I love to tie my slaves up with leather belts and place lingerie pins all over their ample bosoms. There is just something about the combination of leather and wood that really gets me off. And I know by my slaves squirms that they are quite happy with this combination as well. Leather is worthy because of the way it bites… especially into delicate tit-flesh. And I just love to use clothespins on my slave's boobs and always make sure to get a nice grip on her tit with the pins for maximum bite.
