"Tony Stark x Victor von Doom"

As soon as the doors opened again, Tony was racing through to his bedroom. He skidded into the doorframe in his enthusiasm, and began to strip.

"Seriously, no foreplay," he said as Victor stood up from the bed. "Just minimal prep. I wanna feel this the rest of the weekend."

"You'll feel it everywhere," Victor said, peeling off his clothing with much more finesse.

"Including my hip joints?" Tony said. "I'm bendier now, and I'm not gonna risk losing you a second time."

"Never again. I will always know how to find you."

Victor reached out and yanked Tony close. Their lips met, and never left each other while they finished undressing. Victor pressed Tony into the covers, still kissing him hungrily. Tony whined softly, cupping his soulmate's face. He tilted his head, and Victor kissed him deeper. One hand sneaked between Tony's legs and brushed over his hole.

"Where do you keep your supplies?" Victor murmured.

"Nightstand. There."

While Victor fetched the lube and a condom, Tony shoved the blankets out from under him. He did a few leg stretches, and yelped when a wet finger wriggled inside him.

"Little warning?" he said. Victor smirked.

"You were not paying attention, were you?" he asked.

"I need to be flexible," Tony said. He shivered at the coolness, even as Victor's fingers – two now, or three? – warmed to him. He closed his eyes with a smile. "That's it. Keep doin' that, Victor."

"Do you recall my promise to find something to keep you stretched for me all the time?"

"Yeah."

"You have been using something like that, haven't you?"

Tony flushed with embarrassment. "Box, bottom of my wardrobe."

"After I have come inside you—"

"But you got a condom out."

"I am giving you the option, Tony."

He stroked Victor's cheek. "That's sweet of you."

"Which would you prefer?"

"Bareback, but we'd better not. I wanna get tested first. Just to be on the safe side."

"Sensible," Victor said. "However, I would like to keep you ready for me."

"Yep," Tony said. "I see a lot more yoga happening in the future."

"May I watch?"

"I'll insist on it."

"Good." Victor smiled softly as Tony began to thrust down onto his fingers. "You look beautiful."

"I probably look sweaty and red."

"Beautiful."

"Why, because you're making me look that way?"

"Yes." Victor finally removed his fingers and pulled on protection. He slicked himself up, leaned over Tony, and began to inch his way in. Tony shivered.

"More," he said, clutching onto Victor's upper arms. "Please…"

"You're as impatient as you were last time," Victor remarked. He pushed Tony's legs wider, his eyes growing at the easy flexibility. Tony smirked, and tightened around him.

"Yeah, baby," he said. "The power of yoga."

"Remind me to thank Dr. Banner tomorrow. Or the next day. Whenever I let you out of this room."

"Good thing we've got all we need on this floor."

"All I need is you."

Tony snorted. "You old sap." Victor thrust in the rest of the way, and Tony threw his head back, arching up with a hiss. "Yes, please. More of that."

With a wicked grin, Victor began to move. He gripped Tony's hips, running his fingers over the joints and digging his fingers in to feel them. Tony moaned, and curled his legs around Victor's back. He raised his hips to meet his soulmate's thrusts, and tried to tug him down into a kiss.

"Not until we're bonding," Victor said, avoiding his mouth. "Consider it incentive."

"Now I know why you're a supervillain."

"Because I won't kiss you until our soulmarks meet? How petty I am."

Tony gritted his teeth as Victor brushed that sensitive spot inside. He tried to chase the feeling, but Victor was more interested in pulling one of Tony's legs from his back. It was his right leg, the one with the soulmark, and Tony groaned as Victor stopped moving, and held him down with one strong hand.

"I don't want you to hurt yourself," he said quietly. Tony shut up, appreciating the thoughtful gesture. He relaxed his leg, allowing the crook to rest on Victor's left arm as support while he raised his foot and hooked his ankle over Victor's shoulder. They were so close. With a little twist, Tony hoisted his knee from Victor's arm and let the entirety of his leg lie up his soulmate's body.

"There," he said. Victor waited for him to adjust before pressing forward again. The soulmarks were close to meeting, but not quite there.

Then Victor leaned down, and Tony whimpered at the pressure as his leg was folded back to his own torso. He lowered his other leg, and the angle caused Victor to sink deeper inside. When he was close enough to kiss, the soulmarks finally met. Light and warmth surged at the connection, and Tony realised that Victor was finally kissing him again. He opened himself up to everything, absolutely everything, and held his soulmate close as the tie was forged. He cried out when Victor began to torture that sweet spot again, and stars burst behind his eyes as everything became too much, way too much, and he reached his climax. He vaguely registered Victor swearing, and grinding into him. Tony nearly sobbed, did, in fact, start crying, and hated himself for getting so emotional. He was like this last time, too.

"It's alright," Victor murmured, and he kissed Tony all over the face. "You can cry. Let it out."

"I love you."

"Oh, Tony."

"I do, Victor."

He stroked Tony's side. The longer they stayed like this the first time, the stronger the bond would be. "I love you, too. Let me know when you get tired of this position."

"Someone I don't think there'll be an ache, even if we stayed like this for a year."

"That would be impractical."

"Asshole. You know what I mean."

"That doesn't mean I won't tease."

Tony studied his face, absently wiping away tears. "I could kill Stane all over again for doing this to us. Think what we could've achieved together."

"I do not see how he could have thought I would be a negative influence on you," Victor said, frowning.

"He didn't want me to have any support at all, except for him. I'm just pissed that I was taken in like that."

"You were not the only one," Victor murmured. "We were both too stubborn."

"I love you."

"You said that before."

"Is there a limit on how many times I can say it?" Tony clenched around Victor's soft length. "Because I'm thinking that anything like that would be illegal."

Victor laughed. He kissed Tony again, deepening it quickly. As the minutes passed, the bond became stronger, until Tony could feel it in every inch of his body. He could feel Victor, too, feel him inside Tony, around him, covering him. It was amazing. His emotions became clearer, until he could sense Victor's happiness, disbelief, hope, love. It was one thing to hear it; it was another thing entirely to feel the emotion. He was terrified of losing this, and initiated the next kiss. He could feel Victor growing hard inside him again, and rode him gently, desperate not to separate their soulmarks just yet.

"Careful," Victor whispered into Tony's mouth.

"Didn't I say I wanted to feel this tomorrow?"

"The rest of the weekend, you said."

"Please come inside me again."

"Nowhere else, sweetheart."

Tony grinned, joy overwhelming him. He was approaching orgasm again from that simple sentence.

"I like that," he said. "That's a good nickname."

"Merely a term of endearment."

"I like it anyway."

Elsewhere, the Avengers were discussing this development.

"Do you think he'll move to Latveria?" Steve said. Bruce shrugged.

"Can you see Doom working as an Avenger?" he asked.

"Not really."

"I'd say not at all. They could visit each other – they have the necessary money and resources – and it would be easier for Tony to live there than the other way around. But I think we're in for a long honeymoon period, so they probably won't be making plans for awhile."

"It sounds like they've kind of… earned it," Clint said, and he winced. "Can't believe I'm saying that, but things would've been different for them."

"Our history would be different," Natasha pointed out.

"Yeah, but they have a lot of time to make up for. Maybe we should send them back to Latveria tomorrow? The rest of us have to live here, you know."

"The soundproofing appears to be functional," JARVIS said.

"Even I can't hear it, which is a good thing," Steve said.

"It may be audible on your floor, Captain Rogers."

"…I'm sleeping down here tonight."

Always end with a note of comedy. Always. `Tis of the utmost importance!

Uh, yeah. Anyone got a request for the next bonding scene you want to see? I'm going through the ones where I've actually stated in-chapter where the soulmarks are located (so I don't have to think up places), maybe a femmeslash one? I've been thinking Jemma/Natasha. I've never written female/female smut before, not that I remember (and I think I'd remember), so you'd have to bear with me.

Please review!
