Sex Is Always Better When You're Angry

Nathan Petrelli just walked through the door to his apartment after a long day at work. He had recently gotten a job at a local sit down restaurant - a mighty step down from senator - but money nonetheless. He threw his coat on a rack by the door and methodically took off his shoes and placed them on the mat. He then made his way into the kitchen, where he found his brother stirring a steaming pot of something that smell incredibly good.
"Nathan!" Peter called from over his shoulder. He wore a ridiculous smile and apron over his usual tee and jeans. "I've almost finished making dinner, so go settle down and make yourself comfortable." Nathan sighed and turned back to the dining room. Ever since Peter had started staying with him again, he had insisted on cleaning and cooking meals for them both, considering all the trouble Nathan had gone through for him before, it was the least he could do. Nathan appreciated the sentiment, but really wished he wouldn't bother. Peter wasn't exactly the most talented in the kitchen.
Two minutes later, Peter came out of the kitchen carrying two steaming bowls of something. He set one on the table in front of Nathan and took the other to his own place on the other side. Nathan looked down to discover that Peter had made them Campbell's Chicken Noodle Soup. Nathan was somewhat impressed. That was high maintenance for Peter. That sat for the next ten minutes sipping at the soup, talking idly about how their day had been. Peter had been to a job interview with no luck. Nathan had dealt with a very grouchy elderly couple. But the seemingly bad day hadn't ruined Peters good mood, which was odd.
"What, did you get laid?" Nathan had asked jokingly. Peter however had become a little embarrassed at the change of topic.
"Well, no.." Peter had started. Nathan listened intently. If his brother had a new girl, he might be able to get over that Irish one he claims he lost in the future. "Not exactly. I...I went to a meeting, and well..." Nathan began to scowl. What was he talking about? Peter must have noticed, because he began to get defensive. "It's not a big deal. I mean, I'm beginning to understand myself a lot better. I mean, I've opened up a whole new avenue. It makes me happy. Is that such a bad thing? Is the only way I can be in a good mood is to get fucked? Jeez, Nathan!" Peters defensiveness grew to anger and he stormed out of the dining room in to the spare bedroom, refurnished for him. Nathan sighed and finished his soup, thinking about how all their conversations lately had turned to this.
Nathan had wanted Peter to find a girlfriend, or anybody really, to get his mind off of what had happened. Peter had refused. Vehemently. Nathan had only hoped that maybe Peter was moving on. He wasn't lost in thought about the girl anymore, that was an improvement.
Nathan sighed again and gathered the dishes, washing them in a few minutes and cleaning the counters off. Throughout this time, his patience for Peter was slowly whittling down to nothing. By the time he had finished cleaning up dinner and Peter hadn't left his room, Nathan was fed up with it. He threw open Peters door angrily to find Peter sitting cross legged on his bed, brooding as usual. Coincidentally, his brooding included zapping random parts of the wall. There was one wall that was mostly black from the abuse. He didn't turn around at Nathans entrance.
"Peter!" He turned. Nathan stood in the doorway, his fists clenched. Peter was unperturbed. A thought slowly entered Nathans head as the two stared at each other. A way to get Peter off that high horse of his. "Peter, I think I AM right." he said quietly, stepping into the room. "What you need is a good fuck." He was in front of Peter now, who looked up at him quizzically, doing that adorable eyebrow arch that always threw Nathan for a loop. Not this time. This time it made him hard in the most enraging of ways. "And if you're not going to take the initiative to find someone yourself, then I guess I'm going to have to do it."
Peters eyes got wide, but before he could say anything against it, Nathan was on top of him, one hand over his mouth and the other fumbling with the zipper of his pants. Nathan noticed that, although Peter could throw him off with one little thought, he did nothing to stop what was happening. Nathan got the zipper undone and whispered harshly in Peters ear, "You'll enjoy this little brother, I promise." The feel of breath on his ear made Peter shiver uncontrollably. He felt himself get harder by the second. Nathan took his hand off the Peters mouth and kissed him hard, forcing his tongue between his brothers lips, practically gagging him.
He turned Peter quickly onto his stomach, holding him down at the back of his neck while he undid his pants and pulled down his brothers. He stroked his throbbing dick lightly. He considered stretching Peter first, but decided against it. He wanted him to feel this. He wanted it to hurt. Instead he licked his fingers and rubbed his tip a little, which would make it a little easier for him. He rubbed Peter a little bit too, a kind of warm up. When he deemed it time, he pushed himself completely into his brother with no warning.
Peter was utterly unprepared. He gasped and clenched his muscles tightly around Nathans cock. Nathan only pushed harder, causing more pain. He then began to move out and thrust back in. Peter couldn't help it, he felt himself pushing back. For reasons he couldn't think of at the time, an animal urge, he wanted Nathan to come inside of him. This may have been a sort of punishment for him, but he wanted to prove that he had some power over his brother too. If he could make him come, he would have his own kind of victory. With that in mind, he clenched his muscles harder, and pushed more against the raging extension inside of him.
They became a rocking mass of body, connected in the most intimate of ways. They moved in a fluid motion, perfect harmony. They we both sweating from the exertion, and Peter was rather uncomfortable in his position, but couldn't will himself to break away. He eventually felt that he was about to come, and held it in as long as he could before he finally had to release, dribbling all over his bed sheets. Nathan gave one last thrust before pulling out.
He pushed Peter completely onto to bed, where he lay shaking and gasping and zipped his pants back up. "I hope you learned your lesson," he said smugly before leaving the room, thoroughly satisfied.
