The broach left her hand with a small metallic click against the steel tray, and the sound was so final Tyler felt it in his teeth. Dr. Mack straightened, her pale blue eyes still on him, and for a moment she just stood there at the cart, her white coat immaculate, her severe bun catching the bulb's light. Then her hands moved to her waist, and she unfastened her slacks.

The whisper of the zipper was loud in the quiet basement. Tyler's eyes went wide around the bite block, his jaw already aching from the hours of being held open, and he watched her push the dark fabric down over her hips. She wasn't wearing anything underneath. The slacks pooled at her ankles, and she stepped out of them, one foot at a time, leaving them in a heap on the concrete floor. Her thighs were pale in the stark light, the thatch of hair between them dark and close-cropped, and Tyler's throat made a sound he couldn't control.

"You've been curious," Dr. Mack said, and it wasn't a question. She walked around the chair, her bare feet silent on the gritty concrete, and Tyler tracked her with his eyes because he couldn't move his head. The straps held him at the wrists, at the chest, at the ankles. The bite block wedged his mouth open so wide his jaw creaked. He was naked, caged, and she was circling him like something she'd already decided to eat.

Renata stepped in from the edge of the light, and Tyler hadn't heard her move. She was wearing her pastel scrubs, the mint smell of her clinging to the air, and her green eyes were bright in the dim. She carried the cage in one hand, the steel bars catching the bulb, and Tyler's stomach dropped when he saw it.

"I thought we'd give him a reward," Dr. Mack said, stopping at the head of the chair. She looked down at Tyler, her head tilted, and there was something almost tender in the way she studied him. "He's been so good. All those yeses."

Renata smiled, her dimples showing. "He has been good." She set the cage down on the cart beside the broach, and her fingers brushed the steel bars. "But good boys still need their rules."

Tyler's cock stirred against his thigh, half-hard from the cold and the fear and the strange, humming anticipation that had been building in him for days. He couldn't help it. The cage was a threat and a promise all at once, and Renata's fingers on it made his breath catch.

Dr. Mack swung her leg over the chair.

Tyler's whole body went rigid. She straddled him, her knees finding the steel on either side of his head, and the heat of her was sudden and overwhelming. Her bare cunt hovered inches from his face, the smell of her — musky, female, intimate — flooding his nose, and he made a sound against the bite block that might have been a protest or might have been something else entirely.

"Suck," Dr. Mack said.

She lowered herself, and her cunt pressed against his open mouth.

The first contact was wet and hot and so much more than Tyler had expected. Her flesh gave against his lips, slick and swollen, and his tongue was trapped beneath the bite block, pinned and useless. He couldn't close his jaw. He could only lie there, mouth wedged open, while she ground herself against him with a slow, grinding patience.

"Use your tongue," she said, her voice level, almost clinical. "You know how."

Tyler's tongue moved, clumsy and desperate, sliding against her. He found the seam of her, the soft fold of flesh, and pressed his tongue into it. She was slick, wet in a way that made his head spin, and the taste of her flooded his mouth — salt and musk and something darker, something that made his cock throb against the cold air.

Renata's hands moved to his groin.

Tyler felt her fingers on his half-hard cock, and he jerked against the straps. She was fitting the cage back over him, the steel bars cold against his skin, and the click of the lock was loud in the quiet basement. The sound of it — final, inevitable — made his eyes water.

"There," Renata murmured, her fingers tracing the bars. "All safe."

Dr. Mack rocked against his mouth, her thighs closing around his head, and Tyler's world narrowed to the wet heat of her. Her cunt was pressed so tight against his face he could barely breathe, and every time she ground down, his tongue was forced deeper into her. She was taking what she wanted, using his mouth like she'd used every other part of him, and there was nothing he could do but lie there and take it.

"That's it," she said, and her voice had lost its clinical edge. There was something raw in it now, something hungry. "Deeper."

Tyler's tongue found her clit — a small, hard nub at the top of her slit — and she shuddered above him. The reaction was involuntary, a ripple that ran through her thighs, and Tyler pressed harder, desperate to feel it again. He lapped at her, clumsy and eager, and she rewarded him with a low, guttural sound that made his cock strain against the cage.

Renata's fingers traced the bars, watching his eyes water. "He's learning," she said, and there was pride in her voice. "Look at him go."

Dr. Mack's hips moved faster, grinding against his mouth with a rhythm that was almost brutal. Her thighs were shaking now, trembling on either side of his head, and Tyler could taste her getting wetter, the slickness of her coating his tongue and chin. He sucked at her, drawing her clit into his mouth, and she cried out — a sharp, bitten-off sound that hung in the air.

"Yes," she breathed. "Like that."

Tyler's jaw ached. The bite block was a constant pressure, his mouth stretched so wide his cheeks burned, but he couldn't stop. Her cunt was on his face, her weight pressing down, and every instinct he had was screaming at him to please her, to make her come, to earn the release that was trapped behind the bars. He sucked and licked and pressed his tongue into her, and she rocked against him with a slow, grinding need.

"He's going to make you come," Renata said, and her hand closed around the cage, squeezing gently. Tyler's cock throbbed against the steel, desperate and denied, and he made a sound around Dr. Mack's cunt that was almost a whimper.

"He is," Dr. Mack said. Her hand found the back of Tyler's head, fingers threading through his sandy hair, and she held him there, pressed against her. "He's going to make me come, and then he's going to stay locked and aching, and he's going to understand what it means to be ours."

Tyler's tongue moved faster, desperate now, and she met him thrust for thrust. Her hips rolled against his face, her cunt slick and hot, and he could feel the tension building in her thighs, the way they clamped around his head. She was close. He could taste it, smell it, feel it in the way her breath came short and sharp above him.

"Don't stop," she said, and there was a command in her voice that cut through everything else. "Don't you dare stop."

Tyler didn't stop. He couldn't have stopped if he'd wanted to. His tongue was in her, on her, working her clit with a frantic, desperate rhythm, and she was grinding down on him like she wanted to swallow him whole. Her thighs were shaking, her breath coming in gasps, and Renata's hand was still on the cage, squeezing, watching his eyes water.

"Now," Dr. Mack gasped. "Now."

She came against his mouth.

Tyler felt it happen — the sudden clench of her, the flood of wet heat against his tongue, the way her whole body seized and shuddered above him. She cried out, a raw, broken sound that wasn't clinical at all, and her hips ground down on him one last time, holding him there, forcing him to take every drop.

He drank her. He had no choice. His mouth was open, the bite block holding him wide, and she was coming on his tongue, and he swallowed because he couldn't do anything else.

When she finally pulled back, her cunt sliding off his face, Tyler gasped for air. His chin was slick with her, his lips swollen, his jaw screaming, and the taste of her was still in his mouth. He looked up at her, his eyes wet, and she was looking down at him with something that might have been satisfaction, might have been hunger, might have been both.

Renata's hand squeezed the cage, and Tyler's cock throbbed against the bars — hard, aching, trapped. He hadn't come. He hadn't even been close, not with the steel locked around him, but his body didn't care. It wanted. It ached. It strained against the cage like a trapped animal, and Renata watched it happen with a smile that showed her dimples.

"Good boy," she said softly.

Dr. Mack swung her leg off the chair, her bare feet finding the concrete, and she stood there for a moment, her chest rising and falling. Her cunt was slick and red, glistening in the bulb's light, and Tyler could see the evidence of what he'd done on her thighs. She reached down and picked up her slacks, stepping into them without a word, and the whisper of the fabric was loud in the silence.

"That's the first lesson," she said, and her voice was level again, clinical, as if nothing had happened. "You learn to please us. You learn to earn your release. And when you understand that — truly understand it — we'll talk about what comes next."

She fastened her slacks, smoothed her white coat, and looked down at him. Her pale blue eyes were flat, patient, and Tyler felt the weight of that look settle over him like a blanket.

"Clean him up," she said to Renata. "And keep the cage on."

She turned and walked toward the stairs, her bare feet silent on the concrete, and Tyler watched her go. His jaw ached. His mouth tasted of her. His cock was hard and trapped and throbbing, and Renata's hand was on the cage, gentle, almost kind.

"You did so good," she murmured, and her green eyes were soft. "She's going to remember that."

Tyler's lips moved around the bite block, trying to shape a word, but nothing came out. He could feel the drool running down his chin, the cold air on his wet skin, and he nodded, a small, desperate movement that made Renata's smile widen.

"Good boy," she said again.

And the basement was quiet except for the hum of the bulb.
