Master Series Frozen Deep Throat Desensitizing Spray. Freeze the throat of the doll with this particular gag inhibiting spray. Simply spray gently to make a numbing effect, wait 5 minutes, then you're prepared to play. Frozen includes a mild numbing agent that jackets the rear of the throat, assisting to suppress the gag reflex and stop discomfort during dental sex. The wintertime mint essence won't overwhelm, and could then add physical tingling for that receiver too. Size: 4 ounces. Active component: Benzocaine five percent
