The dog of my sister sleeps in my bed and I undress her, my father gives me the reason and allows me to discipline her

My sister’s dog sleeps in my bed even when I tell her not to. I’m already angry and I strip her while she’s asleep so she understands that I am her owner, the dog can’t believe it but my dad comes in and he’s right. That’s why he took her to the other room to give her the punishment she deserves, spanking her hard for that disobedient bitch. The dog gets excited and seduces me so I can fuck her with all the eagerness I have. Her wet pussy sounds delicious every time I penetrate her and her desperate moans, not caring that our dad is in the other room, excite me more and more.
