The sudden appearance of my stepsister is incredibly cute, but on the very first day she came, she asked me 'I... love SEX. I want to do naughty things all day! What about you, big brother?' This super horny high school girl doesn't even care if mom comes home early and says 'Mom's coming back soon, so let's hurry up and have sex!' She'll immediately strip and demand it over and over again as long as there's time, finally forcing me to finish inside her!
