I tested my daughter's panties with a kit from www.infidelitytoday.com and found something that shouldn't be there.

Bloody Flowback(noun) is the term used for the substance that comes out a woman when you are having intercourse. When she is "on the rag" once the male has had his fill and finished unleashing his manly fluids inside her, the red/white cum/blood that comes back out is Bloody Flowback.
