Hiro didn't stop his piston-like thrusting into Rina's mouth, but she seemed to be getting more and more used to it.
In fact, she was starting to really enjoy it—especially judging by the small puddle forming between her legs.
Hiro released Rina's head, but just as he suspected, the perverted girl didn't pull away. She kept sucking his cock with the same speed and intensity.
Hiro tilted his head back, placed his hands behind his neck, and looked toward the hole in the wall with a huge grin.
As if showing Yuria just how much of a slut her daughter really was.
Hiro simply didn't want to forget this moment, so he grabbed his phone and started recording the gorgeous, big-titted blonde who was eagerly sucking him off.
Hiro held the phone steady with one hand. The framing was perfect: Rina's flushed face, her swollen lips stretched wide around his thickness, tears of effort gathering at the corners of her eyes, and below that, the constant motion of her throat as she swallowed him deeper each time.
"Fuck… you suck it so good, Rina," Hiro murmured, more for the camera than for her. "Look at how much you're drooling… you look like a pro whore."
Rina let out a muffled moan that vibrated straight through his cock. She didn't reply with words; she just sped up, sucking harder, letting saliva drip down her chin and splatter onto her bare tits. The puddle between her knees was undeniable now—her sleep shorts were soaked dark at the crotch, and a shiny trail ran down the inside of her thigh.
Hiro felt his orgasm starting to climb up his spine, but he still didn't want to finish. He wanted to drag out the show. He wanted Yuria on the other side to squirm with desire, jealousy, or whatever twisted feeling that horny stepmother was experiencing while watching her daughter willingly deepthroat her stepbrother's cock.
Hiro gave a wicked smile toward the darkness on the other side of the hole.
*You seeing this, Yuria?* he thought to himself, almost as if speaking directly to her. *Your little girl is on her knees here, taking it all the way down her throat. And I'm not even forcing her…*
Rina pulled off for a second, gasping, thick strands of saliva connecting her lips to the tip, but she immediately dove back in, as if she couldn't stand being without it for even a moment.
Hiro let out a dark chuckle and refocused the camera on her.
"Good girl. Keep going… let your mom see what a real slut you are."
He grabbed her hair again—this time harder—and started fucking her mouth with short, brutal thrusts. Rina moaned loudly, hands gripping Hiro's thighs, but she didn't pull back. Instead, she pushed her head forward, trying to take him even deeper.
The wet, obscene sound filled the room: gluck-gluck-gluck every time the tip hit the back of her throat.
Hiro knew he couldn't hold back anymore.
"I'm gonna cum…" he growled. "Where do you want it, huh? On your face? In your mouth? Or do you want to swallow every drop like the whore you are?"
Rina answered by tightening her lips even more and swirling her tongue faster around the head, as if the question didn't even deserve an answer—she wanted it all inside.
Hiro let out a guttural groan, thrust one last time to the hilt, and held there, unloading straight down her throat. Wave after wave. Rina swallowed convulsively, eyes squeezed shut, tears streaming down her cheeks, but she didn't let go even a millimeter.
When he finished, Hiro slowly pulled out of her mouth. One last thick strand of cum and saliva hung from her lower lip before snapping and falling onto her chest.
She panted, mouth open, tongue still out as if begging for more. Hiro aimed the camera one final time, capturing the image: Rina on her knees, face and tits smeared, eyes glassy and lost in pure bliss.
"Smile for the camera, little sis," he said in a low, mocking voice. "This is gonna be our little secret… or maybe not so secret."
He stopped the recording and set the phone on the bed.
He glanced sideways at the hole.
The red exclamation mark was still there, unmoving, but Hiro could swear the darkness on the other side had grown thicker, as if someone was holding their breath.
As if the person on the other side was anxiously waiting for what came next.
He looked down at Rina, still on her knees, licking her lips.
"First, let's see how much more this little slut can take before I get hard again."
He grabbed Rina by the nape with gentle but firm pressure and lifted her off the floor.
"Take off those soaked shorts," he ordered. "We're not done yet."
Rina, trembling with excitement, obeyed without hesitation.
Slowly she slid the shorts down and smiled at Hiro as she did it. Her two massive, voluptuous globes of flesh jiggled into full view.
Hiro's cock couldn't take it anymore—it sprang back up, rock-hard and ready.
Hiro raised his hand and delivered a hard slap right across her ass.
"Ahhhhh!!"
Rina's already dripping pussy gushed even more, as if the impact alone had made her cum again.
Hiro was using everything he knew about Rina to his advantage. He knew she fantasized about being blackmailed, that she was a total masochist, and that she loved being dominated without mercy.
So he had no qualms about how he treated her—she was the perfect example of a flesh toy made to be used.
Hiro grabbed Rina by the nape again and slowly guided her closer to the hole. He made her bend into a formal Japanese apology position (dogeza): forehead almost touching the floor, arms stretched forward, ass high in the air. In that pose, her round, fat cheeks, her swollen virgin pussy, and even her tiny pink asshole were perfectly exposed and aimed straight at the hole in the wall.
In that humiliating position, Hiro stepped up behind her and gave her another brutal slap on the ass, making the flesh ripple and leave an immediate red handprint.
"Ahhhhh!"
Rina panted like an animal in heat, her massive tits hanging heavy and bouncing with every ragged breath. Her nipples were hard as diamonds, large and pink, surrounded by wide areolas that puckered from pure arousal. Sweat beaded on her pale skin, making it glisten under the dim light, and her long blonde hair stuck to her flushed face and swaying breasts.
"Hiro… please…" she begged in a hoarse voice, nails digging into her own thighs to spread herself even wider. "Put it in… break my virgin pussy… make me your whore already… I've been dreaming about this for years…"
