How open are the members of team RWBY about being daddy's girls?
(Sorry for taking so long, but now getting to answering these.)
In order from most ashamed to most willing to flaunt it?
Given all the effort Weiss went through to get away from Jacques, she is mortified how much she wound up enjoying serving as her father's cum slut and bed warmer. She tries telling herself that any pleasure she experienced was merely her focusing on getting to Beacon, and had nothing to do with taking her father's Schneenis.
Blake has slightly more positive, but still very mixed feelings about joining Ghira's bedchambers with Kali. On one hand, her father is unquestionably a better lover than Adam "Crimson McEdgehorn" "One Rage-Pump Chump" Taurus ever was, and the trysts she's enjoyed are more euphoric than all her filthiest smut novels could have ever made her imagine. On the other, she's pretty sure that most girls wouldn't consider their own fathers as potential rebounds, and she'd prefer not to give anti-faunus bigots and human supremacists more ammo to use for a race war - the propaganda writes itself, "Only filthy animals would dare engage in such filthy taboo debauchery!"
Ruby, being the social awkward butterfly she is, tended to bond the most with her dad and Uncle Qrow prior to her arrival at Beacon. Back at Signal, whenever her classmates brought up her male relatives' looks, she'd pretend to act grossed out that anyone would ever dare imagine them in the context of such FILTH - while also trying to keep from blushing at the memories of following in her mom's footsteps as the one who could help Qrow and Taiyang settle down. Of course, if she does find someone she thinks can keep a secret, she'll gladly talk about the fun times she's had with the "daddies" of Team STRQ.
And that brings us to Yang Xiao Long. While she might prefer girls most of the time, her daddy is the one man she loves the most of all. Its a bit of a delicate dance between the two Xiao Longs, as Tai doesn't want to force his daughter into anything she doesn't want - whereas Yang has made it clear multiple times over that she'd have no problem picking up the slack from her moms. She's got many reasons to become a Huntress, but amongst them are proving she's better than Raven Branwen. A better person, a better fighter, a better lover and a better wife and mother. And if that leads her to becoming her father's THIRD wife - and mother to her and Ruby's half-sibling - then she'll gladly take the honor.
Suffice to say, the last thing Team RWBY ever expected to have in common was being able to compare notes on their sex lives with their father's - Yang and Ruby enjoyed getting some outside perspective.
