Sneak in through the back.

You count the buildings and find the backdoor that should lead into the massage parlour. You put a finger to your lips and nod to Eva, and then creep up to the door as quietly as you can manage. You turn the knob and it thankfully opens, allowing you to peer inside what seems to be a storage room filled with crates, towels, and more. With a movement of your hand, you beckon Eva to follow.

The two of you step inside. Eva snatches up one of the towels and wraps it around herself. It isn't very large, however. It covers the bottom half of her bust enough to conceal her excited tips, and it ends at her thighs. It does the job better than nothing.

"How's that?" you ask quietly.

"Better."

"Still a little drafty, huh?"

"Sh-Shut up. You're going to make me..."

Suddenly, the other door's knob turns. There isn't enough time to escape. It opens to reveal a woman with a sexy figure that reminds you of Linzeri's. She has long white hair, dark grey skin, horns, tiny wings, and is garbed in only what appears to be a black bikini with a spiky, fiendish flare, as well as heels. It looks as if she's just as surprised as you both are, despite her being the demon.

"What the hell?" she asks. "Why are you back here?! This is bad. You were supposed to come in through the front, and... Damn it. How did you figure us out?"

What?

"Oh, uh. It was obvious," you lie.

"He didn't tell us you'd be this clever. Well, I guess I'll have to deal with you both myself then. Your elf is already being taken care of."

Eva gasps. "Amara?"

The succubus smirks. "We discovered something very interesting about her. She has that mutation, where her mana is all bunched up, and it's in a very interesting place. Unfortunately for her, my companion's tongue has the ability to stimulate one's magical circuits. I'm surprised you can't hear her moans from here... but why is she naked?"

You look to Eva and then back to her.

I need a plan, and fast.
