After the shower, my half-step sister suspiciously ran to the balcony and closed, I opened the door to her room and crept up to the window onto the balcony, what I saw made me take out my penis and start jerking off, my step sister was so sexy, she was absolutely naked with sucking a dildo, and then she started fucking her pussy until she squirt. Now I will spy on my half-step sister more often.
