I would talk to my mom about everything, including details of when I fuck a new girlfriend. My mom was always adamant "now son make sure you eat her pussy good, don't make your GF responsible for her own orgasm". I always wondered why my mom was so bent like this, then she confided that before my Dad died she was into women. Then she told me of one of her conquests, how many sons get to hear about their mom fucking other women? OMG, erection!
