Duh :P

"Okay, sure, we can mate," he grinned, and she gave a happy yip as her tail wagged a lot faster. He started to undo his pants as he gazed at her.

"Arf..." she cooed as she saw his dick come loose. She put her hands up on his torso so she could start licking at it. Once she got it nice and slick, she got down on all fours, panting again. "Master... You must be a real stud, mating with so many girls," she yipped.

"How did you know?" he blinked.

"Woof, you got a lot of women's scents on you," she panted out.

'...right, going to have to make sure no one finds my scent, and any of my other girl's scents on her odd with that Inuzuka smell,' Naruto thought. 'Hopefully Hana knows the names and faces of her whole clan, and their hound partners while we're at it.'

"Master?" she whined, seeing him lost in thought.

"Hmm, oh, nothing, just thinking I just dodged a bullet, don't worry about it," he chuckled. "Now go ahead and present your ass to me," he ordered.

"Arf, yes Master," she said excitedly, energetic and eager to please like a dog, which of course made sense. She turned around and waved her ass while her tail kept wagging.

He smirked, stroking his cock as he knelt behind her, and rubbed her ass. He lined his shaft up, and with a grin, pressed into her folds. "Aroo..." she moaned out as she was fully entered. Naruto pet her along her back and rump, and at the base of her tail while he started fucking her.

"Wow, you really are in heat," he teased her. "And quite hot too..."

She panted again, pumping back against him, letting loose a yip whenever he hit a sweet spot.
