I get caught pleasuring myself on my stepsister's phone gallery

Caught on my step-sis's phone, I indulged in self-pleasure. The gallery was a treasure trove of big tits, big asses, and more. The climax? A hot, homemade cum shot.

I was feeling the heat and decided to take a quick dip in the pool. As I was getting out, my step-sister's phone caught me pleasuring myself. My father in law walked in and saw me on his daughter's phone. He quickly went into shock and started yelling at me. I tried to explain that it wasn't my fault, but he wouldn't listen. He told me that I had no right to be on his daughter's phone and that I needed to leave immediately. I didn't want to cause any more trouble, so I left. Later that night, I came back and found my step-sister's phone on the kitchen counter. I couldn't resist and started going through her pictures. I found a few that really turned me on and started to pleasure myself again. When my step-sister walked in, she caught me and started to get angry. But then, she saw the evidence of my pleasure on her phone and started to laugh. She told me that she was glad I enjoyed her pictures and that it made her happy to see me pleasuring myself.
