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.”
