Caught me 2 elder sisters fucking each other

**My Confession**

This happened two years ago, summer of 2023. I’m Ethan, 18, living with my sisters, Mia (20) and Ava (24), in our suburban house. Mom and Dad were away for a week, leaving us alone. This is how it unfolded, step by step, no bullshit.

It was a muggy afternoon, and I was restless, pacing upstairs. I heard soft moans from Ava’s room, door slightly ajar. I peeked in. Ava was naked on her bed, legs spread. She’s tall, curvy, with big, round tits, dark nipples, and thick hips. Her pussy was shaved, a silver butt plug nestled between her cheeks. Mia, petite and blonde, with small, perky tits and a tight, round ass, was between Ava’s thighs, licking her clit while sliding a pink dildo in and out, her own butt plug glinting. Ava’s moans were low, her hips twitching. My cock stiffened in my shorts. My sisters were fucking.

Ava’s eyes caught me. “Ethan! What the hell?” she shouted, grabbing a sheet to cover her tits. Mia spun around, dropping the dildo, snatching a pillow. “Oh my God, Ethan, get out!” she yelled, face flushed. “What are you even doing up here?”

“I didn’t mean to,” I stammered, frozen, my erection obvious.

“What the fuck are you doing spying?” Ava snapped. “How long were you there? Tell me right now.”

“Just now!” I said, hands up. “I heard noises, I swear. I wasn’t trying to—”

Mia cut me off. “You can’t tell anyone, Ethan. You get that? Swear to me you won’t.”

“I won’t,” I said. “I promise.”

Ava’s eyes narrowed. “Don’t say a word to anyone,” she said, low and firm. “I’ll get you that PS4 you want. Deal? But you better mean it.”

“Yeah, okay,” I said, nodding fast.

Mia turned on Ava. “A PS4? Ava, what? He shouldn’t even be here! This is crazy. What if he tells Mom and Dad?”

Ava clutched the sheet. “What else do we do, Mia? Let him run off and blab? We have to make sure he stays quiet.”

“I’m not telling,” I said. “I swear on everything.”

Ava stared at me. “You wanna watch?” she asked, her voice caught between challenge and uncertainty.

Mia’s jaw dropped. “Ava, are you fucking insane? He’s our brother! Watch what? No way in hell.”

“He’s already seen us,” Ava said, steady. “Better he’s in here than sneaking outside, Mia. What if he goes and tells someone anyway?”

Mia shook her head. “This is so wrong. I can’t believe you’re okay with this.”

Ava leaned closer to her. “Mia, he’s not gonna talk if we keep him close. Right, Ethan? Say it.”

I nodded. “Right.”

Mia paused, eyes flicking to me, then Ava. “Fine. But I hate this. And if you say one word, Ethan, I’ll kill you myself.”

“Sit,” Ava said, pointing to a chair by the bed. I sat, hands gripping my shorts, my dick aching. Mia hesitated, her eyes darting to the door, then dropped the pillow, her small tits and tight body exposed, the butt plug still in place. She lay back, legs open, glaring at me. “Don’t you dare move,” she said. Ava knelt, licking Mia’s pussy slow, then slid the dildo in deep, the butt plug shifting slightly. Mia moaned, soft at first, then louder, her slim body tensing, small tits perky. Ava’s curvy hips swayed, her tits bouncing, her own butt plug glinting. “Don’t touch yourself, Ethan. Just watch,” Ava said, glancing at me. I nodded. Mia came, hips jerking, eyes shut, a sharp moan escaping. They kissed after, tongues sloppy, whispering to each other, ignoring me. I bolted to my room, locked the door, jerked off, and came hard, their bodies burned into my brain.

Days were heavy with tension. Mia avoided me, her slim frame slipping past at breakfast, her small tits poking through thin tank tops, the faint outline of her butt plug sometimes visible under tight shorts. Ava was bolder, her big tits and round ass on display in low-cut tops and leggings, her butt plug a secret I couldn’t unsee. They’d whisper when I entered a room, their eyes flicking to me, like they were debating what to do with me. One morning, I caught Mia staring at me over coffee. “You haven’t said anything, right?” she asked, her voice low, almost accusing, as she stirred her mug. “No,” I said, avoiding her eyes. Ava, leaning against the counter, her cleavage spilling out, smirked. “Good boy. Keep it that way.” That night, during a movie on the couch, Mia’s bare leg brushed mine. She froze, then pulled away. “Don’t get any ideas,” she muttered. Ava chuckled, her hand grazing my arm, lingering too long. “He’s behaving, Mia. Relax.”

A week later, Ava called me to her room, her voice hesitant. “Want another look?” she asked, peeling off her shirt, her big tits bouncing free. Mia stood by the bed, arms crossed, frowning. “Ava, I don’t know about this. It’s weird. What if he tells someone? We can’t trust him yet.”

Ava touched her arm gently. “He’s kept quiet so far, Mia. Let’s keep him happy. Otherwise, what? We fight him out the door?”

Mia sighed, her face conflicted. “Fine, but I’m watching him.” She stripped, her perky tits and tight ass bare, the butt plug still in. Ava’s thick hips and big tits were exposed as she undressed. They kissed, slow and nervous, their tongues meeting briefly, glancing at me like I might bolt. Ava lay back, legs spread, the butt plug glinting. Mia licked her pussy, then slid the dildo in, slow and careful. I rubbed my cock through my shorts, the bulge obvious. “Fuck, Ethan,” Mia muttered, glancing over, her cheeks red. “You’re really doing that?” Ava moaned, her thick thighs trembling as she came, the dildo deep, her butt plug shifting. I stopped myself, shorts damp with precum, heart racing. They didn’t look at me after, just curled up together, whispering. “See? He didn’t say shit,” Ava said to Mia.

The teasing built slowly, deliberate. Mia started lingering in the kitchen, bending over to grab something from a low cabinet, her tight ass barely covered, the butt plug’s outline faint. Ava brushed past me in the hallway, her big tits grazing my arm, whispering, “Still thinking about us?” with a half-smile. At dinner, they’d sit close, their legs touching under the table, glancing at me when they thought I wasn’t looking. “Pass the salt,” Mia said one night, her foot nudging mine under the table. “And remember what we said,” Ava added, her eyes on me. I couldn’t stop replaying their moans, their bodies. Two weeks later, Ava’s room again. Mia was on her back, legs spread, Ava eating her pussy, the dildo pumping, their butt plugs in place. “You want to see up close?” Ava asked, her voice low, eyes locked on mine. I nodded, throat tight. “Come near the bed,” she said. I sat beside them, my cock throbbing, my hands shaking. Ava’s big tits bounced as she licked Mia’s clit, the dildo sliding deep, Mia’s slim body trembling, her small tits perky. “You want to touch?” Ava asked, her tone cautious, her eyes flicking to Mia. I nodded again. “Go ahead, but nothing crazy,” Mia said, her voice sharp. I touched Ava’s thigh, warm and soft, then her big tit, her nipple hard under my fingers. “Go ahead, take it in your mouth,” Ava said, her voice low. I leaned in, sucking her nipple, my tongue flicking it. Mia watched, moaning. “This is nuts,” she muttered. Ava came on Mia’s tongue, her pussy soaking, thighs shaking. I came in my shorts, humiliated, and ran out, their soft, nervous laughter trailing behind me. “He’s hooked,” Ava said.

Weeks later, after more stolen glances and tense silences, Mia’s room. They were naked, Ava’s curvy body on the bed, Mia’s slim frame beside her, both with butt plugs in. “You’re not gonna open your mouth to anyone about this,” Ava said, her voice firm, guiding my hand to her pussy, wet and hot. “Swear it again.” My cock was rock-hard, straining. “I swear,” I said. “You want to taste the pussy?” Ava asked. I nodded. She guided my head down, and I licked her clit, her taste sharp and wet. Mia stared, her eyes flicking to my crotch. “Jesus, Ethan, didn’t think you had such a dick. Thought you were small,” she said, her voice sharp with surprise. She paused, then asked, “Want help?” She pulled my shorts down, grabbed my cock, jerking slow. “Don’t make a mess,” she added. I groaned, my tongue on Ava’s pussy, my fingers clumsy. Mia’s hand was firm, stroking faster, her small tits bouncing slightly. Ava came on my mouth, moaning loud, her thighs trembling, her butt plug shifting. I pulled back, warning, “I’m close.” Mia pulled her hand away. “Say when you’re close, don’t you dare cum in my mouth,” she said. I came a lot on her fist and the floor, ropes of cum splattering. They stared, shocked. “How can you do that?” Ava asked. “That’s a ton.” “Do you remember when me and Mom had to visit the doctor a few years ago, they said it’s hyperspermia,” I said, panting. “Fuck,” Mia muttered, wiping her hand.

More weeks passed, the tension thicker. One night, we were in Ava’s room, the three of us tangled up, Mia sucking my cock while I fingered Ava’s pussy. Their moans filled the air, the dildo on the nightstand, butt plugs still in. Suddenly, headlights flashed through the window—a car pulling into the driveway. “Shit!” Ava whispered, yanking the sheet over us. Mia pulled off my cock, grabbing pillows to cover herself, her face pale. “Who is that?” she hissed. We froze, hearts pounding, as footsteps crunched on the gravel outside. It was just a neighbor dropping off mail, but we lay there, barely breathing, until the car pulled away. “Too close,” Mia said, her voice shaky. “We can’t do this with the window open anymore.” In Ava’s room later that night, they knelt in front of me, naked, their butt plugs glinting. Ava’s big tits pressed against my thigh, Mia’s small tits perky. “Ready for more?” Ava asked, her voice soft but daring. I nodded. “Don’t fuck this up,” Mia said. Mia sucked my cock, her mouth tight, tongue swirling. I fingered Ava’s pussy, my fingers deep. Ava joined the blowjob, her lips on the tip, their tongues meeting. “Say when you’re close,” Mia said. I forgot, lost in Ava’s wet pussy. I came in Mia’s mouth, hard and fast. She gasped, swallowing some, cum overflowing, dripping to her breasts. “Wtf, Ethan, couldn’t you have said?” she said, spitting some out. Ava laughed. “He’s got a lot, remember?” I touched Mia’s tight ass, feeling the butt plug’s base, then Ava’s soft, heavy tits, her nipples hard. Ava kissed me, her tongue deep and hungry, then Mia, her kiss softer, hesitant. “You like that?” Ava asked between kisses.

Finally, one night, Ava’s bed. They were naked, Ava’s curvy body spread out, Mia’s slim frame beside her, butt plugs in place. “You ever done it?” Ava asked, her eyes searching mine, her voice careful. I shook my head. “No.” Mia bit her lip, her face tense. “Ava, this is too much. What if someone finds out? We can’t go there.” Ava touched her hand gently. “We’re in this, Mia. No one’s finding out. Trust me.” Ava spread her thick thighs. “Fuck me, Ethan.” I pushed into her pussy, tight and wet, my cock throbbing. It was too much—I came fast, in seconds, my body shaking, cum filling her until it started dripping from her pussy, white and thick. Mia gasped, “What the fuck, you came inside her?” Ava laughed, her big tits jiggling, her tone calm. “It’s fine, Mia.” They both laughed, Mia’s face softening. “It’s okay,” Ava said, smiling at me. “Happens with everyone.” Mia straddled Ava’s face, her small tits bouncing as Ava licked her pussy, slow and deep, the butt plug shifting in Mia’s ass.

They shifted, Ava and Mia scissoring, their pussies grinding together, wet and loud, butt plugs glinting. Mia moaned, her slim body trembling, small tits bouncing. Ava’s curvy hips rocked, her big tits swaying. “Fuck her, Ethan,” Ava said, her voice husky. I pushed into Mia’s tight pussy, her gasp sharp. “Holy shit,” she said, her ass clenching around the butt plug. I fucked her slow, her small tits bouncing, her slim legs wrapping around me. Ava knelt, licking Mia’s clit while I fucked her, sliding the dildo into her own pussy, her butt plug in place. Mia came, her pussy squeezing me, her cries loud. I pulled out, Ava’s hand jerking me fast. “Cum on her,” she said. I came on Mia’s tits, my vision blurring.

They didn’t stop. Ava lay back, legs spread. “My turn,” she said. I fucked her again, slower, her thick thighs around me, her pussy wet and tight. Mia kissed Ava, then me, her tongue hungry. Ava pushed Mia down, eating her pussy, her tongue flicking fast, the dildo in Mia’s pussy now, sliding deep, Mia’s butt plug shifting as she moaned. Mia’s slim legs spread wide, her cries sharp. I fucked Ava harder, her big tits bouncing, her pussy gripping me. They scissored again, pussies grinding, the dildo in Ava’s hand fucking Mia, their butt plugs glinting, their moans mixing. Ava came, her pussy soaking, then Mia, her cries loud. I pulled out, Ava and Mia’s hands jerking me together. I came on Ava’s tits, shaking. Ava licked the cum off, kissing Mia, tongues messy. Mia kissed me after, her lips salty, her slim body trembling.

We kept going, sneaking around, their bodies—Mia’s tight frame, Ava’s full curves—pulling me in. The dildo and butt plugs were always there, Ava using them on Mia, Mia on Ava, their pussy eating and scissoring driving me crazy.
