Her cum slut- a cuckold life

She's turning me into her cum slut. I didn't expect that. It started out with just a little cum. Most of it had already dripped out of her pussy before she put it to my mouth. I thought it was a joke but I played along. I licked her clean. And she liked it.
Soon I was watching her fuck other men and beg for their cum. She'd beg for them to cum inside her so that I could clean it up. Lick it off his cock. Suck it out of her pussy. Sometimes she even comes home from with a cum filled pussy and demands that I clean her. I don't even know who she is fucking at work. But I know he cums a lot. She's turning me into her greedy cum slut. Because now I want it. I want it all the time. I love to watch her get her pussy pounded. Getting treated like a slut. But I wait for my reward everytime. My reward for being a good cuck. For standing in the corner in my panties like she told me to. Watching that big black cock stretch her pussy out of shape. Waiting for him to cum before I'm allowed to. And in the end he will groan and spill his seed into her. Deep inside her, all that warm salty cum. I am truly her cum slut now. And will be forever.
