They accept

"Sure thing!" Naruto said with his trademark bright smile and cheeky grin, he didn't mind this and would show Sasuke just how much better he was. While it was definitely an odd way to show it the two of them were bitter rivals that always tried to one up the other through everything they did, this was no exception.

"Tch whatever. Let get this on with." Like always Sasuke was the opposite of his rival, trying to seem almost disinterested in all of this, however that couldn't be further from the truth. Sasuke might try to seem calm and collected but he definitely was as into this as his best friend/rival was.

Rolling her eyes at their predicable answers Naruko just smiled at the both of them. "Then lets do this! I am going to see which of you boys can handle a simple hand-job first." As she said this Naruko grabbed a hold of this thick rapidly hardening cocks and slowly started to jerk them off, her smooth wet hand gliding up and down the immense thick length of both their cocks.

Feeling this both boys let out groans of pleasure, loving the feeling of those soft hands of hers stroking their cocks, in the moment they forgot all about their little argument and this contest and just enjoyed the feeling of the blonde working them over. For over a minute Naruko did this, her hands going all the way to the tip of their now rock hard cocks, before gliding back down to the base.

"How is it going boys either of you think you are gonna bust a huge load?" Naruko asked with her own cheeky grin on her face as she looked to Sasuke. "Don't you just want to paint your best friends sister white with you seed?" She teased the black haired boy before looking at her brother. "Or maybe big brother wants to coat his naughty hot cum."

If she was trying to hide the fact that she was a total slut then she was doing a really poor job at it, after all only a depraved whore would talk like this to her brother and his best friend. Of course she could feel the twitching and throbbing of their cocks with them in her hands like this so listening to their bravado was more amusing than anything else.

"Not even close tch, unlike the loser over there I have some stamina." Sasuke insulted his friend, though they both knew that he didn't really mean anything by it, it was just trash talk in the middle of a competition. Though he said that he'd admit Naruko was way too good at this, and her dirty talk was making it all the harder to resist the urge to give in.

"Oi!" Naruto shouted with a tick mark comically forming on his brow. "Who you saying has no stamina! I am Naruto Uzumaki and stamina's my middle name! I can go for hours!" That was normally true but there was just something about his sister jerking him off and talking like that that was getting the older blonde off much faster than he wanted or expected.

Seeing the two of them like this Naruko decided that it was time to kick it up a notch, "Well if you boys are so confident I say we pick this up to the next level." Not wanting to be left behind by the other the boys both nodded their heads, not even knowing what that entailed.
