I found out that my stepdaughter is a stripper, she didn't want me to tell stepMom so I had to make her pay the price

I was awoken one night to somebody coming home very late around three in the morning, I was startled and shocked to see it was my stepdaughter coming home late, she was dressed up like a slut, and I got very upset at her because I thought she was out partying with boys.It turns out she has been stripping on the side , and she was so upset because she thought I was gonna tell stepMom. She started to seduce me and ended up getting me horny to use as leverage so I wouldn't tell stepmom we ended up fucking that night, can you believe that? I was penetrating my stepdaughter, but fucking her felt so amazing because her ass is so fat and plump. Since we fucked, I promised I wouldn't tell stepmom, but part of the agreement is she has to let me keep fucking her every time she comes home from stripping.
