My father remarried and got a young, busty stepmother! Unaccustomed to women, I kept getting aroused by my stepmother's cleavage and upskirt views! Despite this, when I was taking a bath, my eager-to-befriend stepmother came in saying, "I'll wash your back," and because the bath was so small, her overly large breasts kept pressing against me, causing a full erection! That erection seemed to flip a switch on my stepmother's lewdness! She hadn't been with my father in a while and suddenly transformed into a woman, repeatedly asking for me to cum inside her!
