Actually, Kimihito has a fun idea for cleaning up.

"...oh, wait, I have a fun idea," he then grinned, making Miia's eyes widen.

"D-Darling, I might be enjoying having sex with you a lot now, I really am, but another round might be too much..." she chuckled nervously, before pausing. "Unless you intend to restore our stamina?'

"Tempting, but no," Kimihito said. "It's not going to be something involving sex, don't worry. Just get as much soap as you can on your boobs, and scrub us clean with them."

Miia blinked, before grinning. "Darling, you are so naughty..." she cooed, already moving to comply. She poured the body wash all over her boobs, and leaned over him, scrubbing his chest with her generous boobs.

"Hey, clean Papi too!" Papi pleaded as Miia kept going, and Miia grinned, shifting her focus to Papi. While it made the process take a little longer, and Miia had to put more soap on her boobs three times, it was immensely enjoyable. Soon, all three were clean, and they got out of the tub, Kimihito ordering them some pizza.

They chatted over dinner, before they finally headed to bed, Papi and Miia snuggled up against him, Miia wrapping her tail around the two, essentially gently tying them together.
