A moan

The reaction that he got wasn't what he would have expected though, as his hand came down on her ass he was prepared for her to scream in his ear, shout out at him that she was going to kill him, or even just knock him through a wall. What he got instead was a long drawn out and needy moan from the last of the Senju. He didn't let his surprise last long though as he decided to do it again, bringing his hand back and letting it ring out as he slapped it onto her ass once more.

"F-Fuck..." Tsunade let out another moan as his spank rang true and made her whole body shiver.

At this point Sasuke was left grinning. "Would you look at that, the great and powerful fifth hokage is a little slut for spanking. Or maybe its the Senju slut is just enjoying being handled by an Uchiha?" Each second that went by made Sasuke all the more cocky, something that was pretty obvious even himself, but with Tsunade moaning at his touch why wouldn't he?

"S-Shut up brat..." Tsunade stuttered a bit, a hint of red on her cheeks, though if that was because of the **** from earlier or a blush from being embarrassed nobody would know. The one thing that was known though was she wasn't denying it.

"You shouldn't talk to your betters like that you Senju slut." Sasuke emphasized it by giving her another spank on the ass, drawing out yet another lewd moan. "I think I should teach you just how much better we Uchiha are." With that Sasuke walked her into her home, intent on having a lot of fun with the busty blonde tonight.
