Incest

It was the first time our parents left me in charge when they went to a wedding.
I was able to get my youngest sister, who was fresh out of a tub bath, wrapped only in a towel, to look at online porn sites that I had pretended to have found by "accident". With the help of the vids I got her to let me lick her vag.
I did my best to copy the vid and my sis seemed to really enjoy it after initially giggling a lot because she said it tickled her. After a little while she sort of started to verbally guide my licks as she held her vag open with one finger from both her hands.
I opened my jeans and showed her my little erection and I got her to touch it.
It was sort of more difficult to convince her to let me put my penis into her but she gave in and I gently slipped into her hairless vagina.
I was thirteen and barely had any control.
I slipped in her and paused. We both adjusted ourselves. She was a lot shorter than me so my chin rested on the top of her head. I could already feel that I was about to squirt. I felt my sister very warm hands lightly grip my waist on either side and told me to go ahead and move like in the vids.
I swear I lightly humped into that warmly moist and firm grip of her vag no more than five times and I let out all my semen into her. My penis went limp immediately as I came.
She was too young to get pregnant but not young enough to not notice that I did not do it to her for the same amount of time that the guys in vids were doing it to those chicks and she expressed her disappointment. I felt embarrassed and apologized.
She was sort of annoyed with me and left for her room while cleaning her bag with her towel. I got scared that she'd tell on me but she never did...but she never did it again with me either.

I would love to see my wife fuck her father our our son. Either would be fine with me

My wife has given our son handjobs when he was 12 teaching him how to masturbate instead of jumping pillows

I found out years later that my wife fucked her dad for a long time before we were married.

I’ve fantasized about my wife fucking her own brother. I think it stems from seeing and reading incest stories. It’s just so naughty and thinking about my wife with anyone is very hot, but the whole taboo element makes extremely arousing. By also the idea of them fooling around together when they were very young adds another layer to the possibility. He used to spy on her, and she would give him a show. If she would only admit how much she wants his cock. Such a turn on to know she’d be so horny and naughty to do it.

Wife and her younger brother did some spying and touching when young. He moved in with us. You could tell they there was awkward lust with them and one night it was so obvious. I got up and said I'm going to the garage and when I come back you guys better be fucking. Came back and they were in his room having a wild time. 2 yrs later they fuck all the time. I watch I join. It's great

You’re not alone in this fantasy. I’m pretty sure my wife fucked her dad around the time we got married but she won’t admit it. And I fantasize constantly about me and my 4 brothers running a train on my wife.

My wife would never allowed anal sex because of her sexual traumatic history with her oldest brother when she was growing up. I filed for divorce.

That’s a good reason for divorce

I did not get along with my brother in law to begin with. He was and remains, an arrogant asshole and I just could not handle finding out about their long term incest. I agreed not to expose them but I insisted that she expose what they did as kids. Eventually she agreed to let me have the house in exchange for my silence.
