I was minding own business when I started to hear moaning, I went to check what it was... It was my slutty step sister Sophia masturbating in the shower with the shower head! Sophia is always so horny, she ask if I wanna fuck her tight pussy real quick while our parents are out. I do more then fuck my hot step-sister, I feel her sweet pussy with my cum. Good thing we were already in the shower, my cum was leaking out of her while she was getting up.
