similar to a regular vagonion, only this time its performed with a red onion. well...a red onion is the product. The male this time inserts the WHITE onion into a women's vagina during her period. But he needs to fit in the entire onion to make it a red onion, or a bloodvagonion.
take note that a vagonion/ bloody vagonion can be done in regular form or rape.
"Charlene was totally having her period, so I gave her a bloodyvagonion, she liked it."
