AUTHOR NOTE: For those wondering, Rhaegar married Elia and had Rhaenys and Aegon, then Jon. He isn't with Elia nor Lyanna, however, the three of them live together with the children (somehow)

Maths lessons are terrible, Jon thinks. He leans back lazily in his desk, fiddling the pages of his textbook, the teacher explaining the lesson.

"Please, review problems one through eight over the weekend", the teacher says as the bell rings, signaling the end of the school day. His brother is waiting for him, but before he goes, Sam approaches him.

"Jon, you were not even paying attention! If you continue like this, you will fail. I could tutor you a bit, if you have difficulties understanding the lessons", Sam says bluntly.

Jon bites his lower lip. He had to reject his offer, too embarrassed to admit the reason why he was bored in math classes.

He wasn't falling behind, in fact, he actually was ahead of his classmates. The reason was, well, his precious cousin, Arianne, started tutoring him -and Aegon- since his mother Lyanna saw that they both struggled a bit at the start of the term.

And today, he had another hour of reinforcement. Sam was his best friend, but his cousin came first in this.

"Good job!". Arianne grins at Jon, who has successfully solved all the equations without her help. "You are a really fast learner".

Jon can't help but smile back at her praise, his heart going crazy at the sight of the beautiful smile and brown eyes. Arianne is now 18, five full years older than him, and if she was beautiful back then when he was still a boy, now she had blossomed into a lovely young woman.

Having her wearing a tight t-shirt that displayed her cleavage so well didn't help his poor rampaging heart. Puberty was hitting Jon hard, and a very sexy Arianne along with his hormones brought out a filthy train of thoughts. Lately, the innocent crush on her had turned into something different, something that deeply embarrassed Jon.

In truth, she isn't my cousin, right?, Jon thought. So it is not wrong to like her... And he was right, they didn't share even a bit of blood. She was Aegon's cousin, not his, although they had been raised as if they were related.

"Urgggghhh! Fuck maths!". For his part, Aegon still had a difficult time with the lessons. It wasn't that he was stupid, he simply fared better in other subjects, such as history and literature.

"You, are as obtuse as always", Arianne laughed and leaned on Aegon's desk, going over the problems.

Jon gulped, the new stance making her large bottom stick out in the pair of jeans she wore. He didn't knew it, but Arianne was mentally smirking, knowing well that Jon was looking.
