MIOKO
We’d been in New York for five days, and I was starting to find a rhythm.
Mornings, Daniel-san would go to his office – he was a computer engineer who designed digital games. I didn’t fully understand too much because I never played any electronic games. Kioko and I would spend the day exploring the neighborhood, practicing our English at shops and cafes, learning to navigate the subway system.
It was overwhelming but exciting. Everything was so different – the language, the food, the way people dressed and acted. New Yorkers walked fast and talked loud and seemed to be in a perpetual hurry.
But slowly, I was adjusting.
At night, Daniel-san would come home and we’d have dinner together – sometimes Kioko cooked Japanese food to ease our homesickness, sometimes we ordered American takeout to try new things.
And then Daniel-san and I would retreat to the bedroom, and he would make love to me.
Each time was easier than the last. My body was adjusting to his size, the pain had faded to a pleasant soreness, and I was learning what I liked – what angles felt best, what rhythm made me cum hardest.
But there was still one thing we hadn’t done.
One promise still unfulfilled.
My anal virginity.
I’d been waiting for him to bring it up, but he seemed content to let me adjust to regular sex first.
Tonight, as we lay in bed after he’d made me cum twice, I decided to broach the subject.
“Master?”
“Mm?” He was running his fingers through my hair, both of us sated and relaxed.
“When are you going to ... I mean, we talked about ... in Japan, you said...”
I was stumbling over my words, embarrassed.
He chuckled. “Are you asking when I’m going to fuck your ass, Princess?”
My face went hot. “Hai, Master.”
“I was waiting for you to be ready. For your pussy to fully heal from losing your virginity. But if you’re asking...” He rolled over to look at me, his blue eyes intense. “Are you ready?”
Was I?
I thought about the times he’d fingered my ass – first during the back massage in Japan, then again during the front massage. How I’d loved the fullness, the intensity, the way it had made me cum so hard I’d seen stars.
But his finger was tiny compared to his cock.
Still, I’d promised myself to him completely. And I wanted this – wanted to give him every part of me.
“Hai, Master. I’m ready.”
He smiled and kissed me gently. “Tomorrow night, then. After dinner. I’ll prepare you properly, and we’ll complete your claiming in our new home, just as I promised.”
Tomorrow night.
My stomach did a nervous flip.
DANIEL
The next day at work, I could barely concentrate.
Tonight, I would take Mioko’s last virginity. Complete my ownership of her body in every way.
I left the office early and stopped at a specialty shop to pick up supplies – high-quality lubricant, latex gloves, and a small training plug set I’d ordered online.
When I got home, Kioko was in the kitchen preparing dinner, and Mioko was curled up on the couch reading a book in Japanese.
She looked up when I entered, and I saw the nervousness in her eyes.
She knew what tonight was.
“Good evening, Master,” she said softly.
“Good evening, Princess. How was your day?”
“Good. Kioko and I went to Central Park. It’s beautiful.”
“I’m glad you’re exploring the city.”
We made small talk while Kioko finished cooking, and then the three of us sat down to a traditional Japanese dinner – grilled salmon, miso soup, rice, pickled vegetables.
The food was excellent, but I barely tasted it. My mind was already on what came after.
When we’d finished, Kioko began clearing the dishes.
I stood and offered my hand to Mioko. “Come, Little One. It’s time.”
She placed her small hand in mine, and I led her to the bedroom.
MIOKO
Daniel-san closed the bedroom door behind us, and suddenly the reality of what was about to happen hit me.
He’s going to put his cock in my ass. That massive thing is going inside me back there.
My breathing quickened.
“Mioko.” His voice was firm. “Look at me.”
I raised my eyes to his.
“We’re going to take this slowly. Very slowly. I’m going to prepare you thoroughly, and I won’t proceed until you’re ready. If at any point it’s too much, you use your safeword. Understood?”
“Hai, Master.” My voice came out as a squeak.
He smiled gently. “What’s your safeword?”
“Red, Master.”
“Good girl. Now, undress for me.”
With shaking hands, I pulled off my clothes until I stood naked before him, wearing only my collar.
“On the bed, on your hands and knees.”
I climbed onto the bed and assumed the position, my ass in the air, feeling incredibly exposed and vulnerable.
I heard him moving around behind me – the sound of a bottle opening, latex snapping as he put on gloves.
“I’m going to start with one finger,” he said calmly. “Just relax and breathe.”
I felt cool lubricant being drizzled directly onto my asshole, and I jumped at the sensation.
“Easy, Princess.”
Then I felt his finger at my entrance – not pushing in yet, just circling, massaging, getting me used to the sensation.
“How does that feel?”
“Weird. But ... not bad.”
“Good. Now I’m going to push in. Bear down like you’re going to the bathroom – it helps.”
I did as he said, and felt his finger slip inside.
The sensation was strange – full, intrusive, but not painful.
“That’s it. You’re doing great.”
He moved his finger in and out slowly, letting me adjust, and gradually the strangeness faded into something almost pleasant.
“I’m going to add more lube and a second finger now.”
More cold lubricant, and then the stretch as he worked a second finger inside.
This was more intense – fuller, tighter.
“Breathe, Mioko. Don’t clench. Relax into it.”
I forced myself to breathe slowly, and after a moment, my body accepted the intrusion.
He worked both fingers in and out, scissoring them gently to stretch me.
“You’re doing beautifully, Princess. I’m very proud of you.”
Despite my nervousness, I felt a surge of pleasure at his praise.
