“I’m a warlock,” Magnus says and while his tone isn’t bitter, there is a flat note to his voice that Alec aches to soothe away. “I can never sire children, Alexander.”
And Alec feels like he’s missing something again and he waits for a moment before continuing.
“I mean, I wasn’t really expecting us to sire children on each other.” Alec gives Magnus a heated look, “though you’ve certainly made an effort on my behalf.”
And Magnus relaxes, his expression going smug as he relaxes, arm going up around Alec’s shoulders as he tugs him close with a chuckle.
“I have, haven’t I?” Magnus teases, mouth brushing against his neck and Alec wills himself to stay on track.
“More like—“ and Alec coughs to distract them both, “I was thinking that over time, we might find ourselves in a situation, where taking in a shadowworld child is the better outcome. For the child and for the shadowworld.”

And Magnus has to laugh because Alexander looks less hopeful and more like this is an obvious eventual need.
And unfortunately, it’s unlikely that he’s wrong.
“I suppose we will need to figure out if we want that then. Is this going to set off your biological clock, darling? Should I commission and set aside a surrogacy fee? Should I prepare my heart for a little scowling cherub toddling about?” Magnus is only teasing at the beginning and he finds that his words grow more sincere at the idea of a baby Alexander.
It’s a sore spot, but his shadowhunter seems to easily bypass all the parts that have caused Magnus to feel inadequate in the past.
And Magnus is smiling softly but Alexander, his darling shadowhunter looks so offended that it’s confusing.
“Magnus, we can’t have children with lower life expectancies than you.” Alec says, like it’s obvious, “the lifespan of our children from only my own blood would hang over our heads. I could and would never ask such a cruel fate of you.” And Alec gives him a look like Magnus is the one being unreasonable.
“Even if my soul is tied with yours, there is no guarantee the child would have or want immortality.” And Alexander sighs reaching out to cup Magnus face. “I’m too selfish to risk sharing your heart with something I know will only cause you pain. I’d rather risk never sharing the joy raising a child with you than raise one that would break your heart.
Alexander kisses his brow tenderly, like he doesn’t knows he’s breaking apart Magnus’ heart and making it stronger in the same breath.
“And Magnus!” Alexander is getting animated now. His brow furrowing like he’s thought about this thoroughly and Magnus marvels, because he must have.
“If, if we had a baby with only my blood. We’d have to find someone to carry it and—“ Alec gives a wrinkle of his nose, “if something happened to me. Custody would revert to the bearer. Magnus the clave would rip our baby from you while you were still watching my soul depart.”
And Magnus watches as Alexander’s eyes glimmer with unshed tears, “there is no delight in life that would be worth the pain it would cause the both of you. It’s not fair to you or a child. To be torn from their only remaining parent because the clave won’t let a downworlder raise one of their precious blood.” He sneers the word with disgust, “and you’d fight them. Because they were stealing the child we had together. Stealing the part of me that’s left—“ and Alexander sounds like his heart is breaking, for this non-existent version of Magnus.
”Tell me, how can I claim to love you and risk that?” Alec asks him, “to ever risk putting you in a position where you’d have to go against the clave without me at your side and having your back.”
And Magnus marvels at how every day, the man in his arms opens his mouth and changes Magnus’ life.
In the best of ways.

It wouldn’t even be difficult.” Magnus finds himself musing, weeks later as the memory of their short conversation plays over and over in his mind.
“What wouldn’t?” Alexander asks him, fucked out and exhausted from where he’s stretched next to Magnus.
“Actually breeding you.” Magnus says with a grin, baring his teeth in a way that Alexander always shivers at.
He does so now, pupils dilating even more until the hazel is swallowed up, a dark shadow of lust encompassing the forest of Alexander’s eyes.
“Yeah?” Alec asks him, voice low and rough as he snuggles just a little closer. He swallows, like he’s thirsty and Magnus clucks his tongue and reaches out, cupping his boy’s face.
“You’d like it if I did it properly, wouldn’t you?” Magnus asks, “if I tethered the magic of our souls together. If I fucked you full and kept you that way, mixing our essence until it takes.” Magnus hums consideringly and runs his hand down the path of Alexander’s back, fingers dipping to tease at Alec’s hole.
Alexander wiggles back, encouraging him to continue and Magnus gives a dark chuckle.
“You’re so eager for it. Aching even,” Magnus murmurs and he slips two fingers inside Alexander, pushing his come deeper in.
Alec is biting the sheet, trying hard not to make any notice that will distract him from Magnus.
“There’s is a ritual for it.” Magnus admits and he adds another finger and presses hard against Alexander's oversensitive prostate.
His boy whimpers and clenches around him, like he’s daring Magnus to try and stop.
“So greedy—“ Magnus says and he stops to finger-fuck Alexander for a moment, distracted by the look of pleasure on his face. “I could do it darling. Give ourselves little immortal babies. Could fuck a little prince of hell into you. Breed you with demonic royalty—“ and Alec gasps like Magnus has already fucked into him properly.
“I’d have to breed you, every day.” Magnus sits up so he can tug on Alec’s rim and feels the way he chases the feeling by moving back into Magnus’ touch.
“Yeah,” Alexander gasps out, “yes. That, please Magnus. Fuck me now.”
Magnus tuts, sliding his fingers free despite the way Alexander clings to him and throws a glare at him over his shoulder and he slaps Alexander’s ass.
“How am I supposed to breed you if you don’t let me in?” Magnus teases and he adores the petulant pout Alexander gives him.
“You’d manage it.” Alexander mutters and Magnus slaps his ass again in response to the sass.
“I would,” Magnus promises as he settles on Alexander’s back thighs and spreads him, admiring how his come is dripping out. “But I doubt you’d enjoy it. My cock and three of my fingers when you’re this sore, you really are desperate for it.”
Alexander groans and then he tightens as soon as Magnus starts to slide in.
He’s as hot and wet as he was when Magnus fucked him in the kitchen.
A meal that Magnus always has available to devour.
“Fuck,” Magnus groans and he digs his fingers into Alexander’s hair and hauls him up. He twists his boy, so that he can press their mouths together.
His balls slap Alexander’s ass and their teeth clack when Alexander stops kissing to just moan, open mouthed and shaking from it.
Magnus pulls back, licks the slick bruise of Alexander’s panting mouth, and shoves his boy back down. Pinning him with a hand to his nape so he can fuck him.
“I’ll have to make some changes.” Magnus muses, necklaces chiming as he rocks his hips. Alexander shudders under him and Magnus wonders how raw and slick his cock is, trapped and leaking against the sheets.
Magnus doesn’t bother with checking, because if he touches Alexander's cock, his boy will come and after the fucking he had earlier, Magnus doesn’t think he can take another orgasm so soon.
“You’ll need to sleep, covered and filled with my magic and come. Every full moon I’d need to find and bleed a nephilim. Feed you their heart with my own mouth and paint your runes with their blood.” Magnus sighs in contentment when Alexander howls and clenches around him. Magnus grinds deep, pinning Alexander down so he can’t go anywhere or do anything but take it.
“I think Azazel owes us. After all he did visit without a warning that one time. I’d rather enjoy using his core to build a soulnest for our child.” Magnus adds a spell to his own body, wondering if he should make it a permanent addition.
Magnus’ hips stutter at the thought, that it would need be a permanent addition and he groans. “I’d open you with my own blood, feed you my blood and come until my magic and essence was eternally stamped on you. Until you were mine more than your own.”
He gets his cockhead kissing Alexander’s prostate and lets himself come, hot and thick and more than should be physically possible.
Alexander groans and tenses, body locking up like he’s afraid Magnus will slip out.
Magnus chuckles, breathless with pleasure and stays close, letting himself drop down on Alexander.
There’s a little whine from his boy. And Magnus shushes him and settles his weight to be comfortable while his cock hardens back up. It won’t take long, not with the magic Magnus has cast or with the way Alexander's begging for it.
Alec’s breathing heavy, body trembling under Magnus’ weight and trying to squirm to free his own neglected cock.
“Settle,” Magnus soothes and he presses kisses to Alexander’s nape. “I’ll fill you up soon enough.” Magnus promises and he licks his lips, wondering how long he can convince Alexander to stay plugged. To keep him full of magic and come and pleasure, belly swollen with Magnus’ claim.
