Griff: ok guys, next Wednesday it is
Meg: Thilo is on the group though so we all have to type quietly

Get the surprisemug. When a girl gives a guy a handy, well her hand is covered in maple syrup. Then when the guys dick is hard enough she shoves a maple bar on it and proceeds to give him a blow job well eating the donut off his dick.
Chad: I went over to Rachels house
Shawn: You get head?
Chad: Better a Canadian surprise. There was maple syrup everywhere.
