Summary: Shizuo attention is caught when he sees Izaya wearing the unexpected.


Determination could work wonders.

It was something Shizuo had learned after chasing the flea one day, and actually catching him.

The flea, like always, had come to Ikebukuro even after he warned him to never step a foot close to where he lived, and proceeded to annoy him with his presence.

"Izaya! Fucking flea didn't I tell you never to step foot in Ikebukuro!" he said, crossing the street where he spotted the brunette.

The smaller male turned to him, an amused smirk gracing that annoying face of his.

"Well Shizu-chan~ last time I checked you were not the owner of Ikebukuro. So~ technically I'm allowed to be here," Shizuo eye twitched each time the brunette would drawl out a word, practically singing it.

"Shut up flea!" he answered, already tired of this talking. He ran as the brunette began to run as well, the crazy laughter of the other angering him even more.

"So slow today Shizu-chan~ whats wrong? Brain not working more than usual?" Izaya mocked with a chuckle , avoiding every object he threw his way with ease. The flea jumped around, maneuvering through people and alley ways, causing each object he threw to smash against another object or wall (luckily once people heard his roar and Izaya's remarks, they quickly scurried away).

Eventually their chase lead them to an alley way that was blocked off by a wired fence. Feeling victorious Shizui bragged.

"I'm going to get you now, you annoying pest!"

Even so the brunette only laughed louder as he easily used the garbage bin to jump to the other side. Once on the other side the brunette turned to him once more, annoying smirk still present in his face, as he blew him a farewell kiss and said goodbye.

Shizui had stopped in his tracks the moment the brunette jumped to the other side, not because he was surprised or even impressed with other male's parkour skill, but because of the glimpse he saw of what Izaya was wearing underneath his clothing. As the brunette descended to land on the ground, his shirt, along with his jacket, fluttered up as the wind caught it and his pants slipped slightly down as gravity took its part.

In that moment he had caught the sight of something he could only describe as being... Lacy? Watching as the brunette ran away, questions began to pop into Shizuo head.

Could it be that the flea is wearing lacy underwear?

Do they even make lacy underwear for men? Or could it be that the flea is wearing women's underwear?

The last question stayed in Shizuo mind, curiosity increasing the longer it stayed. He shook his head, doing his best to forget what he just saw and the question that would not leave his mind, as he turned to walk away. But not matter what his feet would not move to go the other way, his curiosity kept telling him to go after the flea and figure out if what he saw was women's underwear.

Knowing that once he had something in his head, his mind would persist until he gave into his curiosity, he decided to go after the brunette. He jumped over the fence and walked in the direction the flea had run to.

His determination to find out the truth seemed to make his senses of smell more keen. Following the stench, he usually found disgusting, but for some reason smelled appealing at the moment, he made it to Russia Sushi. He walked closer to the building, watching from the window how the brunette happily thanked Simon for the food and turned to leave.

Moving away from the window before Izaya could see him, he went to hide in an alley way he knew the other male he would pass. Waiting patiently, he heard the unmistakable steps of the flea as he got closer to where he was.

As soon as the brunette passed by him, Shizuo grabbed a hold of him and heard him squeak in surprise. Slamming him against the wall, causing the male to drop his bag of food, he pinned the brunette hands above his head and Izaya briefly looked surprised at being caught.

After his shock of being caught faded, the brunette playfully pouted.

"Neh~ Shizu-chan you owe me some more Ootoro," the brunette said as he sadly looked at the food laying on the floor, then looked at him with a smirk and mischievous eyes.

"Shizu-chan finally caught me! What now Shizu-chan? Are you going to kill me? Such a mons-"

"Shut up," he interrupted the brunette firmly. Looking down at the smaller man's pants, Shizuo began to feel excitement course his body. He noticed that the position he had Izaya in, caused for his shirt to rise enough to show some skin and his pants were slight lowered, confirming his suspicion.

Yes, Izaya Orihara was wearing women's lacy underwear, and in that moment Shizuo felt transfixed at the black lace teasingly peeking out from the pants. The hand not holding the other male's wrists, moved to touch the delicate material with his fingers. Izaya tensed, probably at the realization that Shizuo found out his secret.

Looking back at the now quiet brunettes face, he saw that Izaya's eyes were tightly shut closed and a blush was increasingly spreading from his cheek, to the bridge of his nose, to his other cheek.

Enjoying the reaction, Shizuo face moved to where Izaya right ear was and whispered:

"What's this flea? Do you enjoy wearing women's underwear?"

Izaya blush turned brighter. He watched as the brunette shivered when his thumb swiped back and forth, feeling both the softness of the brunette's skin and the slightly more rough material of the underwear.

"S-Shizu-"

"Take your pants off," he ordered, voice rough and low.

"W-what?" the brunette answered, not believing his ears. Shizuo grabbed one of the other male's hands, moving it to his pants to show he was serious.

"Take them off."

Izaya looked at him in shock, embarrassment already gone, and after a while his infuriating smirk was back.

"Oh Shizuo so kinky~" the brunette chuckled, undoing his belt, button, and zipper with one hand (Shizuo was still holding the other over his head). With a sly look, Izaya shimmied his waist, causing his pants to slowly dip further and further down. Shizuo just watched as more of the underwear was revealed inch by inch.

Lips becoming dry, he licked his lips in anticipation and was glad when the brunette was able to drop his pants fully with a snap of his waist.

The lacy underwear fit Izaya like a glove, fitting him like a second skin and driving Shizuo crazy. He never knew men could look so sexy while wearing women's underwear. Each contour of Izaya private parts were slightly covered by a skimpy black lacy, almost see-though, material that barely hid the brunettes now growing erection.

Needing to see more, Shizuo roughly turned Izaya around, and groaned in appreciation of the wonderful sight. Like the front, the material clung to the brunettes back side and barely covered the globe of each butt cheek.

He was brought back to his senses when Izaya let out a whine, lifting his gaze to the brunette face he saw the other male looking back at him heatedly. Izaya hands were flat on the dirty ally wall, while he looked back at Shizuo with a blush gracing his face and breathe labored even though things were only starting.

Grabbing a hold of the smaller male's hips, he grounded his clothed erection against the lacy covered ass and Izaya let out a moan. One hand kept caressing one butt cheek and the other moved to the front to rub Izaya's erection. The hands on the wall became into fists as Shizuo hand kept rubbing Izaya's clothed erection. The material became damp with Izaya's pre-come, turning Shizuo on even more.

"Shizuo" the brunette moaned, as his legs began to shake from the pleasure Shizuo was giving him. Each stoke of his hand would spread the dampness that soaked the underwear, and Shizuo could tell that Izaya was getting close to coming.

Not wanting it to end, especially since he wasn't close to coming, he stopped the hand rubbing Izaya's erection and smirked when the brunette protested.

Draping himself over the brunette's back, he blew into the smaller man's ear before whispering:

"Don't worry Izaya I'll let you finish soon enough, but with something much more stimulating"

Izaya shivered in eagerness and bucked his ass back. Moving away from Izaya, Shizuo unzipped his pants, a sigh escaping his lips when the uncomfortable pressure of his pants was released. Once again Shizuo grabbed a hold of Izaya's hips, and rubbed his now exposed erection, against the crevice of the lacy covered ass.

He moaned as the material made sparks of pleasure run through him and it became damp with his own pre-come.

"Shizuo more!" Izaya pleaded, not enjoying that Shizuo was the only one getting off now. Taking pity on the smaller male, he reached over to present Izaya with three fingers and soon enough the other male was coating his fingers with as much saliva as possible.

It wasn't the best choice, but seeing as neither had lube this was the fastest solution. Izaya tongue swirled around each finger as his saliva messily coated the fingers, his own chin, and some of his hand. After deciding that enough was enough, Shizuo pulled his fingers away, and with the hand not full of saliva, he pulled one of Izaya butt cheeks apart and hooked a finger into the underwear to move it away from covering his opening.

Inserting a saliva coated finger inside the twitching hole, he wiggled it around before inserting another. The brunette grunted in pain, but soon was thrusting his hips back into Shizuo hand. Once the last finger was inserted, Shizuo was sure he would explode if he did not enter Izaya soon.

The sight was completely lewd, the smaller male was moaning and moving his hips that where still covered by women's underwear, and instead of being repulsed, Shizuo was turned on more than he ever had been before.

Deciding that Izaya was stretched enough, he pulled out his fingers and quickly lined his erection against the brunettes puckered hole. With one swift thrust to the hips, Shizuo was buried inside Izaya. Izaya bit his arm to muffle the pained scream of being entered roughly. Not wanting to cause more pain, Shizuo stayed still, trying to ignore the incredible feeling of Izaya inner muscles contracting around him, wanting nothing more than to begin thrusting.

To distract himself, and Izaya from the pain, he began to rub the smaller male's covered erection. The lacy material, becoming more wet with pre-come, caused each rub to distract Izaya from the pain and soon enough the brunette was telling Shizuo to move.

Doing what the brunette asked, Shizuo pulled out almost all the way out, before thrusting roughly back in. Izaya threw his head back with moan and his ass pushed back against Shizuo hips. Tension running high, they began a rough and fast pace, each groaning and moaning in pleasure.

While thrusting, Shizuo kept teasing Izaya by pulling the already skin-tight lacy underwear and rubbing his erection, knowing that Izaya wanted skin to skin contact. The other male would try to get the hand rubbing his clothed erection, to move inside the underwear and rub him, but Shizuo wouldn't do it. He wanted Izaya to soil his underwear with his come, something about that turned Shizuo on.

Izaya legs bucked when Shizuo hit his prostate roughly, face now pressed against the wall as their bodies became closer and thrusting became more frantic. If it wasn't for his hands holding Izaya hips, he was sure the other male would have collapsed because of his weak knees. Proud of himself for making Izaya knees weak, he continued thrusting purposely trying to hit the smaller male's prostate every now or then.

As they got closer to their release, Shizuo had Izaya body sandwiched between him and the wall, their thrusts becoming erratic and fast. His fingers probably leaving bruises on Izaya hips from grabbing too hard, and one of Izaya hands was bleeding since the brunette was biting it so hard to avoid moaning to loudly; seeing as people were passing by.

With one hard thrust to Izaya's prostate, the smaller male tensed and shuddered intensely as he came in his underwear, while Shizuo thrust two more times before coming inside Izaya with a loud grunt.

Pulling out of Izaya, he watched, as he zipped up his pants, how the brunette sagged to the dirty floor of the ally way and was proud to notice that the lacy underwear was soiled by his and the other male's seed.

"Shizu-chan~ I can't get up!" the other male whined, his arms extending as a signal for help. Looking at the brunette, then around, he decided to help the annoying flea. He picked up the smaller male and pulled his pants back on, ignoring the brunette's protest of his underwear feeling "icky" and slung him over his shoulder.

The annoying flea kept protesting as they walked, and Shizuo smirked, knowing that Izaya didn't even know that the only reason he was helping him was because their little fun wasn't over.

He wasn't going to let Izaya rest today.
