Life with my girlfriend's family

I use this platform as an outlet, it's just a simple account of the things that went through my head. Please don't come with 7 stones hand. The day my girlfriend first took me to her house to meet her family, it was the day I revived a lust for older women that I had always had and also discovered a few other desires. I'd seen my mother-in-law and her sisters in pictures, and the sisters were beautiful and so was my girlfriend, but I didn't think it would create the desires that I had. As soon as I got there, the first thing my mother-in-law did, was give a little kiss in the mouth of my girlfriend, there, although it never crossed my mind to share her with another man, it's a thing that scares me just to imagine, I found out that I liked to see her with other girls and this aroused several thoughts in my head, since she didn't tell me much about her past (except that she was almost abused) and I knew that all her sisters were Bi, in addition to being my submissive, this made me imagine her as my cuckquean. That weekend, I died of a hard-on, her sisters are always in see-through pajamas, no bra, just panties, I can always see everything. Not to mention my biggest crush, my mother-in-law, since I was young I've been in love with older women, and my girlfriend's mother charmed me, and I went crazy, she gave underwear as gifts and other sleeping clothes that she didn't wear to my girlfriend, my imagination ran wild. One of her sisters have open relationship, it also made me think things, as I had already said, of my girlfriend being my cuckquean, doing ménage with her sister and etc. I know it's wrong, but the relationship I have with my girlfriend always makes me think about certain things, since she does everything I say. Dating my girlfriend has reignited desires that I had as a teenager, I don't like it, but I can't help it. I never think about cheating on my girlfriend or hitting on her family or anything like that. I have nothing to complain about, and whatever it is, it will be.
