertips. I reached out and returned the favor; lightly running my finger nails around Mark's nipples before slowly running them down his well muscled chest and his flat hard stomach.

My hands continued to slide down into the waistband of the black boxers he was wearing. We both moaned as, just as Mark bent his head to tongue my nipple, my right hand wrapped around his long thick cock, as my left cupped his balls. I started slowly stroking his cock as my brother's soft tongue teased across my right nipple before switching to the left. My breathing picked up as I could feel Mark's cock growing in my hand until it was hard, throbbing, and more than eager for his big sister. I pulled my left hand from his shorts and pushed against his shoulder, telling him to lie back, as I so wanted to suck on that huge cock. Mark grabbed my hand, and bringing his face up from my tit, kissed me and whispered;

"Just let me be good to you sis."

"But I..."

I started to tell him that I wanted to taste him, but was silenced by his lips over mine. As he kissed me Mark placed his hand on my shoulder and gently pushed me onto my back. Mark followed me down to the bed, his lips never leaving mine as he gently eased me down into the pillows. Breaking the kiss, Mark sat up and, grabbing the sheet, tossed it off of me. The t-shirt had been long and I wasn't wearing any panties. As soon as the sheet was gone I slowly opened my legs and smiled at the look of absolute lust in my brother's eyes as he stared at his big sisters smooth pink pussy. As Mark's eyes left my pussy to wander up my body I placed my arms over my head and stretched, arching my back off the bed, and pushing my small but well shaped tit's up to a sexier angle for him.

As my brother's gaze devoured my body, I was amazed that, even after fucking for close to four years, Mark still found me this attractive. I knew damn well that he had been with hotter women than me, but I had no doubt that his big sister's body was his favorite. Reaching down Mark placed his hand on my knee and gently ran his hand up the inside of my thigh. As his hand reached the top I lifted my hips in anticipation of his fingers finding my pussy. Instead Mark teasingly grazed the side of his hand across my clit then went higher caressing my stomach.

"Awww." I whispered. "Please little brother I... hey that tic..."

I broke out into a giggle as Mark's fingers tickled my stomach. Mark's smiled down at me and said;

"I love that laugh sis."

"And I love that smile little brother." I told him. Then as his hand started trailing up towards my tits I asked; "What else do you love?"

"I love these hot little tits of yours" Mark answered as his fingers teased across my right nipple.

I moaned as, switching his fingers to my left tit, Mark bent over and started sucking on the right one. Mark's hand once again left my tit and started sliding back down my stomach towards my now dripping pussy. I whimpered, and lifted my hips as his hand stopped inches from my pussy. Sitting back up Mark looked down at his hand as he slowly slid it down between my legs and whispered;

"Goddamn do you look hot sis."

The way he said it coupled with that look of desire on his face sent a warm feeling flowing through more than just my pussy. No man had ever made me feel as sexy as my brother did and I loved it.

"Ohhh yes," I sighed as Mark slid his fingers inside of my hot wet pussy. "Ohh that is so nice little brother."

I let out a soft whimper, as while pumping his fingers in and out, Mark's thumb found my swollen clit and began tracing slow circles around it. As I started gently working my hips up and down into Mark's fingers he lowered his head back down and once again started sucking on my right nipple. Mark was kneeling next to me and as he continued to work my body with his tongue and fingers I reached down and grabbing his hard cock gave it a squeeze that caused him to groan into my tit.

"Bring it up here." I told him.

Not having to be told twice, Mark slid himself over so that his knees were near my head, then turning to the side, immediately went back to sucking on my nipple.

"Oh look at that." I whispered as turning my head I was confronted with his dripping cock only inches from my face.

Reaching up I wrapped my arm around Mark's waist and pulling him closer guided his cock into my open mouth.

"Oh damn." Mark moaned around my tit as I took his cock down about half way and began to slowly suck it in and out of my mouth.

Removing my arm from around his waist, I slid my hand up between his legs and started to rub his balls, while taking his cock as far down as I could. I stopped sucking and moaned out around his cock:

"Hmm-mm"

Taking his cue, Mark started rocking his hips, pushing his cock all the way in, slowly fucking my mouth. I moaned as much from the pleasure of having my throat full of my brother's hard flesh, as from his thumb speeding up on my clit. I started thrusting my hips up harder and faster into Mark's fingers as his thumb picked up speed on my clit. I reached over with my free hand and started playing with my left nipple, twisting it roughly between my fingers.

Mark began sucking harder on my nipple and, sliding his injured hand up, grabbed my tit and started squeezing it as he sucked. I whimpered around his cock as I felt my body nearing its climax. I straightened my long legs pinning Mark's hand between my thighs and, arching my back, desperately wiggled my hips into my brother's plunging fingers. Sensing I wanted to cum quickly Mark started thrusting his cock into my mouth faster and harder knowing damn well I loved it when he fucked my face. As he buried his dripping prick deep into my eager mouth Mark caught my nipple between his teeth and bit down.

As soon as I had felt his teeth, I had given my other nipple a hard pinch, and the sensation of pain flowing through both my nipples was more than enough to send me over the edge. I squealed around Mark's cock and started bucking my hips wildly into his plunging fingers as the orgasm crashed through me. Mark had resumed gently sucking on my nipple, and his thumb was still rubbing my clit. I let out another long squeal, that had my throat not been stuffed with my brother's cock, would have been loud enough to wake the neighbors never mind Alex. As I moaned and thrashed on the bed, Mark held his cock still in my mouth, effectively gagging me with it.

Although he was still, I could feel his thigh trembling against my shoulder, and knew that he wanted nothing more to start fucking my face and cum himself. I released another whine of pleasure as I felt my pussy gush around Mark's fingers, and the last wave of the orgasm flowed through me. I slumped back into the bed and opened my legs allowing Mark to remove his hand from between them. Mark started to sit back and slide his cock from my mouth but stopped as I grabbed the base of his cock with my right hand. I turned onto my side and, now able to move my head, started to rapidly bob up and down on his cock while jerking him off into my mouth.

"Oh damn that feels good sis." Mark breathed out.

I started taking him deeper and deeper, sucking so hard my lips were smacking when I let his cock pop out of my mouth before slurping it back in. Mark started breathing heavier and his hips began to rock in time with my sucking. As I continued to blow him part of me wanted to stop as, what I really needed, was to feel my brother's huge dick inside of my now sopping wet pussy. On the other hand Mark was really enjoying his big sister's mouth and if that's where he wanted to cum that was fine with me. As if reading my mind Mark reached down and putting his hand on my head said;

"Easy Meg, you know I want to fuck you."

"Mmm" I moaned, as one more time I took his cock all the way down to the base of his shaft, before slowly sliding it back out. "Oh that sounds sooo good little brother."

Mark got up, and walking around to the foot of the bed, started to crawl up between my legs. I put my foot on his chest stopping him and with a smile said;

"Oh no little brother, not like that, you know how I need it tonight."

With that I rolled over onto my knees, and putting my face down into the pillow, raised my ass in the air and playfully wiggled it at him.

"Damn sis," Mark said as he got up onto the bed behind me started fondling my ass. "You have got the hottest ass I have ever seen."

"Then go ahead and take it little brother." I told him. "Go ahead and take your sister nice and hard, show me how much you want me."

I turned my head back into the pillow just in time for it to muffle the loud yelp I let out, as grabbing my hips; Mark drove the full length of his huge cock into my incredibly wet pussy. Mark left his cock buried deep inside of me for a minute and groaned as I clenched my pussy around it. After a few seconds Mark slowly slid it out until just the tip was inside then, with another hard thrust, slammed it back inside again. I yelped once more then began moaning continuously as Mark pulled out and started to fuck me hard and fast. Oh yes! I thought to myself this was exactly how I needed it right now, nothing fancy just a good hard fucking.

Mark squeezed my hips harder and started plunging his cock into my needy little pussy even faster. I recalled the nightmare, and once again thought of how my brother was the only man who I could let take me like this without any fear at all. That was one of the many reasons I had seduced him in the first place; to be able to fuck like this and never worry about getting hurt. As Mark continued to pound my pussy I reached down between my legs and started rapidly stroking my clit. I had worked Mark up quite a bit with my mouth, and after only a couple of minutes I could hear his breathing getting heavier, and could tell by how hard he was thrusting into me that he was already getting close. I added my other hand to my nipple and turning my head moaned out;

"Oh...Oh please just a little more Mark!" I let out a whimper as Mark slammed himself even deeper into me. "Oh please little brother let your sister cum on that beautiful cock!"

Mark groaned but slowed up a little. I sped my fingers up on my clit and, twisting my nipple harder, started to thrust back into Mark driving him even deeper into my hot little box. Mark let out a gasp and began fucking me harder again.

"Ohhh little brother, oh just a little more baby! I... Oh fuck yeah!!"

I cried out loudly unable to help myself as, in an effort to get me to cum, Mark had reached down and shoved a finger into my extremely tight ass. I buried my face into the pillow and cried out again as Mark's finger, plunging in and out of the spot that no other man was allowed near, caused me go off like a rocket. Squealing into the pillow I thrust my hips hard against Mark's hard cock as the orgasm crashed through my body. Each time Mark's cock slammed into me he let out a gasp and turning to look over my shoulder I moaned out;
