As a dedicated slave you shouldn't distract yourself with such unimportant things as boners. I'm here to remind you that you indeed are nothing but my bitch. You're here for no other purpose than to serve me. Your mind slowly molded and manipulated with chastity exercises I decide that keeping your useless cock locked up forever is the best thing for you and me. Let's be honest - it's not like you're going to get laid any more anyway
