Siblings with Benefits Ch. 30

"What!?!" Mark exclaimed. "What the fuck kind of question is that?"

"One I want you to answer Mark." Alex said quietly. "Once again, are you having sex with your hot sister over there Mark?"

"Fuck you Alex!" Mark snapped his eyes starting to bulge.

"Yeah whatever Mark, yes or no?"

Mark jumped to his feet startling me and pulling the cuffs from his fingers tossed them onto the table.

"I refuse to answer that! What the fuck is wrong with you Alex? How fucking dare you say that about us? I should..."

"Oh please." Alex said leaning back in his chair calmly. "Stop with the threats Mark I'm not a punk in the street you don't scare me. And spare me the righteous indignation just admit it."

"Bullshit!" Mark yelled. "I'm not saying shit about this you sick fuck!"

"Mark stop." I said softly.

It was over and the last thing we needed was Mark pissing Alex off we would have to see where he was going to go with this. Maybe Mark had been right earlier and Alex would just keep it too himself. Still the thought of him knowing was making me sick to my stomach what if he did tell my parents? All this flew through my mind in seconds and I forced myself to try to speak so Mark wouldn't.

"Just let it..."

"Don't say a fucking word!" Mark snapped at me so forcefully I froze. Mark had never spoken to me in that tone. Pointing at Alex he said; "Don't even dignify this piece of shit with an answer!"

"I have news for you Mark," Alex said his voice also rising. "You already answered me by not answering me!" Alex pointed at me.

"Look at her face Mark! Sis is scared shitless I caught you Mark, both of you. now cut the shit and watch your fucking mouth before I make sure everyone else knows too."

I felt tears rising behind my eyes and was ready to pretty much start begging but I caught Mark looking at me.

"Trust me." He whispered in latin.

"That Latin must come in handy when you talk dirty to each other." Alex laughed. "Sitting there in front of your parents whispering about all the dirty little things you did in their house."

"I'm warning you Alex." Mark said beginning to remove the straps from his chest. "You spread that bullshit I'll..."

"Do absolutely nothing." Alex told him. "You'll do nothing Mark because if you do there won't be a person in this state that won't know all about you and your slutty sister's little games. So you just back the fuck off." He looked coldly at Mark and added;

"So who do you think would hire an attorney who fucks his sister? Like bartending Mark? You'll be doing it forever." He then smiled. "Then again you and your sister are both pretty good looking maybe you can do incest porn make some money." He grunted.

"Hell wouldn't be the first time you got paid for sex and sis over there's done okay getting on her knees. Usually not for cash though."

"You mother fucker..." Mark said softly.

"No Mark, get it straight, you fuck family members not me."

"Please stop Mark," I whispered.

I could see Mark ready to explode and didn't want that kind of trouble. Trying to stay calm as Mark had said I still didn't give anything away as I simply said;

"He thinks he's got something he's not going to stop." I looked at Mark who looked like he was ready to snap. "Let it go little brother."

"Aww little brother." Alex laughed a surprisingly cheerful one. "That is too cute." He looked at me. "So do you whisper that in his ear when he fucks you? Do you say come to your big sister?"

"You're going to be sorry Alex you really are." Mark said softly.

"Oh knock it off," Alex said looking up at Mark who was glaring at him.

Alex seemed to be not only quite relaxed but very pleased with himself as he leaned back and looking over at me said;

"Hey look, I don't want to make trouble for you. But you know how I am I've been thinking the two of you were a little too close for awhile now but never thought you were this close."

He put his hands up as if saying oh well then continued;

"Then I hear sis in your room moaning like a $10 hooker and out she comes with her tits all but hanging out and looking like the cat that ate the canary." Alex nodded.

"So I was pretty sure and this proves it."

"It proves nothing." Mark began...

"Then why didn't you answer Mark? You didn't answer because you can't lie through that thing. Tell you what you should have at least tried. Anyway don't worry about it it's not like I am going to tell anyone. So calm down Mark," With that he grinned. "I would like to know some things though."

I looked at Mark who was watching Alex as if he were waiting for something.

"I mean is like the sex hotter because you're related? Do you guys really call each other brother and sister when you fuck?" He smiled and looked at Mark.

"So what's it like to watch your sister suck your cock Mark? Bet she's good at it; look at those lips. Never mind the experience she's got."

"Don't talk about my sister." Mark said quietly.

"And you know speaking of experience," Alex continued ignoring him and turning to me. "I bet you taught your little brother to do more than kiss. Did you teach him to kiss your other lips too sis.?"

I somehow managed to look at Alex and remain quiet. My eyes were tearing up and it was everything I could do not to start crying. Alex looked as if he were going to look away then slapped the table in front of him so hard I jumped.

"Holy shit!" he exclaimed. "I just realized something." He slapped his forehead. "Oh my God you were Mark's first weren't you?"

He started laughing and looked back at Mark who was now leaning against the chair he seemed to be calming down but still had that air of waiting for something.

"Your big sister took your virginity!" Alex said shaking his head as if it was the funniest thing he had ever heard. "Oh that is too much! So did you make the first move Mark? Maybe one night you guys are cuddled up and your hand brushes against her tits or her ass grinds into your cock or..." he trailed off as Mark slowly shook his head at him.

"Well you can tell me another time." Alex said. Shrugging he continued; "I just don't understand why you did or why you would still. I mean shit Mark you can have any girl you want." He waved his hand over at me. "And god knows any guy can have her."

At that I put my head down so Alex wouldn't see the tears flowing down my cheeks. This sounded like the Alex in my nightmare. Truth was he was right I had gone from not being able to have sex with men other than my brother at all to fucking anyone if I was high.

"Enough Alex." Mark said.

"Oh please Mark, it's not like it's not true and ... oh what are you doing?"

I looked up to see Mark had sat back down in the chair and was slipping the cuffs back onto his fingers.

"I told you that you were going to be sorry Alex." He said as he fumbled with the cuffs do to his fingers being restricted by the half cast.

"Oh please Mark why bother?"

Mark finished fumbling and looking at the machine stated his name and what color his eyes were. The needle remained steady until Mark said that Alex had brown eyes at which it jumped. Mark looked up at Alex and said;

"Shall we? What do you want to know?"

Alex sighed and laughed.

"Okay Mark, hell maybe now it's out in the open maybe you want to brag. Hmm" he looked over in my direction.

"So how's sis over there like it best? Doggy? She like to be on top of you?"

"I don't know how she likes it."

"What do you mean you..." Alex stopped as looking down he saw that the needles hadn't moved.

"My sister is a very attractive girl." Mark said. "I think she is one of the most beautiful women I have ever seen." As he added that Mark looked my way and gave me a soft smile.

"But," he continued looking back at Alex. "I have never thought about having sex with her."

Once again the needle stayed still and Alex slapped the table but this time he seemed upset.

"Bullshit! The two of you were fucking in my goddamn house! I heard you!"

"You heard wrong Alex." Mark said quietly. "We were playing around wrestling and I was tickling her. You're a sick bastard Alex."

"Fuck you Mark!" Alex snapped. "You're the sick prick here! Both of you are sick! A brother and sister fucking!"

The roles had reversed and now Alex was getting pissed while Mark not only sat there calmly, but began to smirk at Alex. Shaking his head Mark began to speak quietly;

"I have never had sex with Megan Alex."

I felt my heart leap as somehow the needle was not moving. Alex saw it as well and frowned as Mark kept talking;

"And before you ask anymore stupid questions let me try to set it all straight; I have never fucked my sister. I have never played with her tits, I have never fingered or licked her pussy." Mark paused as if thinking. "Megan has never jerked me off or given me a blow job and when we slept together we were never naked. Hell I have never even seen her naked."

On the last statement the needle rose and, mimicking Alex, Mark slapped his forehead with his good hand.

"Nope sorry Alex that's a lie; Megan and I shared a bathroom for three years so there were a couple of little shower mishaps. So I have seen her naked but I never thought about her once in that way."

As Mark was speaking the look on Alex's face went from anger to dismay to an almost comical look of surprise. Alex had leaned over to look at the graph so close his nose was almost touching it.

"Megan and I have never done anything inappropriate unless you count her showing me how to kiss and I was not turned on at all when she did I was embarrassed. And last but not least Alex? Megan and I were not and have never had sex in your house. Know why? Because we have never had sex." Mark looked over at me and speaking softly said;

"I love my sister more than anything but only as a sister."

I gave him a smile as relief flooded through me. I had no idea how the hell Mark had just pulled that off unless he... I realized suddenly that Mark had known all along he could do it! That was why he had told me this morning to not worry no matter what; he had been screwing up on purpose to make Alex think the machine worked on him. Mark had totally outplayed Alex. Speaking of Alex; he was now looking up at Mark and his face looked like all the color had drained from it.

"Anything else Alex?" Mark asked.

"I..." Alex stopped and for the first time since I had met him five years ago he seemed speechless. "I... where are we?"

"Were at Mitch's having a beer." Mark said in the same calm tone he had been speaking in.

The needle jumped.

"Oh my god." Alex whispered.

"Are you happy now Alex?" Mark asked him. "I am because now I know what you really think of me. And of course what you think about Megan. Really nice Alex," Mark shook his head. "Living proof that money can't buy class."

"Mark..." Alex stopped then out his hands up. "I am so sorry I mean I ... I really." He paused and turning to look at me quickly looked away.

"No Alex you're not sorry." Mark said calmly. "But you will be."

"Mark I..."

"What the fuck is wrong with you?!?"

I jumped and almost feel out of my chair as not only had Mark practically screamed that out but had leapt out of his chair fast enough to knock it over.

"Mark listen, it was a misunderstanding! I thought..."

"I don't give a fuck about what you thought!!" Mark yelled as he tore the wires off of himself. "You know what you son of a bitch? I don't give a rat's ass what you fucking think of me!"

"Listen Mark I...hey!" Alex shouted as Mark suddenly lunged across the table and grabbing Alex by the collar yanked him up out of his chair until their faces were inches apart.

"No you listen you motherfucker," Mark hissed into his face. "You sat there and called my sister a fucking whore more than once."

"Mark let it go!" I snapped.

I got out of the chair and reaching out grabbed his arm.

"I don't care what he said let's just..."

"Well I do!" Mark snapped and turned to face me.

I took an involuntary step backwards as when Mark had turned to face me his eyes were so dark they appeared black and his lip had curled up in a snarl.

"Stay out of this Megan!" He finished.

'All right Mark!" Alex said as, taking advantage of Mark's looking at me yanked himself backwards. There was tearing sound as his collar ripped. "I said I was..."

"And I said you're not!" Mark yelled. "Now get your ass over here!"

With that Mark swung his hand up and out catching the edge of the small table the polygraph was on and sending to flying end over end to crash a couple of feet to my right. I stood frozen as Mark stepped towards Alex who put his hands up as he stepped backwards.

"Jesus Christ!! Stop it Mark!!" I yelled at him.

"Mark get a grip on yourself." Alex said. He was trying to stay calm but as Mark approached him I could see he was nervous.

"Think your funny asshole?" Mark asked stopping in front of him and pointing his left hand at him. "Think calling my sister a slut if funny?"

"I..."

"Shut the fuck up!" Mark snarled. "You said enough. Let me tell you something you spoiled rotten little prick you don't know shit about my sister. But I'll tell you."

Mark pointed at me as he continued to speak. The muscles in his neck were bulging and his voice was strained as if he were so mad he couldn't speak.

"My sister told you all the bullshit I went through well let me tell you about her." Mark took a deep breath and lowered his hand. As he did Alex started to put his down. As soon as he did Mark's hand once again lashed out and caught him by the collar. Alex grabbed Mark's wrist but Mark pulled him up close enough that their faces were almost touching.

"My sister spent two years getting raped Alex. Raped. Nine years old getting a cock shoved up her fucking ass." Mark made a disgusted noise. "And you have the fucking nerve to say she's weak? That she wants to have the problems she has? To call her a fucking whore?"

"Mark let me go." Alex said trying to dislodge Mark's hand from his collar.

"You have no fucking idea what the two of us went through. No fucking idea. Spoiled rotten little prick. What was your problem growing up? Having to take the vette instead of the Mercedes? Fuck you poser!"

With that Mark shoved Alex away from him hard enough to send him staggering backwards.

"You've had it easy your whole life you little bitch. No idea what real life is. No idea what pain is." Mark smiled coldly. "But I'm going to show you Alex, oh yes I am."

"Are you threatening me?" Alex asked his eyes widening. "After everything I'm doing for you?" he looked at me as I stood near the shattered desk unsure of what to do.

"Megan tell your maniac brother to calm down. I... Oww!" Alex cried out in shock as Mark suddenly lashed out and slapped him in the face.

"Put your hands up asshole." Mark sneered. "My sister isn't going to save you."

"You... slapped me!" Alex exclaimed his hand going to his cheek where I could see the shape of my brother's fingers showing in the form of angry red welts.

"Like the bitch you are." Mark said. "Now fight!"

Mark's hand lashed out and caught Alex on the cheek again hard enough to rock him back on his feet.

"Mark!" I cried out and finally getting myself to move grabbed Mark by the arm again.

Mark spun around quickly and pushed me away from him. I staggered back and tripping over a piece of the desk fell back onto the floor landing hard on my ass. I stared up at Mark in shock unable to believe my brother had just shoved me down like that. Apparently neither could Mark as he stopped and stared at me.

"Megan I..." This time Mark's head was rocked back as Alex slapped him hard, not on his face, but the side of his head.

"You dirty prick!" Mark snapped. "I wasn't even looking!"

"Back off Mark." Alex told him. "You don't want to go to court tomorrow banged up and I swear to Christ if you swing at me again...."

Alex stopped as Mark lashed out again but this time Alex's hand came up and slapped his hand away. Alex swung another slap at Mark's head but he whipped his head to the side and again succeeded in slapping Alex hard, and this time in the mouth. I watched, still sitting on the floor, as Alex reached up and touched his mouth as if he were in shock. Pulling his fingers away from his mouth Alex looked at the blood on his fingers. Looking back up at Mark his lip curled up and his blue eyes blazing he took a step forward and took a swing at Mark.

Unlike before this was not a slap; Alex had thrown a fast right hook that missed as Mark simply whipped his head to the side. There was another loud crack as my brother brought his hand up and caught Alex with another open handed slap.

"Thought you were fast Alex." Mark said taunting him.

Alex swung again first with his right then his left. Mark blocked the left but when he put his left hand up to block the blow coming from that side Alex opened his hand and caught Mark's hand around the cast at his wrist. Before Mark could pull out of his grip Alex twisted hard to the left and Mark cried out in pain. As his still injured arm was pulled down and away forcing him to follow it. Alex swung with his left catching Mark in the side of the head. I heard a sickening thud as Alex's fist crashed into my brother's head. The force of the blow drove Mark down to one knee where he stayed cradling his left wrist in his right hand. From where I was sitting I could see Mark's eyes closed in pain.

"Stop it!!" I yelled jumping to my feet.

"I told you to back off Mark!"

With that Alex swung out and slapped Mark hard on the back of his head.

"Next time you listen and shut the fuck up!"

I started forward ready to get between Alex and Mark before Alex could hit him again. As I did Mark muttered something and Alex asked;

"Are you still talking Mark? I thought I told you too shut up!"

At that point I saw Mark's head cock and his eyes flew open.

"Oh no" I whispered as I stopped; frozen by the look of pure rage in my brother's face.

In an instant I knew Mark was going to lose it and why; Alex had almost word for word just shouted at my brother what Max had spent years telling him when he beat him 'are you still making noise' I tried to get my feet to move forward again but I was too late;

With an animal like snarl Mark launched himself up and swinging with his right hand caught Alex in the face with a backhanded slap that sounded like a gunshot when it connected. As Alex went staggering backwards Mark spun around, and bringing his left leg up to his hip, kicked out catching Alex in the stomach. The power of the kick drove Alex back until his back hit the door he started to fall forward but as soon as Mark's foot hit the floor he spun and kicked out once more. This time the blow caught Alex square in the chest and with enough force to drive him through the door which shattered behind him in shower of glass and splintering wood.

"Oh my fucking god Mark!" I yelled as I pushed past him to go check on Alex.

Asshole or not I found myself hoping to hell Mark didn't really hurt him. As I reached the doorway I saw Alex lying on his back in a pile of broken glass and what was left of the doorframe. I started to get down on my knees to see if he was okay when to my relief he sat up shaking his head.

"Alex are you alright?" I asked reaching out and putting my hand on his shoulder.

Alex's answer was to roll away from me and with surprising agility spring to his feet. I started to say something but saw Alex staring over my shoulder. Turning quickly I saw Mark step out into the hallway.

"Oh shit." I said softly.

Like Alex, Mark was staring past me. As he walked into the hallway Mark was un-wrapping the cast from his wrist; when he finished he tossed it aside and squeezed his hand into a fist tight enough to make the muscles in his forearms bulge. As Mark passed me I started to reach out to grab him but stopped as he turned to look at me.
