As title suggest, what is that thing that started this, when, how ? What is that thing that makes it hot to think about your mom fucking with someone ? Which way u dream of your mom being fucked ?

My mom had a bit of a drinking problem. I remember having friends come over and she'd be a little tipsy and start flirting with them. She'd touch their arms and compliment their physiques. It was very embarrassing, and I'd always try to avoid her when I had friends over. I guess at some point that metastasized in my head.

Yea i know that feeling, can go too far sometimes, and its easy to make their dicks hard and knowing that they already jerk off to her, my friends used to come to my home just to check her around and stare.

Mainly the judo section, this is the key event that traumatized me because she was being groped (by boobs and ass, taking advantage of the moment in the ground grappling) by a few boys my age (11-12) and I heard them discussing her
After that I had erotic nightmares in which these two boys do whatever they want to her, and at some point she breaks down and enjoys herself
And later I became fascinated with this topic, began to fantasize about what my friends, enemies and so on do with it, a little later, when I began to have a regular sex life with girls, it remained only within the framework of fetish, sometimes I even like to play a bully in role-playing games with a girl.
I think in my case specifically there were just stupid events that broke me, I didn't originally have any cuckold fetishes, now I kinda don't care, I don't think or fantasize about her, I just like this type of content

so at young age i used to go to my friend's house basically every afternoon to "do homeworks" (actually we played videogames and watch porn). his mom was always around the house doing housework and cooking, she was very kind to us and had an incredible ass a and a cumslut face and i fell in love with her and started imagine to fuck her every night jerking off a lot thinking about her. the fantasy got more and more nastier for a little boy, imaging me and my friend fucking his mother together in his room when she entered to bring us some snacks ahah also we use to watch incest porn, so it looked to me kinda ok to fuck your mother.

growing up i got a little bored about this fantasy and one day, while jerking off, i thought about my friend fucking my mother: my dick got hard like never before and i enjoyed myself soooo much. the first few times I felt a little guilty after ejaculating, now the guilt is gone and i just enjoy the fantasy thinking about my mother fucked in the nastiest positions by my friends, coworkers, persons she knows, my cousin etc. i think about gangbangs all the times with me watching her getting fucked and covered with cum.

Is there any bull here pm me I wanna chat on my mom

 I accidentally sent a pic of my mom to some guy I was chatting to on Reddit. And then an hour later I saw my notifications and was  horrified but also so aroused by what he said about her. Tell ing me how he wants to fuck her and how she looks a like a milf. I’ve never heard anyone describe her before that and since then I’ve been craving that same feeling.

My mom was groped by my friends at the age of 12-14 age, and even they could touch her bare breasts (I think it was 10 seconds), but this is with me for life.
I still don't know if it was on purpose or an accident (They didn't even discuss it in front of me once)

That's hot, did they grope her in front of you ? What was her reaction?

Grew up with a (single & young) mom that was considered 'very hot'. 

It didn't bother me when guys made comments about her because I genuinely believed that 'that's just how (adult) women look. All young gets get these comments.'  When I started to realize that it was just me and other guys in fact do NOT have every man around them eager to bone their mom,  it caused confusion & regret. It caused me to wonder 'WHAT IF' about a lot of things and that's where this started for me. Growing up, I did see my mother fooling around with men a few times but it had no effect on this interest. I saw it like: 'Adults have sex? yep' so it wasn't a shock to me.
