Siblings with benefits
Chapter 26 continuation 3

I pulled myself forward and rocked back one more time and this time when Mark was buried to the hilt I wiggled my ass against him letting him know I was ready. With no hesitation Mark pulled back and began fucking me with long deep strokes that caused me to let out a little yip into his hand each time he plowed into me. Mark wasn't slamming me as hard as he could because the two assholes that had come in were still talking, but he was using the entire length of his cock each time he pumped me and it felt incredible. I leaned forward a little and, turning my head, rested my cheek against the cool tile staring at the graffiti on the wall of the stall while my brother fucked me, I thought; Oh you nasty, nasty girl.

Mark let go of my hair and, leaning over me, reached underneath and, replaceing my clit with his fingers, began rubbing it hard and fast. As he did this Mark also began fucking me harder and even with his hand over my mouth I was starting to get loud. At that moment I heard the stall door open next to us and heard the guy say;

"Fuck this one's broken too!"

Mark should have slowed down at that point until he walked away, but instead started slamming me harder, making it more difficult for me to stay quiet. I knew he was doing it on purpose, so deciding to return the favor, I reached down underneath and the next time my brother drove himself into me caught his balls in my hand and rubbed them. Mark let out a surprised moan and suddenly there was a knock on the stall door.

"Hey pal, what are you doing? Sounds like you're stroking it in there. Christ man, I gotta go!"

Without missing a beat and his voice perfectly steady Mark snapped;

"Fuck off, I have stones, go replace another bathroom."

"Oh shit man," The guy said. "Sorry."

This time it would have been a laugh not a moan that would have escaped from me. Never in my life had I ever seen anyone think as quickly as Mark. I suppose that was why he was an exceptional attorney. An exceptional attorney with a magnificent cock that, as soon as we heard the bathroom door close, he began to use to full effect, rearing back and slamming the shit out of me! At this point I don't know why Mark was bothering to cover my mouth since the sound of our bodies slapping together as he pounded my hot little pussy was echoing throughout the bathroom. My brother's fingers were rubbing my clit harder and faster and, removing my hand from between my legs, I reached up and, grabbing my left nipple, started twisting the barbell back and forth.

I moaned into Mark's hand as my legs started to shake and I could feel the orgasm rushing through me. Behind me my brother was beginning to gasp with every stroke and I knew that any minute now he would be filling his big sister's pussy with his hot wet cum. The thought of how good that was going to feel sent me over the edge. I squealed into Mark's hand as I felt my pussy contract around his cock and waves of pleasure slammed through my body. My legs were shaking so badly that, as I continued to slam my hips back into his huge cock, Mark let go of my mouth and wrapped his hand around my waist to hold me up. I hadn't expected that and my next loud cry of ecstasy was released into the air where the echo caused it to sound even louder.

Mark let go of my clit and, grabbing my hips, gave me several savage pumps that were so hard I couldn't hold back and cried out loudly each time his massive cock rammed home in my hungry pussy. I realized from the sound of him moaning behind me that, that was exactly what Mark wanted and, on his next pump, I threw my head back and let out one of my trademark loud wails. That did the trick as this time, when my brother's cock drove into me, I felt a huge hot spurt of cum go deep into my pussy.

"Oh yeah baby!" I moaned. "Oh yeah just like that! Oh I want all of it! Give me all of your hot cum!"

Mark gave me several softer thrusts, each ending with another nice blast of cum. I pushed myself against him on the last pump and contracted my pussy around his cock, milking out the last drop and causing him to make that adorable little whimper that I knew always embarrassed him when he made it.

"Awwww baby." I whispered as he made the noise.

I was looking over my shoulder as I spoke and laughed softly as he gave me that shy little smile that only I could ever get from him. We both sighed as Mark slid his cock from my pussy. While Mark cleaned up as best he could, pulled his pants up and fixed them, I stood up pulled my dress back over my tits and waited a minute. Sure enough after a few seconds I could feel cum begin to drip down my thighs from my overflowing pussy.

"Hey Mark." I whispered.

As he looked over I lifted my skirt and showed him his cum dripping down my leg.

"Oh damn." He said.

"Lucky we'e out or I'd make you lick it off." I said winking.

I quickly wiped his cum off my leg and pulled my thong back into place over my still oozing slit. Then, as Mark grabbed his bag,I followed him out of the stall where we both stopped and stared at a man with two teenage boys standing there. I immediately put my head down to hide my grin. My brother, however, very causally, not only walked past them, but stopped and washed his hands while I stood there trying not to look up. As Mark finished he looked at the three of them and, after winking, took my hand and led me towards the door, as we were leaving I heard one of the boys say;

"Damn dad that woman was hot!"

I looked at Mark who gave me a huge smile and said;

"Damn I love Chicago!"

The rest of the night was nothing short of amazing. Dinner was wonderful; we took our time ordering everything from appetizers to desert as we caught up on everything that had been going on in our lives. As Mark had asked I avoided the trial, although part of me had thought about trying to press anyways, but seeing how relaxed and happy Mark seemed after our little bathroom romp, I avoided it. Mark did however mention that the phones at the firm had been ringing off the hook and people were lining up to bring their business to the lawyer who had defeated the legendary McAllister. I shook my head thinking, who would have thought two fucked up kids like us would be sitting across a table talking about how much money we were making. At that moment I felt one of those overwhelming waves of gratitude flow through me. Gratitude that I had overcome my past and was able to be with my brother and feel as if I were his equal rather than the burden I had been for years.

After that we just made small talk and, once again,I thought how much I loved having Mark come down here. As we talked Mark had reached out and taken my hand across the table and, as he gently ran his fingers across the back of my hand, I noticed that his eyes never left my face when I spoke. I couldn't help but smile as I thought about how into me my brother was tonight, as if there was no one else in the room but me. On that note, he had seemed more affectionate as well, holding my hand in the car as we drove and sitting with his arm around my shoulders while we waited a few minutes for our table. Not that I minded, but, much like that hug at the airport, it seemed as if there were something behind it, as if he were worried I was going somewhere. It reminded me of how close Mark had stayed to me when I had first come out of rehab, like he was afraid he was going to lose me. I didn't bring it up as I loved him being this close to me and also because I figured considering everything he had been through he just needed his sister more than usual.

As we ate desert I found myself thinking once again about how the word beautiful, really did fit my little brother. On our way to the restaurant Mark had convinced me to stop at my place for a few minutes so he could shave and put on a decent shirt. I didn't argue because I knew that although Mark favored the scruffy look he knew his big sister preferred him clean shaven, so of course that's exactly what I got. Even though Mark's features had hardened a bit over the years, they were still flawless and very much on the pretty side. Mark's thick black hair was slicked back, also my favorite look, and of course there were my brother's eyes. To this day I have still never seen a pair like them; greenish gold with flecks of brown along the edges. Mark's eyes tended to drift more towards one color depending on his mood and right now were green more than anything else, which was the shade I loved best. Right now those gorgeous eyes were staring deep into my own oddly colored, nearly transparent blue eyes and I found myself thinking that Mark did seem a little more into me than usual.

After dinner we went to a private dance club that I had bought a membership to last year with nights just like this one in mind and the fantastic evening continued. Both Mark and I were sexy, knew how to dance and, absolutely loved showing off. Again it was nothing short of a turn on to be bumping and grinding all over this gorgeous man in front of a room full of people who were checking us out, and secretly knowing that we were brother and sister. I have to say that, since I have been sober, I have no self-esteem issues and would even consider myself a bit vain. Having said that, I never felt sexier than when I was with Mark. My brother made me feel beautiful and desired, like he had my entire life, even at times that I was as far from that as possible. After several dances Mark had gone to our table and removed his shirt leaving himself in just the tank top, and when he came back out on the floor Nine Inch Nails Fuck you like an animal came on. Mark came up behind me and, wrapping his arms around my waist, began grinding his cock into my ass, as I leaned back swaying against him.

As the song went on Mark's hands left my waist and began to slide up and down my body. I let out a soft moan as my brother's hands went down my thighs and on the way up he rubbed across the front of my tight dress hard enough to rub my pussy through the thin material, making my clit tingle. Mark's hands went up my sides then crossing his arms on my stomach he reached up and placed his hands over my tits. As we turned I saw we were facing two women who were dancing sensuously together and knew Mark had done this on purpose. Sure enough I saw one of the women, a tall blond, look over then whisper to her brunette partner, who also turned. They had been dancing in the corner and at the moment there was no one between them and Mark and me.

"Go ahead little brother." I whispered and reaching up and back wrapped my arms around his neck.

Mark grabbed the top of my dress and quickly pulled it down, flashing the two women my tits. Mark's hands left the dress and, lifting my tits up to better display them, gave my nipples a playful pinch. I moaned and as I did I, saw the blond slide her hand up the brunettes skirt from behind. Mark's hands left my tits and, dropping down, lifted the front of my dress up with one hand while pulling my thong up and to the side flashing my smooth pink pussy. Letting my hand drop from Mark's neck I reached down and slipped my finger through my wet pussy. The brunette returned the favor flipping her skirt up and showing us her pierced clit as well as the fact she was wearing nothing underneath her dress.

The song ended and, as I pulled my dress back up over my tits, Mark went to the bar to get me a Pepsi. Even after five years it still seemed funny to be in a place like this and only drink soda, but at this point there wasn't enough money in the world that could make me take a drink. I watched smiling as Mark got the soda, then stayed at the bar and did two shots. Ever since I had been sober Mark had made it a point never to drink right in front of me. I wouldn't care if he did, it's not like he had a problem, but I have to say I always deeply appreciated that he took it that seriously and was always concerned for me. While Mark was at the bar for a couple of minutes the blonde came over and, after introducing herself as Kara, wanted to know if Mark and I wanted to switch partners for a few dances. Kara herself was completely into women and said she would love to dance with me. Her girl friend Lexi however was bi and, according to Kara had been getting wet just looking at Mark and was dying to have him play with her the way he had been playing with me.

I thought about it for a minute. When Mark and I were younger we would have others whenever we wanted, then come back to each other. In our twenties Mark was doing anything female that moved, unless I was well around. As for me with the exception of an occasional woman and Tommy, I don't want to really to think about what my sex life had consisted of back then. Since I had gotten my shit together, Mark and I had made the rule that when we spent time together; no others were to be involved. If I was coming up for two weeks he had no pets, and no one nighters, even if I was staying with the folks. The same went down here for me. So as I looked at Kara I didn't really see a problem; they weren't asking for us to go home with them just do a little heavy petting on the dance floor.

I told her I would check with Mark. Kara walked back over to Lexi and I found myself staring at her ass and felt my pussy getting worked up as I envisioned my brother watching me play with Kara's tits for him, hell maybe I'd even suck on them. I also found myself picturing Mark getting Lexi all worked up with his cock and fondling her more than ample tits. Oh yeah, I thought we'd get all hot and bothered watching each other play then go back to my place and fuck the shit out of each other.

Mark came back from the bar and, after he handed me my soda, I told him what Kara had wanted. I smiled, expecting him to jump at it, but to my surprise he shook his head. I stared at him and said;

"Come on, it'll be hot! Look at them."

"It's our time Meg, remember." Mark said quietly.

"Hey Mark," I began. "Look we're not going to go back and fuck them, we're just going to play for a few dances." I smiled at him and, kissing him, said;

"C'mon little brother, you don't want to watch your nasty big sister, get her tits sucked by that hot blond or," I winked at him. "You don't want to reach into that skirt and maybe get a little feel?"

"No Meg I really don't."

"Hey Mark I just want to..." I stopped as he looked at me and shook his head.

"When I'm here I'm with you Megan, we hardly ever get to spend any time together and I'm not going to share you!"

"We were only going to dance Mark, just for fun I..."

"Can't you just be with me Megan?" Mark asked with a hint of exasperation in his voice. He stopped and shaking his head added; "Please?"

I looked at my brother and saw that he really was getting upset, not angry but upset. He had that flustered look that he got when he didn't know how to react to things, which usually meant he was either sad or hurt over something. The girls immediately forgotten I stepped up to Mark and gently touching his cheek said softly;

"Hey it's okay baby, you don't want to, we won't. Please don't get upset with me."

"I..." Mark shook his head and, putting his arm around me, whispered in my ear;

"I just miss you sis, that's all, I just want to be with you."

I could hear the emotion in his voice and, hugging him, said;

"And you will be little brother, all weekend. Tell you what, why don't we go back to my place and you can let your big sister show you how much she missed you."

Mark nodded and, holding hands, we made our way toward the elevators, as we passed Kara and Lexi I pointed at my watch and shrugged. Kara looked disappointed but nodded and winked at me I winked back fully planning on coming back the next week and seeking her out. The club had several levels with the wilder ones at the top, when we got off the elevator on the first floor it was in front of a place that was more like a bar with a dance floor and, as I started to walk by, Mark stopped and asked if we could go in for a few minutes. I shrugged and said okay. When we entered there was a ballad playing and Mark led me directly to the dance floor, turned to me, took me into his arms and began to slow dance with me.

I wasn't sure what was going on but it's not like dancing with Mark was a terrible thing so I leaned in and wrapped my arms around his shoulders as he held me around my waist. We swayed slowly to the music and, as Mark pulled me tighter to him, I once again felt that tension in him. I thought, after we went home and played some, when I had him nice and relaxed I would ask him about it. For now however I sighed contentedly and let myself fold into my brother's strong arms. When I did that I felt Mark relax as well and hold me closer as if my letting myself go was what he had been looking for. Mark pulled me even closer and, as we continued to dance, nuzzled his face into my hair and gently kissed my neck.

"Oh that's nice, little brother." I told him softly.

The song ended and another ballad came on so we stayed out there and I have to say I didn't mind one bit. At one point I leaned back so I could look into Mark's beautiful eyes and found him looking at me. Our eyes met and, as they did, Mark slowly leaned into me, his lips parted, I turned my head and, closing my eyes, parted my lips and waited. A moment later Mark kissed me, it was very different from how we had been kissing all night; it was soft, sweet and amazing. I moaned softly as his lips slid back and forth against mine and was disappointed when Mark stopped. That disappointment was short lived however as, gently placing his hand on the back of my head, Mark pushed my head down onto his shoulder and he held me even tighter as we danced.

As I sighed again I thought that this really was the best thing about Mark and me; as nasty and hardcore as we could be, as rough and hot as the sex was, we could have moments like this where we were soft and sweet and loving. It reminded me of when we were younger and living at the folks, those wild nights where we would tear into each other followed by those sweet playful mornings. The song ended and this time I pulled back and said;

"You ready to go back to my place, and be good to me little brother?"

"Oh yeah," Mark said softly. "That's exactly what I want."

We arrived at my condo a half hour later, and even the ride home was nice. Mark drove and I was sitting right at his hip and his arm was around me as if we were teenagers. At a red light Mark had turned his head down to me and engaged me in such a long kiss that we only stopped when someone behind us beeped for us to move. As soon as we entered my place I took Mark by the hand and led him into my bedroom. Although Mark had been in here many times it still thrilled me to no end to have my brother in my bed. It had taken me until I was thirty two years old to get my own place and I never took it for granted.

Unlike Mark I had no desire to turn my bedroom into a dungeon, but I did have a huge four poster bed that my brother and I had each been tied to on more than one occasion. While Mark went into the bathroom I lit several candles and pulled down the red top sheet to expose the brand new black satin sheets I had bought as soon as I knew he was coming down. I pulled the dress over my head and, after tossing it aside, turned to look at myself in the full-length mirror on the closet door. I have to say I thought my brother would be happy with seeing me topless in just my thong and the laced up heels that I had bought to wear just for him tonight. As I looked at my reflection I waggled my tongue out and, playfully grabbing my tits, whispered;

"Like what you see little brother?"

I turned as Mark came out of the bathroom and felt my pussy begin to heat up even more, as this nasty girl certainly liked what she saw. My brother had stripped down to just a pair of tight black boxer briefs and my god did he look good! As he slowly, and I'm sure deliberately slowly, approached me, I took in every inch of my beautiful little brother's amazing body. From his wide shoulders, muscular chest, and perfect six pack stomach, right down to his thick powerful thighs and of course that huge bulging cock. I felt my breathing pick up in anticipation and I looked up to see Mark's eyes lingering on my long well shaped legs and knew that every inch of that bulge was for his hot big sister, and trust me, this nasty girl was going to make good use of it, all night, hell all weekend long.
