I would tie her in a strict hogtie, fingers also tied. Then I would tie her hair to her toes, forcing her head backwards. Then I'd put a nice big ringgag in her mouth and start using her mouth.
make her stand in front of me and spread her legs place one foot on the chair so I could see and touch her, she would not be allowed to move while I play with her clit, and if she does she must kneel and take itin her mouth.
