Keeping My Legs Open for Sir

Description: Sir informed me that i've been far too wild and that he wants me to start doing my own slave training when he isn't home. sir has instructed me to pop in a gag, shove my head under the sofa and handcuff my hands to both feet of the sofa, have my ankles cuffed. the hard part is that i must keep my legs open so that i don't allow the leg irons chain go slack at any point.
