Forbidden Temptation

I turned around to face my brother and said, "Kevin, I was worried and..."

I trailed off as my mind sort of went blank when I saw him. He was standing in the bathroom with his jean zipper open and an absolutely massive cock sticking out with his hand around it. It was incredibly long and plenty thick too. Was that thing real? I had been with plenty of guys, but I had never seen a cock anywhere close to that size. It felt big through his jeans, but I had no idea it was that fucking huge.

For a long moment, neither of us said anything as we were both too shocked. In a normal situation, I was sure a regular person would have immediately freaked out and left. Instead, I just stared helplessly at his giant dick. My heart started to pound hard against my chest and I felt my pussy begin to dampen. Was I seriously getting turned on right now? This was my little brother's cock, this was wrong! But goddamn did I want to touch it.

"Emma, what are you...what the hell are you doing here?" I heard him say.

"I...uhh..." I stammered out as I continued to stare at his impressive dick.

Eventually, I saw Kevin move towards me but my eyes never left his goliath cock. Why wasn't he putting it away? In just a few steps, he stood right in front of me and removed his hand from his cock while it throbbed and pointed right at my face. It was like my hand had a mind of its own as it reached out to feel it. There was no harm in touching it right? It was just innocent exploration after all. My fingers brushed up against it and I felt how hot it was.

My heart pounded so hard and I felt so warm that I started to feel lightheaded. I needed to leave before I completely lost myself in the moment. I needed to go somewhere quiet so I could regain control over myself. I slowly removed my hand, placed the key on the bathroom countertop, and quickly walked out of the bathroom. While I made my way down the hallway, I ignored everyone and everything as I worked my way to the staircase upstairs.

People knew that the party host, Alex, didn't like guests being upstairs, so it was empty and quiet. I opened the door to one of the rooms and saw it was a small library and study that was dimly lit by a few lamps.

Once I walked in, I half-closed the door behind me and went over to a tall bookcase. I reached out to grab one of the shelves to steady myself and I breathed heavily. So many thoughts went through my mind, but the one I kept going back to was how hard his dick felt. God, what the hell was wrong with you Emma? You acted like he was some hung hot guy you just met at the party, not your fucking brother.

While I winced in frustration, I heard the door to the library open and close. I turned around and saw my brother standing inside the room as he locked the door. The moment I saw him, my heart started to pound even faster and I even felt my nipples harden under the dress. Goddammit, why did he have to look so fucking handsome in that outfit? Why did he have to be so fucking ripped and hung too underneath those clothes?

"Look Kevin, I'm sor--" I started to say exasperated.

"You know Emma, I'm not inexperienced like you think. I've been with plenty of girls, especially when word of my big cock got around," he said calmly and deeply while he undid the top button of his shirt.

I stood there completely stunned. What was happening right now?

"What are y--" I tried to reply.

"I've been with the hottest girls at my school," he said almost arrogantly as he started to confidently walk towards me while undoing yet another button.

"Ok, serio--."

"I've been with teachers, and I even fucked some of your friends after they begged me long enough," he said with a knowing smile while his hands undid half the buttons of his shirt at this point.

My eyes widened in surprise. Was he fucking serious? Those fucking sluts. No wonder I found some of them whispering with my brother when they visited me. How the hell were they able to keep it a secret from me? My budding anger was soon forgotten as I caught glimpses of his ripped muscles through his open shirt. I was such a sucker for muscular guys it was no wonder I became a cheerleader so I could be around them. I slowly rubbed my legs together and felt my pussy start to become wet.

"You should know that I've fucked half of the varsity cheerleading squad too," I heard him say as he undid the last button which fully exposed his torso.

He soon stood right in front of me and outstretched one of his arms and pressed it against the bookcase right near my head. He gave off a powerful aura of confidence that I found incredibly alluring. My eyes felt trapped by his gaze and I couldn't help but gulp as his powerful and tall body loomed over me. Fuck, not only was he ripped and confident, but he was tall too.

"But none of them are even close to how hot and sexy my sister is. You're the one I always fantasized about," he said authentically while he smiled down at me.

"Kevin...this is crazy. We should just leave," I said barely above a whisper in a shaky tone while my eyes trailed down to look at his muscular chest.

Part of me sincerely meant what I said, but I didn't do anything to follow through on it. I was caught up looking at his perfectly sculpted body. His pecs jutted out far from his body and they practically begged to be explored. Not just that, but his abs practically screamed for attention too.

I saw his free hand move out of the corner of my eye as it grabbed one of mine and forcibly pressed it against his chiseled body. My hand lingered for a moment and felt just how hard his muscles were and how hot his skin was. It was incredible. However, I knew this was wrong and quickly moved my hand away. I was about to say something to stop this insanity when he grabbed my hand again and firmly kept it against his muscular body.

I slowly looked back up at his face and I felt him forcibly move my hand over his chest muscles and then down to his abs. The way he just took charge turned me on more than I cared to admit to myself. My legs shook slightly and I breathed in hard. What were you doing Emma! This can't happen! This shouldn't happen! You need to find a way to leave!

I gazed up into his hazel eyes and felt so powerless. I saw my brother lower his head and a moment later, his soft lips pressed up against mine. I wanted to stay still and not move my lips. I meant to shove him away or slap him to snap him out of it. Instead, I lost myself in his tender kiss. His lips tasted like honey and I couldn't resist tasting them. Before I knew it, my mouth opened and we sucked on each other's lips.

This was forbidden and completely taboo. I knew it. Yet, I still couldn't stop myself. I wanted this. I wanted this so badly. My body felt so alive and I felt so turned on that I couldn't bring myself to stop it. How did something so wrong feel so damn good? My head started to get dizzy from the whirlwind of thoughts, but I was steadied when my brother released my hand and wrapped his arm around my waist, and pulled me into him.

Feeling his hard body pressed up against mine made me delirious with desire to explore it further. I brought my other hand to his chest and squeezed the hard muscles of his pecs. It wasn't long before I lowered them and ribbed them along his impressive eight-pack. The more I explored the body, the more passionately I kissed him.

I slowly raised my hands while my fingers traced the crevices of his abs before they reached up to his shoulders. They grabbed onto the collar of his shirt and I started to pull it down his arms. He lowered his arms to help as I gently pulled it lower and lower until his shirt slipped off his body. I softly touched his ripped arms while my fingers grazed over his sculpted biceps and his triceps too. I loved how strong and hard they felt.

While I explored his muscles, I felt his biggest muscle press against my stomach. His cock felt rock hard and seemed to desperately strain against his dark jeans. I was eager to see it again. I didn't care that it was my brother's cock, not anymore. I needed to see it once more and explore every inch of it.

My hands soon left his arms and lowered to his waist where I started to unbuckle his belt. Kevin broke our kiss and I felt his hands reach for his waist and assisted me in pulling his pants down and over his humongous cock.

Once I saw his giant dick bounce directly in front of me, I sucked in my breath at the sight. My little brother was blessed with a huge rod that most girls would drool over and he knew it. My hands instinctively reached for it and this time I wrapped my fingers around his shaft. My eyes widened slightly when my fingers were barely able to close around it. Fuck, he was thick as well as long. I looked back up into his eyes as I bit my lip and started to softly stroke his dick with both of my hands.

"Never seen a 9-inch cock before huh?" I heard him say with a smile before he leaned closer to me and whispered in my ear, "Get on your knees and worship it like the slut sister you are."

I glared at him in defiance but my body betrayed me and I felt myself slowly squat down. It was like I wasn't even in complete control of my body. It knew what I wanted, no, needed more than I did. Soon my knees reached the floor and his gigantic cock was now directly in front of my face. I opened my mouth and slowly lowered it onto his bulbous cock-head while my hands moved to pull my hair behind my ears. I made sure to gently rub my soft lips on it as it entered my hot and wet mouth and my tongue slid underneath.

He was so freakin' huge. I had a hard time keeping my mouth open large enough to fit him inside. I was no stranger to giving guys head, but I never had this big of a challenge before. I was determined to give him the best blowjob he's ever had and put my slutty friends to shame. Don't worry little brother, your big sister will take care of you.

Once my mouth got used to his size, I swirled my tongue around his cock-head and started to bob my mouth up and down his dick. My hands moved back to his dick and slowly pumped the bottom of his shaft to ensure that I didn't ignore any part of his cock. It felt so hot to the touch and was perfectly rigid. I was already obsessed with his massive tool.

I slowly lowered my mouth further and further down his shaft as I took more and more of his cock into my mouth. It wasn't long before he hit the back of my throat and I suppressed my gag reflex. There was no way I was stopping now. I was sure none of those other sluts he'd been with was ever able to deep-throat him and I was committed to being the first.

I released my grip around his cock and squeezed his muscular thighs as my mouth slowly swallowed more and more of his dick. I wasn't sure if I was able to fit his last few inches in but with a final push I was able to fit his entire length inside and I removed my mouth off his cock and breathed heavily.

"Fuck Emma, no one has ever sucked my entire length before," I heard him say in a sigh of pleasure.

I knew it. I beamed in pride and looked up and smiled at him while my hands went back to his cock and spread my residual saliva all over his rod. I was about to suck him hard again when I saw him reach down and he roughly pulled me up onto my feet. In a split second, he turned me around and pressed me against the bookcase.

"I can't wait any longer, I gotta fuck this tight body of yours," I heard him say roughly.

His hands went to the bottom of my dress and with a strong tug, he pulled it up and over my toned ass. His fingers caressed the smooth skin of my butt before they lowered and his fingers slid on the wet skin of my inner thighs before sliding up and down my soaked slit.

"Damn Emma, you're dripping wet! Even your thighs are drenched. Seems like you're already craving my big cock," I heard Kevin say with a tinge of amusement.

"Fuck you, Kevin. Just fuck me....oh God....please," I said intending to sound in control, but I was sure I sounded desperate instead.

I felt him reposition behind me and I felt his mighty cock slide along my pussy lips. I couldn't help but moan slightly at the sensation and I felt my entire body quiver. Just a moment later, I felt his giant cock-head split my pussy lips and start to slide into my hot tunnel. Usually, guys would have to spend a little while coaxing my tight hole to open wide enough, but I was so primed and wet that his massive cock immediately slipped in. I moaned loudly and deeply.

He felt large in my mouth but he felt even bigger entering my tight pussy. I instinctively raised myself on my toes as I felt him push inch after inch of his incredible dick into me. My pussy walls clenched tightly around his shaft, but he seemed to still easily slide further in. Several times I thought that he finally shoved his entire length inside me, but each time I was surprised that there was still more of his meaty cock. Fuck, could I even fit his entire length?

Just when I thought I couldn't take anymore, I felt his pelvis push up against my firm ass and I knew his cock was now fully buried into me. I leaned my head back as my eyes rolled in the back of my head from feeling completely stuffed. I never had a cock this deep into me before and my pussy walls continued to greedily squeeze his shaft. I felt him slide his dick out slowly before pushing it back in gently. I smiled at first before a long moan escaped my lips. I felt the tenderness and love in my brother's movements. It was like he didn't want to hurt me with his incredible tool.

How did this happen? How did we even get here? Not long ago I was scheming to stop him from coming to the party and now I just begged him to fuck me. Instead of seducing one of the Avengers, I was taking my own brother's goliath cock. I never considered myself a slut before, but after this, I had to. I honestly didn't care as long as I got to feel like this.

It wasn't long before he started to speed up his thrusts. I moaned louder and louder the harder he pounded his cock into my tight hole. He seemed to get the message as he began to shove his herculean cock into me roughly and at full force. I knew my pussy was creaming all over his mega cock and I gripped the bookcase hard. No dick had ever satisfied me this much before.

While he continued to pound me, I felt his hands move as they reached in front of me and squeezed my breasts through the dress. I knew he could feel my hardened nipples through the dress. I reached one hand up to the back of my neck and untied the dress string there. The top of my dress immediately started to fall and once Kevin moved his hands, my entire upper body was now naked. His hands eagerly returned to my now exposed breasts and squeezed them hard. Fuck, he was so strong. I loved it.

His fingers seemed like they couldn't ignore my rock-hard nipples. He started to flick them between his fingers and I felt my moans only get louder. My nipples were always sensitive, but today they felt incredibly raw and tender. Electric jolts of pleasure were spreading throughout my body from my nipples and I felt my body shudder in response. I felt a powerful orgasm building inside me and if my little brother continued what he was doing I knew I would explode in pleasure.

He switched up his assault on my nipples by now softly pinching both between his finger and this thumb and gently pulled them outward. I was confused at first, but then he increased the power of his thrusts even more. As my perky breasts bounced from the force, my nipples were repeatedly pulled too. I never experienced anything like this before and I rewarded him with a deep, guttural moan.

My body was hot before, but now it felt like a volcano on the verge of eruption. My entire body started to quiver as a powerful orgasm began to crest. My hands let go of the bookcase and rested on top of Kevin's hands to keep them on my breasts as my body started to shake. My pussy repeatedly convulsed around my brother's thick cock and it caused him to pause his thrusts while he left it buried deep inside me. My mind went blank from the pleasure and I opened my mouth wide but the pleasure was too much for me to even moan.

I arched my back and wrapped my hands around the back of his neck while I breathed heavily and started to come down from my orgasm. I took some deep shuddering breaths while I hung onto him tightly. My body spasmed a few additional times and every spasm brought new waves of pleasure as his fingers still clenched my nipples tightly.

Once I felt I had full control over my body, I felt him slip his massive cock out of my pussy. His hands then left my breasts and went to the sides of my dress as he began to roughly pull it down my body until it fell to the floor at my feet. I turned around and saw that he kicked off his shoes and slid his jeans off his legs as well. His large hands soon grabbed my waist and he pulled me into him and kissed me passionately on the lips. I wrapped my arms and his back and my hands felt how muscular and strong his back felt too.

I was beginning to lose myself in his soft lips when I felt his hands grab my ass and he quickly picked me up off my feet. He did so seemingly effortlessly and I had to say it was a huge turn-on to be carried this easily. My nude heels slipped off my feet as he turned us around and headed to a desk nearby. He gently lowered me until my bare ass touched the cool wood of the table. We broke our kiss as I leaned back on the mostly empty desk and rested my upper body on my elbows.

I now had a full view of his naked body and he looked magnificent. His skin was sweaty from the exertion, but it simply made his body shiny and more enticing. I swore his muscles looked even more defined while I saw him breathe heavily in front of me. More impressive still was his rock-hard dick that pointed straight-up in the air and showed no signs of being tired. I spread my legs widely and looked at him with a face that screamed 'please fuck me hard'.

He grabbed his titanic dick and slapped it hard on my pussy. I groaned in response and he did it again which caused me to moan even louder. Taking a step forward, he raised his cock and dropped it on my tight and toned stomach. It felt so hard and heavy, but my eyes once again widened at the size. Holy shit, how did I fit that thing inside me? It looked like it went clear into my stomach.

I looked up at him and bit my lip while I started to grind my pelvis slightly as a clear sign that I wanted him inside me. I felt like a total slut. However, for a body and a dick like my brothers, I would be happy to be a slut for him.

It wasn't long before he angled his cock and pointed it straight at my pussy. He pushed his hips forward and his humongous cock-head easily split open my pussy lips and slid inside. I let out a soft moan as my eyes were fixated on his man meat. I watched as inch after inch disappeared inside me while my hands squeezed my perky breasts softly. I don't know why, but I loved watching his mammoth lance impale me while I felt my pussy squeeze his cock tightly.

Soon his entire length was shoved inside and I dropped my head back while I moaned loudly. His hands grabbed my waist and he squeezed tightly as he pistoned his cock in and out of me quickly. Each powerful thrust brought a new moan out of me. He was pounding my body so hard that I felt the desk below us creak and shudder while my body was slowly getting pushed back. I laid down flat on my back as I reached my arms above my head and gripped the opposite end of the desk with both of my hands to stay on top of it.

Before, my brother seemed in control and calculated with his movements. Now though, he seemed to fully give in to his animalistic instincts and roughly slammed his body and cock into me. I loved that he lost all control. It felt so hot and carnal that we were both lost in our own lust. My body felt so taut like it was trying to not explode in sheer pleasure. His cock was so thick and long that it was repeatedly hitting a spot so sensitive and so deep within me that I knew that I was going to explode in another orgasm soon.
