Why, fuck them of course!

Silently, Aaralon removed the invisibility spell from himself and walked around behind Xander. As luck would have it, Xander's ass was right next to the pot of oil that Aaralon had used on the Grand Mage when he gained control of the old mans mind, dipping his fingers into the oil, he used them to start lubing up Xander's asshole, ready for the pounding of a lifetime. Xander moaned around the old mans cock as he felt his ass being prepped for entry

Once Aaralon was satisfied that he'd lubed up his young thrall enough, he then dipped his cock into the oil in order to aid the entry process. Once he'd got a good enough coating, he knelt behind Xander, raising the young mans bubble butt to just the right height for fucking. Lining the head of his monster cock up against Xanders boy-pussy, Aaralon eased the head in, making Xander groan around the Grand Mages cock, sending a shiver up the spine of the old man as his balls started churning. Aaralon eased the rest of his cock into Xanders ass and stayed there until Xander was ready to move.

Unfortunately for the Grand Mage, as soon as Aaralon had entered Xanders ass fully, Xander let out an almighty groan that was muffled by the Grand Mages cock that had just started cumming down his throat. The Grand Mage withdrew, gasping for air, he'd forgotten just how good Xander was at sucking cock, better even than him!

"Xander, are you willing to give yourself to me, to be my thrall, my servant, my cumdump?"
