I always knew deep down my Son was a bit.. how do you say.. perverted.. my panties going missing.. or turning back up covered with his sticky cum in the same drawer as my clean underwear.. but I never knew.. would NEVER imagine.. he would creep into my bedroom one night whilst his step-Dad was downstairs on the sofa.. climb on top of me.. wake me up by rubbing his bare cock against my pussy.. and I did try to stop him, honesty I did but.. oh GOD I didn't realise.. his dick.. is.. SO.. HUGE.. I couldn't help myself.. couldn't stop myself from spreading my legs for him.. I tried to be a good Mother but that thick long cock just slipped inside of me and.. I had the best night of my fucking life.. even if his Dad did walk in on us as he was emptying his balls inside of me..
