Sirius’ girlfriend gets jealous over his and Lily’s friendship, for anon.
“There he is!” Marlene said cheerfully as Sirius’ motorbike came roaring towards them. Sirius heaved it on one heel as he drove, Making her heart heave in her chest as well. The forewheel met the ground after a short while and he took a spin on the left, stopping right in front of them.
“Do you always have to show off?” Lily asked, rolling her eyes.
“Always in front of my two favorite girls.” He winked at her.
Marlene glanced at Lily, her smile frozen.
“So, what d’you think of my new baby?” He asked, patting the bike affectionately.
“Oh, she’s lovely.” Marlene said, raising an eyebrow.
“I know right?” Sirius looked up at the girls, smirking. “Who’s up for a ride?”
“Sure!” Lily cut Marlene off excitedly. “Only if you don’t mind, Marls. I have to come back soon to meet James anyway, we won’t be long!”
Sirius checked Marlene’s reaction. She nodded, but as soon as Lily had looked away, her smile vanished.
“Hey, Lils, you know what? I’m going to lend it to Prongs as soon as I’m back, so he can take you for a ride.” He glanced at Marlene. “Come on, baby. I hope you like speed.”
Marlene’s eyes widened, and she glanced at Lily.
“What are you waiting for !” Lily rolled her eyes, and smiled. “Have fun, you two, and no hanky-panky!”
“We’ll do our best to behave.” Sirius mumbled as Marlene climbed behind him, wrapping her arms around his chest.
“Why didn’t you pick Lily?” She asked once her friend was out of earshot.
“I didn’t have to pick, Marls.” He said, making the bike roar again. “It’s always you.”
“Jealous?” He turned to look at her, smirking.
“Fuck off, Black.” She blushed.
He laughed, and they hit the road.
