Sharing Big Bro’s Monster Cock With My Bestie

Becca seduces her faithful best friend into trying her brother’s monster cock

“B-Becca, please… Stop..!”

I had my lips wrapped around her sensitive little clit, swirling and sucking and teasing. My fingers were knuckle deep inside her tight pussy and Talia’s hips buckled against me every time the pads of my fingertips teased that spongy spot inside her.

Her mouth begged me to stop, but her hand said otherwise, twisting into my hair and pulling my face hard against her core. God, she tasted so damn good. Musky and sweet as a clean teenage pussy should.

Korean pop music played in the background. Loud enough to mask her moans as her parents were downstairs, but not so loud that I could hear her sweet whimpers.

“I’m so sorry, Ben,” she cried out, clamping my face tight between her fleshy thighs.

Her nails dug into my scalp and she closed her hand over her mouth, struggling to contain her cries as she climaxed.

I chuckled, relishing in the effect I had on her and savouring her sweet nectar as I dragged my tongue over her cunt.

Talia shuddered and pulsed a few more times before she collapsed against her bed.

I climbed up to join her, cuddling her.

Her forearm covered her eyes, as if it could hide her from what had just happened.

“That was insane.”

“But so fun,” I purred.

Post climax clarity was a bummer. Our naked bodies pressed against each other and I gently caressed one of her huge breasts. Her not pushing my hand away was a good sign, even if she was feeling the guilt churning in her gut.

“I’m a terrible person,” she murmured.

“If it helps, it was me who seduced you.”

“What should I say to Ben?”

“If it was me, nothing. Besides, most guys don’t consider it cheating if their girlfriend plays with another girl.”

“You think so?”

“I know so. It’s a huge male fantasy. It’s different when it’s with another man. Hits different. Like an ego thing.”

Talia considered that for a few moments.

“This is definitely a fantasy come true for me, amongst many others.”

“What else have you done?”

“What haven’t I done?” I said, smirking. One thing that drawn me to the curvy beauty in front of me was how inexperienced she was. We’re similarly aged, both twenty. Whereas I was sexually experienced, Talia was relatively pure. Untainted. She was dating Ben for a few months and it didn’t seem like he was exactly showing her the time of her life in the bedroom.

If she did, she wouldn’t be craving the way I made her cum.

A smile spread across my face at the thought. Her sweetness tingled in my mouth.

“Can you tell me other things you tried?”

“I’m happy to. I enjoyed being tied up, spanked, degraded, free use, CNC… I could go on for ages.”

“I don’t know half the things you mentioned.”

“I had a great guy showing me, helping me learn that side of myself.”

I could see in her eyes she was curious. The way her eyes sparkled like a guiding star. The underlying curiosity under that mask of innocence that I used to guide her into bed with me.

“Do I know him?” she asked.

“Yeah. But I can’t tell you who it is.”

We cuddled, and I waited. The stereo barely finished playing halfway of a K-Pop song before she pounced.

“I need to know. The curiosity is killing me.”

I gave a meaningful pause. I was going to tell her, but I was still nervous about doing so.

“Swear you won’t tell anyone?”

“Cross my heart.”

“Well… It’s my big bro.”

“Seriously?”

“Yep.”

“But that’s your brother. I mean, that’s-“

“Yes I know.”

“How did that even happen?”

“I suppose there was always an attraction on both sides. We were drinking, chilling out one night and lines were crossed. And it’s been that way ever since.”

“That’s mad.”

I smiled, and we listened to a few songs.

“I suppose it’s kinda hot. I wouldn’t wanna do anything with my own family, but I can see how the taboo aspect of it makes it so hot.”

“I agree,” I said, leaning in and giving her a kiss. Talia moaned as I cupped her pussy, delighted how soaked she was.

“Did you like the thought of my brother fucking me?” I whispered into her ear.

“Yes…” she moaned as I slipped a finger into her pussy.

“Would you like to see that? I’m sure I can arrange it.”

“W-what? N-no I… But what about Ben?”

I delved another finger into her cunt, pumping my fingers in and out of her.

“There’s nothing to worry about,” I purred. My heart pounded as she rocked her hips, feeling her edging close to another climax. “You can just watch. You won’t have to do anything you don’t want to.”

My fingers were a blur now. I played with her enough to know how hard I should go to draw that climax out of her.

“You’re going to make me cum again!” she cried. B-Becca!”

My friend shuddered and rocked as I embraced her. I savoured the feeling of the inner walls of her pussy tightening around my invading fingers.

She fell back onto the mattress for the second time.

“I need to go,” I said, after she was sufficiently recovered.

“Why?”

“I am really horny, and I need to cum or it’s going to stress me out all night.”

“I have toys her if you want.”

I grinned. After Talia’s head cleared from her orgasm, guilt would invariably take over. That was why she hadn’t offered to get me off.

“I’m okay, thanks. I need cock. And there’s nothing like a nice big fat one waiting for me back at home.”

“Is he… There right now?”

“Maybe, maybe not. But we have an open door policy. As long as we’re discreet, we agreed we can fuck each other whenever we feel like it.”

Talia swallowed. No doubt she liked the idea of free use.

I put my clothes back on and gave her a peck on the cheek. “Have a think about my offer, okay?”

She nodded meekly.

***

It didn’t take long. A few days later, Talia texted me, asking if we could ‘study’ over mine. I told her everyone was out Wednesday evening so that would be ideal.

She came over, looking as nervous as a girl going on her first date. I told her my brother wasn’t home for another hour – he was at the gym, and we got comfortable with some drinks. We even had textbooks out on the coffee table in my living room just to make the lie more believable.

We joked and giggled, and the wine really helped loosen Talia up.

“I know what you’re here for, but I want to make sure there’s absolutely no pressure, okay?”

Talia nodded. “Okay.”

“Have you dressed up for Ben yet?”

“No.”

“No naughty school girls or slutty outfits for him?”

“No.”

“He ever asked you to dress up for him?”

“No.”

I bit my tongue. That guy didn’t sound very fun in the bedroom. “Hmm, well, I have an idea. Let me show you what Jonah bought me the other day.”

“Your brother buys you stuff?”

“Of course! He gets off on me sending him selfies in them. Couple of times he’d send a photo or video back of him jerking off at work. So hot.”

Talia’s face flushed.

I excused myself for a moment, went upstairs and brought down a box. I opened it up in front of her, revealing a pink lace babydoll, complete with matching crotchless panties.

“Oh my,” Talia said, holding up the flimsy garment. “This looks very risque.”

“It’s so fun. You wanna see?”

“I don’t mind.”

“Good. Then strip.”

“I thought you were going to wear it to show me.”

“Heh. Nah, it’s more fun if I see you in it instead. C’mon, it’ll look great on you.”

She flustered as I undressed her, clearly not used to wearing such clothes. But fucking hell, it looked amazing on her.

The outfit was for me, after all, and it was several sizes too small for Talia. Her huge breasts struggled to stay inside the thin fabric, making her look even more erotic. I loved how her pussy was exposed when she stood in front of me.

“I look like a freak.”

“Nonsense, you look absolutely fantastic.” I cupped her breasts, feeling her nipples harden against my touch. “I know you’re here to watch me and my brother play, but I want some fun with you, too. Come here.”

I guided her down to the sofa and disappeared between her legs. After seeing how slutty and innocent she looked, there was no way I wasn’t getting a taste of that cunt.

I lapped along her puffy slit, drawing her sweet nectar along my tongue. She moaned and whimpered and cursed softly as her body.

And that was how Jonah found us when he walked in.

“Damn, that’s a sight to see.”

Talia tried to shrivel away, her arms instantly covering her breasts. She wanted to run away and hide, but I held her in place with a steady hand. “It’s okay. Jonah knows the rules.”

“Don’t worry about me. Becca is getting all my attention today,” Jonah added, pulling his top off and exposing his hard, muscled body.

A slight pang of jealousy coursed through me as Talia’s eyes lingered on his body.

“Bit rude to stop, sis,” Jonah grunted as he came up behind me. I chuckled and dived back between Talia’s legs and lapped at her pussy. Sweet stifled moans escaped her lips as I teased her clit and speared her hole with my tongue. She was still a little uptight, but when my hands found hers, I pulled them away from her breasts.

“Talia, you’re fucking gorgeous,” Jonah said behind me. His hands disappeared under my skirt and found my panties, and he peeled off of me.

It was hard focusing on my friend’s pussy and also aching for my brother’s cock. I heard his belt buckle unclasp and him shuffling his jeans down.

A loud, audible gasp from Talia was all I needed to hear. I smiled to myself while drawing in her scent.

“It’s…” she whimpered.

“Is it bigger than your boyfriend’s?” I heard Jonah ask.

“Y-yes…”

My fucking brother. He loved an ego boost as much as sex itself. I reached back with my hand until I felt his cock, and couldn’t help but sigh with glee. Thick, girthy and throbbing with need. I guided to my entrance and his tip pushed into me right away, making me moan into my friend’s cunt.

I glanced up and Talia was wide eyed, watching for real that I was indeed being fucked by my own brother.

“Fuck, you always feel so wet and tight for me,” Jonah grunted as his hands gripped my hips.

“You got my body well trained,” I moaned, feeling my brain fog with bliss as his cock filled me.

My brother didn’t waste a moment, lifting his hand and driving it down hard on my buttocks.

“Fuck,” I groaned, savouring that sharp, sweet pain.

“You like that, don’t you, my naughty little slut sister? Shall we see what happens if I force it all the way inside you at once?”

“No, wait- “

Jonah thrusted his hips forward and gave out a low animal grunt. God, I loved that sound. So feral and primitive. But at that singular moment I couldn’t focus much on anything other than his fat cock completely filling me, stretch the inner walls of my pussy to the limit.

Usually he’d take his time, because he wouldn’t want to hurt me like that. But Jonah knew me too well. He knew how fucking excited I was for it, for his cock to be buried deep inside me like this.

“Oh fuck!” I cried out. One big thrust was all it took to push me over the edge. My body tightened as a white hot explosion bloomed from my core and radiated through my body. I screamed against my friend’s wet cunt, watching her as she watched me climax all over my own brother’s cock.

“Heh. You liked that, don’t you?” Jonah said, grinning. “You liked it more being watched by Talia. Watching you enjoy your brother’s cock.”

He thrusted his hips, making his cock stimulate me further.

“Y-yes,” I cried out weakly.

“I’m no where near done with you. Now be a good little slut and make sure you treat our guest right.”

I felt Jonah’s hand on the back of my head, forcing my mouth over Talia’s pussy. She whimpered as I snaked my tongue out, obeying my demanding brother.

It was hard to concentrate on licking and sucking Talia’s pussy with Jonah’s cock plunging in and out of me, though.

The thick sweet scent of my best friend’s nectar, coupled with my brother’s cock driving in and out of me again, made me cum a second time.

It was hopeless. Jonah had boundless stamina, and I couldn’t ignore Talia.

As my brother continued to fucking me, I slid my finger inside Talia. She was so silky and wet. She was heavenly. By the time I had two fingers inside her, she was in the thick of it, humping my fingers and curling her fingers into my hair, grabbing my head and forcing my mouth back over her clit.

Talia gave into her inhibitions, drunk on the pleasure, drunk from being watched by my brother.

It was rather exciting having someone bear witness to the taboo union I shared with my own brother. Especially when it was a girl as innocent as Talia.

“Fuck,” Jonah grunted. “I swear your pussy is tighter than usual. You like being watched, don’t you?”

“Y-yeah,” I admitted.

“You’ll be glad to know I’m going to cum soon. Where do you want it?”

A shudder coursed through me, causing the inner walls of my pussy to tighten around my brother’s shaft. He let out a chuckle.

He slammed his cock harder into me. “I said, where do you want it?”

“You know where,” I cried out.

“I want to hear you say it. I want your pretty friend to hear what a nasty little slut you are.”

“I-in me,” I whimpered. “I want your cum inside me, big brother.”

“Fuck yeah, let’s cum together. I’ll do that thing you love.” He drew up a gob of spit and drawn out a long rope of saliva, letting it land on my asshole.

My eyes went wide. “No, wait..!”

Too late. Jonah amped up his thrusts, which made my mind go blank with bliss.

And then he jammed his thumb into my tight little asshole. Spit wasn’t as slippery as lube, but it gave just the right balance of friction that triggered all those nerve endings by the entrance of my puckered hole.

“Oh, God!!!” I yelped. My body spasmed violently as another orgasm coursed through me. Somehow, my hands found Talia’s and our fingers intertwined. Our eyes met, and it was as if she was gazing deep into my soul.

She was watching my expression with awe. Watching the face I made as I came from my brother’s cock.

“Fuck, take it, you dirty little slut,” Jonah growled.

Another desperate cry escaped my lips as I felt my brother’s cock swell up inside me.

“T-Talia…” I moaned out.

“It’s okay, Becca. Let it go. It’s fine.”

Her hand reached out and stroked my hair as I continued to ride the waves. I relished in the feeling of helplessness as my brother’s hands dug in at my hips, not letting me go until he finished emptying his thick load deep inside me.

God, I loved that feeling. So full and complete. My womb was his to fertilise…

Jonah pumped his hips once, then once more, making sure every drop of his cum was emptied out inside me. He slowly withdrew, making me gasp as the feeling of emptiness replaced the feeling of being so stretched.

Jonah gave my ass a playful slap and held his dick in his hand. It was softening but still looked big and thick.

“Fuck me, I needed that.”

He walked around the bed until he stood beside Talia.

“You want to help me clean this up?” he asked, giving his cock a casual jiggle.

Talia looked around, but her eyes were mainly glued to my bro’s dick. “I can’t see a towel,” she mumbled.

“We don’t need a towel, just use your mouth,” he said, grinning.

His dick was inches away from Talia’s face. But she didn’t pull away.

“I-I have a boyfriend…”

“Yeah? Is he as big as me?”

“No, he isn’t,” she admitted.

“Can’t knock him too hard. Not many guys are my size. But christ, look at it. It’s covered in my sister’s juices. I would love for you to help me with it.”

“I… I dunno…”

He inched closer. Any closer and his tip would bump against her nose. I swallowed as I watched her nostrils flaring, drawing in the mixed scent of my pussy juices and my brother’s cum slathered all over his dick.

He reached out, gently placing it on Talia’s head.

“It’s just helping out, Talia. Why don’t you just try it? You can stop if you want.”

He didn’t wait for an answer. He tugged and his cock slid against her lips, smearing her with our juices. Talia opened her mouth and moaned. She didn’t push away, though.

“Are you good at sucking cock?” I asked her.

“I don’t know,” she breathed.

“Well, here’s your chance. Think of it as practice to be better at making Ben feel good.”

I watched as the lust glazed over in her eyes. I knew the all too familiar desire when being offered my brother’s amazing cock.

“I suppose that makes sense,” she said.

With that, she opened wider and let her tongue out, tentatively pressing it against Jonah’s shaft.

To his credit, he wasn’t being pushy. He just stood there are my best friend explored his cock for the first time, running the tip of her tongue along his shaft, feeling the ridges and thick veins along the side. It wasn’t long since he came, but his cock was hardening again from her touch.

“How’s the taste?” Jonah asked.

Talia moaned. “Its so musky and sweet…”

“Do you like it?”

She nodded.

“I’m glad. Now come here, sis. You’re not shirking off your cleaning duties.”

I smiled and joined Talia. We were like two naughty little sluts cleaning my brother’s cock with our tongues. He had a hand on each of us, caressing us lovingly as we worked. It wasn’t long before he was fully erect and pulsed against our lips.

“Do you want to try cleaning the tip?” I asked my friend. It was my favourite thing to do. Copious amounts of precum leaked out of my brother’s tip and ran down the underside. One time, we were chilling on the sofa as he played on his PlayStation and I was just there, casually teasing and kissing his hard on. He rewarded me with a good fucking after.

I smiled as Talia moved over until her lips were pressed over Jonah’s tip. It took some effort to get her mouth to take in his tip. She had a look of determination burning in her eyes, though. Our shy little Talia wanted to prove she could take his cock.

“That’s it, good girl,” Jonah grunted.

She moaned, and I watched my brother’s face scrunch. I watched as her nostrils flared and saliva and precum seeped out from the corners of her mouth. Fuck, it was so messy and hot.

I couldn’t help but reach under and cup her pussy, feeling how hot and soaked she was.

“Mmph!” Talia cried around Jonah’s cock as I circled her clit with my finger.

“Thank you, Talia,” Jonah said. “You got my cock nice and clean.”

He carefully eased his tip out of her mouth and she gasped for air.

“But I got somewhere else for you to clean,” he added.

He got her to lie down flat on the sofa.

“Go on, you know how I like your pussy nice and clean,” he said to me.

I nodded and knew what he wanted.

I climbed on top of Talia and lowered my pussy over her face. Talia whimpered, but the moment my cunt rested over her mouth, I felt a moan against me and her tongue darted out, lapping up my cum filled pussy.

I stifled a moan and furrowed my brows. It was the first time I had my cream filled pussy eaten out. My hands gripped her thighs, and I watched my bro casually stroke his rock hard erection.
“Don’t forget her, too.”

I reached down and started stroking my friend’s inflamed lips. My fingers glistened with how excited she was.

God, it was such a strange feeling. I felt so exposed and turned on at the same time. I loved how Talia’s tongue was greedily lapping up my brother’s cum out of my pussy.

I was glad my fingernails were sanded down. I eased my fingers in and out of her, working up a rhythm. It wasn’t long before her legs started clamping together.

“Do you want to cum?” I asked.

She broke away from my pussy to answer. “Please make me cum, Becca. I’m so close.”

I giggled and worked my fingers even more, teasing that spongy area inside her.

Talia squealed. “That’s it. God, I’m almost there..!”

I pulled my fingers out, making her whimper and whine.

“Please don’t do this to me,” she begged. “Please make me cum.”

“You’re going to cum, but not with my fingers. If you want to cum, you’re going to use Jonah’s cock.”

My brother simply smiled at her, stroking his cock.

“I-I can’t,” she groaned, desperation laced in her weakened voice.

I climbed off the sofa and Jonah took my place. He didn’t try to fuck her. He was just there, resting his enormous cock on her pubic bush.

I couldn’t help but touch it, wrapping my fingers around it and feel it pulse in my palm. “Just pretend it’s a dildo. A big, thick, hot fleshy dildo.”

She let out a raspy sigh. “I… I won’t stop him if he enters me…”

I laughed, pressing my brother’s cock over her pussy. Jonah flexed his hips a little, making his shaft grind against her pussy.

“Fuck…” she moaned.

“It doesn’t work like that,” I said, using Jonah’s cock to slather her juices and his precum all over her sensitive clit. “Jonah isn’t going to make you do anything. You want his cock, you gotta take it yourself.”

I took her hand and wrapped her fingers around my brother’s cock.

“Go on, I know you want to,” I purred. “Feel how big and thick it is inside that tight little pussy of yours.”

She whimpered.

Jonah hissed through his teeth as I helped her guide his tip around her sensitive little clit, then down to the entrance of her pussy. Her hips quivered, grinding against him, making his tip kiss the entrance.

“Fucking hell,” my brother growled.

She held my hand as I felt him ease inside her. Her body was tensed up, so I used my finger to rub her clit in circles.

“B-Becca…”

She gritted her teeth as he slowly fed his cock into her.

I kissed her sweat shone forehead. “It’s okay, baby. It’ll feel really good soon. I promise.”

She let out a small shriek as half of his cock disappeared into her. He slowly withdrew it and pushed it back in, in a slow, continual tempo. To help her relax, I played with her clit as I lowered my mouth to her nipples and began sucking on them.

“Ah… Oh, God!”

It didn’t take long for her cries to turn into moans of pleasure. She gripped me tight as I felt her tense up from her orgasm.

“Did you cum?” Jonah asked.

She nodded weakly.

“Good girl. But we’re just getting started.”

My brother lifted her up like she weighed nothing, and sat himself down. His cock still buried partway inside her, he got her to turn and face away from him, in reverse cowgirl. Talia alternated between panting helplessly and moaning out as he impaled himself into her.

Veins bulged in his arms as he lifted and dropped her down in slow controlled strokes, until finally, he was buried all the way up inside her, all the way to the hilt.

“That’s amazing,” I said. “It’s your first time, and you took my brother all the way in you.”

Talia smiled, her eyes glazed over.

“Can you move?” Jonah groaned into her ear.

“I think so,” Talia replied.

She used her hands to hoist herself up a little on my brother’s muscular legs and started bouncing slowly. It was mesmerising to watch his cock disappear into my friend’s cunt like this.

Like a cat, I crawled up between her legs. I got the perfect view of his thick cock balls deep and stretching her tiny cunt over and over.

Instinctively, I reached under and teased my own pussy.

“Do you want to feel him cum inside you?”

She looked down at me and her eyes went wide. “W-we can’t. Not even Ben had cum inside me yet. We always used condoms.”

“Fuck, you can’t say things like that,” Jonah growled. “It’ll just make me want to do it even more. To be the first to fill this pussy up with my seed.”

“N-no…” she moaned, yet I could tell she was driving her hips down even harder on him.

“I’m not going to force you. I can alway use Becca’s cunt. Her pussy is perfect for filling.”

Talia let out a desperate, needy sound. I could tell she was close to cumming again. “I want to feel it… I want to know what’s it’s like to be filled with that much cum deep inside me.”

“There’s nothing else like it,” I purred.

I took her clit into my mouth as she drove hard up and down on my brother, pistoning his cock in and out of her.

I groped my brother’s heavy balls and felt them tighten.

“Fuck, I’m going to cum. I’m going to cum so much inside you!” Jonah said.

“Give it to me! Please!”

Jonah let out a primal growl and grabbed her breasts. I sucked on her clit to really push her over the edge.

It did the trick. Her hands shot out, digging her nails in my scalp, yanking me hard against her as she climaxed. My brother’s low guttural groans were music to my ears as he emptied his cock inside my friend.

When he was done, he lifted Talia off his cock and placed her gently beside him on the sofa. Spent, Talia just lay there, breathing hard.

I cleaned my brother’s cock off, moaning at the taste of her before prying Talia’s legs and licking her pussy clean. The taste of them together was intoxicating.

“You’re such a good little slut,” my brother said, stroking my head as I lapped up the creampie leaking out of Talia’s pussy.

It tasted amazing. I think I will make this a regular thing.

Jonah left shortly for a shower. He thanked Talia for the fuck and told me he’d give me my reward later.

Talia and I spent the rest of the evening giddy and glowing with that post sex bliss. She didn’t say no when I suggested we had to do this again.
