This guy is sly and he knows how to charm girls in a way they don't see coming. He knew he did not stand a chance with these girls and he had to find a way to get inside their panties. So he passed himself off as a tough guy and one who could withstand a lot of pain. He asked them to trample him and they eagerly did. They were mesmerized with how he did not make a sound as they trampled him with their bare feet and that is how he managed to nail them.
