Me and Mistress Roberta both just love to use Our strap-ons on slaves. And the pleasure is bigger when the slave is not enjoying it too much, but suffering.This cock-hungry bitch loves to be ass-pounded. When he sees Us put Our big cocks, he starts dripping in his chastity device like a broken faucet. He loves being Our strap-on bitch. That is why this ass-fuck will have a twist: as long as Mistress Roberta is fucking his man-pussy, I will put a pair of clamps on his nipples and will progressively add weights to them. Weights that will swing, pulling on his nipples even harder when Mistress Roberta fucks him hard. He begs Us to take the nipple clamps down, but they can only come down when My huge strap-on goes up his ass instead. It’s his choice which one he gets: pain in the nipples or pain in the ass. For now, I will take the clamps down, just to put them back turned 90 degrees, for a little more pain.
