It's all up to Fuku's breasts and how she uses them

The biwa players saw an advantageous situation had developed. There was no need to bring out additional spirits for aid, nor to pull every trick out of their bag just yet. The samurai was effectively blind and immobilized while the sexy onmyo sorceress was putting on a good show for all of them. They rested their instruments and clapped along, cackling with decrepit, dry tongues as the shapely woman continued to act foolishly, driven by the mimicry of the mujina.

The mujina still had her hopping from foot to foot without a chance to rest, but finally, even it was tiring. It needed to do something a little less athletic. The creature was putting Fuku through a gauntlet unlike any mujina had ever subjected a playmate to before, but such was the nature of the ritual-- it had free reign to guide her as long as the ritual mandated. It wasn't ready to relinquish such a fun and skillful partner yet-- not when it still had so many fun ideas in mind for her!

The shikigami bent its knees, then hopped up out of the hot springs with another big splash, landing with its feet on the pebbles surrounding the spring. Fuku was **** to do that, struggling just a bit to stick the landing. Her bare feet had little traction on the wet stones, but she managed to keep her poise. "This mujina is resilient and... demanding," she huffed, now closer to William from the jump. "I fear I'll not be rid of it soon. But please, continue to close your eyes."

"Yes, Miss Fuku," William answered, finding this just as difficult a task as any trial the ritual could put him through. The woman was a feast for the eyes, the ideal Japanese woman with a body unlike any he'd seen here on the islands, now barely dressed and soaking wet... It was the kind of experience he didn't get a lot of ever since coming here and the kind of distraction that tested every samurai's resolve, though rarely in such an **** way.

The mujina continued to skip away from the spring, prompting her to do the same. It was growing closer to William... worryingly close for Fuka. When it giggled in its high-pitched voice, she saw his eyebrows twitch with recognition. "What is it going to do next? Sweep his legs from under him? Some other childish prank?" she thought to herself, frowning slightly as she observed its movements. William was a disciplined samurai. He could take whatever the mujina cooked up without losing his temper, but his anger wasn't really what she was worried about.

She followed the creature's movements with her hands as it raised each arm, then placed the palms of its hands on top of the shelf of its boobs-- the breasts that it had copied from her. It moved its hands, pushing down, and she was **** to imitate the movement. Its hands moved all the way from the top, squishing them as it reached the bottom, then grabbed up a heavy-hanging breast in each hand, pulling them upward. Her face reddened as she was **** to consider the size and weight of her own bosom, now pushing them up nearly to her chin. Then, it dropped each boob, creating an audible slap as they settled back down into place, jiggling with the impact.

Fuku heard William gulp as the sound registered in his ears.

"Please, continue to close your eyes," Fuku muttered, as the spirit repeated the action, but faster. She followed along, grabbing up each side of her breast, then dropping it back down into place with an audible plap. The speed increased more, until she was basically massaging her breasts with the action. She was thankful that the creature had at least stopped dancing around so that she could regain her breath, but this was inducing a different kind of breathlessness in her. She became aware of her nipples peaking a little bit, half from the exposure to the cool night air after exiting the bath, and half from the inherent arousal of fondling her own chest.

"What is happening?" William asked, as the sound became increasingly difficult to ignore.

"N-Nothing," she responded, closing her eyes in embarrassment at her own situation, unable to watch the grinning, spiritual double of herself play with its own tits. "Just stay the course." When she opened her eyes again, she realized the spirit's movements had changed. With a gasp of frustration, she tried to mimic its behavior, raising her hands above and behind her head to match the mujina's movements.

It had spread its legs a bit, bowing them into angles bent at the knees again. Now, it twisted its torso, swinging its huge boobs to one side of its body. Red-faced, she mimicked the action, slapping her tits to one side. It followed with the otherside, screwing its torso around so that its breasts swung in the widest arc possible. She was **** to do the same. The two of them were so close to William now that he could hear a swooshing sound in between the claps of the nearby biwa players and feel moisture hitting his chest, launched from some surface by a pendulous motion.

He felt himself getting painfully erect and hoped his onmyo teacher's attention would be elsewhere.

The twin Fukus continued to swing their breasts back and forth in time with the clapping, while bending their knees low and high. Fuku's eyes swapped rapidly between William's face, watching for some sign that he was peeking, and the grin of the mujina. She silently prayed that the torturous, embarrassing dance would end soon...

... But instead, it escalated, as the mujina stuck out its tongue and reached beneath its shirt. It yanked its bra down past its breasts, allowing them to spill out. The important parts were still covered... barely. Only on the topside and only by the practically transparent, clinging white fabric of the sailor suit top. The shape and color of her breasts could be made out easily like this to anyone paying attention.

With her face hot and her eyebrows twitching with indignation, Fuku pulled her bra down to match the other's. Then, the dance resumed, now with each swing threatening to further displace the shirt that was barely covering her otherwise naked tits. The samurai was unaware of the change, at least, and he seemed to finally be getting the hang of ignoring it. For that, she was thankful, at least.

It was a short-lived thanks, as the other mujina pushed forward a little closer. Now, instead of side to side, it began to move its back in a jerky, serpentine motion, forcing its tits to flop up against its chin and then settle down where they were. Worse yet, the way it had moved forward...

When she moved forward to match, she found that their breasts were now in contact. One pair slapped against the other, forming a revolving shelf in which each fought in a childish game to remain on top. The mujina seemed to be having the time of its life, as the wet mounds of breasts pushed and played against each other. Fuku realized that the shirts were becoming startlingly more and more displaced, likely only holding their place from the peaked nipples that were acting as anchors for them. Her eyes were now rooted on her own breasts and sweat rolled down her face, as she anticipated the tipping point where this dance would become, somehow, even more embarrassing for her.

They were so focused there that she failed to see William peeking one eye open, watching the show. Keeping his eyes closed during all of this had been too much to take after all... And, shameful as it was, he didn't regret taking a peek. This wasn't the kind of show you'd see at a saucy brothel-- it was something else entirely. A magical fantasy that could only occur in a secluded mountain like this with a woman like his teacher.

The biwa players felt they could watch this all night, but the time of the ritual was growing short. They needed to be certain not to waste a second...

Roll 2!
