CKE18 - Sinking Beads

Machiko is proof positive that bead thongs make girls get extremely excited. We wanted this video to be very intimate so we spent a lot of time shooting and enjoying every small detail of Machiko's lovely body. As time went on we started noticing that the thong's beads were sinking deeper and deeper into her increasingly wet pussy. The more she touched and rotated the beads, the further the beads went. As her little lips became hotter and pinker, she began to get nervous, but we assured her that relaxing and enjoying herself would make for an excellent video. What advise would you give Machiko during the shoot?
