You were Sirius Black’s significant other, and have been for almost a year now. You loved him, you really did. And he loved you back, obviously, although at times he was a bit possessive. You had a good life at hogwarts, and it was all well, no issues in your relationship.
Except for one small thing. His mother, Walburga black.
She was a very horrible woman, mother, and witch, altogether. Sometime you’d question if she even had a heart, although you never mentioned it to Sirius, just so he didn’t get upset.
One day, during the summer break, you were at his house, and things were getting a bit steamy between you two. You were making out, sitting next to him on his bed. But at that moment, inconveniently, his mother walked in. He pulled back from the kiss, and they bickered a bit, and went outside without the thought of you there. You heard yelling from downstairs, and then heard footsteps. It was Sirius. He walked in and hastily locked the door, and turned to you.
“…Strip.” He told you, a bit demandingly.
“I want to show my mother, just how much I don’t care about her opinion on us. Even if she hears it, loud and clear” He explained, crossing his arms, waiting for your move.
