Wow, such a hot video!
First, your muscular abs are just prefect, strong and visible, but in a healthy way: not extremely thin or slim, but with a proper volume of breath behind it.
Second, real punches and kicks while blindfolded. No weak abs tapping here. You are so incredibly tough!
Third, I perceive a unique "slutty" attitude, willingly opening up your belly to the punches, again and again. So hot!
