Oh, cum with me little brother, oh I want to feel it while I'm still ohhhh yeah."

Mark groaned, and after a couple of more hard pumps, his cock exploded sending a huge spurt of cum deep into his big sister's willing pussy. We both moaned as my pussy convulsed around my brother's spurting cock causing us both to enjoy our orgasms even more. After one more long shuddering moan I relaxed letting the last wave of pleasure flow through me. A moment later after one more spurt of cum into his sister's pussy Mark emitted that adorable little whimper that only I knew he made and started to pull out of me.

"Stay inside baby," I whispered as I straightened my legs out between his so that I was lying on my stomach. "Just let yourself go little brother, let me feel you."

Mark leaned over and placing his forearms on either side of me lied down on top of me.

"Easy baby." I said softly as I could feel his heart beating against my back, and hear his heavy breathing in my ear. "Just relax and stay close to me."

Mark slid his right arm under me, keeping his injured left hand off to the side. His hand cupped my left tit and held it as he relaxed more against my back he nuzzled into my hair and gently kissed the back of my neck.

"Oh you feel so good Mark."

"So do you sis."

I sighed enjoying the how good Mark felt on top of me then whispered;

"Mark what are we going to..."

"What we're going to do right now sis is get some rest." Mark said, and rolling off of me onto his side, put his arms out to me.

I gratefully rolled over and into his embrace. Normally I would always sleep with my back against Mark, however after that nightmare I needed to be even closer. I pressed my face into Mark's chest and wrapped my arms around his waist. Mark's strong arms pulled me even further into him and his right hand began to lightly caress my bare shoulder. Despite how upset I had been earlier, between the sex and how good my brother's arms felt around me, I found myself sighing contentedly into his chest. Mark's hand slid from my shoulder up into my long hair and rested on the back of my head holding me gently against him.

I was still lying awake several minutes later, and could tell by the sound of his breathing, that Mark was asleep. I rolled over onto my back keeping Mark's arm around my waist and sighed as I stared up at the ceiling. I should be fast asleep after that but my mind was racing. I was worried about Mark, despite how calm he was I had no idea how he thought he would be able to get through a lie detector test. The test was only part of what was on my mind. Mostly what had me unable to sleep was Alex. If he knew it had been my fault. Not only had I been careless coming out of Mark's room but had been so nervous that I had all but given us away. As I lied there with my eyes closed I found myself again replaying that morning and how stupid I had been.

*****

I stood there speechless as Alex was standing not much more than a foot in front of me smirking away. How long had he been standing there? I was painfully aware that even though I'd had my face in Mark's arm I had cum pretty hard and god only knew I came louder than most porn stars. As time seemed to stand still I also became aware of the fact that my robe was barely tied. Quite a bit of my chest was showing, and it wouldn't take much for my tit's to be exposed. I had been in the process of getting ready to pull it tight but now was afraid to draw attention to it.

Alex was looking into my eyes, but I had no doubt he would have noticed my chest all but hanging out. Alex hadn't said anything and his expression was unreadable. Desperately hoping my voice wouldn't tremble I forced a laugh and said;

"Sorry you kinda scared me."

"I can see that." Alex said softly, and then grinned a little. "You seem jumpy."

"Yeah a little." I gave another laugh that to me sounded way to forced, then shrugged and said;

"Well umm good morning."

Alex nodded and said;

"Yeah I'd say." Before I could respond the grin turned into a smirk and he added; "Sounded like a real good morning."

I felt my stomach begin to turn. Think Megan! My head started pounding and I quickly shoved my hands under my arms so Alex couldn't see the shaking. Okay I told myself, play dumb. Mark and I had had several close calls in the past and had always slipped through by relying on the fact that most people would never assume we were doing anything. Then again, Alex was not most people. Deciding to play along I narrowed my eyes and asked;

"Umm..." Shit! Don't stutter! I yelled at myself. "What do you mean?" Let him say it if he heard something.

Alex regarded me calmly, his piercing blue eyes locking into my bloodshot ones. I returned the stare. I had never lost a stare down in my life and could barely blink when necessary. Alex held my gaze and I could all but feel his mind turning. Alex relaxed a bit, and sliding his gaze from mine, shrugged and said;

"Well I heard Mark laughing in there. I haven't heard that since all this started so I figure it's a good morning."

I held back a sigh of relief and nodded.

"Yeah, he's feeling a lot better. We were talking and kidding around." I shrugged. "He seemed like his old self."

"Good. I was worried this morning." Alex replied then, locking his eyes into mine, once more continued; "See I was walking by and before the laughing I could have sworn I heard moaning." His expression didn't change as he spoke and I hoped to hell mine didn't either.

'That's why I was at the door; I was going to see if he was okay."

As I stared at him I swore I saw the corners of Alex's mouth twitch just a little, and my heart started pounding in my chest; he was toying with me. Gathering what was left of my nerves, I nodded and said;

"Yeah well he banged his arm and got it pretty good and..."

"Really?" Alex grunted and shook his head. "See I thought it sounded like you moaning."

"Me?"

"Unless Mark's voice is changing," Alex said grinning. "Sounded a little more like squealing actually."

As he finished Alex raised his eyebrows at me, all but saying "Your turn"

Before I could respond, Alex glanced down, then taking his hands, grabbed the front of his t-shirt and made as if he were pulling it together. Grasping his meaning I removed my hands from under my arms and grabbing the belt of the robe pulled it tighter and started to tie it. My hands were shaking.

"Sorry, couldn't help but notice you were hanging out a bit. " Alex said smirking. "Kind of funny, it looked like you were just putting it on when you came out of there."

The look on his face told me he knew exactly what he had heard. I felt a burning in my stomach yet, at the same time, my mind seemed to slow down as I searched for a response. Alex was good, but I had been lying about my brother and I for years, and since I had been going downhill had become damn good at lying in general. As soon as he stopped I rolled my eyes and let out a quick laugh. "Sorry," I giggled again as I closed my robe. "We were wrestling around in there and..."

"Wrestling?" Alex asked dubiously.

"Yeah," I forced a smile as I got into my story. "I got tired of him moping and said I was going to kick his ass. Next thing you know we were kind of rolling around and he was tickling me and I was..."

"Squealing?" Alex asked, the smirk still in place.

"Yeah I'm really ticklish." I continued ignoring the smirk. "So Mark was holding me down and I grabbed his bad wrist by accident..."

"Moaning." Alex nodded.

"So we stopped and while he was sitting there holding his arm I told him he was a wuss and that his big sister had kicked his ass."

"So he started laughing." Alex finished for me. "Sounds plausible I guess."

"What's that supposed to mean?" I asked. Seeing Alex seemed to think I was lying, which of course I was, it was time to try to go back to good old indignation.

"Doesn't mean anything." He answered shrugging. "So were you in there long?"

"A little bit why?"

"Just wondering. I mean it's not even six you usually sleep later than this."

"I haven't been sleeping and neither has Mark." I answered fighting to keep my voice even as I waited for Alex to show his hand and outright accuse us of something. "Honestly Alex after what you said last night about him needing to get his shit together I figured I would go in and if he was awake talk to him."

"So you went in to talk?" Alex asked. "Figured you'd keep him company?"

"That's what I said."

"Oh," Alex nodded. "So you always hang around your brother with nothing on under your robe?"

I hesitated as that had caught me off guard. This time when I spoke I could hear the tremble in my voice.

"I... he's my brother he doesn't look at me like that."

"But I'm here Megan." Alex pointed out then smiled. "And look what happened. You almost walked right into me with your tits hanging out."

"Well that's why I was leaving to go get dressed before..."

"So did they fall out while you were wrestling?" Alex's smile was getting broader.

"Well no I..."

"Are you wearing panties Megan?"

"What?!?" I asked indignantly "What the hell kind of question is that?"

"Well you're not wearing a bra so figured..." He winked. "Maybe nothing else."

"I wouldn't not wear panties around my brother!" I said. Before I went any further I knew I'd slipped.

"But no bra is okay?"

"I..." I was getting nervous now but couldn't hesitate so kept going. "I wasn't really thinking. I just wanted to check on him and..."

"And I went to bed so you could."

"I... what..." I was stuttering now and my stomach was turning so much I was getting nauseous.

"I've seen you Megan." Alex said calmly. "Every night I'm watching tv I see you come out and look to see if I'm up. Then you drift back in your room."

"I..."

"Or if you see me look you come out and sit and fidget for an hour." Alex continued in that same relaxed tone that was making me more and more nervous. "Funny you never wanted to check on Mark then." He put his hands out to me and finished;

"So last night I go to bed and come out here and sure enough you picked this morning to check", he emphasized the word. "On Mark, Just seems kind of odd. You know like coming out of his room with your tits all but falling out."

"We...we were fooling..."

"You were fooling around?" Alex asked. "Fooling around with your brother?" He laughed. "Damn Megan that's pretty..."

"I wasn't fooling around with my brother!!" I snapped loudly. Way to loudly. I tried to recover.

"I mean I was but I mean really fooling around not you know...I." I stopped and with a cold feeling realized I had all but given myself away.

Alex stared at me he eyes wide and I realized he really had only been fishing but now...

"What?"

"I... um." I shook my head. "Nothing I..."

"What were you going to say Megan? " Alex asked.

"I... well that you know we were only messing I mean play..." I stopped and swallowed hard. "Me and Mark were just talking that's all."

"Course you were." Alex said looking confused. "What the hell else would you be doing?"

"Um well nothing of course." I managed to get out as I was getting to the point I could feel my breathing pick up and my heart was pounding in my chest.

"No really Megan. "Alex prodded. "What else would you and Mark be doing?"

"Well, I mean you were kind of making it sound bad. I mean you said you heard," I hesitated "Moaning, and you were talking about my robe."

"Yeah so?" Alex asked.

"Well I thought maybe you thought that we..." I stopped horrified. I had done it again.

"Thought...?" Alex waited expectantly.

I didn't answer right away and Alex asked again. "Seriously Megan what did you think..."

"That we were fucking okay Alex?" I asked suddenly unable to hold back anymore. "That's what you were saying; that Mark and I were fucking!"

"Whoa hey. " Alex put his hands up to me in calming gesture. "Megan why the hell would you think..."

"Because it's what you're trying to say!" I snapped. "You... you keep asking what I was doing and the noises and ..."

"Christ Megan." Alex said shaking his head. "I..."

"You said it!!" I was raising my voice now and waving my hands as I yelled. The last three weeks and the fact that I had just about admitted there was something going on between my brother and I had caught up with me and I losing it. "I said fooling around and you said we were sick!!"

"Megan!" Alex said sharply. "Calm down I was only playing around. It was just a joke. You said fooling around and I..."

"I'm close to my brother and I worry about him is that okay Alex?!?" I demanded. "I needed to make sure he was okay and you're right I didn't want you to see me going in there in the middle of the night and I..."

"Why?" Alex asked. "Why would I care when you guys talk?

"I..." I stopped speaking and put my head down. I just kept making it worse. Unable to control myself I could feel tears start to flow down my cheeks.

Alex reached out and taking my chin gently in his hand raised my head back up.

"Megan what's wrong? Why would you think I would think that? You guys are kind of close but you always have been. I mean Mark's your brother. why the hell would I think that?"

"No reason." I whispered turning my head away from him.

"There has to be a reason Megan." Alex said. "People don't just think that kind of shit." He appeared to be struggling not to smile. "Unless of course something happened and..."

"I'm I... I just took you wrong that's all and..."

"No Megan, I'm not stupid. There's something there Megan you're a little too nervous."

"I..." I forced myself to look at Alex and my mind grasping at straws decided to try to justify myself. "My... my dad thought we... that Mark and I were to close."

"Doug?" Alex asked. "Doug thought you guys were..." he left it hanging.

I nodded and taking a deep breath explained to him how a few years ago Mark's nightmares wee so bad that the only way he could sleep is if I slept next to him. Of course I left out how close we would hold each other, but told him of the night at the hotel how dad had walked in and we were in the same bed and dad, who never trusted my brother, thought the worst. I told Alex how I had to beg my father not to throw my brother out and how afraid I had been for him. As I spoke I tried to read Alex's expression. He seemed to be genuinely listening but Alex possessed a hell of a poker face and his eyes were unreadable. When I got to the end I sighed and said;

"So when you were saying that I just..." I swallowed hard. "Over reacted and ..."

"Megan?" Alex asked.

"What?"

"You were way to nervous for it to just be that." He grunted. "Hell I didn't know that story I think your just a little to defensive there," he grinned. "Sis. But hey know what? If you guys want to keep it in the family I..."

"Don't say that!!" I practically screamed at him. "We were only talking!!!"

"Easy Megan!" Alex said looking alarmed. "I was only jok..."

"No you're not!!!" I yelled at him. "You think we are!! Were not!! I love my brother, he's all I have!! And I would never..." I let out a sob.

"Hey hey," Alex said looking more nervous by the minute now that I was losing it. "Megan calm down." as he spoke he reached for my arm.

"No I won't calm down!!" I cried out as I stepped back away from him. "I can't! Your right I'm nervous!! You know I got problems, I know you know because you call me names and make fun of me!!!"

Somewhere in the back of my head I was telling myself to stop, but it had all caught up with me and I couldn't help myself. Despite Alex's trying to shush me I kept yelling.

"I haven't had a drink or taken anything in weeks and my brother might lose everything!!!" I sobbed again. "And you, you come out with thinking I would do that with him!! I'm not a sick whore!!" I screamed at him.

Yes you are the voice in the back of my head said. Oh yes you are you nasty girl, fucking your brother and lying about it.

"Megan..."

"Yes I'm a drunk, yeah I do drugs and yeah I... I'm a fucking loser!" I was yelling louder and waving my arms wildly unable to stop. "But I'm trying Alex!! I'm trying to help Mark! I can't lose my brother!! I..."

I stopped as Alex caught my hands in his, and pulled me right up to him.

"Shhh." Alex whispered. "Please Megan slow down. I... I don't think that about you. You're a good kid you just need help." He let my left hand go and put his hand on my shoulder. "Now calm down okay? Please. I want Mark to be okay to and he will be. I'm... I'm sorry I got you going."

I started to take deep breaths and leaned into Alex putting my head on his chest as I tried to get myself under control. Whether I had convinced him or he just stopped because he felt bad I had no idea but I had at least gotten him to stop. Alex put his arm around my neck and we stayed standing there for a minute until I stood up and wiped my eyes with my left hand.

"I...I'm sorry Alex I..."

"No," Alex said. "I'm sorry Megan really." I felt a glimmer of hope as he looked like he meant it.

Alex was still holding my right hand and he gave it a squeeze. I hugged him pressing my tear streaked cheek against his. As I did he whispered in my ear:

"Look Mark will be okay and so will you. It will work out okay?"

"O-okay." I said pulling away from him and wiping at my eyes again.

Alex squeezed my hand once more and let it go. I looked up at him and he gave me a reassuring smile. As he stood there he wiped his hand across his face where my tears had left his cheek wet.. His hand trailed across his upper lip and he froze. I stared at him as he kept his hand under his nose and his eyes widened. I realized with a start that not fifteen minutes ago I'd had that hand buried in my pussy, playing with myself as Mark had fucked me. Alex still had his hand under his nose and as he saw me looking his lips curled up into a smile and he made a show of taking a deep breath. What the hell could I say? I was playing with myself... All thoughts stopped as deliberately slowly Alex put the tip of his finger in his mouth. He pulled it out and said;

"Well, this kind of..."

"What the fuck is going on out here?" Mark said from behind me.

I all but sobbed in relief as Mark stepped out of the room and came up next to me where he immediately put his arm around my shoulder.

"What's the matter Meg?"

I didn't answer instead I turned into Mark and putting my back to buried my head in my brothers chest and started crying. I knew this was the wrong thing to do, to get this close to Mark in front of Alex but I couldn't help it. Mark put his arm around me and I heard him say;

"What the hell did you say to her?"

"Nothing Mark," I heard Alex say. "She's just..." he sighed. "My fault, I was teasing her and said something stupid. I said I was sorry..."

"Sorry is what you will be." Mark said softly. "I've told you before Alex I don't give a fuck who you are no one talks down to my sister."

"Well well." Alex said. "You do seem more like yourself today don't you?"

Hearing Alex wasn't going to say anything I leaned back, and with an effort, removed myself from Mark, who was staring Alex in the eye as if daring him to say anything. I could tell in that look that he had been listening and knew what was going on, he was waiting to see if Alex would keep it up.

"I do feel better." Mark said. "Tell you what Alex instead of teasing my sister why don't you make yourself useful?"

"Oh?" Alex asked. "And how should I do that?"

Mark smirked at him;

"By getting on the phone with that sorry assed excuse of a lawyer you stuck me with and tell him to get over here so I can tell him how he's going to get me out of this."

To my relief Alex smiled broadly and reaching out slapped Mark hard on the shoulder.
