After our metal bondage exercise series on the treadmill, we thought we’d invent something new for the girls to have a workout. Chaining them to an exercise bike would be fun! Not releasing them until they burn a set number of calories. So we invited our friend Natalia Forrest to try this. Just before she arrived, we thought it would be even better to replace the seat with a steel dildo! Natalia was not so sure about this… and she was right. In her high heels, she was chained to the bike and she tried to get the pedals round, going up and down the metal dildo. It was a lot harder than she expected, but it also felt pretty good! Don’t try this at home though!
