The first thing Bucky did once he got his new slave home was turn him over to the servants to be bathed and groomed.

Stane had at least kept the slave clean. But Tony needed a bit of work to be presentable. And a long and luxurious bath with real hot water was certain to put Tony in a more agreeable mood when Bucky started his training.

Tony was returned to him in a tiny red thong, red silk collar, and a loosely tied bathrobe, hair still damp and the scent of Steve's sandalwood body wash all over him.

"Looking good," Bucky said. He tilted Tony's head from side to side so he could admire the line of his cheekbones and jaw now that his facial hair had been trimmed up neatly.

"Thank you, Master," Tony said quietly. "I haven't had a bath since…since…"

"Since before you were sold into slavery," Bucky guessed.

Tony nodded.

"So Stane lied about raising you from childhood then." Bucky wasn't surprised. Tony just didn't have the temperament of a lifelong slave.

"I was fifteen," Tony said. "My father was a struggling businessman and selling me seemed like the only way to keep the family business from going under."

Bucky patted Tony's shoulder. "I'm sure your family is grateful for your sacrifice. I'll take you around to check up on them sometime."

Tony blinked. "You would do that for me, Master?"

"Of course. I didn't buy you to keep you in a cage the rest of your life. But I'll have to make sure you're well-behaved before I can take you out of the house."

"I know how to behave," Tony said eagerly. "My master taught me-"

"Former master," Bucky said sternly.

"Former master, yes, sorry," Tony said quickly. "My former master taught me how to walk on a leash, how to stand for inspection, and how to respond if anyone speaks to me in public."

"I see," Bucky said. He was fairly certain Tony would have to unlearn most of Stane's teachings. But at least the man had taught him how to be quiet and submissive in public. "And what else did your former master teach you?"

Tony scratched the back of his neck. "He taught me how to assemble and disassemble the cages for market, do laundry, and make protein drinks."

"You've gotta be kidding me," Bucky growled. "You're a sex slave and he uses you for menial labor?" He was really going to have to teach Tony everything.

Tony shrugged. "I was too young for most people's tastes when my master, er, former master purchased me. So I had to make myself useful in other ways."

"Please tell me you're not a virgin."

"No, Master," Tony said quickly. "I've had sex."

Bucky breathed out a sigh of relief. "Any experience with men?"

"Not much," Tony admitted. "Stane mostly hired me out to older women who wanted to fantasize I was their hot pool boy for the day."

"Such a waste. It means I'll have to spend more time on your training." Bucky reached into the large box of sex toys he and Steve kept in their closet and pulled out the smallest dildo they owned. "We should get started right away."

When he turned back, Tony had gone pale and stiff.

Bucky raised an eyebrow. "Bad experience?"

Tony nodded. "Former Master tried one on me once." He grimaced. "I was bleeding and in a lot of pain. Former Master was angry about the cost of medical treatment and even angrier when the doctor told him I needed to abstain from sex for a few days."

"And he never tried again?"

Tony shook his head. "He said my ass just wasn't meant for penetration."

"Ridiculous," Bucky muttered. Tony had a great ass. It was so pert and round, perfect for squeezing, perfect for fucking. "I'll prove him wrong right now. Strip and get on the bed."

Tony's eyes went wide. "Right now?"

"No time like the present. Go on, I gave you an order."

Tony let the bathrobe fall to the floor and began awkwardly sliding his underwear down his thighs.

Bucky added the art of undressing to the mental list of things he needed to teach Tony. It was going to be a long list, he was afraid.

Tony settled on the edge of the bed, hands clasped in his lap. "Okay, I did it."

"Hands and knees."

Tony quickly got into position, trembling a little as Bucky adjusted his stance.

"I don't want to hurt you," Bucky said. "And I'm not going to hurt you if you stay nice and relaxed. So how this all goes depends on you."

Tony sucked in a deep breath. "Okay," he said. "Okay, I'm ready."

"Good." Bucky slicked up one hand with lube from the bedside table. "I'm going real easy on you to start with. Don't want to damage the merchandise."

Tony's body was radiating tension and Bucky had to sternly remind him to relax or it was going to hurt several times. But eventually Tony's muscles relaxed enough for Bucky to insert a finger into his anus and crook it just right.

Tony howled and his back bowed. "Oh fuck," he murmured, a dazed expression on his face. "What was that?"

"That's your prostate," Bucky said cheerfully. He stroked the little bundle of nerves. "Feels good, doesn't it?"

Tony nodded eagerly and arched back into Bucky's touch.

"See? Stane doesn't know a damn thing about slave training. Your sweet little ass is just begging for penetration."

Bucky inserted a second finger, pleased at how easily Tony's body opened up for him now. He scissored his fingers, making sure Tony was good and stretched before pulling them out.

Tony whimpered at the loss.

"Patience, pet." Bucky coated the dildo with a generous amount of lube. "Stay nice and relaxed for me."

He eased the toy in slowly inch by inch, past Tony's tight ring of muscles, until it bottomed out.

"That's it," Bucky said encouragingly. "You're doing so well for me."

He worked the toy in and out, smiling as Tony gasped and moaned. Steve was going to love him. He always had a thing for vocal slaves. The louder the better.

Tony's moans grew into keening cries as Bucky sped up, plunging the toy faster and faster into the slave's willing hole.

All too soon, Tony's body locked up and he collapsed face-first onto the bed with a breathy whimper. Bucky really would have loved to play with him a little longer, but Tony was still a teenager and short stamina was just a fact of life. But the fact that he could come entirely from anal stimulation more than made up for how quickly he finished.

Tony's eyes fluttered open and he forced himself back to his hands and knees. "Was that satisfactory for you, Master?"

"More than satisfactory. You've taken remarkably well to anal play. There's so much more I want to try with you. Butt plugs, vibrators, anal beads. Steve and I have an extensive collection." Bucky considered the large box of sex toys. "Some of these will probably hurt at first." He pulled out a fairly thick 8-inch dildo. "This one's a little big for a beginner."

Tony shuddered. "That's about the size of the thing my former master used."

Of course it was. Fucking Stane.

"We'll work up to that one," Bucky assured him. "With a little practice, you'll be taking even bigger than that." He'd have to. Steve was a little over ten inches.

"Are they all going to feel that good?"

"That's up to you," Bucky said. "But we'll find out soon enough."
