Ianto developed a sense for detecting trouble early in his life, and had honed it working for Torchwood. He knew when he was in trouble, and today seemed to qualify. Stuck in an alternate universe with a Jack Harkness that wasn't His Jack, but was still Jack, well, it had the words 'disaster' and 'train wreck' written all over it. He moaned softly as New Jack kissed along his neck.

The problem of being in an alternate universe was that a) he wasn't in his own, and b) His Jack would be frantic trying to find him. He knew His Jack felt strongly towards him, had seen the wistful looks, had heard the almost-spoken confessions late at night when they were falling asleep in either of their beds. He knew His Jack would do everything to get him back, and he was going to do whatever he could to increase the likelihood of that happening. He couldn't leave Jack alone. He'd lost too much and too many people already.

Ianto sighed, wondering if he'd be able to convince his heart that he wasn't cheating on Jack, because, well, this was Jack, too. Despite what he'd said earlier to New Jack, he hadn't slept with anyone but His Jack since the moment His Jack asked him out so tentatively in that office building after coming back from his travels with the Doctor. There were no more threeway offers from His Jack, and Ianto suspected that His Jack hadn't been with anyone else, either, though he had no proof either way and wasn't about to actually ask. That would expose too many of his dreams and wishes, too many of his hopes that Jack would be his and his alone.

But he also knew that Jack wasn't designed for fidelity, so how could His Jack begrudge him a night with New Jack, especially if it was a ruse to get back to His Jack? And it's not like he wasn't being forthright with New Jack. He told him that he'd seduced His Jack for his own purposes. He told him he wanted to go back to his universe and His Jack. So maybe it was ok to do this?

It was still Jack he was grinding his hips (and erection) against.

He took a firm hold of New Jack's head and kissed him heatedly on the mouth, while at the same time he backed them up so that New Jack's calves bumped against the concrete 'bed.' He pushed New Jack down until he was sitting, then got on his knees before him.

"Shirts off," he barked at New Jack, even as he undid New Jack's belt, unzipped his fly. New Jack rushed to do what he said, lowering his braces and peeling his way out of his clothes. Ianto undid New Jack's boots and pulled them off, then the socks and trousers and boxers, leaving New Jack lying back on the concrete, his entire body on display for Ianto. The rush of lust that filled Ianto's veins as he looked down at his lover – no, the man with the same body that wasn't his lover – surprised him. New Jack didn't know him, didn't know their relationship, and wasn't that part of why he was so attracted to His Jack? Their shared experiences?

His cock, trapped in New Jack's too big for him trousers, didn't seem to care and stood at attention.

New Jack looked at him with wanton eyes, running a hand down his chest, pausing to tweak a nipple, then over his abdomen until he reached his erection. Ianto watched for a moment, distracted by the sight of Jack's cock bobbing in his fist. He shook himself, bent to kiss New Jack with a bit of gentleness. New Jack responded eagerly, pulling Ianto down on top of him so they could rut against each other.

"You want a blow job first?" Ianto asked, deepening his accent, hoping New Jack would accept his offer. New Jack nodded enthusiastically, sitting up and spreading his legs wide for Ianto to kneel in between them.

Ianto started slowly, one hand holding New Jack's cock at the base, holding him steady, while the other stroked his inner thigh. He began licking and sucking. New Jack started cursing, a good sign. He'd eventually stop cursing and start with endearments, but Ianto privately doubted it would get that far. Ianto picked up the intensity of his ministrations, leaving off stroking New Jack's thigh to free his own cock. New Jack looked down, briefly, was reassured that Ianto was just taking care of himself, and abandoned himself to Ianto's mouth and hand, leaning back and groaning, his eyes closed so he could concentrate more fully on the sensations. Ianto smiled to himself and reached for New Jack's trousers, which were puddled on the floor.

One habit that took him almost six months to break His Jack of was losing his security swipecards. Not outside the base, mind you, but inside the Hub. It was, in part, how Ianto was able to get Lisa into the Hub so secretly. He'd had one of Jack's swipecards. His Jack would just forget and leave them around, in the greenhouse, in the armory, on the coffee or conference table, under Tosh's station, in the firing range, lost on his desk. Ianto found one in the morgue, once, after he started a daily routine of looking for them. His Jack had carried more than one at a time, just in case, and sometimes would start the day with as many as five and be asking Ianto for one by lunchtime, if he took to wandering the Hub, bored.

When he and His Jack got back together after the incident with Suzie, the second incident, Ianto decided that he wouldn't keep enabling Jack about the cards. (And other things, but the cards were the security risk, so he started there.) Every time he found one in a random place, he would calmly walk into Jack's office, shut the door and wait for his lover's attention. Once he had it, he dropped the card into the middle of the desk and informed Jack that they were not having sex for 24 hours. Jack always tried to protest, to seduce him, to get out of it, but Ianto managed to hold on, and Jack learned not to lose his swipecards.

It was interesting, Ianto noted, still rooting in New Jack's pants, that His Jack never considered going on the pull on those nights, and always spent his time trying to get Ianto to crack. Other nights, however, were something of a free-for-all, with Jack dragging Ianto to clubs to pick someone to take back to Ianto's flat with them or going off on his own, crawling into Ianto's bed in the middle of the night after a hasty shower.

He hoped that New Jack was like His Jack, and would carry more than one swipecard. He doubted Gwen would have been able to train him out of that habit. She could barely manage her own, and her desk was atrocious. At least His Jack had been willing to try to keep his desk clearer, the prospect of extra blow jobs or other sexual favors keeping him at it.

Luck was with Ianto, because New Jack had three cards in his pocket. Ianto took one, slipping it into his own pocket, then put all his concentration onto the other task at hand: getting New Jack off as quickly as possible before the rest of the team noticed what they were doing on the CCTV and came to interrupt. He decided to play dirty.

Ianto shifted, placing his palms on New Jack's inner thighs and releasing his cock from his mouth. New Jack whimpered and raised his head. As their eyes met, Ianto held the cock in both hands and sucked on the tip. He bared his teeth around the head. New Jack jerked forward, thrusting into Ianto's mouth with a ragged cry, Ianto's teeth scraping against the sensitive skin. New Jack came explosively.

God, he tastes like My Jack, Ianto thought as he swallowed. He looked at the man in front of him, the sheen of sweat on his brow, the panting breaths, the excited smile.

"Wow," New Jack said. "That was great!"

"Wait until I fuck you," Ianto answered. "You'll see stars."
