Yuria had been restless from the very moment Hiro came down to dinner that night.
From the second she saw him walk into the dining room wearing that tight t-shirt that hugged every roll of fat, from the moment she watched him sit down and look at his sisters with an intensity he had never shown before, something inside her understood.
Hiro had changed!
When Hiro went to his room after dinner, Yuria couldn't sleep.
She stayed awake, tossing and turning in bed, feeling her pussy throb just remembering the way Hiro had hugged her goodbye that morning—the bulge in his pants pressing against her thigh, the way his hands lingered one second too long on her ass cheeks.
And then she heard voices.
Low voices, but clear. They were coming from Rina's room.
Yuria got up silently, stepped into the hallway and approached her youngest daughter's half-open door.
And she saw everything from the beginning.
She saw Hiro show Rina the cosplay photo. She saw Rina go pale and let him in. She saw her son grab one of her daughter's tits without permission. She saw the forced kiss, the spanking, the low-voiced orders. She saw Rina trembling as she obeyed, taking off her blouse, letting him grope her breasts. She saw Hiro put her on all fours and spank her, alternating cheeks with cruel calm.
And every slap, every "Yes, sir", every muffled moan from Rina hit Yuria like a direct punch between her legs.
She didn't leave.
She stayed there, glued to the door, one hand already inside her pajama bottoms, slowly touching herself while she watched her son dominate her youngest daughter.
When Hiro left, leaving Rina alone and desperately horny, Yuria still didn't move.
She listened to Rina's panting as she masturbated. She heard her daughter moaning Hiro's name between gasps: "Ahhh… Hiro…! Anmnnn!"
And that was the trigger.
Yuria slipped back to her own bedroom right next to Hiro's and locked the door.
She sat on the bed, lifted her nightgown and pulled her panties down.
She shoved three fingers inside herself at once while imagining it was her on her knees in front of Hiro.
She imagined it was her being blackmailed!
She pictured his hands lustfully roaming every inch of her body and imagined being defiled by his cock.
That day she had an orgasm after a month of drought.
But it wasn't enough.
She needed to see it again.
The next day, after Hiro came back from school radiating that new confidence, after he'd gone to give Shizuku lessons and returned whistling like he owned the world, Yuria made a decision.
While Hiro was in the shower that night, Yuria silently entered his room.
She went straight to his dirty laundry drawer and began sniffing deeply. The pure male scent alone turned her on, but that wasn't why she came.
She wanted the photos Hiro had taken; she wanted to see again what happened that night and relive it.
And there it was.
A small, round, freshly made hole. He had probably drilled it that very afternoon after coming back from school, when no one was watching.
Yuria felt a shiver of excitement as she touched the edge of the hole. It was clean, freshly opened, as if her son had planned this in advance.
And she looked through.
The view was perfect: her bed, the dim lamp, the closed door.
Then she understood!
Hiro had made a peephole into her room to spy on her.
The idea, instead of frightening her or maybe angering her, only made her pussy gush with arousal.
Hiro wanted to watch her horny body!!
When she realized this, Yuria stopped looking for the photos. If Hiro wanted to spy on her through that hole… then she would give him one hell of a show.
But in the end, the one who ended up witnessing one hell of a show was her.
She peeked through the hole with her lights off so Hiro wouldn't notice her. She wanted to see if he was already in his room, just so she could give him something really good.
But what she saw stunned her…
She watched Hiro push Rina against the wall and start groping and sucking her tits.
She saw his hands roaming all over her body with zero resistance from Rina.
But what left her completely breathless was when Hiro pulled his pants down and unleashed that monstrous cock.
His dick was long and extremely thick—so much so that Yuria swallowed hard. She imagined that monster invading her mouth the same way it was currently invading her youngest daughter's mouth.
When Hiro dragged Rina closer to the peephole, she felt her heart pounding like crazy.
Hearing her daughter's pleas and moans set her on fire completely and she began masturbating furiously while watching.
She felt no repulsion.
She felt no maternal guilt.
Only an overwhelming heat that consumed her.
When Hiro penetrated Rina mercilessly and pulled his cock out soaked in fluids and blood, Yuria came hard.
Watching her youngest daughter lose her virginity awakened something inside her. Something that had been asleep for a very long time.
Even after he had already cum, she kept watching until the very end while pumping her fingers in and out of her cunt.
She felt she couldn't tame the beast inside her. Especially after seeing Hiro brutally fuck her daughter's pussy while yanking her by the hair.
When it was all over, Yuria felt an emptiness inside. She wanted Hiro to keep fucking Rina, to barge into her room uninvited and force her to swallow his long, thick cock.
Lost in her thoughts, her phone buzzed with a message.
When she picked it up and saw the photo—Hiro's cock nestled right between Rina's ass cheeks—the panic consumed her.
Hiro knew they were being watched!!
Hiro knows I'm a pervert!!
Her face went pale and terror took over. She knew her beautiful family life was over forever.
But as the seconds passed she began to understand things better.
Hiro knew she was watching… and he said nothing. He let her see everything and even moved closer so she could get a better view.
Hiro knows she's a pervert… and instead of disgust or rejection, he sent her a message sharing his conquest.
Yuria started biting her lip as her thighs became drenched with fresh arousal.
She picked up her phone and, after hesitating a moment, replied.
"I saw everything 🤤."
After thinking a little more, she sent another message:
"Remember to wash your cock properly afterwards 🥰."
Just like the caring mother she really was.
