A tape gag is, as the name suggests, a type of gag that involves the use of sticky tape.
The most commonly used types are duct tape, gaffer tape and PVC tape from two to three inches wide. (Bondage tape should not be used, as it does not adhere to skin.) Tape gags are the simplest gags to apply to someone. If the captor doesn't want the gag to fall off, he/she must wrap a long strip of tape around the lower part of the person's head, covering the latter's mouth while ensuring that the gag will not slip off. A strip from ear to ear under the jaw helps to restrict jaw movement, making the gag more effective. On some occasions, a top may add a comical touch to the gag by applying two strips in the form of an "X".
Note that a tape gag can cause the skin on the lips to be ripped off. It can also irritate the lips and cause fever blisters in those who have dormant fever blisters cold sores. Tape gags can also rip hair off when wrapped around the head. The longer you leave the tape on, the harder it will be to remove it from the skin.
Note: Tape gags can be combined with stuff gags for extra effectiveness.
Though ball gags and bit gags are preferred during bondage play, tape gags are often used when neither is available. The top may also use tape during a roleplay where a ball gag will be inappropriate, for example, a kidnapper and captive scene that does not immediately lead to sex or kink.
Caution: Note that it is easy to choke on the stuffing inside of your mouth so excercise caution.
