When a woman is on her period and has had a load shot into her pussy she blows a bubble out of her vagina held together by cum and blood until it pops.
After having vaginal sex with Diane, Ted proceeded to eat her out. He soon found out she was on her period when the tip of his tongue popped her bloody queef bubble and sprayed blood and his own splooge into his mouth and the back of his throat.
