Chapter Text
Magnus and Alec didn't do much in bed. Not because they were boring, or they didn't like each other intimately, but because Alec was new to everything. He could be a badass shadowhunter but it didn't mean he was absolutely confident when he was naked with Magnus. In fact Alec was a shy, and very inexperienced, and Magnus loved making his boy flush red all over while kissing him, praising him, touching him on all the sensitive spots he knew. No matter how many times Magnus told him he loved him the way he is, assured him that sex wasn't the most important thing, Alec knew that Magnus wanted more. He has seen the way Magnus watched porn (oh yes, every now and then they watched porn together) he has seen how Magnus' eyes sparkle at certain sexual acts. And Alec wanted to make Magnus' eyes sparkle because of him.
The young boy was just sitting in bed, waiting for his boyfriend to finally join. Magnus came out of the shower with a towel around his hips, approaching the bed with a smile. Alec knelt on the bed, came closer to the edge, slid palms up Magnus' sides and met his lips for a soft wet kiss with a hint of hunger, promise for something more tonight. Magnus' slid hands up his biceps, tilted head slightly and sucked at Alec's upper lip.
'Hey.' Alec mumbled when they parted and looked Magnus in the eyes with growing with lust eyes.
'Hey.' Magnus smirked and rubbed thumbs in Alec's muscles. 'Playful tonight?'
Alec bit his lip and nodded slowly, he lowered down and sat on his legs, curling fingers in the Magnus' towel, looking up at him with innocent look, so pure, nervous, but excited. Magnus' brain started catching up pretty fast, his cock slowly rising to attention. The look on Alec's face made the warlock feel superior, excited, so turned on like he hasn't felt in days.
'Can i ?' Alec asked quietly, hand resting on Magnus' thigh.
'Are you sure?' Magnus caressed his cheek with a thumb.
'I'm sure i want to try.' Alec whispered in response, tilting chin up just slightly against Magnus' touch.
'Take your time.' Magnus answered with a smile, just standing on the side and touching Alec's skin in comfort, encouragement.
Alec took a breath, slowly unfolded Magnus' towel and let it drop in his feet, he barely held a gasp by the sight of Magnus' thickening length, he usually didn't stare like that, they were face to face when Magnus' cock was anywhere near his body.
'It's okay... relax, take your time.' Magnus whispered and glided fingertips along Alec's neck, shoulder, down his arm and back up, he flicked wrist and the lights went down slowly, a blue one falling on them from the TV.
Alec placed a soft kiss in the middle of Magnus' chest, he planted one farther down, and continued slowly like that, using the foreplay to wrap fingers around Magnus' cock and stimulate him with steady strokes. He bent down little more, warm breath ghosting over the head. Magnus held his breath and finally released it heavily when Alec closed his eyes and wrapped lips around the smooth tip. He lowered down a little more till the head was in his mouth and shyly, hesitant pressed his tongue against the slit, feeling up the form and shape of the head with careful swirls of his tongue. He heard Magnus take a breath and felt so proud of himself.
Alec pulled off from the head and slowly took it back in his mouth, sliding down the length a bit farther, he wanted to have that taste, and he was sure Magnus wanted it in a while too. He repeated it a couple of times, using his wet hot tongue to take a feel of Magnus' member and the warlock's knees were going weak already. He didn't want to admit to Alec that he wanted the boy to please him with his mouth, to try to learn, but Magnus wasn't the type to force anything onto his partners. And especially not on Alec.
'Suck a little, honey.' Magnus guided him quietly, hand gentle on his cheek.
Alec tried to create a pattern of lowering down and sucking on the way up. He knew he was doing right when Magnus moaned and buried fingers in Alec's hair, encouraging him to keep going.
'Very good, keep going, Alexander, feels so good, love.' Magnus' praises made Alec braver and turned him on so badly, made him hard in his underwear, flushed all over with pride and maybe a bit of shame to have Magnus' manhood in his mouth. It was dirty like nothing they have done.
Alec moaned around his length and tried to take Magnus even deeper, his warm hand stroking the base, he heard Magnus' breathing getting heavier and his hips stuttering against Alec's face but he was restraining from fucking his mouth. Alec was too inexperienced to handle that just yet. Magnus roamed fingers in his hair and after some time gripped at it as the tension in his gut was about to explode.
'Alexander, i'm close, feels so good.' He moaned and his breath stuttered as the orgasm hit him. Alec pulled off of his cock just on time and felt Magnus' come dripping down his chin and chest, he was too flustered to look at him in that moment, just listened to him moan and play with his hair.
Magnus pressed fingers under Alec's chin and made him look up. Alec met Magnus lust blown eyes and parted lips, something predatory in his look. 'Such a good boy, Alexander.' He praised again, wiped the come from Alec's chin with his thumb and slowly pressed it into his mouth. Alec took a deep breath from surprise and wrapped fingers around Magnus' wrist, arching back as he tried to avoid that, however he circled tongue around Magnus' finger, tasting the salty warm release of his boyfriend. He didn't know how to feel about it, it wasn't the most pleasant thing he tasted, but it wasn't that bad either, there was something hot about Magnus making him taste him like that. Alec had been nervous about doing such thing entirely but Magnus was so good with him. He moaned shortly around his finger until Magnus pulled it away and leaned to kiss him. He straddled Alec's lap and slowly pushed him to lie down on the bed.
'I can't miss to thank you for that.'
'You don't have to.' Alec couldn't believe how quiet his voice came.
'I know, i just really want to.'
The blowjob Alec received couldn't compare to anything he ever felt before. Magnus reduced him to heated melting mess and he was sure he will be incredibly horny for the entire week.
