The Ultimate Favor for Sister [MFM threesome] [non-con and con] [exhib]

“Do we have to go?” I whined.

“Yes! I told Marco I’d be there tonight and you are not going to fuck this up for me! I’m not about to show up to the biggest party of my life alone like a loser.” My sister had been one of Marco’s regular DM groupies for almost a year now. He’d never noticed she existed til this year. She says she doesn’t know why. I say the new tits are a good place to start.

I watched her pile of reject outfits grow. I needed to get the fuck away from this energy and a party could be fun. I cleaned up and decided I wasn’t going to mimic my sister’s closet warzone and opted for something understated. I pulled on an oversized Metallica tee I’d turned into a cute tank and some distressed jean booty shorts.

With some sea salt spray in my choppy hair and thick cat eyeliner I was ready to go. My sister, ever the Instagram party girl, decided a corset dress with ‘fuck me’ slits down the front and up the side and influencer level makeup was what this occasion called for. “Subtle,” I tossed underhandedly.

“Fuck off,” she scoffed as we left.

I had heard Marco Li Fonti’s house parties were massive but I wasn’t expecting this. It was only 9:30 and I could tell from outside the house was packed. The second we crossed the threshold of the front door, my sister gripped my arm painfully, wildly scanning the crowd. “What if he isn’t here?” she panicked.

“It’s his fucking house. Of course he’s here.” I pried her bony fingers off me.

“You have to stay with me until I see him.” We had started wandering through the living room into the kitchen.

“I’m not going anywhere,” I assured, “Besides, I don’t know anyone here any-”

“MARCO!” she shrilled.

I jumped out of my skin, holding my left ear which was surely damaged. Standing in the kitchen, leaned against the counter with all the booze, surrounded by at least five girls, was Marco. I almost started laughing at how stereotypical this was. I had hoped my little sister had some sort of imagination when it came to type but this guy was the pinnacle of gym rat, Jersey Shore douche. Black V-neck, gold chain, dark jeans, white sneakers that looked fresh out of the box. His first words as a baby were probably, “I’ll call you tomorrow.” The only thing he didn’t have was the crunchy, slicked back hair. Instead he had on a backwards flat cap. I would’ve preferred the hair.

“Hey, baby!” he replied, opening his arms. I threw up in my mouth. Before I could give her any semblance of a farewell, she booked it right to him and he wasted no time to place his hand firmly on her ass. A quick glance at my sister let me know she was consenting to this so I saw no reason to stick around. I filled a Solo cup with whatever bright pink jungle juice was available as I watched all the other girls stare daggers at my sister. I’d have my hackles up if a bitch wanted to get squirrely.

I decided to meander the rest of the house and the amount of fakery and fronting that permeated made me ill. Every boy was bouncing around from girl to girl until they could find one that would peel their eyes away from their selfies long enough to grind on their dicks for a song or two. This wasn’t my idea of a good time. My drink was gone quicker than I realized. I headed back to the kitchen for another.

Marco and his pussy posse had gone elsewhere. I scanned the room for any semblance of intelligent life and was, delightfully, met with a cute guy who quickly looked away when I made eye contact. Bingo.

I made my way over to the breakfast nook table he was chilling by with a couple friends who were in their own conversation. “Do you hate this party as much as I do?” I asked.

He laughed. “Dude, I don’t even know why I came.”

“Well, I’m here because my sister’s scheduled to fuck the host tonight.”

“Right on, right on,” he said playfully. This guy was funny.

“Olivia.” I stuck out my hand.

“Stanley.” He shook it.

He was really cute. He looked like he was probably white blonde as a child but had grown nearly brunette with age. He had laugh lines around his blue eyes and his bottom two teeth were perfectly crooked. I’d probably have to get on my tiptoes to kiss him..

“…join me?” He had been saying something while I checked him out. I looked down at what he had just extended toward me. It was a joint. I could use some of the Devil’s jazz to take the edge off and this sugary punch was honestly gross.

“Yeah, sure!” I smiled. We headed toward the back door conveniently located in the kitchen where we were standing. Marco, of course, had a fairly large wrap-around porch that was well decorated with plenty of seating. It was only slightly less crowded than inside with a couple people spilling onto the stairs and into the yard. Beyond the glow of the outdoor string lighting sat a garden shed.

“You wanna duck behind there so we don’t get yelled at?” he asked. A chance to be alone with him? Absolutely. We made our way in that direction, our path lit by a single street lamp.

He pulled out a nifty lighter shaped like a pack of gum and lit the joint. I’d been partaking in the greenery since I was a young teenager. My mother thinks I wasn’t a mouthy youth because she raised me well. Little did she know.. He pulled a drag off it like an old Hollywood star then passed it to me. I took my first puff unable to stop myself from remembering sex while high was my favorite.

Throughout the session I learned he’d moved here for our arts conservatory and was in his final year of their film program. He was here because the “private” Facebook invite got shared around so much it was practically public, hence the very large crowd. “My buddies and I didn’t have anything better to do,” he said crushing the roach of the completed joint into the dirt under his foot. “Maybe you could be part of my final film project?” Before I could answer, we were interrupted.

“There you are!” It was Marco. What the hell?

“Hey, man..” I said, not hiding my confusion, “What’s up?”

“Just wanted to see where my favorite girl was hiding!” His favorite girl? Stanley’s look at me reflected my confusion. I was pretty high but weed doesn’t make you hallucinate.

“Where’s my sister?”

“With one of her friends or something.” He waved his hand toward the direction of the house like he was shooing the idea of her away. “The only reason I invited her in the first place was so I could get close to you.”

I had had enough of this shit. “Marco, everyone in that house can tell how much my sister likes you. This is super uncool.”

“If you let me fuck you, I’ll date her.” The statement hung in the air like ice. I was shocked when a retort didn’t fly out of my mouth immediately. My sister’s self-esteem is borderline zero. Our mother wasn’t the kindest growing up. I took her criticisms and threw them out the window. I never let her get to me. My sister, on the other hand, wore each of them like a scar. Marco’s the first person she’s ever pursued and I felt in my bones that if she’d get him out of her system she’d have the confidence to go after someone actually worth it! Her year long, at times desperate, chase of him meant he knew as well as I how insecure she was.

“Hey, dude, that’s-”

“Ok.” I interrupted Stanley. His jaw dropped slightly. “But he gets to stay to keep watch. If my sister catches us she’ll never speak to me again.”

Marco shrugged and made his way over to me, unzipping his pants. Stanley didn’t drop the shocked look but did as I asked and stood at the corner Marco approached from. It was the only direction to get back here.

I pulled my shorts and thong down as Marco pulled his package out. I cursed internally as I felt my pussy react instinctively to it. Please forgive me for this but it truly was an Italian sausage. From the street light I could tell he was big with the kind of mushroom cap that’d ‘pop’ in and out of me. I bent over without trying to make it look medical as he readied himself behind me. He spit in his hand and rubbed it on his very erect cock. Stanley was at his post but his eyes were glued to us. I decided I’d get through this by pretending he was the one fucking me. I met his gaze which softened the shocked look slightly.

As I should’ve guessed, Marco wasn’t going to make this simple. He took his fat head and rubbed it up and down my slit. “That’s right. Mommy’s getting wet for me.”

“Just get this over with,” I said, never looking away from Stanley. This guy knew what he was doing. I’m proud of the fact that I’m tight and he entered me slowly, thrusting in one inch at a time as my juices coated him. Once he was all the way in, a moan escaped my mouth. Rather than roll my eyes or curse myself, I focused all the energy on Stanley and bit my lip, full eye contact. Stanley took a deep breath in response. I definitely had his attention.

Marco was savoring this. I fully expecting him to get to business, full speed ahead. Instead he continued to pull in and out, one inch at a time, emitting a sighed “yeah” every so often. If this were Stanley I’d be going wild for this but the sooner Marco was done, the better. “Speed it up.”

“Mommy likes it fast?” Marco chuckled, pleasure dripping in his voice.

“I’m not your Mommy,” I spat over my shoulder.

“You are until I cum,” he countered. With that, he took full grip of my hips and began fucking me quickly. I could hear what I was sure was massive balls hitting the inside of his jeans. Objectively, he was a great fuck.

The joint fully took its hold allowing me to sort of enjoy this. I let my breath quicken as I parted my lips sensually for Stanley. He stared at them longingly. I gave him the ‘come hither’ finger. Trance-like, Stanley took the short two steps toward me. I grabbed him and unzipped his pants the moment he was within reach. He wasn’t wearing any underwear so his cock flew out of the zipper hole like a rocket. My pussy flexed which caused Marco to moan.

Stanley’s dick was much more my speed: average size and girth with a proportionate head. I could take him in any hole fully and deeply which is just the way I like it. The second he was in my hand I took him into my mouth. My tongue made contact and Stanley closed his eyes and dropped his head back. My left hand rubbed at his balls through his jeans.

Marco’s thrusts were pushing Stanley deeper down my throat, which we both loved. He signaled his enjoyment by brushing my hair out of my face and holding it tightly above my head. I made eye contact and slightly nodded. He caught my drift as he took my hair in both his hands and appropriately, almost gentlemanly, began fucking my mouth. The two men were alternating thrusts and I felt like a piston in a hot rod.

Marco’s grunts were borderline prehistoric when he pulled out suddenly. Before I could object I felt his hot load erupt all over my ass cheeks. I used the raw energy to jack and suck Stanley quicker than I had yet.

“I knew you’d be a decent lay,” Marco cooed, putting his dick away. He continued spouting some macho bullshit about his conquest when I abruptly pulled Stanley out of my mouth.

“Go away or shut the fuck up and watch.” Marco’s chest deflated as he adopted the look of an eager boy at Christmas. I looked to Stanley for any objection but it was clear he just wanted his cock back in my mouth. I obliged and greedily took him to his base, licking in circles on his pelvis around him. My next break to jack him off he gripped my hair tighter. I looked up at him and was met with a nod. He was close.

I grinned before greedily enveloping his upper half while jacking off his lower. I was keeping a picture perfect pace when I heard, “Olivia..” That was the only warning I was going to receive. I braced for the first shot and tasted him. I hungrily swallowed as he moaned rope after rope down my throat. He had to physically stop me from continuing. I was insatiable.

He quickly put himself away as I barked “Towel” at Marco.

He was transfixed on us, mouth slightly agape before laughing incredulously.

“You came on my ass, you get me a towel.” He could see I wasn’t messing around and walked defeated back toward the house.

“That was incredible,” Stanley breathed as soon as Marco was out of earshot.

“I had to thank you for keeping watch,” I gushed.

“Yeah, but how do I thank you?” He had a smokiness to his voice I hadn’t heard yet.

“Once I get myself cleaned up I can show you.”

He rubbed his thumb across my plump lower lip. “I would fucking rock your world, you know that?”

“Don’t make a promise you can’t keep.” He chuckled almost villainously as Marco came back with a kitchen towel. I quickly wiped any evidence of him off me and chucked the towel into the hedges nearby.

“Hey!” Marco exclaimed as I took Stanley by the arm and led him back toward the house. After finding the downstairs bathroom occupied we tried the one upstairs. Fortunately, someone left it as we approached.

Once the door was locked behind us, my mouth was on his. His hands were all over me. As I suspected, I did have to reach a bit to kiss him and, sensing my effort, he easily swooped me up, an ass cheek in each hand. I wrapped my legs around him and tangled my fingers in his thick hair. He carefully walked us toward the gigantic tub in the corner and sat me on the edge.

I pouted at having his tongue away from mine when he said, “Get in.”

I curiously swung my legs over the side and sat in the basin with my back against the side furthest from the faucet. “Like this?” I asked coyly.

He nodded, smiling slightly as he climbed in after me. Rather than continue to kiss me, he wasted no time showing his intentions. He laid flat on his stomach, legs bent at the knees with his shins parallel to the tub’s side, his Vans on either side of the faucet. I spread my legs instinctively and was rewarded with deep kisses down my inner thighs. He planted a big one directly on my pussy over my shorts and I jumped with pleasure. He continued his pussy kisses as he sightlessly unbuttoned and unzipped me. I raised my ass off the tub’s floor enough for him to pull my pants and panties down. My cheeks were freezing against the cold fiberglass but my cunt was radiating warmth.

Wordlessly, he plunged his tongue deeply into me and moaned deeply at the taste. “Am I yummy?” I asked, wrapping one of his curls around my finger.

He rolled his eyes into the back of his head and nodded, fully eating me now. I gripped his head and threw my own back. His strong tongue flicked rapidly against my fully engorged clit as I felt myself begin to pool in front of my ass cheeks. “Eat it, baby, eat it so fucking good.” My voice unintentionally mimicked a porn star’s and it only encouraged him. Taking a leg in each hand, he pulled me toward him, pushing his face into my pussy hard. He methodically switched back and forth between slurping up my juices and hitting my clit in just the right spot.

“Stanley..” I was going to give him a similar warning. He made eye contact to let me know he heard me but didn’t let up. “Stanley!” I said more sharply. It came quicker than I’d expected. His thick mane were my handlebars as I shoved his face somehow even further into my pussy. In that moment, he and I were the only two people in the world. My orgasm burst out of my mouth loudly masked outside by Jonas Brothers’ “Sucker”. I moaned fully and deeply as my cunt tightened over and over, my clit sparkling. After the second moan, Stanley joined me, his vibrations aiding in my pleasure.

I gave him a pat on the head to signal I was done but it went unanswered. Eyes still closed, Stanley continued to eat me as if nothing had changed. My clit was hella sensitive and I tried to squirm away. He tightened his grip on my thighs and stared me directly in the eyes as he continued. I wasn’t going anywhere. The realization softened my sensitive stabs to heightened revelry. He took the first and second fingers of his right hand and began fucking me with them, his mouth still a vice grip on my clit. I was done for. He responded to the first buck against his face by keeping those fingers deep in me and vibrating them around. I thought my hips were going to snap as I unabashedly rode his face and came again. He couldn’t get deep enough.

I was certain he’d worked me back up to be ready for a third O when he pulled away breathlessly. Before he could wipe his face I pulled him by his collar up to me. He was shiny from under his nose all the way down his chin. I licked myself off him as he moaned quietly. We sat in the tub making out for a couple more minutes until someone knocked at the door.

“We should probably head back down,” he suggested. I had to sternly shake the urges of sucking his cock again and got redressed. We walked together downstairs where I was beyond pleased to see Marco had kept good on his word. My sister was sitting on his lap on the couch where they were both chatting happily to others. She saw me and mouthed, “He asked me out!” I’d never seen her so happy.

“I rolled another one. Wanna meet some of my friends around it?” he smiled, sheepishly.

“You’ve gotta get the smell of my pussy off your breath somehow,” I said mischievously..

He slightly bit his lip and wrinkled his nose with delight. “You’re fun. C’mon.”

“I did. Twice already. Man, you make this too easy.”

He shook his head and rolled his eyes with an exasperated sigh as we walked back toward the kitchen to his friends.
