Bellyhug 

Such a close hug that there is almost total belly contact. Takes place most likely in bed, with your significant other.

Can't we just lay on bed and bellyhug for an indefinite amount of time, Teun?

Yes, Mila. I'd very much like to.

When you go down on a girl and her belly sags over your head.

I went down on hefty Sarah and got a Bellytubby
