(This audio opens with a very loud burp and includes more burping sounds throughout) You're the submissive service pet to a very fat, very dominant gainer. After a massive meal, he lets out a huge burp and demands you clean the desk off for his next meal. While you clean, he comments on how plump you've been getting recently and plays with your ass. He even has you bend over the desk and sinks his teeth right into your cheek! Master then demands you rub his big, bloated belly to help make room for his next feast. While you work out some burps, he praises you for being such a good pet, and he even allows you to play with his growing moobs as a reward. You can't help but get excited hearing all his praise and rubbing all his fat, especially when he wraps his big, meaty arms around you to pull you nice and close. You end up grinding against your master's belly to get off while he teases you about how much fatter he wants to become.
