Siblings with benefits

Megan turned her face up to meet mine and we began to kiss however I noticed that we were both keeping our eyes open so we could watch. Goddamn did the two of us look good! Megan slid her hand beneath mine spreading her lips open to give my thumb more of her clit and I started rubbing faster. We were still kissing and she groaned into my mouth. Unable to hold myself back I started pumping her faster. Megan took her mouth from mine and gasped;

"Don't cum yet! I want to move." As bad as I wanted to I stopped pumping her, but when she went to move I held her to me speeding up my thumb wanting her to cum on my cock the way she had last night.

"Oh oh oh!" Megan moaned out and dropped her leg, squeezing my cock into her pussy even tighter.

"Oh yeah little brother oh just like that ohhhhhh!" Megan ground her hips back and forth on me and it was everything I could do not to pump her and cum as well. Megan stopped moving letting herself slump into me panting.

"Oh I came soooo hard." She breathed out. Then added; "Don't worry little brother give me a minute and your sister will take good care of you." She winked at me in the mirror. "Even give you a little treat."

I hoped it was soon because damn I needed to cum. I sighed as Megan eased herself off of my cock .

"Lie on your back."

As I lied back Megan rolled over onto her side and putting her head on my chest started tonguing my right nipple. It felt better than I thought it would have. I let out a sigh as my sister worked her way down my chest and stomach slowly kissing and licking taking her time knowing I was dying for her to get to my throbbing prick. Finally she did immediately taking the entire length down her throat. The back of her head was toward me, and I was disappointed I couldn't see but then turned my head my eyes widening as I watched her sucking it in the mirror.

At that point I was glad we had stopped for a few minutes or I would have cum right then. Megan was moaning in her throat as she bobbed her head up and down. Once again it was a turn on that she was loved sucking it that much. There was more to it than that though as she stopped sucking and sitting up looked at me with a look on her face I would come to realize later as pure lust and said;

"Oh you are a naughty boy aren't you Mark?"

"Oh yeah."

"Know how I know?" She whispered. "Because your cock tastes like your big sister's pussy."

At that she put her head down sucking on it some more. She could taste herself off me and she loved it! Oh it couldn't get any better than this could it? Megan stopped sucking then sitting up swung her left leg over my hips and grabbing my cock guided it to her pussy then let her weight go driving my cock deep up inside her. We both moaned loudly oh my god did that feel good!

"So deep!" She said again.

Leaning forward she braced her hands on my chest and started grinding her hips back and forth. Her head was down, her long hair tickling my chest. I couldn't see her face but could hear her making little noises every time she slid into me. I put my hands on her hips helping her slide back and forth. Megan pushed off my chest and sat straight up throwing her hair back as she did and using her legs began to lift herself up and down driving my cock in and out of her. My cock was straight up into her and every time she came down she gasped.

My sister wasn't the only one making noise this felt unbelievable never mind the fact that I could see my cock disappearing in and out of her wet pink pussy. Leaning back, Megan put her hands on the bed between my thighs, and arched backwards even more bending me at a different angle but one that felt even better as she resumed sliding back and forth. I moved my left hand from her hip and put my thumb on her clit again.

"Oh look at you taking care of your big sister!"

Megan began working her hips faster and I realized that at this angle I couldn't really use my hips to fuck her it was teasing the hell out of me knowing I'd have to wait for her to cum again before I could really fuck her. Turned out I didn't have to long to wait as Megan looked over at the bureau letting out a whimper of her own. The sight of us sent her into a frenzy of lust.

"Oh yeah look at you, you little whore; riding your little brothers cock breaking the rules!"

As she talked to herself Megan began riding me even harder. I have to say hearing her call herself a whore did it for me to; I began straining to pump her harder and whimpering with the need to cum. I kept my thumb moving the entire time however and reaching up with my right hand was able to just reach her nipple.

"Yes!" Megan exclaimed. "Oh yeah, you bad boy! Getting your nasty sister off while she rides your big fucking cock."She gasped then said;

"Twist it Mark, twist my nipple hard!"

I held back she had yelled at me last night for going to rough.

"I said twist my fucking nipple!" Megan snapped at me. Caught off guard I did as she said squeezing and twisting to the left.

"Fuck yeah!!" Megan cried out bucking wildly on my cock. I moaned as I felt myself not too far away. I could feel her pussy contract around my cock as she threw her head back and let out a long loud wail. Goddamn she was wild! Megan let herself go backwards unfolding her long legs so they were straight out her feet towards me This caused my cock to pop out of her pussy with a wet noise and I groaned;

"No please..." I started but Megan looked up at me;

"Get on your knees little brother."

I did right away kneeling between her long legs which she lifted up putting her feet on my shoulders.

"Go ahead Mark fuck the shit out of me!" She told me still out of breath from cumming.

Not needing to be told twice I leaned forward driving my cock deep into her. Megan cried out as I completely let loose pounding into her even harder than I had last night. We had been fucking for awhile now and I needed to cum so bad my balls were aching. Megan pushed her legs against me hard enough to lift her hips off the bed. My arms were behind her knees and I had her legs bent almost past her head. Megan was making little yelping noises with each thrust as I gave it to her even harder.

"Oh my fucking god Mark!" She cried out.

"Oh yeah!" I panted as I felt my cum building up and racing through my cock.

"Not inside!" Megan gasped out. "Pull it out and hold it so your sister can give you a treat!"

At the last moment I yanked my cock out squeezing it near the tip. Megan slid further down the bed and looking me in the eye said;

"Go ahead little brother shoot that hot cum all over your nasty sister! Anywhere you want just give it to me!"

Anywhere? I couldn't help myself, leaning forward on my right arm I pointed my cock right at her face and started jerking it. I gasped as the first powerful spurt shot out hitting her on the left side of her face covering her from forehead to chin. As I continued to stroke it Megan opened her mouth catching a good part of the second squirt on her lips and tongue.

"Oh yeah! Look at you cumming on your sisters face!" Megan said cum dripping out of her mouth. "Treating her like the slut she is! All of it little brother I want all of it!"

"Oh god!" I choked out as the next squirts caught her chin and neck the last few drops landing between her tits. When I finished I let myself go lying down on my stomach completely spent.

We both lied there panting. Until Megan said quietly;

"You bad boy look at what you did." I turned my head to look. "Ohh," I groaned as I saw my cum all over my sisters face. As I watched Megan licked her tongue around her lips catching some of it and bringing it into her mouth.

"MMMM." She turned to look at me smiling through the mess on her face.

"Not so bad being bad is it little brother?"

I laughed tiredly.

"Being bad feels pretty damn good."

Megan rolled over and picking up her shirt from last night wiped her face off then went into the bathroom. I sat up and looked at the clock, it was 9am. I had karate class at noon and Megan had to go to work at one. I was so tired I felt I could go back to sleep which would be an outright first for me. Megan came back in with a glass of water and after taking a few swallows passed it to me. I drank half and gave it back.

Megan put the glass on the nightstand and then pulling the sheet up lied down on her side.

"You gonna come back to sleep with me?" She asked. I laid down next her and put my arm around her waist. Megan made a happy little sound pushing herself up against me and I put my head down into her neck. We both sighed contentedly. No matter what I was going through this was where I always felt the best curled up with my sister who had now become my lover as well.

"Hey Mark?"

"What is it sis?" I asked, already feeling myself beginning to nod off.

"I'm glad you came looking for it this morning."

"Me too." I said with a laugh.

"No really little brother. I'm glad you wanted to be with me again."

"Are you crazy Why wouldn't I?" She shrugged.

"I don't know I thought maybe you really would think it was wrong."

I hugged her closer to me and whispered in her ear;

"You're the only thing that's ever felt right to me Megan."

"Really?"

She lifted her head and turned enough so I could see her. "You mean that?" She had tears in her eyes.

"Of course I do Megan I love you, you know that." She kissed me quickly on the lips.

"I do it's just nice to hear that you want me."

"I'll always want you Megan. Always."

"You know you can never tell anyone little brother. People would never understand."

"I know." I said quietly.

"But we don't care do we? We'll love like brother and sister but fuck like lovers. We can be the best of both worlds, and the best part is we'll be hiding in plain sight no one would ever suspect it. We'll be each other's dirty little secret."

"What about Krissy?" I asked voicing my one concern.

"What about her? You want her don't you?"

"Yeah but with us..." I trailed off.

"She'll never know Mark. You can have soft and sweet with your little Krissy then get it hard and dirty from you Nasty sister. Have her cake and eat mine too." She added with a laugh.

"And you're okay with that?"

"Listen little brother there's going to be three rules with us okay?"

"Rules?"

"Yes rules. First like I said we aren't for all the time I'm not saying we won't have a lot of fun but not every night got it?"

"Yeah." I said a little disappointed. I couldn't see not wanting this all the time.

"Second, and most important is that jealousy is an ugly emotion. There will be others for both of us Mark especially you. With your looks they'll all be after you, and pretty soon you'll realize that you can have them all, and I'm fine with that, but you need to be too If I'm with someone else. Remember I might have fun with them but I'll always love you best, and you'll be the only one that gets the best this Nasty girl has to give."

Megan stopped talking and after a couple of minutes I asked;

"What's the third one?"

Megan sighed then spoke quietly.

"Even though there will be others I want you to promise that there will always be time for me. That I'll always be your favorite because I already know you'll always be mine."

"Of course you will be! You're everything to me." I kissed her cheek and could feel tears on it.

"When you came here I promised you I would never let anything happen to you and I mean it. Please promise me you'll always be right here when I need you."

"I promise." I whispered hoarsely feeling myself choking up, Megan was the only one who could do this to me. "I'll never let anyone hurt you my sister ever."

"Same here little brother."

"Are you okay Megan?"

"I'm just fine little brother. Believe it or not I'm crying because I'm happy because now we really are everything to each other. You feel so good in every way, and trust me little brother this is just the beginning for us." She sighed contentedly. "Now let's go back to sleep were going to have a busy weekend being bad with each other."

I smiled at that thought and said;

"Sweet dreams my sexy big sister."

Megan giggled and whispered;

"Sweet dreams my naughty little brother. You're nasty big sister loves you."
