I just love tormenting you while your dick is locked up and I have the keys. Look at how sexy I look in this lingerie. I mean that's really all you can do - look. You can't touch Me and you can't even touch yourself! I have your keys right here too, but I'm not giving them back. Instead, I'm going to watch you squirm in agony as your cock swells in it's little cage. You look so uncomfortable but I don't care. This is part of proving your love and devotion. You must suffer for Me.
