nit ducking

When you shove your dick in her a as forcefully when she doesn't want it but then she realizes after a few seconds she definetly wants it.

Nit ducking: Having a her tide up in bed and trying to get it in her ass as she try to say no through her ball gag but you put it in any way then after fighting for a few seconds she starts to really enjoy it, then the next day she's begging for more and she won't leave you alone until you give her more.
