A. When you're fucking a girl on her period and she queefs out a cum bubble.
B. When there is blood in your cum and someone takes your load in their mouth then blows a cum bubble like they had a wad of bubblious bubble gum in their mouth
A . All these bloody cum bubbles coming out of your vagina is making it look like Willie Wonka made a strawberry fizzy lifting drink.
.B. You better swallow that bloody cum bubble or you will stain my sheets or towels
The inevitable result of being an absolute unabashed whorebeast that lives only to be pounded by every dick or dick shaped object repeatedly all day errra day. These CBVBB's have every known STD and many unknown ones as well. If you encounter a CBVBB they may be disguised like a woman, a grade school teacher or your mom. Beware of their charms like showing you their tits, grabbing your dick or trying to shove your dick in their diseased puss or anus.
