Magnus' one hand immediately was on the small of Alec's back, pressing their bodies together tightly, while his other hand landed on his ass, gripping so hardly Alec feared his shorts might tear. Not wasting any second, Magnus dove in for a kiss, stealing his breath with the heated acuteness and, in a more practical way, with the tongue attacking his mouth. He moaned loudly when suddenly Magnus' hand slid under his shorts, stroking the tender skin and sharply manicured nails digging into his flesh, leaving him helpless to the plundering of his lips and mouth and saliva already trickling down the side of his chin.

Hungrily eating up every sound, every twitch and jerk Alec made, Magnus could feel his self-control vanishing into thin air and he found he couldn't really care. He wanted to lose control, make his angel scream and cry and beg until he had every precious place of Alec marked as his. Their mouths had become a mess, saliva from both of them smeared around them, tongues meeting in between just for Magnus to dip his back into Alec's sweet mouth until his young lover could do nothing else but take it.

His own hands which were clutching Magnus' shoulders slid under the red shirt he wore, greedily touching the soft, scar free skin and slender muscles until Magnus finally broke their kiss for just a short moment, letting Alec take it off. His blue eyes focused when they could finally take in his lover's glitter sprinkled upper body, his hands sliding from Magnus' neck down his collarbone and chest to his taut stomach. Feeling Alec's gaze and strong hands on him, Magnus couldn't help but grab his lover by the hips and push his own upwards, earning a surprised moan. "Magnus!" Continuing his pushing and pulling, he asked, "What is it, biscuit?"

Alec's face was dipped in scarlet, eyebrows furrowed tightly and his mouth hung open invitingly.

His hands formed fists on Magnus' chest and he let out a low whine, needy and unguarded, as if that would answer Magnus.

Suddenly Alec's shorts were gone, snapped away impatiently, and a literally magically lubed finger began probing at his entrance. Magnus straightened his back, not leaning on the back of the couch anymore; his grip was tight, jolting Alec's body towards his own.

"Really, you didn't actually think you could just show up and give me a lapdance, a lapdance Alexander," he snarled and pressed his finger stronger against Alec, "and I wouldn't fuck you, did you?"

He pushed his index finger inside, almost all the way, relishing in the loud groan Alec let out.

"Tell me, angel, did Isabelle persuade you into this?" Magus asked teasingly, pumping his long finger in and out.

"N-No—ah! Wasn't Izzy," was all Alec replied, not wanting to admit it had been his idea, his little obsession since the party.

"No?" Magnus asked, voice colored in obvious arousal but also surprise. "Then who? I really want to know who I have to thank for this." He smirked up into Alec's face which was a few inches above his own. Alec arched his back when Magnus pushed in a second finger, moving them deep inside the Shadowhunter before promptly taking them almost all the way out. He knew Magnus would tease him until he told him, wouldn't fuck him with his fingers like Alec wanted him to.

"It was m-my idea, just mine," he told him between gasps. "You said it at your last party—uah!—and I couldn't stop thinking about it. That I wanted to give you a l-lapdance." He finished with a shuddering breath; Magnus' fingers had stopped moving, the warlock stunned into silence. Alec looked down, worried that might have been the wrong thing to say, only to let out a hoarse cry when Magnus added a third finger and shoved them deep inside him.

"You little... You have no idea what I want to do to you right about now. How perfect you are, how very perfect." Relentlessly moving his fingers in and out, Magnus found a perked nipple with his mouth and lightly bit down before circling his tongue around it.

Alec tugged harshly on Magnus' soft hair while his body was being ravished both from his bottom and chest. His cock smeared pre-cum all over his lover's shirt and the black leather pants were probably a mess, too.

When Alec started to adjust the movement of his hips to the pumping of Magnus' fingers, he pulled them out after one last deep push and sat back.

Alec's mind was cloudy and unfocused with arousal and he looked at Magnus, knowing the preparations were over.

"Come here." He whispered and pulled Alec down.

With a snap of Magnus' fingers Alec could hear his pants being opened. Leaning up, using his height to his full advantage, Magnus kissed him hard. While pressing their tongues together and messily meeting the other's mouth, Magnus tucked out his own cock, relieving himself from the pressure of his tight pants.

His hands slid down his waist to grip his hips and he pulled Alec onto him. He felt the head opening him for Magnus, a delighted and breathless moan escaping him at finally feeling his lover inside him.

Magnus pulled him down eagerly and when Alec was sitting fully on his lap, he licked Alec's neck from base to chin. Alec let his head fall back, the sensation of Magnus' tongue hot on his skin and causing him to moan loudly. He felt Magnus opening him up, the first stretch always the most painful and most exquisite.

Without a word of warning, Magnus began moving his hips, slamming himself deep inside Alec's body. His hands were spreading Alec open, his cock sliding in and out relentlessly, his face buried in his neck while his lover clung to his shoulders helplessly.

"You feel so good, Alec, so good you have no idea. Don't think I will let this end quickly, no way," Magnus told him while mouthing his ear, more licking than kissing, sending shivers all over Alec's skin. Alec tugged Magnus' hair then; he couldn't stand the hot kisses along his neck and ear any longer, not when his lover was burying himself inside him again and again at the same time, not giving Alec any break. He felt as if he was running; running after Magnus and already out of breath, panting desperately to fill his lungs with air but to no avail, Magnus still ahead of him and setting the pace. He could do nothing but cry out his pleasure while Magnus snapped him up and down his cock, his body melting away.

"Magnus!" he whined, panting hard, "I can't—can't like this, plea—" interrupted by Magnus pushing deep inside him, he moaned loudly. "N-no! Don't—not like this, no!" Alec was crying out, his mind too dazed to know what he wanted. To Magnus stop fucking him like this because he wasn't used to feeling dizzy from pleasure like this; or did he want to be taken like this more, until all the dizziness made him black out.

While his own mind wasn't able to decide, Alec still sobbing out no's and pleading Magnus for whatever it was he wanted, the warlock decided for him.

"No? You don't like it like this, darling?" He whispered in Alec's ear before pulling back and locking their eyes. His eyes were black orbs, the color almost completely gone, but suddenly the black went back, just a slit amidst bright yellow and green now, like a cat on the hunt. Amusement flickered in his eyes and the luscious grin on his lips made Alec's mouth go dry. Giving into a sudden urge, he looked away to the side, the heat in Magnus' expression threatening to suck him in. "Ah-ah, I'm not letting you escape." Magnus' large and slender hand, adorned with rings, found Alec's cheek and he pushed his head towards him again before he pressed their lips together. The kiss was open-mouthed, their mouths wet and hot, Magnus kissing him tenderly the one second and drinking up all his lust-filled moans the next. Alec could still feel him deep inside, a constant stretch, hot and pulsing inside him.

Magnus pulled free from the kiss, just to let his mouth wander up and down from Alec's cheek back to the side of his mouth. "Then how about we try something else?" He suggested huskily, out of breath himself now, and before Alec had a chance to ask what he meant, he felt Magnus slide out of him.

"Wh-what—" he started, just to be pushed onto the length of the couch on his hands and knees. Magnus was standing at the head of the couch, a smug grin on his reddened lips, his eyes eating up the view of Alec in this position. Alec looked over his shoulder, bared and open to Magnus' eyes like this he felt the hotness of his arousal tighten in the pit of his stomach and he wanted Magnus back inside him, wanted Magnus to ravish him and have him. "Aren't you a good boy. First a lapdance and now you're practically- scratch that- you are offering that pretty ass of yours to me." Magnus smiled at that, a lopsided one, and he knew Magnus would mess him up, until he himself was nothing more than a mess of sex and raw lust. His hands slid up the inside of his thighs, spreading them to give Magnus better access, and a better view too, and came to a halt on Alec's ass. "Really, so pretty..." Magnus murmured almost just to himself, pulling Alec backwards towards himself and entering in a fluid motion.

Alec felt every inch spreading him open again, letting out a small shout when he felt Magnus' hips colliding with his ass, reaching deeper than before. A wave of heat crashed through his body so fast and powerful his vision blacked for a moment, his muscles tightening around Magnus right when he was pulling out.

"Greedy, are we. Don't worry sweetheart," Magnus commented, his lopsided grin still on his lips, "I'll fill you up with all my love."

Alec knew this was all the warning he would get, and he wished he could say he wasn't surprised when Magnus' next thrust pushed his body forward on the couch, but the loud scream he let out disagreed. He arched his back, the line of his body a breathtaking sight and Magnus let his eyes shamelessly take it in. This position wasn't the most favorite of Magnus; he liked to take Alec on his back, watch his exquisite face during the heights of pleasure, liked to trace his nipples or let his eyes fall between his legs, all which was impossible in this position. Still Magnus enjoyed the forcefulness he was able to give his thrusts like this, the view of Alec's scarred and marked back, beautiful and perfectly muscled, the tight set of his shoulder blades with his head of ink-black hair in the middle whenever Alec threw his head back in a cry of pleasure. He enjoyed to look down where they were connected, Magnus sliding in and out without pause and Alec letting him, his opening scarlet and wet; oh yes Magnus enjoyed that greatly.

"It's t-too deep, Magnus, you're—" again he was interrupted by a hard thrust, crying out while tears started to gather in his eyes. "So deep, Magnus, I can't!"

Alec was losing control of his body, drowning in the pleasure of having Magnus reaching deep inside his body, loving him, taking him to his liking. Tears started streaming down his cheeks and his arms gave out at being fucked so roughly.

He cried out Magnus' name loudly; he knew this new position would allow him to reach even deeper, he was almost amazed his mind could process that much in his current state, but all the knowledge of it didn't help him at all when he actually felt his body being spread open mercilessly.

"That's right my angel, cry out all your pleasure. All the pleasure I'm giving you."

Magnus knew he was being rough, that Alec wasn't used to it, but he wasn't able to slow down, wasn't able to gain his control back, not with Alec crying out with his lovely voice, not when his ass was sucking him back in impatiently every time, begging him to not stop. He leaned down and kissed up and down Alec's back, sucking and marking especially endearing spots; the spots which made Alec sob out and arch his back even more.

When he reached behind Alec's ear, one of his biggest weak spots, he bit down hard and was rewarded with Alec bucking into him, whining desperately. His face was pressed into the couch, saliva and tears forming a wet spot, his cheeks deep red and blue eyes unfocused and still most gorgeous. Magnus stood up straight again, putting one knee on the couch and using the other on the floor to push himself inside Alec, strong and heavy. He was nearing his climax but he still wanted to hear Alec some more.

He didn't disappoint in the slightest, the scream almost forming Magnus' name but his voice breaking, his body tightening around his cock so violently he only saw white for a few seconds.

"God, Alexander! I'm close, so close my angel, so close because of you."

"Pleasepleasepleaseplease Magnus—don't stop, don't!"

"I won't- I could not. You feel too good, Alec, so so delicious." His thrust had become jerking and erratic; a reply in its own. He wrapped his hand around Alec's cock, the two rings he still wore providing almost cruel friction while he pumped.

Alec threw his head back, his body shaking with the sudden force of his climax and he cried out while Magnus buried himself deep inside, his own climax taking hold of his body. Crying out Alec's name he let himself be taken over by the blinding and painful pleasure, filling Alec like he had promised.

He had one hand on the back of the couch, steadying himself while all the strength was fleeing his body. He felt Alec shaking underneath him, his breaths panting and the slightest sob accompanying them, his upper body moving in rhythm.

Alec knew he was a mess, just like he had known he would end up; his face was flushed and wet, his whole body drenched in sweat, his ass in something else entirely and he knew would be aching tomorrow. When Magnus leaned down to kiss the side of his face that was turned upwards and whispered "I love you," he knew it was more than worth it.

"I love you too. I wonder what your Christmas present will be." He grinned tiredly but chirpy, and Magnus' own grin was all the answer he needed.

Finally the promised second chapter!
I got around to finish it because today (yesterday by now) was my birthday. So, birthday present to myself and you!
I hope you enjoyed it and just shoot me a message if you see any mistakes.
