Jack knew what he was doing the moment he'd said it would be okay for them to have just one night together. Truthfully, Ianto's kiss had caught him completely off guard. He loved to flirt and tease the young man but he wasn't that kind of guy - or so Jack had thought. He'd assumed Ianto was as straight as they came, and he'd never bothered to ask if he'd ever peeped over the fence before Lisa had come along. Ianto really was full of surprises.

He probably should have been firmer and just canned the idea altogether, but they'd both been through hell and Jack was sure that come the morning, Ianto would probably regret it, or if not, at least apologise for the temporary lapse in sanity. Not that you had to be crazy to want to kiss Jack. He liked to think he just had one of those faces.

The trouble with the whole thing was not so much that Ianto had a sudden desire to snog him as it was Jack wanting to know what it might be like. He'd always considered Ianto nice to look at but not for him. Jack had developed a keen sense of when he could try it on and get away with it versus knowing it was a fantasy and nothing more. Tonight however was proving to be surprising on multiple fronts. Maybe it was wrong to take advantage of Ianto like this, but then again, maybe he was the one taking advantage of Jack's empathy. They were both consenting adults after all.

It was hard to pretend he didn't know the way to Ianto's apartment. He'd only driven past it a hundred times trying to see if he could spot a tell tale light in the tiny windows signalling he was home and safely tucked up for the night. Not that Jack was making a specific trip to check on him, but if he just so happened to be in the neighbourhood…

Most nights he couldn't see anything and had just assumed Ianto was already in bed. He hadn't expected to find out that Ianto was at the pub, still on the clock investigating the missing people that Jack and the rest of his team had been too busy to notice. It was probably lucky he'd resisted the temptation to go knock on the door and say hi. If he'd found Ianto not at home, he might have panicked and worried. Still, maybe he should have. They might have teamed up to solve the case and not come to blows over it instead.

There was still a chance they could put all of that behind them now, Jack thought, as he pulled the SUV up out front of the short apartment block, letting the engine slow to a purr and then off altogether. Then again, Ianto might have come to his senses by now and realised his mistake. Instead Ianto raised an eyebrow at him. 'Coming?'

They were barely through the door before Jack felt Ianto grab a fistful of his shirt and tug him forward. With practiced ease, Jack let his lips find Ianto's. He was a little taller than Jack was used to but that was okay. It was nice having someone match him for height. He let Ianto take charge because this was his idea, and Jack was happy to just give in and let it happen. Fantasies didn't usually work out like this.

It was a long time before Jack was allowed to come up for air, by which time he was very firmly pressed between Ianto's body and the hallway wall. He had to gasp just to get his breath back but didn't get long for it before they were into round two.

Where had Ianto learned to kiss like that? Jack had kissed a lot of people, but this was definitely up there. He kissed like a lover rather than like a one night stand. Maybe that's what Jack felt so drawn to. One night stands were Jack's speciality so having someone invest something a little bit more emotionally driven was nice. It was like he actually wanted Jack, not just for the sex.

What Ianto had excelled at in the kissing department was offset against the fact that he was clunky and fumbling with the rest of it. Totally forgivable of course. Finding your way around a new body took some time getting used to and even Jack wasn't perfect when it came to that. Sure, he bragged about it, but every encounter was different and new. They were bound to end up in a clumsy tangle more than once.

Where he could, Jack used his hands to guide himself into a more relaxed grasp, letting them slide down Ianto's back until he had them very cheekily cupped around his slim buttocks. That kept Ianto close and if he had a problem with Jack groping him he certainly didn't voice it.

With a bit more confidence as to what was where, Ianto's hands moved up as Jack's moved down, resting on his shoulders for a bit as they confined to kiss, and then sliding them under Jack's braces, slowly working them off his shoulders. Jack let go just long enough to snake his arms free of them before resuming his hold. Ianto's fingers toyed with his shoulders, fingered his collar and traced patterns along his jaw without breaking off, and then began slowly working on the top button of Jack's shirt. One by one Jack's buttons were deftly undone and Ianto's hands slipped inside between the layers of fabric, getting a better feel for what lay underneath.

He'd stop soon and Jack would be okay with that. There was no chance of them going all the way. Ianto would lose his nerve, or simply realise that what he wanted wasn't this. Kissing was one thing, but the rest was something else altogether. It was easy to confuse it with wanting someone.

Jack gave in to all of it, shirt sliding off him completely before Ianto clumsily attempted to remove Jack's t-shirt as well, before realising he'd need Jack's complicity in that action. Jack used the opportunity of raising his arms over his head to momentarily take charge, wrapping those same arms around Ianto's neck and giving him as much tongue as he could. He tasted beer and whisky and the salty remnants of packet crisps. It was a reminder that Ianto was just a wee bit tipsy and maybe not entirely as in control of his decision making as he might normally be. Jack would stop before he got too drawn in. He didn't want to take advantage of a friend.

Ianto suddenly pushed him back, breaking them apart and Jack sensed that Ianto had come back to his own senses. He looked down at Jack's naked chest and the belt buckle that Jack hadn't even noticed had been worked loose. He was looking very debauched for someone who usually held the upper hand. This was the part where he got kicked out, left standing in the foyer with half his clothes trapped on the other side of the door. Wouldn't be the first time. Sure as hell wouldn't be the last either. So why did he suddenly feel a wave of disappointment?

Ianto fixed him with a troubled look. 'Are you just going to stand there or are you going to help take these clothes off?'

Oh. How many times was Jack going to misread the signals tonight? He really was losing his touch. He took two handfuls of Ianto's shirt collar and yanked him forward, mouths mashing together in a painful and awkward fashion.

Lead me not into temptation, Ianto Jones, for I fear I don't know the way back out.
