Ooi wanted nothing more than to stuff her thick cock into Kitakami. Her pussy, her butt, her mouth, all three, it didn't matter. If someone came up to her and said she could fuck Kitakami, but then would die right after, she'd do it without hesitation.

Sadly, Kitakami seemed completely oblivious to Ooi's affection, and what's worse was Kitakami didn't have any marks: she wasn't a volunteer. Without marks or being in a relationship with her, Ooi was completely out of luck, and it was getting frustrating for her.

"Kitakami-saaan," Ooi whined to herself, alone in the dorm they shared. She paced back and forth by the window, the faint sounds of Summer nearly drowned out by Ooi's footsteps. Kitakami was out on a mission, not that it mattered anyway, since Ooi couldn't have sex with her. She didn't know how to get Kitakami to pay attention to her, except to just outright ask her to have sex with her, a move that was so crass and rude that Ooi wouldn't dare ever try it.

Ooi stopped pacing and let out a sigh. She wasn't really horny, but she had sex on the mind. Of course, she could just track down one of the volunteer girls and do it quick with her, but it wouldn't be the same. Kitakami was who she wanted, and she couldn't have her.

With another sigh and a huff of frustration Ooi walked over towards the door and was about to head to the bathroom when she saw something that caught her eye: on the floor, near the door, was a pair of Kitakami's panties. She knew it was a pair of Kitakami's because they were green, whereas Ooi wore only white. Ooi hesitated a moment before snatching them up and rushing out of the room, heading down the hall to the bathroom. In every bathroom on the base, to the left as one walked in, were two onaholes, built into the wall. Ooi hurried over to one and wasted no time slipping her now-throbbing cock out. What she was about to do was already making her heart pound, it was so exciting.

With lube applied Ooi held Kitakami's panties over the onahole, her thumbs in the leg holes and the crotch lined up with the entrance to the onahole, and slid her cock in. Kitakami's panties stretched to accommodate Ooi's six inches, and the extra layer from Kitakami's panties made the onahole even tighter, but it was the mental stimulation that was really getting Ooi going.

I can't believe I'm doing this, this is so lewd. Oh gosh, Kitakami, your pussy is so lovely Ooi thought, fantasizing about plunging her shaft into Kitakami. She was normally something of a jackrabbit, thrusting hard and fast even within a minute of starting, but the extra friction from the panties made it a bit harder for her. She huffed as she shoved her dick into the onahole again and again, over and over, loud shlicking sounds echoing lewdly in the bathroom along with her panting.

Kitakami, I love you! I can't wait to pump my load into you Ooi thought, picturing Kitakami naked in her mind. Thankfully for her Kitakami liked to wear skimpy swimsuits, so it wasn't hard to imagine her naked. She had such a lovely butt, such beautiful plump breasts, it drove Ooi crazy. There was more, too. Kitakami's thighs, her tummy, her pretty face and beautiful hair. Ooi had a passing thought that she'd love to stick the tip of her cock into Kitakami's belly button and thrusted harder, a shudder running through her.

"Oh gosh, Kitakami. Kitakami" Ooi breathed, her balls slapping the onahole hard. Ooi didn't particularly like onaholes, since the only way they could be used on the base was standing or squatting, but the intense release was always worth it. As fast as she liked to thrust Ooi usually lasted a fair while, but the extra stimulation from shoving her cock into the crotch of Kitakami's panties would make sure it wouldn't be long before she came.

Oh my gosh, I wish I could put my cock in Kitakami's butt. Her plump cheeks jiggling as my thighs hit them, my hands on her hips or pulling her braid. Kitakami you're so hot!

With her forehead against the wall Ooi moved a little closer to the wall and changed her thrusting style to pivoting her hips back and forth, her cock as deep into the onahole as it could go. She tightened her grip on Kitakami's panties, trying to be careful not to lose them in the onahole. There was a good chance her cock would stretch the panties out too much to be usable anymore, but Ooi was pretty sure Kitakami wouldn't notice one missing pair of panties.

"Kitakami," Ooi whispered to herself, now imagining Kitakami sucking her cock. "Gonna cum, Kitakami." Her thrusting had turned to pounding, a feverish, uneven pace as her lust-addled body rushed towards the edge. Her mind raced a mile a minute, a thousand different thoughts and fantasies about Kitakami running through it. Kitakami sucking her off, Kitakami riding her, titfucking Kitakami, pounding Kitakami's ass, it was all so much for Ooi. "Gonna cum.. Gonna cum..."

Ooi buried herself balls-deep in the onahole, threw her head back, and moaned long and low as her cock jerked and surged hard in the onahole, her rod twitching and pulsing intensely. She squirmed in place, trying to push forward even deeper into the onahole. Her orgasm ended and Ooi pulled out, some of her cum coming with her, and she dropped the panties to the floor. With a hammering heart and shaky breaths Ooi stood there by the onahole, basking in the afterglow.

Gosh that felt so good, I can only imagine how much better Kitakami's pussy would feel. Jeez, I can't believe I didn't pass out Ooi thought, her hands at her sides. She cleaned off and put her cock back into her panties, and took another moment to catch her breath. With a smile on her face Ooi left the bathroom, her legs quivering a bit, and headed back to her dorm, looking to drop onto the bed to relax.

She opened the door and was about to head for her bed when she saw Kitakami sitting by the window, reading. She looked up and, when she saw it was Ooi, stood up. "Hey, Ooi-chi! Where da heck have you been?" she asked, and rushed over to her. Ooi thought she was about to hug her, but instead Kitakami stopped short, her hands on her hips and a smile on her face.

"Hi Kitakami-san, I was just in the bathroom" Ooi said, trying not to sound too out of breath. Kitakami nodded and her smile widened. She set her book down on a dresser and finally gave Ooi that hug she was expecting, which Ooi gladly returned.

"I figured. I gotta go to the bathroom, too, so I'll back in a moment, kay?" Kitakami said, and stepped past Ooi. Ooi watched her leave and headed for her bed, collapsing on to it. Her heartrate had finally gotten back down to normal and her bed felt so nice, she couldn't help but feel a little drowsy. She wanted to stay up for Kitakami, but knew she wouldn't win the fight against her body. She shimmied back a bit until her feet were off the floor and shut her eyes, sleep approaching fast.

...

...

HOLY FUCK I LEFT KITAKAMI'S PANTIES IN THE BATHROOM!

Ooi shot up and scrambled to her feet, the sudden movement leaving her feeling a little woozy. She'd barely taken a step when Kitakami came back into the room, the cum-soaked panties in her hand. With the spunk plastered all over the crotch of the underwear there was no doubt who'd been using them and for what purpose, and Ooi felt her blood run cold.

Kill me, just kill me! Kill me, Kitakami-sama, it's all I deserve!

"Ooi-chi, do you have any laundry that needs doing? I've totally been puttin' it off and my whole hamper is frickin' full" Kitakami said as she stepped into the small washroom attached to their dorm. Ooi couldn't respond or even move, unable to comprehend that Kitakami didn't even question the state of the panties she'd found in the other bathroom. Kitakami soon came out of the washroom holding her hamper in front of her. "Ooi-chi?"

Ooi snapped out of her funk and stammered "U-Uh, um, n-no Kitakami-san, I don't have any laundry. Just take yours, it'll keep the load light" Ooi said, and Kitakami nodded.

"Kay, Ooi-chi, I'll be back in a few minutes" Kitakami said, and left the room, leaving Ooi completely dumbfounded. She... She wasn't mad? She didn't even mention it...

It was the weirdest thing, and Ooi couldn't explain. She could picture Kitakami walking into the bathroom, picking up the panties, and inspecting them. She'd easily be able to tell that they were hers, and she knew Ooi was a futa, and she knew that Ooi had just been in the bathroom. Ooi supposed that Kitakami couldn't know who had cummed on her panties, but all the evidence rightly pointed to Ooi, so then why didn't Kitakami confront her about it?

Ooi noticed that Kitakami had left the bathroom door closed and went to open it, stopping to look around inside when she did. The bathroom was pretty small, dominated mostly by a shower and a small toilet in the corner opposite the door. To the left of the door were two hampers, one for each of them. Ooi noticed something on her hamper and turned the light on, and when she saw what it was her heart skipped a beat.

A clean pair of Kitakami's panties, laid out perfectly flat on top of Ooi's hamper, with a condom on top of it. Ooi swallowed the lump in her throat and smiled, and reached out to pick both of them up.

I love you, Kitakami.
