All characters are consenting adults.

If you have not read parts 1-3, you should know that my husband (whom I call Daddy as part of our power dynamic) has given his brother (whom I call "Uncle Brian") permission to use my body for his sexual release twice per day while his wife is away caring for her mother in Romania. I have consented to this (and secretly enjoy every second of it). I am not allowed to cum on Brian's cock, but my husband has agreed to give me forehead kisses and orgasms as reward for my cooperation each time Brian finishes using me and leaves. Wanda is a recurring character in my stories. She is a caretaker my husband hired to watch over me when He is at work. We call her my "babysitter," because that is how she functions, and because my husband enjoys humiliating me (and I enjoy Him doing so) by making it seem like I cannot be trusted to take care of myself.

"Where is she?!," Brian demands.
"Calm down. She is thanking Wanda. I got home a little late today, and 'thanks' had to wait until after I was properly welcomed home. I am sure they will be done soon."
"I am not waiting," said Brian impatiently. "It has been a long day, and I need that ass now!"
Brian storms into the room where I am "thanking" Wanda for taking care of me today by licking her pussy and playing with her boobies.
Daddy follows him in and says, "fine!"
The next thing I know, I feel Brian climb onto the bed behind me and start rubbing his cock on my butthole! I can't turn to ask Daddy what is going on or to make Brian stop, because I know better than to stop the rhythm I am working Wanda's clit, so I brace myself for what I know comes next.
Brian pushes his dick all the way into my ass, his balls slapping my pussy, while I continue to try to make Wanda cum with my tongue, my fingers pinching her nipples in the way she likes, her hips grinding her muff into my face.
Uncle Brian is always very rough with me. Today is no exception. "Oh yes, squirt! That tight ass is exactly what I need right now. You are going to enjoy this ass-fucking, you little slut. You are going to be feeling this one for a week!," He says as he pounds his dick into me so hard I am having a hard time keeping my tongue on Wanda's clit.
Wanda must be into it, though, because her pussy is getting wetter and wetter. Figures she would get off on watching someone cause me pain. She is a bit of a sadist. I am beginning to think everyone in my life is. Except for Candy. But Candy is still in Romania, leaving me here to contend with all the sadists by myself!
Daddy is watching from the rocking chair, and I can see He is very pleased. He also looks very turned on. That makes me happy, because I know that once Wanda and Brian have their orgasms, Daddy will be rewarding me with mine. I just need to keep being a good little slut for Daddy and get these two off so I can have some alone time with Him.
"Fuck. Whore! I think your asshole somehow got tighter. How does my fat cock feel ripping it's way through you, you little slut?," Brian continues. (He is so mean with his words when he is using me, but I know he loves me. I am his little squirt. He just likes to degrade me while getting off using my body.)
Wanda starts moaning, "Keep going, babygirl. Just like that. I am getting close."
