He hates your second oldest brother, Sasuke to guts. While Itachi is mature and give you all privacy you need, Sasuke is always so damn protective of you, it pisses him off.

Like, Sasuke has his own girlfriend, Sakura. Why does he tries to meddle in his relationship with you?

So whenever Sasuke isn't home or around, (like today), Kiba makes the most use of it, spending time with you all the day and night, forgetting his training, well, since your annoying brother isn't always away.

He laps at you like a dog, running his tongue all over your body. He leaves your body sore with how wild he is, and he wants to do it to rail sasuke up too.
