My girlfriend's girlfriend
Polymory headcannons, Jace x Clary x reader.
General masterlist
Being in polycule with Jace and Clary includes:
🪶 Being the most protected person in the entire universe. Nobody dares to mess with Jace and Clary, nobody who knows how bad your girlfriends temper is or how overly caring Jace can get. Both are dangerous, influential people with well earned reputation, known for not being afraid of sacrificing themselves for whom they care about.
In addition to your lovers watching over you all their friends and families keep an eye on you as well. Clary and Jace usually buy you lots of weapons as gifts and give you free, regular fighting lessons to make sure you don't have to rely on them for protection.
🪶 Quiet evenings when Jace plays piano for the both of you and Clary paints. If you are also an artist they definitely find this quality extremely atractive.
Sometimes you and Clary dance to waltz played by Jace, bare feet gently thread on thick, soft carpet and rain falls down tapping on the window. Her red hair frame her face gracefully as her talented fingers firmly grasp your waist. Fiery passion that makes your body shake, felt through her fingertips, awakens something in Clary. Next thing you know she teases your body with her painting brush, writing down love confessions in red and gold, cold paint contrasting with hot skin. Each letter and rune engraved in your memory, even after she smudges them with her fingers.
Every time she made love to you, you felt like a piece of art, precious and valued. Concentrated look on her face paralelled the one she had when she created new runes, and you could've sworn her touch felt like heaven itself, warm and soothing like light radiating from signs drawn by her hand.
🪶 Falling in love with Jace all over again each time he rests his head on your knees during his naps. The way sun kisses his incredibly handsome face, highlights the bridge of his nose and his cupid bow, giving his golden eyes this deep, warm glow - your heart can't stand this perfection. Sunlight plays with golden reflections in his hair, making you play with soft strands. Against your fingers they feel like fur of a bunny. Your hand strokes his head, neck and collarbones, while your gaze follows the path to his well defined chest and abs, reminding you of an ancient greek statue. His muscles flex as he sits up, giving you teasing smirk and pulling you on his lap. He embraces you with strong arms and whispers words of passion in your ears.
His long, beautiful fingers find all your weak spots with perfect precision, tracing a delightful path his confident mouth will soon follow until you sing for him again and again. Your defenses and insecurities melt under the heat of his desire, like snow under rays of spring sun, engulfed by his love.
The way his golden eyes looked at you during such intimate moments reminded you of honey. So sweet and natural, primal in a sense. Just like with sweet treats, you just couldn't get enough.
🪶 Taking care of their wounds. You always worry so much about them when they go on a mission without you, but they are way more experienced on battlefield then you, so they often get missions they can't take you to for your own good. Jace promises that once you are good enough they will take you with themselves always, so you don't worry. They often get hurt, but it's something they are used to and usually they quickly get themselves together after purifying and healing their injuries with angelic runes.
Yet, not all wounds can be treated like that. Sometimes certain people and objects from darker dimensions like Thule can get through to your world and cause more harm than anybody could've imagined. When you saw effects of certain weapons, rumored to be Sebastian's creation, on your lovers skin - you were terrified. It looked like cancerous venom trying to grow into their bodies and take over their light. Thankfully, such awful energy can't stay intact in healthy realm. It's impossible for it to coexist with angelic blessings. Still, healing process is slow and painful. No matter how strong and resilient are your lovers, you always worry.
Your heart breaks when Clary hisses, as you engrave runes into her skin or when Jace's body gets all stiff as you wash his wound with holy water. You always saw them as invincible and those moments of weakness remind you of their mortality.
🪶 Once a year the three of you spend the night in bothanical garden, watching how your favourite flower blooms for one night only. It's like a celebration for you, you always cook and bring your favourite foods, sometimes you even open a bottle of good wine. You talk about all great things you accomplished this year, as a couple and individually. Tender promises of another precious year, one of the many more to come, are whispered among you alongside words of praise and affirmation. All confessions are renewed. Soon, words of affection turn into kissed and caresses exchanged equally between all three of you.
The first time they took you there and explained how much this place means to them - it was everything you needed to feel as their true partner. It took them a few years but it was worth the wait and you look forward to it with lots of hope for future, knowing your heart is in good hands.
🪶 Being the only person whom Church accepted from the beginning. Imagine shock visible on everyone's faces when he approached you out of his own will and let you pet him, few seconds after Jace told you to not worry about the mean cat who initially dislikes everybody.
He wasn't the only one who quickly got attached to you. You are officially favourite auntie to Malec's children, always bringing them homemade cookies and teaching them new, cool things each time. Drusilla also quickly became a friend of yours, sometimes you meet up just to put on gothic make up (that you taught her) on and watch scary movies.
🪶 Becoming safe space for your partners. This lonely, scared little boy inside of Jace has found safety and understanding in your and Clary's arms, finally feeling loved and validated after all those bitter years.
Clary knows she can confess every single one of her feelings to you and Jace, you won't consider her too dramatic or emotional. Both of you appreciate her hotheaded and fierce nature. You both admire how she stood strong among the confusion and prejudice of this mystical world in its darkest hour. She feels like you both are strong foundation she can lean on and build her future on.
