He thought about it for a while, before he said "Say it like you mean it." "Oh for- Please, Mettaton?" He smiled. "All right." He returned to his former position, and stuck his tongue inside. Much to your surprise, it started vibrating. You moaned loudly at this. The one thing that wasn't fair about Mettaton was that he could switch between using his 'mouth' to speak, and the speaker in his chest. "Enjoying yourself, sweetpea?" Where in hell does he get these names? "Y-yes." You muttered between long, breathy moans. He chuckled, and curled his tongue, moving it around constantly. "Holy shit, Metta-AH!" You could feel your orgasm approaching.
