Yes

Fearing the worst, you glance at Kristin. The cloud of pure evil is hovering just above your sister...your sister! Gone is the succubus of moments ago, your little sister is lying nude on the floor, but it is your sister. The obscene red curves are gone, but you know the danger: that cloud mere inches above Kristin could bring that evil back to her.

Suddenly, with a gasp, Kristin's eyes snap open, only for her to shriek your name in horror at the evil just above her.

"It's okay Kristin, I'm here!" you shout through thankful sobs, rushing to her side. Gently grasping her arms, you slide her from underneath the evil smog.

"Thank you, sis'," Kristin mumbles, opening her eyes. Her blue eyes. Her beautiful blue eyes.

"I'm so glad to have you back!" you sob into the back of her head, kissing her gently.

"Oh my god! I'm so sorry, I--" Kristin begins to panic.

"Nonsense," you interrupt. "That wasn't you. Now let's find something to cover you up."

The two of you stand, careful to watch the seething cloud as you do so.

"You're right as usual. Anyway, let's check the storeroom," Kristin suggests. "We always kept extra clothes from the clothing drives, and I volunteered at the one last weekend, so there will definitely be something I can use!"

"Sounds good! Glad to have you back!" you smile.

The two of you begin walking to the storeroom, passing the holy water font and the pews.

"Race you there!" your childish sister is already sprinting, still nude, through the door.

"Silly kid--" suddenly you feel an overwhelming tingling sensation.

You begin to feel dizzy and stop walking, eyes screwed shut in concentration, but then you realize that you just have to breathe. You are stressed. Just breathe deeply and relax. Yes. Deep Breaths. Focus on breathing. Good girl.

You had no chance. Your thoughts were so focused on helping your little sister that you never noticed the tendrils of dark fog streaming into your mouth as you walked with her. The darkness found you to have more potential than Kristin; it chose you. And as you sink down to your knees, a wet spot forming in the front of your shorts, the last of the fog enters your body, and you hear the voice of Lilith again:

Cum for me and know power, know bliss, know...damnation!
