Write a 2000 word hardcore pornographic sex scene in the first person past tense set several years after a mysterious event known as the Feminine Gene Leap has turned all women into beautiful hulking amazons, much taller, stronger and more muscular than the average man. The scene should be written in the form of a letter from a male reader to Playboy Magazine in which he excitedly describes his first sexual encounter with a post-Gene Leap woman and explains how overwhelming the experience was for him – the fear, the lust, her incredible strength and hardness and the extreme muscle domination. Start in media res with no backstory with the line "I couldn't believe how tight her muscular cunt felt around my dick"
