He's starting to adjust to the foreign sensation of having a cock in his mouth when Professor Rammsteiner suddenly pulls away. The head of his cock pops out from Jade's mouth with a wet noise. The disturbance has Jade looking upwards, exasperation written all over his face.

So much for Professor Rammsteiner calming down once the Imperius Curse wears off.

"What do you think?" He asks scathingly. He shifts forward, still lying down, reaching for Professor Rammsteiner's cock once more. "Relax. Let me finish."

The sooner they finish, the better. It's not as if Professor Rammsteiner has to do anything but lie back and enjoy himself. Jade doesn't really see a problem here - maybe his former teacher is just disoriented.
