彼女がシャワーを浴びている間に私の義理の妹の親友を密かに犯しているのをほとんど捕まえられました(Liaandjayyy)

I sneak into my step sister's room while she is showering to fuck her best friend. She was flirting and touching me all day in secret, so I had to take my chance and fuck her while I could, she almost got us caught with her moaning but she and I managed to cum and I left just in time!
