Your girlfriend is a nympho and she wants sex constantly... always wanting to try new things... and now she's determined to find out what your deepest darkest sexual fantasies are so she can re-enact them but you won't tell her. She suspects it's something kinky after you accidentally call her step-mom when you were fucking so she snoops on your laptop while you're at work and discovers your MILF fetish. She decides to incorporate it into your evening sex and calls herself stepmommy as you're cumming. You're shocked. MILF porn is not the same as fancying your step-mom but your girlfriend disagrees. "MILF porn, step-mommy porn, same thing isn't it". No of course not and you're appalled that your girlfriend could be so perverse. You try and put it out of your head but this has made you feel kinda weird and you need some space. You go and stay with your step-mom for a few days and you can't help noticing how hot she is... what has your girlfriend done to you?! You start to realise maybe there is more to this stepmommy issue than you thought...
