[Cyrus already felt the flush starting once Rhys spoke. He had become used to the random gestures and displays of affection towards him since he and Rhys sort of unofficially started being a thing. But it was always the lewd comments that sent him over the edge. He raised a hand towards the people he was speaking with.]

Will you excuse us for a moment, the professor seems to have some urgent business to discuss with me.

[It didn't necessarily mean he was going to bring the older man into the next room and ride him until the party ended. No, that was for after hours. Instead, Cyrus just pulled the man off to the side and turn to face him, expression accusatory.]

Rhys, what on earth do you think you're doing? Those are some of my seventh year students who already suspect something between us and I certainly do not need my students looking at me each day, wondering if I had relations the previous night. I know you were whispering, but good heavens, they must have heard you!

[Aww, so flustered and so quickly.]
