It was Remus’ birthday, and you, his secret girlfriend, just had to ruin it.
His parents had thrown a nice party and invited his friends and some family. It was sweet, really. There were a lot of treats.
You were his girlfriend. Of course, he didn’t tell anyone as you were a Slytherin. His friends were already wary of you as a friend if they knew you were making out in broom closets. It would be over.
Once introductions had been finished and everyone settled into groups, the two of you disappeared into his room to do…Well, you two were making out. You called it his birthday gift number two.
And then his aunt wanted to talk to him. And then Sirius wanted to talk to him, so naturally James and Peter followed, so his parents stuck around to see what the grouping was about, and your fate was sealed as soon as Sirius pushed the door open to see Remus holding you up against a wall by your thighs, making out with you hungrily.
“What the hell…” James gasped, and Remus’ father’s eyebrows knitted together.
