Hiro buried his face even deeper between Anna's ass cheeks, devouring her mercilessly. His tongue moved with voracious hunger: he licked from her swollen clit all the way up to her puckered asshole again and again, leaving long, hot trails of saliva that dripped down over the lips of her pussy. He sucked her clit hard, pulling it between his lips while whipping it with the tip of his tongue in fast circular motions. Anna panted brokenly, her knees shaking as she struggled to stay on her feet against the sink.
"Mmm… what a delicious pussy you have, little sis," Hiro growled against her soaked skin, the vibration of his voice making Anna clench. "You're dripping… look at how you're soaking my face."
He spread her ass cheeks even wider with his hands, leaving her asshole completely exposed, and drove his tongue straight into it, tongue-fucking her ass while two fingers slid into her drenched cunt. He curled them upward, rubbing that sensitive spot inside her with quick, precise strokes at the same time his mouth sucked and licked her asshole without pause. Anna let out a louder moan, her hips moving involuntarily backward, desperately seeking more of that wicked tongue that was driving her crazy.
Hiro alternated without mercy: deep tongue in her pussy, slurping up her juices with obscene wet sounds, then back to her asshole, penetrating it with the rigid tip of his tongue while his fingers fucked her faster and faster. The wet squelching of his fingers sliding in and out, mixed with Anna's muffled moans and Hiro's pleasure-filled grunts, filled the kitchen.
Suddenly, Hiro stood up. His cock was rock-hard, throbbing inside his pants. He unzipped and pulled it out—thick, veiny, the head already glistening with precum. Without saying a word, he placed the tip against Anna's soaked entrance and slammed all the way in with one brutal thrust.
"Ahhh… fuck, you're so tight," he grunted, gripping her hips with both hands.
He started fucking her with deep, rapid thrusts, the sound of his hips slapping against Anna's ass echoing through the kitchen. Every time he buried himself to the hilt, his balls smacked against her clit, sending waves of pleasure through both of them. Anna bit her lower lip hard, trying not to scream, trying to make sure their mother wouldn't hear her moans of pleasure, while her pussy clenched tightly around her brother's thick cock.
Hiro picked up the pace, fucking her hard. One hand moved up to grab her hair and yank her head back as he pounded her without mercy.
"This is what you wanted, right? To get fucked like the slut you are…" he whispered close to her ear, biting her lobe.
They were in the middle of their frenzied fucking when, suddenly…
Ding-dong!
The doorbell rang loudly, shattering the wild rhythm.
Hiro stopped dead, still buried to the balls inside Anna, his cock throbbing inside her hot, tight cunt. Both of them froze, breathing heavily.
"Who the fuck is that at this hour?" Hiro muttered, not pulling out, only turning his head slightly toward the front door.
Anna, face flushed red with her panties still around her knees, trembled against him, her pussy involuntarily clenching around his cock from the shock.
The doorbell rang again, more insistently.
Hiro let out a frustrated growl, but a dangerous smile spread across his lips.
"Don't move…" he ordered Anna in a low voice, staying buried deep inside her as he grabbed both her legs with his arms and lifted her up forcefully.
Anna let out a choked cry but quickly covered her mouth.
With her legs spread wide open and his cock still buried inside her pussy, Hiro carried Anna through the kitchen and down the hallway to the front door, then set her back down on the floor.
Anna turned to look at him with incredulous eyes.
"What are you doing, Hiro?" Her voice was filled with fear and panic.
Hiro let out a low, dark laugh, not pulling even an inch of his thick cock out of Anna's soaked pussy.
"Shhh… open the door, little sis," he whispered against her ear, biting her neck. "And don't you dare make any weird noises."
Anna was shaking violently, her panties still tangled around her knees and her skirt bunched up around her waist. Hiro pushed forward with his hips, forcing her to take an awkward step while his cock sank even deeper. He held her firmly by the hips with one hand and grabbed her hair with the other, yanking her head back to keep her back arched.
The doorbell rang for the third time, even more insistently.
Anna took a deep breath, trying to control her voice, and reached for the doorknob. The exact moment she opened the door, Hiro thrust hard from behind, burying himself to the balls in one brutal stroke.
"Ah…" Anna barely managed to turn the moan into a fake cough.
Standing in front of her was Hatsufuji Akari, the attractive neighbor from next door. A woman in her mid-thirties with short brown hair, a curvy figure, and a kind smile that contrasted sharply with the chaos happening just a meter away.
"Hello, Anna-chan," Akari greeted warmly. "Sorry for coming without notice. Is Hiro-kun home?"
Behind Anna, Hiro began fucking her slowly but deeply. He pulled out almost his entire thick, veiny cock, leaving only the head inside, then drove it back in to the hilt with a sharp snap of his hips. The wet, obscene sound of her dripping pussy was barely masked by Anna's body pressed against the door.
Anna clenched her teeth, her knuckles turning white on the doorframe.
"Y-yes… he's… home…" she managed to say, her voice broken as Hiro fucked her cunt mercilessly from behind. "W-what… ah… can I help you with?"
Akari tilted her head slightly, noticing that Anna seemed a little flushed.
"My husband found out that Hiro-kun is our daughter's private tutor and wants to thank him in person. We were thinking of inviting him to a small informal dinner at our place tonight. Nothing fancy, just the three of us and the girl. Do you think he could come?"
While Akari spoke, Hiro sped up his rhythm. His hips slammed against Anna's bare ass with short, hard strokes, fucking her like an animal. Each thrust made his balls slap against her swollen clit. Anna could feel his thick cock rubbing that sensitive spot inside her over and over, sending jolts of pleasure that made her legs shake.
"H-he… mmh… sure he can…" Anna replied, biting her lower lip so hard she almost drew blood. Her pussy clenched violently around Hiro's cock, juices dripping down her thighs. "I'll… tell him… as soon as I see him…"
Hiro released one hand from her hip and slid it forward, finding her swollen clit. He began rubbing it in fast, precise circles while continuing to fuck her without pause. Anna felt her eyes roll back. She had to lean all her weight against the door to keep from collapsing.
Akari smiled, completely oblivious.
"Great. Tell him to come around seven. Comfortable clothes, it's nothing formal. Oh, and tell him my husband made his famous homemade sake, so he can drink without worry."
"Y-yes… I'll tell him…" Anna moaned almost in a whisper. Her voice sounded dangerously close to breaking.
Hiro, savoring the danger, pulled his cock almost all the way out and then slammed it back in with full force. Anna let out a choked moan that she disguised by pretending she had choked on something.
Akari frowned slightly.
"Are you okay, Anna-chan? You look a bit… strange."
"Y-yes, I'm just… washing the dishes and… I slipped a little…" Anna lied, while Hiro continued hammering her soaked cunt from behind, his swollen cock stretching her to the limit.
"I see. Well, I won't bother you anymore. Thank you!"
Akari said goodbye with a small bow and started walking away down the hallway.
The moment the door began to close, Hiro grabbed Anna by the waist with both hands and started fucking her with savage, rapid thrusts, completely unrestrained.
"Good girl…" he growled against her nape, biting her. "You enjoyed that more than I did, didn't you? After all, you're a slut who loves the thrill of almost getting caught. Now you're going to cum on my cock while you close the door."
Anna barely managed to turn the key before a brutal orgasm ripped through her. Her pussy tightened like a fist around Hiro's cock, gushing abundantly as she moaned uncontrollably.
Hiro kept fucking her mercilessly through her orgasm, prolonging it until Anna's legs nearly gave out.
"Tonight…" Hiro panted without slowing his thrusts, "…I'm going to that dinner. But first… I'm going to fill my big sister's cunt completely."
The door clicked shut.
And Hiro had no intention of pulling his cock out yet.
