Poko Poko Imouto- Doggy Pet Aspirations-

Momo wants to be oniichan’s pet. She puts on a collar and he commands her sexually.
But he can’t control himself and takes more than she’s offering. All night sex that leaves her a dripping, inarticulate mess! Hot bukkake on her teensie eye mask!!
But no matter what he commands, she devotedly obeys with love in their brother-sister sex life!!!
