Violet Dress/White Micro Bikini

An interesting choice. Well you'll defenetly be able to tell the two apart now. But how to choose who looks like a lady and who looks like the tramp?

You decide its best to start things by asking the two their names. The one in front keeps her scowl on her face for a moment, unsure if she should answer. You cock your eyebrow at this. You were right before, this one is a gonna be trouble. Excellent!

Meanwhile the twin in the back row looks from the floor to you nervously. She is also unsure to answer but out of fear, rather than resistance. After a few more moments of awkward silence the twin in the back gave her name. "M-my name is Sera, m-m-my l-lord." Her voice was quite and cute.

You nod in approval, making sure not to smile. Gotta keep them guessing for now. You look expectedly at the other sister. She glances back toward her sister before answering. "Mera."

Somehow she managed to spit out her own name as if it was an insult. Looks like Mera is the confident one while Sera lacks any confidence and is far more submissive. Question is how do you use this info? Will you make Mara suffer for her attitude? Perhaps taking it out on her sister would better?
