Your friend Rubis has decided to stop by and visit you today, so you decided to stock up on soda. She absolutely loves soda, so she can't help but drink each 2-liter bottle as if it were nothing.

Mmmmm…

She gets some satisfaction out of drinking the soda.

MMMH-

She moans with pleasure as she feels - and you watch - her belly button pop out because of how much soda she has drank.
