Everything was extremely perfect until i saw a boy in my girls only party. Actually, I mistook her for a boy and kicked her out out of the party, all because she is a beta-chester.

the "Port Chester Slap" occurs in only one situation. A guy is hitting it from the back and pretends to cum on the girl's ass. Instead, he cums in his hand. The girl turns around and the guy slaps her across the face with his hand filled with cum. Don't ask why it's called the Port Chester Slap, God only knows.
Derived from the deepest parts of Westchester NY only those who dare to cum on their girl's back have the chance at hitting her with the "Port Chester slap"
Dirty as fuck.
