She takes the camera

After thinking for a few moments, Ruby came to the conclusion that the camera was the better option. While not being able to use her speed would slow her down, having a vibrator attached to her would likely do that even more. Not to mention, if she were to orgasm out there, she'd have to come to a full stop while she rode it out.

"Give me the camera," Ruby mumbled, reaching out to take it from Coco's hand.

"Ah, wonderful," Coco said, handing it to Ruby with a huge grin. "Truth be told, I was hoping you'd take this one. I want as many mementos of tonight as I can get."

Ruby rolled her eyes, but didn't say anything. With the camera in her hand, Coco extended the selfie stick to its full length of about 3 feet and turned on the camera. Its design was very similar to scrolls, with a rectangular glass screen that was somewhat see-thru and a dark circle in one of the corners. Only its use was far more limited.

Coco took the time to get it angled just right, capturing nearly all of Ruby's body in frame. At best, it was able to get from the top of Ruby's head to a few inches below her knees. Not the full picture, but it was enough for Coco to be satisfied.

"Alright," Coco said, smacking Ruby on the ass. "Get to it!"

In that moment, though, Ruby got an idea. It wouldn't completely save her form embarrassment, but it would delay it a bit. Ruby nodded at Coco and turned to the large window in the room, running towards it and flipping the switch, allowing it to swing open.

"Hey!" Coco shouted. "What are you-?"

Before she could finish, though, Ruby was already out the window. Being second years, their dorm was on the third floor of the building. A decent fall, but easily managed for a huntress in training. Coco hadn't specified that Ruby needed to begin the journey in the halls of the dorm room, just that she had to get to the lecture hall.

Ruby stood still for a moment, listening for any objections from Coco. After 10 seconds, she hadn't heard anything, and assumed Coco approved, at least begrudgingly.
