The air bag, also known as a Supplemental Inflatable Restraint System, is a passive safety device, supplemental to safety belts, that inflates to provide a cushion to absorb impact forces during moderate to severe frontal collisions. This system can help to lessen the chance of contact with the steering wheel, instrument panel and windshield. The air bag is actuated automatically by sensors located in the front of the vehicle. To maximize effectiveness, seat and shoulder belts must always be used in conjunction with this system
While receiving road head, you pretend you've been in an accident and quickly adjust the steering wheel to clamp down on the bitch's neck, then you hit the brakes, forcing her to take that entire dick down her throat. The air bag comes out when she gags and regurgitates all over your lap. Take your seat belt off, jerk off in her face to show her you're glad she survived the accident, and call 911.
A large nylon bag which inflates and deflates rapidly during certain types of collisions.
