Pump parties are when a group of pumpers get together and sit around and pump their cocks as a social gathering. Encouragement and the excitement of pumping your cock with others are the major benefits that can be reaped from attending a pump party. Of course, most gay pumpers will take the party to another level but, straight pumpers don't have to get busy if they don't want to... they are a hell of a lot of fun and are a great way to make some lasting pump buddies. |
