and got aroused enough to jack off?

I have a bit of an incest fetish, and I wonder whether it might have developed from having as a kid overheard my parents having sex.

Considering there's a reasonable amount of people here who are into (at least) the fantasy of incest, maybe there's a connection to a similar shared experience.

Yes, quite a few times. And not always with each other.

I’d sometimes hear my mother getting railed by whoever she was dating at the time, and it used to turn me on, but I don’t have an incest fetish and the whole mother daughter thing doesn’t do it for me. It was more just about sex taking place at all within earshot I think, and sometimes the specific guy.

Ever wanted her guys?

A bit, yeah, but I guess it’s a pretty normal reaction for young people to go through at that age.

Sure did! Rubbed my pussy to it every time, and I did my best to try to cum when Mom came! :D

That's only good until you walk in on your grandparents fucking.
Admittedly I didn't give a shit about jacking off (Seriously, why would I? I was 8.) but it's taken me more than a month to unsee what I saw.

Yeah I have but I did not enjoy the idea and sensation so I ended up just putting my headphones on to listen to music to drown out the sexual moans and creaking of the bed.
I'm not going to stop them since it's a natural thing for people to do but damn annoying when you are trying to sleep.

I overheard my neighbor's daughter having sex through the wall next to me, it was definitely nice to listen to. She was moaning pretty well ;)

I would always listen to my mom having sex with her boyfriends. I've only seen her have sex once and it was incredible.

She sounds amazing while cumming

To answer your questions in order.
Yes and no.

I have no sexual attraction to my mother and the only time I heard it was recently when they both came home drunk on their anniversary and forgot to close their door. I closed mine.

When I was around 13 I had a question about something so I walked over to my parents house and knocked, but no one answered. I quietly opened the door, turned the corner and saw my dad railing my mom in missionary. I stealthed back out and walked back home, not so much scarred, but wondering why they a) left the front door unlocked and b) didn't shut their bedroom door.

Yeah, actually I have overheard my parents fuck when I was 16, lol. I remember being in my room playing the ps3 one night and I started to hear moaning and load thumping. Obviously I knew what it was. I got so fucking hard and horny. I went to my parents room, cracked the door open just a little bit to see my mom riding my dad in a cowgirl position. I jerked off and I had cum really fucking hard. I honestly don't regret jerkin off to my mom.

Heard it, did not want to think about it...

Wow! That's one cool mom you got there! Unfortunately or fortunately, I don't think I've ever heard or seen my parents having sex, but if the was the case, I'd probably masturbate to the noise too.
