"Say, that's a neat trick! How did you even learn all that, anyway?"
"Ehehe, you learn a lot when you're a volunteer! I've been with so many of the girls that I've been able to try out all sorts of things with them. My favorite are the shy girls. It's so funny how flustered and embarrassed they all are, but they still want to get their little dicks sucked and are just too afraid to ask."
"I hope you don't tease them too much!"
I-19 and Shiratsuyu both shared a laugh as the two of them walked and talked in the halls of the admin building, with Iku still dripping water from her last mission. Shiratsuyu had bumped into her as she went and had gotten to talking with her about their experiences.
"What kind of futa girls do you like, Shiratsuyu-chan? The ones with small dicks or normal dicks? Or maybe the bigger girls? I heard the cruisers and battleships only like to have sex with other girls of their types because us subs and the destroyers have shallower pussies" Iku said.
"Ehhh? That can't be true. I think every girl is the same depth. But, as for me, I like average sized futas. I don't like to do oral, so vaginal is number one for Number One!" Shiratsuyu said.
"Man you don't know what you're missing! It's so much fun to suck a girl dry and watch her face. A lot of them make funny faces when they're getting sucked off, especially when they're about to cum! You should try it sometime! I promise it doesn't taste that bad, but the texture's kinda weird, all warm and slimy."
"Ewww. No thanks, I'll stick to vaginal. Handjobs are OK, too!"
"You're no fun. Well, bye Shiratsuyu-chan. I gotta go report to Nagato, and 'report' to the Admiral" Iku said with a wink, and took off.
"Byeee!"
By herself now Shiratsuyu smiled and headed off for the bathrooms. There were some not far from the Admiral's office, just around the corner, and Shiratsuyu strolled right to them, humming as she went. She pushed the bathroom's door open and was surprised to see Yuudachi standing by one of the onaholes, naked from the waist down.
"Uwa! Sorry, didn't mean to walk in on you, Yuudachi-nee. Do you need help?" Shiratsuyu said, and Yuudachi smiled at her.
"Hi, Shiratsuyu! These things are, like, OK, but doing it with another girl is a lot more fun-poi Can we do it, Shiratsuyu-poi? There's a breakroom nearby that should be a lot more comfortable" Yuudachi said.
"Sure! Just leave it to Number One!"
Yuudachi scooped up her skirt and underwear but didn't bother to put them as the two of them left the bathroom and walked down the hall to the breakroom, Yuudachi's stiff cock bobbing as she walked. They entered the breakroom, and Yuudachi threw her bottoms on the nearest couch and took Shiratsuyu's hands into her own. "Thanks for, like, helping me out with this, Shiratsuyu."
"No problem! Wanna take this fast, or slow?" Shiratsuyu asked.
Yuudachi hummed and put a finger to her chin. "Actually I, like, want a paizuri from you. Is that OK?"
"A...paizuri? Like, between my boobs?"
"Poi!"
Shiratsuyu thought about it a moment. "I've never tried anything like that. It's gonna be all messy. I don't want any of your spunk in my mouth, got it?"
"Mm! Just don't open your mouth and it'll, like, just get on your neck and face-poi. If you don't want to, that's OK, but it'd be super hot-poi" Yuudachi said. She shook her fists and her hips, and her cock bobbed again. Shiratsuyu pictured it thrusting back and forth between her boobs, leaving little trails of precum, and licked her lips.
"Alright, let's do it. Let's just find some lube real quick" she said, and walked over to a couch that had end tables on either side. She opened up one and started rooting through when she felt one of Yuudachi's hands press to her side and start stroking.
"You're super pretty, Shiratsuyu" Yuudachi said, and Shiratsuyu smiled. After a few moments she found a bottle of lube and set it on the table. She turned around, put her hands on Yuudachi's hips, and gave her a quick kiss.
"Ready?" Shiratsuyu asked, and Yuudachi nodded. Shiratsuyu pulled off her shirt and released her bra. Her boobs dropped free with a bounce and Yuudachi stared at them. Shiratsuyu sat down on the couch and poured some of the lube on Yuudachi's cock, used a hand to slather it on, and poured a little bit into her cleavage. She shimmied around on the couch until she was comfortable and looked up at Yuudachi. "Have at it!"
Yuudachi grinned and got on the couch, straddling Shiratsuyu. She slid her cock between Shiratsuyu's breasts and Shiratsuyu was about to reach up and press them together when Yuudachi stopped her. "Let me. That way you can rub off while I do it."
"Sure~" Shiratsuyu said, and spread her legs a bit. With a little fiddling she was able to get her panties down to her knees, which was good enough. Yuudachi grasped her breasts, squeezed them together, and started thrusting.
"Ppoooii, there we go" Yuudachi said, her cock gliding back and forth between Shiratsuyu's plump boobs. Shiratsuyu let out a sigh, her fingers gently stroking her pussy and clit in wide circles. She looked up at Yuudachi, who had her eyes closed. Yuudachi was using her thumbs to rub Shiratsuyu's nipples, which Shiratsuyu found pleasant.
"Having fun? Everything feeling good?" Shiratsuyu asked, and Yuudachi nodded.
"It's, like, so warm and slick, I love it. You have such nice boobs, Shiratsuyu."
"Heh, thanks. Lots of futa girls really like 'em. They say they're perfectly plump and round, and like how my nipples are a little upturned. Pert and perky, that's me!" Shiratsuyu said, and Yuudachi smiled.
"Just the way I like it, too" she said with a blissful sigh. Shiratsuyu looked back to Yuudachi's cock and saw a little bead of precum get smeared across her breasts as Yuudachi pushed back through. Yuudachi pulled back and her cock disappeared, reappeared when she thrusted back forward, and disappeared again. She could even feel Yuudachi's little balls dragging back and forth across her tummy.
"This is kinda fun. Different. I think I like it" Shiratsuyu said, and Yuudachi hummed.
"That's nice, I'm like super glad."
Shiratsuyu focused back on stroking her pussy, pressing her fingers firmer against it. She spread her lips open and shut, open and shut, open and shut. The stretching sent pleasant little shocks through her body, enough so that combined with her palm rubbing against her clit Shiratsuyu was already well on her way to her orgasm.
"You're really pretty, Shiratsuyu. Spunky-poi. I really like you" Yuudachi said, her eyes still closed, mouth hanging open. She wasn't quite panting, so Shiratsuyu figured she still had a ways to go.
"Thanks, Yuudachi. Your sex face is super cute. Can't wait to see your O-face."
"Won't be long-poi. How close are you?"
"Still got a long way, but I'm having fun! This is so lewd, just watching you is turning me on!" Shiratsuyu said. A shiver ran through her body and a coo of pleasure slipped out. "Geez, maybe I'm closer than I think~!"
"Hmmm" was all Yuudachi could muster. Her thrusting was becoming faster, more erratic. She wasn't producing any more precum, or if she was it was too mixed up in the lube to be seen. Yuudachi squeezed Shiratsuyu's breasts tighter, her fingertips digging into the plump orbs.
The sound of "hm-mm, hm-mm!" came from Yuudachi, and Shiratsuyu took it to mean Yuudachi was about to pop. Shiratsuyu stopped masturbating and put both hands on Yuudachi's tiny little tushy, which made Yuudachi's eyes flutter. The only sound she continued to make was that same sound. "Hm-mm! Hm-mm! Mmm!"
At last Yuudachi moaned into her closed mouth. A long, high-pitched cry of "hmmmmm~!" and her load vigorously spurted out and out onto Shiratsuyu's neck and face. Two of her spurts shot far enough to land in Shiratsuyu's hair and across her left eye, forcing her to close it. She squeezed Yuudachi's contracting butt and rubbed little circles on her hips with her thumbs as Yuudachi rode out her orgasm.
"FFFuwaahh! Mmpoi, that was amazing!" Yuudachi said, panting. She looked down at Shiratsuyu and her eyes widened. "Oh geez, your hair! I'm sorry! Nothing got in your eyes, right?!"
Shiratsuyu nodded. "Don't worr- Ah!" she said. When she opened her mouth some of Yuudachi's spunk fell in, the sharp taste unexpected. She licked her lips and swallowed. "Oh geez, it got in my mouth." She licked her lips again, testing the flavor once more. "Well, it's not bad I guess. Iku was right, though. Kinda slimy."
"I'm sorry! I'll.." Yuudachi started. She tried to move, but Shiratsuyu kept her hands firmly planted on Yuudachi's bottom. "I'll, like, clean you up, don't worry!"
Shiratsuyu smiled. She went back to rubbing her pussy, the strong odor of Yuudachi's cum filling her nose. "Just stay right there" Shiratsuyu whispered, and started stroking herself firmer and firmer. She used her two middle fingers to open her pussy again and rubbed circles into her vaginal opening, her index and pinky raking her outer lips. After a few minutes her orgasm rocked her; she arched her back, her legs straightened out, and the back of her head dug further and further into the couch. With a loud, girly scream she came, and it was over as soon as it had begun. She collapsed back down and released her hold on Yuudachi's butt, instead choosing to hold onto Yuudachi's hip as she came down.
"...That was so fun..." Shiratsuyu breathed, and Yuudachi nodded.
"Hm-mm! It was lots of fun! Glad you enjoyed yourself. Here-poi" Yuudachi said, and grabbed a few tissues off the end table. Shiratsuyu closed her eyes as Yuudachi wiped off her hair and face, making sure to get her neck too. When she was done Shiratsuyu still smelled of cum, but at least it was all gone. She let Yuudachi wipe off her boobs too, and when Yuudachi was done she flopped over onto the couch next to Shiratsuyu. "You were great, Shiratsuyu!"
"Ufufu~ Of course I was. I'm Number One~" Shiratsuyu said, and held her fingers over her open eye in a V-shape. Her other hand locked with one of Yuudachi's and the two of them snuggled closer together. "I hope we do this again."
"Don't worry, we will!" Yuudachi said, and Shiratsuyu looked down to see Yuudachi gently stroking her cock. "Don't worry, I don't need to go again just yet, but if you're, like, free later..." she said with a smile.
"If I'm not, I will be~" Shiratsuyu said, and that's all Yuudachi needed to hear. They shared a kiss and fell silent, content to just cuddle on the couch together for the time being.
"You really are Number One-poi" Yuudachi eventually said, and Shiratsuyu smiled.
"You know it~!"
