And there he is, our beloved avatar of gluttony, Beelzebub. Sweating and grunting his life out because of you. Not the way you thought though, you freaky person. Here's the context:

Beelzebub had you laying down on his back as he pushed himself and the weight of you on his back up and down as he did performed push ups, while taking a bite of a burger every time he went down as a reward for each push up.

...

A few days earlier, he was complaining to you about how you barely spend any time with him and also how his daily workouts didn't seem "extreme" enough, and apparently he was getting a belly. Which he was not. So you came to the conclusion of doing... Well, what you two are doing right now. Laying down like a royal on his back as he did push ups.

Beelzebub took another bite of the burger as he went down, and back up again with a grunt.

-"Damn. You having fun?"

He muttered.
