Lavi was rather..intrigued with the way things were going.
Allen hadn't said a word. He merely woke up, pulled some clothes on, and reported their progress to Komui the first chance he'd gotten, without paying so much as a second glance at Lavi.
Was he angry with Lavi? Probably.
After all, Lavi did take his virginity..with little to no permission..
But Allen was enjoying it, after a while! That had to count for something, right?
"Allen.", Lavi purred, sitting across the absent minded boy on the train, "How's your body?"
He noticeably hid his blush, "I-It's fine! Just.."
"It's sore, isn't it?", Lavi smirked as he leaned in, inspecting the skin.
As hoped, he'd left a few marks here and there, along with a fairly large hickey.
What he would give to get a good look at the rest of his body..
"Lavi?"
Well, that would just have to wait.
"Yeah?"
"Why..Why did you do that?"
"Do what?"
"Y-You know..", his blush increasing as he turned his head the other way.
Lavi noticed, placing a hand under the soft chin, guiding Allen's eyes to meet his own, "Why else?"
"Why..Why else?"
"You're mine, Allen.", he whispered lustfully, leaning into the skin until he nuzzled into his neck, "You're all mine. Don't forget, alright? No one else is allowed to see your beautiful body.."
"B-But.."
"No one.", he snapped, "Just me. Everything..Everything from now on, it's just me."
"Just..you?"
"Exactly.", he grinned, "And as long as you've got that memorized, you and I will be just fine..In fact, I may not even have to punish you for getting dressed without my permission."
"W-Why would I need your permission to-!"
"Why? Isn't it obvious?", he sighed, "Sometimes you can be so dense. Did you ever consider..I don't know, maybe I wanted to go for round two?"
Allen huffed, turning away.
"By the way, Allen. Next time..try putting up less of a fight. It'll make things a lot easier."
The harassment continued at the order.
Thankfully, when nobody was around.
For instance, as soon as Allen had finished a conversation with Lenalee, as soon as she'd left, Lavi pounced.
"L-Lavi!", he screamed as the boy began attacking his neck, "N-Not here!"
"It's fine.", he grinned against the skin, "No one will see us..and besides, if that's what you're worried about..", he coyly tugged on his own scarf.
Allen shook his head, "No! I..No.."
"Then this is fine, right?"
Before Allen could protest, he'd spotted Kanda somewhere off in the distance, giving Allen the perfect excuse to run away.
The second time, was in the library.
Allen was checking out books for his next mission, content with reading silently in the safety of the large room, when a sudden warm feeling shook his body.
Two arms were wrapped around his waist, pulling him closer to the rosette, whom of which he'd somehow forgotten, was a bookman.
"Lavi!", he protested in a hushed tone, "Stop it! I told you, no!"
"Come on Allen.", he whispered softly, "Just give it up already. I told you, I'm the only one who's going to see anything.."
"I-I never agreed to that, Lavi!"
"I don't care.", he shrugged as he bit his neck, leaving a visible mark.
The third time, was possibly the worst.
It wasn't so much Lavi's fault, per say..
That entire day had just been completely filled with misconceptions, on both ends.
Early morning had approached and Lavi decided to pay his beansprout a visit, only to find the boy half naked in his room, with the door unlocked. His clothes were scattered unevenly around the room, and the boy's lower half was completely covered in blankets.
What if someone were to walk in? Had he not been listening when Lavi had said "No one but me"?
So, Allen awoke to Lavi hungrily engulfing his length, until the boy began to moan and thrust his lower half in his sleep, only truly awaking when he climaxed.
Lavi was towering over him, licking his lips, "Thanks for the meal, Allen."
To make maters worse, Allen had accidentally walked in on Lavi, in the shower. How it was possible? He didn't know. He'd always made sure to hit the bathhouse when he was certain no one else was awake..
The only obvious explanation: It was Lavi's fault.
In reality, Lavi had simply forgotten to take a shower that day and he'd yet to cleanse himself from the mission..or at least, a certain part of it.
Allen was having the same problem, the wetness between his legs hindering all conscious thought, making sleep very difficult, so he merely wanted to take a bath as well.
Lavi took the opportunity to attack the boy, ravishing every visible area of skin, (there was many, considering he was clad in nothing but a towel) and greedily sucking both pert nipples, paying extra attention to the sensitive buds.
Allen kept moaning against his own will, which seemed to encourage Lavi.
"Allen..", Lavi moaned against the skin, "Your body is so beautiful."
He blushed, fighting Lavi's grip.
Lavi didn't like that.
Though, after a while, Lavi had managed to overpower Allen, taking him on the bathroom floor in three different positions, rendering Allen's legs almost entirely useless.
The next day, Lavi was very displeased to have learned that Allen had gone into town with Lenalee, before Lavi woke up. He'd received word from Kanda, who stated "Moyashi and Lenalee are probably on a date or something. I don't give a damn what they do."
... Well, Kanda may not, but Lavi did.
And he spent that evening contemplating, thinking of every possible way to absolutely torture Allen.
It happened later that night. Everyone had gone to bed and Allen was exhausted.
Tiredly, he hobbled off into his room, shutting the door.
The door had clicked behind him, startling him as he rushed around to find none other than an angry, emerald eye glaring back at him.
At least he had sense enough to back away.
"Allen, I'm very angry with you.", growled Lavi, "Do you know why?"
Allen shook his head.
"Of course you don't.", he rolled his eyes as he took a step forward, "But I do. I'm just gonna get right to the point-What were you doing with Lenalee?"
"I..", he bit back a yawn, "We were just-"
"Just what?"
"S-Shopping! I..I'm sorry, Lavi.."
"You're not getting off that easily! From now on, you're not allowed to leave with anyone else-Not without my permission, got it?"
Allen shook his head, before tumbling over onto the small bed.
Lavi paid no heed, merely rolling the boy on his back, revealing his already heavily flushed face.
Angrily, Lavi unzipped his pants. He kneaded the soft fabric, earning a series of delicate moans before he pulled both restraints down below the boys ankles.
"L-Lavi..", he moaned, "I..'m sorry.."
"Yeah.", he huffed, "You should be, but I'm not done."
Without warning, Lavi attached what looked like a ring to the boys already heated cock.
He grabbed Allen by his hair, whispering menacingly, "On your knees."
Allen obeyed, breathless. He lowered himself to the ground, on both knees. Not long after, he felt something hard brushing against his lips, forcing them open. He took Lavi's length into his mouth, obediently sucking whilst two stern hands fisted his hair.
"That's it..", moaned Lavi, "Good boy, Allen."
It wasn't until he was close to climax, that he'd begun to lose control. Not only was Allen sucking at a rather slow pace, but he'd yet to use his tongue.
So, Lavi began fucking his mouth, reaching his climax.
The hot liquid shocked Allen, who opened his mouth to gasp-
Lavi wouldn't have that. He clamped a hand over Allen's mouth, forcing him to swallow.
"L-Lavi..", moaned Allen, "I.."
"You're not allowed to call me Lavi anymore tonight.", he warned, "Just master. Got it?"
Allen nodded, "W..Where do you want me..Master?"
Needless to say, Lavi was a little surprised. Was that all it took to get Allen to submit? Was it really that easy?
...Then again, he was tired. He probably thought this was a dream of sorts..
"On the bed.", he commanded, "Bend over and spread your legs."
He did exactly as told, bending over and spreading himself until it was impossible to do so many further.
Lavi attacked his entrance with two fingers, leading up to three, thrusting in and out of the boy's hole until he was certain Allen was ready.
"I'm going in."
Allen moaned, "N..No.."
Despite his protest, Lavi eased himself inside.
"D-Damn..", he groaned, "You're s-still tight."
Lavi began a slow pace, thrusting gently in and out of Allen until he heard the faintest of moans, and increased speed. It was then he practically ravished the boys hole, leaving Allen with nothing to do but grab on to the sheets as he was fucked senselessly into the mattress.
"I'm gonna cum inside."
"P-Please, no! I..I don't want..", he trailed off lazily.
Without another warning, Lavi held onto Allen's perfectly delicious hips, releasing himself inside. The seed then proceeded to seep out of Allen's hole.
With no strength left in his legs at all, Allen collapsed.
"Allen, get up off the floor.", purred Lavi, "You're making a mess. I'll have to punish you for that."
Moaning, he pleaded against it, before pointing to his own cock.
"What? The ring?"
Allen nodded.
"You want it off?", he smirked, "Convince me."
His mind wandered off into space as he searched far and wide for an answer. The only one being-
"L-Lavi..", he moaned rather loudly, before quieting down, "I..I'll be yours and only yours. You can use me whenever you want to. I..If you ask me, I..I'll suck you off. You can fuck my mouth and t-then leave me a slutty mess..I-I just want your cock penetrating my tight little ass, Lavi, please!"
. . . That was all Lavi needed to release the ring, allowing Allen to come all over himself, Lavi, and the floor.
It was then and only then, that both boys passed out.
After a while, they'd developed a regular..less, spontaneous routine. Every week, possibly at the end, after a bit of hard work, or after a long mission, one would run to the others room and request a bit of..stress relief. Meaning, Lavi would either fuck Allen senseless, or Allen would beg Lavi to fuck him senseless. Either way, Allen had stopped fighting back, and after a while, he wasn't sure why he ever had in the first place.
He definitely had feelings for Lavi..albeit, it took a while longer than either would have liked to realize those feelings, but they were present.
And, though Lavi seemed to have an eye (or, his only eye) on Allen's ass, it appeared that he was able to see through the lust somehow..he just didn't quite know how to show it. As was expected, for an emotionally detached bookman.
...However.
"No way in hell you're going on a mission alone with Kanda!"
"Lavi! This is important!"
..It seemed that Lavi's possessive attitude still needed a bit of adjustment, after all.
