clip request:  You enter the room in your black underwear and sit on a chair. Your belly is swollen, you begin to gently twist your finger near the navel, pinch the navel. You say how deep it is, then tug at your belly button to make a click. Then, slowly fuck the navel with your finger so that there is a wet sound. After a few minutes, click the navel, pulling the navel with silks so that the stomach bounces. Slide your finger into the navel and pull it out sharply so that there is a suction sound.
