You would've thought Astarion wasn't one to be jealous. He was always so nonchalant when it came to sharing you with others, or watching you giving affection to the rest of the group. So tranquil and chill. And you liked that! You loathed controlling behavior on your partners, as it should be. But over time, you noticed small details that betrayed his true feelings.
Despite his calm exterior, he would bite your neck harder after having drinks with Karlach, leaving marks for days. Or sometimes, if Shadowheart got too close for comfort, the vampire would fuck you so hard that night you were barely able to move the next day. Laughing at Wylls jokes? He would eat you out for hours on end until you were pleading for him to stop.
But it wasn't just during sex that he showed hints of jealousy. One day, while sitting at the campfire, Gale brushed his hand against your arm playfully as he told a story. You didn't think much of it until Astarion's hand casually slid over your hip and pulled you closer to him, silently claiming you as his own. As his fingers gripped your waist, he leaned in and planted soft kisses on your neck, causing you to blush at the unexpected display of affection. This pattern persisted for days, and you couldn't help but notice that whenever someone got too close or flirted with you, Astarion would subtly place an arm around your shoulders or play with your hair. It was like some sort of game to him, though he would never admit it to you.
The worst came when Gale offered to teach you to do magic. You were surprised by how easily you seemed to pick up the magical arts. Gale was also an excellent teacher, patient and encouraging. It was exhilarating every time you successfully cast a spell or even conjured a small flame in your hand. As you continued to learn and practice magic with Gale, you would excitedly retell your experiences to Astarion. You loved every moment of it and couldn't contain your enthusiasm. And even though he loved teasing and taunting you about your newly acquired magical abilities, he was also impressed by it.
"You truly are a surprising little thing," he would say with a genuine smile as he watched you practice spells.
But soon enough, you noticed that every time you brought it up, he would go harder during the night, making sure you were moaning his name loud enough to wake everyone in camp. After one particularly intense session, you were lying next to him in his bedroll, lightly tracing your fingers over the bite marks on his neck
"Are you okay?" you questioned softly.
Astarion's hand stilled on your back as he looked at you.
"Why do you ask?" he replied, his voice guarded.
"I just... you have been behaving a bit weird lately when I talk about my lessons with Gale."
He just scoffed "I simply find it amusing to think about you spending so much time with Gale of all people; his constant rambling must be driving you to madness."
You raised an eyebrow at his response, not buying it for a second. "Come on, Astarion. I know you better than that. What's really bothering you? Are you jealous?"
