An Injection

"With this Naruto" Tsunade said showing a needle with a purple liquid inside "really!" Naruto examined "and this will stop me gettting hard all time?" Naruto asked hopefully "well its just the first step in the process but yes brat it will, your still get hard just not all the time" Tsunade told him chuckling at his eagerness "there's more?" Naruto questioned "yes but we can do it all now so it's not an issue" "all right!, lets do it" Naruto whooped "all right, all right, calm down and lets begin" Tsuande grinning at Naruto

"Now take off your clothes and bend over the bed" Tsunade ordered him "huh? but why!" Naruto examimed a little nervously "it needs to be injected in the general area of the problem without anything getting in the way or it won't work now just do it brat or we can't get started" Tsunade said looking a little annoyed "okay, sorry Granny" Naruto said turning around and bending over presenting his butt to her "and Granny... thanks" Naruto said nervously "no problem brat now hold still" Tsunade replied with a little smirk as she grabbed Naruto's butt feeling herself stirr even more at finally getting to the ass thats been teasing her for far too long.

As Tsuande pushed the needle into Naruto's buttcheek what Tsuande smirked because what she didn't tell Naruto was that the injection didn't just help Naruto's 'problem' but it also increased the sensitivity and elasticity of his mouth, throat and anal muscles and while also stimulating the nervous system in those areas to increase the overall pleasure he will recieve there while dimming it in his genital area and also applying a sedative to make him more malleable for the next couple of hours or so. It also didn't matter where it was injected, Tsunade just wanted to grope Naruto.

Naruto moaned slightly form the needle exiting his flesh "you okay brat?" Tsunade queried "yeah just feel kinda weird all of a sudden" Naruto said "don't worry thats just the serum taking affact you'll be fine in a moment" Tsunade assured him "okay Granny" Naruto smiled at Tsunade, looking a little out of it "now stay where you are Naruto so we can do the second part of you 'cure'" Tsunade said "yeah, okay whatever you say Granny" Naruto mumbled eyes glazing over and sway a bit *chuckles* 'oh Naruto you making this too easy, and yes you will be doing whatever I say soon enough' Tsunade though licking her lips as she starred hungrily at Naruto's tight ass. Tsuande reached down and pulled out her twelve inch beast of a cock letting out a faint groan as it left her restrictive pants and thought 'I've been wanting that ass we've met brat and now I'm making it and you mine Naruto, before anyone else does" Tsunade smirked leering at Naruto's swaying ass.
