Of course that's painful but at the same time very ENJOYING for the brave well trained woman who is always spreading her thigh in order to perfectly offer her vagina to the hard strokes attaining moreover her clitoris : no feminine sexual part is spared in such a good game....

Oh arousal.. A pussy receiving corporal punishment in the form of a massive amount of kicks. The pain is real and obvious, and often unbearable to the victim whos knees buckle many times. Im a fan of genital punishments and this is really great stuff. Real obvious genital pain here, into my fav list and fap hard to it. And even more tomorrow
