Sebastian woke up alone, and slightly earlier than usual. He groaned as he sat up, feeling just a bit sore, but he got to his feet and didn't bother to get dressed before he descended one floor and opened Moriarty's bedroom door.

Moriarty was lying in the middle of the large bed, the sheets tangled around him as if he'd been tossing and turning. He was still asleep, but his eyes were moving under the lids.

Quietly, Sebastian closed the door and went to the other side of the bed. He had to move Moriarty's arm aside to lie down and then shifted closer, until he lay on his stomach with an arm over Moriarty's stomach.

He closed his eyes and lay like that for a while, but soon he found he couldn't drift off again. Moriarty seemed to have returned to a deeper sleep, so Sebastian withdrew his arm and quietly opened the drawer next to him. He smirked. Of course there was lube. He wondered if by now there was one drawer or cupboard in this house that didn't hold a bottle. Needy Kitten.

He sat up and lubed his fingers, then pulled the sheets a little off Moriarty and gave his soft cock a few strokes before sliding his hand behind his balls.

A sleepy grunt turned into a ragged moan. "Tiger?" Moriarty muttered.

"Yes, Kitten?" Sebastian looked up and grinned, circling Moriarty's hole with a fingertip.

Moriarty's hips bucked a little. "Please..." he groaned. "Do it..."

Sebastian chuckled and pushed his finger all the way in, then started thrusting slowly.

Moriarty moaned and rocked his hips. "More," he whined. "I need more..."

Sebastian felt his own cock stir, wanting to push into him, but he pulled back his finger and inserted two, curving them and thrusting hard while he started stroking Moriarty's cock.

Moriarty seemed content for a while, then pleaded for more again.

Sebastian added a third finger and didn't hold back now, fucking him hard with his fingers while squeezing and tugging his cock. "Come on, Kitten... Just let go..."

Soon Moriarty was thrashing and practically screaming with pleasure. As he came, he clenched hard around Sebastian's fingers.

Sebastian tried not to think about having his cock there instead and just watched Moriarty's face. When he relaxed, Sebastian pulled back and disappeared into the bathroom to scrub his hands.

By the time he returned, Moriarty was asleep again, his mouth slightly open. Sebastian wondered how he'd react if he just fucked his mouth, but he still couldn't do that. He sank down on the mattress again and started stroking himself while watching his boss sleep. It was just one more day before they got the results. And fuck, he hoped they were clean. He couldn't wait to just pin Moriarty against the wall again and take him there. Or maybe he'd tie him up on the bed, completely helpless as Sebastian had his way with him, trailed his nails down his chest and spread his arse cheeks and... Oh yes. His hand sped up and he didn't even clean up after his orgasm, but just fell asleep there on his back.

...

"Morning, Tiger..." Moriarty murmured sleepily, wrapping an arm around him. Then he pulled away. "Ewh... Gross..." he cried staring at the dried mess on Sebastian's stomach.

"Hmm?" Sebastian opened one eye. "Oh..." He chuckled. "Morning, boss. It's not like you're much cleaner. Care for a shower?"

Moriarty groaned and got out of bed, moving carefully as if scared to touch himself. "You are such a pig," he complained. "And in my bed..."

Sebastian grinned. "I thought I was a tiger."

"A disgusting Tiger." Moriarty practically ran to the bathroom and jumped in the shower, not even bothering to let the water run hot.

Sebastian chuckled as he followed him. "Poor Kitten. Better clean yourself up nice and good. Shame you don't use your tongue for that..."

"I hate you," Moriarty huffed, panting from the cold. As soon as he was clean, he jumped back out, grabbing the largest towel he could find and wrapping it around his entire body.

"Didn't seem like you hated me that much this morning," Sebastian pointed out, lazily washing his chest.

"Well, you can't have your fingers inside me all the time, can you?" Moriarty snapped, heading for the door. Then he stopped and looked back at Sebastian. "You liked it, didn't you? When I did it to you?"

Sebastian shrugged and rinsed before he answered: "It was alright."

"Then you're up for trying it again?" Moriarty asked. "Once you've had time to... recover?" He studied Sebastian. "Are you sore?"

Sebastian groaned. "Can't I just have a shower in peace?"

"Nope." Moriarty giggled. "I want all the details."

Sebastian sighed and turned off the tap, then got out and grabbed a towel. "I feel it a bit, but nothing I can't handle. And I think you've noticed that I liked it. So yeah, if we've gotten bored of all the other options we can do it again."

"I'll look forward to it," Moriarty said, grinning.

...

"So," Moriarty said, leaning forward in his chair. "How bad is it? What's he got?"

Dr Sawyer frowned a little and sifted through the sheets of paper she was holding, before turning one and putting it down in front of them.

"I'm happy to say that Mr Moran does not have any infections as far as we can tell from these results."

Sebastian smirked. "Told you, boss."

"However," she continued, "as you have had unprotected sexual contact, he will need the same antibiotic treatment as you, Mr Brook." She put down another piece of paper next to the first.

"What?" Moriarty roared. "This is complete bollocks. There's nothing wrong with me."

"Well," Sebastian said, leaning over to read the paper, "except for a Chlamydia infection..."

Dr Sawyer nodded. "It's nothing to worry about. You told me you didn't have any symptoms and it's very improbable that there will be any remaining effects. But if your sexual partners have been infected recently, it is possible that the test does not show this yet, so they will need to be treated too. Is there anyone except for Mr Moran with whom you have had any kind of unprotected contact?"

Moriarty looked murderous again, but nodded. "There are... some..." he muttered through clenched teeth. "I'll let them know..."

"Very good," Dr Sawyer said, "though if you want to avoid awkward conversations you can always leave their contact details here, so that we can get in touch with them without needing to mention your name."

"I'll take care of it," Moriarty said, standing up. "Sebastian. Let's go."

"One moment, please," Dr Sawyer said, handing Sebastian two prescriptions. "The treatment is just one tablet. I advise you to take it as soon as possible. But to avoid re-infecting each other, it's best to wait a week before you resume your sexual activities."

Sebastian glared at her. "Another week?"

She smiled a little. "It would be best. If it's impossible, just be sure to use a condom. And if you both regularly see other partners, I'd like to see you both for tests more regularly. And definitely if you experience any symptoms, of course."

Sebastian got up and grabbed the papers. "Fine. I'll see to it that he remembers that," he said, looking at Moriarty.

...

Once they were outside, Sebastian cleared his throat and gave Moriarty a pointed look. "Scared I'd infect you, weren't you? Guess someone else did the job for me."

Moriarty avoided meeting his eyes. "Did you finish that list I gave you?" he mumbled.

"Yeah," Sebastian said, frowning a little. "Those eight people, right? I'm only not sure about the exact address of one of them. Fled to the Bahamas if I got it right. Are you telling me you shagged them all?"

Moriarty gave a single nod. "I'm going to need you to fly to the Bahamas and find Vigo. I'll talk to the rest."

"Uhm, I'm going to need a little more information on him if I'm supposed to find him somewhere on the Bahamas, okay?" Sebastian smirked a little. "But seriously... If those are only the ones you've had unprotected sex with... You're such a slut."

This made Moriarty glare up at him and if looks could kill, Sebastian's ashes would already have been scattering on the wind. "I didn't with any of them," he snarled. "Which means that the protection failed. Do you have a clever way of finding out which time it didn't work?"

"Calm down, boss," Sebastian said, smirking. "I think it's very good of you that you track them down to protect their health. Did you get in touch with Logan yet?"

"I didn't think I'd have to," Moriarty said. "We haven't done more than snog since... In a while..." He sighed.

"Better let them know anyway," Sebastian said.

"I will," Moriarty's look was a rather clear indicator that he had just about used up his capacity for calm conversation. "Take me home," he ordered, heading for the car.

Sebastian smiled and got in the driver's seat. He had had half a mind to let Moriarty drive on the way home, but now there was of course no question of it. And anyway, Moriarty looked far too thunderous and distracted to even just drive. He clearly hadn't expected that it was possible for someone of his power and genius to get infected by some stupid bacteria. It was almost funny, if it hadn't meant that Sebastian still couldn't fuck him.
