As the door slid closed behind me, Kazuko led me around the screens to her mat.
The same servant girl was sitting in the middle of it, blindfolded, her hands tied behind her back with a thin silk tie.
"Okay, the time has come," Kazuko said quietly but firmly, removing the blindfold. The girl gasped, her eyes narrowing in fear at the sight of my mask. "Are you scared of the playful Kappa?" Kazuko asked with a mocking concern. She sneered. "You'll do whatever Kappa or I want, wretch."
She grabbed the shivering girl by the throat. "Do you understand?"
"Yes, mistress," muttered the girl.
With one hand still on the girl's throat, Kazuko slid two fingers of the other hand into the girl's mouth. She pressed her tongue down and pushed deeper. The girl gagged slightly, but Kazuko didn't flinch, holding her fingers firmly in place.
The girl's eyes watered and her face reddened from the intrusion. With a satisfied nod, Kazuko started thrusting her fingers deeper at a slow, rhythmic pace. Wet noises of her fingers sliding in and out muffled the girl's gasps.
"What do you think, Kappa?" Kazuko asked, turning to me with a smile. "Wet enough?" She didn't wait for me to reply. "I think she requires more moisture. I see Kappa is salivating already."
Kazuko pulled her fingers up to the entrance of the girl's mouth and pushed them far apart, holding the mouth wide open.
She waited for me to lean over and drop a large gob of saliva into the girl's mouth. She pushed the girl's chin up, watching my spit sliding inside.
"That's what we needed," she murmured, pushing her fingers back into the girl's mouth, thrusting my spit down her throat. "Now it's nice and slippery for you, Kappa."
The girl gagged again, but Kazuko shook her hard with both hands. "Hold it!"
Kazuko pulled her hand out of the girl's mouth and used it to open my kimono.
"Kappa is excited," she noted, rubbing the girl's slop off her fingers on my erect cock. "Go ahead, Kappa. Put it where it belongs."
She prodded me forward and pushed the girl's mouth onto my cock. "Yum," Kazuko whispered in my ear, teasing it with her tongue. The girl was gagging on my cock in the meantime, Kazuko's hand still firmly wrapped around her neck.
"You're spilling it!" exclaimed Kazuko when some saliva dropped out of the girl's mouth onto the futon. "We should add it back." Kazuko extracted my cock from the girl's mouth and spit on the tip of my cock. "There," she muttered and inserted it back into the girl's mouth, pushing her face right up to my balls. The girl gagged again, trying to move back, but Kazuko's hold was iron-clad. She watched tears streaming down the whining girl's face for a few moments before releasing her grip. The girl jerked back, catching her breath.
"Such a drama queen," chuckled Kazuko, pushing the girl down and untying the girl's hands. "Let me punish her for that."
She picked up the same strap-on harigata she used last time and spit on it. She attached it to her waist and then delivered two heavy blows to the girl's butt.
"Get your ass up from the futon!" she ordered.
When the girl propped her butt up, Kazuko spit between her butt cheeks and positioned the harigata at the rear entrance.
"Go!" she commanded herself and pushed the harigata in.
Overcoming the girl's resistance, she inserted most of the length in and glanced back at me. "I want you inside me, Kappa," she said, her nostrils flaring.
She slipped out of her kimono and guided my cock into her pussy from behind.
I leaned forward, thrusting into Kazuko, making her, in turn, thrust into the girl crouched before us. The three of us moved in tandem for a while, Kazuko's hand reaching back and running through my hair. Kazuko moaned and wriggled her body trying to maximize her pleasure from both receiving and delivering thrusts.
"Your cock is driving me insane!" she whispered frantically in my ear. "Harder!"
I thrust harder to the rhythmic sound of Kazuko's hips smacking against the girl's buttocks. Kazuko's pussy started to slosh and clench my cock as she shuddered, pausing her own thrusting.
"Oh, how I wish my flower could take many hours of your torment," she murmured. She gazed deep into my eyes, her eyelids fluttering, half-closed in pleasure. "I melt every time you're inside me… I wish you could be inside me every day… all day…"
Kazuko kissed me deeply, swirling her tongue around mine and sucking in as much of my saliva as she could.
"But I have to make sure you get to cum," she smiled. "We could still share."
She switched her strap-on for a thicker harigata. Then she lay on her back and commanded the girl to get on top. "Now put it inside," Kazuko told her. The girl slowly lowered herself, impaling her pussy with moaning and grunting onto the thick harigata.
"There's a good slut!" chuckled Kazukol, slapping the girl's thigh. "Now, lean forward to let Kappa join in!"
The girl obeyed, sobbing quietly, and I started to push my cock into her ass. It was harder this time, with her pussy stretched by harigata. My cock struggled to make enough room, and the girl whined loudly as both Kazuko and I tried to thrust at the same time.
"It's ripping me apart," she muttered. Suddenly, she cried out as Kazuko pinched her nipples.
"Shut up!" Kazuko barked. "You are here for us to share as we please, not to talk!"
The girl tried to swallow her sobs, her body twitching from double penetration.
Kazuko looked at me, smiling. "Do you enjoy our toy, Kappa?"
"Yes," I grunted.
"Is Kappa close?" Kazuko chuckled. She reached with her hand to tease my balls as I was finally able to fit my entire length into the girl's rear.
"Yes…"
"Well, then let's do it together," she said, pressing on my balls and grabbing the girl's clit with the other hand.
"Heavens!" hollered the girl, shaking from head to toe.
It felt to me like her ass vibrated, the girl's loud sounds mixing with harigata's jerky pressure again the inner wall. I couldn't hold back any longer.
I growled, releasing loads of hot cum into the girl's insides. Kazuko joined in with a moan, and our three voices merged into a raunchy cacophony.
"Is Kappa satisfied?" Kazuko asked, panting, when I pulled out and slid on the mat.
"I am," I groaned.
She pushed the girl off and turned to the side. There was a light dew on her forehead from all the exertion and her carefully styled hair was now tousled. But she glowed with utter bliss. "I hope to be able to satisfy Kappa more often," Kazuko said.
She kissed and hugged me as I was thinking about how much time I'd need to gather enough strength to get back to my room.
