Yep!

Once Shizune pulled off, looking satisfied, Tsunade pulled her other tit up to her mouth, just able to reach the nipple, and sucked out a small mouthful, before releasing it on her tits, slicking them up. She then stood so as to let her Master sit on the desk, which he did, and he undid his pants, letting his dick free.

"I never get tired of seeing your beautiful, hard cock Master," Tsunade cooed. "And especially not of this..." she knelt down and wrapped her tits on his length, the slick milk adding a nice warm feeling of lubrication.

"Heh, and I never get tired of seeing your slutty boobs," Naruto told Tsunade, making her coo as she began to moved her chest up and down on him. Shizune watched with a grin as she cupped one of her own tits and started to finger herself.

Tsunade licked at his tip, getting some of the slippery milk in her mouth. "Mooo," she sighed softly at the taste, flicking her tail about before she sucked at his tip.

He then grabbed her by the horns, pulling her down as far as her boobs would allow, making her eyes widen, before she moaned again, and pressed her tits together as he made her bob her head with her new handholds. He ground his hips into her mouth and breasts, before grunting as he released his sweet seed into her eager orifice. She pulled off once he released her, contentedly closing her eyes as she licked her lips.

"Mooo..." she moaned, before looking up at him sweetly.
