I guess most people would consider this very weird and unhealthy, but my mother and I used to watch hardcore porn together when I was in my early teens.
We'd both been more or less alone since my father passed away (when I was 8) and we lived sort of introverted lives. We always had this "us against the world" thing going on, where we'd make friends in passing but never invited anyone else to really share our lives.
This extended to the men my mother would occasionally go on dates with once or twice, but always blow off before things got serious, and my school friends who might visit a couple of times, even spend a night - before I stopped inviting them.
It just felt normal to us being alone. We were happy, it didn't feel strange.
When we got our first VCR around 1986 (I was 14) and we would rent videos from the little mom & pops video rental business near our home, I'd usually see a porno tape that I was curious about and my mother would rent it for me. When we'd get home we'd pop it in and watch it. When I had questions, she'd answer them honestly.
It didn't feel all that strange sitting beside her watching guys cumming on women's faces, seeing gang bangs or watching two women going down on one another.
Sometimes I'd ask my mother if she'd ever done this or that and she'd tell me. That's how I discovered she'd eaten pussy before and been anal fucked.
If I became aroused, she'd tell me to masturbate. She said it wasn't healthy leaving the cum in once my cock was hard. So I'd take it out right there and jerk with her beside me. Sometimes she'd compliment the size of my still growing cock, telling me how much bigger mine was even at 14 than my father's had been.
I never had sex with my mother, but she did show me her body. We both walked around nude sometimes, say from the shower to the bedroom to put on clean clothes. I was as familiar with her full dark bush and breasts and her ass as I was with my own cock and balls.
Even as we grew older and the VCR was replaced by DVDs and then the Internet. We'd watch all kinds of videos online. And I'd lay in bed beside her or we'd sit together on the couch and I'd jackoff while she patted my leg or leaned her head on my shoulder. She always liked it when I'd cum a lot. So I always tried to really gush for her.
She's been passed away a few years now and I am alone. As solitary and introverted today as ever I was. I miss her. But I also feel sorry for guys who didn't have the same openness between themselves and their mothers.
