See if Caroline needs more coffee

You slip out leaving Joe asleep. You head down to the lab to check on Caroline. You swing into the break room and grab her a candy bar and some of you special coffee.

You walk into the outer lab. Enough demonic magic is oozing out of your sisters, that you can feel it even in here. Several female lab techs seem to be trying to work despite their clear arousal.

You walk up to one of the techs whose white lab coat is embroidered with the name Kara.

"Hi."

Kara turns to look at you. She stares at your cleavage and bites her lower lip.

You give her a lusty grin. "Kara, have you seen Caroline? I brought her a coffee."

She points at the door to the inner lab, where your sisters are. Her eyes never leaving your cleavage.

"Can you let me in?"

Kara nods. She struts over to the door, puts her hand on the imprint and the door slides open. You step inside.

You smile at the scene before you. Within the glass containment cell, Megan and Amanda are gleefully fucking. Both have their faces buried in each other's snatches, and their tails in each other's asses. Megan looks up with an orgasmic expression and gives you a wink.

Clearly they have been fucking for quite some time as the glass has splatters of cum all over it.

Outside the containment cell Caroline and a lab tech, Judy you think her name is, stare at the prisoners. You notice Judy has slipped a hand inside her crotch and is discretely masturbating. Caroline's expression is distant. You walk up to her.

"How are you doing? I brought you more coffee."

Caroline still sits mesmerized by the debauchery in front of her. "They shouldn't still be going...they should have been exhausted hours ago."

You give a little giggle. "Why would they stop? They look so blissful."

"But...not normal."

You touch Caroline's shoulder and she shudders. You could just leave her with the coffee, or you could help her get some 'sleep'.
