Who is Weiss trying to win over here? If it's Jaune, Ruby's boobs are about the same as Weiss's although maybe she's trying to compete with the memory of Pyrrha's boobs. If it's Blake, she's too busy swimming in cock to care about Yang's or anyone else's tits. If it's Ruby, why would Ruby want to bang her sister? Is she just trying to prove her sexual worth to Yang, who might be disappointed with someone smaller than her?
