I'm going out to do whatever I want, and you are staying home where I can keep your sexuality locked up tight. Don't get any bright ideas, because I'm the one with the keys, and I'm going to decide exactly how safe your manhood is while I'm out doing whatever tempts me.
Maybe I leave you alone and trembling in chastity, maybe I bring someone back to toy with the idea of you, maybe I flirt with strangers while you listen and ache. Either way, you will be locked, ignored, and deliciously helpless until I say otherwise.
