Sirius likes to tease. No big deal right? except his timing is impeccable and he decides to tease you in Potions, the git.
It was just an ordinary Monday morning. Breakfast was bland but normal; you sat beside Lily while Marlene murmured excitedly about Quidditch and Mary complained that she had eaten far too much. Mary loved food as much as Marlene loved Quidditch but that didn't change the fact that both conversations were boring.
Lily listened politely with somewhat mild interest while your thoughts drifted to the previous night. A mess of tangled limbs and skin flush against skin. Heated kisses, dark purple hickies (that you had to cover with magical make-up), and a deliciously painful ache between your legs. Desire trickled down your spine, desire pooling in your panties, and you shuddered.
"Alright, (Y/N)?" Dorcas asked and you nodded quickly, banishing those thoughts away.
First up was Potions with Slughorn. You weren't too bad at Potions, though sitting with Lily improved your skills considerably. Mainly because she often whispered instructions to you and helped you with tricky concoctions, otherwise you were sure your cauldron would explode.
"Okay, class, settle down now," said Slughorn over the chatter of the class. The noise died down to faint whispers as Slughorn began to scribble on the board.
"Since your last assignments were complete disasters-"
"Awfully nice of you, Professor," called Sirius Black from the back of the class and you turned, smirking at the Marauder. Slughorn ignored him. It was habit for Slughorn to ignore Sirius.
"-I have decided to assign you partners that you will sit with for the remainder of the term."
There was an outburst of disgruntled groans from the class, and you gave Lily a worried look. Slughorn's voice rose above the moans of complaints filling the classroom and everyone fell reluctantly silent.
"Here are your new partners, if you could please find your way to their seats, quietly."
Slughorn handed you a minimalistic map of the classroom and you scanned the sheet quickly, searching for your name. You spotted it, but before you could see who you were sitting next to, a voice boomed from the back of the classroom, rippling through the quiet chatter of the class.
"(Y/N)! Over here!"
It was Sirius. Sirius Black. Sirius fucking Black.
Lily raised a teasing eyebrow and you made a face at her. She opened her mouth to make a comment but before she could, James Potter slid into the stool you were previously occupying and you grinned at her. Lily rolled her eyes, her mood souring.
You sidled up to Sirius and dropped your books at the vacant spot beside him. When the class had settled, Slughorn launched into a lecture about different kinds of potions. You focused for most of his speech until you felt a hand on your knee, spreading warmth across your skin. Your skin pricked with goosebumps and desire began to tingle through you as you forced a disgruntled expression onto your face.
"What do you think you're doing?" you hissed.
"I saw you," Sirius whispered, his voice low and husky, "This morning. You shuddered."
"There was a cool draft," you muttered quickly, your cheeks crimsoning. Sirius drew a circle on your thigh and you wiggled.
"I know how your body works," Sirius murmured and his hand drifted further up your leg, tracing patterns across your skin, "I know you were thinking of last night."
