Serenity's Punishment

So it occurred to me that when Serenity joined the team she wasn't payed in return for what she did to Shark and friends and so Serenity happily accepts her punishment as she chews on a nice ball gag while tightly strapped into a straitjacket. Eva is more than happy to give Serenity this much deserved spanking but for her it is more of a reward than punishment Serenity is such a naughty Neko.
