Whine Up - Sirius Black x Reader (smut)

Request: Hi could I request a young Sirius black imagine where Sirius and reader have both been sexually frustrated all day and decide to go back to the dorm;) but just as Sirius is abut to go down on reader the marauders walk in and are all like "OMG MY INNOCENCE" and shit like that. When they leave reader is like no way mood is ruined so they go down to the common room only to have the boys tease them xxx
Warnings: Okay this is a bit more smutty than what you requested. Sorry... not sorry. SMUT. My English. Not that great?
