My slave has a love hate relationship with these. As soon as she sees me bring them out she starts to cry. I put them on her and then bend her over and apply the correct number of blows to her ass before shoving my dick up her pussy. She comes immediately! Which I like as that means I can beat her ass some more. The best time for me is just after I take them off her and use my mouth to reround her nipples. If she did not have a gag in her mouth she would wake up the whole city.
