It had been a busy couple of days, but Fubuki was finally free to take a day for herself. Naturally, of course, she was pretty horny, but at least she wasn't on a mission and unable to take care of it. She thought about visiting an onahole, but she'd enjoyed being with Jintsuu so much that she was really craving being with another girl. Jintsuu was out on a mission, though, so Fubuki was left looking for a volunteer.
So, Fubuki was in the dorm building next to hers, checking the dorms to see who was in. A few futagirls like Sendai and Yuudachi, a few non-volunteers like Kitakami and Amatsukaze, but everyone else seemed to be out either on sortie or expedition.
Fubuki sighed in disappointment as she checked room after room, finding them either empty or filled with futas and non-volunteers. She actually passed by a volunteer, Shimakaze, outside the dorm building, but Shimakaze blew by her and yelled something about going on a mission, leaving Fubuki in the dust. She was afraid that she really would have to use an onahole when she opened up one of the last dorms, peered inside, and found Shirayuki lying on her bed, reading. Shirayuki leaned up to see who had arrived, and when she saw it was Fubuki she got excited.
"Hi Fubuki-chan! It's so nice to see you!" Shirayuki said, and sat up. She smiled and Fubuki smiled back, and Fubuki walked over to her. "Got a day off? Do you want to hang out? I wasn't really planning on doing too much today, so if you want to go do something together we can."
Fubuki nodded. "Hi Shirayuki-chan! Yeah, I want to spend some time together. The last three days have been really busy, so it's nice to get some time off to spend with my friends" Fubuki said. She sat down on the bed next to Shirayuki.
"We're gonna have so much fun together, Fubuki-chan! Do you want to read some manga or go for a walk? It's such a nice day out!" Shirayuki said, and Fubuki rubbed the back of her neck.
"Well, we can later, but... I've got a problem. Can you help me with it?" Fubuki asked, pulling her skirt taut to show how hard she was. Shirayuki eyed her tent, smiled, and set down the book she was reading. She crossed her legs and put her hands on her knees, her beautiful brown eyes gleaming.
"You know what I have marks for, yeah? You sure you're ready?" Shirayuki asked, and Fubuki nodded. Fubuki watched as Shirayuki slid off the bed, turned around, and got onto her knees. She bent forward, her upper body on the bed and her knees on the floor, and flipped up the back of her skirt. "I'm here for you, OK?"
Fubuki licked her lips as she stared at Shirayuki's panty-clad butt, the white cotton perfectly stretched across her plump cheeks, a subtle dip along her crack. Shirayuki had marks for anal and vaginal, and Fubuki wondered just what it was like to stick it in another girl's butt.
"I'm... I'm gonna put it in your butt, is that OK?" Fubuki asked hesitantly, and Shirayuki hummed an acknowledgement.
"I've got a mark for it, so go ahead, if that's what you want. I just want to please you, Fubuki-chan."
Fubuki nodded and crouched down next to Shirayuki. She licked her lips again and tugged Shirayuki's panties down, her smooth butt making Fubuki's cock grow harder. Fubuki gently pulled the lube plug out of Shirayuki's bottom and set it aside. She removed her skirt and panties and squatted behind Shirayuki, her hands on Shirayuki's hips. She lined her twitching shaft up with Shirayuki's butthole and pushed, the lube making her slide in easily.
"Oh my gosh wooow, Shirayuki-chan, this feels so good" Fubuki said. She bottomed out in Shirayuki and leaned forward to press her chest to Shirayuki's back, wanting to be closer and more intimate with her. Shirayuki seemed to have adjusted to Fubuki being in her already, and so Fubuki began thrusting, the intense feeling making her hiss in pleasure. It was very much unlike vaginal; much tighter, much more resistance, more enticing mentally. She pivoted her hips to push back and forth, taking great delight in the feeling of her cock sinking deep into Shirayuki's tight tushy.
"Mmmm, it feels good for me too, Fubuki-chan. So intense~" Shirayuki said. She turned her head to the side and pressed her cheek into the sheets, her eyes closed. Fubuki put her chin on one of Shirayuki's shoulders and let out a content sigh. The way her balls kissed Shirayuki's pussy felt very pleasant as well; a more subtle feeling, almost overpowered by the sensations running up and down her dick and through her body.
Fubuki moved her hands from Shirayuki's hips and ran them up her body, eliciting a tickled shudder from Shirayuki. Her hands ran along Shirayuki's arms up to her hands, which Fubuki clasped, their fingers interlocked. "Wow, this is so amazing, Shirayuki-chan." Fubuki could feel her pleasure mounting, and thought back to what Jintsuu taught her. She slowed down, using her hips to pull almost completely out of Shirayuki before slowly plunging all the way back in.
"K-Keep going like that..." Shirayuki breathed, and Fubuki was all too happy to oblige her. She kissed Shirayuki on the neck, earning a giggle in return.
"F-Fubuki-chan that tick- Ohhh gosh... That tickles~" Shirayuki said, and Fubuki kissed her neck again. Fubuki picked up her pace again, slower this time, her breathing getting deeper as she went. Mutsuki said it was OK to cum as fast she wanted during anal or oral, but with how much Shirayuki was enjoying it Fubuki would feel bad if she just pumped and dumped.
"Fu... Fubuki-chan... I want to- to take my shirt off" Shirayuki said, and Fubuki stood upright, keeping up her pace. She watched with glee as Shirayuki's butt jiggled each time she thrusted in, but she slowed down to let Shirayuki focus on pulling her shirt off. She reached back to unclip her bra and Fubuki stopped her to do it for her. With her bra released Shirayuki was only clothed from her waist down, though with her skirt flipped and panties down not much was covered. With Shirayuki apparently comfortable again Fubuki bent back down to embrace her sister ship from behind.
"Maybe- Mmmnn... Maybe one day I could play with your...your boobs" Fubuki said, panting. She returned her hands to Shirayuki's, holding onto them to steel herself against the bliss. "Gonna cum soon, Shirayuki~"
Shirayuki moaned, again and again, incapable of coherent speech. Fubuki's pounding was becoming erratic, uneven. "I can't wait to cum in you, Shirayuki. You're so pretty, Shirayuki. Your butt's so tight~ Shirayuki~ Shira...yuki... Shi- Shira-! Y-Yuki! I'm...! G-Gonna... Gonna-!" Fubuki planted her face in Shirayuki's neck and moaned out in ecstasy as her cum started pumping out in rapid pulses. She writhed and grinded, her toes curled in her shoes. She again thought about how her own butt was up in the air, twitching and contracting in rhythm with her cock, and a fresh surge of cum spurted out. Shirayuki moaned as well, and her hands twisted futilely in Fubuki's grip.
Fubuki's orgasm ended and she relaxed, unclenching her hands and entwining her fingers with Shirayuki's again. Fubuki pulled out of Shirayuki's butt, and Shirayuki seemed to whine in frustration and panic a bit.
"Oh... N-No, Fubuki-chan, I'm... I'm so close! Please, just a little more! Put it back in, please!" Shirayuki begged, and Fubuki sank her cock back into Shirayuki's butt. Shirayuki yelped and buried her face into the sheets, and Fubuki started thrusting again. Shirayuki gripped the sheets and pulled, and she writhed harder and harder. It wasn't long before Fubuki's thrusting brought Shirayuki over the edge, the contractions of her orgasm tightening her butthole around Fubuki's cock. Fubuki grinded in place, already fairly close to cumming again. As Shirayuki's orgasm ended and her body unclenched Fubuki continued her pumping, the cool air on her ballsack, slick with Shirayuki's juices, a pleasant contrast to the warmth of Shirayuki's bottom. With a low groan Fubuki came again, her second load much smaller.
"Mmmmmohh my gosh, mmm~ Fubuki said, her orgasms over. She pulled out again, the tip of her cock kissing Shirayuki's butthole. She rubbed her shaft up and down Shirayuki's buttcrack a bit, a big smile on her face. All too quickly, however, her cock softened up again and she lied down on the bed next to Shirayuki, the two of them facing each other. Fubuki crawled up the bed to bring her legs and feet off the floor, and helped Shirayuki do the same. The two of them shared a kiss, and Shirayuki giggled.
"Satisfied, Fubuki-chan?" she asked, and Fubuki smiled.
"Yeah, Shirayuki~ It felt so great. I hope you enjoyed it, too."
"It was amazing, Fubuki! I'm so happy I finally got to make love with you" Shirayuki said, and Fubuki giggled herself. They snuggled up together in the afterglow. Shirayuki turned in Fubuki's grasp until her back was to Fubuki's chest, the two of them spooning. "Let's stay like this for a bit, OK, Fubuki-chan? Are you tired?"
Fubuki shook her head, even though Shirayuki couldn't see. "No, we can just snuggle if you want to" Fubuki said, and Shirayuki hummed earnestly in affirmation. The two of them got comfortable together and Fubuki wrapped her arms around Shirayuki, to which Shirayuki responded by taking Fubuki's hands into her owns. The two of them were left alone in the dorm, nary a sound in the room beyond their breathing and that of their own beating hearts, happy and content.
