Hiro no longer had any reason to pretend. He had already crossed the invisible line Anna feared so much, and now he simply reveled in it.
He gripped both of Anna's round, firm ass cheeks with both hands, spreading them slightly for better access, and began pumping his cock in and out of her with slow but deep thrusts—no rush, no hiding. Each stroke was deliberate: he drove in to the hilt, feeling Anna's hot, drenched walls clamp down on him as if they never wanted to let go, then pulled out almost completely, leaving only the thick tip teasing her swollen entrance before plunging back in with controlled force.
The wet, unmistakable sound of flesh slapping against flesh filled the kitchen, barely masked by the residual sizzling of the stove and the faint hum of the exhaust fan. Hiro didn't care. If Rina and Yuria heard… let them hear. But they wouldn't come in. Not yet. That was the game he had designed: to keep Anna in constant terror of being caught, without ever granting her the relief (or the humiliation) of it actually happening.
Anna, meanwhile, plunged into absolute panic.
She clamped both hands over her mouth, pressing so hard her knuckles turned white. Her eyes were wide open, glassy with tears that kept streaming down, desperately staring toward the kitchen doorway. Every time Hiro thrust in, her body jerked involuntarily and a moan tried to escape her throat, but she smothered it against her palms, turning it into a pathetic, choked "mmph… mmph…"
Her knees trembled so violently she could barely stay upright. Hiro had her bent over the counter, her hips pushed back to take him better, her skirt fully hiked up and bunched around her waist, her panties dangling from one ankle. Each thrust made her breasts bounce under her uniform blouse, her hard nipples poking visibly through the thin fabric.
"Shhh… nee-san…" Hiro whispered hoarsely, leaning over her back to speak directly into her ear while he kept fucking her with steady rhythm. "Don't make a sound. If you scream… they'll come. Listen."
From the living room came low, casual voices—clear enough for Anna to hear and for her panic to multiply:
Rina, in a playful tone:
"Mom… do you hear that? It sounds like… rhythmic slapping? Are they kneading something for breakfast?"
Yuria, laughing softly:
"Oh, who knows. Anna has always been so dedicated when she cooks. Maybe Hiro is helping her… mix the ingredients really well."
Footsteps again.
Slow. Deliberate.
Rina rose from the sofa—the creak unmistakable—and walked slowly toward the hallway. She stopped right at the threshold, as always, without entering. This time her shadow stretched a little longer across the kitchen floor, almost reaching where they stood.
Anna froze. Her entire body clenched around Hiro's cock, squeezing him so tightly he let out a low, guttural groan of pleasure. She thought this was it. That Rina would take one more step, peek in, see her: bent over the counter, her little brother's cock buried balls-deep inside her, fucking her mercilessly while she fought not to scream.
But Rina didn't enter.
She just stood there, waiting, as if she knew Anna's terrified silence was more torturous than any answer.
Hiro seized that peak moment of panic to speed up slightly. His thrusts grew deeper, faster, slamming right against that spot inside Anna that made stars explode behind her eyelids. She shook her head frantically, tears splashing onto the counter, hands crushed against her mouth as if her life depended on not letting a single sound escape.
"Look at them," Hiro whispered, one hand sliding up to grab one of her breasts over the blouse, pinching the hard nipple sharply. "They're two steps away. All they have to do is lean in a little more… and they'll see you. See you getting fucked by your little brother while you 'make breakfast.' See you breaking. Do you want that, nee-san? Do you want them to walk in and watch you cum all over my cock?"
Anna shook her head again, but her pussy told the truth: it spasmed violently around him, gushing more with every thrust, slicking everything until the wet slapping sound was impossible to ignore.
Hiro felt her teetering on the edge. She was seconds from coming undone—but he wasn't going to let her. Not yet.
He suddenly slowed, pulling out almost completely and holding still with just the tip inside, leaving her empty and aching.
Anna let out a strangled sob against her hands, her hips bucking backward on their own, silently begging him to fill her again.
"Say 'please,'" Hiro ordered in a low voice. "Say 'please don't stop.' Or… say 'stop' and I'll pull out for good. Your choice."
Anna shook violently. Tears, sweat, her own fluids running down her thighs. She looked toward the doorway, where Rina's shadow still lingered, motionless, waiting.
And then, in a broken voice, barely audible through her fingers:
"P-please… don't stop…"
Hiro smiled.
He slammed back in with one deep, punishing thrust, and this time he held nothing back. He fucked her hard but controlled, keeping Anna's moans right on the edge of audible—just enough for Rina and Yuria to hear "strange noises," but not enough for them to barge in.
From the living room, Rina let out a soft giggle.
"I think Anna is… really focused today."
Yuria replied in a syrupy tone:
"Let her be. Breakfast is going to be… unforgettable."
Anna squeezed her eyes shut, bit her hands until fresh blood welled up, and surrendered to the pleasure and terror.
She knew they could catch her at any second.
But they didn't.
And that… that was driving her completely insane.
Hiro glanced over her shoulder and caught Yuria and Rina's eyes. He flashed them a huge grin.
He gave them a thumbs-up and sped up his thrusts without a shred of concern.
CLAP CLAP CLAP CLAP
The loud, unmistakable sounds of flesh slapping flesh echoed clearly through the kitchen and into the living room, mingling with Anna's choked, desperate whimpers.
