If someone puts a dick in your mouth and you do not want it then there are two options:

a. If it is not hard, bite it.

b. If it is hard, bite until you taste blood but not clean through and then keep your mouth at that level of closed, maintain neck position and get away from him ASAP then when he is like you just shucked my dick like a piece of corn you spit it in his face and say find a magistra to sowe that on after you spit what ever is in your mouth in his face then say no means no and walk away from the sub thing that will hopefully succumb to blood loss.

Also, long hair is dangerous if he catches you

I call option B the banshee kiss
