Harry says nothing. They both know the rules here. He bites back the urge to ask if Malfoy’s okay with this, if he’s sure. Beyond being insulting, Malfoy knows his own safeword, knows he can withdraw consent at any time. The Vows they both took will enforce it, pushing them physically apart and notifying the staffers two floors below them. But it comes at a price – revoking consent also voids the Nondisclosure, which means Harry could go on to tell the entire League how much of a sore loser Malfoy is.
