A/N: This chapter is for my friend Elton, aka ADA-RafaelBarba on Tumblr. It contains an out there, love-it-or-hate-it kink, so if sounding isn't your cup of tea, turn back now. If you do like it, or are at least adventurous, go for it. Constructive reviews are always welcome.

He laid on the bed, face flushed as he looked up at Olivia.

For the third time that night, Olivia asked him the same question. "Do you trust me, Rafael?"

"Yes," he said, but it didn't satisfy her.

"Do you trust me?" she repeated, stroking his stomach.

He squirmed, not liking when the parts of him he felt self-conscious about were touched. Olivia always exploited this when she had him tied up, knowing he couldn't stop her.

"Do you trust me, Rafael?"

He closed his eyes and nodded. "I trust you, Olivia. Completely."

"How completely?" she asked, and it was then that Rafael realized she'd wanted that particular response, those words.

"Absolutely. With my life," he said, exhaling as the words sank in and he registered the truth behind them.

"Do you trust me to… to do things to you, without you knowing until I'm doing it?" she asked and held up a blindfold. "To keep you from seeing anything I do? Do you trust me not to hurt you?"

Swallowing hard, he nodded. "Yes, Liv. I know you'd hurt yourself before me." He nodded again, confirming his own words.

"And can I trust you to tell me if you need to stop?" she continued.

Another nod.

"Okay." Olivia leaned forward and slid the blindfold over him, then kissed his lips hard.

Rafael moaned, kissing her back. His erection had faltered a bit while they'd slowed down to affirm their trust for each other but he was getting hard again fast. "Liv," he breathed.

Pulling back, Olivia pulled open that all-too-familiar bottle of warming lube, rubbing it over Rafael's skin and making him moan as it heated up. She worked her way down his body, taking her time on his inner thighs and then coating the base of his cock with it. He whimpered in both pleasure and discomfort, squirming.

"Do you like that, Rafael?" she asked, stroking him with two fingers.

Moaning, he nodded.

"Use your words, Rafael," Olivia scolded him playfully, stroking harder.

He blushed. "Yes, I do, Liv."

"I'm going to do something different tonight," Olivia told him, moving off the bed. Rafael waited for her to return, squirming against the handcuffs.

When she came back, she kissed him until he was panting for breath. She reached down and stroked his cock.

"Liv," he moaned, tossing his head back. "Liv. Please." She laughed softly, teasing his slit with her thumb. He pushed his hips upwards, whimpering again. "Please. God Olivia, please."

Olivia let him go. Rafael closed his eyes behind the blindfold, breathing hard.

And then he jumped and gasped when suddenly, something was inserted inside his cock through the slit. He moaned and started to squirm.

"Stay still," Olivia instructed, stroking his face. "I don't want you to get hurt."

Rafael tried to stay still but couldn't, not when there was so much pressure inside him. "Olivia, what-what are you doing?" he managed to ask.

"It's called sounding," she began, but Rafael cut her off.

"I know what sounding is!" he said, panicking a bit and struggling against the handcuffs. "Why- what- just take it out! I don't want-"

"Rafael," Olivia said gently, still stroking his face. "If you want me to stop, I will. But… why don't you want it? I won't hurt you. You said you trust me."

"You didn't say you were going to ram metal inside my penis!" Rafael snapped.

"It won't hurt you, you know. It'll just cause some pressure and burning for a while. It won't… mess anything up. And this is surgical steel, sterilized, coated with surgical lube. You'll be fine." Olivia stroked Rafael's hair. "So what's wrong?"

Rafael closed his eyes. "I don't want anything inside me, not that way, Liv. It... feels wrong." He thought for a moment. "I'll try it. But if I don't like this, we're never doing it again."

"Of course." Olivia nodded. "But what feels wrong about it?"

Rafael let out a slow breath and struggled to voice his thoughts. "Just... my... my penis being... penetrated... it doesn't feel right." Olivia was still stroking his face. Any other time it might annoy him. Suddenly coming to a realization, Rafael asked, "but that's exactly why it appeals to you, isn't it? The idea that you're…" His face flushed. "Penetrating the part of me that usually does the penetrating?"

"Yes," Olivia admitted. "I like the idea a lot."

Rafael thought and finally said, "I'm not sure I can promise to like it as much as you do, or for the same reasons. I can't even promise to like it at all. But I understand why you do. And… I'll try it. I might end up liking it."

"I understand. I appreciate you trying this for me," she told him softly. "I promise not to hurt you."

"I know. That's the main reason I'm letting you do this," he said, smiling a little. He grasped the headboard, exhaling slowly. Part of him just wanted to get this over with.

He felt so very conflicted over this. He could understand the appeal, the taboo idea of that part of him being penetrated. It had a sort of appeal to him as well, and yet… It felt so wrong and frightening even aside from the issue of physical pain.

"Are you ready?" Olivia asked, gently stroking the underside of his cock.

Rafael moaned, nodding. "Yes. Go ahead, Liv."

Olivia slid the metal rod back inside slowly. Rafael squeezed his eyes shut, breathing quickly. It didn't hurt, not like he'd expect it to, but there was so much pressure that he could barely stand it. He bit his lip.

"Rafael? Are you okay?" Olivia asked, stopping and grabbing his shoulder.

"Yeah," Rafael assured her. "It's just uncomfortable."

"How?" Olivia pressed, stroking the underside of his cock again while easing the metal deeper.

Groaning, Rafael said, "It's… a lot of pressure… some burning and stretching…" He bit his lip, moaned again, and pushed forward, unable to stay still. "But it… it feels good too…" And it did, in a way he couldn't describe.

Olivia pushed the sound still deeper, until she found something inside him that made him shout in pleasure. He realized she'd managed to stimulate his prostate with the metal. "Liv," he whimpered. "Oh, Olivia. D-do that again, please."

She complied, pressing forward again. He gasped, feeling on the verge of an orgasm already. "Olivia… I- you're gonna make me come…" he moaned. The feelings against his prostate combined with the discomfort were overwhelming him.

"So you do like this after all?" Olivia teased.

"I-I will if you keep doing that," he whimpered.

Olivia paused, then rotated the metal a little, making him moan louder. "I think this one is too small for you," she mused. She pulled it out, leaving Rafael squirming again, and then inserted a new one. Rafael exhaled sharply as she worked it back in to where the other had been.

"How's that?" Olivia asked. "Don't just say a word. Describe it."

Rafael blushed again. "The stretching and pressure… they're more intense. But the burning is about the same. It's… it's good, still," he said.

Olivia nodded, easing the sound back down inside him, hitting that spot again and making Rafael shout. "Olivia!" She pushed it in again. He cried out, squeezing the headboard.

"I don't want you to come yet," Olivia informed him. So she stopped stimulating his prostate and pulled the metal back. She thrusted it slowly inside him, and Rafael's face blushed beet red. She was fucking his cock with a rod of metal and god he shouldn't be enjoying it this much. Just minutes earlier he had been terrified of the idea. But here he was, desperate for more of that sensation.

"How does it feel, Rafael?" Olivia asked, voice husky. She pulled the sound almost all of the way out and then back in, not nearly as rough as the normal motions for sex but still quite intense considering the body parts involved. "How does it feel, knowing your cock is getting fucked?" She slid the metal back in and then squeezed his dick, forcing the insides closer to the sound, and added, "Not physically."

Rafael gave a low groan. "I don't know, Liv," he said, tilting his hips. "I… it feels wrong. When you fucked me with the strap-on-" he groaned as the sensations got more intense again- "It still… wasn't like this. And I… feel vulnerable. But it's good. Different." He bit his lip.

"Good," Olivia told him. She pushed the metal all the way inside him and let it go. Rafael gasped, terrified, but then Olivia started pushing against his cock and somehow managed to work the sound back out. "I told you I wouldn't hurt you." she reminded him.

Shuddering, Rafael asked, "But… how…"

Olivia laughed, adjusting the blindfold on his face. "It's just how it works. Now, are you ready to come?" she asked, stroking him while she pushed the metal deep inside and started rubbing his prostate.

"Yes!" Rafael almost sobbed, tossing his head back. He moaned loudly, breathing hard. "Liv. Olivia. Please. I. I can't. Please. It's too, too much. Please." The strokes sped up, the sound went deeper, and Rafael was gone. He shouted, fluid spurting from inside him, forcing the sound out.

Breath ragged, he leaned against the pillow. Olivia kept playing with his cock until his orgasm had finished. Finally, she pulled off the blindfold. Cupping his face in her hands, she kissed him deeply.

"That was… different…" he managed between kisses.

"It was," Olivia agreed, kissing him again. "Did you like it?"

"I did," he admitted, a bit reluctant for reasons he wasn't sure of. "But I don't think I want to do it again too much. Every now and then, at most."

"Fair enough," Olivia said, nodding. She rubbed Rafael's shoulder. "And were you right to trust me?"

He smiled a little. It was important for Olivia to know that he trusted her so much. It reassured her that she could trust him, that it wasn't one-sided. "I was, Olivia. You didn't hurt me. You were careful."

Olivia hummed and kissed him again. After kissing her back, he suggested, "I might be able to kiss better if I was uncuffed."

Laughing, Olivia said, "Okay, I'll get on that." Rafael smiled, watching her do just that, feeling contentment well up inside him.
