Sex during bath time, what else? Though some confusion has to be worked through first.

"Miia, I brought Hubby!" Papi cheered as she rushed back in.

"I can see that Papi," Miia smiled at her new friend and playmate as Kimihito entered, shedding the last piece of his clothing, his underwear. Miia then let her tongue hang out again.

"So let's get cleaned up!" Papi started enthusiastically as she leapt back into the tub, splashing Miia and Kimihito.

"Hey, watch it!" Kimihito laughed slightly, before getting into the tub after them.

"So Darling, how do you want to do us?" Miia purred, moving her glistening wet body inna seductive manner.

"Well, I already fucked you once, so let's initiate Papi," Kimihito replied, making Miia pout slightly. "But don't worry... I'll have her eat you out while I do her."

"Oh, that works!" Miia brightened up, and Papi giggled at her.

"But wait," Papi said thoughtfully, bringing a wing up to her chin as she tilted her head, a cute look of contemplation on her face. "What's "eating out?" Papi doesn't want to eat Mia's insides..."

"No, eating a girl out means licking her pussy," Kimihito explained patiently.

"...but Miia doesn't have a cat..." Kimihito face faulted.

(Sorry if this humor is dragged on a bit, lol.)

Five minutes, and a lot of explaining later...

"Oh, Papi understands now!" Papi brightened up as Kimihito made a mental note to increase her understanding of sexual matters next time he had a chance.

"About time," Kimihito chuckled, and Papi immediately wrapped her wings around Miia's waist, and began licking her pussy, sticking her tongue into it. Miia cooed and gripped both sides of the tub as Papi began waving her ass tantalizingly.

"Come on, put it in," she smiled, taking her face off of Miia's wet cunt. He was tempted to take her ass, but decided to stick with her vagina this time around.

He knelt in the bath behind her, and after lining his cock up, entered her from behind. She moaned as he pressed into her with some effort. "Oh, this feels so good…" she cooed as he groped her ass cheeks, making them swell slightly, and began to fuck her slowly.

"Ditto," Kimihito joked, before giving her ass a spank, sending a massive jolt of pleasure through her.

"Ah!" she cried out. "Unh… do it again…" she begged, and he obliged, spanking her harder, watching her ass jiggle, and he resumed, going into her harder. "Yes, yes, fuck me!" she cried out. "Fuck me hard Hubby!"

Kimihito was all too happy to oblige as he gripped her waist, and was pounding her at this point, and then leaned forward, sliding his hands up her back, and around to once again grope her small tits. She squealed in delight as she milked his cock with her pussy all the while. She returned to licking Miia, who coiled her tail around her waist. Kimihito took the opportunity to grip the tip of her tail.

"Hnngh!?" Mia cried out, her eyes rolling up as he stroked that erogenous spot he had discovered before.

He continued to pump into Papi, until his cock throbbed, and he groaned out as his seed gushed out into her opening, and she screamed in orgasm, Miia's voice joining her. He pulled out, giving her ass yet another spank as he did. She looked back at him with sparkling eyes, and smiled massively.
