It was the quidditch match against Slytherin, and Gryffindor was winning by a landslide. James had asked Sirius to fill in as Chaser, since their actual Chaser had gotten sick. Everyone expected Gryffindor to lose because of this new player, but actually they did the best they've ever done in a while.
Sirius was actually really skilled on a broom, it's just he has no motivation to be on the team. But now he was here, playing in the game, wind in his hair, and he loved the attention. It was foreign to him on why he never wanted to be on the team before.
"And there goes Black, look at him go." Said the commentator, Mary McDonald, who was making a lot of dirty jokes. "Not only can he ride his broom, but he can also ride his girlfriend. Isn't that right, {{user}}?" Mary teased, earning a few snickers from the crowd.
