As I watched for minute as she rolled over onto her side her back to me. I could tell by her breathing she had already gone back to sleep that is if she had ever really been awake at all. I went to the bathroom thinking it felt strange to be walking around naked but it also felt good. I had nothing to be ashamed of last night proved that. The look on Megan’s face when she had seen my cock had erased any doubt I might have had that I was pretty well hung. I stood there in the bathroom for a couple of minutes trying to clear my mind of any thoughts of my sister as it’s impossible to piss with a hard on.
Standing there I glanced to the left and saw that Megan had left the door to her side of the bathroom open. I found myself looking at her big double bed wondering if I’d get a chance to fuck her in there. Listen to yourself you sick fuck I thought then shrugged what the hell? I’d never claimed not to be. Finally I was able to go, then after taking a minute brush my teeth, I looked in the mirror and flashed the perfect smile that all the girls seemed to love. It was fake of course but they didn’t know that.
I never doubted that I was attractive. I’d had enough girls, even older ones check me out and Krissy was always telling me I was hot. Never mind Megan’s friend Betty who one day all but offered to drop to her knees for me. Despite that I had always felt a little insecure as what good is having it if you’re not using it? Well last night had changed all that! I really did feel different I wasn’t an eighteen year old virgin anymore I had crossed the line and become a man. I frowned at the thought of Krissy however hadn’t last night been cheating on her?
I shook my head that was a problem for another time, not now when I had a naked twenty year old in my bed. Bottom line was I now felt complete, confident in every way, ready to do what Levay and Crowley as well as my sister talked about I was ready to take what I want and what I wanted was lying not ten feet away.
I left the bathroom and stopped just outside the doorway where I stood spellbound by the sight of my big sister naked in my bed. Megan was lying on her stomach facing away from me, the sheet only pulled up to her waist and one of her amazingly long legs was sticking out all the way to the thigh. The sheets were black and her ivory skin looked sexy as hell against them as did her long dark hair fanned across her back. Even her bare foot with the bright red toe nail polish looked good. Oh let’s face it everything about my sister was hot.
My cock became rock hard in an instant and my heart began to beat faster. I walked quietly up to the bed stood there hesitating for a moment. Oh this is so wrong I told myself but oh did I want her. Before I could change my mind I took a deep breath and whispered;
“Take what you want Mark.”
I carefully got onto the bed lying on my side next to her, and after taking another long look at her amazing body lightly caressed her back enjoying the feel of her soft skin. Megan made a cute little noise in her throat but didn’t stir. I had an image of rolling over on top of her and just taking it but she was sleeping and after what had happened to her… I shook off those thoughts and leaning over gently kissed the middle of her back. After being rewarded with another of those little noises I started slowly working my way up her back one little kiss at a time.
For each kiss I received another soft moan. I was pretty sure she was awake at this point and was dying to roll her over but at the same time was enjoying not only kissing her but her reaction to it. Reaching the top I slid her hair to the side to give the back of her a neck a longer kiss. At this Megan moaned;
“Oh Mark, that is sooo nice.”
That sent a thrill through me as did her leaning her head back so I could nuzzle deeper into her. I gave the smooth flesh between her neck and shoulder a lingering kiss opening my mouth and gently sucking then slid my mouth up to her ear where I gave her earlobe a playful nibble.
“Little brother, are you looking for something?” She asked quietly.
“Oh yeah.” I answered before going back to her neck as I did my hand slid down her back and I gave her firm ass a squeeze.
“Ooooh.” Megan cooed. “Look at you being a bad boy and coming after your sister.”
As she spoke she pushed herself up onto her side so her back was against me. I could feel my cock throbbing against her ass. I went to put my arm around her waist but Megan grabbed it placing my hand on her left tit instead. I immediately started rolling her nipple between my fingers like she showed me last night.
“Is that what you’re doing little brother? You coming after it?”
“Yes.” I groaned as she began grinding her ass up and down on my cock.
“Then tell me what you want.”
“I want you.” I told her pulling on her arm to get her to roll over but she held herself back.
“Better than that little brother. Tell your nasty big sister what you really want.”
“I want to fuck you again.”
“Yeah?” She asked working her ass harder against me. “You want to fuck your nasty girl again Mark?”
“Oh I do.” I moaned out, as lifting her leg Megan reached down between them grabbing the tip of my cock and giving it a squeeze.
“You mean you want to fuck your sister isn’t that right Mark?”
She rubbed my cock along her pussy which was soaking wet causing me to let out another of those impatient whimpers from last night.
“Well that’s too bad Mark,” She began as she put her foot on my thigh then holding my painfully hard prick started grinding her pussy up and down on it. “Because you said last night it didn’t seem right.”
“I..” I didn’t know what to say but she was teasing the hell out of me and to make it worse she put her pussy on the tip of my cock letting it go in a little before pulling it back out.
“Oh don’t tease Megan please I’m sorry I said that I…”
“I am too little brother. We could have had a lot of fun this morning, hell all the time I mean my rooms right next door.”
Letting go of my cock Megan slid her hand down and started rubbing my balls which felt like they were ready to explode.
“That’s right Mark you could have had plenty of this pussy but seeing you think its wrong.” She let go of me completely also pulling my hand from her tit. “I think maybe I should just go back to my bed.”
With that she made to roll away from me but I held onto her arm. I was getting desperate.
“Please don’t go Megan! I want to! I really do I…” I hesitated then added; “I need you.”
“Is it me you need or is it my hot little pussy Mark?”
“Both.” I told her honestly.
“That’s a good answer little brother. MMM.” She made as if she were thinking all the while slowly grinding her ass against my cock.
“Tell you what little brother. I think you’re right, it is wrong.”
“No really,” I began but she continued.
“But like I told you last night I really don’t care. I don’t think you do either but I want to hear it Mark.”
Megan once again put her leg up on me grabbing my cock.
“I want to hear you tell me what a bad boy you are and how bad you want to be, and with who. I want you to tell me who you want.”
Last night Megan had to coax me to talk dirty to her as it really hadn’t seemed right, but she was holding me right at her pussy and more than that had pretty much said we could do this all the time! I didn’t hold back, if my nasty sister needed me to be a bad boy then that’s what she would get.
“I want to fuck you Megan,” I told her. “I want to shove my hard fucking cock into my hot big sister’s tight pussy.”
“Oooh I like that.” Megan breathed and I knew she did as she squeezed my dripping cock even harder pushing it against her pussy.
“I loved it last night! I loved watching my nasty sister suck me off then let me fuck the shit out of her.” I continued as Megan grabbed my hand putting it back on her tit moaning as I started playing with it.
“I know it’s wrong.” I whispered in her ear. “But I need it Megan your bad little brother needs to feel his beautiful sister’s hot wet pussy.”
Taking a chance I pushed my cock into her a couple of inches. Megan didn’t fight it but I didn’t want to push my luck instead I deliberately used the little whimper she had said she loved begging;
“Oh please Megan please let me have it. I need it so bad.”
“Oh little brother that was just right! Go ahead slam that big fucking dick into your sister’s pussy.”
I didn’t have to be told twice; with a hard thrust of my hips I drove my cock all the way. Megan let out a yelp.
“Damn that’s a big fucking cock!” She exclaimed. I started fucking her but slowly not wanting to hurt her even though it was teasing the shit out of me.
“Oh yeah,” Megan moaned. “That’s it nice and slow.’ I leaned in kissing her neck again.
Megan grabbed my hand off her tit and put it down between her legs. My thumb found her clit and I started rubbing in small circles.
“Ohhhh little brother you are a quick learner, aren’t you?”
“You’re a great teacher.” I said in her ear as I continued to thrust in and out of her. I had never even thought of this position.
“Hey Mark,” Megan whispered. “Look in the mirror.”
I looked up at the mirror on the bureau across from us.
“Oh damn,” I said softly.
In the mirror I had a perfect view of Megan on her side, her leg up on mine, and my cock sliding in and out of her pussy while I played with her. My head was on her shoulder and our faces were side by side. I also saw that Megan was playing with her other nipple, and had that same wild look on her face she had last night. I stared transfixed by the sight of me fucking my sister, my huge cock sliding almost all the way out while the two of us played with her perfect tits.
