"That's the spirit," Kayla says, reaching out with gentle hands. She strokes them over Emilia's skin, and moments later they're bathed in a gentle golden light. Emilia feels a deep sense of peace come over her, like reclining in front of the fire on a cold winter day, and the pain of her many wounds eases. Within moments, her flesh is whole, with nothing to show for the ordeal she's been through over the past day.
That done, the priestess rises and goes to her desk, from which she grabs a bottle and a glass. She pours a generous shot of the first into the second, the smell suggesting a strong brandy of some kind, and then caps it and puts it away. "Here," she says, offering the glass to Emilia. "Trust me, you're going to want it."
Whether or not the aasimar drinks, Kayla then leads her out of the office and back down the stairs, down to the same subterranean level where Emilia was previously fucked by thriae. She goes to a different door, though, and the room it reveals is different as well. A small, cozy room, it smells of beeswax and leather. A leather-covered massage table is the centerpiece of the room, with closed cupboards and leather armchairs spaced around it.
"Up you go," Kayla says, helping Emilia up onto the table. She then goes and rummages in one of the cupboards, returning moments later with a set of padded leather cuffs. She slips these onto Emilia's wrists and ankles and then attaches them to hooks on the table, leaving the aasimar spread-eagled on her back. A heavy leather collar goes on next, and is hooked to the table as well, so that she can't even move her head. Out of her peripheral vision she sees Kayla take a seat on one of the armchairs.
A few minutes later, she hears the door open, close, and lock. A pale Tien woman walks into view a few seconds later, wearing a long black robe. "This is the aasimar?" she asks, the question directed at Kayla.
"This is the one," Kayla affirms. "Remember the rules." There's a note of warning to this last sentence.
"Not to worry. I never overstep," the Tien woman says. Then she leans over and talks to Emilia directly. "Hello, pet," she says. "Are you excited?"
