Hi, everyone! This is my first submission here. My very own House fanfiction. Hope you enjoy the reading and if you wouldn't mind leaving me some reviews, just so I know where I can improve. Further chapters will be added soon! Thank you very much.

Three knocks. That's all it took to inform him who was waiting outside his front door. But for a split second he wondered whether it was who he suspected or not, since the knock was far from familiar. The knocking almost sounded cheerful, whereas it should have sounded serious, dull, and business-like. But then again, who else would be visiting him? He sighed as he limped slowly towards the door, while resting his body against his cane. When he opened the door, his piercing blue eyes faced indeed a new face.

"You're not Monika."

He stated simply, looking at the awfully young woman before him; perhaps too young to be legit. She was wearing a long leather jacket that prevented from showing anything but her neck skin and her high-heeled shoes. Her long, wavy hair rested upon her shoulders as it burned a powerful colour of red; it couldn't be her natural colour, he thought. Her eyes were green, almost just as rare as his, since they had a slight shade of grey. She was resting against the door with a hand determinedly situated against her hip as she watched him with an eager smile.

"No, I'm not. The name's Kat. But if you want Monika or someone else I can go. No biggie."

"Are you legal?"

"Are you asking me if I'm still a minor? I just turned 21 last month."

"Then you can stay."

He stated on a cold tone, without much affection, before he opened the door more widely to let her come in. She silently tiptoed into his living room at the same time unbuttoning her jacket and letting it slide on the floor. By the time he turned around to face her, she was only wearing her lingerie: a black sports bra and a lace thong which had attached to it her port garters. She didn't say a word just looked at him as if asking "what are you still waiting for".

He didn't say anything either, because he felt no need to do so. He walked towards the couch, threw his cane on the floor, before he finally sat down, with his legs spread wide open. She tenderly bit her lower lip and looked at him with a pair of mischievous eyes before kneeling down in front of him, as her hands were already unzipping his pants. He was still soft, but that didn't matter to her since she knew how to intrigue him. She tugged his pants down, wishing to remove them completely, but suddenly one of his hands prevented her from revealing more than his upper thigh. She didn't ask why, after all it was the customer's choice.. She took his member into one of her hands, while her thumb rubbed against its shaft slowly. She looked up at him and asked simply:

"What do you want me to do?"

"The full deal."

He replied, nonchalantly, as he focused on her breasts that were beautifully cupped in that bra of hers. He groaned, more likely to himself, as he felt himself slowly hardening. Fact which she felt also. Just as she was about to tuck his boxers down, an alarming noise pierced the silence that was echoing inside the living room. His phone rang furiously, startling them both as he sighed annoyed, before finally setting the phone on speaker.

"This better be important."

"House, we've got a new case," said a young male voice, with an Aussie accent, from the other side of the phone, without sounding too worried.

"Not interested right now. I'll be down at the hospital in an hour. Can't it wait?"

The last thing he needed now was to be disturbed. He just needed release, not arguing with some voices that came from a speaker. Kat seemed to understand perfectly, and even though she assumed she wasn't allowed to, with a snickering smile her hand started rubbing his erection slowly, making it firmer. House looked at her, as if she were insane, but did not do anything to stop her. After all, he couldn't say a word.

"House, are you still there?" Another voice, this time a female one, was heard, fact which annoyed him even more. He couldn't possibly concentrate with Cameron on his mind. The hooker kept on massaging him, while her fingers caressed his balls, intriguing him even more. That made him gulp silently.

"Yeah, still here."

"Madeleine Sears, 37-year-old Caucasian female, married with no kids, was brought in here today complaining about pain and weakness manifesting in her knees, ankles, shoulders, toes, wrists, neck and back." Chase's voice informed of what they had gathered so far in regards to the patient.

"Fascinating story," he stated ironically, as he rolled his eyes. "You called me for weak skeletal structure? It's probably just a deficiency of calcium."

He wished to share more of his annoyance, but his tone was instantly shut off by the fact that Kat, down there, had just swallowed him hole, her wet and red lips lingering all over his cock. He groaned, this time in pleasure mixed with annoyance, as his eyes widened in fear of not getting exposed.

"There's more", Foreman stated. "She says that it initially started with pain only in her left knee, and in time the pain had extended to the other areas."

House was struggling to pay attention to whoever was talking, but there was no wonder why he had difficulty in actually doing so. Her widely opened mouth surrounded his erection entirely, as she went forward and backwards, slowly increasing her pace. While her tongue was swirling daringly around the head, she felt for the first time the salty taste of his pre-cum. At the same time, he leaned his head backwards, letting it rest on the back of the couch, as he tried to release his short breaths of ecstasy as silently as possible.

"S-so we assume whatever it is, it's expand-ah!" he groaned surprised, way too loud for his cover not to be blown – no pun intended – because of the feeling he received from her teeth scratching slightly against his cock. Her eyes looked up at him, just as his were staring down at her, watching her smile kinkily with him in her mouth.

"House, are you alright?" Cameron's worried voice was heard again.

Mumbling, for he was almost out of breath due to him repressing his own moans, House stated simply: "Y-yeah. Never m-mind me. Is it viral?" he asked finally.

"We tested her and it came back negative. We assumed it could be anaemia, but it's not neurological either: the blood tests prove otherwise." Foreman's voice added, trying not to sound interested in what was happening with House.

The girl in between House's legs was enjoying this more than she should have. Her lips were dragging themselves against his massive cock, back and forth while her teeth dared to scratch at his balls as well. Her tongue was restless, continuously wetting the member, giving gentle strokes, as she purred teasingly.

House's hand went to caress her red hair for a moment, not before pulling at it roughly, just to hear her moan softly. He was close to his release, but he couldn't do it in front of an audience. With a grunt that responded to her moans, he wished to end the conversation.

"S-start her on calcium and morphine, to ease the - he groaned due to too much pleasure, ecstatically mentioning the following word - pain. I'll be back in an hour."

And with that he hung up on them without waiting on their probable response. He looked down at her, and struggled to warn her about him coming shortly.

"Uhm, y-you c-can stop since I think I'm about to…" he whispered, not even being able to formulate his thoughts right. It just felt too good to be true and he couldn't concentrate on such trivial matters, such as explaining a hooker what was about to happen.

Kat was very well aware of the fact that she should stop, since if she didn't, she would be paid only for the blowjob, and not the whole deal. But for some reason, she wanted to taste this man more than ever. And she assumed he wanted to feel good up to the very last moment, therefore, she ignored his words. By this time, she had her eyes closed, her movement being as persistent as it could be, while her fingers were playing with his balls. When she gave signs of retreating, her last and final tease was to pull her teeth across his cock, not before nibbling slightly on his head. This instantly made him let go entirely, coming into her mouth without any possibility of going back. House growled too excited to give a damn about anything else at that very moment, as his cold sweat covered his entire being.

She licked with the tip of her tongue the come that dripped of her lips, as she finally pulled out. Her eyes were fixed upon his figure, feeling proud of her accomplishments, before swallowing the sticky white texture in her mouth, eventually licking her lips to clean herself up. He watched her while panting heavily. It took him several minutes for him to be able to say a word.

"You're good. Better than Monika, actually," he was surprised by his own words, since it wasn't in his nature to compliment a prostitute on her job.

"He he, I know." She stated simply, without any hint of doubt in her own talents. "Guess who taught her how to do this?" Kat winked at him, before she finally stood up on her own feet.

House looked at her as if indeed she were too good to be true. All sorts of thoughts were coming back to his head, but he still wished to enjoy the little bits of joy he received from her. He closed his eyes, and rested his head back against the couch, trying to calm his breath. There were so many questions left unanswered, but he knew better than to start a conversation with a hooker. That until she broke the silence.

"Listen, I was thinking," but she was rudely interrupted by his grouchy tone, "Oh, you girls also think these days?" He was coming back to his old self, and even though his comment was rude, Kat was not bothered by it whatsoever. "Not all of us. But I do. Which is why I wanted to ask you whether you considered a possible infection, either parasitic or chemical, for your patient?"

House raised his head, his look piercing her entire being. For a short second, she could almost feel embarrassed, but she struggled as much no to show her body shivering. He pulled his boxers and pants back up again, and eventually got up, limping towards his cane.

"Somebody's a doctor as well, during their time off as a hooker, eh?" House replied with an ironic tone, before returning towards her.

"Not really, I was just sharing my thoughts."

"Well don't, you're not paid for that."

"It could be possible that she was exposed to toxic chemicals or even heavy metals." Kat ended, because she realised that he was right, she was pushing the line. "You're right. Let me finish my job." She continued, but House replied immediately after. "There's no need to do anything more. You're dismissed."

"But you said you wanted the full deal."

"I did; that until I received a call about a patient." But it wasn't necessarily that. He was already intrigued by the fact that the girl in front of him had suggested something that he had yet to take into consideration. And it bugged him that he didn't come up with the idea first. How could a hooker come up with that?

"Okay, very well then. You don't have to charge me for the swallowing: that was my pleasure." She stated simply, before winking at him once again.

She bent over so she could pick up her jacket, and before you knew it she was already dressed. House looked at her suspiciously.

"Yeah, for some reason I doubt that." But he took his wallet out and paid her anyway.

She gladly received the money and without adding anything else, she headed out the door. House, on the other hand, remained still in his spot, meditating. His mind was being bugged by two things: how could a 21-year-old give such good blowjobs, and also swallow at the end, and how could a hooker have any medical knowledge, and even worse, how could she have come up with something he did not?

The world is a curious case.

Hope you enjoyed the reading!
