As my cuck, it's your duty to get my man ready for me. I don't care if you're straight, I don't care if you are terrified of cocks that are not your own. What Goddess wants, Goddess gets. You don't have a choice but to suck his huge, veiny dick.
I know it's a little bit intimidating, so I'm going to walk you through it and give you step-by-step instruction. Try not to gag!
