My master got an idea from a porn and this slave is wondering if its possible and if any of you have personally experienced it...... master wants me to push my cervix out just a little while he is fucking me right before he cums so that he can shove the head of his cock into the cervix and cum directly in the cervix. he is wanting to breed me and wants his cum deeply as possible. any tips on how to push the cervix out? this slave greatly appreciates any tips or suggestions. thanks!
