"Why so nervous?" I asked putting my hand on his shoulder and lightly running my nails down his arm. "I don't bite." I laughed "Well I guess that's not entirely true now is it?"

"No, I think I have some marks somewhere." Mark said softly, still looking away from me.

After a minute I noticed his eyes went down to the floor and it hit me that with the mirrors, it was the only place he couldn't see me.

"Mark look at me."

Mark slowly turned his head to face me.

"You know little brother," I began. "I've been here four days now and I have to say that I am starting to feel quite neglected."

"Look sis," Mark started, but I put my finger to his lips.

"What's the matter Mark? You don't find your big sister attractive anymore?"

"You're beautiful Megan." Mark said. "It's not that, I just..."

"Come on baby," I said softly. Leaning over I pushed my lips out and whispered;

"Don't you want to kiss me?"

As Mark stared at me I had a sudden flashback. I was twenty and Mark was eighteen. I was sitting there in my red panties and lace tank top asking Mark if he wanted to kiss me. He had been nervous as he was now and I had been horny and nervous as well. After all it wasn't everyday that a sister planned to take her brother's virginity.

"Megan..." Mark started as he looked away from me again. "I..."

"Mark, listen to me." I said, as reaching out, I put my finger under his chin and turned his head to face me again."

"It's over baby, you sent her away Mark. You ended it. You had your reasons and I'm sure they were good ones."

Mark put his head down, and I let my hand trail from his chin to his face where I caressed his cheek.

"But it's time to move on Mark. It's not like your betraying her you..." I hesitated as I recalled my feelings about my brother years ago. "You turned her loose Mark, gave her a chance to be happy with someone who could give her what she needed."

"I know but Meg, it's not that..."

"Look Mark it's not like you're running out and finding a new pet or a stand." I gave him a big smile, and leaning in and kissing his neck, began whispering in his ear.

"It's me Mark, your big sister who always knows just how to make it better."

Mark swallowed hard as I quickly flicked my tongue out across his earlobe.

"Come on Mark trust me," I reached out, placing my hand on his chest and started to tease his left nipple with my fingernails.

I kissed his neck again.

"Your big sister has just what you need baby, so just lie back and let her give it to you."

Mark turned to face me and leaned his face into my hand. I started to kiss him but he pulled back.

"I... Ow!"

As Mark had started, I moved my hand to the back of his head and yanked hard on his hair. Enough was enough.

"Maybe the problem is you've forgotten how to take me Mark." I said, squeezing his nipple hard and causing his breath to hiss between his teeth. "You've gotten soft little brother. Maybe what you need is for your sister to remind you what it's like to be taken. I..."

I stopped as Mark reached up, and grabbing my hand removed it from his hair. Still holding my hand Mark looked at me and whispered softly;

"I...I don't want to play the game Megan," He put his head down and continued; "Please don't make it rough."

I stared at my brother and felt my heart go out to him. In all the years we had been playing I had used different approaches on him. Dominant, submissive, little girl cute and queen of the night dark; they all worked depending on his mood. Looking at him now and hearing the sadness in his voice I realized that none of those would work. My brother didn't need sex he needed love. Mark looked up at me, and started to say something. I reached up and taking his hands in my face, I pulled him to me and gently kissed him. Mark returned the kiss briefly, but tried to pull away. I held onto his face and whispered into his lips.

"Easy baby, just let me."

I kissed him again, letting his face go and sliding my arms around his shoulders. With a soft groan Mark began to kiss me back. I held my lips to his, sliding them back and forth across his mouth. I emitted a groan of my own as I felt my brother's arms slip around my waist drawing me closer to him. I could feel my nipples pressing against his chest through the thin silk and yearned to remove the robe. Instead I continued my soft slow teasing kisses. I slipped my tongue out, and as Mark's lips parted slid it inside his mouth. My brother's tongue played across mine and I could feel his hands trembling on my back.

Once again I was transported back to our first night as lovers. Our first deep passionate kiss during which, like tonight, my brother had been both excited but nervous. I felt as if I was taking him all over again, and the thought caused my pussy to begin to flow. I let my hands travel down Mark's back enjoying the feeling of his hard muscles, and bringing them down to his sides slipped my right one down into his lap.

"Hmmm" I moaned into his mouth as I felt how hard he was.

I worked my lips away from his lowering my head and started kissing his neck. Mark moaned, his hand coming up my back and running through my long still damp hair. I gave his cock a hard squeeze through his pants and felt Mark's hand grab a handful of my hair as he sighed in my ear.

"There you go honey," I said softly. "Just let yourself go."

Pulling away I lifted my leg, swinging it over him so that I was straddling him. Mark titled his head up to me and lowering my face down I began kissing him. As my lips once again teased across his, I started slowly rocking on his lap. Mark began breathing heavier, and putting his hands on my hips started guiding me as I slid across him. I whimpered into his mouth at how good, even through the pants, his hard cock pressing into my pussy felt. I reached down between us, pulling on the tie of the robe causing it to fall open.

I began to pull my lips from his, but Mark reached up holding the back of my head, and kissing me harder. I could feel the urgency in his kiss and surrendered to it, letting his mouth devour mine. As we shared one of the deepest most passionate kisses I could remember, I stopped sliding across his lap, and began slowly twisting my hips, rubbing my hard nipples across his chest. Mark groaned, and breaking the kiss, slid his lips down to first the soft white skin of my throat, then lowering his head began to lick my right tit.

I arched my back allowing him to be able to suck my nipple into his mouth. Looking up I smiled at my reflection as I saw myself on my brother's lap, his face buried in my tits. I could feel Mark's huge cock throbbing against my hot pussy. I turned on Mark's lap, offering my other tit to him. As he eagerly sucked it into his mouth, I ran my hands up and down his back, groaning at how good his hard muscles felt beneath me touch. Speaking of hard, I'd taken my time and still planned to, but right now I needed to not have anything between my flesh and my brother's beautiful cock.

Easing my tit from Mark's mouth, I slid off of his lap onto my knees.

"Stand up baby."

Mark did as I said, and still forcing myself to go slowly, I rose up onto my knees kissing and licking his hard flat stomach. Mark rested his hands on my shoulders and I could feel them trembling, but now more in anticipation than nervousness. Continuing to playfully flick my tongue across his stomach I brought my hands up, grabbing his pants and sliding them down. Mark's huge dick sprang free, and it was an act of will not to immediately take it into my mouth. Instead, grabbing it in my right hand I began slowly stroking it while trailing my lips down his stomach to the soft flesh between his hip and his cock.

As Mark's hands slid up into my hair, I turned my face rubbing his throbbing cock along my cheek. My already wet pussy began to flow even more as I felt my cheek becoming wet from Mark's dripping prick. Looking up into his eyes I asked;

"See baby not so bad is it?" I gave the tip of his cock a quick kiss. "Just your hot big sister taking care of her beautiful little brother."

I took just the tip of Mark's cock in my mouth and gave it a quick hard suck. His hips twitched and I moaned in pleasure as I received a squirt of his salty precum. Putting my hands on his stomach and lightly caressing with my finger nails, I slowly took several inches of my brother's long thick cock into my mouth. With a sigh of pleasure I started bobbing my head gently, sliding his hard flesh in and out of my soft full lips. Mark's fingers were running through my hair, and he was moaning softly as I slowly blew him. I slid my hands from his stomach to his thighs, then the back his legs. I trailed my finger nails behind his knees and traced them up along the sensitive skin of the inside of his thighs.

"Oh that feels nice." Mark whispered.

My hands reached the tops of his thighs, and meeting at his balls, started massaging them as I took his cock deeper down my throat. Mark's hips started rocking in time with my sucking, and I could feel his thighs starting to quiver. I removed his cock from my mouth, and standing up in front of him kissed him hard, slipping my tongue into his mouth and letting him taste himself from my mouth. Mark's right hand dropped down, and I moaned loudly as his fingers slid through my moist lips before plunging into my hot pussy. I put my right foot up onto the bed allowing Mark's fingers to be able to slide deeper inside of me. I lolled my head back and moaned again as my brother's soft lips fastened themselves to my neck. I began rocking my hips into his fingers, whimpering as his thumb found my clit. After enjoying his talented fingers for a minute I pushed against his shoulders;

"We have all night baby; right now you just lie down and let your sister enjoy you."

Mark obediently lied back, and as I pointed towards the headboard, slid himself all the way up onto the bed. Standing there at the foot of the bed I watched my reflection in the mirror as I slowly let the rope slip from my shoulders. My eyes left the mirror and I smiled at the look of pure desire on my brother's face as he took in his big sister's naked body.

"Oh, there you go honey," I said softly, as putting my hands on the bed, I started crawling up to him. "That's the look I love to see."

Mark's eyes widened and I could see his chest rising and falling faster as he watched me crawl up the bed until my head was just over his cock. I swung my head back and forth, letting my long wet hair tickle his thighs and stomach. I groaned as Mark's hands reached down cupping my tits and playing with my nipples. Opening my mouth, I plunged my head down taking Mark's massive cock all the way down to the base of his shaft. Mark gasped as I immediately started sucking him hard and fas, sliding his cock almost all the way out of my mouth before sliding it all the way back in again. I moaned as well, not just from his fingers on my nipples, but at the sensation of having my mouth full of my brother's hard flesh.

I slipped one of my legs over Mark's and started rocking, sliding my wet pussy across his thigh. Mark moaned, and reaching down grabbed my shoulders and pulled. I removed Mark's cock from my lips and smiled at him. I would have had no issue sucking him off first time around, but was thrilled that he wanted to be inside of me instead. I crawled up further letting my nipples slide across his stomach and chest as I made my way up to him. Stopping when my face was over his, I lowered my lips to his, as one at a time I swung my legs over his hips

Still kissing him, I reached down between my legs grabbing Mark's cock and guiding it to my pussy. I slid my lips from his, and started nibbling his ear as rocking back and forth, I teased us both by sliding the head of his cock through the wet folds of my pussy.

"Don't tease." Mark whispered softly.

Resisting the urge to tell him that he had been the one teasing, I rocked back and let my weight go. We both cried out as I impaled myself on his massive cock. Bracing my hands on his chest I pushed myself straight up and started working my hips. Once more I found myself staring at my reflection, watching myself ride my little brother. Mark's hands reached up finding my nipples. Grabbing his wrists I held his hands to my tits, moaning at how good Mark's dark hands looked on my ivory skin. My brother's hands were large, and my tits were on the small side, so that his palms completely covered them and I feel the barbells being pressed back into my flesh.

"Oh yes!" I moaned, as Mark's left hand dropped down and his thumb pressed into my swollen clit.

I squirmed on his cock as his thumb started working my clit in slow circles. I moaned but reached down to move his hand. I could cum later, right now I just wanted him to enjoy. As I tried to pull Mark's wrist away he resisted and whispered;

"I want to feel you cum on me I..." he hesitated. "I want to hear you enjoy me."

Well who was I to argue with that? Removing my hands from his chest, I leaned back until my hands were grasping his ankles. At that angle Mark's cock was bent down and couldn't penetrate me as deeply, but it did allow his fingers better access to my throbbing clit. Sliding my legs out so that my feet were flat on the bed next to his head I started raising and lowering myself as his thumb massaged my clit. Mark whimpered as fucking him like that was teasing him, but I also saw him looking up into the mirrored ceiling enjoying the site of our bodies stretched out across each other. As our eyes met in the mirror, I gave him a wink before letting my head loll back in pleasure as I could already feel the beginnings of an orgasm building deep within me.

I started pumping myself up and down faster and harder. Mark brought his right hand to my pussy using his fingers to spread it open as his thumb began moving faster and pushing harder. I started moaning continuously and let out a surprised squeal as; turning his head Mark flicked his tongue out, licking the tips of my toes which were right near his head. I raised my foot allowing Mark to suck my toes into his mouth. As his tongue swirled around them he removed his thumb from my clit and pinched it between his fingers.

I threw my head back squealing loudly as the delicious mix of pleasure tinged with pain sent me over the edge. I bucked my hips as hard as I could, moaning at the incredible feeling of my pussy contracting around my brother's huge hard dick. Mark was moaning as well, and I could feel his hips moving as he strained to drive his cock deeper into his sister's convulsing pussy. I pushed myself straight up, and leaning forward put my hands on Mark's chest allowing his cock to plunge all the way into my hot little box as I continued to cum. With a long sigh I let myself lean forward until I was lying on top of my brother as the last of the powerful orgasm passed through me.

"Ohhh little brother, oh damn that felt good." I whispered.

Mark's hands found my hips, and taking his hint I started pumping them up and down. I lifted myself from his chest and kissed him. Mark groaned, and started slowly driving his hips up into me. I tried to break the kiss and push myself up so I could ride him harder, but my brother's arms slid up around my shoulders pulling me back into him. Mark kissed my neck then whispered in my ear;

"No, like this."

"You miss your sister's pussy little brother?" I asked softly as I began rocking in time with his slow thrusting.

"I...I miss my sister." Mark said softly. "Please stay right here Megan, stay close to me."

"Always Mark," I whispered in his ear. "Your sister will always be close to you."

Mark's hands went down around my waist, as I slid my arms beneath his and around his back. Mark moaned softly in my ear and squeezed me even tighter. I kissed his neck sighing softly at how good his body felt this close to mine. I could feel my nipples pressing into the hard muscles of his chest, and his strong hands felt amazing. Mark still had one arm around my waist, but his left had moved up and was in the middle of my back gently holding me to him. I couldn't move my hips much in this position, but Mark didn't seem to mind as his hips kept up a slow steady rhythm. Normally sex this slow would tease me, making me want to fuck faster, but as we laid there with our arms wrapped around each other, I found myself enjoying it.

I turned my head and started nibbling on Mark's ear as he continued to give me those amazing long slow thrusts. Mark was breathing softly in my ear and I could feel his heart beating against mine as our bodies became one. I lifted my head pressing my lips to his, engaging him in a long slow passionate kiss. Mark made a whimpering sound in his throat, and he pulled me even closer to him. Breaking the kiss I spoke quietly in his ear.

"There you go baby, anyway you want me that's how you can have me."

I paused to groan as he started fucking me a little faster. I heard him gasp in my ear as his own orgasm approached.

"Oh yeah honey, let it go and give it to me."

Mark was thrusting even harder and whimpering with each one. I smiled into his neck as I loved those adorable little sounds. I wrapped my arms around him even tighte,r and once more found his lips. Mark groaned in his throat, his arms crushing me too him as gave me several hard fast pumps that caused me to release a series of small yips into his mouth. Mark pulled his lips from mine, and let out a long shuddering moan. I released one of my own as I felt my brother's cock twitch and send a long hot stream of cum into his big sister's wet hot pussy. As Mark continued to pump me, I lied still, letting him give me all that he had. At the end of each thrust I clenched my pussy around him, milking every drop I could from his cock and getting him to emit those precious little whimpers.

Mark stopped pumping and I felt his body relax beneath me. I stayed where I was however, my arms around him, and my face nuzzled into his neck. Mark was breathing hard in my ear and I smiled as I could feel his heart beating against my chest. I started to slide my arms out from under him but Mark held me tight so I just let myself relax into him. We stayed that way for awhile and I let out a contented sigh as I could feel his cock growing soft within me. Mark's breathing had not only slowed down but was becoming deep and steady, and I realized that he was falling asleep.

Sliding my arms out from underneath of him I rolled over onto my side. Mark looked over at me and gave me a tired smile. I smiled back at him enjoying the look of satisfaction on his face. For the first time since I'd arrived here four days ago Mark looked as if he were okay. Mark stretched his arm out and curling up next to him I rested my head on his shoulder as I put my arm around his waist and draped my leg over his.

"Feel better little brother?"

"You were right Megan, you're always what I need."

"Of course I am baby, sleeping with me is just like coming home no?" I said thinking how twisted, but true that was.

Mark was quiet and I thought he might have fallen asleep. A minute later he sighed and whispered;

"We look so perfect together."

I turned my head to look up at the mirror and smiled at the sight of the two of us lying in each other's arms. We both looked peaceful and satisfied.

"Well what is it you always said," I asked. "Two parts of the same whole?"

Mark was silent again but I could see his eyes open. He also had a thoughtful expression on his face as if he were remembering something.

"Yeah, I have always said that haven't I?"

"You have." I sighed. "Close your eyes and get some sleep baby, and for the record Mark? You are not going to the gym tomorrow morning."

"I'm not?" Mark asked sleepily as his eyes did appear to be closing even as he spoke.
