When a girl has her period and her partner takes a straw and sucks out the blood and then spits it in her mouth and then cums in her mouth.
Dude, I totally did red fusion to Anna last night, but I missed and there was blood everywhere.

Red Fusion, a red version of Dr. Pepper, tastes just like it, only its red, it might have a stronger cherry flavor in it, then the original Dr. Pepper
Give me a Red Fusion or a Dr. Pepper, it doesn't matter.
