I wrote a bit of porn. It's short, and not terribly polished. It's Jack/Ianto, and it has explicit watersports. It's not really part of a larger fic or anything. It's just something I felt like trying, and it really wouldn't fit in the sequel to the D/s fic.

The porcelain was hard and cold under Ianto's knees. The muscles in his hips and legs were already straining from his cramped position in the bathtub.
"Lean back," Jack said. "It'll make less of a mess."
Jack was towering over him, fully clothed with his arms crossed. Ianto was naked, and cold. He leaned back on his heels until his head was against the tile wall. He tried to keep his hands still at his sides, but it was so hard not to squirm and tremble.
There were so many things in his life to be scared about, things that kept him awake sometimes. And there were so many times when he came back to the Hub after a mission with his suit stained with alien blood and guts.
So, honesty be damned, he wasn't going to tell Jack that he was nervous. He was too proud for that, but also, he'd come to like the rush that came with letting Jack do these things to him. And anyway, Ianto's cock was pointing at his chin, hardened by the thought of what was going to happen. Sometimes, Ianto felt like their sex life was a series of dares and challenges. He hadn't brought the stopwatch home tonight, though truthfully he couldn't imagine a use for it.
Jack unzipped his trousers and pulled out his cock, level with Ianto's head. Jack was getting hard, but he wasn't too hard for the job.
"Any second thoughts?" Jack asked.
Ianto shook his head. "No."
"You sure? Once I start..."
Ianto squirmed. "Would you start, please?"
"Be patient," Jack said, raising an eyebrow, "or you'll give me performance anxiety."
Like Jack ever had performance anxiety. Ianto rolled his eyes, and then closed them.
A moment passed, and he felt a warm stream on his chest. Jack had promised not to aim at his face, but Ianto closed his eyes tighter, lifted his chin, and sealed his lips. The piss ran down his front, over his own cock, and down his thighs.
He'd been holding his breath, and finally he let it out in a short gasp before shutting his mouth again. Slowly, he opened his eyes, and took in the sight of Jack in front of him, feet shoulder-width apart and his hands aiming his cock.
"You like that?" Jack murmured. "You like being marked?"
Ianto closed his eyes and shuddered. His cock twitched, and he rubbed it with one hand. A year ago, it would have seemed mad, enjoying being pissed on. He didn't care. He was going to come so easy and so hard when this was done.
It was over in seconds, probably. Ianto couldn't tell. Perhaps he should have brought the stopwatch, after all.
Jack reached out and ran a hand through Ianto's hair.
"Oh," he said. "That got me so hot, Ianto. You don't even know." Jack idly stroked his hardening cock. There were still drops of piss on the head. "Would you like to lick it clean? It won't hurt you."
Ianto hesitated. He started to open his mouth, but stopped, pulling back.
"That's all right," Jack said. "Maybe another time?"
Ianto nodded. "Yeah. Next time."
