Cucky and I have always loved CBT, but recently we've taken a deeper dive into CBT related toys. My favorites so far have been spiked chastity cages that have adjustable spikes, so that I have complete control over how much pain cucky is in. I LOVE to see him squirm and whimper as I adjust the spikes deeper and deeper into his useless cock. The best thing about spiked chastity cages is that the more pain cucky is in, the more turned on he gets. The more turned on he gets, the harder he gets. The harder he gets, the more pain he is in. It's a deliciously sadistic cycle!
