Kameko and I feel asleep in each other's arms after our marathon sex session and by the time we woke up I had missed my flight. I was kind of annoyed. I mean, the sex was amazing, but it wasn't really fair of her to show up at my door on the day I was leaving and fuck my brains out until I decided to stay. Of course, that is pretty much what ended up happening.
"So does this mean you're going to tell your parents about us?" I asked.
"No. It will have to remain our secret," said Kameko, her eyes downcast in shame.
Her insistence that we kept our relationship a secret was frustrating but I didn't really have a good reason for feeling that way. It's not like I really wanted to spend time with her parents or something. I mean, from the photos I had seen her mom looked pretty attractive. She kind of reminded me of Mrs Hashira, but her dad looked like a real hard ass. I had also been keeping lots of secrets from Kameko so it would have been hypocritical if I had complained too much.
"And what about the money I just lost on my plane ticket?"
"I'll pay for it," she said, "that's why we won't tell my parents, so I can keep my allowance and spend it on you."
"What about work? I already quit my job..."
"You don't have to work anymore," she explained, "I will pay for everything."
"And my apartment? I've terminated my lease."
"You can stay with me."
She could tell that I was undecided. It was a generous offer but being free to explore the city and have my own experiences had been one of the best parts of my life in Tokyo. I told her that I was not sure I was ready for such a commitment with someone who couldn't even tell their parents about me and that I enjoyed being free to work and explore Tokyo on my own.
"I'll make it up to you," she said, toying with a strand of hair.
We were still in bed and Kameko was propped up on a pile of pillows beside me. Her long black hair hung down and covered her breasts, contrasting with her porcelain skin, and I couldn't help admiring her unique beauty as she tried to convince me to stay in Japan.
"I'm not sure..."
"Please!" she begged, "I want you to stay!"
"How do you plan on making it up to me?" I asked, curious as to what she had in mind.
Kameko put her hand beneath her chin as she pondered her answer in the most adorable way. She was definitely trying to look cute to seduce me, but I needed some concrete promises.
"You can have sex with other girls," she blurted out as though she had just had a brainwave.
Things were starting to get interesting.
"Seriously?"
"Of course. I would do anything to make you happy. I will arrange everything. You know I have many attractive friends."
I thought back to some of the girls she had been with at the Raman shop the night I met her and realized it was true, Kameko did have several hot friends. I had really liked a girl named Kita who laughed at all my jokes and spoke very good English. But I still wasn't sure if Kameko was being serious or if she was just luring me into staying with empty promises.
"What about Kita, would you let me sleep with her?"
Kameko frowned.
"Oh my god, Kita is too pretty, that would make me too jealous!"
"Is that a yes or a no?"
Kameko was silent for a moment.
"It's a yes," she concluded eventually, "but only if we do it together."
That sounded reasonable enough. The negotiations were going pretty well and I suddenly wasn't so angry about missing my flight anymore. But I wasn't done yet. Staying with Kameko would still mean giving up many of the sexual freedoms I had grown accustomed too.
"What else would you do to convince me to stay?"
"I will cook you delicious meals every night and give foot massage!"
"Okay, anything else?"
Kameko thought hard about how she might seal the deal. She was clearly enjoying submitting to me and the strange paradoxical power it might ultimately give her.
"Let me show you," she said, climbing out of bed and kneeling, naked, on the floor. "My ass," she explained, spreading her cheeks just like the girls in Dr Kahira's experiment, "You can put it in my ass any time you want to. It is so tight. I am sure you will like it. You want to try?"
That sealed the deal.
My penis was already fully erect from the conversation we were having and the sight of Kameko kneeling on the ground with her ass in the air, made my cock throb. I jumped out of bed and put a pillow under my knees as I knelt behind her.
"Please be gentle," she begged.
I spat onto my hand and coated my cockhead for lubrication and then without further hesitation I began slowly forcing myself into Kameko's waiting ass. She seemed nervous. It was clear she hadn't done this before and her asshole was tight. But that just made the sensation even better as I gently eased the tip of my cockhead into her usually off-limits orifice.
I actually needed to piss, which made my erection even harder than usual and the pressure on my bladder added a strange additional dimension of pleasure to the experience. Kameko tried not to react, but when I finally managed to forced the first full inch of my swollen cock inside her she yelped and her legs started trembling.
"It is so big!" she cried.
"Do you want me to stop?" I asked.
"No. I want you to stay in Tokyo," she said, "Please fuck me in the ass..."
I didn't need a second invitation. I started rocking my hips back and forth, very slowly, easing her open with my cockhead. Two inches disappeared into her hot opening, then three, another little yelp escaped her lips, then four, a loud moan, then five...
After a blissful few minutes of squeezing my dick into the tightest hole it had ever entered I finally plunged my entire cock into her virgin asshole and Kameko shook with her first anal orgasm. She was resting her head on the floor and moaning incoherently by this point with saliva escaping from the corners of her mouth. Her ass was nicely stretched open then so I increased my tempo and started to really fuck her.
"Yes, fuck my ass!" she screamed as I slammed my cock up her backside, "Cum in my tiny asshole. Make me your anal slut! Cum in my bum!"
Kameko's dirty talk made me extremely horny and I relentlessly pounded her rear end. It took a while for her to get used to my size, but once her body had adjusted, my dick slid in and out of her asshole with ease. Her ass was definitely tighter than her pussy, but it was still receptive to penetration and I went wild after weeks of being teased and jerked off by Nurse Yamadori.
Kameko was delirious with pleasure, cumming repeatedly from the anal penetration, while all the sexual experiences from my year in Japan flashed before my eyes. My heart was pounding faster than my cock could keep up and my balls slapped against Kameko's flooding vagina as I gripped her wide hips and demolished her receptive anus.
"I going to cum," I explained, breathlessly, and oddly politely, considering the situation.
Kameko was far less reserved. Strands of dark hair clung with sweat to her back and face and she practically screamed her reply as another serious of overlapping climaxes rippled through her submissive body.
"Yes, Max! Please fill my asshole with your foreign sperm! I love you!"
I came so hard I felt like I was going to make a baby in her butthole. Stars exploded across my vision and my balls ached as they expelled an unprecedented volume of freshly brewed spunk into the darkest depths of Kameko's bottom.
My dick stayed hard and a loads of cum oozed out of my girlfriend's anus as I slowly pulled out. Her beautiful asshole expanded and contracted as it tried to recover. Rivers of semen ran down her inner thighs until a veritable lake of cum pooled between her feet on the floor.
"Thank you," she said as she started to cry.

The next day we moved in together. Thanks to her parents generosity, Kameko's place was way better than mine so I had nothing to complain about, but I was still acting as though she owed me something in the hope that she would let me take her up the bum again. Kameko was true to her word and refunded me the full fare for my unused airline ticket, but all I could think about at that point was her impossibly tight asshole.
She cooked me dinner that night, just as she promised, a bowl of Raman with noodles as a nod to the night we met, and she gave me a long foot massage after dinner. I should have felt guilty about making Kameko do all this stuff for me, especially considering the fact that I was the one who cheated on her, but to be honest, she seemed to enjoy it. I think for a spoilt little rich girl it was a joy to finally have someone to serve.
I really wanted to have sex but Kameko said her ass and pussy were still sore from the previous day, so she offered to give me a blowjob instead. I agreed and lay down on the bed. She seemed just as excited to suck my cock as the first night we slept together, though she sucked me with a degree of care now that could only be given to someone you truly loved.
Her tongue moved excruciatingly slowly as it circumnavigated my cockhead and she looked me in the eyes the entire time. Her dark eyes and natural long lashes mesmerized me and I felt like I was in the presence of an oriental queen. Reaching my full size, Kameko took me in her mouth, trying to see how far she could take my dick down her throat before she started gagging. She got almost all the way to the base before coming up for air, eyes watering, but triumphant.
