After being rejected sexual release from your parter, you wait for them to fall asleep, elavate to your haunches and
stroke your donger until you are ready to ejaculate.... at that moment you slap them in the
forehead and yell "surprise" as you paint your
load across their unsuspecting face.
Jim " so did you get laid last
night?"
Dale " no but when she fell asleep I gave her the ol' "Okeana surprise
party" and then wiped my dick off on the curtains"
