Bargle comes to investigate.

The ornately carved oaken door opens and the bearded figure of Bargle suddenly looms in the frame, eying his slaves with calculating intent. His gaze falls on Lorn and she swallows. “My wards detected the use of magic...” he growls. He looks to the doppelgänger. “You. Kira. I’ve told you not to use you powers without my permission...” he turns to a desk loaded with sexual devices, selects a phallus inlaid with intricate runes and, with a mutter of a command word, the thing floats from his hand to wards Kira. “Now take the form I have instructed you to take...”

Her collar tightens about her neck and she winces. “Yes master,” she says with a resigned tone as she changes, breasts and ass swelling larger, waist narrowing and feature becoming angelic as she turns and presses her ass cheeks against the cage. The phallus pushes into her rosy lipped sex and she shudders in pleasure, dropping to her elbows and knees, ass high as the thing takes her in slow measured thrusts. She does seem to enjoy it, little noises of arousal filling the room.

Lorn pales, realising that could easily have been her fate, a strange tingling of arousal causing her nether lips to swell and moisten. She sees the amulet in Bargle’s hands and her heart beats faster. Does he know or suspect? What would he do if he knew? She tried to look feebleminded but Bargle looks at her.

“Feeling left out my pet. You can’t talk or understand words...” he motioned to his groin. “You can use that mouth and tongue for something useful.” An image flashed in her mind of her mouth about his cock. A picture paints a thousand words. The collar about her neck seemed to pulse and she felt the urge to obey. A strange submissive compulsion overcame her and she dropped to her knees and crawled over to him. Her mouth was watering as though she hungered something. It was man meat she wanted. Masters man meat. She was on all fours before him, petite breasts swaying from her narrow chest, her sex and nipples tingling with magically enforced arousal. She felt she should fight it... but then Bargle might suspect. Besides she wanted too please her master.

Her tiny hand reached purposefully into his robes and found the unmistakable bulge of his manhood. She gripped it and rubbed it, biting her lip coyly. Wet thrusts and moans from Kira and the tiefling **** filled her ears as she ran her hand up and down it’s length. It felt large and thick and wonderful and she wondered if he’d used magic to enlarge it. No. She was just smaller now.

Her master inhaled and exhaled deeply with contentment as she undid his robes and leant in to kiss his cock, mouth warm, breath excited, eyes rapt and focused on her prize. She engulfed his head and took him into her mouth.

“You’ve given up fighting I see. You’re a good little cocksucker my rebellious drow pet...”
