This is a universal and infallible principle. When the body exercises a provocative force, the other body has no other option but to react. The girl only needs to put her body straps on for her partner to become alert and the passion to go to his head. To provoke the Action: put on the panties with the smallest straps on your thighs and then place the longer straps on your shoulders so that they cross over at your navel. As they are elastic, they will perfectly adapt to your body shape, unleashing all your sex appeal. Prepare yourself for the Reaction: once you're in his field of vision, there's no going back. You'll have triggered the forces of nature. And, of course, you'll be thrilled to succumb to them.
