I guarantee you didn't expect this

"Hifuki, Celeste." The pair rise slowly, Celeste because she insists on keeping her refined lady persona even when buck naked, and Hifuki because she struggled to move fast with "her" new chest weights. It seems she lost a lot of weight in this world, then redistributed it in the most whorish way possible. "Hmm, seems truth is indeed stranger than fiction. I daresay this could make a rather racy work, yes Hifuki-chan?" The pair seemed connected in this world as well, but the partnership was definitely less abusive.

"Yes, hehehehe....indeed." She straightened her glasses and rebalanced her longer hair, reaching past her mid-back with dark curls. Her tits were as good as miniature mountains, almost obscuring her midsection if not for the perk all the girls seemed to have in their assets. While Celeste did have respectable breasts, what you'd notice first was how thick her thighs and hips were. With a bubble butt to match, it was apparent why she felt the need to wear those poofy, frilly dresses even in summer: Anything less and she'd look like she made her living in strip clubs instead of gambling dens. Drawn in by the air of sex and arousal that's permeated the room for a while now, Celeste pressed herself into Hifuki's mounds.

"Hifuki-chan, you are truly blessed." She sucks her nipple, leading Hifuki to squeal. "Your tits are the only thing I've seen who's splendor matches my rear. We have a gift, and have been given a noble path to use it."

Through her moans, Hifuki responds, "Ooh, yes...we must use our bodies for their intended purpose."

"My lord, please lay back." Makoto indulged them, taking up nearly the entire center circle. "Now," Celeste sits backwards facing near Makoto's crotch, readying herself. She snaps her fingers and Hifuki instinctively knows what to do, "Lose yourself in Hifuki's flesh while I see to my offsprings' conception." Hifuki presses her tits into Makoto's face, nearly suffocating him in pleasure pillows while he felt a pressure on his cock. Makoto takes charge, taking the writer's breasts into his hands to discover that sensitivity and size really do correlate. A touch makes Hifuki moan, a lick of the nipple causes an orgasm without fail. One nipple in your mouth and the other massaged by hand? It's hard to tell where one pleasured moan stops and another begins.

"Oh, yes! Imagine how they'll feel...when they're full!"

"Hmm, now that's a sight for the imagination." Celeste worked her pussy from behind, ensuring Makoto felt cushion for the pushin on both halves of his body. When he cums, his chest is soaked in lady juice from an enthusiastic Hifuki. Celeste slinks off, ass shaking as she limps to the refreshment area, and Hifuki takes her place.

"Wow, I never thought this would happen...could I use this for a--"

"Are we doing this or not?" Makoto knew Hifuki could get lost in her work, so he hurried her along.

"Oh, yes, my lord." Hifuki knelt suddenly, mammaries almost touching his cock before she positioned her pussy. "Oh, yes!" Like the others, she came immediately despite the prior pleasure. Through some miracle, her massive tits didn't hit her in the face, seeming to know the line between a sexy bounce and a painful one. As they fuck, lewd ideas flood Hifuki's head, her mind unable to focus on anything outside her head. Forget using this for one work, from this ritual alone Hifuki could create a whole serial of 'racy' fanworks. When he came, Hifuki slumped, muttering. "This can't be...I've been isekai'd..." Makoto lays her down and prepares for the next group.
