Sol is in bondage, with hands and feet bound and soles up. This girl is extremely sensitive to tickling and goes into total despair when she sees herself tied up and unable to react. The dominant couple takes advantage of their weaknesses, making the most of the soles of the feet and the thighs, which are the most sensitive parts. They will use their iron nails to scratch Sol's back and ass, who has fought valiantly but has not been able to free herself from the restraining ropes!
