Once you've crossed the line, there isn't any problem. It takes a little bit of psychological adjustment and if you get that right, and you accept that you're never going to be understood by anyone on the outside, then it just becomes a world within a world.
You know that most of the stuff that happens is ugly and dysfunctional and most probably non-consensual, but not all of it. And no-one wants to think that any of it is going on by choice, or even worse, to consider that it's better than anything you'll ever experience with anyone else.
But when I fuck my mother, when she takes my cock in her mouth, when she calls out to me to watch her frig herself with a dildo, it's sex beyond the firewall. That's when the fantasy of super-heated sex becomes my commonplace; all the purely animalistic instincts which are repressed or just partly expressed between regular couples blaze into life and there are no limits. We are of the same flesh and together we are unconscious of propriety. Whatever we want we take and give.
None of this would have happened if mother wasn't hyper-sexual of course. She had a kind of mania for it and the doctors wanted her to take drugs, figuring there was a limit to how sexually fuelled a person should be. They reckoned she had gasoline dripping onto a fire that was already stoked too much. But dousing that fire seemed a crime against nature for her, and when I got to 13 and she could see I had sex on my mind -the hard ons and the squirming when I watched something hot on TV; the way I suddenly had to hide my body in the bathroom or getting dressed 'cause my dick was so stiff all the time- she just gave me the option. She just let me know if I wanted her I could have her, because she wanted me. And that's how it started.
She was only 34; had me when she was 16. I sort of remember my dad, but he disappeared when I was six. Mom was pretty good at not just turning into a slut. She fucked more guys than I knew about, but she never just went bar-crawling, never left me alone. She met guys at work, or sized them up at the gas station, but they only ever arrived after I was asleep and she always made sure they were gone by morning. She got the sex she needed without me having to open the door to strangers or hear her stumble in drunk with some slob at 1am. I knew that shit was going on with some kids and their mothers. Hell, you only had to LOOK at some of the women in this town to know it was going on.
