How to become a Jonin

Since Sakura became a Chunin she wanted to become a Jonin but for that she needed to do some exams, but the Jonin exams were when a student felt he should do them, so when she figured she was ready she went to talk to the Hokage to ask her what was necessary for her to do the exams.
She talked to Tsunade, and she told her that the jonin responsible for the Jonin exams was Kurenai and if she wanted to do the exams, she would have to talk to Kurenai, and Sakura headed to meet Kurenai right away.
Kurenai was revising some exams when Sakura showed up, she was really busy, she gave Sakura an exam and she sat on a chair and tried solving it, but it was too hard, even for Sakura that was really advanced stuff.
While Kurenai was revising the tests she could see that in an hour Sakura hadn't answered a single question.
"What's the matter Sakura, you didn't study for the exam?" Kurenai asked.
"I did, but I don't know any of this these problems are so hard to solve." Sakura replied.
"You know that if you fail that exam you can never repeat it so you will be a chunin for the rest of your life right?" Kurenai asked.
"Yeah, I know that's why I'm so worried" Sakura replied.
"And you know that I will be the one revising those and if I want you can pass them, but for that you need to do something in return." Kurenai said.
"At this point I think I will do anything to pass these exams, so what can I do for you?" Sakura asked.
"If you worship my feet, and that includes having to kiss, lick them and suck on my toes, I'll let you pass." Kurenai answered.
"Really? But what grades will I get?" Sakura asked.
"Well, I guess that depends on how you worship them, the better you do it, the better your score will be." Kurenai answered.
"Ok, I'm willing to do it!" sakura replied
Kurenai took of her sandals and got her feet on the table, they were really sexy and soft, and the color of her nail polish matched the color of her eyes, Sakura had never worshiped feet before, so she just followed her instinct and her will to pass the exam.
Sakura started by licking Kurenai's left foot, she licked the tops of her foot, and the soles, and while she licked Kurenai moaned with pleasure.
Sakura was loving the taste of Kurenai's foot, and when her sole and the top of her foot were covered in saliva, she moved on to her toes.
Sakura wrapped her lips around Kurenai's big toe and started sucking on it, Kurenai was delighted, she was really enjoying to have a student worshiping her feet
Sakura sucked on Kurenai's toes one by one, she licked between them, and than she sucked on them all at the same time, Sakura than moved on to the other foot, and when she finished worshipping the both of them…
"I have to go now, it's getting late, what will be my score?" Sakura asked Kurenai hoping to get a really high grade.
"Well… 0 out of 100 per cent I'll give you 50 per cent, because you could have done a lot better, but you can do the test again some other time to get a higher grade." Kurenai said, and than Sakura left.
