Both...

Aaralon noted that the Grand Mage didn't wear any undergarments, which made him smile at how easy this was going to be as he'd already noticed a pot of oil by the desk that Memp used to lube his cock up. Coating his finger in the slippery oil, Aaralon lubed up his finger before inserting it into the Grand Mage's asshole. Finding it easier to insert his finger then he thought, Aaralon quickly and quietly used another of Memp's spells to make his cock longer and thicker.

After dipping his cock in the oil, Aaralon slowly eased his cock into the ass of the Grand Mage. Noticing that even with the paralysis spell, the Grand Mage's cock had gotten erect, Aaralon whispered in the old man's ear.

"You dirty old man, you're loving this aren't you? Well, I'll tell you what I'll do, I want to hear you moan as I fuck you good and hard so I'm going to release the silence spell, but any attempt to use your magic and the spell goes back on, are we clear?"

Giving the old man a gentle thrust, Aaralon wordlessly removed the spell of silence.

"Oh fuck, you're way better then Memp ever was, he was the only man to ever fuck me... OH GODS!"

Aaralon smiled as he sped up his thrusting and enjoyed the sounds of his flesh hitting the old man's ass as the Grand Mage whimpered like a common street whore.
