My Husband Young Brother

My husband invited his young brother to stay with us for a few weeks, he is quite fun and have a strong personality he is kinda of a nice guy I guess but I noticed him always checking me out and well, he is stilll very young so I though it was normal and I tried to not make a big deal out of it, everything was normal until my husband had to leave for a job and he is going to stay away for some months, my husband asked his brother to stay here and help me take care of things, after we were alone he began to act differently, he was more actively trying to spend time with me also he liked spanking me in a joke like manner, one day I was in my room and I was getting ready to send a hot photo for my husband, I was wearing a french maid bikini he bough for me, I was testing some poses and then I hear my husband little brother telling me ''that is a hot one'' I look behind me and he was staring at me and he said that I was a really hot maid and that he would love to have a maid for himself, I got closer to push him out of the th eroom but he spanked my ass and walked away, I feel kinda dirty saying this but that turned me on, afer that we was more talkative and we actually spent some daily hours together, one day the maid thing came out, he told me to prepare him some tea and I asked him why, he said ''because you are a good maid'' I remebered what happened before and got turned on and played his game, I answered yes I am a good maid, he then said ''good maids are obedient''I answered yes, good maids are obedient, he then asked m eif I was a good maid and I said yes, I am a good maid, ''and I am your master'' and I said ''yes you are my master'' after that he told me to get changed into my maid clothes, he followeed to my room and I undressed and dressed in front of him for his pleasure, after I finished he put his hand in my ass and he felt me up and then the rest of my body, and asked me ''what a good maid should say'' I just replied with a thank you master, I spent the rest of the day just being his maid and that turned me really on, after that now we normaly spent the day doing our everyday rutine until he say, ''get me some tea'' and I just answer yes master, I get changed into my maid clothes and my maid rutine begins, I have been always a sub but I keep it under control, my husband was not really dominant but he was ok, but is just too hard to resist my sub urges now and I feel I am giving up more and more, at first it was just acting as a maid, get spanked, obeying him and callin him master, but lately he ask for more and when in my sub persona I just cannot say no to him, I strip danced for him, I acted as I was a sexdoll for him, he told me to say how much I love being my master maid instead of my husband maid and I did and it was really hot, I feel things are geting out of control, but is easier to play along, is just too hot.
