Chapter Text
It was quite possible Magnus was developing an innocence kink.
Alexander was innocent. Magnus already knew this, he’d been the boys first kiss after all. But moments like this when their bodies were pressed together and their lips locked in passion it was beyond obvious that Alec was innocent.
He always let Magnus lead, shyly tilting his head to meet the Warlocks, only to pull away a second later not knowing what to do next. The way he bit his lip and looked up from underneath his lashes in the most adorable and heart-stoppingly beautiful way. The little pants he let slip the few times Magnus had managed to coax the angel in a make-out session rather than a chased kiss. The pretty pink he’d flush when he got hard or let out moan. God Alec’s moans were the sexiest things Magnus had ever heard. All of Alexander was sexy.
What their doing now is new. They're lying down on the coach, Alec on the bottom with Magnus on top. Alec never let him get in this position, they’d always been sitting before, side by side whereas now Alec was at his mercy. The position gave Magnus a perfect view of others long neck and damn Magnus wanted to bite it, leave it covered in marks so everyone knew who the hazel-eyed beauty belonged too. But he held back instead choosing to lightly kiss the exposed skin. Alec shuddered beneath him. Feeling bold, Magnus gently ground their crotches together and Alec practically whined at the friction. Spurred on Magnus did again and again until Alec was a whining mess.
“Mag-nus, ohh God, I-I feels so Good” his voice was high and breathless and Magnus loved it, he wanted to hear that voice more.
“Oh Alexander” he purred hotly “your so beautiful, so good for me” Magnus whispered in his ear. The boy shivered again.
“Ple-ease Magnus-s more, More” Alec begged and Magnus pulled back to look at the Shadowhunter. By Lilith, he was a sight. Lips kiss swollen, mouth agape, face flushed and doe eyes wide and dazed. Alexander Lightwood was art.
“You want more Alexander, are you sure?” Alec nodded his head rapidly and Magnus smirked down at him. He would ruin this boy in the sweetest way.
He kissed him again and let his fingers wander south. Strong hands lightly gripped long Bambi like legs and pulled them up and apart allowing Magnus to rest comfortably between them. Then he started to thrust again, harder this time and faster. The layers fabric doing little to stop pleasure. He attacked Alec neck next, this time sucking on it and nipping at soft flesh. The tough battle-ready warrior beneath him falling apart at his careful admissions. His body like putty in the Warlocks hands, a melody of “please”, “Oh god” and “Magnus” falling from the boy's lips.
Magnus wasn’t unaffected either, his dick obviously hard in his pants and he was letting out his own groans. They’d have to stop soon, they couldn’t rush this but Magnus could let it go on a little longer. Alexander slowly slipped his hand under the hem Magnus loose silk shirt before pausing.
“-can I-I?” Alec finishes his question by pulling desperately at the garment.
“Oh darling, you never have to ask”
Alec slowly dragged his hands up Magnus body and it felt like heaven. This here was Magnus’s personal heaven. Calloused fingers drew patterns on softer unblemished skin. Magnus followed suit letting his hands rack through Alec’s chest hair and play with his nipples making him arch off the couch.
“Can I take it off?” Magnus asked lowly eager to see his Shadowhunter now that he had permission to look. Except he didn’t. Alexander immediately clamped up, hands falling from Magnus’s body to clutch at his chest. It was amazing how fast someone’s body language could change.
“Wait, I don’t want, I didn’t mean, not ready” Magnus pulled back and hushed the younger man not wanting him to work himself up.
“I wasn’t asking for more, just your shirt off but if you don’t want to that’s fine. We can stop here” Magnus explained, mentally slapping himself for getting too excited. Alec was breathing heavily, his eyes shining with uncertainty. Magnus figures Alec wasn’t quite ready for talking yet.
“Would you like to continue where we left off or do you want to stop completely” Alec still looked unsure. His eyes were watching Magnus, their bodies pushed together, his hands, the floor, everywhere.
“Alexander use your words. There's nothing embarrassing about what we were doing or not wanting to do something” Magnus pushed a bit more. They couldn’t move forward unless Alec told him what was going on in that gorgeous head of his.
“It’s ruined now, I was doing so well” Magnus raised his eyebrow.
“First, nothings ruined” Magnus gave a quick shallow thrust that made Alec squeak. Their dicks obviously still hard
“Second, and more importantly, were you just going along with that because you thought you should. Were you forcing yourself to do that?” Alec looked up shocked.
“What No!!! Magnus, I was definitely enjoying it!! I-it’s just-i wasn’t thinking.” Magnus stayed quiet letting Alec talk.
“I-normally when we do things like this, I get in my head and I freak myself out. This time I was relaxed, it wasn’t getting to me. It was good and then...”
“And then I tried to take your shirt off and triggered you. I’m so sorry Alexander”
“Don’t apologize, it’s not like you ripped my shirt off without asking” no I didn't but I definitely thought it, a voice in Magnus' head whispered.
“You didn’t answer my question, keep going or not”
Alec smiled sheepishly “not” Magnus smiled and quickly pecked his Shadowhunter on lips “ok”.
“But could we talk about it,” Alec asked hopefully. He had a youthfulness about him that totally contradicted what he was asking for.
“Talk about what Alexander” Alec blushed
“You know what” he really did sound like a child and Magnus couldn’t help but tease him.
“No Alexander, I’m quite sure I’ve got no idea what you want to talk about. Could you be a bit more...detailed” Magnus said with a shit-eating grin. Alec more like he was in pain.
“About sex, there I said it” the warlock felt angry, not at Alec but at the people that conditioned Alec’s into thinking sex and even saying the word was a bad thing.
“Yes well-done darling, but what do you want to know exactly?” The blushing Shadowhunter looked down again clearly embarrassed. They were sitting next to each other now.
“Just, I don’t know. I feel like I freak out because I don’t know what to do. So I thought that if I know the theory behind sex and other sexual things then maybe I wouldn’t be so unsure” The sweet boy was breathing heavily by the time he’d finished and was redder than Magnus had ever seen him. Honestly only Alec could talk about “the theory of sex” and sound both endearing and hot.
He smiled at the Nephilim, “ok then darling, you want me to give you the sex 411”
“Yea—eah”
He was going to have so much fun teaching this innocent man, he couldn’t wait to see the confidence grow inside Alexander as he got more comfortable with himself.
“Let class begin”
