My Naughty Girlfriend

An house party reveals my girlfriend's true colors.

“Sweetie... you’re okay if I go alone, right?”
Tina and her younger brother were throwing a party in a large house just outside the city. My girlfriend Jenna had been invited. I hadn’t. I figured it wasn't a coincidence.
“Just watch out for Aaron,” I muttered. “I’m sure that idiot will try to hit on you tonight. If he even tries to bother you...”
“Don’t worry, I know how to handle a horny eighteen-year-old,” she interrupted with a laugh.
She was dismissive, but the knot in my stomach wouldn’t budge. Aaron, Tina’s brother, was a real ‘all muscles, no brain’ asshole. But honestly, if he were just some random gym rat, I wouldn't have cared. The problem was, he was constantly on the prowl. And he’d even hit on my Jenna.
One day, we were leaving the beach after a morning in the sun. Jenna looked killer in that tiny bikini. Then we ran into the dickhead and his usual group of idiots.
“Holy shit, look at those big boobs!” Aaron shouted. “I'd kill to get a piece of that!”
His crew burst out laughing. The asshole followed up with a blowjob gesture. Tired of his shit, I started toward him, ready to lay him out, but Jenna grabbed my arm. “He’s just an arrogant kid,” she whispered.
“A kid? I’ll teach him some manners!”
“Leave it, please. Do it for me.”
I sighed and gave in. I wanted to deck him, but I couldn't. It wasn't worth ruining Jenna’s friendship with Tina. I had to let it slide. Even if he had it coming, it wasn't worth the fallout.
“Good,” she murmured, squeezing my arm. “Just let it go.”
After that, I couldn't help but feel uneasy at the thought of Aaron being around Jenna. Still, my girlfriend had no intention of skipping the party: “Tina would be offended. She’s worked so hard on it.”
That evening, she looked stunning in a black dress that hugged all the right places, paired with heels that made her legs go on for days.
“If I didn’t know you better, I’d think you were showing off for someone,” I joked.
“Quit it,” she replied, pressing a kiss to my forehead. “Don’t wait up for me. You know how these parties go. They don’t end until dawn.”
“Oh yeah? Too bad. I was hoping you’d get bored and call me to come pick you up.”
“Sweetie, try to understand. I can't just bail, it'd look bad. We’ll see each other tomorrow, okay?”
“Okay.”
“How are you going to spend your evening?”
I shook my head. “I don’t know yet... I’ll probably just hit up some friends.”
She flashed me one last smile before slipping out the door, her heels clicking down the hallway. I stood there for a moment, letting the apartment settle back into silence. When the front door finally clicked shut, I didn’t reach for my phone. Didn’t text anyone. The idea of small talk, of drinks and half-laughs while she was out there, suddenly felt like too much effort.
So I ditched the plan and ended up on the couch, scrolling for a movie I had no intention of actually watching. But it didn’t stick. After a while, the restlessness kicked in. I couldn’t focus on the screen. My mind kept drifting back to the party: the heat, the music, Aaron hovering around her. How was Jenna behaving? And was that asshole keeping his hands to himself?
I burned through half a pack of cigarettes, but I still couldn't calm down. Time crawled, a couple of hours, maybe more. Finally, I decided to call. I didn't care if I sounded jealous or paranoid anymore.
One ring. Two. Three. Nothing. I tried again, but the result was the same. By the third attempt, I was fighting the urge to hurl the phone against the wall.
Must be the music, I told myself. She just can’t hear it.
But the idea of spending the rest of the night trapped in my own head was unbearable. I couldn't do another two hours of this. I made up my mind: I’d join her. Uninvited or not, in the middle of that chaos, nobody would notice me.
I drove to the house and parked a few meters from the open gate. The music was deafening. The front door stood wide open, lighting up the lawn where a few people were hanging out. In a dark corner, tucked away on a bench, I spotted a young couple lost in a heavy make-out session.
As expected, nobody paid me any mind. I stopped a girl I knew by sight. “Have you seen Jenna?”
“Jenna who?”
“My girlfriend.”
She looked down, suddenly flustered. “Um, no... I mean, I saw her earlier, but I don’t know where she is now.”
Before I could press her on that odd reaction, she slipped away into the crowd. I kept moving, scanning the room until I found a guy busy swigging from a vodka bottle.
“The busty one?” he laughed.
“Yeah, she’s... curvy,” I stammered. “Blonde, black dress.”
“Oh, the blondie? Yeah, I saw her.” He took another pull from the bottle. “Hard to miss in that dress, she's a total smoke show.”
“I see,” I murmured, struggling to keep my voice steady. “Do you know where she is?”
He shook his head. “I wish. I was planning to hit on her, but I haven't seen her since. Why? You know her?”
“Just a friend. I have a message for her,” I lied. After what I’d already heard, admitting I was her boyfriend felt like a mistake.
“She’s definitely getting laid tonight,” the guy observed, gulping down more vodka. “She seemed wild. Rubbing herself on everyone. A friend of mine grabbed her ass half an hour ago, and she didn't exactly push him away.”
My stomach twisted. He was just a drunk idiot, right? He had to be lying. I started to turn away, but he grabbed my arm.
“Take a sip, bro,” he said, shoving the bottle toward me.
“No, thanks.”
“Whatever. Hey, if you find that skank, send her my way.”
“Don't worry,” I muttered, pulling away.
I finally spotted Jenna in a small lounge area, crowded with tables loaded with drinks and snacks. About ten people were huddled inside, joking and drinking. A few were dancing in the cramped space.
Jenna was sitting on a small sofa. Aaron was right next to her. They didn't notice me, lost in their own conversation. With the ambient noise, I couldn’t make out a word, but then my girlfriend laughed, threw her head back, and pulled Aaron close by the hair, shoving her tongue down his throat.
That can’t be her, I thought. She's just... she's too drunk.
I watched, stunned, while they began making out passionately. The jerk caressed her thighs before moving his hands to grope her breasts. Jenna didn't shy away; she only kissed him harder.
Aaron gently took one of her hands and guided it to his lap. She pulled back for a split second, flashing him a smile. Then, I watched her unzip his pants. She tugged down his underwear, and his cock sprang out, already hard. Jenna gripped his shaft, testing his size. No one around them seemed surprised.
Not satisfied, Aaron pulled one of her breasts free from her dress to lick it. Jenna’s eyes drifted half-shut, her face masked in pure pleasure.
The world around me tilted, my vision fraying at the edges. I bolted outside for air, collapsing onto a bench to steady my racing heart.
I don't know how long I sat there in the dark, replaying the scene. I burned through a couple of cigarettes, waiting for the shaking in my legs to subside, before finally gathering the courage to go back in.
Jenna and Aaron had disappeared. Another couple had claimed the sofa. I began to pace the house, desperate to find her. I wanted to scream, to lash out, to see the guilt on her face. I needed to know how she could have done this. I wanted to hurt her the way she’d hurt me.
I searched every corner, but she had vanished. It was only after several frantic laps, my heart hammering against my ribs, that I felt a hand on my shoulder.
"Look who's here," said a voice I knew well.
I whirled around to find Aaron standing there, shirtless in just his shorts. I couldn't help but stare at his pecs and those sculpted abs. He caught me looking, shot me a challenging grin, and sneered, "What are you looking at? You ain’t turned faggot, have ya?"
"Where's Jenna?" I asked, ignoring his jab.
"Oh, you mean the bitch?" he chuckled.
"Tell me where my girlfriend is!"
"Relax, dude. She’s upstairs, first door on the right."
"Who’s she with? What's she doing?"
"Find out for yourself, cuck." He put emphasis on the last word.
I was too shocked to pay any attention to it. So I ignored him and his laughing, and bolted up the stairs. I found the first room on the right immediately, standing slightly ajar. My heart hammering, I crept closer and peeked inside.
The bastard was telling the truth: Jenna was there, on all fours on the bed, completely naked, her ass in the air. But she wasn't alone. She was passionately giving blowjobs to the two guys in front of her. The other two were behind her and were taking turns fingering her ass. This wasn't the Jenna I knew. With me, she barely sucked it a little to get it hard. But now I watched her take their hard shafts deep down her throat and hungrily lick their hairy balls.
“Look at her,” one of them growled. “Aaron wasn’t lying. The bitch is a fucking machine!”
“I do my best,” she replied, pulling her mouth off his cock.
Meanwhile, she never stopped jerking them both off. “I'm glad you're enjoying the service.”
“Where's your boyfriend?”
“Who cares? He's out with his friends, I guess... or he's at home jerking his pathetic little dick. I'm way too busy with you animals.”
“Keep going, slut!” said the other guy, grabbing a handful of her blonde hair and shoving his cock into her mouth. “Suck it like you mean it... and shut up!”
Jenna went back to giving more blowjobs. Clearly, the roughness turned her on. She was panting loudly as the two dudes behind fingered her ass.
I should have been disgusted, but the scene was perversely arousing. Jealousy twisted my stomach, but lust clouded my mind. So I continued to watch in silence, careful not to be discovered.
“Hey, guys,” she called out. “Enough with the fingers... I’m bored...” She wiggled her ass cheeks vigorously in their faces. “Please, fuck my ass!”
I watched, paralyzed, as one of the guys stepped up behind her. He grabbed her cheeks, spreading them wide to expose her flushed, throbbing anus. A heartbeat later, he pressed the head of his cock against her. Jenna let out a long, visceral gasp as he thrust deep, forcing his way through her tight sphincter.
“Yes!” Jenna moaned. “Right there! Break my ass... fill it up... you're definitely bigger than my boyfriend!”
I knew I wasn't well-endowed, but hearing her talk like that... it cut deep. I never thought Jenna was a size queen.
The anal penetration quickly turned wild. My girl’s breasts jiggled with every frantic thrust. Her voice, slurred and desperate, drifted back to me: “Finally, someone who fills me up properly... you’re so big... everything at home is so boring with that loser... compared to you, his dick is just a toy...”
“Take it all, slut!” the guy grunted. “I’m hitting your guts!”
“Yes... good... keep going... mmm... you're driving me crazy!”
The assfucking went on for endless minutes. The sound of their wild intercourse burned itself into my brain: a relentless succession of wet slaps as the guy’s balls pounded against my girlfriend’s dripping cunt. Then he announced: “I'm about to come!”
“In my ass!” she begged. “Just dump it all inside me, please!”
He filled her with cum, after which he immediately withdrew to make way for another. His friend stepped forward to take his place. But Jenna shook her head. “I want it in my pussy now.”
The guy took the hint and lay down on his back on the bed, after which she straddled him. Meanwhile, the other man approached from behind and spread her ass cheeks. His cock slowly disappeared inside her, stretching her anus.
“Mmm... good,” Jenna gasped. “Show me you're better than your friend... mmm... how beautiful... all four of you are definitely better than my pathetic boyfriend...”
My hands wouldn't stop shaking; I had to grip the doorframe just to stay upright. Luckily, I didn't make any noise, or if I did, it went unnoticed in the sexual frenzy consuming the room.
I'd seen DP in some porn and never thought I'd see it in real life. Especially with my girlfriend as the protagonist! The two guys were like they’d rehearsed it; they moved like they'd done this a hundred times before.
The one in Jenna's pussy lasted a long time. When he announced his orgasm, she invited him to come inside her. “Cum in my pussy, I'm on the pill anyway... I want to feel your hot seed inside me.”
“I'll make you pregnant, bitch!” he shouted, ignoring the fact that she was on the pill.
My girlfriend indulged him, “Yes, I want you to impregnate me! Let's give the cuck a child!”
Cuck. The word Aaron had used, a stain that was never going to wash off.
Moments later, the guy in her ass shuddered violently and emptied himself with one last series of convulsive thrusts, pumping forcefully into her. Then he pulled out with a sharp tug, leaving Jenna’s anus gaping and slippery.
Panting, my girl lifted her hips and let the other cock slide out of her pussy. A trail of cum and vaginal juices ran down her inner thighs. She lay on her back and said to the last remaining guy, "You. Come here.”
He positioned himself between her legs shamelessly spread, and sank the first thrust into her pussy. Jenna's moan echoed throughout the room. After a few rhythmic thrusts, she grabbed the guy’s glutes, and kept pulling him toward her with each thrust, making sure he was fully in.
"Yes!" she gasped, her face twisted in a grimace of pleasure. "Take it all the way in... do what you want with my pussy... use me... I'm just your whore tonight..."
They hammered at it for ages, the room filled with the wet, rhythmic slap of flesh on flesh. The other three guys were still standing there, dead silent, watching the show with hungry eyes and hands on their own cocks.
Finally, Jenna broke the rhythm. “Wanna mix it up for the finish?”
The guy stared at her, eyes wide with frantic excitement, his breath ragged. "What... do you want to do?"
"Sit on the bed," she simply replied.
He obeyed. His shaft, glistening with the vaginal juices and cum from the previous encounter, slid out of Jenna’s pussy. She knelt between his thighs, grabbed his throbbing cock and wrapped it between her soft breasts, pressing them together.
“Fuck my boobs!” she urged.
The guy didn't need a second invitation. He lunged, driving his hips forward in sharp, primal thrusts. Jenna guided him, her voice a feverish whisper: “Rub it right there... yes... feel how soft they are. Now cum... cover me.”
The guy came, stifling a cry. He completely covered her breasts, neck, and chin; it seemed like he’d never stop cumming.
Jenna laid there, panting, slick with his mess. But as the last guy pulled away, she noticed the other three fellows still standing in the room, their cocks still fully erect. Her eyes went wide with a hunger that scared me. She sat up, wiping a glob of cum from her chin, and gestured to them with a shaky, demanding hand. “You’re not done yet, are you? Come here! All of you. Get over here and finish it on me.”
The three of them didn't need to be told twice. They crowded around her, and started jerking off in unison, their eyes locked onto hers as she lay back, offering her chest like an altar. One by one, they reached their climax. The room echoed with their ragged gasps and the wet sound of them firing off, while they painted my girl’s tits with a thick, suffocating layer of jizz.
“Yes...” she whimpered, her voice barely a breath. “Make me yours... cover every inch of me!”
Watching this girl I thought I knew, now reduced to a puddle of sweat and semen, the last shred of my self-control shattered. I was just a ghost in the corner, witnessing the girl I loved replaced by someone I didn’t recognize. My arms just fell to my sides, dead weight. I felt completely numb, like I wasn't even in my own skin.
After composing themselves, the four men gathered their things and left. Fearing I’d be caught, I bolted and ducked into an empty room, waiting until I was sure they’d made it back downstairs. When I finally crept back to the room, Jenna was still there, sprawled on the bed, breathless with a dazed, satisfied smirk on her lips.
I can't describe the storm of sensations that tore through me. I’d walked in ready to scream every insult in the book, but as I stood there in front of her, my throat seized up. My brain just shut down. I could only stand there, staring at her like a man who’d lost his mind.
Jenna froze the moment she saw me, her eyes widening with a sudden, guilty recognition. Then she pointed to the crotch of my pants. I looked down, stunned to realize I had a full erection.
“You're a pervert,” she whispered. “How long have you been spying on us?”
“A while,” I admitted.
“Does it turn you on? Watching me doing all that stuff with those guys?”
I struggled for a breath. “I... I don't know what happened to me.”
“You're a pervert. And a cuck.” She gestured to her cum-smeared boobs. “Look at me. Look at all the cream those guys gave me.” Her face softened. “Come over here, sweetie.”
I sat down next to her. She gently massaged my dick over my pants, her eyes locked onto mine.
“You're so hard, honey,” she murmured. “If I give you a good wank, will you promise to forgive me?”
“Forgive you? After all this?”
“Yes.” She paused. “I love you, I really do. I need to have you by my side again. And I didn't mean to hurt you, but it was... beyond my control.”
I opened my mouth to argue, but she cut me off. “I bet your nuts are about to explode. I can help you... but you have to forgive me. I don't want to lose you.”
Her hand moved to my zipper, and she started to stroke me. “I want to be honest with you... I’ve always been attracted to Aaron...”
A cold wave of realization washed over me. She was actually admitting it. No tears, no drunken rambling. She wasn't making excuses. She did it because she wanted to.
“He’s only eighteen, but he’s so hot,” she continued.
Hot. She called that asshole’s body hot. Right now. While her hand was wrapped around my cock.
“Tonight, he didn’t leave my side for a minute. He was my shadow. Every time he touched me, every time he rubbed himself against me, every time he pressed his cock against my ass... I just lost my mind.”
She wasn't crying. She wasn't even sorry. She was casually confessing her betrayal, as if she were telling me about her day.
“Forgive me, honey! We started kissing on the sofa, I gave him a handjob, and then he asked me to follow him here. He dropped his pants, pulled it out, and I... I just knelt in front of him and took it.”
"Whore! You're a b..."
Before I could finish, Jenna pressed her tits against my face and doubled the speed of her hand. My skin felt coated in the jizz she’d received by the last guy she fucked.
"Don't get mad, babe," she moaned. "Instead of grumbling, lick my boobs a little... look how much cream there is... clean them..."
A sick, twisted urge took hold of me. Do it. Be her dog, clean her up. I stuck out my tongue and tasted the thick, salty mess of another man.
"Did he fuck you?" I managed to choke out. “Aaron, I mean.”
“Yes, honey. He fucked me hard. Like you never could. Then... then...”
“Why are you hesitating? Tell me.”
“Okay... he asked me to lick his butthole.”
“And what did you say?”
“I said yes! What could I do? I’d completely lost my mind... I was just his slut! He offered his butthole to my tongue... first I licked it all around, then I slipped my tongue inside. When he was on the verge, he grabbed my hair and shoved his cock back into my mouth.” She took a breath. “A few seconds later he came, and I drank it all!”
“And the others?” I asked, my voice trembling, my heart pounding so hard it hurt my ribs. “The four guys I saw you fuck?”
“When Aaron came, we realized they were watching. They all had their cocks in their hands...”
“Aaron invited them in, to fuck you like a whore?”
Jenna hesitated, a glint of something dark in her eyes. “Don’t get angry, please... it wasn’t just Aaron inviting them. It was me. Even after coming twice, I was so wet and desperate for more...”
“You're a disgusting whore, a...”
“Don't be like that, honey... be a good boy... lick my boobs a little more, like I did with Aaron's ass... clean all this tasty cream off me...”
I wasn't far from orgasm.
“Come on, honey, cum for me,” she urged, jerking me off faster and faster. “I know how much you want it... cum while you lick off my boobs...”
The orgasm shook me to my bones. It was more intense than anything I’d ever felt. As the tremors finally faded and I collapsed back against the pillows, the rush died down, leaving me feeling empty and sick.
“Sweetie,” she whispered, wiping her hands on the sheets. “You’re going to forgive me, right?”
