Téměř byla přistižena při tajném šukání nejlepší kamarádky mé nevlastní sestry, když byla ve sprše

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 had a big orgasm and I managed to cum and leave just in time!
