L and Light were both laying in their beds, handcuffed together. The handcuffs had made it hard to sleep for Light, the uncomfortable and cold metal rubbing harshly against his wrist with every small movement nearly drove him insane. He thought it was a ridiculous idea but had no choice; the percentage of him being Kira would go up by at least 5% if he had disagreed to the cuffs. Light tried to relax and get some sleep instead of worrying about L finding out and the stupid handcuffs.
However, L had.. other things on his mind. Although the cuffs were purely for the purpose of examing Light's behaviour for any signs of being Kira, L found himself blushing at the realization that he was handcuffed to the Light Yagami every girl at To-Oh University (and him, but he would never admit that) drooled over. The thought of being cuffed to his suspiciously attractive rival had him almost fangirling over Light. L tossed and turned in his bed, trying not to disturb him.
"L, are you alright? You seem to be quite uncomfortable, " Light asked, concerned and interrupting L's train of thought.
"Y-yes I'm okay just try to get some sleep Light.. "
"Alright then. Night, " Light muttered, turning to face the wall and lightly pulling on the handcuff, causing him to groan quietly.
L shuddered at the sound and looked down. Shit. He was hard from that? L's erection was noticible even in the dark due to the jeans he was wearing. <span;>Suddenly a wave of embarrassment had hit him. <span;>He looked over his shoulder to see that Light had turned around and L sighed in relief.
<span;>It would be awful and degenerative to.. relieve himself right here, while handcuffed to his enemy, his rival. Waiting for it to go down would be L's best option.
But it didn't. Goddamn it, he was now getting frustrated. L could feel his face heating up as he fought the urge.
Fuck it.
He slowly sat up and pulled down his jeans, being as quiet as possible. Although L knew this was wrong and disgusting of him, the fact that Light was only a few feet away only fueled his erection even more..
L then grabbed his boxers and shoved them down to feel the cold air hit his dick. It gave him chills as he looked over at Light again, and he had not moved. Probably sleeping.. L thought, and decided to not hold back today. It had been a while since he masturbated, and now it was just too hard to resist especially with Light next to him.
Suddenly, L started to carress the tip of his cock, imagining Light was doing it instead of him. L then started to stroke down, then up, gradually increasing the pace until he was panting softly, licking his lips at the unholy thoughts of Light popping up in his head.
A rustling noise. L gasped and stopped his hand when he realized he was being a bit too rough.. The clanging of the cuffs and rapid shaking of his arm must've woke Light. L looked mortified and prayed Light did not awake.
...
He could hear Light getting up and walking over to L's bed... He loomed over L, gazing at his surprising stupidity in this moment. Did L really think that after all that Light would not notice him jacking off in the same room as him? L made an attempt to cover up his dick, trembling arms hiding it and legs closing together as he buried his head in them from embarrassment.
As much as Light would love to degrade L and make him feel even more ashamed, the probability of him being Kira would probably go up.. So, Light sat down beside L and gently pushed his legs open again to find his cock still throbbing painfully. Oh God.
Light sighed before encasing his mouth around the tip of L's dick, staring directly into L's eyes with his own tired ones and a lustful look on his face. L whimpered as Light pressed kitten licks against his slit before lovingly peppering kisses all over it, gaining a moan from L.
L swung his hand over his mouth to stifle his moans and looked away, still not over the embarrassment from earlier. Light moved closer to softly brush his messy hair behind his ear before pushing L's hand away from his mouth.
"Don't. I want to hear all the lovely sounds you can make, L, ♡" Light whispered with a smirk on his face as L smiled back.
Light got back to teasing L's dick by licking stripes on it and humming in appreciation. The vibrations of his voice made L a horny mess, even though Light had not even done much. L must've been very sensitive.
He stopped licking it, hearing L whine at the absence not knowing what was coming next.
Light slowly placed L's hard dick in his mouth, gradually going lower in order to envelope the whole thing into his mouth. Finally, Light reached the base of his cock and starting moving up and down, like L's hand had done earlier. He sucked and licked all around L's cock, tears starting to form in his eyes from the size of it. However, Light still continued to pleasure L.
"Nghhh.. Light I'm c-close!" L said through breathy moans. Light picked up the pace, savouring his dick like it was the best thing he had tasted. L grabbed onto Lights hair, pulling him deeper onto his dick, overwhelmed with pleasure.
"C- I'm- Light, I'm coming!! AH!"
L thrusted into Light's mouth and let out thick white streams. They both lay on L's bed, still handcuffed, panting as L pulls out. Light, not knowing what to do, swallows despite the salty, almost sweet taste of L's cum.
"T-thank you," whispers L.
"It's.. alright," Light replies, replaying the event in his head and blushing.
"Light, the chance of you being Kira has gone up by 3%."
...
Light storms off into the bathroom cursing at himself.
