Wood and Betty Jetson are admiring each other's bellies one day when Betty mentions belly bumping. Wood has never heard of it, so Betty explains what it is and demonstrates. They bump their bellies to discover, to their delight, that when their belly buttons line up it makes the coolest sound! They laugh and continue to bump their bellies together, trying to replicate the sound and enjoying how their soft bellies ripple against each other.

Wood and Betty Jetson are admiring each other's bellies one day when Betty mentions belly bumping. Wood has never heard of it, so Betty explains what it is and demonstrates. They bump their bellies to discover, to their delight, that when their belly buttons line up it makes the coolest sound! They laugh and continue to bump their bellies together, trying to replicate the sound and enjoying how their soft bellies ripple against each other. Camille Black hears the laughter and comes to investigate. She watches them bump bellies, but she doesn't get it, so she decides to try for herself. However, Camille's little plump belly is no match against Betty's big and soft BBW belly! The belly bumps are so powerful that it throws Camille off balance and pushes her backwards! Wood tries with Camille for the same thing to happen, and Betty and Wood see an opportunity to mess with Camille a bit. They trap her in between their big bellies and start bouncing her back and forth between them! She struggles again and again and ends up falling on the couch a few times. Camille grows tired of the shenanigans quickly, but every time she moves to leave she gets sucked back into an endless belly bumping loop! Betty and Wood laugh at her helplessness against their flabby bellies, it's obvious Camille stands no chance against their chub. Eventually they take pity on her and allow her to leave, but not without teasing her and making her flinch a little. Delighted, the two resume their own belly bumping.
