Helena's Biological Cock

Dear Suzanne, I am writing to tell you in confidence about what I have been experiencing. I feel like a cat in heat at all times! My hormones are out of control, as if my biological clock is ticking hard! I NEED to get pregnant! Yesterday when my step-son came home from basketball practice I couldn't help myself! I was by his pheromones! His scent wafted into my face as he sat down next to me, and the nature took over me! He couldn't resist my touch! I began seducing him, his cock was throbbing as I removed his sweaty shorts and wrapped my lips around his cock. He was slightly nervous although I know he isn't a virgin. After giving him the best head he fucked me until he couldn't hold back giving me a massive load deep inside me! He asked if I was on birth control and when I answered him no a look of worry came across his face. If only he knew step-mommy wanted another boy just like him!
