"You think... I care?" Dib replied. Zim groaned and tensed, feeling Dib's pace hasten. He tried to turn to face Dib, but his leer did nothing to stop the frantic human. "I said I'm gonna fuck you," he grunted, "'til you bleed."
Zim felt soreness all up his back, and as Dib whispered sinfully into his feeler he started to claw at the floor. Dib gripped his arms as he pounded him, making it impossible for Zim to crawl away.
