Because my parents remarried, I suddenly had two stepsisters! These two stepsisters are very timid and can't refuse. I saw through their nature and boldly asked to "practice deep throat oral sex," and they couldn't refuse, so they let me. Then I thrust my hard penis deep into their throats intensely, and they said, "One more time!!"... Their masochistic tendencies blossomed! This way, we could do something even more extreme than deep throat oral sex! Inserting a saliva-covered penis into their vaginas from their throats! And I could enjoy two people at the same time! It was amazing! I couldn't stop!
