About 2 weeks ago I saw my 16-year-old brother Marc and his girlfriend Lisa . . . doing stuff.  They were in his room.  She was underneath him.  He was naked and was moving up and down on her, and she was moaning really loud.  I saw her fingers digging into his back as he humped her.  Ever since then I’ve had . . . well, weird feelings about Marc.  Like wanting to see him naked in the front.  I’ve even wanted to . . . to touch his dick.

They broke up shortly after that, so he’s been home more often.  Today he came home from practice early, so my parents weren’t home.  We’ve been around each other in underwear a lot of times, so when he showered and came into the family room wearing only his boxers, it was no big deal.  Well, normally it wouldn’t have been.  He sat down next to me on the small sofa.  I handed him the remote which surprised him.  “Wow! Thanks Chelle.”  I cuddled up against his bare chest and stared down at his boxers.  The fabric in the front was open a bit, and I so badly wanted to see what it looked like.  My heart was pounding pretty fast!  

After a while I noticed his breathing was different.  I looked up and saw he had fallen asleep.  Very carefully I took my fingers and opened his boxers.  I looked around and could see some of his dick.  I really wanted to touch it badly!  When he started snoring I decided to make my move.  I slowly slid my fingers into his boxers and felt his dick which was surrounded by a bunch of hairs that were very different from the kind on his head.  It was more like his arms and legs but thicker.  His dick was really soft and felt smooth.  I picked it up and moved it outside the hole in his boxers to look at it better.  Marc stirred but did not wake.  I ran my finger along the smooth skin to the tip of it and then rubbed the tip.

I loved how it felt!  As I continued using my finger to feel all over it, including a big vein, it started to grow and get hard.  As it grew, I continued stroking it with my fingers.  I knew guys got hard-ons, but of course I had never felt one before.  I’m only 12!  It got big and hard really quick.  I moved my finger along the tip where there was a hole.  I figured that’s probably where the pee came from.

“You want to feel my balls, too?” Marc’s voice asked softly.

I jumped.

“Shhhh.  It’s OK, Chelle.  That actually feels really good.”

I looked up at him and suddenly noticed how deep blue his eyes are.  “You wanna feel ‘em?”

I nodded my head.

He smiled and I felt heat.  “One thing, though.  You have to promise me we don’t tell anyone about whatever happens here, okay?  That’s REALLY important.”

“I promise,” I said.

“Atta girl.”  I watched him lift his hips up and slide his boxers down.  His dick was standing straight up.  “Be gentle with them.  They’re really sensitive.”

I gently felt them.  They were kind of fun to play with.

He slipped his hand under my shirt and began rubbing my back.  “You like them?”

I nodded him head but moved my hand back to his hard dick.

“That feels so good, Chelle.”  After a few moments I felt him lift my shirt up.  I let him remove it.  “We’re gonna have some real fun, Chelle.” I felt his hand move to my tit and rub my nipple.  I was bigger than some girls at school, but nothing like Lisa!  “Why don’t you pull my boxers off.”

I moved off the sofa, grabbed the boxers and slid them down his legs and then off.  Okay, I know it may sound gross, but . . . well, he looked hot!  He sat up, grabbed me by the waist and pulled me between his hairy legs.  I watched his face move to my chest, and his blue eyes started up at me as he began sucking on my tit.  His hand was suddenly rubbing my groin.  

“Since you’ve touched my dick, do I get to feel your puddin’?”

I nodded my head briskly.

He took hold of the waistband of my shorts and panties and then slid them down.  I shivered as his hands slid down my skin.  I stepped out of them.  He fingered the area around my pussy as he watched me.  My eyes closed and my mouth opened.  “You like that?” he asked.

I bit my lower lip as his finger ran around the opening to my pussy and nodded my head.  I moaned as I felt his finger slowly sink into it.   

“Oh yeah! So nice and tight!”  His face grew closer to mine, and I felt his lips on mine.  I had heard about frenching and hoped he would do that now.  I wasn’t disappointed!  His tongue entered my mouth and I kissed him back as his finger slid inside me deeper.

He stopped kissing me and pulled his finger out.  He sat back and said “I want to feel your mouth on my dick, okay?”
I stepped between his legs and knelt down so I could get my mouth on his cock.  I put it in my mouth, and he sighed “Oh that feels good!”  I went down on him more, and he cringed a bit.  “But not with your teeth!  No teeth, Chelle.”  I opened my mouth wider and decided to kind of pull my lips over my teeth a bit as my mouth went down his dick.  “Oh yeah! That’s it, Chelle.  Suck my dick, Sis!”

I started doing it a bit faster, and I felt his hand on my head nudging me down a bit.  After a few moments he told me to get next to him on the couch.  I released his dick and positioned myself how he had told me to.  As soon as my mouth was back on his yummy dick, I felt his hand on my head again.  Then his other hand slid down my back, slid over my butt, and then I felt his finger spreading me open again.  His finger slid into me and started moving back and forth.  

He let me continued sucking him as he fingered my pussy for a while.  Then he stopped me and told me to get the lotion out of the bathroom.  I brought it to him and watched him spread lotion on his dick.  “Won’t that taste nasty?” I asked.

He smiled at me and said “Well, there’s more to do with a dick than suck on it, even though that felt so damn good.”  He slouched on the sofa more and motioned for me to step between his legs again.  He pulled my shoulders toward him.  When I was close, his lips closed on my nipples again.  After he sucked on them for a few seconds, he sat back against the cushion.  He pulled me toward him again.  He pulled my shoulders so that my upper body leaned down.  His dick ground against the mound of my groin as his tongue invaded my mouth.  

He stopped kissing me and looked deep into my eyes very seriously.  He fingered my nipples as he said “Now remember, we don’t tell ANYONE about this.  Not our parents, not your best friend, even someone who promises you anything and swears on a stack of Bibles they’ll never tell.”

I nodded my head vigorously and said “Okay, Marc.  I swear I won’t!”

“Climb up here,” he said.  I climbed up so I was kind of in his lap, but my legs were outside his.  “Now sit down a bit.”  I slowly sat down as his hand moved between my legs.  Then I noticed he had grabbed his dick and was holding it as my pussy moved closer to it.  “Oh fucking yes!” he said as I felt his cock begin to enter me.

It kinda hurt as I lowered myself onto his dick more.  

“Ohmigawd, Chelle!  So fucking tight!”

I couldn’t really lower myself more right then, so I kind of moved my hips around to see if that would help it feel less painful.  His hands rested on my ass.  I opened my eyes and saw his head resting against the cushion.  He was panting.  I leaned forward and kissed him on the chin.  His eyes opened, and he smiled at me.  He moved forward and thrust his tongue into my mouth.

I wanted to feel more of his dick inside me, so I lowered down again.  I ignored the burning sensation as his hard flesh slid deeper.

He moaned loudly and asked “You gonna take that whole dick, baby?”

“Yes!” I almost cried out.

“You’re so fucking hot, Chelle!  You almost got your big brother all the way inside you.”

“Yes! Oh yes!”

His hips started moving up and down.  

“Ride my dick, baby!  Ride it!”

I wasn’t sure what he meant, but I imagined the time we had gone horse riding.  So I started bumping up and down like I was in the saddle.

“Goddamn!  That’s right, Chelle!”  He was thrusting up as I rode him.  “Come on, baby.  Take it all the way!”

I took a deep breath and let my weight push me down all the way.  I ignored the pain.  He was bucking upward, and I leaned back and braced my hands against his knees as he fucked my faster.  His fingers dug into my hips as he picked up speed.  I pushed my pelvis closer to him to make sure every bit of his cock was in me.  I felt pressure building rapidly.

“Mmhmm!  Chelle loves that dick, don’t you?”

“Yes!  I want it, Marc.  I want it!”  I rode it harder and then suddenly cried out as . . . I don’t know, something fantastic rushed through me making me almost scream, but I definitely made a noise I can’t even begin to spell.

“Oh fuck yeah!” he said and picked up speed even more.  Then suddenly he yelled “Fuck!” and stopped moving.  Everything except for his dick which was twitching in my puddin’.  He pulled me to his chest and wrapped his arms around me.  As his dick moved inside me again, I reflexively tightened my pussy muscles, and I felt his dick twitch harder.

I felt more relaxed and satisfied than I ever had before, and I completely relaxed against him, fully aware his dick was still inside me.  Really, I didn’t want him to ever take it out again!  

After a while I felt him kiss the top of my head.  I turned my gaze upward, and he kissed my forehead.  “Did you like that?” he asked.

“Fuck yes!” I said quoting him.

He chuckled.  “So. . . you think you might like to have fun again?”

I nodded my head quickly as if I was agreeing to the absolutely most incredible thing on the earth. 
“You don’t know how happy I am to hear that!”

I put my head on his chest again.  I couldn’t feel his dick all that well anymore, but I didn’t want to move.  After a while he looked at his watch and said Mom and Dad would be home soon.

As I got up to get dressed, I remembered my concert.  “Marc,” I began hesitantly.

He was lifting his boxers off the carpet.  “Yeah?”

“I have a band concert tonight.  Would. . . would you go?”

He smiled at me widely and said “Of course!”

Then I spotted red stuff on his dick.  “What’s that?” I asked pointing.

He looked down and at first seemed shocked and then calm.  “Oh, that makes sense.  I popped your cherry!”

“My cherry?”

“Yeah.  You were a virgin until I fucked you.  Girls sometimes bleed the first time they’re fucked.”

“Yuck!”

He laughed.  “It’s normal.”

Then the phone rang.  It was Mom.  She said we needed to be dressed and ready to go when she got home.  I told Marc.  He pulled up his boxers, and we walked to our rooms.  I got dressed in a black skirt and white blouse which was our concert uniform.  He came out wearing tight jeans and a tight T-shirt that showed off his muscles way too nicely.  He saw me appraising him and smiled knowingly. 

He came up to me, took my hand, and placed it on his groin.  “Just think what will be waiting for you tonight.”

“Really?” I asked excitedly.

“Yeah.  Mom and Dad are going to a party tonight after your concert.  It will be just you and me, Chelle.”

I felt my mouth split in a grin that spread from ear to ear.

He moved in close to me, pushing his body against me.  “Think you can keep up with me tonight, Chelle?”

“Why wouldn’t I?”

He put his hand down the front of my blouse and rubbed my tit.  “Because I plan on coming in you at least twice tonight.  Once in your mouth and once in your tight, hot pussy.”

“Why only twice?”

He laughed heartily at that.  “Let’s just see what happens.”

It was hard being around him waiting for our parents.  I just wanted to have him naked and inside me!  The car ride wasn’t any better.  He kept teasing me!  We were in the back seat, and I’d feel his hand ride up my thigh.  Once or twice he even put his hand under my skirt and rubbed my vi-jay-jay through my panties.  He quit when I almost moaned.

The concert and ride back seemed to take forever, too!  When we got home, we went into the kitchen for a snack and to get something to drink.  Mom and Dad poked their head in and said goodnight and that they’d be home late.  

Marc handed me a soda and got something else out of the fridge.  I grabbed the counter and lifted myself up to sit and watch him while he cut a couple of pieces of cake.  He broke off small pieces and fed them to me with his fingers.  I laughed in between bites.  My laughter stopped when I saw him pull off his shirt and toss it.  He moved between my legs, and I felt his hands under my skirt.

“So, little sister, is that pussy of yours ready for some big brother dick?” he asked and he began sucking on the side of my neck.  His fingers found my panties and pulled them down and then off.

“Yes!  Oh yes Marc!”

He withdrew his hands from my skirt and unbuttoned my blouse.  He pushed it open and ran his thumbs over my nipples.  He pushed it off my shoulders and pulled my head to his chest.  I sucked on his nipples.  He pulled away, spread my legs apart further and lifted my skirt up.  I watched his head lower and felt his lips on my thighs.  He sucked the skin there lightly which drove me wild, and then I felt him kissing up higher.

I was breathing harder as his lips traveled closer to my groin.  Then I felt his fingers spreading apart my lips. . . well, you know, THOSE lips.  Then his tongue was licking my pussy!  I leaned back and thrust my hips up as his tongue probed me.

“Oh gawd! Oh gawd!  Fuck me, Marc!  I want your dick!  Put it in me!”

He licked me faster.

“Please! Fuck me now!” I yelled.

He moved from between my legs and scooped me up.  With long strides we quickly arrived in the living room.  He set me down, and I reached forward and grabbed the buttons on his jeans and unfastened them.  Immediately I saw the dark brown of his pubes.  “No underwear!”

“Why waste time?” he asked.
I yanked his jeans down, and he stepped out of them.  He grabbed my head and pulled it to his dick.  I opened my mouth and began sucking his cock hungrily.

He pulled away and pushed me down onto the couch.  As I lay down, I swiveled my legs up onto the couch.  He grabbed a small plastic thing out of his jeans pocket, opened it, and squirted it on his dick.  While he did that I quickly stripped off my skirt.

He climbed onto the couch and asked, “Do you like me, Chelle?”

“You’re my brother! Of course I like you.”

He sucked on my breasts.  “No, do you LIKE me like me.”

I shivered as his tongue worked my nipples.  “Fuck yes!  You’re so hot!”

When his dick pressed against my groin, I spread my legs apart.  His hand guided his dick into my pussy, and then he entered me.  He was able to get his dick inside me easier, and he started moving it back and forth several times before shoving it all the way in.  He adjusted his pelvis and started using longer strokes.  I lifted my legs and kind of wrapped them around him before I let out a loud “Fuck me!”
