Alec let out a wanton moan as a burst of pleasure shot through him.

"Harder!" he keened, spreading his legs wider to allow for better access. The man above him complied all too eagerly, using his super-human strength to pound into the willing ass beneath him.

Alec screamed in ecstasy. The pain of anal sex without lube just adding to his masochist desires. His knees were bloody as they were dragged onto the cold, stone floor and his wrists were chafed as the cuffs dug further into them with every tug and pull.

His arousal was practically begging to be released from the horrid cock-ring.

"Ooh...ung! Ple-please Mast- Ah! Master! Ah! Hah!" The man only smirked, not that Alec could see, and delivered a heavy blow to his already stinging ass. He yelped and whimpered some more.

His Master stopped thrusting, much to Alec's chagrin, and whispered huskily in his ear. "You are such a slut, Alec. Following me and begging me to fuck you senseless." He rammed his hard-on, once, into the boy beneath him, causing him to let out a sinful moan. "You're a whore. A filthy cock-slut. Why should I allow you to come?"

Alec tried rocking onto the hard cock up his ass but strong, calloused hands stopped him. "Oh please Master! Don't stop! Oh please don't stop! Yes I'm a cock-slut and, oh, you have such a nice, big cock. Oh why did you stop? Am I not a good little slut, my Master?"

The Master chuckled darkly. "You are a good little slut. I wonder how you're parents would feel if they knew how much of a filthy whore you are. Or what about Jace and Izzy? The Clave? Or better yet... How would Magnus feel?"

Alec groaned in slight shame. He didn't even want to think about the consequences of anyone finding out, especially Magnus. It's not that Alec didn't want to be with Magnus, no that definitely wasn't it, it was just that Alec craved more.

Magnus is, and always will be, a gentle lover. He would always take his time, when it came to making love, slowly preparing him. Magnus treated him as if he were made of glass, despite the fact that he was a Shadowhunter. Every time he would bring it up, Magnus would tell him that he deserves to be treated like a precious jewel, for that was who he was to Magnus. Alec loved it, he did, but he also hated it. He wants Magnus to just let go and pound his ass into submission. He wants, no needs to be dominated and treated like a slut. Call him strange but he couldn't deny his fantasy.

How he ended up submitting to Sebastian is a whole other story. He doesn't even know how, exactly, it started. He had spotted him and chased after him, bent on getting his revenge. He caught up and they argued for a while, sometimes letting loose a few punches and kicks. Then they were kissing and Sebastian was practically radiating dominance and Alec found himself on his hands and knees screaming like a wanton whore as Sebastian pistoned in and out his hole at inhuman speeds.

They had told each other, and themselves, that it was just a one-time thing. An accident that was never meant to happen again. Yet they found themselves yearning for each other until, finally, Sebastian couldn't take it anymore and, throwing caution to the wind, he sent Alec a note saying when and where. The demon-Nephilim wasn't really expecting Alec to come and, if he had, he had thought he would have brought back up, but he didn't. This illegal rendezvous started about two months ago and they've been meeting twice or thrice a week ever since.

Alec knew that, so far, he had been lucky. He also knew that soon his luck would run out and he would be caught and probably stripped of his title and marks. He could probably even be executed for fraternizing with the enemy. The risk of getting caught was high, but that just made the meetings all the more tantalizing and addicting.

Alec pushed any thoughts of getting caught out of his head. He clenched his walls around the thick, pulsing member causing Sebastian to growl in surprise and lust.

"Just shut up and fuck me!" Alec growled right back, impatiently.

There was no movement for a while and Alec was afraid that Sebastian was going to stop and leave him. Sebastian leaned forward and unshackled Alec from the wall. Pulling out, he flipped Alec onto his back and unlatched the cock-ring.

Crystalline blue eyes widened as they met lusty black eyes framed with pale blonde lashes. Alec gasped as took in Sebastian's form. The light above them made it look as if he were a god. His short platinum blonde hair was illuminated giving it an ethereal look. Pale, muscular arms were on either side of his face and his flat, well-toned stomach glistened with sweat.

Sebastian drank in the angel underneath him. There was no way he wasn't an angel. His soft hair flayed out around his head giving him the allusion of a black halo. Beautiful, half-lidded blue eyes were filled with desire. Red, kiss-swollen lips were parted slightly and invitingly. His cheeks were aflame, giving him a look of innocence. Sebastian carefully sat back; balancing himself on his heels, and ran his hands over soft skin. Years of training didn't seem to harden his body, leaving him slim and smooth.

For a moment something flashed in their eyes but as quick as it came, it vanished. The moment vanished and animalistic lust flared up in its place. Sebastian grabbed Alec's face and roughly kissed him. Hands flew over the others body seeking out every nook and cranny.

Alec wrapped his legs around Sebastian's waist. The sudden weight change had Sebastian falling on his butt and Alec pushed him the rest of the way down so he was lying on his back.

He growled and tried to sit back up but Alec pushed him right back down.

Alec was feeling dangerous and experimental. Another thing Magnus would never let him do: Ride him. His ass was stinging from the assault from earlier and decided that as nice as it was fucking without lube, if he wanted to go through with this plan he was going to need little to no resistance.

There was no lube so he decided to go old school and he bent down and swallowed Sebastian's cock. Sebastian gasped and arched into the warm, wet mouth.

Alec swirled his tongue around the engorged member lazily, moaning every once in a while.

Sebastian was going crazy, any thoughts of regaining the upper hand flew out the window when Alec deep-throated him. No wonder Magnus stuck by the boy. With skills like this, he didn't want to have to let Alec go.

Feeling that Sebastian's cock was wet enough, Alec pulled back with an audible pop. He straddled Sebastian and, lining himself on his cock, he sat down quickly.

"Oh! Fuck!" Sebastian shouted.

Encouraged, and slightly smug, Alec set up a steady pace. For once, he felt in control and he found that he liked it very much. Deciding to experiment some he sat up so that only the head of Sebastian's dick was inside of him. He hovered over it and moved slightly so that it would only go in about an inch and no further.

He kept this up for a moment and, when he felt Sebastian tensing, he slammed down on the cock preventing Sebastian from thrusting into him.

He leaned backwards, so that he was in crab position, and continued pounding. It was an awkward position, but it allowed the perfect angle so that Alec's prostrate was being hit with every single thrust.

His arms grew tired so he sat up again. Pausing for a moment, he shifted slightly and pulled Sebastian up to kiss him.

He broke the kiss and gave a single demand.

"Fuck me Master."

He didn't need to be told twice. Grabbing a hold of Alec's hips, he bounced Alec on his cock with so much force that he went deeper and deeper with every thrust.

All Alec could do was moan Sebastian's name, scream and dig his nails into Sebastian's shoulder.

They quickly reached the point of no return. Alec came first, screaming Sebastian's name, his seed spraying all over their chests. The walls around Sebastian's member contracted deliciously and after two more thrusts he found himself shooting the biggest load he has ever had, painting Alec's insides a creamy color.

They collapsed on the floor, the chill of the stone cooling down their heated skin.

After a while Alec, slowly and painfully, got up. Wincing, he looked for his clothes.

Suddenly, he found himself in a pair of strong arms, facing a muscular chest.

"Put me down Sebastian." Alec deadpanned, staring intently at him.

"Now why would I do that?" Sebastian chuckled, then preceded to carry his prize towards the shower. "Besides we both need to get cleaned. Why not do so together?"

Alec futilely pushed against Sebastian's chest. "If we do so together, we will just end up having more sex!"

His captor smirked. "That would be the plan."

Reaching the shower, Sebastian turned it on and slammed Alec into the wall, suckling his neck.

Any attempts at resisting diminished and Alec found himself, once again, screaming Sebastian's name.

That was a very crappy ending... oh well. This here pairing has to be my favorite crack pairing. Don't know why, but it is. So this will be my third time writing smut and my first time writing a story for the TMI fandom.

This story was basically a "What if..." type of story. Now we all know that Sebastian killed Max and tried to kill Izzy and Jace. I always found it strange that he never really tried to kill Alec. So I thought it was because he had some unresolved feelings for our favorite blue-eyed Shadowhunter. Him telling Alec that being gay was wrong was just him trying to convince himself that he couldn't, wouldn't, and shouldn't love Alec.

This one shot, it self, takes place about two months after Malec honeymoon. I jumped on the Masochist!Sub!Alec boat like it was my lifeline and I have always had a thing for Sebalec so this happened. Malec is my religion but I will go down with the Sebalec ship!

Now can someone please give me a reason why there aren't a lot of Sebalec stories? And Raphael/Alec stories while we're at it?

That is all... or is it? ...
