Light angrily stormed into the bathroom, cursing out his whole existence. He never imagined that L would show up to his college, much less challenge him to a game of tennis in front of everyone. Light was glad he won. He wanted everyone to know he was better than L, that stupid bastard.
Light yanked his clothes off, finding that thinking about L got him a little too... excited. It was not Light's fault that L happened to be rather attractive. Light hadn't masturbated in a few days, and he decided to blame his erection on that. He refused to think about the implications of finding another man sexually attractive. Light was sure he liked women. He liked their breasts, the ways their hips wiggled when they walked, their dimples, their crooked teeth, and the fact that most women in Japan didn't have a penis.
Light liked his own penis. It was rather nice, performed its duty well, and brought Light pleasure beyond his wildest dreams. However, liking his own penis was very different than liking another man's penis. Light had seen other men's penises before in the shower room and bathrooms, and he had never really thought much of them. He wondered if it was because they weren't as pretty as L.
Actually, when Light had seen L, he hadn't been thinking about L's cock. He'd been thinking about his hair flopped around when he ran after the ball. He'd been thinking about how hot it was when L's lips parted open for the quickest of seconds when he was thinking about his next move. L had been clever, frustratingly so.
Light hated being horny and angry. He wasn't sure if he'd benefit more from throwing things around or jerking himself off in the shower while praying no one decided to shower today. He could simply take a warm shower and let that take care him, but he hated doing that. People were calling him a God. What kind of God uses water to cure their erection rather than let nature take its course?
He turned on the water, letting the warm droplets trail down the skin of his back. He turned himself around, trying his best to hide his penis from the view of the doorframe. Masturbating in the shower was risky, but getting caught by the wrong person could be bad. He didn't want to be known around campus as a filthy pervert who masturbated in the showers. Light had been raised with strict rules, and his father would blow a fuse if he found out Light acted indecent in a public restroom. Light, too, would be extremely upset if anyone else found out. Light had worked very hard to build his reputation, and he preferred it not to be ruined due to getting horny over the first person to truly challenge him.
He slowly began rubbing his penis, careful to go slow so he could savor the moment. The guilt of masturbating in a public restroom would haunt Light later, so he needed to make the sensation worth it. He slowly continued rubbing himself, wishing he was home so he could hump his pillow. It wouldn't be quite as good as fucking L's round, slightly fat ass, but that would be as close as Light could get. He highly doubted that even if the detective decided to randomly have sex with Light (which Light would have to decline on the account of his wavering heterosexuality) that he would let Light top.
The thought of fucking L, of showing him his true place in Kira's world, filled Light with a burning sensation in the pit of his core. L's proper place was beneath Light, on his hands and knees begging for mercy. Light continued jerking his penis to the thought of L crouched down on his hands and knees, a dog collar wrapped around his throat. L would look so beautiful with Light's cum on his face and tongue. He momentarily paused, wondering why he got so excited by the idea of having utter control over L.
One of his former classmates, a fairly decent communications major, never got Light this excited. Whenever Light had thought about fucking Takada, he figured it would be a fast and quick thing. He never actually got around to fucking her, finding that she was ultimately not a match for him, and Light didn't see the point in wasting time if he was already over her. He imagined that if he had gotten around to fucking her, it would have been a very quick affair with no sexual fetishes— or, at the very least, not to the extent Light was thinking about now. Now that he was thinking about it, when he thought about having sex with women, it was a monotone affair, an expected thing. He was expected to have sex with women. He knew nothing further about female anatomy other than the fact his penis could either go in the vagina or anus. It was selfish of Light to not care any further. He was so uncaring that he never even bothered to read up on how to give a girl an orgasm, nor had he even bothered to search out that sort of porn.
It was easier with L. Light didn't have to worry about L's sexual pleasure, in part because they would never actually fuck and in part because Light would fuck L to dominate him rather than give him pleasure. He wanted L on his hands and knees, panting as his semen trickled out of L's worn hole (because Light would have fucked him so much and so rough). He wanted L to surrender to his harsh words, to his conquest and brutality. Light wasn't gay, but the thought of dominating L was hot. Light was positive that if L were a girl, he'd want the same thing.
Although, he imagined that if L were a girl, the urge to strap her to a wooden table in a straightjacket so Light could roughly fuck her throat and make her lick Light's asshole would be nonexistent. It was different because Light and L were men and meant to be rough. If L were a girl, Light would keep her in a cage still, but only because beautiful things run away. He would want to show her to the world but be the only one to ever touch her and see her vulnerable. In a way, Light held traditional values about how women should be treated. Light was almost glad L wasn't a girl.
But fuck... the thought of L's pretty little face held in place by bondage, unable to move his limbs due to the straightjacket, was causing Light to almost crawl out of his skin. His beautiful pink tongue, dangling out of his mouth, seeking out Light's rim. Fuckfuckfuck—
His cum squirted on his hands, chest heaving with effort Light didn't realize he'd been using. Everything had felt distant, almost unreal. He hadn't thought he'd actually go through with it. But now, with the burning in his stomach subsiding, he knew it'd been inevitable. He let the water wash away his semen, the traces anything happened quickly going down the drain.
The door opened, revealing the devil in the flesh. "Mind if I join you?"
The water had washed away his sins, allowing Light to seem innocent. He figured L had similar fantasies, albeit with the roles being reversed. Regardless, Light did prefer L not to see him masturbating in the shower.
"Not at all." L may not have been a girl, but if Light had it his way, he would eventually cut off L's wings and keep him in a little cage. "Please, join me. That was a good game."
It had been a good game, but the real game was just beginning.
