She produces a dildo and fucks Sakura's ass.

"Now then, one more bit of fun before I take my leave and go on business," Ria mused, reaching into her chest, her hand just phasing into it, making Naruto blink and stare.

"Umm..." he asked, and Ria looked at him curiously, seeming to rummage around.

"What? Do you see any pockets on me? We Erokami store our valuables, including our Notes within our bodies, we can control our intangibility to that extent, and are immortal, so keeping objects inside us is extremely convenient."

Naruto couldn't argue with that, and Ria said, "Oh, here it is..." She then pulled out a dildo with two ends, and proceeded to strap it on herself, inserting the inner end into her own pussy. She then beckoned Sakura to assume the Kitty Style position, which Sakura eagerly did without needing telling twice.

She waved her butt at Ria to entice her as the Erokami floated behind her, and pressed the dildo into her pussy. "Nyah..." Sakura cooed as Ria started to fuck her, before pulling the dildo out. "Nyah?" Sakura asked, looking back as Ria gave her more or less unspoken question an answer by moving herself up a little and pushing the now slick dildo into Sakura's ass. "Nyah!" she yelped, clenching her fists as her butt felt the pleasure of penetration, and she turned to face forward again, moaning all the while as her tail kept swaying.

Ria moaned as she began to fuck Sakura's ass, the part of the dildo in her shifting with every thrust, before she looked up at Naruto, who was still pleasuring himself slowly. With a chuckle, she moaned, "You know, I'm feeling generous right now, she has an end I'm not using..."

Taking the hint, Naruto walked over and knelt down, his dick throbbing in anticipation. Given permission from her Mistress to give her beloved Master some attention during her Mistress's turn, Sakura meowed again and began to happily lick at Naruto's rod.

Ria sped up as Sakura took Naruto's manhood into her mouth, and bobbed her head. Naruto of course increased her pleasure further by petting her cat ears, making her purr around his cock.

Ria pounded into Sakura, grabbing her tail as she did so, and Sakura kept on mewling and purring as she fondled Naruto's balls, wanting nothing more than her sexual owners to take pleasure in her body.

Then the three came, Ria and Sakura shrieking as their pussies spasmed and Naruto came in Sakura's mouth, which she gulped down greedily. Both Naruto and Ria pulled away, and Sakura sat up, smiling warmly at them both.
