Marisa Kirisame cautiously fluttered down to the front doors of the Hakurei shrine from upon her broomstick. It was almost midnight in the land of Gensokyo, but thankfully it had been a spring day, so the air was still warm and sweet-smelling and the insignificant cries of a multitude of insects could be heard echoing throughout the small forest surrounding the shrine. Marisa was more than a little hesitant to go inside. She had forgotten something very important after paying her girlfriend Reimu a visit that same day, and it had taken nearly 12 hours before she had noticed it. Even worse, it was also something she was afraid to let Reimu see at all. It could easily end up destroying their five-year relationship.
'Well, I'm here already, so I suppose the only thing I can do is just go inside, and hope she hadn't even noticed the magazines...' she reasoned to herself.
Marisa slid the wooden door aside, and walked in. She didn't know whether to call out to Reimu or not. She looked up and down the old Japanese-styled corridors to her left and right. She sniffed; maybe Reimu wasn't even home right now. Marisa sighed, removed her shoes, and started to make her way in the direction of what served in the shrine as a 'living room' of sorts.
"Oh, Marisa, is that you?"
The blonde witch froze in her tracks. It was Reimu's voice. For some reason, though, it sounded slightly deeper than usual.
"Uh, hey, Reimu! Sorry I didn't say anything when I came in..." Marisa anxiously replied. Reimu chuckled.
"No, it's alright, I was just wondering if it was you. You're the only one who would drop by to see me this late, anyway," Reimu said this with a hint of sultriness in her voice. Marisa's cheeks flushed at the thought. She wasn't usually one to be taken off-guard like this and turned into a blushing belle (that was usually Reimu's job), but Marisa was still concerned about her secret getting out so she was an easy target now.
"Heh...yeah, you got me there!"
"In any case, I'm actually very glad you came. I have a surprise for you."
"A...a surprise?" Marisa hadn't been expecting this at all.
"That's right, so come into the bedroom. I also have your magazines too, since it appears that you've accidentally left them here,"
Nonetheless, Marisa heeded to her lover's requests, going straight for the bedroom instead. Reimu's bedroom was a place that the witch had become well-acquainted with in the early days of their relationship together. What Marisa found inside waiting for her, though, had been enough to completely turn her world upside down. Her heart started to beat just a little faster. It was as if she had suddenly stepped into some kind of dream situation without ever realizing it. A small trail of drool trickled down her chin.
The black-haired miko was sitting upright on the bed, casually glancing through Marisa's magazines, but that wasn't what had caught Marisa's attention. It was the fact that Reimu appeared to have spontaneously gained over 200 pounds within less than a single day that drew the other girl's eye. The now-fat young woman tossed the magazine off of her lap and onto the floor without a thought. Spread wide open, the pages revealed a number of photos, all of them consisting of large, but beautiful women in the nude. Marisa, however, was still too busy staring at her girlfriend to notice that her hidden fetish had been discovered.
Reimu smiled coyly. "I figured you would like what you see. You do, don't you?"
Marisa didn't reply. She simply threw herself on top of Reimu like a wild animal that had just found its latest catch.
The blonde reached out, hands greedily tugging at Reimu's soft, pudgy body. Reimu was very large, a girl whose weight was centered more around her midsection. She had a plump gut that drooped out in front of her by at least half a foot, and in her seated position it had folded itself into a pair of cute, squeeze-able rolls. It was slightly pale in coloration, and a number of thin, red vertical lines were scattered all across its surface. Marisa lightly ran her fingers over the doughy expanse, feeling out for Reimu's 'missing' belly-button between the equally thick rolls. Her belly jiggled and wobbled without abandon. It was all so incredibly meaty, but it still felt like she was hugging the world's largest pillowcase. Although the blonde had seen many bellies bigger than this it made a world of difference in the fact that this was a belly she could actually touch. Marisa moaned softly as her entire body became thoroughly wrapped within the heat of pleasure.
"Geez, Marisa, can't you - oof - be a little gentler with my body...? I only just became fat recently, you know. I'm still not used to it all yet."
"No. I don't want to."
Marisa clasped her lips over Reimu's. Reimu reached up and removed Marisa's pointed hat, allowing the girl's blonde locks to unfurl on top of them both. Slowly, Marisa's kisses began to trail away from Reimu's mouth and down her neck, and finally towards her lover's chest. Reimu, who had been flat-chested before, now possessed a pair of healthy, if not somewhat saggy, breasts. Marisa smiled; they were just so cute. She licked and sucked at the nipple of Reimu's right breast for a few moments. She could feel it harden against her wet tongue. Reimu shivered. As she pleasured Reimu's breasts with her mouth, Marisa used her hands to pinch every inch of Reimu's bulky, thick thighs that she could. They were so squishy, so blubbery. There was just so much of Reimu now, and Marisa was absolutely in love with all of it. It took most of her willpower to pull herself away from the miko long enough to ask a question that had been on her mind since this started.
"Hey...you know...how did you get so fat so fast in the first place?"
"Hmph," Reimu rolled her eyes, "Now you take the time to actually ask me about it."
"How could I have held back before? You were clearly tempting me then...weren't you?"
"...Yes, I was."
"So how did you do it?"
"I'll tell you."
Suddenly, Reimu grabbed hold of Marisa's waist and rolled her over, now switching their positions with the fatter girl on top. As far back as Marisa could remember, she had always been the one on top. But at this moment, with the heaviness of Reimu's fat-laden body lightly crushing her, Marisa didn't mind this change at all. She had a better sight at the chubby cheeks and double-chin that Reimu also possessed, as well. Reimu stretched her quivering arm behind her and tore something off of her back. It was a talisman. In only an instant, all of Reimu's fat seemed to melt away into nothingness, and she had reverted back to her original, slim self.
"R...Reimu..." Marisa couldn't help but feel slightly disappointed at this development. Reimu wasn't truly a fatty, after all. But then again, it could only be due to magic that someone would gain so much weight in so little time anyway.
"I was able to manipulate my magical energies to be able to temporarily alter my body, but it didn't last very long, so I use this talisman to help prolong my power and let me remain looking fat for a longer period of time. What do you think?"
"You sure come up with some interesting ways to use your magic, that's for sure,"
"And what about you? I was pretty surprised to see that that bag you left behind was filled with magazines of fat chicks. I didn't know you liked bigger women."
"It was always something of a secret of mine...I got the magazines and the bag from Rinnosuke, since they accidentally were mixed in with the shipment somehow, and he doesn't sell stuff like that, so he gave them to me since I was helping out. And, well, I kinda begged him not to throw them away."
"You always were kind of a pervert."
"By the way...I had made a talisman for you too, so we could enjoy it together."
Before Marisa could even react in time, Reimu had put back on her own talisman, and then placed a second one (which she seemingly pulled out of hammer-space, and slapped it onto Marisa's arm. The blonde's eyes bulged. She could feel the effects taking place almost instantaneously. Marisa's face puffed up, her arms and legs swelled, her stomach pooched outward, becoming soft and flabby. She was turning into a ball of buttery fat and fluff just like her Reimu. Marisa was shocked at how it felt, being coated in this layer of softness; it was amazing. She could feel herself be lifted off of the ground, but only by just an inch or two. Marisa groaned, biting her lower lip. Her ecstasy from turning into a fatty was abruptly cut short when she heard the sound of rips opening in her clothes.
"Oh, crap!" Marisa couldn't see the damage from where she was lying, but she could tell that both her pants and her shirt were now effectively ruined.
"Whoops, I forgot to tell you to take off your clothes first...sorry..." Reimu winced.
"Hmph. Well, I think you can probably make up for it with some sex-"
"Oh, I can do that!"
"...And then pay me money so I can buy new clothes."
"W-What? I'm just a shrine maiden, for crying out loud! I hardly make any money as it is!"
"It's the same for me! I work part-time at Rinnosuke's, and he doesn't get many costumers, and if he doesn't get paid, then I don't get paid either!"
"Let's just not worry about it right now anyway, alright? We have more...important...things to take care of,"
"Ah, right, right!" They began to rub their chubby bodies together, the resulting friction creating a sense of warmth between them. Reimu and Marisa kissed each other again. Their love had just gotten even better.
The suggestive noises that emitted from the shrine for the rest of the night and well into next morning was more than enough of a hint to tell any passerby that they would be best off staying far away.
