Siblings with benefits

At that moment I felt the orgasm begin to take me. My thighs were trembling around my brother and my hips were driving against his as hard as they could. I was right on the edge and could tell Mark was as well. At the last second as hard as I could I pushed my heels into his sides and turned my ankles twisting the heels into his sides.

Mark let out the loudest cry I had ever heard come out of him, and with one final thrust his cock twitched inside of me filling me with squirt after squirt of his hot cum. At the first squirt of cum I went off like a rocket. Wave after wave crashed through my body and the screams that were being released into my brother's hand were far from fake at this point. I wasn't the only one cumming that hard; my brother was still shooting off inside of me there was so much cum being emptied into me that I could feel it spilling out of my pussy and down my thighs. Mark fell off of me to the side onto his back, panting like he had just run a marathon. I was also lying there sucking wind; it had not been easy to breath with Mark's hand over my mouth. After gasping for a couple of minutes I turned my head towards him and asked;

"What the hell was that?"

Turning his head to look at me, Mark smiled a little sheepishly as if embarrassed and answered;

"I don't know I just always wanted to you know..." He shrugged. "Take you. I mean really take you and I figured nobody would hear us" He looked at me and frowned.

"I... was it okay? I mean I wasn't even thinking about..." He stopped and looked upset. "Damn Sis I never thought about before are you..."

I laughed at him.

"Little brother I have never cum that hard in my fucking life! I don't know where it came from but it was like I'd been waiting for it."

"You know," Mark said seriously. "I don't either, but it's like you said; it was like I was meant to, it just came easy."

I shrugged.

"Don't worry about it then. I mean it wasn't just me I..." I stared down at his side. "Damn Mark your bleeding."

Mark looked down at the small trickle of blood where my boot had poked a hole into his skin. He looked back at me and smiled.

"Hey they say it's a fine line between pleasure and pain guess we just crossed it."

I laughed again.

"That's okay it's not like it's the only line we've crossed."

We laid there on our backs still dressed from the waist down. It's what saved us from a lot of trouble. I was just sitting up planning on stripping my skirt off and lying back down for a nap, when there was a knock at the door.

"Hey guys." Dad called from the other side.

"Hold on." I responded.

I pointed at Mark and to the bathroom. As Mark zipped up and headed over I grabbed my sweater from the floor and had just gone to put it over my head when there was a click and the door started to swing in. "Megan did you..." Dad started as he came in.

"Hey guys" Dads voice came from the other side of the door as it swung in. Fuck! Mark wasn't out of the room yet and here I was topless! I dropped the sweater and crossed my arms over my chest yelling:

"Dad don't come in I'm..."

Dad entered and froze looking at me.

"Oh Jesus..." He said and turning his back to me shut the door.

Mark had just reached the bathroom, but thinking quickly immediately turned around as if he was coming out saying;

"Hey Meg, you okay out here?"

"I don't have a damn shirt on!" I snapped, desperation making me sound angry. "I told you not to come out until I said so!"

"Yeah but you yelled and..." He paused as if seeing dad for the first time. "What are you doing in here?"

"Hey, can you guys like talk later? Cause like my chest is hanging out here."

"That's okay Meg," Mark said. "It's not like there's more than you can cover with your hands."

Oh he would pay for that one!

"I'm sorry Hon!" Dad said still facing the door. "I just wanted to let you know we were going to go for a swim and figured you could meet us down there."

"How'd you get in?" Mark asked.

"We have the other key, just in case. I mean I figured since you were sharing the room no one would be undressed."

"Do you mind?!?" I exclaimed.

"Calm down Sis, I'm going." Mark said and rolling his eyes turned and closed the bathroom door behind him.

" I'm Sorry hon," Dad said I could see how red his ears were. "See you at the pool."

Without turning around dad left. Mark came back out and let out a deep breath.

"Damn I almost pissed myself."

I nodded, my heart was pounding so hard it hurt.

"Hey Meg?"

"Yeah?"

"You can uncover your tits now."

I made a show of putting my back to him.

"Trust me Mark after that crack you'll be lucky if you see my tits again."

Part 2: Real Trouble

Mark and I changed into our bathing suits. This time really in separate rooms as I didn't want him to see it right away especially after that crack he had made about my tits. Oh well I would just have to make him spend some extra time on them later. After putting on the skimpy bathing suit which I have to say looked fantastic on my milk white skin. I slipped a robe on after all I didn't want to walk down the hallway in the damn thing. As I tied the robe I found myself looking at the string and picturing being tied up with it, to the point where I took it and wrapped it around my wrist. On the heels of that I envisioned using it to tie Mark's hands together, not only that but have him tied to the bed and make him beg to suck the tits he had just made fun of. I started to get wet. I shook my head and finished tying the robe. Where had that come from all of a sudden? It seemed unnatural for me to want it like that seeing as how I had spent two years of my life being raped. Maybe because it was Mark and I knew he would stop if he thought he was really hurting me. Then again and by his own admission Mark hadn't even thought of the fact it might bother me until it was afterwards he had just wanted to.

"Hey Meg you ready?" Marks voice from the other side of the door interrupted my thoughts . Oh well, I thought with a shrug if we both enjoyed it who cared where it came from, besides it's not like I didn't already know my brother and I were pretty messed up. I exited the bathroom to find Mark standing over near the door looking at it. Like me Mark was wearing his robe but was barefoot as the floors of the hotel were carpeted. As I walked over I smiled seeing Mark's eyes go right to my legs looking them up and down and lingering on my feet with my bright red toe nail polish.

"What are you looking at?" I asked nodding towards the door.

"Doug's got the spare key but this," He tapped a small silver bracket. "Is the security latch, you know so the cleaning lady can't walk in on you."

"You really think he'd walk in after earlier?" I asked.

"I don't want to take stupid chances." Mark said. "We'll just make sure we put this on later."

I nodded and closing the door behind us we made our way down to the pool. It was late December and the hotel was less than a third full. Despite that there were a few people at the pool, a couple of older couples, and a few guys and girls our age probably college students. Mom and dad were sitting in chairs near the edge of the pool, and by the look of their hair they had already jumped in. The room was warm and as soon as we walked over to them. I undid my robe and after seeing that Mark was already looking across at the other girls shrugged and let the robe drop. Instantly my father frowned and even mom who understood that I was almost twenty one and not a little girl anymore gave me a look. The bikini was minimal with the bottom tied high up on my hips and the top tied in the back. My tits weren't the biggest but the top propped them up perfectly.

"Hey," Mark started to say then stopped cold when he saw me.

I had to turn my head to hide my smile as Mark's jaw all but hit the ground. Unfortunately when I looked back it seemed as if dad was watching Mark watch me. No I was just nervous and looking for a problem now.

"So what do you think?" I asked.

"I hope you didn't pay full price for that third of a bikini." Dad said, and then shaking his head added;

"Really Megan that's a bit much no?"

"More like not enough." Mom added.

At that moment a couple of whistles came from the guys on the other side of the pool. Smiling I turned to face them and waved. One guy waved back and his girlfriend punched him in the arm.

"Stop flirting Megan were on vacation." He then stared at my back and shook his head disgustedly. "I don't know what's worse the bikini or that thing on your back that it's showing off."

He was of course referring to the Baphomet tattoo. Dad looked at Mark;

"That's all you Mark! I mean really I can't believe you paid for that for her."

"It was my choice dad."

"Of course it's my fault." Mark said. "Maybe I picked the bikini out for her too."

"Don't get smart Mark." Dad replied.

We were interrupted by another whistle from the other side.

"See Megan?" Dad asked. "That's what you want?"

"Oh come on dad their just having fun, and besides Mark will protect my virtue."

"Few years too late for that." Mark replied.

I punched him in the chest.

"Don't be an ass."

"Whatever." Mark said. "Besides," as he spoke he walked over to the edge of the pool facing the kids across the pool. "If you've got it flaunt it."

With a flourish Mark tossed off his robe and put his arms out to the girls across the pool. He was rewarded with several whistles and one of them clapped. Mark turned around so they could see his back and after pausing to flex his arms turned a back flip landing perfectly then before I could react grabbed me around the waist and effortlessly lifting me off my feet tossed me into the pool. I came up sputtering, looking for Mark. A second later I felt something grab my legs and Mark lifted me up out of the water and tossed me in again.

This time when I came up Mark had swum down to the other end and over to the girls who seemed more than happy to talk to him. The boys did not look as happy, however they cheered up after I swam over to join my brother. For the next half hour Mark and I stayed over there shooting the shit, and flirting our asses off. It turned us on to see others checking us out and knowing that we were going to be together at the end of the night. Of course the fact that I introduced us as brother and sister was a turn on of a different kind. After awhile we went back over to the folks and hung out with them. Dad seemed to be going out of his way to not look at me and made a couple of more "pretty" jokes about Mark until mom told him it wasn't our fault we were young and beautiful. I lied back in the chair with my eyes closed. I swear I could feel my brothers eyes on me. It was warm as hell in the pool room and I felt happy and lazy. Keeping my eyes closed I stretched hoping my brother was getting a good view. Somebody was as I heard another whistle from the other side.

Mom and dad got up and said they were going back and they wanted us to meet them for dinner at eight, it was only five thirty so I figured we had another half hour. I must have dozed because Mark woke me up by kissing me. I came up quick almost hitting him. Was he nuts? A quick look around though showed me that we were the only ones there. Mark smiled at me and getting up took my hand and led me over to the deserted hot tub. We got in and I let out a sigh of pleasure as the hot water jets hit my back and legs. At first Mark sat across from me then after a couple of minutes came around to my side and under the water started to play with my inner thigh then began rubbing my pussy through the bathing suit.

I moaned and smiled at him. Mark smiled back, his hair was wet and his eyes were just about completely green at the moment.

"You really are beautiful Mark." I told him.

"So are you Megan, the most beautiful woman I've ever seen."

With that he leaned over and kissed me. I enjoyed the kiss as long as I dared then pulled away. I did however find his cock under the water and start stroking it through his bathing suit. A moment later however a couple of women came in and directly over to the hot tub. Mark and I got out and as we did I noticed them staring at Mark, I followed their gaze and had to hold in a laugh. My brother was still at least semi hard and the suit left little to the imagination. As he turned and walked away I overheard one of the women say;

"Jesus did you see how big that was?" Her friend replied;

"Matched the rest of him lucky bitch," She then added; "But young probably don't know how to handle it."

I shook my head as I grabbed a towel and went over to Mark. Oh trust me ladies this nasty girl could more than handle my little brother's beautiful cock. As a matter of fact I would be handling it all night long.

We returned to our room where we showered separately, Mark tried to join me but I told him to wait his turn. I had no doubt if Mark got in there with me we'd end up fucking and at this point I wanted to make him wait, besides truth be told I was still sore from earlier. Between the size of his cock and his physical strength my brother was not easy to handle sometimes. I took my time in the shower making sure my pussy would be perfectly smooth for later and then enjoying the hot water on my skin, then after rinsing off reluctantly got out. I wrapped myself in a towel and leaving the bathroom told Mark it was his turn. As my brother went into the bathroom I went over to the bed and dropping the towel set the alarm for an hour from now and slid under the blanket onto the cool crisp sheets. Oh this was sooo nice I thought as I rolled over onto my side and closed my eyes. Between the spa and the hot shower I went right out. I woke up a few minutes later when Mark slid under the covers next to me and after gently kissing my shoulder put his arm around me and pulled me close to him. Damn did this feel good! Apparently Mark thought so as well as he sighed contentedly in my ear.

I didn't want to move when the alarm went off. Screw dinner we could get room service later. I just wanted to lay here curled up with my brother and go right back to sleep. As I stayed there seriously debating trying to get out of dinner, the room phone rang. Mark rolled over and answered it, and of course it was Dad making sure we would be down in the restaurant by 8 god he was so fucking anal sometimes! I rolled over onto my side to face Mark who after hanging up the phone rolled over to me and wrapping his arms around me gave me a kiss and held me close to him.

"Damn you feel good Megan."

"So do you little brother, I could stay here for the rest of the night."

We stayed there for a few minutes and I was suddenly overwhelmed by how good my brother really did feel. Not just physically either, it was emotional as well. I felt a closeness to Mark that I had never even remotely come close to feeling with anyone else. With a groan I pulled away from Mark and sitting up stretched my arms up over my head letting out a startled yelp as Mark reached around and lightly pinched my nipples.

"I love that noise." Mark told me smiling.

"And I love that smile." I replied.

Mark got up and stretched as well. Damn I thought as I watched the muscles in his shoulders and back my little brother was one fine looking man. I finally dragged myself up and told Mark to change in the bathroom. He looked at me questioningly and I told him I didn't want him to see me get dressed. With a shake of his head Mark grabbed the hanging bag that he had brought in with him that contained his dress clothes and went into the bathroom. Going into my bag I put on the see through red lace bra and matching crotch less panties. This way when we came back to the room I would only have to put on the stockings and red heels I had bought.

I put on the one piece red dress I had brought with me and sitting at the small table in the corner spent a few minutes teasing my hair out a little. I had just finished applying my make up when Mark came out of the bathroom. Needless to say he looked fantastic wearing a burgundy colored dress shirt with black slacks he had even put on a black tie. I noticed he had gel in his hair which was bound to get my dad on him again, but I loved it. As I stood up Mark came up behind me and encircling my waist with his arms rested his head on my shoulder.

"Look at us." Mark said referring to the mirror on the wall. I did smiling at him in the mirror.

"Are we not beautiful?" Mark asked. I have to say I agreed.

Dinner seemed to drag forever, probably because I knew that a bottle and my brother's cock were waiting for me on the other side of it. I sat across from Mark next to dad and several times during dinner slipped off my shoe and slid my soft foot up his pants rubbing it along his leg. Each time he looked up I would wink at him. I was getting hornier by the minute, the fact that I was sitting next to my father with my pussy bare under my dress was adding to the overall feeling of lust that was coming over me. At one point mom got up to go to the bathroom, and I raised my foot and put it directly into Mark's crotch, he was hard as a rock and I could feel my pussy begin to drip. Oh what a night this was going to be!

Maybe not just for us either as I couldn't help noticing Mom was wearing her long sandy brown hair down, and was sporting three inch heels and a skirt that was shorter than what she would usually wear. Mark noticed as well as when mom walked away and I had removed my foot from his cock he said;

"You go Doug."

My father grinned and said;

"Trust me Romeo I could show you a few things."

"Please dad," I told him. "I'm trying to eat."

"I don't know Doug," Mark said smirking. "Denise looks out of your league," He shrugged. "You definitely married up."

My father actually laughed at that. It was good to see the two of them getting along. Mom came back and asked what was so funny and Mark told her he was pointing out that she looked hot. Mom blushed but was smiling. Who'd have thought Mark could be a schmooze? Finally after coffee and desert, dad paid the bill and said he was ready to call it a night. The four of us walked back to our rooms. Mom and Dad were in front of us but otherwise the hallway was deserted. I cut in front of Mark and still behind my parents stopped and quickly flipped my skirt up showing off my ass in the red panties. I dropped the skirt and turned to see Mark shake his head and whisper;

"Damn Sis."

We said goodnight to my parents and as soon as their door closed, I grabbed Mark's hand and led him down the hallway to our room. Mark had just closed the door and before he had completely turned around I had my arms around his neck and was kissing him hard. As he eagerly returned the kiss I rubbed my leg up and down his, Mark reached down and caught my ankle holding my leg up his other hand dipped under my dress. Mark grunted in surprise as his fingers found my bare wet pussy. He instantly plunged two of his fingers inside and I moaned into his mouth as we continued to kiss.

Mark's thumb found my clit and started working it in quick hard circles. I broke the kiss and moaned. Then catching myself whispered;

"Not yet little brother I want to play first, I ohhhh."

Mark wasn't listening his thumb was moving faster and as horny as I had been all night I was already getting close to the edge. Putting his mouth to my ear Mark said softly;

"That's it sis, you go ahead and cum nice and quick. That way I can take my time when I suck on that hot fucking pussy of yours."

"Oh yeah little brother? You want to lick your big sisters pussy tonight? Well I think I'll let you I...oh yes! Yesss!"

I came so hard and fast on Mark's fingers that had he not been holding my leg and had his arm around my waist I would have fallen. Mark kept his fingers still as I ground my hips into them, but his thumb continued to move keeping my orgasm going. I let out a soft whimper and fell forward into his arms.
