When A man has sex with a girl during her period so that his cock is all bloody. When hes about to cum, he pulls his dick out and lets the cum drizzle down his dick making a swirling effect of the blood cum mixture on his dick. Then he makes the girl suck his dick (he may have ass-fucked her earlier for the extra bit of self esteem this will take from the girl), then he wipes whatevers left in the back of her hair, where she can't get it out.
Gardiner: So what did you do with your bitch last night?
Steve: Well it was her period, so I gave her the old Russian Candy Cane, even wiped it in her hair!
