Emma's moans were getting louder, shameless, filling her bedroom like a filthy confession.
Jake stood frozen in the cracked doorway, the book he'd meant to return hanging limp in his left hand. His eyes were glued to the obscene sight on the bed—his little sister, completely naked, legs spread obscenely wide, three fingers buried knuckle-deep in her dripping cunt. Her hips bucked frantically as she fucked herself, tits bouncing with every thrust, nipples stiff and flushed. Slick sounds—wet, messy, obscene—echoed with every plunge of her fingers.
And she was moaning his best friend's name.
"Fuck… Liam… right there… please…"
Jake's cock surged to full hardness so fast it hurt. His basketball shorts tented obscenely. Shame burned in his chest, but his hand moved anyway, slipping under the waistband before he could stop himself. He wrapped his fist around his throbbing dick and started stroking—slow at first, then faster, matching the rhythm of Emma's fingers. Pre-cum leaked over his knuckles as he watched her shove a fourth finger inside herself, stretching that tight pink hole he was never supposed to see.
"Jesus Christ, Emma…" he breathed, barely audible. His strokes grew rougher, thumb smearing the slick head of his cock while he stared at her swollen clit, at Liam's dried cum still glistening on her thighs, at the way her pussy clenched and fluttered around her own fingers. He was leaking like a faucet, shame and lust twisting together into something sick and addictive.
He didn't hear Liam approach.
Liam moved like a predator—silent, barefoot, wearing nothing but loose gray sweatpants. He stopped right behind Jake, close enough to see everything: Jake's hand frantically jerking his cock, the way his hips jerked forward, the hungry stare fixed on his own sister's spread cunt.
Liam's lips curled into a dark, satisfied smirk. He leaned in until his mouth brushed Jake's ear and whispered, low and venomous:
"Jerking off watching your sister? That the kind of intentions you have toward her, bro?"
Jake jolted like he'd been electrocuted. His hand froze mid-stroke on his cock. Before he could even turn, Liam's words sank in and Jake spun, eyes wide with panic. He slammed his free hand over Liam's mouth, the other still gripping his exposed, leaking dick.
"Shut the fuck up—" Jake hissed, voice shaking. He shoved Liam backward down the hall, away from Emma's door, his hard cock still swinging obscenely between his legs, completely forgotten in his rush. Pre-cum dripped onto the wooden floor as he dragged his best friend into the guest room and kicked the door shut behind them.
Inside, Jake's back hit the wall. His chest heaved. His cock was still rock-hard, angry red, veins bulging, a thick bead of pre-cum rolling down the shaft. He finally seemed to realize it was out and tried to shove it back into his shorts, but his hands were trembling too badly.
"Liam… I know what I did was wrong," Jake stammered, voice cracking with shame. "But you fucked my sister, didn't you? I saw the way she looked when she came out of your room. I heard—"
Liam didn't answer right away. He just stared at Jake with that cruel, knowing smirk, eyes flicking down to his best friend's exposed cock. Then he laughed—low, dark, and utterly in control.
"Oh, I fucked her alright," Liam said, voice dripping with smug satisfaction. "Railed that tight little virgin cunt raw while you were in the shower. Filled her up so deep she's still leaking my cum right now. That's what you were jerking off to, bro—your baby sister playing with the load I pumped into her."
Jake's face burned crimson. He opened his mouth, but nothing came out.
Liam stepped closer, towering, radiating pure dominance. "You've been my friend for years, man. And here you are, cock in hand, watching your own sister finger-fuck herself and moaning my name. That's some nasty incest shit you're into. Kinda gross, don't you think?"
He reached down and casually shoved his own sweatpants down. His massive cock sprang free—heavy, thick, still slightly shiny from Emma's pussy and his own earlier release. It was noticeably bigger than Jake's. Liam wrapped a hand around the base and gave it one slow, lazy stroke, right in front of his best friend.
"Look at this," Liam growled, voice low and filthy. "This is what ruined your sister's virgin hole. She was so fucking tight the first time I pushed in she whimpered like a little kitten. Took every inch though. Milked me dry. Now that pretty cunt only knows my shape. Anything smaller's gonna feel like a fucking needle to her. She'll never be satisfied with some tiny-dick loser again."
Jake stared, dumbfounded, eyes locked on Liam's huge cock as his best friend stroked it shamelessly.
Liam's smirk widened into something evil. "I'm not done with her. Not even close. Next time I get her alone I'm gonna fuck her even harder. Bend her over and breed that womb deep. Gonna pump her full of my cum until it takes. She'll be carrying my baby before you even figure out how to stop jerking off to the thought of it."
He gave his cock another slow, deliberate stroke, thumb rubbing over the fat, leaking head. "You gonna keep watching, Jake? Hide in the hallway and stroke that sad little dick while I turn your sister into my personal cumdump? Or are you finally gonna admit how fucked up you are?"
Jake stood there, pants around his thighs, cock still hard and betrayed, shame and horror and unwanted arousal twisting across his face. Liam just kept stroking, eyes gleaming with dark triumph, waiting for his best friend to break.
Down the hall, Emma's muffled cry of release echoed faintly through the door as she came again completely unaware of the two men fighting for control of her body and her future just a few feet away.
