Winter!

Willow was the first to fall. Unfortunately she WAS the oldest, and her body didn't have the stamina to keep up with the other two.

Weiss was next to fall. Not for any particular reason or shortcoming - but more because well... this WAS Winter's job.

As an actual soldier, he was sure she did workouts on the regular. He wasn't sure how much sex she was having, or how often she was orgasming, granted, but her physical form was nothing to scoff at.

As the other two fell, Winter ceased and dropped to her knees, breathing heavily.

"Well done, private. How do you feel?"

Winter steeled herself and pushed to her feet. Impressive, as both Weiss and Willow were borderline unconscious on the floor at this point.

Her arm weakly shot up to her forehead.

"I feel... f-fine... sir..." she panted.
