Bike messenger Jan and his boyfriend Lance enjoy their day off and want to have a bike tour but Jan is called to replace his colleague who is off sick. His pipe is full of energy so his first customer learns a lot about how messengers relax with their tools. Jan has plenty of cream to offer and the attorney is pumped up to his ears without mercy. Even the secretary can release some hot air! On his tour de strength around Berlin, Jan gives his customers a taste of his horny instrument. Each hole is being plugged until all air has gone from the pipe. Suddenly Jan discovers his ‘ill’ colleague laying in the sun. The punishment is hard and immediate. No escape is possible till he asks for mercy – big mercy!
