This time I was in control, I invited son in the living room where I rode my surprised bf. We didn't change position, I blew him quickly and I rode him sitted in an armchair. I rode him slowly wanting to make it last for him, my son.

Thanks for sharing your experiences with your son NatMom. I guess a lot of the fuel for this fetish is driven by the idea of our loving and nurturing mothers engaging in lewd sexual acts. So have your sexual acts in front of your son always been vanilla or more kinky, e.g. anal, facials, squirting, rimming (giving/receiving), titty fucking, facesitting, watersports (giving/receiving)? Is there a point or boundary where you would draw the line and say "shows over sonny, go to your room" or are you both uninhibited about this sort of thing?
