He gives her a good fuck.

"Alright, now stand up and put your upper body on the desk for me, sticking your ass out," Naruto commanded Tsunade.

"Yes Master... Mooo," she cooed as she stood and positioned herself as instructed. He stepped forward and rubbed her ass as he fingered her with his other hand.

"Unh..." she moaned happily. "Oh yes Master... right there..."

He then lined his dick up and slowly pressed into her. "You're such a good cow girl slut," he praised her.

"Mooo..." was the only response she could articulate with the pleasure as he began to fuck her, and she wrapped her tail around his waist. Shizune of course didn't want to be left out, so sidled up behind him, pressing her bare body into his back and caressing him.

Naruto chuckled at the horny girls with him, in one case literally, and gripped Tsunade's waist as he began to pound her, making her moo loudly again. She tried pressing back against him as much as possible, and extended her arms to grab the opposite end of her desk.

Her pussy clamped down on him as he grunted, Shizune laying kisses on his neck as she embraced him, and he came again quickly, making her moo out in ecstasy as she orgasmed with him. Once he had filled her up, he pulled out, and she unwrapped her tail from him, just resting on the desk now.
