Venus and Mibby are bored in the bedroom when they start to notice their lingerie. Mibby plays with Venus s swollen belly, and makes a raspberry on it. Venus is very surprised and indignant about it, and this triggers a small battle between the two.
They roll around in bed tickling each other, licking their belly buttons, smelling and biting their bellies and have a lot of fun with the noises that the raspberry makes on their bellies and belly buttons.
