Siblings with Benefits Ch. 10

With a final twitch of his hips Mark groaned and rolled over onto his back panting as hard as I was. As the two of us lied there sweating and panting covered in each other's cum. I thought Oh Megan you are a dirty little slut letting your little brother take you in your own bed.

"Oh goddamn little brother!" I gasped. "Where did that come from?"

"I was a little worked up from the tournament I guess." He got out in between deep breaths.

"Yeah? When's you're next one? I'm taking the night off."

Mark laughed and we laid there quietly for a couple of minutes before I sat up and slipped my nightshirt back on and lied down on my side. Mark made a sound of protest, but got up and slipped his shorts on neither of us had wanted to make the effort to get dressed but god forbid my parents ever caught us in bed at least if we were dressed there was a chance to explain it. Mark lied down next to me ,and wrapping his arm around my waist nuzzled his face into my hair and kissed my neck.

"Damn Mark I'll tell you even though I said no that was just what I needed."

"That's what I'm here for." Mark replied sounding as exhausted as I felt.

I closed my eyes and sighed contentedly.

"Yeah? you always going to take good care of your big sister?"

"I'll always be here for whatever you need sis, always."

I exhaled loudly as I slumped back into the bed my heart racing. Biting down on my lip so I wouldn't get as loud as I usually did, I had whimpered, as thrusting my hips into my fingers, my index finger dancing across my clit I came hard to that final image of Mark above me, his eyes rolled back, cheeks glistening form his sister's pussy and pumping shot after shot of hot cum inside of me. Lying there spent I had finished recalling how as usual despite the nastiness of the sex my little brother always ended up holding me tight.

I pulled my nightshirt back down and reaching over shut the lamp off to try to sleep. This proved a fruitless venture as my mind continued to spin, between replaying last night with Mark and the barrage of memories being in this room brought back I couldn't settle down. After awhile I reached over and turned the lamp back on.

What the hell was I going to do? Even with not getting much rest last night I was way too wired to sleep, and needed to find something to try to keep my mind occupied. There was no tv in the room, and I had packed quickly not thinking to grab a couple of books from Mark's office. I did have my I-pod but that would still just let my mind drift. Then remembering that mom had said something about books she had found I decided to go take a look in the closet.

I found an old cardboard box on the floor and putting it on the desk began digging through it. There were some old paperbacks and a couple of text books, nothing interesting really, but I continued to take the books out to see everything and then near the very bottom I found it.

"Oh my god." I whispered, as I removed the black leather journal from the box.

The Taboo diary as Mark had always called it, that I had kept off and on for close to ten years. The book was written entirely in Latin and chronicled in detail many of our forbidden sexual exploits. Even Mark had written a few of the earlier entries. I had thought I had lost this when Tommy had broken off our engagement and I moved back here for awhile just before going to Chicago.

Had the folks or anyone else ever read this at any point there would have been hell to pay, but Mark and I figured the Latin was more trouble than anyone would go through and in the end it was a sick thrill to have the thing exist in the first place. All other thoughts forgotten, and with my hands trembling in excitement I brought the book over to the bed and opened it to the first page. I had drawn the circle of the Baphomet complete with all of Levay's symbols, but inside instead of the figure of the goat words written in a mixture of our blood;

Mark and Megan; separated by life Reunited in sin.

I propped up a pillow on the bed and leaned back beginning to flip through some of the entries. The first few I had copied out of my real diary and were about my first thoughts of wanting Mark. I laughed at one entry which described me watching Mark pumping weights in the basement and running upstairs to masturbate to the thought of him pumping me. There was a month worth of these until the last one which ended with me writing that the folks were going away and tonight was the night. It was dated July 9th 1984.

Incredible that we had just been reliving this last night. "Fate" I heard my brothers voice clearly in my head. Mark never believed anything happened that wasn't supposed to the exact way it was supposed to. This book contained a decade of our relationship from the fun to the not so fun as I know I had written many things about my addiction in there. As I looked towards the back of the journal the last group of pages were separated by a piece of paper and a ribbon. Without looking I know I had written the words "Darkest Days" on there.

I knew some of what was written in there but also knew there were things my mind had mercifully blocked out. I would never open those pages. I almost put the book down at that point, but then thought about the fun stuff that was in there, not only that but it was not a coincidence that I found this. I was meant to read it. I started thumbing through again going past our first weekend together, and a few other simple entries of sneaking into each other's beds. I stopped at the entry for our Christmas vacation which had been a fun trip with a scare at the end. Deciding to start there I read slowly at first as I shook the rust off my Latin and then gained speed as I began my journey back through the early years of my forbidden trysts with my little brother.
