The act of a female rubbing hot, melted chocolate over a mans penis. She then continues by giving the man a regular blow job from where the man ejaculates and mixes in with the chocolate creating a "milkyway". (The milky way is a spreading paste use for multiple activities eg. on bread, that consists of white and dark chocolate)The female can then continue licking the penis where she gets a mixture of both cum and chocolate.
That chick over there gives the best Milkyway's.
HOLY CRAP, that school girl on the corner is handing out FREE milkyways!
