Sex Maid Husband Fantasy

My husband and I have been married for 7 years, we have healthy marriage as far as people can tell but this year something happened, about a 7 months ago I used his computer and discovered he have a taste for cuckholding (what at that moment I found kinda disgusting) and we talked about it, he confessed he have the fantasy of me serving a younger man as a sexy maid and that the though of me prioritizing this stranger before him turned him on a lot, he even described a escenario about me having sex with this imaginary man and my husband begging me to stop and me answering him that I had to obey my master commands and keep fucking, after that I feel bad for him, as I feel bad for him having this kind of fantasies. some time passed and he then told me that he really wanted me to try to do it at least once for him and that he even had someone interested, we got into an argument but eventually I accepted mostly because I admit I am not exactly the most active woman in bed and he kinda guilt tripped me into accepting, the guy name was Liam and he was 22 and from a family with money, we reunited in his house like a week after and I talked in private with this guy, he was a nice guy and fun to talk to, he told me he found me attractive and really wanted to fullfil his own fantasy (basically the opposite side of my husband fantasy), he gave me a box and told m e to get changed, inside the box was a skimpy french maid uniform and some notes: remember to play you rol as the maid, remember that a maid is owned by her master and his command are the most important thing to you, just stuff to know better how to act, I got changed and when I got out I found that both of then were talking and drinking in the living room, they saw me and then after a small silence I decided to just get over with it and do it fast, I salutet them the best I could and acted as obedient as it was posible, everything was relatively vainilla until at the end my husband asked him if I was a good maid and to give me some ''fun cammands'', the guy looked at me and told me to strip to my underwear for him and them give him a lap dance, I did as I was told and my husband was really enjoying it, and the the guy told me to please him as a good maid I looked at my husband and he smiled,, he got his dick out and he fucked me in front of my husband, he asked me stuff while afucking me, like you are master slut? you love your master? your master dick is the best? I answered yes master to everything and he cummed inside me and then we kissed it was the best and most passionate kiss I ever had, I just exclamed thank you master and played with my breast in front of my husband while I moaned, my husband looked turned on but not really as happy as before, Liam told him he might want to keep me and then both laughed and he told me to get changed into my normal clothes, we leave afterwards but he gave me a phone number to keep in contact with him, my husband thanked me for making his fantasy a reality, but I think this experience changed me, it really turned me on to be fucked by this guy and playing as his maid, being a sub and dominated, I keep the number is secret and I keeo going to liam house and played as a maid form him, he gave more maid uniform every one more skimpy that the one before to the one I use now that is more like a bikini than an actual uniform, I am honest, I like being liam sex maid and since my husband is not always in the city I sometime spend many days in Liam house, he sometimes invite a girl friend he has and he make me have sex with her, I feel really turned on by the idea of my husband finding outabout all of this and me not caring at all and just wanting to please Liam, I feel ashamed at times but I forget in the bliss of obedience.
