Siblings with Benefits Ch. 25

"Go ahead and suck on that clit little brother, just like you did last night, and just like you will tonight."

Mark leaned forward and began tonguing my clit as he slid two fingers inside. I let my head fall back on the pillow and, letting go of my clit, brought my hands up to start teasing my nipples lightly with my fingernails.

"Oh damn that's nice." I said quietly as Mark was now sucking my clit in and out of his mouth in the same slow rhythm that his fingers were pumping my pussy.

Looking back down I saw that Mark had lifted up a little bit and could see his huge cock pointing down into my bed. Staring at his cock I licked my lips and told him;

"Roll over on your back little brother."

"Don't rush sis," Mark started. "I..."

"Little brother, your nasty big sister needs that big hard cock in her mouth; now roll over so we can both have fun."

Knowing what I meant Mark gave me that adorable shy little smile, that no one else who knew him would ever think him capable of and, sliding up from between my legs, rolled over onto his back. I immediately sat up and, crawling forward, I swung my right leg and arm over Mark's hips and, resting on my elbows between his legs, wiggled my hips playfully, showing off my well shaped ass and pretty pink pussy.

"Damn you're fucking hot sis." Mark whispered.

With deliberate slowness I crawled backwards, as I did I kept my body low enough that my hard nipples were just grazing my brother's skin and my long black hair was also tickling across him. Getting impatient, Mark reached forward and, grabbing my legs just over my knees, pulled me backwards until I yelped in surprise as I felt his tongue slide into my ass.

"Oh you naught boy!" I exclaimed as while I worked my legs underneath his shoulders, Mark spread my cheeks wide open and pushed his tongue deeper into my asshole.

Mark's incredible cock was pressed against my chest and, as I leaned up, it sprang to attention in front of my face. Grabbing it in my right hand I pulled it to the side and, bending my head down, started swirling my tongue across my brother's balls. Mark groaned into my ass as I sucked on his balls while slowly pumping and squeezing his throbbing cock.

"Oh yes!" I panted as Mark's tongue left my ass to be replaced by one of his fingers.

I rested my face on his thigh, still jerking his cock and, moaning, Mark worked his finger all the way into my incredibly tight ass and his tongue once again found my hard clit. Picking my head up I slid my tongue up along the side of his shaft and then, losing patience, opened wide and took my brother's cock almost all the way down in one smooth motion.

"Oh yeah," Mark moaned, "Oh damn I missed your mouth sis."

Another comment for a hallmark card, I thought to myself, as I opened wider and took the rest of him down until my upper lip was touching the edge of his balls. After pausing and slowly swirling my tongue around the base of his shaft, I started bobbing my head up and down, going about halfway up the length of Mark's huge prick before sliding back down. My brother moaned as, adding to his pleasure, was the fact that his sucking on my clit had me steadily groaning around his cock.

Reaching around I took Mark's balls in my hand and started gently rubbing them as I continued to blow him. My other hand was still around his cock following the wet trail my mouth was leaving and jerking him off as I sucked on him. My moans started to turn into high pitched whimpers as Mark's fingers were stuffed into both my pussy and ass, as he continued to suck my clit in and out of his mouth.

I started rocking my hips up and down as I could feel myself getting ready to cum. I started letting more of Mark's huge cock out of my mouth before going back down, deep throating him with each long slow suck. I moaned again as I could feel my thighs start to tremble and had just taken Mark's cock from my mouth to tell him to go faster, when suddenly, Mark removed his finger from my ass and, grabbing the back of my head, shoved it all the way back down his cock and, holding it there, started to fuck my mouth.

The turn on of having my brother's enormous cock forced down my throat, coupled with his rapid sucking of my clit, sent me over the edge. I tried to squeal, but all that came out was a whimper as I was cumming with my mouth and throat completely stuffed with my brother's cock. Letting go of his balls I dug my finger nails into his thigh as my hips thrashed wildly and I whimpered and moaned as Mark continued to fuck my mouth. Letting go of his cock I grabbed his other thigh and dug in there as well, squeezing so hard I heard Mark's breath hiss out between his teeth. Letting go of the back of my head Mark slid his hand between us and, grabbing my nipple, gave it a hard pinch.

I pulled my head from my brother's cock and let out one long loud moan as the last of the orgasm flowed through me. I leaned back and, grinding my pussy once more into Mark's face, gasped out;

"Damn I came hard I... Ohhh look at that cock." I whispered.

Mark's cock was so hard and swollen the head was turning purple. With no hesitation I slid forward and down my brother's body until my legs were once again straddling his hips. Leaning forward I grabbed Mark's ankles and, pulling my legs up, got my feet flat on the bed until I was squatting over my brother's massive cock. Not needing to be told, Mark reached down and, grabbing his cock, held it straight up and placed the tip directly at the edge of my pussy. I lifted up a little more then, letting my weight go, plunged downward, driving Mark's huge dick deep into my sopping wet pussy.

"Oh fuck that's deep!!" I exclaimed loudly as my ass touched Mark's stomach and I was completely impaled on his cock.

"Shhh!" Mark groaned out.

Using my legs I started bouncing up and down on Mark's throbbing prick. It had been a long time and even after last night I wasn't used to him yet and, for the next couple of minutes, worked myself up and down so slowly that my brother was moaning with every stroke, desperately wanting to fuck me.

"Awww do you want to slam your big sister's pussy, little brother?" I asked.

"Oh please go faster sis, I need to cum." Mark whimpered.

"Ooooh," I cooed, as I once again slowly descended an inch at a time down my brother's long thick cock. "And where do you want to cum little brother?"

"Inside of my big sister's pussy." Mark answered.

"I don't care how old we are, that will never get old."

I then let out a loud moan as I once again came all the way down. My pussy was stretched to the limit and it felt incredible. Mark made one of those adorable little whimpering noises as, while still with Mark buried to the hilt inside of me, I wiggled my ass back and forth.

"Oh please sis I... ohhhh." Mark whimpered again. "Oh don't tease me."

What could I say to that?

"Just stay still little brother," I told him. "And let your nasty big sister give you what you need."

I gently drew Mark's cock all the way out then, after a moment's hesitation, drove myself back down hard and immediately came back up again. Leaning over even further I bit my lip and started bouncing up and down on Mark's cock as hard and fast as I could. Mark reached out and, grabbing my hips, started lifting and pulling me, slamming his cock even deeper into my pussy. Despite my best efforts not to, I started yelping every time I dropped myself onto my brother's cock. Reaching out Mark grabbed my legs over my knees and yanked hard.

I fell backwards on top of him and, before I could react, Mark reached around and, covering my mouth with his hand, held my left leg up from the back of my knee and started thrusting his hips wildly, slamming his huge prick into me as I lay on top of him with my back to his chest. I squealed loudly into his hand over and over as Mark, no longer worried about the noise, or at this point even whether or not it hurt, continued to fuck the shit out of me. Reaching down I grabbed the base of Mark's shaft and started jerking him off as he fucked me.

"Oh fuck yeah sis!" Mark exclaimed. "Oh just like that! I..."

Mark let out a loud gasp as his cock exploded inside of me, sending an enormous spurt of cum into his big sister's thirsty pussy. Mark stopped pumping his hips as I continued to jerk him off, each stroke of my hand producing another shot of hot cum. Mark was moaning and whimpering in my ear and the sound was driving me crazy.

"Oh oh yeah sis, oh damn." Mark panted and, after a couple of more strokes of my hand, reached down and grabbed my wrist.

"Okay." He whispered.

I gave his cock one more playful squeeze then, rolling off of him onto my stomach(,) said;

"Goddamn that's the way to wake up!"

Mark lied there silently for a minute then said;

"Hey sis, know what else I missed?"

"Is it what I hope it is?" I asked expectantly.

Without another word, Mark rolled off the bed and, taking my hand, pulled me up into a sitting position.

"I... hey!"

I laughed out loud as Mark swung his arms underneath me and effortlessly lifted me up off the bed. Turning Mark carried me into the bathroom where, after putting me down, he turned the shower on and, pulling the curtain aside, gestured me in. Giggling like a schoolgirl I hopped under the hot water and moaned in pleasure as, getting in behind me, Mark wrapped his arms around me and, after kissing my neck, grabbed the soap and, starting at my shoulders, began gently washing every inch of my body, even dropping to his knees and getting the bottoms of my feet and, of course, burying his face into my ass.

Standing back up, Mark pushed me in the back and, taking the hint, I put my hands against the shower wall and bent over. Mark reached around and, as his thumb found my clit, shoved his once again hard cock into me from behind.

"Oh yes, oh give it to me little brother!" I told him looking over my shoulder and admiring his incredible body dripping wet from the shower. "Go ahead and slam that pussy, it's all yours baby!"

Mark grabbed my hair with his free hand and, rearing back, started fucking the living shit out of me. I was once again yelping with every thrust and could already feel my body responding to Mark's stroking of my clit. Feeling my legs begin to tremble Mark let go of my hair and, wrapping his arm around my waist, held me close as he started driving his cock into my sore but still needy pussy. Unable to help myself I let out a loud howl of ecstasy as my second orgasm in the last fifteen minutes tore through me. Letting go of my waist Mark, once again, reached around and covered my mouth as I slammed my hips back into his cock harder and harder as wave after wave of pleasure crashed through me.

Mark let out a loud moan of his own, as my pussy contracting around his cock sent him over the edge and he, once again, began painting the inside of his big sister's pussy with his hot sticky cum. I whimpered into my brother's hand as the last of the orgasm flowed through me and, had he not shifted his hand from my clit to grab me around my hips, I would have fallen in the shower.

"Oh damn." I whispered, leaning back into his wet body. "I think I could go back to sleep."

"We got time." Mark whispered then, kissing me gently on the neck, said; "Sis I missed this so much."

I turned around and, wrapping my arms around his shoulders, gave him a long lingering kiss. It couldn't get any better than this! The hot water, steam and my brother's amazing body pressed against mine after having just fucked me twice. The water began to get cold and, after Mark shut it off, he stepped out of the shower and, grabbing a towel, held it out for me. Smiling from ear to ear I got out and let Mark wrap it around me and gently pat me dry.

"You coming back to bed with me little brother?" I asked batting my eyes at him. "You gonna come back and hold your sister?"

"Damn straight." Mark said as he started drying himself off. "I..."

We both jumped at a loud knock.

"Hey Mark you up?" Dad called from Mark's side of the bathroom.

"Shit," Mark said rolling his eyes. "Just like when we were kids."

Quickly stepping over to the bathroom door Mark opened it and called out;

"Give me a minute! I'm just getting out of the shower."

"What the hell does he want this early?" I whispered.

"Who the hell knows, maybe he thinks we're back in the day and I'm supposed to mow the fucking lawn or something."

Mark finished drying off and, giving me a quick kiss, said;

"Go back to bed Meg, I'll meet you back in there if I can."

Mark turned and, walking into his room, closed the bathroom door behind him. I was getting ready to go back into my room when I noticed that the doorknob was still missing from Mark's door. I had an instant image of kneeling on the floor and playing with myself while watching Mark fuck Krissy. I stared at the door and found myself wondering what dad wanted. Looking once again at the hole where the doorknob used to be I thought... no, I told myself, I couldn't. Next thing I knew I was on my knees again like a nosy teenager, looking through the hole into Mark's old bedroom.

Mark had tossed on a pair of jeans and was just opening the door to let dad in.

"You still lock your door huh?" dad asked.

"Yup," Mark answered. "Old habits die hard."

"I guess." Dad said looking around a little nervously. Then, focusing on Mark, he looked him up and down and shaking his head said;

"Damn Mark every time I see you I swear you're bigger."

"That's what she said." Mark replied smirking.

Dad rolled his eyes and Mark asked;

"Is everything okay?"

"Yeah, I just wanted to talk to you for a minute."

"Okay."

"Listen Mark," Dad began. "I just wanted..." he paused then taking a deep breath said; "I just wanted to tell you thank you."

"For?" Mark asked.

"For this Mark." With that dad pointed towards the bathroom door I was kneeling behind. "For Megan, for everything you did for her and us."

"Doug you said thank you before." Mark said. "It's okay, I..."

"No Mark, there's a little more."

My father's voice sounded funny and, leaning a little closer to the hole, I could see he was starting to cry. Mark saw it too and the awkward look on his face was priceless. Before Mark could say anything my father stepped forward and, putting his arms around my brother's shoulders, looked into his face and continued;

"Thank you for saving my daughter's life Mark, for bringing her back to us."

"I saved my sister's life Doug." Mark pointed out. "I mean..."

"No Mark, "Dad interrupted. "I mean yes you saved your sister, but you're not telling me that part of the reason you went up there wasn't for your mother. I mean maybe it wasn't for me, god knows I didn't treat you well enough the last few years to deserve anything, but I know you went for Denise as much as for yourself. I know you love your mother."

"I..." Mark started but before he could finish my father hugged him and began speaking haltingly, his voice choking with emotion.

"You're a hell of a brother Mark, and a good man." My father stopped for a minute and said so softly I could barely hear him. "And I feel terrible it took this long for me to tell you this, but you are one hell of a son Mark."

From where I was I couldn't see dad's face, but I could see my brother's. Mark's eyes looked like they were tearing up and mine were as well. I knew I should probably feel bad for eavesdropping like this, but was glad that I was seeing this touching moment between the two most important men in my life.

"I had a hell of an example Doug."

My father stepped back and, wiping at his eyes, said;

"I'm sorry we fought Mark, it was my fault and you were right, I had given up, but you never did and I feel terrible about it."

"What's done is done Doug." Mark said simply. "All that matters is Meg's okay and every one's happy."

"No Mark, what matters is all of us are okay now, and I never want us to fight like that again." Dad clapped Mark on the shoulder and said; "I mean it Mark, you really are my son and I don't want you to ever forget that."
