A finishing move where one pulls out, ejaculates on their partners cleavage and uses the ejaculate as lube to tit-fuck them. With proper timing you may experience a second orgasm.

During period sex, pull out, tit-fuck your partner then ejaculate their own blood into their face. Using the blood on the shaft as lubricant is key.
I'm not kinky or anything, but I would let Burt Reynolds do the Manhattan Clam Chowder on my period.
