I’ve always been a fantasist… felt that I could give my step-son more than just me as his “step-mom”.. wanted to experiment.. see what it felt like to have taboo encounters with him behind his step-dads back.. and then his step-dad left me unexpectedly… left me pregnant and with nobody to satisfy my hunger for sex.. I decided its now or never.. what’s the harm in teasing my step-son.. he may not even realise I’m doing it.. just a little bit.. an innocent step-mommy step-son kiss.. cuddle.. too much cleavage.. skirt with no panties- bent over for him to see.. encouraging him to vacation with me.. surely I could do that without serious implications? But then he comes home tipsy one night and accidentally gets into my bed instead of his own.. I won’t lie.. I was too tempted.. me and him alone.. in the privacy of my room.. in my bed.. under the covers.. I decided to tell him how I felt.. after all, he probably won’t remember by the morning and I can just pretend he’s talking nonsense.. and then something happened.. it might have been the way he looked at me.. the way he shifted under the sheets.. the way I felt his erection pressing into me.. but before I knew it I was sucking on his dick.. begging him to fuck me.. fuck step-mommy.. please fuck step-mommy..
