My name is Lucy and I’m a cheerleader at a state college. I’ve always thought of myself as a conservative girl. I had a normal childhood with a loving mom and dad, and a brother, Pete, who was 3 years younger than me. My sex life has so far been fairly tame. I’ve had 6 boyfriends, but have only had sex with 2 of them. I’m a petite girl, built for sex, but being a cock tease is just more fun for me. On rare occasions I’ll reward a guy with a BJ. But more often times than not, I’ll leave them rock hard and aggravated, to my warped enjoyment.

It is a miracle that I haven’t provoked anyone to the point of raping me. I stand 5’3 with curves in all the right places. My breasts are my best assets, a full 36 DD and I love showing them off with tight low-cut shirts. I have short powerful legs from cheerleading, to go with an amazingly tight little round ass. Lately though, I’ve been the one feeling frustrated.

My boyfriend Steve and I had just broken up. It was my first long term committed relationship. After 2 months of exploiting his sexual torment for my own selfish desires, I allowed him full access to my body. The sex was great for about a week, before becoming stale and uninspiring. Up to this point in my life, my pussy was pretty much off limits until I met Steve. I really liked him and having a boyfriend was fun, so I continued to stay with him for almost a year.

Eventually, I couldn’t ignore his inability to satisfy me anymore, so I ended it. He took it hard, breaking down right in front of me. Sexually frustrating a guy was something I took pleasure in, but actually breaking someones heart left me with a cloud of guilt that I couldn’t shake. After Steve, I decided to take a brake from guys.

6 months passed and I still wasn’t ready to start dating again. I was relieved when my mom called and insisted I come home for my brother Pete’s birthday. Being home would give me an opportunity to gather myself and snap me out of my funk. She told me that Pete was having a rough time as of late.

He was always a quiet boy, never really having many friends and never any girlfriends, which was a shame, because he’s one of the sweetest guys I’ve ever known and actually quite good looking. I tried on many occasions to introduce him to girls, but he was painfully shy. My girlfriends always gushed over his big brown eyes, but his awkwardness creeped them out.

I arrived at the house on Friday night. My parents were in the living room, and Pete was no where to be seen.

“Hey Lucy, welcome home, it’s good to see you.” My dad said, as he and mom got off the couch to give me a big hug.

“Are you eating ok honey? You look like you’ve put on a couple pounds.” My mom being critical, as usual. Actually, I was in the best shape of my life! I thought to myself.

“Where’s Pete?” I said, deflecting my moms comment.

My dad rolled his eyes, “He’s up in his room, like always. That boy is never going to get a girlfriend if he doesn’t get off that damned computer!”

I ran upstairs to say hello. I knocked on his door and walked in, which was a mistake. Barging in on a teenage boy was never a good idea. “Oh my god!” I cried out in shock.

I couldn’t believe what I saw. Pete was laying on his back, feverishly stroking the biggest cock I’d ever seen. I always thought my boyfriends were big, but Pete dwarfed them in comparison. “Pete, I’m so sorry!” I whispered as I slammed his door shut.

I went to my room and buried my face into my pillow. I’ve never felt so embarrassed. Pete, must be humiliated. Some help I’m going to be! I thought to myself bitterly.

I didn’t sleep much that night. I couldn’t stop thinking about Pete’s dick. How sick is that? He’s my little brother! I would fantasize about him, then scold myself, again and again. This went on for a couple hours, when finally, I gave in to my taboo thoughts and fingered myself. I was imaging how it would feel to have that raging piece of flesh fuck my tight little twat.

This was new to me. Until now, the thrill of the tease was what got me off. Maybe it was because of the 6 months without sexual urges? I bucked wildly as I brought myself to orgasm. Once I caught my breath and gathered my senses, guilt came over me. What’s wrong with me? I could never do that to my little brother. I just have to push this out of my mind, I told myself ashamedly.

The next morning I came downstairs. Breakfast was ready and on the table with everyone waiting. “There you are sleepy head. I almost sent Pete to wake you up.” Dad said over his morning paper.

My eyes darted over at Pete and I could feel my face getting flush. He was staring down at his eggs, as he uncomfortably adjusted himself in his seat. I let out a fake giggle and sat down. My mom came over and put the back of her hand on my forehead. “You okay dear? Your face is red.”

“I’m fine mom, thanks. So what do we have planned for the birthday boy?” I asked, changing the subject.

Pete, excitedly, broke his silence, “A couple of the guys are coming over to take me out tonight.”

My dad whispered to me, “They’re taking him to his first strip club.”

I looked over at Pete and he had a huge grin on his face. It’s been a long time since I’d seen him this excited. Mom shook her head in disappointment. She was worried about him. Especially after running across his porn collection on his computer.

Dad tried to ease her anxiety by telling her it was normal for a teenage boy to be curious, but he was beginning to worry himself. He’d tried talking to him, but Pete shuts down whenever the subject of girls is brought up.

After breakfast I pulled Pete aside. “Look Petey, about last night. It’s perfectly natural,”

Pete cuts me off. “Lucy, can we just forget about it?” He asks as he looks down in shame.

“No problem little brother, I guess that’s big brother now.” A flash of embarrassment hits me. Did I just make a reference to his penis?

“Yeah, I’m 18 today!” He said, as I give out a sigh of relief.

“Here’s you gift!” I hand him a $50 dollar online gift card.

“Thanks sis!” He gave me a little hug and sped off to his room. Sadly, I then realized that I had just contributed to his porn collection.

Later that day we all sat down and gave Pete his birthday cake. I could tell his excitement was just for show. All that was on his mind was tonight’s activities. It was going to be the first time he’d seen a woman nude, that is a real life girl, not on a computer monitor. His shyness wouldn’t be a problem, they were going to come to him. This could be a good thing I assured myself. Maybe this will give him the confidence he needs to interact socially.

That night my parents went out. They were having a date night. My mom needed to be distracted from the fact that her baby boy was out at a strip club. Dad knew that she’d be pacing all night until he came home.

Pete was anxiously pacing, while waiting on his friends. When they finally honked from the driveway he nearly knocked me down as he flew out the door. I changed into myPJ’s and turned on theTV. Nothing was on. After flipping around for about 20 min I got bored. I started wandering what kind of porn Pete had on his computer. Was it soft core? Or maybe something really sick that I couldn’t even imagine. My innocent little brother looking at porn! It was hard to believe.

Curiosity was getting the better of me. I went to his room and turned on his computer. I was surprised to find that he had no password and that his porn was on his desktop. Pete had quite an extensive collection. As I was scrolling through it I came across a folder named Lucy. My heart skipped a beat. I felt a knot in my stomach. I was afraid at what I’d find, but I opened it anyway. There were pictures of porn stars in cheerleading outfits. Was he imaging me in these pics? I’ve never caught him checking me out, was he attracted to me? My question was answered when I came across one with my face photoshopped to it.

At first it creeped out, then I actually felt flattered. She even had a similar body. Just then I heard the front door open. I quickly shut down the computer and ran off to my room. I heard crying from the hallway, then a door slam. It was Pete! Something must have gone wrong. I crept down the hall to his room and lightly tapped on the door.

“Petey, is everything ok?”

“No! Just leave me alone!” He cried.

“Pete, please talk to me. You’re my brother and if something is wrong I want to help you.”

A couple seconds later Pete opened his door. His eyes were red and puffy, tears rolling down his cheeks. “I was in such a hurry, I forgot my I.D,” he sobbed. “They wouldn’t let me in and the guys just left me outside. They laughed at me and called me a freak! I had to walk home!”

“Oh Pete, I’m so sorry.” I gave him a big hug.

The hug lasted longer than most I’d given him. Hugging my brother is usually an awkward moment; a light touch and a couple of light pats on the back before he pulls away quickly. This time was different. He needed to feel connected to someone, but the connection he really needed was one a sister couldn’t give him.

I felt that I had to do something though. His 18th birthday was a disaster and his depression was going to get worse. Tonight was a night he had been looking forward to for a long time. What if I gave him a little show? I knew from his computer that he’s already fantasized about me, why not give him the real thing? It would be harmless, I assured myself. Maybe even fun? No, I told myself, Pete would die from embarrassment if I had even suggested it.

We pulled apart and I was shocked to notice he was looking down at my tits! I was in such a rush getting out of his room, I hadn’t noticed that my top was only buttoned halfway up. My PJ’s were already a snug fit, but when we hugged, my breasts had been pushed up and trapped, leaving my bountiful cleavage exposed. I raised an eyebrow and smirked as I noticed his eyes were still transfixed on my bursting PJ top.

“Pete it’s time for me to give you your birthday present!” I said putting my hands on my hips and pushing my chest out, daring my voluptuous DD’s from busting out of my stressed and straining shirt.

He swallowed hard and looked down at the floor. “But you already gave me a present.” He said sheepishly.

“That wasn’t your real present silly! Give me 5 minutes, then come to my room.” I said as I dashed down the hall.

What am I doing? I questioned myself as I rifled through my closet for a cheerleading outfit. He’s my brother, this is so wrong! If mom and dad find out…..I’m just going to give him a little show, that’s it! Perfectly harmless, well not perfectly. There it is! My uniform from high school. I wore this before I got my busty figure.

I quickly stripped out of my PJ’s and squeezed into my uniform. My skirt fit alright, but it was shorter than I remember. It barely covered my ass, but maybe it had always been that way? The top wasn’t going to fit if I wore a bra. It didn’t matter I guess. I wasn’t actually going to take my top off. Hopefully it won’t rip open during my performance. There was a knock on my door. He’s early!

“Just a second!” I yelled, as I took one last look in the mirror and put my hair in a ponytail for one last touch.

I noticed my nipples were protruding through my braless top, leaving little to the imagination. I can’t believe I used to fit into this uniform! I was feeling nervous on my way to the door. “Okay, close your eyes birthday boy.” I whispered softly as I opened the door.

“What is this Lucy?” He asked as I led him to a chair.

“Shhh, now keep your eyes closed and sit.” I ordered. “If you open your eyes you don’t get your present.”

I stood behind the chair and whispered, “Ok Pete. Tonight I don’t want you to think of me as your sister. I’m just a girl, who wants to show you a good time. No one will ever know about this. If this sounds too weird for you, I will understand. You don’t have to say anything, just let out a cough if you want me to continue.”

Pete let out a cough and adjusted himself in his chair. He’s into this! Now I’m having second thoughts. This is wrong, so wrong! Then I remind myself that as twisted as this seems, my brother needs this.

“A couple ground rules first. Number one, no touching. Keep your hands at your sides at all times. Number two, this has to be a secret. If mom and dad find out, I would be in big trouble. And finally, I’m only going to dance for 1 song, that’s as far as it goes. Are we agreed?”

Pete let’s out another cough and I could tell he was hiding a smile. My second thoughts had disappeared, I was now getting excited! I bit my lip as I noticed a bulge in Pete’s pants. Am I ready to do this? I asked myself nervously as I took a deep breath. I looked back down to his lap and grinned.

“Ok Pete, open your eyes.” I ordered seductively as the music started.

“This is a gift you’ll never forget!” I promised as I started to dance.

His face turned beet red as he gazed at me from head to toe. Pete adjusted himself again trying to hide his very noticeable bulge. His hungry eyes watched me as I thrust my hips and jiggled my breasts.

I started imagining what it would feel like to experience a dick that size. It had to be at lease 12 inches! No, no, no! I have to keep these dark thoughts out of my head! I warned myself. Pete let out a gasp as I tugged at my shirt. Does he think I’m really going to show him my bare tits? Nudity wasn’t the plan, but the more I turned him on, the less I felt in control of my inhibitions. I’ve flashed complete strangers before, why not my brother?

“You really want to see this little brother?” I asked in my sexiest voice.

“Yes.” He answered quietly, trying to mask his enthusiasm.

Should I just tease him? Or give him the show he really wants to see? This was the point of no return. My heart felt like it was going to pound out of my chest as I slowly pulled my shirt over my head. “Happy Birthday little brother!” My tits bounced around as they were finally released and allowed to hang freely. “Happy Birthday to you!” I sung using my best Marilyn Monroe impression.

Pete muttered, “Awesome!” As he swallowed hard and adjusted himself in his seat again, still failing to hide the monster trapped in his pants.

I know I should have felt a little weird about it, but I didn’t! I felt a rush come over me and I unconsciously licked my lips as I saw his penis twitch. He must be miserable having it so constricted in his jeans, I thought. His hands fidgeted as I slowly sauntered towards him. He was fighting himself to keep his hands down at his sides. I stood in front of him and ran my hands through his hair as my breasts dangled an inch from his face. He was in agony, and I loved it!

A set of perfect tits right in front of him and he can’t touch them. I could now feel his breath on my nipples as his breathing got heavier. I circled around his chair with my hands still in his hair and I jerked his head back. I continued to torment him a little more, swaying my supple bosoms teasingly before finally rubbing them in his face. I felt his tongue flicking around searching for my nipples. “Bad boy!” I scolded him. “No touching includes tongues!”

“Head forward!” I commanded.

He snapped his head back to front. God, I couldn’t believe how turned on I was! My panties were soaked! I felt alive again! The song was almost over. How much more was I willing to do? Without another thought I reached down under my skirt and slipped off my panties with one hand while the other reached over his shoulder and messaged his chest. I waded them up and shoved them in his mouth. Pete let out a groan and his nostrils flared as his breathing intensified.

I couldn’t stand it anymore, his thick prick was almost taunting me as I noticed it twitch again. I circled back around to the front and straddled his leg where his straining cock was pulsating through his pants. His jaw dropped in bewilderment as my pussy lips surrounded the shape of his cock. Pete grunted as I gave him a couple of slow thrusts. Suddenly, Pete doubled over and knocked me to the floor.

Too much! I thought, reprimanding myself. What have I done? This isn’t just some dumb guy I’m toying with, it’s my own brother!

“Oh, shit!” He cried out in embarrassment.

He got so worked up, that he came in his pants! Pete tore off his shirt to cover the mess in his lap. For someone who never worked out, he actually had a decent body. Decent enough to get a girlfriend.

“I’m such a fuck up!” He yelled at himself.

“It’s okay.” I comforted him.

“Pete, I’m so sorry! How can I make this right?” I asked, hoping I could salvage this night.

He sat there silently for a few seconds then asked bashfully, “Maybe you could let me touch you a little?”

“Pete!” I screamed, as I covered my naked breasts with my hands. “I knew this was a bad idea! Brothers and sisters don’t do this kind of thing!”

I felt like a hypocrite as the words came out of my mouth.

“No, you’re right, I’m sorry! I just don’t have any experience with girls, and you are so, uh, so, uh, beautiful.”

I looked into his eyes welling up with tears and felt bad for what I had done. My heart went out to him. Pete was so sweet and innocent, and I just humiliated him. I had to do something to make him feel better! Before I could even think about the consequences, I walked over to him and pulled his hands to my breasts and brought my lips to his.

Our tongues darted in and out of each others mouths. Pete had soft lips and was a surprisingly good kisser. I was getting more and more turned on as his hands explored my body. As he made his way down to my skirt, I came to my senses and pushed him away. “Pete, I’m sorry, I’ve taken this too far! I don’t think it’s a good idea that we continue.”

“Why?” He questioned.

“Because I am your sister and this is wrong! I’m afraid where this will lead us!” I answered sternly.

“Is there anything I could do to you?” He asked fumbling his words. “Maybe, I could use my tongue? To give you, uh.” He looked down at the floor, too shy to look me in the eyes, or finish his request.

I was mortified at the reality of the situation. I made my little brother hot for me! Then all of a sudden a fire lit in my stomach. The forbidden nature of this was turning me on in a way I had never imagined. Oral sex isn’t really sex is it? I thought to myself, trying to justify my growing incestuous desires. As long as I don’t allow any penetration, we won’t be crossing the line.

Besides, I was itching to be satisfied! This could turn out to be valuable practice for future girlfriends, I thought further justifying my carnal lust.

“Alright Pete, I will let you go down on me.” I said, shocked at the words that were coming out of my own mouth. “But that is it! After this, we are done! Remember we are brother and sister after all.”

“Okay!” He agreed, as his face lit up.

I got up and let my skirt fall to the floor. I was now completely exposed in front of my brother. He sat there with his mouth open in amazement.

“This is it Pete! I mean it! We are done after this.” I reminded him.

I laid back onto the bed and spread my legs, revealing my glistening slit.

“Wow, you’re shaved just like the girls in the movies!” He raved, as he stared captivated at his first glimpse of a nude vagina.

I could feel his hot breath on my now sopping wet pussy. He was savoring the moment. “It’s like a blossoming flower!” He described.

“Yes little brother. A flower you can eat!” I cooed growing impatient, as my bald vagina eagerly awaited some attention.

The anticipation was driving me wild! I let out a little whimper as his tongue parted my lips and worked its way to my clitoris. His tongue swirled and danced as I moaned like a cat in heat.

The boy had done his homework! All those porn movies had payed off. I pulled his shy hands up to my breasts.

“Play with my nipples, but not too hard.” I instructed.

As he worked my pussy like a pro, one of his hands found its way down to where the action was. I knew what he was doing. As much as my pulsing cunt was begging for his probing finger, I had to stop his advances. “No Pete! No fingering. Penetration of any kind is too far!” I warned.

Too far? This had already gone too far, but we can’t go down that road. I won’t allow it! Pete reached back up and continued to fondle my heaving breasts as he flicked his tongue around my swollen clit. I couldn’t believe it! This was the best oral I’ve ever had! After 5 minutes of unbelievable pleasure I felt an orgasm building up inside me.

“Oh fuck! I’m going to cum!” I wailed as I thrashed around.

As I came, he pulled on my nipples with brute force. My nipples are really sensitive. I usually don’t let guys get too rough with them, but Pete’s violation of my tits intensified my orgasm to the point that I thought I was going to pass out. I couldn’t believe how bold he was becoming.

“Oh fuck! Oh fuck! Oh fuck!” I repeated as I had multiple orgasms. A first for me!

“Okay, okay! I can’t take anymore!” I cried out as I pulled his head up by his hair. My juices were dripping from his chin as he smiled.

“How’d I do sis?” He asked excitedly.

“Not bad little brother!” I responded trying to catch my breath. “But my nipples are so sore! I thought you were trying to pull them off!”

He apologized, “Sorry sis. I guess I got carried away.”

“No problem.” I returned. “It actually felt really good!”

“What now?” He asked with a sly smile.

My body was still shaking from the tongue lashing I had just received, but I was still in control. “Oh, no! We’ve already done too much little brother! We can’t get reckless!” I quickly sat up and covered myself with a pillow, as the guilt returned.

“I’m sorry Lucy, I’m just so, um, so,” His shyness stops him and he puts his hands over his face in frustration.

My guilt disappeared when I looked down and saw that familiar bulge in his jeans. I kept telling myself no, but I then felt myself begin to cave! It’s only fair that I return the favor, I reasoned with my conscience.

“Alright Pete.” I said reluctantly. “I will give you a BJ, but I won’t let you finish in my mouth. That is something I just won’t allow. I’m serious! I’m drawing a line here! Deal?”

“Deal!” He returned quickly, as he stripped off his jeans.

I shuddered at the thought of finally seeing this hunk of meat up close. He pulled down his boxers to reveal his manhood in all it’s glory. It was even bigger than I realized! I tried not to look too eager. “Lay down on the bed.” I ordered.

He laid back, as his rock hard prick hovered over his stomach. I’ve never imagined a cock this big! The tip of his head reached his belly button. The size was overwhelming! I gently ran my finger nails from his balls to his head, as he squirmed in anticipation.

“You know little brother, god gave you a gift.” I told him, trying to build up some much needed male ego. “This is the biggest dick I’ve ever seen! You’re gonna make some lucky girl very happy someday.”

“Really? But all the guys in my videos seem to be the same size or bigger. I thought I was just average?”

“No, you have something really special here.” I assured him.

Pete’s cock flexed wildly as I ran my tongue up his shaft to his expectant tip. He gasped as I wrapped my lips around his head. There was no way I could even take half of this thing in my mouth, so I concentrated on his head and gently stroked him.

My little fingers could barely reach around the thickness of his throbbing shaft as I began pumping him faster and faster. I looked up and saw Pete watching in amazement as I bobbed up and down on his dick. My nipples were being tickled as my breasts swayed back and forth across his stomach.

Pete’s breathing was beginning to quicken. I knew he was getting close. It’s too soon, I thought. I was having too much fun!

I stopped and sat up. “I’m not ready for you to come yet Pete.” My desires were getting the better of me now.

He looked confused, almost frustrated. “Okay.” He conceded.

He started to sit up and I pushed him back down. “We can’t have sex.” I paused, biting my bottom lip. “But I just have to feel this beast on my pussy!”

“Holy shit!” He let out excitedly.

I straddled him bareback, my moist lips enveloping his veiny fleshy rod. Pete let out a deep moan, as he pulled his head up to watch. I then slowly began to glide my wet pussy along his shaft. Oh my god! I thought to myself. How could something this wrong feel so good!

We were both breathing heavily as I continued faster and faster. I did my best not to get too close to his head. I didn’t want temptation to get the better of either of us. More so than it had already!

Pete had reached around and had both his hands on my ass as I rode his shaft like a cowgirl. That familiar feeling began to swell up inside of me. I was about to have another orgasm!

“Oh, yes!” I screamed as my head shot back and my chest heaved out.

Pete squeezed my tits, gentler this time, as I came on his dick. I collapsed on his chest, quivering as he rubbed my back helping me to catch my breath.

“Lucy, I’m about to lose it. I feel like my head is going to explode!”

“Sorry, Pete. Do you want me to finish what I started?” I asked, realizing what a dumb question that was.

“Can we try something else?” He asked curiously.

“My rule still stands Pete!” I reminded him. “No penetration!”

“No, no, let me uh, put my penis, um, between, uh.”

He’s afraid to say it, so I said it for him. “You want to titty fuck me?”

Pete’s reluctance to say dirty things to me was turning me on even more. “Do you want to cum on your sisters tits?” I asked with a devilish grin.

He sat there speechless as he gazed at my luscious mounds. I inhaled deep and began twisting my upper body causing my breasts to jiggle. “Yes, oh god yes!” He cried out.

I giggled as I laid on my back. Pete mounted me and I pushed my breasts together as he slid his pussy soaked cock between them.

As he pumped away at my tits I gave him a little reward with my wet full lips every time his tip reached my mouth. I could tell he was going nuts, when all of a sudden he stopped.

Confused, I asked, “Whats wrong Pete?”

“Look Sis, I know after I finish, that is it. I really appreciate what you’ve done for me tonight, I really do, but.”

“But what?” I was almost afraid to ask.

“I’m 18 years old and I still don’t know what a, a,”

“I know where you are going with this Pete, and I’m sorry we just can’t!” I reminded him.

“Just for a second!” He begged. “I have to know how it feels!”

He looked so eager and still so innocent! I started to feel myself waver. “How about if I just let you stick a finger in?” I tried compromising.

“That would be great, but I’m sure its not going to be the same?” He countered.

He was right, but could I really allow my brother to do this? Just a quick feel could easily turn dangerous, I warned myself. Pete’s innocence and curiosity, however, was effecting my judgment. My little brother appeared to have a power over me that other guys hadn’t.

“Okay Pete, but just for a second, and you can’t put it all the way in! Just the head. This is just so you can see what it feels like. You gotta promise me!”

“Yes, I promise!” Pete assured me, enthusiastically.

“You have to wear a condom if we are going to do this!” I added. “You do have condoms? Don’t you?”

Pete’s face turned pale and he let out a disappointed sigh. “I’ve never had a reason to.” He admitted ashamedly.

He was crushed, and it was breaking my heart! Being the conservative girl I was, I’ve never had an unprotected penis inside of me.

As I imagined Pete’s naked flesh trespass through my tight opening, I could feel my vaginal muscles contracting. I shook my head and tried to come to my senses.

“Look, Pete.” I tried reasoning. “Even with a condom, I shouldn’t have ever considered taking it this far. I’m sorry!”

Pete pleaded, “Please Lucy! I gotta know what it feels like! Just for a second, please!”

Pete was in agony. I couldn’t believe it, but I was actually going to let him do this! I’m disappointed in myself for letting it get this far, but I can trust him. He’ll stop when I tell him to. Pete was too sweet and kind to force himself on a girl, especially his sister.

“Alright Petey.” I relented. “But remember, in and out. That’s it.”

Without saying a word Pete leaned down and gave me a deep open mouth kiss, while I gave his cock a light stroking. He then kissed his way down to my legs where I opened up spread eagle. I could tell his anticipation was at a fever pitch. He rested the head of his cock on my stomach.

“Just real quick Pete.” I reminded him softly.

Pete pulled his penis down to my swollen pussy. After all of my orgasms, it was aching for a dick! Stay strong I thought to myself. My head felt woozy, and my stomach had butterflies. I felt like a virgin again as fear and excitement overwhelmed me. But still, I can’t let this get out of control!

His tip was at the entrance and he began rubbing it up and down, parting my moist pussy lips. Wow, he is so big! I thought, wondering if I could even take something this size had we gone all they way.

“This feels so amazing!” He whispered.

“Go ahead Pete.” I gave permission. “Remember, just the head, then pull it out.” I reminded him softly.

He positioned himself to my opening, then leaned forward until he was hovering over me with his hands at my sides holding himself up. I could tell he was scared. His breathing almost seem to reach the point of hyperventilation.

“It’s okay Pete.” I whispered as I ran my finger tips across his chest trying to calm him down.

I looked down and could see his engorged penis eagerly waiting. I was feeling nervous myself. His raging hormones were about to be put to the ultimate test. Would he be able to restrain himself after sampling my forbidden fruit? I wasn’t so sure anymore. I placed my hands on his hips as a precaution.

“Lucy!” He yelled out, as his anxious cock slid through my inviting lips and into my hungry pussy.

I let out a deep gasp as I felt the pressure of his enormous pulsing head inside of me.

“Are you ok sis?” He asked concerned.

“Yes.” I whimpered.

“It’s so warm and slippery. This feels better than I imagined!” He cooed, as I felt him slip in a little more.

“Pete, that’s enough, now pull out!” I ordered nervously through deep breathes.

“Lucy, you gotta let me push it in a little more!” He begged.

“Absolutely not Pete!” I yelled. “You promised me! You have to take it out now!”

“Doesn’t this feel good though?” He pleaded.

Pete’s teenage hormones were taking over and I knew I was in trouble.

“This is wrong little brother! It’s incest! Besides, I’m not on the pill! You could get me pregnant!” I yelled at the top of my lungs.

My mind knew it was wrong, but my body was beginning to betray me. He only had the tip of his penis inside of me and I could have pushed him off, but I hadn’t. My lustful urges were taking control.

Pete began to notice this as well. The words coming out of my mouth were different than how my body was acting. I began rocking my hips, almost daring him to go all the way. I could feel him slowly slipping deeper.

“No Petey!” I screamed desperately. “Please, please don’t do it!”

Pete had only went in a couple inches, before he began to pull out. I felt a brief moment of relief thinking it was over. “No, no, no!” I whined, as he then began to push it in again, this time deeper.

My arms began to shake and my hands turned white as I struggled to keep him from entering me fully.

I yelled out, “Petey please no! I’m your sister! You can’t do this! Besides, you are too big. It won’t fit! You’re going to hurt me!” I was honestly afraid he would rip me in half!

My pleas were falling on deaf ears. He continued to push in and pull out slowly going deeper and deeper each time, stretching my tight little pussy to its limit. I wasn’t feeling as much pain as I thought I might.

It actually started to feel good! Better than good, it was euphoric! The forbidden passion I felt having my brothers cock inside of me was intoxicating! The war waging between my conscience and my lust was over. Lust had overcome me. I couldn’t resist it anymore. I dropped my hands from his hips, surrendering myself to him.

“Do it Petey!” I conceded. “Fuck me! Fuck your slutty sister!”

“Okay!” He gasped as he began to slowly and rhythmically work his way deeper.

“Just don’t come inside me! Okay?” I begged.

“Oh, oh, ok, okay.” Pete stuttered as his cock continued to explore my tight crevice.

I looked down in awe as I watched all 12 inches disappear inside of me. I squealed like a virgin as he ran me through, balls deep. I couldn’t believe I was able to take every inch of him! The pain quickly turned to pleasure as his thrusting intensified. My tits danced around helplessly from the jarring my pussy was taking.

Then fear struck me. What if he cums inside of me? This could be disastrous! I haven’t been on the pill for 6 months! He said he wouldn’t, but I can’t trust him anymore. Pete had taken control and I was at his mercy!

“Petey, when you’re ready to come, you can do it in my mouth.” I pleaded, giving him an incentive to pull out.

My brother, was fucking me like a stallion and I was howling in ecstasy. We had hit our stride. His dick was was now gliding through me like a hot knife through warm butter. All of a sudden I heard the front door close. Panic hit me like a bolt of lightning!

“Petey! Mom and dad are home!” I whispered, frightened out of my mind.

Pete didn’t stop, he was in a trance. This was the greatest moment of his life and he was in another world. I heard footsteps and voices in the hallway. I tried pushing my legs together and bucking him off, but to no avail.

“Petey!” I whispered desperately as I squirmed beneath him. “We gotta stop! Mom and dad are outside the door!”

I tried my best not make noise, but I couldn’t help my huffing and puffing as Pete pounded me ravenously. Plus, the bed was squeaking and the head board was slamming against the wall. There was a knock on the door and I pleaded with him, “Pete please we’re gonna get caught!”

“Lucy, what the hell is going on in there?” My father demanded.

He knew what was going on. The loud breathing, the squeaking bed springs, and the unmistakable sound of wet flesh on flesh. The door knob rattled furiously.

Luckily I had a lock, but it wouldn’t keep them out for long. I was still trying to quiet my breathing, but my brothers 12 inches of throbbing flesh plunging in and out of my pussy just wouldn’t allow it.

“Is Petey in there too?” I heard my mom ask my dad frantically. “What’s going on in there?”

My dad was banging violently on the door as he screamed our full christian names.

Pete began to groan as he began to pump away even faster! He was completely unaware of what was happening. Oh shit! I realized. He was going to cum inside of me! Not only are my parents going to find us having sex, but my little brother was going to impregnate me!

Then something strange happened. All of my fear and panic washed away. My parents screams fell of into the background.

For that fleeting moment I was experiencing the most erotic pleasure I’d ever felt. My animal instincts had taken over. I returned my legs to the spread eagle position and I cried out “Fuck me brother, fuck me!”

Peter started fucking me faster and harder until he reached a frenzied pace. The head board sounded as if it was going to smash through the wall. My parents must have been screaming on the other side of the door, but I could no longer hear them.

Pete’s glorious cock had my full and undivided attention. We continued to fuck like beasts, oblivious to the immediate danger that awaited us. “Oh, fuck Petey!” I cried out as I began to climax. “I’m going to cum!”

I arched my back and shuddered as a I came. “Petey!” I screamed. “I can’t take much more!”

My brother kept fucking away like a crazed dog as orgasms hit me in waves. Each time I came it was more intense than the last! Finally I could feel Pete’s penis swell up and pulse inside of me. He was about to cum! “Go ahead Petey! Cum inside your sister!” I screamed.

Pete cried out, “Lucy! Lucy!”

His body tensed up as he shot load after load of his hot seed deep inside me. My gripping snatch milked his sweet nectar as his fucking slowed to a stop. Just when Pete finally withdrew his spent flexing cock, reality crashed down on both of us as our enraged father kicked open the door.

Mom and dad stood in the door way speechless, with a look of horror on their faces. Pete’s now flaccid member was flopping around helplessly, while he urgently searched for cover. And I was frozen in fear. My trembling legs were still spread wide open, as the most damning evidence of this immoral act was oozing from my red throbbing pussy.
