Harry Potter gave a sigh as he looked at the empty space beside him as he lay in bed, just having woken up and put on his glasses.

Harry was a thin but slightly muscled twenty-nine-year-old man who was of average height, he had short, messy black hair, green eyes and he wore black, round glasses. He also had a lightning bolt shaped scar on his forehead.

Harry was currently in a sexual relationship with a man named Jim Gordon, a muggle cop who worked for the Gotham City Police Department alongside Harry. Harry and Jim were friends, however for the past two months they had been having a friends with benefits arrangement between them.

At the station they would act like friends would but whenever they were at either one of their homes, they sometimes would have sex. It wasn't a romantic relationship, it was just sex. The sex would be casual with no commitment, no strings attached.

This had been agreed upon after the first night they had shared a bed with each other. After work one night they had drunk together at a bar and went home together, they had decided to continue the sexual relationship.

Neither man was looking for something serious at the moment, both saw the sex as something fun to help destress and agreed that once they started developing any romantic feelings for each other that it would stop.

Each and every time after the night they started having sex, Jim Gordon would show up at Harry's apartment hours after their work, or Harry would show up at his, they would make out, have sex and then in the morning the other cop would already be gone.

Harry thought that he was fine with just having meaningless sex with the other male but lately he felt lonely and neglected whenever he awoke without Jim there. He realized that he had at some point developed romantic feelings for Jim Gordon.

Harry didn't know why he kept on doing this to himself if it was making him feel this way in the mornings but he didn't want it to stop either.

Harry went to the bathroom where he had a shower before getting dressed and getting himself some breakfast, shortly after he went to work.

During his day at work at the GCPD Harry found himself thinking that maybe he should just tell Jim that he wanted more from their time together. However, they both agreed that if either one of them developed romantic feelings for each other that this friends with benefits arrangement would stop. Harry didn't want to stop having sex with Jim though he couldn't deny what he felt for his friend and he hated the thought of Jim going to someone else for sex.

He ended up deciding that he would risk it, that he would tell Jim his feelings and ask for a proper relationship. The worst the other man could say is 'No' and then they would probably go back to being just friends and co-workers. Harry would be heartbroken, he was sure but he was certain that telling Jim was the right thing to do, even if Jim didn't feel the same way in return.

It took Harry maybe a couple weeks to ignore his doubts and fears before he even made the slightest attempt at speaking to Jim about it.

One night when Jim and Harry were going to have sex instead of them going to Harry's bedroom Harry asked the other man if they could talk.

"Sure" said Jim. "What about? Are we still going to have sex?"

"We can if you want to Jim, I just want to talk to you about something first"

Jim Gordon gave a nod of understanding and Harry invited the man to sit upon his couch.

"So, what do you want to talk about?" asked Jim, staring at Harry as Harry sat down beside him on the couch.

Harry blushed slightly as he stared at Jim, "I..I have developed romantic feelings for you and I want you to be my boyfriend"

Surprise filled Jim's eyes, "You want a proper relationship with me? But that's not what we agreed upon Harry"

Harry was silent for a brief moment before he gave a nod, "Yes, yes I do Jim and I know. I know that if we developed romantic feelings that this friends with benefits thing between us would stop but I just thought I'd tell you anyway."

There was silence again, silence while Harry stared the man who had been his sexual partner for months.

"Can I give this some thought?" Jim said at last after minutes of silence but that felt longer to Harry.

"Yes, of course" said Harry quietly.

Jim appeared uncertain and serious as he then thanked Harry and soon after left to most likely put some serious thought into what he had been told.

Soon after Harry still sat on his couch, wondering if he had done the right thing and hoping that the next time he saw Jim the other cop might want to give a proper relationship with him a chance.

What Jim had said had surprised Harry, he had expected Jim to just reject him and tell him that they would only be just friends again but it appeared that Jim was actually going to give it some consideration.

Hopefully Jim felt the same way that Harry felt for Jim.

XXXXXX

Jim Gordon gave a frustrated sigh as he sat at his desk at work.

Jim was a man in his thirties, he had short dark brown hair, he was fit and had dark blue eyes.

He worked as a cop at the GCPD and while his job was stressful and gave him much to be frustrated about his sigh of frustration wasn't about work.

Jim averted his eyes from Harry as he saw the other cop walk past his desk. Harry blushed slightly as he walked past him and it seemed that he was doing his best to ignore Jim, averting his eyes as well.

Last night when he had been with Harry the other man had confessed to him romantic feelings towards him and told him that he wanted a proper relationship with Jim.

This had been a surprise to him as he had been sure that Harry, besides friendship, had only felt physical attraction towards him and outside of their time together at Harry's Gotham home were just friends and co-workers.

Jim had promised Harry that he would give the request for a proper relationship with the other male some serious consideration and that was what he was going to do.

Whenever Jim had a moment to spare the rest of the day, he thought about what he wanted, he thought about his relationship with Harry and how he really felt about his co-worker.

Harry was a good man, this was something that Jim was well aware of. He was attractive, he had beautiful green eyes, a good body, an interesting and unique scar on his forehead. Harry was also quite a polite and kind person though he was also confident and was good at his job.

Jim liked Harry but did he want a proper relationship with him?

Jim tried to imagine what it might be like for Harry to be with someone else, anyone else. He tried to imagine someone else kissing Harry, someone else making love to Harry, he tried to imagine Harry dating someone else. He found that he didn't like it, the very thought of Harry being with anyone else in any kind of romantic way made him feel angry, it made him feel jealous, it made his heart ache.

Jim decided that he wanted to be the only one to touch Harry, to hold him, to kiss him, to make love to him, to one day tell him the words 'I love you'.

A smile appeared on Jim's face as he thought how he felt whenever he was with Harry, how good Harry made him feel and not just when they had sex either.

A couple of days after Harry had confessed what he wanted to Jim the man approached Harry just as work was ending for the day.

Harry smiled a slight smile when he saw Jim, "Hey Jim, have you thought about it…you know…um about us having a proper relationship?"

Jim nodded and he closed the distance between them so they were very close together. "Yes, Harry I have. I want us to be a couple if you haven't changed your mind"

"I haven't" Harry said in response.

Jim then pulled Harry into a kiss, a kiss that was full of the feelings he had for Harry. It was a gentle kiss for a brief moment before turning passionate. After a moment into the kiss Jim felt a satisfaction fill up his insides when the other cop returned the kiss and pulled him closer to him.

Afterwards Jim walked with Harry out of the police station, hand in hand as they left their place of work.

A couple of days later Harry and Jim went on their first date together at a restaurant as they began their relationship together as a proper couple.
