Chapter Text
For the first time in a long time, Reimu finally had some peace and quiet. She woke up to birds chirping as they flew out of their nests at dawn, then brewed herself some tea and drank it from the comfort of her kotatsu. No youkai crashed through her roof or kicked down her door, Yukari never came tits-first through a gap to drag her along with nonsense, and there was no party the night before, so she didn’t have to drag out the limp, hung-over bodies of any stragglers. She just enjoyed her tea and the morning ambience while she snacked on some rice cakes. It wasn’t exactly a meal, but Reimu was a skinny enough girl that she could last until lunch, and hopefully by then a visitor would be kind enough to drop off some food or money.
After breakfast, she immediately jumped into cleaning around the shrine. Despite her usual laziness, she felt invigorated by just how beautiful her morning was, so she grabbed her broom and stepped outside, ready for a relaxing day.
“ Heeeeeeey! ” Reimu recognized Marisa’s voice even though it was probably kilometers away, namely because of how it broke the silence she had been enjoying up until that moment. Reimu grumbled something under her breath and turned to face the black-and-white rocket homed in on her location. In typical Marisa fashion, she was careening through the air, leaving a trail of parted air behind her. Part of Reimu expected that she wasn’t going to slow down at all, but she did manage to skid to a halt in front of her, followed shortly by a thunderous clap.
“Morning, Marisa.” Reimu fought against her body to keep making eye contact, but failed when she saw Marisa trying to wiggle off of her broom. With hips wider than her shoulders, each motion was painfully exaggerated, only aided by the fact that her broom was now stubbornly wedged between her cheeks.
The sheer amount of jiggling flesh in front of her left her barely able to register her asking, “Hey, mind helping a girl out?” She turned with a hop, nearly taking Reimu out in the process as her dump truck swung right in front of her face, then came back down with a clap. She reached out a clammy hand to grab the broom and tugged it free. “Thanks a bunch.”
“N-no problem.” Once again, she found her eyes flicking down to the body-smothering pillows of Marisa’s thighs, with their smooth, pale skin, just begging to—.
“Are ya’ cleaning? Lemme help out.” Feigning ignorance to Reimu’s blatant perving, she sashayed across the shrine grounds, giving a glorious show to the stunned shrine maiden. Her skirt barely managed to cover her booty halfway, and when she moved at all it was rendered moot. One time, Yukari had described her ass as ‘about as big as two overinflated beach balls,’ and while Reimu had no frame of reference, she had a suspicion that the statement was spot-on. She couldn’t even see if she had panties on, probably due to them being wedged in her crack from her attempts at removing her broom from the same place. She was dangerously close to clapping her cheeks while she walked, but Reimu knew that if she ever said it out loud that Marisa would intentionally start doing it any time she was around, and she wasn’t quite sure she could handle that.
Even with the excellent ventilation provided by her outfit, she had begun to sweat and could feel the blood rushing from her head in favor of her lower head. She didn’t have a mirror but knew that her face was likely red as a tomato as it betrayed her attempts at appearing calm. She couldn’t stand the fact that Marisa wasn’t even trying and she was still a horny mess who had to consciously keep herself from drooling.
In the time it took Reimu to wrestle with her excessively intrusive thoughts, Marisa had returned with one of the shrine’s spare brooms and a smile. She never used her own broom for cleaning, explaining in the past that a witch’s broom was far too special to use for ordinary chores, but Reimu knew the real reason was that it gave her an excuse to bend over in front of her, usually accompanied by a slap of her rear to aggravate her further. Every action Marisa took was deliberately designed to rile her up and distract her; she was determined to ruin Reimu’s peace all for her own cheap thrills. Which was made all the more apparent when she decided to turn away to start sweeping, bending low so that her ass jiggled as much as possible. Reimu could feel the fabric of her skirt rubbing against her steadily awakening dick while she watched. She looked back at the broom in her own hand to remind herself that she was supposed to be cleaning and not watching that damn tease shake her ass right in front of her, and managed to force her body into action.
Things went well for a while. They both diligently made their way along the shrine grounds, Marisa even humming to herself as she did so. With spring transitioning into summer, there were still plenty of cherry petals to be found, but not so many that they ended up with big piles, so they were able to work quickly. Reimu was given time to slow her heart, and she was mostly soft. Against her better judgment, Reimu snuck glances every so often, (every five seconds or less) which also meant Marisa ended up far enough ahead that she decided to take a break while Reimu continued her duties. She wandered aimlessly for a moment before approaching her friend to strike up friendly conversation.
“I got new panties, wanna see ‘em?” she said as she leaned against the side of the shrine, jutting her hips out towards Reimu.
“I’m… trying to clean.” She kept her head pointed low to the ground and slightly away from the magician, doing everything in her power to keep her gaze ahead and not giving Marisa the gratification that she so desperately wanted.
“I’ll take that as a no. Y’sure?”
“Yes. Very.”
“Alright. Besides, I’ve rested my rump long enough, time to get back on the saddle.” Thank goodness, now she could keep working without Marisa trying to distract her—.
Marisa stepped right in front of Reimu and dropped her broom on the ground. She muttered some variation of ‘oops’ and stretched far down, baring her ass to the world, and, more importantly, Reimu. Her own broom clattered to the ground, prompting Marisa to turn around, wink, and flash a smile while sticking her tongue out. Her new panties turned out to be nothing at all, which meant that her puckering asshole was pointed right at Reimu as her dick rapidly grew even larger than it had moments ago.
“Uh, um, w-what… I…” Her face grew red both with embarrassment and indignation at her bottom-heavy friend for teasing her and interrupting her important duties, like she did so many times before.
“I told you about the new panties, didn’t I? That blue-haired kappa made them for me with her camo tech!” She clenched her cheeks and quickly let go to make them wobble. Finally, she picked up the broom and stood up straight, tugging her skirt back down to have some modicum of coverage. Reimu’s arms dropped stiffly to her side and her hands clenched into fists. She would get invisible panties just to mess with Reimu. She would come to the shrine and offer to help just so that she could bend over in front of Reimu like the slut she is. She would practically shove her gigantic, ground-shaking, impossibly fat ass in Reimu’s face just knowing that it would leave her a pent-up, desperate mess.
Her body quivered in place while she watched Marisa walk back and begin sweeping along the base of the shrine’s wall, returning to humming. She waddled forward like a toy soldier, each shift in her fabric sending shivers down her spine as it brushed against her cock, standing at attention and nearly poking out from under her skirt.
“ Grrah! ” She brought both hands down on her ass, hard. “Why do you have to come around here with so much damn ass? I can barely even think around this thing!” Marisa giggled, and Reimu responded by slapping it once more with enough force to leave a red mark. Marisa dropped the broom she was holding and slowly arched forward against the wall, placing her hands on it for support. Reimu was sucked in by the gravitational pull of the magician’s cheeks until eventually she was squeezing against her back with her skirt tent hovered above her ass and hot breath tickling Marisa’s ear.
“Aw, c’mon Reimu, it ain’t my fault; it runs in the family. You shoulda seen my mom, she was even bigger than me!” Images flashed in Reimu’s mind of Marisa, 20 years older, with an ass somehow bigger , spiking her blood pressure so much that her head swam. She couldn’t stop herself from bringing her lips to Marisa’s ear and nibbling on her lobe. Their body heat mixed together, especially at the hips, with Reimu’s raging erection tucking itself between those gargantuan globes of warmth, and it wasn’t long before she found her hips gyrating slowly.
Reimu removed her mouth from her ear and instead buried her face into Marisa’s tangled blonde locks, filling her nose with the fresh, earthy scent of home-made mushroom shampoo. “ Hnngh. Dammit, I don’t want to hear any excuses from you and your, huff, massive fucking ass.”
“I don’t hear my butt makin’ any excuses. If it could talk, I bet it would say that you ain’t trying hard enough.” The smirk on her face grew wider when Reimu puffed and forcibly clapped her cheeks together.
“Oh yeah?” Reimu found a smile of her own as she began properly pumping her hips with increasing force, her tip barely poking out from pillowy hills of Marisa’s ass at the peak of each thrust. Their hips were slick with sweat, producing wet slaps and squelches that grew louder each time they were slammed together.
“You’re so cute when you get competitive like this.” A jolt shot through Reimu’s body and made her heart skip a beat.
“S-stop talking!” she barked. “... and start moving, already.” She couldn’t stop her commands from sounding more like pouty whining. For once, Marisa obliged without any comment, and gently waved her hips, while Reimu continued fervently pumping hers. She huffed and puffed with each increasingly rough motion, meanwhile Marisa had a permanent, cheesy grin on her face and her moves were calm and practiced. Dammit, how many times had they done this before? The outcome was always the same, with Reimu humping her like a wild dog while she acted as if it was a normal encounter—which made sense, because it was. She was unbelievably frustrated just seconds ago, but that melted away, giving her a strange sense of clarity. As clear as she could be while getting an assjob from her best friend who also happened to have the softest, thickest, and tightest dump truck in Gensokyo.
“C’mon, I thought you were supposed to be trying. ” Oh, now she was asking for it. Reimu bit down on her shoulder, right where she had a sensitive patch of skin from a battle she lost a few months prior, and finally got a moan out of her. She continued her assault by taking hold of Marisa’s hips and tugging them against her thrusts, filling the air with wet plaps. The pace she set ended up making Marisa’s ass clap with each pump.
“I’m, huff, so… close.” Marisa’s breathing grew heavier and was peppered with gasps, though it was nothing compared to the intense grunts and panting that came from Reimu’s sweat-slick body. Pressure mounted from her core, growing alongside her increased speed. Each thrust grew harder, faster, louder. Her tongue lolled out of her mouth and a line of drool trailed down its tip. Their hips were a blur by the time she craned her neck back and blurted out, “ C-cum! Cumming! ”
Hot, white lines spewed up Marisa’s back, arching in the air before crashing down. Cum splattered between her shoulder-blades, all the way down to her shaking ass. Reimu continued at her break-neck speeds for several bursts, before finally beginning to wind down when Marisa’s lower back was nearly caked in her semen. She kept her grip on Marisa’s hips for support while recovering, and it seemed Marisa needed the wall for the same. They both took deep, long breaths, and Reimu graciously removed herself from Marisa’s ass to get a better look at her handiwork.
“It’s all up my back, ain’t it?” She slowly righted herself, trying to look over her shoulder. She lifted her skirt, giving Reimu another glimpse at her formerly-invisible underwear, now clearly showing its purple color wherever her cum didn’t coat.
“Yeah, it is. I think your new panties broke.”
“Dangit, she told me they were water-proof! This better get me a replacement, or at least a refund.”
“To be fair, she never specified that they were semen-proof.”
“Ha, that’s true. Once I get myself cleaned up, I’ll get back to helpin’ you with the shrine.” Even though she just came, Reimu couldn’t help but stare as she walked away. Once Marisa had stepped inside, she sighed and picked up her broom from the ground nearby.
She was just about to start sweeping when Marisa hollered, “Back to it!” It had only been a few seconds, how did she—.
Marisa bounded over to her, stark naked. Her breasts, while not particularly big, bounced with each step, and her ass clapped with each hop. Reimu felt something below her skirt beginning to stir, shortly followed by a twitch of her eye.
“Dammit.”
