Headcanon: Ruby was well aware both her libido and her fantasies weren't that common. After all when your tamest kink is being a size queen and routinely fantasized about having her organs re-arranged by just a massive bitch breaker cock for your first time instead of a sweet guy that took her on a nice date and made everything really romantic then she doubted her other fantasies would be anymore normal. Hell becoming a huntress was directly connected to her sexual desires.
She dreamed for years about going to Beacon and having all team orgies, whether they were boy or girl she didn't care. Heck it would be ecen better if yang were on her team, after all some sister on sister incest was hot as hell in her books. Oh she just couldn't wait. Her dad was great and one hell of stud that she wouldn't mind having a go at but unfortunatly he was still convinced she was just an innocent young girl that didn't know what sex was. Plus he had made his thoughts on incest very clear when they went over how some frontier villages conducted themselves. Not a whole lot of options, she could understand where they were coming from. But they apperently didn't share the same opinion so she discarded that fantasy unfortunatly.
Which was also one of the reasons she was so excited to be here, at Beacon Acadamy. Not only was she away from her seriously way to protective of a dad but she was going to find herself a hot stud, take him out grimm hunting and make him use her like a fucking cumdump on the dead and disolving bodies of the Grimm they killed, and she would of course have her baby Cresent Rose firmly in her hands preferably shooting at some grimm while she was used like a fleshlight and just wrecked by a stud.
Ruby was so engrosed in her day dreams and fantasies she didn't realise where she was walking and accidently knocked over a white haired girls luggage. If the girl was pretty hot and if she hadn't bitched her out immediatly Ruby was tempted to offer to repay her by eating her out. Unfortunatly the some of the dust leaked out of the bottle and she sneezed. Who knew so little dust could cause such a big explosion?
Laying in the crater of her own making she wondered if everyone at beacon would be like that white haired girl, hot but bitchy.
Jaune: Hey, you doing alright their?
Looking over she spotted the blonde that had thrown up on bullhead, but because of the new angle her eyes were drawn to the outline of his dick down his pant leg. Ruby Rose at that moment had found the person she wanted to go Grimm hunting with.
Ruby: Yeah thanks, I'm Ruby and you are?
The boy smiled back at her. And offer her a hand to help her up which she expected.
Jaune: Names Jaune, short sweet and ladies love it.
Ruby could help but giggle eyes dropping down to the outline of his pants.
She was so excited to be her at Beacon at long last.
