Aiko was 23, tight little body from all that yoga and ramen, with straight black hair down to her ass and lips that looked made for wrapping around a dick. She worked at a bar in Shibuya where tourists came in looking for something exotic, and she always gave it to them raw. That night she spotted me at the counter, bought her a drink, and ten minutes later we were in the elevator to her apartment with her hand already squeezing my cock through my jeans.
"Fuck, you're hard already," she said, voice low and direct, no shy bullshit. "I want to suck it. I want to swallow every drop when you cum."
The door barely closed before she dropped to her knees on the tatami. She yanked my pants down and my cock sprang out, thick and veined. Aiko didn't tease.

She opened wide and took the head straight into her hot mouth, tongue swirling once before she pushed deeper. Her throat opened easy, like she'd practiced this. She gagged once, spit running down my shaft, then kept going until her nose pressed against my stomach.
She pulled off just long enough to say, "Cum in my mouth. I love the taste. I want it all." Then she went back to work, bobbing fast, hand twisting at the base while her other hand cupped my balls. Sloppy, wet sounds filled the room. Her eyes watered but she didn't stop. Every few strokes she took me all the way down again, throat squeezing tight around the head.
I grabbed her hair and started fucking her face. She moaned around my cock, the vibration making my balls tighten. "That's it, take it," I told her. "Such a good Japanese slut for swallowing dick." She looked up at me, eyes glassy, and nodded with her mouth full. Spit dripped off her chin onto her small tits, nipples hard under the thin top she still wore.
I didn't last long the first time. I warned her with a grunt and she locked her lips around the head, sucking hard as I pumped thick ropes straight down her throat. She swallowed without pulling off, throat working visibly, then licked the last drops from the tip like she was starving for it. "Mmm, more," she said, wiping her mouth with the back of her hand. "I want you to fuck me and cum in my mouth again."
We moved to her bed. She stripped fast, shaved pussy already wet and glistening. She climbed on top, sank down on my cock in one smooth motion, and started riding hard. Her small ass slapped against my thighs while she reached back to play with my balls. "Fill me up later," she panted. "But first I want another load to swallow."
After a few minutes she slid off, spun around, and took me in her mouth again, tasting her own juices on my shaft. She sucked greedily, one hand between her legs rubbing her clit while she worked. I reached down and fingered her tight hole, two fingers pumping while she moaned around my cock. She came like that, shaking, mouth never leaving my dick.
Round two took longer. I flipped her onto her back, legs over my shoulders, and fucked her deep and rough. She begged for it harder, nails digging into my arms. When I was close again she pushed me out, scrambled down, and opened her mouth wide. "Give it to me," she demanded. I stroked twice and unloaded across her tongue. She showed me the cum pooled there before swallowing it all in one gulp, then sucked the head clean to get every bit.
We lay there catching our breath, but she wasn't done. Her hand stayed on my cock, stroking it back to life. "I can go all night," she said. "Most guys tap out after two, but I want you to use my throat until there's nothing left." She got on all fours, ass up, and looked back at me. "Fuck my pussy first, then pull out and feed me."
I took her from behind, pounding hard enough the bed creaked. Her moans turned into dirty talk in Japanese mixed with English, telling me how much she loved cum, how she wanted it in her belly. When I pulled out she spun and took me deep again. This time she used both hands and her mouth together, working fast and tight until I gave her a third load. She swallowed every spurt, then licked her lips and smiled. "Tastes so good. You're not done yet, are you?"
By the fourth round it was slower but still filthy. She sat on the edge of the bed, head tilted back, and let me fuck her throat while I held her hair. She gagged and drooled but kept her hands on my ass, pulling me deeper. When I came she took it all, swallowing around the head, then milked the shaft with her tongue until I was dry.
Aiko finally collapsed beside me, cum on her chin and a satisfied grin. "Stay the night," she said. "I want breakfast and another swallow before you go." Her hand was already sliding down again, ready for more. That Japanese girl didn't just like swallowing. She lived for it, and she made sure I knew exactly how good it felt to give her what she wanted.
