Skip to content I was driving with my girlfriend, Olivia, and my twin sister, Sasha, in the backseat. We were on our way to a spring break party at my friend’s place. All three of us were nineteen and in college.
I felt a little nervous having my sister with us. Sasha could be such a tease sometimes, especially with me. But she and Olivia were best friends, and it was Olivia’s idea to bring her along.
“You guys excited?” I asked, glancing at the rearview mirror.
Both of them nodded. Olivia had strawberry blonde hair and the kind of blue eyes that stopped you in your tracks. She was tall, with fresh, perky breasts and a perfect oval-shaped face. She was a knockout. “Our first real party,” she said.
She was right. None of us had ever been drunk before. As freshmen, we’d mostly kept to ourselves.
Oddly enough, Olivia and Sasha looked almost like twins. They were the same height, with the same hair color and similar features. Sasha had those high cheekbones that made guys stare, and yeah, she was sexy. I hated the way some of the guys in my class would talk about her, but I couldn’t really blame them. She was hot and nothing would ever change that.
Sasha leaned forward from the backseat, resting her chin on my shoulder. “You nervous?” she teased, her minty breath warm on my neck. “Afraid I’ll make out with some guys?”
I shot her a look and rolled my eyes, trying not to let her see me smirk. That was Sasha, always pushing buttons.
What set them apart was their personalities. Sasha was outgoing, bold, and the one who convinced us to go to this party in the first place. Olivia was more reserved, but she’d never say no to an adventure, especially not with Sasha involved.
By the time we pulled into the driveway, it was already dark. I greeted my friend Jack with a handshake and a quick bro-hug. He lived in a huge mansion, way out in the hills. The place was packed. Beer cups littered the tables, music blasted through the speakers, and the smell of weed floated in the air. A couple of people were already dancing by the pool table, and alcohol flowed like water.
Jack grinned and threw an arm around my shoulder. “This is gonna be a party you’ll never forget,” he said.
He wasn’t wrong. But not for the reasons I expected.
The party was in full swing. Jack and I found a pool table in the corner, half-covered in empty cups and beer bottles. We cleared it off and started a game, laughing and sipping whatever was in our red Solo cups, maybe some cheap vodka mix, but it didn’t matter. It hit fast.
“Dude, I missed this,” Jack said, lining up a shot and sinking the eight ball. “You’ve been hiding.”
“College has me in a chokehold,” I said, grinning.
He poured us both another drink, and we clinked cups before downing them.
Soon after, the music pulled me toward the dance floor, where Olivia was already moving with a group. Her hips swayed perfectly to the beat, and her eyes lit up when she saw me.
“There you are,” she said, grabbing my hand and pulling me close.
We danced for what felt like hours. Her body pressed against mine, her laugh echoing in my ear, and her heat making me aroused. We kissed between beats, touching each other lewdly. The alcohol made everything feel floaty, like nothing outside this moment existed.
Eventually, I needed a break. I stumbled off the dance floor, still grinning like an idiot, and dropped onto the couch next to who I thought was Olivia.
She leaned into me, her bare thigh brushing against mine, and her perfume, sweet and warm, wrapped around me.
“God, you smell good,” I murmured, turning toward her. She looked up, her lips parted slightly, and I leaned in.
“Whoa, slow down there, brother.” Sasha giggled, pushing a finger to my lips. “Wrong girl.”
My eyes widened. “fuck,” I muttered, pulling back.
She laughed, clearly enjoying herself. “You’re lucky I’m not offended. Must’ve really wanted to kiss me, huh?”
I rolled my eyes. “Shut up.”
She leaned into me anyway, resting her head on my shoulder like nothing happened. “You’re cute when you’re drunk.”
We stayed there for a while, sipping more drinks and watching the chaos unfold around us. Someone had jumped into the pool fully clothed. A group of girls started singing loudly from the balcony. Jack was trying to convince two strangers to shotgun beers.
The night blurred at the edges. My head buzzed, my cheeks were warm, and eventually, nature called.
“I need to piss,” I said, pushing off the couch.
Olivia appeared behind me, placing a hand on my arm. “Okay, go,” she said with a soft smile. “I’ll wait for you upstairs.”
I nodded, too tipsy to say much else, and stumbled to the bathroom. After relieving myself, I rinsed my face with cold water, trying to sober up just enough to walk straight.
When I made it upstairs, the hallway was dim and quiet. I stepped into the room Olivia had picked, the door half-open. She was already in bed, lying on her side with her back to me.
The sheets were pulled halfway over her hips, and the light from outside spilled across her bare shoulder. My heart pounded. I was still buzzing from the drinks and the dancing, and the sight of her there, waiting for me, made my cock nice and hard.
I closed the door behind me and stepped toward the bed. I slipped off my shoes and jeans. The alcohol had lowered my inhibitions, and all I could think about was fucking Olivia.
“Hey,” I whispered, sliding under the covers.
She turned toward me, her face barely visible in the darkness. Without hesitation, our lips met in a kiss. There was something different about her taste, but I chalked it up to the drinks we’d had all night.
“God, I want you,” I said against her mouth, my hands already exploring her body. Her skin felt hot beneath my fingertips as I groped her soft, perky tits that fit perfectly in my palm. Her nipple felt thicker than usual, but it just turned me on.
“Then take me,” she whispered back, her voice slightly huskier than I remembered.
We fumbled with our remaining clothes, the darkness making everything more urgent and primal. I positioned myself above her, feeling her legs spread to welcome me. My cock found her love hole, and when I pushed inside her, a groan escaped my lips. Her walls felt so much more velvety and smoother than I remembered, but I just enjoyed the ride as I started sliding in and out of her, enjoying the heat of the moment as we fucked.
After a few deep thrusts, she moaned, “Keep going, Jack.”
I froze mid-thrust. Jack? My brain struggled to process what I’d just heard. “What did you just say?” I pulled back slightly, squinting in the darkness.
“Shawn?” I heard now who she was. “Oh. My. Fucking. God!”
“Sasha?” I scrambled backward, my cock slipping out from her wet hole as I nearly fell off the bed. “What the fuck?”
We both reached for our clothes, trying to cover up our nude bodies. I could see my sister clearly now.
“I thought you were Jack!” she hissed, pulling the sheet up to cover herself. “He told me to wait for him here. I had no idea it was you.”
My stomach twisted with guilt and confusion. “Jack’s downstairs with some redhead. I saw them heading toward the pool house.”
Sasha’s face fell. “Oh.” The hurt in her voice was palpable. “He promised he would sleep with me …”
An awkward silence stretched between us. The alcohol in my system made everything feel surreal, like this was happening to someone else.
“What… what do we do now?” I finally asked, my voice barely audible.
She looked at me, her expression unreadable in the darkness. “I don’t know. But…” she said, drawing in a deep breath, “it didn’t feel bad, did it?”
My cheeks burned with shame because she was right. It didn’t feel bad at all. “Sasha, we can’t—”
“Just once,” she whispered. “No one has to know … I mean, you already fucked me.”
The rational part of my brain screamed at me to leave, to find Olivia, to forget this ever happened. But the alcohol, the adrenaline, and something else I couldn’t name kept me rooted to the spot.
“We shouldn’t,” I said, but my body was already betraying me, leaning toward her in the darkness.
“I know,” she whispered, “but I want to, and I basically got cheated on.”
The last line made me feel bad for her, and our lips met again, and my hands settled on her hips. The forbidden nature of what we were doing only intensified the sensations. Her hands roamed around my back as I fell on top of her right on the bed. I positioned myself between her legs again, my conscience drowning in alcohol and desire.
“This feels…” she said while breathing deeply against my neck.
“I know,” I replied, unable to deny the pleasure coursing through me.
I entered her slowly this time, watching her face as she arched beneath me. The moonlight filtering through the curtains cast shadows across her features, so similar yet so different from Olivia’s. I couldn’t be mad for not having seen the difference. They looked like twins. I pushed all the way in till there wasn’t an inch left, and she felt my entire length twitching inside her. Her legs wrapped around my waist, pulling me deeper.
“Oh, I feel so stretched,” she said.
“You feel so sweet,” I said as I continued to fuck her, making her tits roll up and down for every thrust.
The bed creaked beneath us as we moved faster and hornier. I kept plunging my hard-on into her pussy, feeling her walls hugging my shaft for every dive. We looked each other in the eyes. “Gosh, sis, you’re so sexy.”
“So are you, Shawn,” she said, arching her back. “You’re making me come.”
“So are you,” I said, my hips slamming into hers. “Should I come inside you?”
“Duh,” she said playfully and giggled.
She bit her lower lip as I kept fucking harder so the bed kept moving.
“Fuck, Shawn,” she moaned, throwing her head back. “I never knew you could… oh god…”
She squirmed beneath me, her body shuddering as her pussy fluttered around my shaft.
After seeing her orgasm, I couldn’t hold back anymore. I should have pulled out, but at that moment, rational thought was impossible. Pushing all the way to the hilt, I released inside her incestuous pussy, collapsing against her body as waves of pleasure crashed over us both. I lingered inside, breathing into her neck as every drop kept trickling out from my cock, painting her pussy white and creamy.
Reality came crashing back as our breathing slowed. Pulling out, I rolled onto my back, staring at the ceiling, the weight of what we’d done settling over me.
“Shit,” I muttered, sitting up abruptly. “Olivia. I need to find her before anyone realizes we’re both missing.”
Sasha nodded, pulling the sheet around herself. “Can I … can I crash with you guys tonight?” Her voice sounded more vulnerable than I’d ever heard it. “I don’t want to sleep alone.”
I hesitated, then nodded. “Yeah, okay. Just … let’s never talk about this again.”
After getting dressed, I searched through several rooms before finding Olivia curled up in a guest bedroom at the end of the hall. She was half-asleep, having kicked off her shoes but still fully clothed.
“Hey,” I whispered, sliding in beside her. “Sorry I took so long.”
She mumbled something incoherent and nestled against me. I wrapped an arm around her, guilt gnawing at my insides. Sasha slipped in, giving me a meaningful look before settling on Olivia’s other side. “Jack slept with someone else,” my sister said. “So I hope you don’t mind sleeping with you.”
“Jack’s an asshole,” Olivia murmured. She reached back to pat Sasha’s arm sympathetically.
“It’s fine,” Sasha replied. “I’m over it already.”
I lay awake long after both of them had fallen asleep, Olivia’s steady breathing against my chest and Sasha’s occasional sighs from the other side of the bed. The alcohol was wearing off, leaving me with a growing sense of dread about what morning would bring.
*****
The sunlight streaming through the window felt like daggers in my eyes. My head pounded, mouth dry as sandpaper. I groaned, trying to piece together the fragments of last night. Olivia stirred beside me, her makeup smudged across her face. Sasha was already up, sitting at the edge of the bed scrolling through her phone.
“Morning, bro,” Sasha said, her voice too cheerful for someone who’d drunk as much as we had.
Olivia mumbled something unintelligible and buried her face in the pillow. “I’m never drinking again.”
I checked my watch, nearly noon. “We should probably head out. Jack’s parents are coming back today.”
*****
We didn’t speak much as we drove home. Olivia dozed in the passenger seat while Sasha stared out the window from the back. My mind kept trying to reconstruct the night, but everything after the pool table was a blur, except for the incest sex with my sister. Of all the things I had to remember.
I dropped Olivia off first. She kissed me weakly, promised to text later, and stumbled toward her apartment building. The moment her door closed behind her, a heavy silence filled the car.
“So,” Sasha said as I pulled away from the curb. “How much do you remember about last night?”
“I sure remember the fucking,” I said. “You look a lot like Olivia.”
“I know, and we were both drunk,” she said.
I nodded, letting it sink in.
“But it wasn’t bad or anything,” she added, a small smile playing on her lips. She reached over, her hand resting on my thigh. “Actually, it was pretty good.”
“We can’t ever do that again,” I said, but my voice lacked conviction.
She leaned closer. “Why not? No one has to know. It could just be our thing.”
“Our thing?” I said, but found myself drawn to her lips. “This is so messed up.”
“Maybe,” she shrugged. “But maybe it’s worth exploring.”
Before I could respond, she kissed me. Not the sloppy, drunken kiss from last night, but something loving and intimate, something that made my heart race despite the hangover. I kissed her back, my hand finding its way to her waist.
When we broke apart, she was breathing hard. “So, what do you say?”
“I agree with you,” I said, throwing cultural norms aside. “Maybe … we should explore this.”
She beamed, looking happier than ever. “We just can’t tell anyone,” she said. “Not even Olivia.”
“No one,” I agreed, starting the car again and heading back home.
