someone do that for selfdefense,someone for a strange fetish, someone for revenge, someone for fun... most girls have done it once at least and others even many times!Considering women of 25 years old 9 on 10 have even done once at least...where it happens often there's a boy on the ground for the extreme pain and often there's a girl laughing or smiling...probably you have already understood, i'm speakin of a good kick in the nuts, a classic kneeshot to testicles or a hit there, just where that hurts!!! yes, i like that kind of woman!!!!!
